Answer / lokesh bisht
First check basics
1 user is easily getting access without any interruption.
That's mean server is up and SSH is running on the server
perfect.
First check client side.
Is he getting login prompt if yes..issue can be wrong
username and password.
If no
First check network cable and ip address..and possible try
to login other server from that machine.
Server side.
First check Logs in /var/log/secure...you will be get break
through point for troubleshoot.
Check user is available on server with proper configuration
with chage, files etc.
If still user facing issue with login...so change password
then try it.
As per my personal experience, user never told you that i
forget the password, they will try to sit on your shoulder..
