Or maybe some kind of DNS issue is going on.

Subject: [LARTC] long delays with NNTP after switching T1 to other
servcie provider


After moving a Linux server serving as a wireless gateway/router to another
ISP,
I noticed a problem with NNTP.  When attempting to communicate NNTP through
the
Linux server, there are long delays that often result in timeouts.  For
example,
when using the newsreader pan, I get the following errors in the log file,
in
reverse chronological order:

Connect Failure
NNTP handshake failed: Error reading from socket.
Handshake failed: Error reading from socket.
NNTP handshake failed: Error reading from socket.
Timed out waiting to read from the server.


The Linux server is fed with a T1 from a different source.  Before changing
over, there was no problem with NNTP.  The only other difference that would
seem
to matter is the reconfiguration of the server.  I only took some services
off
line (qmail for example) and reconfigured the routing.  All other traffic
through the server works well, with the exception of dhcp which I haven't
resolved yet.

I suspect a QoS control issue from upstream.  Is it possible that NNTP
requests
are sitting in a queue somewhere waiting for a the "right" time to dequeue?
If
so, would there be something I could do with the TOS that might help?  Or Am
I
on the wrong track?

TIA,
David Koski
