Hy,
I have a Centos 3 server installed with qvcs, NAT and DNS packages. I wanted to block www.meebo.com and I installed squid for this. It seems to work but I receive a lot of TCP_MISS when users acces the net. I don't know why but it seems to work even with this.
The problem is now that some users must acces some sites like preview.my-site.com that are not listed in the DNS, where are posted. Before I installed squid they could acces it by puting in Windows/Sustem32/Drivers/etc/hosts the ip addres and the name of this previews and it worked. Afther I installed squid it doesn't work, on the logs I see the TCP_MISS/503 error. The regular TCP_MISS were with /200 error. If I stop squid it works again.
I tried to put those ip and names in /etc/hosts on the server but it still doesn't work.
Thanks to all
