This article is about how to modify the SSH service port in linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Modify the configuration file first

Vi / etc/ssh/sshd_config

Find the section # Port 22, where the logo uses port 22 by default, which is modified as follows:

Port 22 Port 50000 and then save exit

The service restart takes effect.

/ etc/init.d/sshd restart

This makes SSH ports 22 and 50000 available at the same time.

2. Configure the access policy of the firewall:

Vi / etc/sysconfig/iptables

Enable port 50000.

Firewall restart:

/ etc/init.d/iptables restart

Now use the ssh tool to connect to port 50000 to test for success. If the connection is successful, edit the settings of sshd_config again and delete the Port22 inside.
