Hi, 1) Are you trying to connect as "root"? If so, you should absolutely not do this. Always use a regular user account and su or sudo afterwards. 2) Are you using a different default shell than /bin/bash? 3) Are you using some kind of central authentication (LDAP, AD) and/or a non-local /home directory, like, say, a NFS mount? 4) What happens when you try to log in using a newly created user with an "empty" home directory on the server? 5) Is there anything non-standard in /etc/profile.d/* /etc/profile /etc/bash.bashrc ~/.profile ~/.bashrc (For example, /root/.profile contains "mesg n" at its end, by default, while regular user accounts don't have that in their ~/.profile. This causes error messages - though usually different ones than the one you reported - when trying to connect as root, and results in a failed connection. Something similar might be going on here.)
