[SOLVED] Cannot login via SSH

[labsy]

Hi,

any idea why I cannot login via SSH to my 23.7 version anymore? I am using Putty, terminal window opens, asks for login, I enter my username, then prompts for password, and as soon as I enter password, Putty terminal window closes. I can Putty to all other servers and devices, so I guess Putty is OK.

Logs in OPNSense web consile show like I am logged in, but I am not:

2023-09-26T18:12:11 Informational sshd Accepted keyboard-interactive/pam for myusername from 123.212.63.25 port 52121 ssh2
2023-09-26T18:12:11 Notice audit user myusername authenticated successfully for sshd [using OPNsense\Auth\Services\System + OPNsense\Auth\Local]

Lol...solution:
somwhow under my username I've had login shell set to /sbin/nologin, which is a polite refusal of login. Changed this to /bin/sh and I am in. :)

I've tried using nano vim and usermod to add a shell back to my account via root.   How did you add a shell to yours?

As of recently I too cannot login via SSH any longer. It started after the last two Opnsense updates.
I tried two different accounts that previously worked and are members of the admin group.
How do I fix this?

Using the UI, can you check that the user has an adequate shell assigned ie. not /sbin/nologin ?
