[NCLUG] configuring ssh on Ubuntu

After many years of Fedora (beginning with RH4 in 97 or so, then KRUD
until 2003) I decided to dip my toe into the Ubuntu 6.10 waters.

And it's wonderful, I love it, the software updater seems to work a
little better out of box than FC6's (YMMV) and brown is a nice change
from blue.

But.

How the devil do I configure ssh so it works? By "works" I mean...

When this box was running FC6 I could ssh to my emac in the next room.
None of the network infrastructure has changed. Just what OS this
machine runs.

Now the network here works in general: I can surf the web, get mail, etc.

But when I try to ssh to the emac I get a message "connection refused"
as if the emac were blowing me off. But I don't think that's a true
statement. On the other hand, when I ssh from the emac to the Ubuntu
machine here, that works.

I clobbered all the relevant entries in my .ssh/known-hosts and
authorized_keys2 files on both machines.

There's nothing relevant in the /etc/hosts_(deny|allow) files.

I read <https://help.ubuntu.com/community/SSHHowto> and even
<https://help.ubuntu.com/community/AdvancedOpenSSH> but if there's
help for me there, I missed it.

Any ideas?
