Dear Amos, Thanks for the reply. We are using the same DNS servers for our existing proxy server which is ISA2000 is working properly without any problems. We want to shift from MS-ISA2000 proxy server to Linux Squid proxy server, so we are building up this new proxy server. More over if I access the internet from the Ubuntu proxy server itself, we don't get any such errors. Can you / anyone let me know how can we resolve these issue.

RE: [squid-users] errors while opening sites
Dear Mariel, This is not happening about any particular site. This can happening with any site in next 3-5mins time the same site/web page works properly. Just a thought. Check that negative_ttl is set to 0 seconds (default when unset on older squid was 5 minutes which is suspiciously similar) and that negative_dns_ttl is at least 10 seconds (or unset for default). Also check that they are actually being generated by your own squid, your upstream ISP may be having trouble with an old transparent proxy. Amos ~~~ Thanks Regards, Sameer Shinde.

But I was waiting to resolve this problem 1st once everything works properly, I wanted to upgrade it to 3.0 So far I'm searching for the documentation for, how to upgrade the squid 3.0 in ubuntu as some parameters are changed in Ubuntu I need to do the customized installation.

This can happening with any site in next 3-5mins time the same site/web page works properly. Just a thought. Check that negative_ttl is set to 0 seconds (default when unset on older squid was 5 minutes which is suspiciously similar) and that negative_dns_ttl is at least 10 seconds (or unset for default). Also check that they are actually being generated by your own squid, your upstream ISP may be having trouble with an old transparent proxy. Amos ~~~ Thanks Regards, Sameer Shinde.

I'm not able to bring the server in live mode due to this problem. The DNS server being used by your system for lookups is having major problems. You will need to do some serious debugging to find out why. Things to look for are DNS server overload, traffic congestion, lack of recursive queries, etc. Amos

Dear All, I've installed squid 2.6 installed on my ubuntu8.0.4 server. I'm getting errors like attached one frequently.

The error appears for any domain is not particular to any domain. Can anyone help me out in this.
