SSH Connection

["Rudik A.A." <rudik sgn com>]

Hello All,

I am facing problem to login to my RH 7.1 server  by SSH. After typing
passwd for root it gets "Connection closed"
I mast say that it was working good and today we could not login not
only as root, but any other users also can not login by ssh.
And also telnet is disabled.

Any idias ?

Thanks in advance.
