Subject:	squid DNS problem
Date:	Tue, 25 Jan 2005 14:51:35 +0300
MIME-Version:	1.0

cygwin squid cannot retrieve a single page because

   The following error was encountered:
   Unable to determine IP address from host name for www.cygwin.com
<www.cygwin.com> 

   The dnsserver returned:
   Server Failure: The name server was unable to process this query.

and error 503 (service unavailable) is logged to access.log

   1106653186.612    266 127.0.0.1 TCP_MISS/503 1200 GET
http://www.cygwin.com/ <http://www.cygwin.com/>  - NONE/- -


But DNS is up, at least DNS tests are passed when squid starts

   2005/01/25 14:17:50| Performing DNS Tests...
   2005/01/25 14:17:50| Successful DNS name lookup tests...
   2005/01/25 14:17:50| DNS Socket created on FD 4
   2005/01/25 14:17:50| Adding nameserver xxxxxxxxxxxxx from
/etc/resolv.conf
   2005/01/25 14:17:50| Adding nameserver xxxxxxxxxxxxx from
/etc/resolv.conf

and it seems to be working fine

> www.cygwin.com <www.cygwin.com> 
Server:  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Address:  xxxxxxxxxxxxx

I am behind a firewall (microsoft ISA - not my idea, cannot change it).
squid 2.4.STABLE7, squid.conf is taken from a linux machine running squid
2.5 outside a firewall with very little changes - proxy definition
"cache_peer proxy parent 81 0 default no-query", some paths, cache size.

Any ideas?

:), Leo
