How to modify the ssh port of Linux server?

The steps to put the ssh server software configuration file in the /etc/ssh/ directory are as follows

1. Enter this directory.

# cd /etc/ssh

2. Edit its configuration file sshd_config.

# vim sshd_config

I found a line #Port 22 in it. This line is very forward, almost not far from the beginning of the document. Remove the # sign from this line.

Then add the port number you want to change, and I'll change it to 2343 here.

Port 2343

4. Restart the sshd service

# servicesshd restart

5. Change the ssh port to 2343.

Pay attention to changing the port number when connecting ssh.

Such as ssh192.168.11.122343.
