[vox-tech] Re: [vox] internal access to jabberd by name

(Moved to tech because it's about to get messy...)

I'm using NAT.  Slackware 4 on a P120 w/ 2.2.x kernel.

The jabberd server is running on a box behind the P120, so I portfw back to 
# jabberd server
ipchains -A forward -p tcp -s <INET_IP>/32 5222 -j DENY
ipmasqadm portfw -d -P tcp -L <INET_IP> 5222 -R 5222
That let's everyone from the outside get to it.

On the windows box behind the P120, the domain name resolves to my ip, but 
because of how I set up ipchains and ipmasqadm, it doesn't accept the 
connection.  It comes in on the wrong interface side.

Well no matter, I'll just put it in my hosts file under Windows.  But QT3 has 
a bug where it doesn't read the hosts file.  (They don't use the windows 
gethostbyname(), because it blocks.  They didn't wanna require threads for 

I ended up hard-coding the IP of the internal host into Psi 
(psi.affinix.com), and passed the domain name in the XML to make jabber happy.
Mmm source code!

I should have just made a better jabberd portfw script, but where's the 
fun in that? :)
