Just to add something to this discussion. Today, I've just noticed that ssh 
has become disabled on two separate machines, one at home, and one at my 
office. Both are FC4 and are kept up to date with latest patches. I haven't 
really dived in, yet, except to look at the ssh config files, where there 
didn't seem to be anything amiss. So far, I've tried applying my firewall 
rules from fwbuilder to both machines, and both give back ssh errors. I then 
tried a simple log on via ssh to the local machine at work, and it failed. I 
just tried to log in to my office machine from home, and it just stalls. I 
don't know when this stopped working, but the fact that it's happenning on 
two machines widely separate, makes me wonder if some recent update broke 
things...
