This will break other clients, too. For instance, a BIND forwarder without source port randomization, who happens to have multiple queries in flight. Has it been verified that the second DNS packet actually leaves the box? I think there was word of a kernel bug leading to dropped UDP packets which might cause this. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
