You can run ssh on multiple pots. Default port is 22, if you want to enable additional port say 49002,

just edit /etc/ssh/sshd_config with your favorite editor, and find the line that says

Port 22

add another one below it so it looks like this

Port 22
Port 49002

And restart sshd

root@ [~]#/etc/init.d/sshd restart

verify that it’s listening

[root@sever~]# netstat -anp | grep ssh
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 21085/sshd
tcp 0 0 0.0.0.0:446 0.0.0.0:* LISTEN 21085/sshd
tcp 0 0 :::22 :::* LISTEN 21085/sshd
tcp 0 0 :::446 :::* LISTEN 21085
