Title: ZyXEL Modems - eg VMG1312-B10A - Custom Firmware MTU 1508 Maintenance
Post by: Weaver on May 17, 2018, 02:40:21 AM
Referring to the v14-based custom firmware for the ZyXEL VMG 11312-B10A on github (https://forum.kitz.co.uk/index.php/topic,21273.msg370865.html#msg370865) that was referred to in a neighbouring thread earlier (https://forum.kitz.co.uk/index.php/topic,21273.msg370534.html#msg370534), I would very much like someone here to build it from the sources, if they have not already done so, or help me do it myself. (To do it myself though I would need to get a VM (i386 / P6) going for a build machine and a lot of help because I although a very experienced C programmer I am very new to Linux still.)

This is partly because I would really like to be able to keep this branch up to date with other fixes and updates that come from the main branch of development and from other Broadcom and ZyXEL insights.

Would anyone be kind enough to join in / offer to help us out? There are a few of us using this custom v14-based firmware now.

[Admins: would it be an idea to make this a new thread, what do you think ?

I have built it from a git clone of Olipro's repo and it successfully boots, I have yet to test it on my line though.

I found a few hiccups to get around in the build process and was brewing up to making a thread like this myself detailing them.

I have also acquired the VMG1312-B10A and VMG8324-B10A sources from zyxel and can share the dropbox links they gave me.

Next on the list is trying to build straight from zyxels sources, and trying the changes for the 8324.

Btw I presume it uses a C or C++ cross-compiler, for what? MIPSx, ARMx target ?

Yeah, Zyxel supplied a cross compiler for the MIPS architecture the BCM63168 is based on.

I got copies of both the 1312-B10A and 8924-B10A open source packages direct from Zyxel.
I built my own firmware image rather than use the 1 on git-hub.

As long as Zyxel keep sharing the complete build packages then I'd be happy to keep modifying them for 1508 MTU.

So I got around to trying to build from zyxels sources and it just worked, the issues I ran into compiling from the github repo disappeared.

Just follow the instructions that come in the source package and out pops the image.

Troubleshooting the previous build did reveal something interesting though, one of the things that failed to build initially was conntrack-tools, and watching the boot log with a serial terminal it seems even in the official firmware its not built correctly:

Code: [Select]
Netfilter messages via NETLINK v0.30.
nf_conntrack_netlink: Unknown symbol __nf_ct_l4proto_find
nf_conntrack_netlink: Unknown symbol nf_conntrack_find_get
nf_conntrack_netlink: Unknown symbol nf_conntrack_register_notifier
...
nf_conntrack_netlink: Unknown symbol nf_conntrack_l3proto_generic
nf_conntrack_netlink: Unknown symbol nf_ct_unexpect_related

insmod: can't insert '/lib/modules/2.6.30/kernel/net/netfilter/nf_conntrack_netlink.ko': unknown symbol in module, or unknown parameter

Not sure what effect not having this module working has if any, conntrack-tools appear to be for monitoring stateful packet inspection.

That's pretty horrendous, doesn't say much about their attitude to quality if they can't even get their build system bombproof. They should be greping the output and / or checking the return status and making sure that the build then fails completely and loudly.

If you think that's bad it's probably best that you don't look at the logs produced by an average Windows PC as it boots!
The attitude nowadays seem to be 'if it works then that's good enough'. :o

How does the build set that funny long-winded version number string? Could we somehow append something to it to indicate which customer version we have got but also including the base ZyXEL version string that it is based on?

Thats a good question, would be nice to append more descriptive version info that could be seen from telnet and the firmware update page for the myriad different ones, I'l have a dig around in the build package.

It shows that version string in the web GUI somewhere, there is a menu option to get to it anyway, It is iirc the first menu item in the rightmost menu.

I use it to remind me which modem I am looking at since I have so many on the go concurrently. I have made the contents of the three modemsí config files different in that respect as well as a couple of other things.

I am writing a simple ipad app to take one config file and generate derived versions of it for modem n.

Sorry if I misunderstand you, but are you finding a more detailed version string than:

 1.00(AAKL.21)C0

?

Looking at it again I realise now that I was wrong, my apologies. In the web GUI it shows two fields which are just the contents of two particular user-defined XML elements from the config file and so can be any strings you want. I had chosen to put in some text that looked a bit like a version number so that was what lead me astray, thinking it was the version number from the image file. My apologies.

No problem, was just making sure I wasn't missing something.

More detailed version strings that show up in the update page and else where would definitely be useful though.

does the vmg1312-b10a hardware support 30a? also some "official rumor" about my ISP:

http://en.globes.co.il/en/article-bezeq-upgrading-to-200-mbit-surfing-speeds-1001235706

so i'm getting vectoring if I'm on 17a too?

PS: 250/7.5 is what I expect from Bezeq :-X so i'm staying on vmg1312 as 40/3 is enough [next step is 100/3  ???]

No, it only supports up to 17a

No, not necessarily.

Your ISP appears to be rolling out profile 35b, not 30a.

*I very much doubt your ECI M41 DSLAM can be upgraded to accommodate profile 35b.

They will probably be fitting different DSLAMs. Profile 17a and profile 35b share tones so vectoring can be done over both at the same time so you may indeed get vectoring while on 17a.

*The ECI M41 DSLAM doesn't support system level vectoring, only line card vectoring.
This is incredibly inefficient and requires individual phone bundles to be routed to the same line cards.
I'd be very surprised if it could be upgraded to run system level vectoring with 17a/35b combined if they couldn't even do 17a right.

Found where the version string is stored, but it seems the webinterface truncates it to cut off anything after 1.00(AAJZ.14)C0.. so probably have to shorten the whole thing to get any useful info represented by it.

Here are 2 builds from the latest AAJZ.16 version for the VMG1312-B10A, the differences to last version are minor so no real need to upgrade if you dont feel like it. Just a version with the jumbo frames patches and another with the old telnetd binary if you enjoy having more than one telnet session open at a time, no updated dsl_phy as it seemed it only benefited me and caused more confusion than good.

Both tested to boot, but not on a line yet.

What is your experience if the sync rate following this upgrade? My sync rates are really not good compared with what they were, but I broke all the rules of proper testing and it could just be because I have resynched and nothing more. Conditions may have simply changed. I should have done a comparison test with the same firmware first.

Could someone remind me where we are with low-level DSL driver versions included? Is d26a the version number for the low-level DSL driver that is included in this latest release?

Another question: could someone help me with a recap on performance of the recent DSL driver releases - opinions on merits of the different releases?

I have a bit careful with trying to comparison test the different releases regarding performance because my three lines have rather different characteristics, for reasons unknown, and also simply resyncing a lot without even changing software can possibly cause odd annoying effects on sync rate, and that can muck up the results. It is very easy to get completely bogus results.

i have no DLM, but my line is VDSL, yours is ADSL, so I can't exactly test for you

about different releases the adsl_phy needs to be from the same SDK version [open source firmware?] of several other accompanying components, I PM'd johnson a page full of that kind of stuff that I stumbled upon on google, don't know what was done on the x1 so let's wait for his answer

i don't think x1 performs how it was seen as it's used on the 3925, leaving that aside the next adsl version that im curious about is w1

A couple of feasibility questions:

1. there is some magic incantation that will make the modem reconnect at a reduced downstream target SNRM, an override. I wonder if there might be some way of storing a setting persistently, in non-volatile storage, so that whenever the modem connects it could use this override parameter to set the initial downstream SNRM according to that value?

2. I wonder if the same tweak could be applied to the upstream direction? Perhaps this is impossible for some reason because one end (relatively) always controls this. I am not aware of the existence of any CLI command for an upstream SNRM override.

An upstream tweak down from 6dB to 3dB would help me enormously as I do struggle with upstream throughput of only 1.1 Mbps. This has got worse since I changed to the ZyXEL modems too, by about 12%. On my iPad uploading backups to the iCloud, sending files via iMessage and uploading photos is a real pain and it is the bottleneck for Facetime conversations.

I wonder if there might be some way of storing a setting persistently, in non-volatile storage, so that whenever the modem connects it could use this override parameter to set the initial downstream SNRM according to that value?

Yet another thing that I think about and would love to be able to do, however from my pokings around I have yet to find anywhere one could easily insert the magic "xdslctl configure --snr" to be executed every time the modem tries to sync. I have thought that maybe decoding and modifying the stored configuration on the persistent data partition in the file "psi" as per these posts: https://forum.kitz.co.uk/index.php/topic,21936.msg378071.html#msg378071 could lead to something... but I guess the same could be achieved by uploading a modified xml config. Maybe there is some kind of bodge to be done by inserting the extra "--snr" switch at the end of another field thats read from the config and passed to xdslctl when bringing the connection up. But one would think there should be some validation logic ensuring sane values are read from the config that needs to be bypassed, but who knows.

As the proud owner of a VDSL connection sporting 26mbps up and 1.17mbps down, I would love this to be possible and feel your pain... this kind of asymmetry means any use of the upstream has a direct impact on the downstream as a full speed set of TCP streams is close to saturating the uplink on its own. I often also have 7db of margin on the US, could easily be dropped a few db for an invaluable increase in throughput. Alas I have no recollection of being able to mess with US SNR even with ADSL1, and assume its totally out of the control of end user equipment.

Are you using "xdslctl configure --snr" on any of your lines currently Weaver? I recall reading in another post that your DS is running at 1.5db or so, is this by design or maybe due to the recent storms?

Weavers case is ADSL which the SNR tweak works but I dont know if weaver is using it. As of VDSL I think it is set on the DSLAM and cannot be overridden by end user.

Post by: Weaver on July 30, 2018, 04:12:09 AM
I have tried the tweak with impressive results.

I am wondering though if it is pushing things too far, so I ought to find out what the ratio of corrupt to total packets received is. Not sure how to do that. Could either look at modem stats, but not exactly sure, or look for L4 retx but then the packet loss or timeout that causes them could very well be for other reasons than corruption, and interpreting long periods of packet cap action with the tools that I have is a pain, hurts the brain.

With the DLink modems the downstream SNRM was usually that anyway, so perhaps they had a built-in naughty tweak factor. It would sometimes drop to 0.6-0.8dB downstream and stay there. With the old modems, each one would resync after a week or so. With the ZyXELs you never ever see resyncs.

I am thinking that the lightning might have pushed the noise floor up too much so that more FEC bits were needed. Or noise spikes could have overwhelmed the system, and it would have had to be set up with more overhead to have the required level of robustness to cope with sporadic errors of such a magnitude. I am assuming that it does not normally have to cope with spikes because there is no electrical activity of any kind near the line, no humans, no houses, no neighbours, apart from long-distance RF from: known broadcast audio RF transmitters, fish-finders, airport equipment at Tiree airport possibly, weather and marine safety info data broadcasting. If Aiseag airport by the beach at Aiseag Maol Ruibhe, between Broadford and the Skye Bridge gets going [if only!] then the level of noise might shoot up knocking out certain frequencies completely and might stuff my 5GHz WLAN channels ≥ 100.

Regarding the thing about adding the tweak command at a suitable point. I assume that that command brings the link down first, then brings it up again with the new values. And bringing it down is not what we want, so unfortunately it means a nightmare of digging, trying to find where the system initially gets certain crucial values from when it synchs for the very first time and every subsequent time. I suppose digging to find out where the magic invocation command stores the given tweak value would be a start. That location would be read on every subsequent synch.

Post by: johnson on August 18, 2018, 05:41:29 AM
So it turned out to be easy to get persistent storage of any tweak commands you like. Once I found out that commands issued with "xdslctl configure" stick between resyncs from the thread about line capping, its just a matter of having them run once on boot, no need to try and find a way to have them run every time the modem syncs.

So one line in /etc/profile to run a script (and detach it), and a file in the /data partition and away you go. Unfortunately the way the modem flashes itself there doesnt seem to be way to build files into the firmware that get extracted to the data partition, so the script thats run at boot needs to be written manually, but its only a few lines, for example:

Code: [Select]
sleep 30

xdslctl configure --maxDataRate 25000 1500 27000

Had to add the sleep as it seems /etc/profile gets run before everything is in place for xdslctl to work, don't worry its not blocking so shouldn't increase the boot time at all.

Have made a firmware for a 1312 & 8324 and I'l test it with my line in a bit, let me know if anyone is interested in having the functionality.

Post by: johnson on August 21, 2018, 01:18:31 AM
Got around to trying it on my line with my 8324, works great although I needed the sleep duration increased a little, guess the 8324 takes longer to boot.

Also refined it a little to avoid any confusion over file names, this is the only change to the firmware - added to /etc/profile:

Code: [Select]
if [ ! -f /data/boot-cmds.sh ];
then
 echo "Creating initial boot-cmds.sh"
 echo "#!/bin/bash" > /data/boot-cmds.sh
 echo "" >> /data/boot-cmds.sh
 echo "sleep 30" >> /data/boot-cmds.sh
 echo "" >> /data/boot-cmds.sh
 echo "# Place any commands here to run at boot" >> /data/boot-cmds.sh
 echo "# eg:" >> /data/boot-cmds.sh
 echo "" >> /data/boot-cmds.sh
 echo "#xdslctl configure --maxDataRate 25000 2000 27000" >> /data/boot-cmds.sh
 chmod +x /data/boot-cmds.sh
else
 echo "Running custom boot commands"
 /data/./boot-cmds.sh &
fi

So it tests if the file exists and creates a placeholder if not for you to edit. Editing does require using vi, which may be slightly uncomfortable if you have not used it before:

Login as supervisor or if just normal admin user then issue this to gain proper shell:
Code: [Select]
xtm && sh

Change to the data directory and edit using vi:
Code: [Select]
cd /data
vi boot-cmds.sh

Key "i" to enter insert mode and either uncomment the example line or write your own, eg:

Code: [Select]
xdslctl configure --snr 75
or
xdslctl configure --maxDataRate 25000 2000 27000

Escape key to exit insert mode and ":x" to save and quit. You can test to see if the command works as expected by:

Code: [Select]

Should do all this with the modem disconnected from the line to avoid causing several resyncs. Now reboot the modem and check again with "xdslctl info --cfg" to make sure its applied at boot.

I have tried putting faulty commands in the boot-cmds.sh file and no harm done to the boot, so unless you put something seriously bad like "reboot" in there I cant see any issues. If you wish to disable it just comment everything in the file out or just delete it, another placeholder will be made after a reboot with nothing but the sleep command in.

As always disclaimer that even though I have tested on several modems you are flashing at your own risk etc etc.

With just the jumboframes patches and this addition for the VMG1312-B10A:

Thank you so much for your hard work! And likewise for the 8924 please if differing in any way from the 8324. Do you see any benefit from the x1 adsl_phy for VDSL FTTC, approx 450m from Huawei cab? Solid 80/17.5 speeds on stock v18 firmware. No ipv6 though (as per normal with BT Infinity and the 8324/8924 I believe). Cheers!

This is for bridge mode. 1508 MTU can be done without this when using as a router.
I don't believe this firmware makes the changes persistent when used as a router and a command needs issued unless that has been resolved.

The newer adsl_phy seems to corect some Vectoring bugs but no other obvious performance improvements.

Sure thing, I'l make one for the 8924/8324.

Just for clarity, this latest feature for running commands on boot is only really useful if you wish to apply a cap to your line in a persistent way or as in Weavers case, for applying target SNR changes to an ADSL line.

Several people tried the x1 version, it did not appear to offer any increase in speed or stability on either VDSL or ADSL, its only benefit was fixing an odd bug that I have experience on a vectored line. Of course you are welcome to test on your line but from others experience its unlikely to improve things and adds another variable to any troubleshooting you may be doing.

Indeed, this change only allows the execution of commands on boot, the 1508 commands that need to be run when using these devices in router mode have to be applied to the interfaces that are brought up once a ppp session has been made.

Post by: johnson on August 24, 2018, 03:10:45 AM
So it seemed like a good time for a consolidation post.

These are firmwares based of the latest release from Zyxel, AAJK.16 for the VMG1312-B10A & AAKL.24 for the VMG8924/8324-B10A.

Each folder has several firmware with naming as follows:


-jumboframes
Patches applied to allow 1508 byte packets to pass from a router to the modem in bridge mode. See this thread (https://forum.kitz.co.uk/index.php/topic,21273.0.html) for further info.

-oldtelnet
Including a slightly older version of the telnetd binary that allows multiple concurrent telnet sessions. This is useful if you want to be able to log into your modem while running monitoring software such as DSLStats. Basic comparisons of it with newer versions indicate that the only change made by zyxel was the disallowing of multiple sessions.

-customcmds
A small change to add the execution of a user modifiable script located in the persistent /data partition during boot. This is useful if you wish to add a cap to your line to possibly remove banding/reduce retransmission, in a persistent way that survives reboots. See this post (https://forum.kitz.co.uk/index.php/topic,22086.msg379683.html#msg379683) and thread for more info on reasons to cap. It is also useful if you have an ADSL line and wish to have persistent storage of changes to your target SNR. Please see this post (https://forum.kitz.co.uk/index.php/topic,21545.msg381240.html#msg381240) for how to add the commands you want.

-x1
These firmwares contain a newer version of part of the broadcom DSL driver - adsl_phy.bin. It has been tested by several users and does not seem to offer any speed or stability improvements, however it does seem to fix issues I have personally encountered on a line with vectoring. If you have vectoring (unlikely unless you live in a BDUK (https://www.gov.uk/guidance/broadband-delivery-uk) area) then these versions are worth trying.

-x6
As above but including the newer A2pv6F039x6 adsl_phy.

VMG1312-B10A
https://www.dropbox.com/sh/c5no9h8ckyp2i4i/AADwAR6oVbzwFjtE-bLdy81Za?dl=0&lst=

VMG8924/8324-B10A
https://www.dropbox.com/sh/4xfif7ssq8pdq6u/AAChWy_N8UIVmpqQizmI2CUra?dl=0&lst=


They have all been at a minimum tested to boot have the correct changes on my devices, but as always you are flashing at your own risk and having a backup modem is highly recommended.

Edit: Change dropbox view to list

regarding the graphical stats web server build, a feature request: How about a couple of links, maybe inside a <ul><li> etc which just point to /data/whatever, the textual stats report pages, for convenience. It would be a finger saver.

Also musing about another ui convenience request, could there be any way of arranging for a preceding call to/getdata to happen automatically before these individual per-command requests? If asking for such a thing even makes sense.

--

I was thinking about the on-boot custom script execution feature. There's nowhere appropriate to store the custom boot commands in writeable flash. Could we pull in a boot script by fetching it from the internet somewhere somehow ? Pull its content from a download from some fixed url and then run it, or perhaps even better fetch a well-known dns TXT record and execute its contents ? But what would the 'standard' well-known external reference be ? Could such an external reference be made variable by defining it in a config xml entry somehow, perhaps re-purposing an entry.

Or go further and simply put the whole custom script content into the config xml somewhere?

I think it is possible to downgrade, but it may well require the .rom file from the firmware archive file you downloaded to be applied first using the restore configuration option.  It is simply a standard configuration file.

Others may be able to advise better than I.

Thereís an emergency boot mode that you can force it into with the appropriate hole-poking procedure and magic incantation. I donít know if that would be relevant with this.

Burakkucat or Johnson may be able to help with that.

There is a procedure for killing the .rom file and indeed as vultura said that might be the way to go. High priests can advise with .rom-killing.

The convenience links, urls I mentioned earlier, would be a nice tiny finger-saver. Could I even do it myself by modifying the html file, by code in the custom boot cmds thing? It would probably be too late and the web server would have loaded that html into ram and be running that copy permanently so it wouldnít make sense, I presume. I would have added some
Code: [Select]
<a /> elements into the html with
Code: [Select]
sed perhaps.


More wish list:

2. I wonder if the graph could have a range limit. Sometimes, when things go wrong, huge SNRM values get introduced as giant spikes, and dominate the scale making it impossible to read the normal items as they are so tiny by comparison. I donít know what to suggest about the details of sorting that out and I donít know where to set range limit parameters, or just to hard-code some seemingly sensible range limits since we know what SNRM values make sense, from experience.

3. What about logging attenuation ? What do you think?


ó Note: I am finding the stats logging and graphing thing so incredibly useful. Iím using it all the time and it has already helped me with a recent intermittent high-resistance fault on my line #3 which is now sorted.

ó The easy access to the raw ZyXEL current stats at http /data/varStats is fantastic. Iíve used it in a program in my iPad which queries the upstream sync speeds from all the modems, calculates downrated IP data rates derived from these numbers them and puts these rates into a dynamically modified Firebrick router config file which is uploaded into my router.  This ensures that the router drives each modem at the correct max speed, and the total upstream traffic gets split between the links in the right ratios according to the linksí differing speeds.

So thank you so very much indeed for your work!

Indeed /data is writeable and persistent, not sure of its size though. There is about 155K of certificates and things there, but I wouldnt want the the log file written there every 30 seconds. The html/js/logfile etc is all copied to /var/tmp (in ram) at boot, so a reboot will unfortunately lose the days log.

Have a look at the current state of the interface I have running on my VMG1312:
https://imgur.com/a/DzvYY9E

Buttons for each graph, options to scale linear or log and for tone range data either full or scaled to the top tone with bits used.

Also a button that goes to the data folder where you can select each raw stats file. They all update on access now so no /getdata call required.

Playing with having a side bar with useful info next to the graphs, will look something like this:

Does this sort of interface appeal?

Are there other giant spikes than the ones caused by the bugged upstream SNRM (going to 100 for negative values)? The log/lin button helps with visualising graphs with spikes in, but certainly clipping would be good.

Can certainly add attenuation, I imagine the graphs will be pretty boring on most lines but maybe they will offer some insight on lines with problems like yours.

One more thing I have got working on the testing version is in browser zipping of files, so one click to get an archive of the log file and all stats, should be useful for capturing events easily.

Wow, just a bit. That looks fantastic. You have been working hard. Very appealing.

I had a problem where the attenuation jumped up by 8-10dB and so Iím thinking that that could possibly be a common pattern where there is some fault condition? Of course as you say, deathly boring for the most part.

> Are there any other giant spikes

No, I am certain thatís the only source of them. Iím still running that version, canít remember where we are now.

Regarding zipping, does the small webserver used for stats support gzip encoding for http?

Ok will add attenuation. The 100+db spikes should be sorted by the fudge of subtracting upstream SNRM values from 100 when > 100, sure there are no cases when SNRM would be that high else where so no problems.

Good idea. I dont think the server supports dynamic compressing of files, but maybe with the right headers set it could serve pre-gziped ones - should save some ram! But the zipping I was talking about is in browser using a javascript library (96K - 28K gzipped  ;D) mostly just to take a snapshot of the various stats files and logs and present a single archive to download. Good for debugging as with the 100db spikes you had and with the possibility of being able to "upload" (not really because its all in browser) archived stats to view at a later date.

Only for adsl, dslstats has an advanced tweaks page for this or manual telnet - adsl configure --snr X (X=value of snr reduction - 50(3db),75(1.5db) etc...).

The command get rejected/ignored by the DLM side for VDSL.

Router/modem's with Infineon chipset can adjust the VDSL snr eg.Draytek, so would assume it is Broadcom related.

Without using questionable chipsets there is no way to manually change SNRM target on VDSL lines. Those that can do not adhere to standards and will probably give you worse sync speeds than you had without messing with it.

If you wanted to increase your SNRM with a Broadcom modem, you could set a rate cap to reduce your speed, and then you'd end up with a higher SNRM.

The easy stats interface is just so excellent. Am using it as an API all the time. Apart from the sheer usefulness of it, as an api I can now generate automatically customised sections of config for my Firebrick router which contain upstream speed limiter values which the router requires. These speed values are derived by querying the modems using the Johnson easy-stats api. The router needs these to control the fractions of the split of traffic going to each modem according to its own speed capability. Before I had to set these numbers by hand and query the required numbers by hand. Now everything is automated including configuring the router according to the possibly changed speeds as the program can upload changed config into the router. Unfortunately I donít have a service process / daemon running continuously to oversee this and keep things up to date as I donít have a suitable box to run it in. The program is running in an iPad and I canít use such a machine to do that anyway. But aside from that, itís now just one click to update the routerís configuration to match changed modem upstream sync rates.

Having the easy-stats interface avoids the need to log in, which is irrelevant anyway and would be annoying. It would also be a minor potential security threat. For an application programís use, if it logs in to the web admin UI, you would have to store some account username + pw somewhere, required for it to get into the modemís admin interface, and the more places where you store passwords the more possibilities for trouble.

I havenít yet tried writing an iPad Shortcuts program to log in using the web UI, and I donít know how much pain that would be.

What I would like to do is test whether or not I have a johnson-easy-stats-api-speaking modem present or not. I want to handle failure conditions properly which include: (i) no modem, (ii) wrong kind of modem (one which doesnít speak easy-stats), (iii) no speed value available because the link is not up. And I hope that thatís the complete list.

I have a problem with the program hanging in some of the error cases. It maybe that I canít fix some of the hangs if they are due to a lack of error handling in iOS Shortcuts library routines used to talk to the modem.

I am however wondering if my application program could be made more reliable and more intelligent if it explicitly detected lack of an easy-stats speaker rather than relying on error mechanisms reporting errors or getting a bad value back from http-based queries and checks on its value turn the situation into a Ďfailí where the fact that the return value is garbage is because we do have some modem, but it is a non easy-stats speaker, could easily be the wrong modem altogether - one of my DLink backup/swapout modems, for example. This doesnít remove the need to do error handling properly. But if I canít get error handling the way I want it, then I can perhaps do a workaround for some common cases, and such a workaround might improve things for the most part.

If there is a non easy-stats-speaking modem present, it will be that the wrong model of modem is connected, in my particular situation. So what Iím thinking of doing is poking it with some harmless query first. I could do a getdata, and check that it returns "DONE".

So in future releases, could we keep the getdata / "DONE" protocol? Even if it doesnít do anything any more, it is a nop that works as a very useful presence-test.

For me though, using the pre-poke-with-getdata strategy might just replace one error-handling problem with another in some cases and it might easily be a stupid idea. There are two questions, one is: can I just fix the error handling anyway? And the second is whether or not this will improve things in practice in a real test with the wrong model of modem present. I suspect I am likely to replace one kind of hang with another. I can hope that with a DLink modem present the http queries will fail straight away, with an error code, and if so I can pick up on that without the pre-poke strategy, and if not then Iím probably stuffed anyway. But Iíd like to keep this nop in the api, just in case, if thatís ok?

Promise I am still working on this! Have been side tracked by a few things though.

I have gziped html/css/js working with the tiny mongoose server, turned out to only be a few magic lines required, setting the media type for js.gz etc and setting the content type to gzip in the headers for responses to the directory containing them.

Also have an example version with SSL working, although it required compiling OpenSSL for MIPS and then statically linking it against the web server making the binary much heavier at ~ 1.9MB. Not sure how useful this is though, how many people actually use https (and click through the cert warnings) to access the default Zyxel GUI? Guess its a good idea for the future if we add a privileged section that can actually change settings on the modem.

The main hold up came after I started trying out the graphs on my (old) android phone, basic 24 hour or 4096 tone graphs were seriously sluggish to load. I'm not a daily chrome user, but their debugging tools are out of this world - a usb cable and "developer mode" selected on an android device and you can see detailed performance graphs for how a site loads natively on your phone on your desktop. This revealed that Chart.js is not the fastest library, so I'm looking for another. So far dygraphs is the winner, its slick and has lots of options to customise without being a nightmare to draw a basic graph and best of all its fast, a 2.9 second graph draw (on the ancient phone) down to 0.8. So need to get around to changing everything to use this.

Also, even though its probably a fools errand I have been trying to shoe horn enough of the VMG3925s build into the 1312s to get the later kernel (3.4.11 vs 2.6.30) and so broadcom dsl driver running. So far I have it booting the kernel and most of the modules loading, but nothing actually working.

@Weaver
Of course /getdata can be left in place if its useful. Was also thinking about something you mentioned in another thread about automating resyncs. This functionality could be exposed via a rudimentary API with basic authentication tokens or some such. Does 'shortcuts' let you manipulate the http headers?

@hacktrix2006
Glad you like it! Currently only has a small subset of DSLstats features. SNRM, FEC & CRC for 24 hours and current graphs for SNR, bitloading, QLN etc. USB storage for longer time periods is a definite target, but for now keeping everything as simple as possible, just viewing in the browser and saving from there is where I am at.

how is the custom kernel doing? I am thinking of setting up something like DSLStats on my WRT32x but not sure if A it will work or B the CPU (Dualcore) would handle it as well as the internet traffic at once. I am only using the VMG1312-B10A as a modem, will continue to do so once i get Fibre (First order just got rejected).

@johnson about the remote reboot thing. Yes, I have done Ďbasic authenticationí before with the iOS Shortcuts framework. I already have written library routines to do everything, so it would be a good choice for me. Could we use the existing password out of the current ZyXEL config - would that be more work or less work?

[A recap post. Duplicate of a post in another long thread.]

This post at an earlier point in the thread (https://forum.kitz.co.uk/index.php/topic,21685.msg384925.html#msg384925) contains the download link (https://forum.kitz.co.uk/index.php/topic,21685.msg384925.html#msg384925). That is the version I am using on all my (many) modems. Rock solid, ignore the reports in posts immediately following as I just made stupid mistakes and failed to install it. It is just superb.

That version has A new version is under development.

I use all of the features of it all the time as I donít currently have a suitable machine that can display stats via a telnet-based protocol because of limitations in the tools I use. I am iPad-only these days and I have not learned Python yet, which is probably the way to go for easy casual app development on iPad.

Another opportunity to thank our kitizen and friend Johnson for his outstanding (and continuing) work on this.

I'd be inclined to test this on my 8924 in bridge mode, however seeing that I have the patched v.24 one with the babyjumbo frames, the multiple telnet sessions and the new DSL PHY driver can I ask if we can possibly have the newer version with the webserver stats incorporated? ...and while we are at it can I ask how any updates off the current 1312 fork are shaping up? ;)

Experiments with docker have given pleasing results, with this minimal Dockerfile:

Code: [Select]
FROM yamamuteki/ubuntu-lucid-i386

WORKDIR /tmp

RUN sed -i 's/archive/old-releases/' /etc/apt/sources.list

RUN echo "dash dash/sh boolean false" | debconf-set-selections

RUN DEBIAN_FRONTEND=noninteractive dpkg-reconfigure dash

RUN apt-get update && apt-get install -y unzip bzip2 patch \
    g++ flex bison gawk make autoconf zlib1g-dev libcurses-ocaml-dev libncurses-dev

I have a fully working build environment for the 1312/8x24. So with a working docker install its 2 commands to build the images on linux/mac/windows. (  :fingers: )

Have also succeeded in getting a 3925 build running in docker, but its a little more complicated.

Anyway, have also got 99% of the the way there to a nice helper script that will use this docker container to build any version of the image required, jumbo - telnet - x1 - x6 - stats etc. Works great in linux, but need to try on other platforms.

Has anyone got the new source package we all requested in january(?), I believe the date they said it would be available was some time in june, but have not been checking my spam email box and they always seem to go there. Would be nice to include the latest source.

A few questions about the toolchain supplied by ZyXEL: the cross-compiler for MIPS target was mentioned.
  • where does the compiler come from - is it included or a reference and a separate download ?
  • is the target MIPS32 ?
  • is the compilerís code generation any good?

Sorry for not looking at this thread in an age Weaver!

1. The toolchain is supplied with the source code package from Zyxel, others have rollled their own and produced working binaries (that I have tested). The cross compile tools are mips uClibc 4.4.2-1.

2. Yes the target is MIPS32, the BCM63168 has 2 400mhz MIPS cores.

3. I have no idea, all I know is that it works. The build is Makefile soup, so I am not sure if the best compiler flags are used, but I should look at that.

Since the previous post, I have been running this same VMG1312-B10A 2018-10 version (https://forum.kitz.co.uk/index.php/topic,21685.msg384925.html#msg384925) on all my modems. I have since tested a new very snazzy JavaScript UI for the SNRM stats graphing function by remote access to a UI-test-box server, but as for modems, I have not acquired a newer released modem build. That October VMG1312-B10A release has worked superbly well.

Iím now running the 2020-02-xx (mid February) release of the VMG 1312-B10A build. As Iíve said earlier elsewhere, itís superb. Many thanks yet again.  ;D  ;D

FYI I have my own "my-ref" version numbers for new Johnson releases; this number space of mine doesnít tell you which build variant it is in the sense of which features are in/out amongst the many build options. The weaver-ver numbers are


A couple of feature requests arising from something that was discussed briefly some while back:

1. Would it be possible to take your Johnson build version number and append it to your build version identifier string as I see that the build version id string / bin filename is now visible in the web UI?

This is info something I would like to use in order to :
2. Could you add entries to the main stats numbers page so that all the component build version strings and Johnson build version number are showing? That would be really handy as I then donít need to log in. Note: Iíd like the Johnson build version number to be shown separately please.  :)

3. And the same version info components as above, making it structured in machine-readable format such as eg "<field-name> ":" <field-value> <LF>" or whatever, with easy-to-parse syntax, and returned by an http request such as "http://192.168.1.1:8000/Version/". The field names can be whatever you like, something suitable to explain the various component items of version identification info exactly as in #2 above.

That way I could query the build version number most easily.

Post by: Weaver on March 29, 2020, 08:21:59 AM
Very vague possibility of a bug report. After I upgraded to a new 2020-02-xx version of Johnsonís custom firmware now with a vastly enhanced multi-graph web UI as opposed to the 2018-10-xx single graph version I had been using before I got very confused because it looked like the upgrade had failed. I couldnít see the new sophisticated web UI, I was still seeing an old-style web page but digging around in the ZyXEL admin web-UIís menus I could see the new expected version string. I tried all sorts of things floundering. Then I discovered that it was simply a matter of stale cached content in the browser. Somehow getting the browser to really refetch the latest page at http://192.168.3.1:8000 was all that was needed to reveal the new style stats serverís numbers page finally.

Apologies if all the following is old news to you, which Iím sure is probably the case, but just in case itís useful, here goes:

So it looks to me as if the cache control info is wrong. See https://www.mnot.net/cache_docs/#SCRIPT In fact the whole article if youíre not au fait with web cacheability and caching-friendliness. It looks as if there is caching of stale data going on within the browser here, and Iím guessing itís because because cacheability headers are missing.

It would be a really bad thing to try and disable all caching by fighting the browser, I recommend the best thing to do is to add Etag http headers to the generated web pages. (See above url.) A good web server will do this for you when it can and Iím assuming that Mongoose (is that right) will do so but only when it can, and here youíre taking generated content produced by an application and turning it into web pages, not serving up files from the file system and so in this case webserver engines need to be told what to do as they canít generate cacheability headers automatically from metadata about a served-up content fileís size, last-modified date and even a hash of the file content. I have written this kind of code in a server-side module before. Again, the best thing would be to add ETag headers whose values are cheapo cheapo hashes (ie fast and not cryptography-grade) of the entire generated data itself which is the content of your webpage. That way the browser will know when the content of the web page has changed because the etag hash will change and if the value is not changed then the browser can skip a repeat download. The system is then bomb-proof and thereís no fiddling about with a guess about freshness times.

In this case the problem was I assume the reverse, if my guess/diagnosis is right, in that old information which was stale was regarded as good by the browser either because there was no cacheability header information published by the web server or else the cacheability headers were wrong, which is unlikely unless there was a definite bug. When the content of the page changes then the ETag value computed from the page content, which is the cheap and fast hash, becomes different from the ETag value last seen by the browser and so the browser knows to do a download. Since the browser, so it seems, was unwilling to download the page in question (in this case ":8000/") even though the relevant page content had in fact changed inside the server my guess is that there were no ETags. Maybe there is an overall default in force for a long cache time which is totally inappropriate here.

I think back then I was still seeing the browserís cache which contained a webpage produced by the old firmware and the browser was ignoring the fact that the content of "/" was by then different on the server. The server presumably got a get http head request or got a conditional get which returned not_modified. There are various if-modified queries and conditional requests, which check dates if applicable, or else ETag values, if not using dates in cacheability headers, as here, with non-(static)-file content being served up.

Hopefully thatís all you have to do. One albeit long line of code. I had to do a lot more than just adding calculated ETag headers in the server application code but my circumstances were different.

Another bug report: on one of my modems, the axes in SNRM are showing extreme values such that the current dataset will not be visible. I can scroll or pinch to head to the area where the data is but itís either too far or it simply is not to be found. A reboot did not fix this.

Do we need a ranges state reset control in order to be able to get back to sanity if the user has scrolled right of the visible dataset? I may have dropped the iPad face down so it got bizarre multitouch events. I would suggest not, just donít allow scrolling/zooming right off/away from the range of visible data.

Depends which modem you have. Do you have a separate modem and router? The ones with easy stats web server capabilities have Ďstatsí in the filename. And yes, you just upgrade firmware using the normal router web UI as usual.

Further to that previous bug report: the axes that are scrolled off to extreme values are those that show date-time. The horizontal axis on SNRM is showing 1 Jan 1970. A reboot doesnít get me out of this.

Weaver thank you for the excellent and detailed feedback, the changes to version numbers and visibility all seem reasonable, I will have a good look at the best way to do it. Thank you for bringing up the problems with caching, I have experienced similar even with real projects like openwrt, but it seems to have slipped through the cracks with my tests of the firmware.

The time problem I thought was under control by having the stats logging script detect changes of over and hour and updating all the stamps in the log file, while also using the modems current time and calculating the difference to browser time to display. I had issues with the stats logging beginning before boot had completed so including stamps at 0 seconds since the epoch (1970) but I thought I'd stopped that happening.


To start with I really want to fix the graphs broken by incorrect timestamps, it would be great if you could upload the result of hitting "Save" on the stats page of a modem with the problem present (unfortunately I believe its over the limit for attachments with 48hrs of data so will require dropbox or similar).

Hereís a saved dataset with the problem showing. The server has not been running for any length of time at all; hope that doesnít matter.

BTW this is downloaded into iOS Safari on my iPad which is set to a UTC/GMT not BST. I canít imagine that that makes any difference, but there is one Ďjust in caseí odd thing about my system. I have installed the new version in more than one modem and iirc some modems donít show the problem and only one does. Guessing completely; one iPad fell onto its front on the bed so was getting pinch/scroll multitouch input events all the time while I dozed off. That could well have sent lots of events to the web server because a graph was showing in Safari at the time.

Good point. Perhaps delete my later post? I suddenly realised that since I could go back and edit the original post, I could perhaps change the attachment, so I did so, went back and attached it again and checked it afterwards.



I rebooted the server on the modem but I was still stuck in 1970 on the SNRM vs time graph and a reboot didnít fix the problem. I donít know where the state info is stored otherwise I could delete the state info and restart the server.

So it seems once the state is bad then youíre stuck with it, given my level of ignorance; I canít see that even reflashing it will reset the state to restore sanity?

Bug aside, itís a superb piece of software. Greatly impressed- thank you for all your work.



Off topic: half iOS question ; whatís the easiest way of me uploading one of my graphs as spring did there? I can of course do lots of screenshots and crop them, as I usually do. I would have to give all the bitmaps to my wife to make use of her expertise if I wanted a collage of them, tiled, as spring did back there.

QLN idk, but for SNR it's both interference and modem code tendency to do that. idk what else to say because i don't know how to solve such a thing. what version do you run? x6/V ?

Post by: spring on April 02, 2020, 11:37:18 PM
yes x6 must be good. the exception would be if V turned to somehow be better which idk yet. or if x6 has some exceptions like x1 had. x1 ran better on some days but had days that were sometimes two or three-fold Forward Error corrections. i associate that with timeouts and stuff like that. it implies less stability in general.

only testing can know and it's still a personal result. i didn't really have a problem with x1 it's just that it performed slightly worse overall. [for non-vectoring lines like mine, that is]. i don't like x1 at all...

my dad also uses the internet so ill ask him and also see how games perform. i don't have anything new to add as i already know more or less how the SNR graphs will look and what error counts i would get. it's just that i didn't test to see what error counts V has during this time of external interferences. if only they were completely gone.

edit: x1 also had better bitswap, but sometimes sync'd with some bad bitswap and got stuck like that. that's why i need to re-sync x6 after 2 weeks and run it for another week. i think bitswap doesn't have a deeper meaning like SNR graphs. it's just what it is, unlike SNR graphs that can actually indicate whether or not there's something wrong with the modem code.

edit2: truth is, only long term experience of usage really counts in the end. not the error counts, SNR or bitswap graphs since those are ultimately meaningless. any modem code will always have ups, downs, and variations between different people.

edit3: i won't use dslstats again because it force restarts my 1312-b10a after a while, but johnson's stat graphs look a bit different than dslstats' graphs. that's why i can't just say "V's graphs looked better" even though i have old graphs.

edit4: any idea why dslstats did that to my device? the crash appeared to be random. did it ever crash your device? i prefer how dslstats graphs looked. more detailed and accurate than stats-server.

edit5: i'll use DSLStats before i restart the device since it has better graphs. that way i won't risk a crash. i also speed tested x6 and i can't imagine it working better. well i'm talking/thinking too much too soon

edit6: ISP is capped at 60mbit downstream. [i'll eventually call to update the package to 100mbit for free, maybe even next week. my line has 95mbit almost all the time. generic microfilters, no ferrites, generic 2(?) meter DSL cable. i used to have a better line with 110mbit but it was stolen... ISP gives 3mbit upstream for everyone]. if i connected the modem to the master socket i'd have no errors and 100mbit. but how can i pass cat6 through the walls of the house? stuck with using powerline adapters. i know, they emit unhealthy electromagnetic radiation.

external interferences are back, line lost sync at 4:00 AM and SNRM graph showed a dip in upstream.
guess i won't be able to run it for 1-2 weeks so i'll just switch back to V to compare.

edit3: first spikes in SNR for V: https://imgur.com/a/24F3NB1
doesn't look good at all. x6 must be better.. i think. maybe V stabilizes to be on par. we'll see.

edit4: no more spikes but the last tones still logically point downward. not linearly though. i think at this point it's safe to say only usage like browsing, gaming etc has any value. total SNR is ~9db for both. error stats still matter though.

edit5: error rates looking pretty good.

i'll post about the final results when i have them. i think enough information was posted by now.

edit6: it seems i do have DLM but it never reacts to any resyncs. only error counts and apparently the last 10 days had enough errors to limit my sync to 80. guess i do have some really smart DLM.

So I'm not sure exactly why this is, or whether it is my imagination - but when using a VMG1312-B10A with the custom X6 firmware (I have vectoring on my line), the Internet feels less responsive. I've set the MTU at 1500 on my OpenWrt TP-LINK Archer C7 but still things just feel more sluggish.

I've plugged my Huawei HG612 back in and things are feeling normal again, what could be going on here?

Post by: spring on April 04, 2020, 04:34:39 PM
X6 can glitch out sometimes. like X1 had the same tendency. that's why i decided to test it. i don't have DLM unless errors are so high they repeatedly [10+ times] drop the sync. i can test whatever i want with no consequences.

V is more stable. no doubt about it. i'm even seeing it in error counts. like i said:
Quote
i think resilient is the word to describe x6. i've been using the internet, gaming, and my dad as well. no complaints from him or me. downloads are stable. the best way to describe x6 is smoothness. for V it's more like "old fashioned cautions" that get through the hardest times. that's why x6 might not work for everyone. especially since (theoretically) it's a bit incompatible with dsl driver d26a. in practice i haven't seen that "incompatibility" manifest yet. [except maybe in SNR graph spikes... dunno yet]. it also bitswaps much better than x1 and even V. x6 is less conservatory than V. if that makes sense. so it's both more prone to errors but also better results. whether that potential is worth it i dunno yet.
it's not for everyone. X1 had the same problem. not for everyone.

maybe not even for me. i don't have the results yet.. all i know is i don't have vectoring so... might be useless for me to use X6.


edit: i misread you saying that you have vectoring as "non-vectoring". sorry. it then must be the incompatibility with dsl driver d26a.

i guess that one guy who said: "don't swap new modem code with old dsl driver" was right. actually, he said something similar to that.. not exactly that. but still.


i guess we do have results? don't try this at home.

lmao..


Quote
the Internet feels less responsive.
i've experienced that too. i thought it was my ISP... hah. guess it's not actually x6, it's the incompatibility with d26a.
maybe zyxel do other stuff before they just "change adsl-phy.bin". i don't know. i just know that,.. yes, the testing must be futile because it must be so simple.. so simple that the original modem code must be left in place for stability.




edit: if you compare X6:
(https://i.imgur.com/YtKnnA2.png)
to V
(https://i.imgur.com/I7oDCU6.png)

i think V does better in upload for example.
maybe that initial stutter with X6? idk. could be the ISP as i haven't tested it without the ISP. [i can do that though]
i'll switch to x6 in 2 weeks and see again if i have stutter etc because then i'll be sure it's not the ISP/line etc.

edit: don't mind the V having just 3.0 upload because my line has 5.0 upload. it's just the ISP ending up with 3.0. the graph is the only difference between the two.

You state that as a matter of fact.

The reality is every line is different and while your line will work best with 1 DSL driver that isn't necessarily the case for everyone else's lines.

I found no difference between any of the different DSL drivers but choose and recommend the original that came with the modem firmware.
It has the correct matching kernel.

The only reason I changed firmware was because the original had issues with vectoring. Has this now been fixed, if so I will use the original.

choices choices... maybe just get a 3925 or whatever that was. i think 3925.
x6 was taken from 3925. or something similar to 3925. i don't know zyxel modems except 1312.

What is the latest official firmware for the VMG1312-B10A?

Looking on the ZyXEL ftp server (http://ftp.zyxel.com/VMG1312-B10A/firmware/) I see VMG1312-B10A_1.00(AAJZ.17)C0.zip

[Edited to fix the link. (Thanks to tickmike (https://forum.kitz.co.uk/index.php?action=profile;u=329) for spotting the error.)]

Does anyone know how to parse and analyse the long ZyXEL version strings that we see in their filenames?

And I could do with a recap on the meaning of x1 vs x6 vs etc

Regarding the bug where graphs that involve a time x-axis are broken/absent/stuck on 1970; this only happens on my modem #3, not the others. Iíve tried everything I can think of to fix it. Iíve reinstalled the firmware, deleted the directory tree where the log file and all the application data lives - if I got it right, anyway I think I deleted at least enough stuff as I got a Ďnot foundí error message from the app, then reinstalled the software but cannot fix it.

I donít understand whatís different about that modem. I thought it must be something in the ZyXEL XML config file that is somehow different, so I diffed that xml with the one for modems #4 and thereís no difference so thatís out. (No difference apart from IP addresses being 192.168.n.* as necessary for the different modemsí slots, .3.* instead of .4.* etc)

Suggestions as to whatís going wrong and suggestions for a workaround?

I can always go back to the earlier software version for this modem, then I will have SNRM graphing back.

That suddenly makes me think. Why does the old software (autumn 2018) work on modem #3?

Feature request or howto/tip request - no idea how to define this

Seeing as I have four modems, at times I keep having to edit the url at the top address line in my web browser, which is Safari iPadOS btw, in order to flick between the modems when I want to compare results. This is really fiddly and annoying.

Can anyone suggest an easy way of doing this? Or else design a way of adding an assistive feature into the UI so that this can be made into a feature request for a new software release? I have no idea how to do this and itís cheeky asking a lot of our friend Johnson and the rest of you?

The only think I can think of would be a list of urls which you include in a config file somewhere, somehow. The list of urls for me would be something like
    http://m1.csw.me.uk:8000/*
    http://m2.csw.me.uk:8000/*
    http://m3.csw.me.uk:8000/*
    http://m4.csw.me.uk:8000/*

The current page url might be something like
    http://m1.csw.me.uk:8000/#Stats     for modem 1, say,
and the * denotes a part of the current url that is taken from the corresponding part of the current page; ie itís common to an old page and a new page when changing from one modem to another. That part is initially null; if not then we would need to enhance this syntax.

The listís entry count tells us how many modems there are.

The domain name I quoted is just a convenient alias for 192.168.x.1 for each modem and a literal IP address could be used instead.

The UI might be something like a load of links in a horizontal menu on the right of the menu strip at the top, the links being named m1 m2 m3 m4 etc, next to where it currently says "full"/"used" and "lin"/"log". An alternative UI might be a floating or drop-down vertical menu.

Possible syntax simplification, no * : It might be that you can just forget the * markers and assume that the current url is always longer than the current list entry and you compare the final part of the two, so for example the current list entry might be
    current list entry = http://m1.csw.me.uk:8000/            and the
             current url = http://m1.csw.me.uk:8000/#Stats
So the difference calculated, final = "#Stats" gives you the extra amount of text that needs to be added to transform a url for one page into that for another modem. You obtain this by reverse-comparing two strings, backwards from the end. Does that work ?

Example: So if you want to go from the current url above, which is for modem 1, to modem 3 say, and the current per-modem list entry is as above, then :
  list entry for new modem  = "http://m3.csw.me.uk:8000/"
     dest url for new modem = "http://m3.csw.me.uk:8000/" + final = "http://m3.csw.me.uk:8000/#Stats"

To switch from one modem to another, the user can either click on one of the m1 m2 m3 links, or use forward/ backwards or edit or type in a url or goodness knows what. Itís only in the case of clicking on the n1 m2 etc links that we need to do the calculation of new dest url based on current url and other arguments.

I have absolutely no idea about how to write the code; my javascript isnít at all up to it and I havenít done any in 15 years.

I really donít know how to include the list in the config. Thatís somewhere else that Iím stuck.

A local web page? eg

Code: [Select]
<!DOCTYPE html>
<html>
 <head>
  <title>Modem Monitor</title>
 </head>
 <body>
 <p>
<a href='http://m1.csw.me.uk:8000/' target='routerui'>Router 1</a>
<a href='http://m2.csw.me.uk:8000/' target='routerui'>Router 2</a>
<a href='http://m3.csw.me.uk:8000/' target='routerui'>Router 3</a>
<a href='http://m4.csw.me.uk:8000/' target='routerui'>Router 4</a>
</p>
 <iframe name='routerui' style='width: 100%; height: 768px;' src='http://m1.csw.me.uk:8000/'></iframe>
 </body>
</html>

I looked into getting the url of the current page in the iframe to extract the anchor (so it would link to the same page when you click on different routers) but it seems to be blocked by modern browser security due to the ports being different between the local web server and the router stats web server.

So it could probably work if that page was embedded in one of the routers, that way the ports would match.

Seems like the best firmware for vectoring is the one Openreach tested as working with it.

@Alex We discussed the problem of getting a local web page to work on an ipad in another thread some time ago for this reason. Thank you for your ingenious solution and the work involved. My html is very rusty, havenít done any in 15 years.

Big thanks to siofjofj for this firmware for the VMG1312-B10A: https://www.dropbox.com/s/8hd7soax9m5tyqf/1312-B10A-17-jumbo-v2.bin.

This has the jumbo frames patch applied and also the A2pv6F039v2 DSL firmware. This was tested by Openreach as being compatible with vectoring.

I've been testing for just over 12 hours and no issues so far. Thanks again!

Got it. Thanks, will report back, will take a little while though.



On an unrelated matter: Firmware enhancement request: could the graphical stats server code reject various eg negative numbers present in the raw data when they are nonsense? Iíve noticed very very rare spikes in the CRCs graph going to approx ~-32030 and in the FECs graph to ~-4 850 000 which I would put down to Broadcom software weirdness. They are just a nuisance as they push the graph scaling into a highly zoomed-out weird state.

I have saved all the data from the johnson easy-stats server - attached.

Could someone remind me as Iíve forgotten: what are the time intervals used for the counts in eg the CRC events graphs ? That is y-axis = CRC events per what? Did say in an earlier post somewhere.

I assume you are refering to displays within DSLStats, if so, as B*cat has said the "Y" axis is per min..

Note, the DSLStats "Averages" page displays CRC, FEC, HEC, ES, SES errors per hour, daily rates.

@tiffy No, to the johnson easy-stats graphs that are published by the second http server in the modem with custom firmware. As in the title of this thread. I should have said, sorry.

@Burakkucat - to which software were you referring, my friend ? How did you interpret my confusing post?

Hmm . . . I based my response on the tingles felt in the whiskers whilst thinking about the last time you asked about sampling rates. So I could just be caterwauling nonsense.  :-[

Itís in an old thread somewhere, but I donít know what to search for.
