Factory reset – locked me out

[Lucian Corduneanu]

Hi guys,

I recently upgraded to 5.1.2 from web UI. I performed a factory reset (first from web UI, then from button, holding more than 30 sec).

Now I’m locked out of the system. It seems like the default credentials are not working anymore. I tried:

1. admin / admin
2. admin / root
3. root / admin
4. mtadm / root
5. mtcdt / root

Please help!

EDIT> I’m trying to connect via USB debug cable. Seems like the network interfaces are not well configured, and I don’t have access to web UI.

I read the following pages:

http://www.multitech.net/developer/software/mlinux/getting-started-with-conduit-mlinux/

http://www.multitech.net/developer/software/aep/reset-button-behavior-for-aep/

Hmm, this is interesting.

A Hard Reset (or Factory Default) will force 5.0.1 firmware into Commissioning
Mode to create a new Administrative Username and Password.

Eliminate Default Username and Password. User prompted to set up a Username and secure Password upon Factory Default/Hard Reset, Commissioning Mode.

How to create a user in Commissioning mode please?

Alright. I figured it out.

There is no user at first, only through Web UI, you can create one.

I properly connected and configured the network interfaces so that the default 192.168.2.1 – address of the Conduit AEP is used, only after that I was able to first create the user, then login.

Thanks for the topic and follow-up.

[Lucian Corduneanu]

Well, it remains one question though:

How can I have ssh access with root privileges?

Seems like the users I created through the commissioning mode, is not among sudoers.

Any help is appreciated. Thanks 🙂

[Jason Reiss]

The user created through commissioning mode should be able to elevate to sudo.

Try after login through ssh.
$ sudo -s

[Lucian Corduneanu]

Well, I tried many things.

admin@mtcdt:~$ sudo -s
Password:
admin is not in the sudoers file.  This incident will be reported.

However, I think it’s worth mentioning, right before the first factory reset I edited with sudo visudo and maybe I messed up something there, in my attempt to gain root access.

Isn’t the factory reset, fixing this as well?
If not, is there a way for me to gain root access somehow from Web UI?

Thank you.

[Lucian Corduneanu]

Damn it, yeah it could be that this is the case.
I remember I commented out a line and enable another. Don’t know which, but I think I enabled the:

# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL

[Jason Reiss]

You will need to do the firmware upgrade with 5.1.2 to restore the suders file. Factory reset only affects the config partition.

[Lucian Corduneanu]

Excellent! Thank you.

That was enough to restore it. I now have root access with sudo -s.

Thanks for spotting this, Lucian. I struggled to diagnose this because the factory reset AEP took on my router’s IP address (192.168.2.1) so http didn’t work. Resorting to USB debugging I then struggled to find any username/password combination that worked, so thought I’d lost my mind. Thanks for saving the AEP from the bin.

Also worth mentioning to save 20 minutes of messing about. The PATH is pretty useless, and ifconfig is here:

/sbin/ifconfig
