Duplicate ssh session

If you are using secureCRT or ssh client, you may discovered that duplicate a ssh session you do not need to login again. That is convenient and fast!
I can do that with ssh command by just adding 2 lines shown as bellow into /etc/ssh/ssh_config
(Thanks to Geek00L)
ControlMaster auto
ControlPath ~/.ssh/socket-%r@%h:%p
You have to login for the first time, the first session will initiate a Control Master by creating a file at ~/.ssh indicate the login name, host and port. After that you can duplicate a ssh session by just execute a ssh command the same way you did for the first login, but this time password is not required.
Cool isn’t it?

I tried on your solution. It works for OpenSSH 4.3 (CentOS 5) but it doesn’t work for OpenSSH 3.6.1 (RHEL 3).

You are right, OpenSSH 3.6.1 doesn’t have
ControlMaster autoOnly yes or not, it happens to RHEL 4 too.

Only OpenSSH 4.0 above have ControlMaster support
