When you trying to connect SSH login in your terminal the connection (response) time is very slow, need to update few thing in your ssh configuration file.

Solution:

Open your terminal as root permission
 
Open your sshd_config file using any editor (vim, vi)

vim /etc/ssh/sshd_config

Uncommand the first two lines and add "UseDNS no"


GSSAPIAuthentication no

GSSAPICleanupCredentials yes

UseDNS no

Fianlly, restart your ssh service,
 
# service ssh restart


ssh stop/waiting

ssh start/running, process 4675
