[SOLVED] Cant ssh for a user

kirtikjr · 08-04-2011, 09:13 AM

This is the entry when I tail /var/log/secure when I ssh for user "nightly"...

Code:

Aug  4 03:19:48 itanium2 sshd[10791]: Illegal user nightly from ::ffff:10.91.220.35

Aug  4 03:20:10 itanium2 sshd[10791]: Failed password for illegal user nightly from ::ffff:10.91.220.35 port 32862 ssh2

What could be the reason, plz suggest.

and password is correct, works when I telnet, just ssh fails.

there is a local user for the host with which I can ssh to the system but not with nightly. nightly is not in /etc/passwd

It looks like using ipv6, and I take that the user "nightly" is not available in your system. Check "getent passwd nightly".

I guess nightly uses LDAP or NIS to login. and getent passwd nightly shows the same result as a local user

Please post output from:

Code:

$ id nightly

Code:

$ grep 'nightly' /etc/passwd

Code:

# egrep -i 'allow|deny' /etc/ssh/sshd_config

actually nightly was an NIS user..
and the IP settings of the present host was changed.
So the keys got messy.
I disabled the PubkeyAuthentication option in /etc/ssh/sshd_config
Now I can login, but i need to regenrate the keys
