Hi,

Been happily using DSL stats for a while with this router, however I have updated the firmware to the 5.13 version V5.13(AAXA.7)C0 which is the latest release.

Now none of the telnet commands work, instead of the busybox header once logged in i now just see ZySh> and none of the existing commands now work.

Any ideas other than going back firmware versions.

[skyeci]

I have seen the same problem on a vmg 3925. it was fine till upgrading with the latest firmware. In the end we rolled it back to an earlier version. busybox had disapperaed.. 

[shoey]

Yeah i think i will have to roll back as well.

[shoey]

I was running 5.11(AAXA.4)C0 which was Nov 16, and 5.13(AAXA.7)C0 is Dec 17 going to try 5.13(AAXA.5)C0 Jul 17

[burakkucat]

Very peculiar. 

I have a ZyXEL VMG1312-B10D and it is using the V5.13(AAXA.5)C0 firmware.

Before you attempt to roll-back, I will suggest that you perform a reset to factory defaults and power-cycle the device. Once re-booted, reconfigure it and do not re-load any backup configuration file.

I have a suspicion that the device has just got very confused, as all firmware prior to V5.13(AAXA.5)C0 had the ROM-D device as /dev/mtd3 (/dev/mtdblock3) but with the latest firmware, the ROM-D device has been moved to the next partition, /dev/mtd4 (/dev/mtdblock4).

Hi burakkucat,

I havn't rolled back did a factory reset, and am back online. However when i telnet to the router and login as admin i am still greated with the following screen.

VMG1312-B10D login: admin
Password:
ZySH>

And i still cant access any of the xdslctl info, is there something else i need to do, as my sync speed has improved with the latest firmware, but as i am about to upgrade to vdsl, i would still like to be using my PI to run dslstats.

[burakkucat]

I really don't know what is happening. Are you sure you have a VMG1312-B10D? (Sorry if that is a silly question but it had to be asked.)

I normally access my modem/router via ssh but for the following experiment I also enabled telnet access. This is what I see when I access the device as admin, supervisor and root firstly by ssh (port 22) and then by telnet (port 23) --

[Duo2 tmp]$ ssh admin@ap
admin@ap's password:

I'm familiar with the ZyXEL Shell and can invoke it from the command line --

[Duo2 tmp]$ ssh root@ap
root@ap's password:

Enter 'help' for a list of built-in commands.

I'm puzzled by what you are experiencing. 

[shoey]

I only have access to the admin user, i don't know the password for the supervisor or the root user.

That's defiantly the right router, it was fine when it was on the 5.11 versions of the firmware and i just upgraded to the latest. Is there a command to get out of zysh?

[burakkucat]

Is there a command to get out of zysh?

The documented command is "exit". You could also try using <Ctrl-D>.

[JamesK]

I have the same issue after upgrading to 5.13. A factory reset didn't change anything.

[JamesK]

Looking at the firmware documentation, there is a mention of a change to the CLI....

Modifications in V5.13(AAXA.7)b1
[Feature Modification]
1. [eITS #170100670] allow port forwarding rule to be from any WAN
2. [eITS #170300570] Enhance OPAL Privilege feature
3. [eITS #170600099] Add FTP in the SP Domain management services
4. Support CLI interface

[skyeci]

agreed. a friend's vmg3925 lost busybox on the latest firmware regardless of what we tried etc.. the only way to resolve it was to roll back.

[broadstairs]

This is beginning to look like ZyXEL are determined to lock down their routers in future so ordinary users are unable to mess around with them. I suspect all new routers will be the same. Not really sure why they need to do this, could it be that to get their routers approved by BT in future they need to do this?

exit just closes the terminal session, i did email zyxel the support guy was like "Really they have removed that" hes going to talk to the developers and get back to me.

[JamesK]

I've just looked on the Zyxel website again. There's 2 versions of the 5.13 firmware:

• 5.13(AAXA.7)C0 released on 25/12/17
• 5.13(AAXA.5)C0 released 20/7/17

The 'feature' to add the new CLI was included in the work for the AAXA.7 release (b1).

I've just loaded 5.13(AAXA.5)C0 and as expected busybox is still present. This would explain why people using "5.13" could be seeing differing results.

To me, if you were making a fundamental change like this it would be worthy of a whole new version number to avoid confusion. Clearly Zyxel don't think so!
