ssh keeps throwing me out

Question

I can't access my client's server over ssh even from the console. It looks like it let me in and then trow me out. Here is my session with the verbose option (I've changed my IP with 192.168.0.1):

debug1: Next authentication method: password
root@192.168.0.1's password: 
debug1: Authentication succeeded (password).
Authenticated to 192.168.0.1 ([192.168.0.1]:22).

From a recovery console I mounted my disk and made sure firewall is disabled. Can anyone help me on this? Also, I don't understand what the ipaliases message above means. Thank you.

It looks like the /etc/profile or root's .bashrc or .bash_profile has an ipaliases command in it, which isn't being called properly (hence the Usage: ... line). Without seeing those files, it's hard to say for sure, but that would be where I would look first.

If you can, log on as another (non-privileged) user, try to run su - to gain root privileges and have a look at the above files for any ipaliases commands.
