backuppc rsync backups on different ports

I have installed backuppc and have configured the backup server@  ssh port for it is 22

i have configured client machine@  ssh port for it is 22

what i want to do is have backup pc use rsync on a different port.  i want the backup server to use ssh port 100
and the client machine to use ssh port 200

I have looked at rsyncd in the man pages and from my understanding it will leave a password file on the machine, i dont think i want that.

right now with ssh port at 22 all backups are working fine.  but i want to change the ports to what i have put above.

No probs! (but why?)

If you want to use another port with ssh all you need to do is edit the /etc/ssh/sshd_config and add a 'Port' statement for each port you want to listen to.

In your example that would be

Port 100
Port 200

and then restart the sshd (service ssh restart)

But there are no real good reasons for this action (IMO).

I am sorry i should have been more clean, what i want to do is to have backuppc server at location "A" connect to client machine at location "B" on port 200.  both locations are behind firewalls with rules applied to only allow traffic from each other.  i am planning that at location "B" i will be backing up multiple computers so i will have different SSH ports for each computer.

But why a different port for each computer?

It will not help security at all!
