Okay,

I've been in this group and others for a while trying to figure this problem
out. My customer is telling me to make it work or they want their NT Server
back!

I have a SQUID proxy/qmail Email/Samba PDC Server running on RHL 7.3.
Everything works fine except for a connection to port 4000 which worked on
their NT box. There is a specific website that loads a PowerTerm applet for
the users to login to a HP-UX system. The PowerTerm program needs to send
its authentication information over port 4000. When this is attempted it
claims the host (www.specific-site.com) cannot be found. I've been on the
phone with this site's TS and they say that port 4000 has to be open for TCP
communication. Port 4000 is in the Safe_ports ACL list in squid.conf. I
don't see any references to this port in my tcpdump logs, or squid logs. I
am attempting this connection without a firewall (iptables) script running.
I have read everything I can find on tcpserver, xinetd, and Linux
Administration. Everything I'm reading tells me that this communication
should be allowed and should work, but it doesn't. Running "nmap localhost"
shows me that only ports 22, 25, 110, and 3128 are open. How do I get
communication to travel through this port? Does port 4000 have to be always
open like 22, 25, 110, and 3128? If so, what server program needs to
monitor it? What am I NOT doing right?

I've been given one week to figure this out or I will have to revert back to
(gulp) their NT box for proxy. Please help me figure out what needs to be
done. Let me know what additional info you need.

Thanks in advance
