Post Maximum tcp port for OPENSSH

Hi all,

I have RedHat 7.2 and RedHat 6.2 boxes. For the reason of security, I want to change the port from 22 to 60000. When I make this change on RedHat 7.2 boxes, it's OK; While doing the same thing on 6.2 boxes, I found the sshd service couldn't run. After many times of trying, I got the maximum sshd port, which is 40999.
I just wonder, whether this is really the common theory in RedHat 6.2? Since I don't find such kind of limitation in ssh manual.
