[ubuntu-uk] Squid proxy box with serious IPv6 DNS problem...

[LeeGroups]

Alan,

I'm actually using OpenDNS's servers (after using the ISP's), what I 
really don't understand is how Apt is working perfectly, but Squid and 
Wget don't...

I saw that post before, it's what I used to supposedly turn off IPv6.

I can't run FF on the server, no gui installed...
