I’ve edited /etc/ssh/sshd_config to change the port number:

Port 1255

However, I’m getting an error as follows:

sshd[26792]: error: Bind to port 1255 on 192.168.1.100 failed: Permission denied

How do I change default OpenSSH port number from 22 to 1255 under RedHat Enterprise Linux server version 6 and SELinux?

I‘m trying to use semanage command to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources under RHEL 6 server. But, I’m not able to find out this command and/or package name. How do I install semanage command under RedHat Enterprise Linux?
