This behaviour is a result of the upstream fix for upstream bug 2997. It is still present in all Squid-3 (will be fixed in Squid-4). When Squid is assigned an explicit listening IP and that IP has reverse-DNS it is used instead of halting startup.
Only the first http_port or https_port is checked in the affected versions. To prevent localhost being used, do not configure it as the primary listening address for Squid. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to squid3 in Ubuntu. https://bugs.launchpad.net/bugs/1098641 Title: visible_hostname defaults to hostname of first http_port IP, not get_hostname() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/squid3/+bug/1098641/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
