SSH listening funny...

[Duane Morin]

Traditionally I've run ssh on port 23 (for historical reasons).  Last 
month I patched ssh during that whole debacle.

Today I had a power outage. When I rebooted I discovered that ssh is 
running on port 22 again.  I thought "Oh, when I patched I must have 
gone back to a default config or something."  But /etc/ssh/sshd_config 
clearly says to listen on port 23.

So I have to assume that the sshd I'm running is not reading that file?
But where else might it be getting the info?
