Authentication issues trying to log onto a box as a standard user, and cron jobs...
Hi
I am trying to connect to a squeeze VM as a standard user using ssh
keys, whenever I try to ssh into the box the connection is closed by
the VM:
ram@g5:~$ ssh -v lal-squeeze

ram@g5:~$
I can't find anything in the logs regarding this connect.
I can log onto the box as root.
Next when I su to a user account I receive the following:
root@lal-squeeze:~# su -l laltest
su: Authentication failure
(Ignored)
laltest@lal-squeeze:~$
so something is clearly wrong and I imagine this authentication issue
may be related to the inability to log on as a user.
Also I have a cron job scheduled, via crontab, to run at 21:01
everyday. It fails to run and the only reference to this I can find in
the logs is the following:
Apr 8 21:01:01 lal-squeeze CRON[14107]: Authentication failure
So I imagine that this is a different manifestation of the same problem.
Any recommendations on how to debug this issue?
Cheers
Adam
