Did you remove all mentions of port 22 in the alternate configurations (in Port and ListenAddress entries in their config files). Only one process can be listening per port.
The entries are like this sshd_config Port 22 ListenAddress 192.168.1.125 sshd_config1 Port 3452 ListenAddress 192.168.1.125 sshd_config2 Port 3453 ListenAddress 192.168.1.125 Thanks & Regards Ankush Grove
