Kobo Libra 2 - telnet enabled?

Parsons · 07-24-2024, 08:41 PM

I have a Kobo Libra 2 (firmware 4.38.23038). I thought that I could enable telnet on it by using devmodeon but that doesn't seem to work. When devmodeon is enabled, I can see the additional menu items, but I can't open a telnet session as the connection is refused.

I can open telnet sessions to other devices on the network but not to the ip of the Kobo.

Am I missing something simple here, or must I install nicklemenu to enable telnet on the Kobo Libra 2?

You can only enable telnet through NickelMenu in the latest firmware, and the login credentials are now admin/admin.

Thanks. That was very helpful.

I have installed nicklemenu and can now open a telnet session. I wanted to install tailscale which I now have up and running but I have realised that I should have updated the version number first. When I try to run the uninstall tailscale command I get permission refused.

I'm a linux novice so I'm clearly doing something wrong. Telnet appears to log me in as root but maybe something more is needed to execute a command?

I used ./ uninstall-tailscale.sh but get permission refused which seems odd as I successfully ran the install command that way?

Any idea what I'm doing wrong?

Not sure but you could try running su - or su root before the uninstall script.

Sudo doesn't appear to be enabled on the kobo?

Linux noob here but should there be a file uninstall-tailscale.sh in the tailscale directory?

Also tried su root ./ uninstall-tailscale.sh which returns file not found

su - or su root on one line than the uninstall script on the next line. BTW, there should be NO space between the ./ and uninstall.

./uninstall-tailscale.sh from the directory it lives in which should be the directory from which you installed tailscale using the install script.

Yes, it's failing because you have a space between ./ and the script name, so it's not even trying to execute the script, as your syntax is invalid.

Thanks for the help! I tried it with and without a space but the real problem was that I wasn't in the right directory. The install directory is somewhere else.

The install/uninstall instructions on github are very clear - if you are a linux user which I am not. Total noob error!
