Re: squeeze, dns, fetchmail error

How to troubleshoot this error?  I've done hours of googling but can't
find anything that helps.

fetchmail: couldn't find canonical DNS name of pop-server.triad.rr.com
(pop-server.triad.rr.com): Name or service not known
fetchmail: Query status=11 (DNS)

If I replace "pop-server.triad.rr.com" with the IP in .fetchmailrc, then
fetchmail works fine, and very fast. ping and nslookup get the dns done
as expected.

Here is my ~/.fetchmailrc:

# pop-server.triad.rr.com
# IP is

poll pop-server.triad.rr.com  proto pop3  auth password
	user "hlawson"  password  "PASSWD"
	sslproto ssl23

Something very similar happens with emacs gnus in relation to its news
server.  This is a squeeze trial install. My regular Debian is lenny,
and it works fine.


Is all the DNS servers in the resolv.conf correctly reporing the name resolution ? If no can you remove all but one of the DNS entries in the
resolv.conf and check if fetchmail works !

 You can install strace and check what is exactly happening (you can see
the connect command and then who is replying that the DNS resoltion failed
etc., ... )

For some reason, squeeze puts the ethernet interface on eth0, while in
lenny it's eth1.
