You're on the right path for what you want to do.  I don't recommend 
having ssh so open, even from the inside, but that _is_ your decision.
The error is probably a red-herring.  Start both ssh daemons then check 
the lstening ports:
netstat -atnp | grep ssh

Chances are all is fine and the issue is that you have ipv6 and ipv4 
enabled (fc4 default) and ssh is discovering a conflict opening a socket 
to listen at the designated port on the ipv6 superset of your address, 
and then another socket to listen at the designated port on the ipv4 
address.

If you don't actually need ipv6 add the following to /etc/modprobe.conf 
and then reboot:
alias net-pf-10 off
