I think from the description the squid thing is actually a red herring. (to mix a fishy metaphore). It sounds like your proxy server is not reliably resolving DNS when using IPV6. You will probably see this problem if you run firefox on the server. https://bugs.launchpad.net/ubuntu/+source/netcfg/+bug/24828
not sure how you turned off IPV6, one way is to edit / /etc/modprobe.d/aliases and edit it to have this line: /alias net-pf-10 off ipv6 a better solution would be to fix the actual problem, one way might be to point your proxy at openDNS which works fine with v6. I suspect the DHCP server is pointing your box at a bad router for DNS queries. Alan.
