HI Folks, I've got two boxes that I recently moved from -stable to 9.1rc1. I did them one at a time, with about a week between the upgrades. After the first upgrade, I noticed something strange with networking but didn't really dig into it much. After the second upgrade immediately experiencing the same issues, I figured it seemed to be something related to 9.1rc1.
What I am finding is that packets that originate from the FreeBSD boxes do not get returned when running IPv6. V4 seems to be fine. I can also shell into the boxes without issue, which is strange, since I would figure if there were network issues, then I would see it for both in and out. So box sends a syn outbound, ack is never returned. I can see on the destination boxes interface that the return packet is never actually generated. Running tcpdump -nei pflog0 doesn't show any blocked return packets, so I think the packets are just not getting generated. I don't really understand how this could be honestly. I first thought it was an issue with a Linux box, since its running a service that both boxes are trying to talk to, but I don't think this is the case. I see the same behavior when I try to shell from one FreeBSD box to the other. I was encouraged to send a note to the list, even though I have very little concrete. Is anyone else seeing any strange IPv6 related networking issues on 9.1RC1? -- Zach _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
