Modifying the sshd port in Centos7

For security purposes, we often modify the SSH default port by default to 22.

First, get in the same way as CENTOS5/6. SSHD Service configuration file

1. Vi/etc/ssh/sshd_config

Find #port 22 get rid of # 22 change to what you want I changed to Port 2000 then save

2. Restart the SSHD service

Systemctl Restart Sshd.service

3.semanage port-a-t ssh_port_t-p TCP 3333

Add Port 2000 to SELinux

Systemctl status Sshd.service to view sshd service port Status

4. Turn off SELinux Services

Test telnet [IP] [port] on the remote host

SSH [email protected]-P 2000

[email protected] ' s password:

Enter a password to access
