I've put the 9980 150507 firmware on my 8970, I expect it would work, but I am not really using it currently, it's sat on a shelf and occasionally switched on and used as a network switch.

Code: [Select]
# /firmware/dsl_cpe_pipe.sh vig
nReturn=0 DSL_DriverVersionApi=4.16.6-pd1pa1 DSL_ChipSetFWVersion=5.7.1.8.0.1 DSL_ChipSetHWVersion=Unknown DSL_ChipSetType=Lantiq-VRX200 DSL_DriverVersionMeiBsp=1.4.4 nHybrid=1

~ # /firmware/dsl_cpe_pipe.sh locs 0 -10
nReturn=20

~ # /firmware/dsl_cpe_pipe.sh locs 1 1
nReturn=-11
~ # /firmware/dsl_cpe_pipe.sh locg 0
nReturn=0 nConfigValue=-10

~ # /firmware/dsl_cpe_pipe.sh locg 1
nReturn=-11

locs / locg options 0 and 4 appear to be valid (4 is ADSL2/2+ enhanced US framing, enabled by default), options 1, 2 and 3 give that nReturn=-11, negative return values indicate an error.

JUst bought a tp-link w9970 modem/router with a broadcom chipset.

Using ejs' StatPOSTer-20150824.jar I can get (same as other tp-link routers) some stats but I cannot decrypt the config.bin configuration file from the GUI to try the addition to the config file as described here http://forum.kitz.co.uk/index.php/topic,14377.msg287247.html#msg287247

I presume the key has changed from this method http://teknoraver.net/software/hacks/tplink/

Any ideas how to find the 8 byte key for this model and firmware?

The bytes of the key used to encrypt the config file can be found by disassembling the cli binary. Of course it's much easier to find them if you already know what they are. The key appears to be the same for the TD-W9970.

The StatPOSTer program should save the decrypted file, but you will not be able to edit the file, because it is compressed. If you examine the decrypted file in a hex editor, you might see a few readable parts of the config file near the start of the file, but there are less readable parts further down the file. I do not know how to decompress the data, nor how to compress it again.

It might be possible to adapt the strategy used with the TD-W9980, but the first problem is that I don't have a blank editable xml config for the 9970, and the second problem is that there may have been some slight changes to the file format, the MD5 checksum at the start might be for the compressed data, rather than the uncompressed data like it is for the older models.

In summary, it might be possible to work out how to do it, but it requires some original research by someone who has the device and is willing to do a lot of experimenting with it, while it's not connected to the phone line of course, because it may require a lot of rebooting. It's also possible that if you upload a config file with somehow bad contents, the device may accept it, load it, and reboot, but the device may not function and requires pressing the factory reset button. The minimum tools needed would be a hex editor, an md5sum program, and some program like the openssl command that can do the encryption (can't use StatPOSTer because it adds or removes the MD5 checksum automatically).

If you send me a sample config file (with no personal data in - factory reset the 9970 first), I could look at it, but even if I could figure out how to adapt the method used with the 9980, which there is no guarantee I could do, or even that the strategy used with the 9980 can be applied, there would still be the problem of the blank editable config file needed.

I know there's a default_config.xml file in the firmware, but that's also encrypted on newer models, and I haven't found how to decrypt it yet, and in any case, that default_config.xml file is nothing like the config saved by the device, so even if someone finds the key and how to decrypt it, it's doubtful it could be used anyway.

Thanks ejs...i will disconnect sometime this week, and use another modem; i will then reset and post a default config on a new thread.

I have now reset and uploaded the default conf.bin.

Update from ejs

The latest version of the StatPOSTer program is 20160306
http://ejs1920.users.sourceforge.net/StatPOSTer-20160306.jar

The new version has a choice of devices to target when encrypting a config file:
TD-W8970v1
TD-W9970 (as tested here)
TD-W9980
VR900 (untested)

I'm trying to get some basic stats (including serial number) from my TD-W9970 and struggling, so I'm hoping it's something silly I'm doing that can be solved easily.

I'm using the following to try and retrieve the same info as the StatPOSTer java app, as I want to do this via shell scripts so using curl is a must. The command I'm using is:

Code: [Select]
curl -X POST -d '[IGD_DEV_INFO#0,0,0,0,0,0#0,0,0,0,0,0]0,0' --referer http://192.168.1.1/ --header "Cookie: Authorization=Basic `echo -n admin:admin | base64`" --header "Content-Type: text/plain; charset=UTF-8" "http://192.168.1.1/cgi?1&1"
But this constantly just returns "[error]71111"

I've tried several ways of providing the post data/binary, including it in a file and not, but none work, they all return the same. Using the statposter.jar it works fine, I can query "IGD_DEV_INFO" it returns the info I'm looking for.
Wireshark shows the post payload as:

Code: [Select]
[IGD_DEV_INFO#0,0,0,0,0,0#0,0,0,0,0,0]0,0\r\n
Which I've tried in the post data and data file without luck, can anyone spot the stupid mistake I'm making please?

Thanks!
Andy

The URL is incorrect but that doesn't actually matter, and the -X POST is unnecessary because curl automatically does a POST request if you specify -d.

The main trouble is with putting in the carriage return and new line characters into the data.

This should work:

Code: [Select]
curl -d $'[IGD_DEV_INFO#0,0,0,0,0,0#0,0,0,0,0,0]0,0\r\n' --referer http://192.168.1.1/ --header "Cookie: Authorization=Basic `echo -n admin:admin | base64`" --header "Content-Type: text/plain; charset=UTF-8" "http://192.168.1.1/cgi?1"
I abandoned doing anything with the TP-Link HTTP POST interface in favour of gaining proper telnet access.

Ahh! Thank you so much ejs, something so silly I'd missed it :-)

Working great now, thank you.

Is there any chance of StatPOSTer program to work with TP Link VR600 please?

getting error:

2017.02.05 20:10:39 xDSL Stats (1st,Auto):
java.io.IOException: Server returned HTTP response code: 500 for URL: http://192.168.1.1/cgi?1&5

It often gives that error the first time, just try again.

Really though, the stats available using that method are limited and it's fairly unreliable, so that aspect of the program is deprecated. The program's main useful function now is for generating config files for gaining proper shell access. The CPU architecture of the VR600 is the same as the 9970, so the config file formatting might be the same.

Does the VR600 require you to enter a user name when logging in?  :-\

If no, just set the string in the "User name" box to null and try again.
