hey friends,
I am able to make multiple instances of sshd with different user settings.
created multiple binaries of sshd under /usr/sbin that is sshd1 sshd2
copied /etc/pam.d/sshd to sshd1, sshd2 etc.
under /etc/rc.d/rc.local added these lines
/usr/sbin/sshd1 -f /etc/ssh/sshd_config1
/usr/sbin/sshd2 -f /etc/ssh/sshd_config2
in sshd_config1 & sshd_config2 modified settings for the users.
only problem is that I am not able to make a service for sshd1 & sshd2.

When I try to start sshd1 it shows these errors in the logs
Jun 1 14:59:15 test1 sshd1[4071]: error: Bind to port 22 on
192.168.1.125 failed: Address already in use.
Jun 1 14:59:15 test1 sshd1[4071]: fatal: Cannot bind any address.
I hope somebody can guide how to write the service script for sshd1.
Thanks & Regards
