As a follow-up to my previous post about adding
sshd instances on CentOS 5 & 6, here’s a script that does the same on RHEL/CentOS 7.
The script still checks for
iptables and if it is active, will add a rule to accept connections. Why not
firewalld, you ask? Because it’s an abomination and, if you’re using it, you should be ashamed of yourself.
del script will prompt you for the
sshd instance name to disable and delete.
