SSH issue SSH not allow to login For this following Possible issue


1. One of the possibility is your firewall rules are blocking ssh connections

Like Firewall On – Disable firwall or allow the SSH connection through the firewall

#Service iptables stop


2. Allow only SSH connection

Allow only the incomming SSH connection to the linux box from anywhere

#iptables –A INPUT –I eth0 –p tcp –dport 22 –j ACCEPT

#cd /root/.ssh

#vi know_hosts

Note- delete everything on that file

#service sshd restart
