Telnet Login - admin credentials fail

[kobotouch2711]

Dear all,
I managed to get my Kobo basically running again.
However, with telnet activated in NickelMenu, I can yet connect to my kobo, but the credentials "admin"/admin and "kobo"/kobo both fail. (Login incorrect)
Previously, admin/admin has always been working fine.
Any hints, what I am doing wrong? How could I change the credentials?

Is there also a way to connect via SERIAL Com port? Might be more stable...

Thanks for any hints!

If you have updated your firmware, you may no longer have telnet capability. However, you do get SSH in the newer firmware. To check if you have SSH capability, look for a file named ssh-disabled in the .kobo directory. To enable SSH, rename that file to ssh-enabled and you should now be able to do an SSH connection with root as the username. The first time, you will be prompted to enter the password. I've quoted the contents of the ssh-disabled file below:

To enable ssh:
- Rename this file to ssh-enabled
- Reboot the device
- Connect via: ssh root@<device_ip>

I have renamed the ssh-disabled to ssh-enabled, rebooted, but still i get

--> ssh root@192.168.178.53
ssh: connect to host 192.168.178.53 port 22: Connection refused

Any further clues?

Also any clue, if I could get a serial connection via USB, to have a backup in case my WIFI on the devices crashes again. This might help debugging.

As long as I have WiFi enabled (I tend to use the Force WiFi ON in the Developer Options or as an option in NickelMenu), SSH works for me. Of course, this generally ends up with me noticing my battery dropping because I forgot to turn Force WiFi ON off.

I've added the 2 NM items below.

menu_item : main : Toggle SSH            : cmd_output     : 500: quiet: test -e /mnt/onboard/.kobo/ssh-disabled
      chain_failure  : skip              : 3
      chain_success  : cmd_spawn         : quiet  : mv /mnt/onboard/.kobo/ssh-disabled /mnt/onboard/.kobo/ssh-enabled
      chain_success  : dbg_toast         : SSH Enabled
      chain_always   : skip              : 2
      chain_failure  : cmd_spawn         : quiet  : mv /mnt/onboard/.kobo/ssh-enabled /mnt/onboard/.kobo/ssh-disabled
      chain_success  : dbg_toast         : SSH Disabled
      chain_always   :  power            : reboot

menu_item : main    : Force WiFi on      : nickel_setting  : toggle: force_wifi
     chain_success  : nickel_wifi        : autoconnect

Note that the display items for the SSH state are pretty much useless since they are not displayed long enough to be useful.

I am running 4.38.23429, but no success

Further feedback highly appreciated.

Dear all, I try to open up again this topic.
Despite following the above mentioned steps and having a file ssh-enabled, my ssh attempt always fails with connection refused (port 22).
ssh root@192.168.178.101

The IP is the kobo device's ip and connection is established.

Is there anything with the port to be changed?

Any other way to access the console? Can telnet be reactivated? This has been working reliably in the past.
By the way: telnet seems to be open/running, as I can connect to it, but kobo login/password "admin"/"admin" is refused.

Does your file ssh-enabled perhaps have some silly file extension that you're not seeing under Windows?

It's been years since I've played around with ssh/telnet on Kobo, so I may be missing some new developments. But in general it should be possible to install an /etc/passwd with a known root password hash with the KoboRoot.tgz mechanism. If that's what's keeping you from connecting via telnet.
