Unable to SSH Linux Server CentOS 6.x
« on: January 30, 2016, 05:29:04 PM »
Hi All,

Couple of days before when trying to SSH a linux server, it was not allowing me to login. It kept on processing without any errors. However, further checking the verbose option with command below.

Quote
ssh -v root@xx.xx.xx.xx -p 22

I managed to poll the errors. The error was

Quote
debug1: Unspecified GSS failure.  Minor code may provide more information
Cannot determine realm for numeric host address

To fix the above error, I had to open the SSH config file /etc/ssh/sshd_config & find for GSSAPIAuthentication. Set GSSAPIAuthentication to no and restart SSH service.

You will be able to access the server via SSH now.
