How to change SSH Port

In order to change your ssh port you need to “allow” it in SELinux:
1.Install package that provides “semanage” comamand:

CODE: SELECT ALL

yum install policycoreutils-python

2.List all ports allowed for ssh daemon:

CODE: SELECT ALL

semanage port -l | grep ssh

3.As you haven’t modified anything you shouldn’t see your port.
Now add your port:

CODE: SELECT ALL

semanage port -a -t ssh_port_t -p tcp your_port_number

If you are using a port that is well-known for another program you should use:

CODE: SELECT ALL

semanage port -m -t ssh_port_t -p tcp well_known_port

4.Verify it’s allowed now:

CODE: SELECT ALL

semanage port -l | grep ssh

5.Edit your sshd config to listen on that port (Listen 443 for example).Note that ssh supports listening on multiple ports:

CODE: SELECT ALL

vi /etc/ssh/sshd_config

Find this line
```
#Port 22
```
Change to your chosen port, and remove the comment ( # sign )
```
Port 9999
```
Restart the SSH service.
```
service sshd reload
```
Now we must allow incoming data in the new port. Open your WHM >> Plugins >> CSF.
Click “Firewall Configuration” button.
Add your new port in “TCP_IN” and “TCP_OUT”.
Click “Change” button in the bottom of the page.
You will be asked to restart CSF & LFD. Do it.
It’s done
