I've tried this and it works, but please don't accept it as a perfect or
very secure solution:

Tested on RH 9.0

1. cp /etc/ssh/sshd_config /etc/ssh/sshd_config2
2. cp /etc/init.d/sshd /etc/init.d/sshd2
3. chkconfig --levels 345 sshd2 on

(Note here you can also symlink the correct runlevel scripts to
/etc/init.d/sshd2 to start it at run time

4. Edit /etc/ssh/sshd_config2 to listen to a different port.

Port 81

5. Edit /etc/init.d/sshd2 to include the following lines

# Some functions to make the below more readable
KEYGEN=/usr/bin/ssh-keygen
SSHD=/usr/sbin/sshd
RSA1_KEY=/etc/ssh/ssh_host_key
RSA_KEY=/etc/ssh/ssh_host_rsa_key
DSA_KEY=/etc/ssh/ssh_host_dsa_key
PID_FILE=/var/run/sshd.pid
OPTIONS='-f /etc/ssh/sshd_config2'

I only had to add the bottom line.

6. Start the second SSH daemon

/etc/init.d/sshd2 start

7. Test it by ssh'ing into your new daemon

ssh -p 81 simon at wt-linux-01

8. Sit back with satified grin and treat yourself to a cup of coffee as
mentioned on todays mailing list.

Hope that works for you.
