John,

I really think the problem may be with iptables. We've eliminated just
about everything else. H³owever, there is no ma pagel for netconfig, and
when I tried running it, I wasn't sure what to do. Really, all I need is
to let one IP address use ssh. There is a man mage for iptables, but it
looks so complicated that I wouldn't want to mess with it unless I knew
exactly what I was doing.

Thanks,
John
