I issued a static ipv6 address with prefix lenght 120 (according to my network administrator) and ipv6 default route in rc.conf, and issued '/etc/rc.d/network_ipv6 start'. ifconfig bge0: bge0: flags=8843 metric 0 mtu 1500 options=9b ether 00:f5:0b:3d:3b:e4 inet6 fe80::217:a4ff:fe8d:33e8%bge0 prefixlen 64 scopeid 0x1 (ipv4 stuff) inet6 2a02:1823:1002:b1 prefixlen 120 (this is the static address) media: Ethernet autoselect (100baseTX ) status: active I enabled inet6 rules and in /etc/pf.conf like this: pass in on $ext_if inet6 proto tcp from any to $ext_if port http pass out on $ext_if inet6 proto tcp all pass out on $ext_if inet6 proto icmp6 all icmp6-type echoreq keep state pass in on $ext_if inet6 proto icmp6 all icmp6-type echoreq Locally, ipv6 seemed to work OK as I could ping6 localhost and hostname. However, ipv6 connections from outside were still being blocked by pf, so I was trying to solve that issue. At one point, I did a 'ping6 ipv6.google.com', after which the machine dropped the ssh connection. I connected to the console using ILO, only to see it rebooting. It was writing vmcore.0 at that point, which I interrupted using ctr-c, since I was not sure how long it would take. Now I have those files in /var/crash: bounds info.0 minfree vmcore.0 info.0 contains: Dump header from device /dev/da0s1b Architecture: amd64 Architecture Version: 2 Dump Length: 1812742144B (1728 MB) Blocksize: 512 Dumptime: Wed Jun 8 12:56:40 2011 Hostname: server Magic: FreeBSD Kernel Dump Version String: FreeBSD 7.4-RELEASE #0: Fri Feb 18 01:55:22 UTC 2011 root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC Panic String: page fault Dump Parity: 2017522204 Bounds: 0 Dump Status: good The size of vmcore.0 is 767M. It is probably incomplete. In /var/log/messages I have: Jun 8 12:59:31 server savecore: reboot after panic: page fault Jun 8 12:59:31 server savecore: writing core to vmcore.0 I have not built a kernel locally, so will I be able to read the vmcore.0 using kgdb without local sources? Not sure if I can submit a PR for this either, thus I would like to learn more about this issue at first. I searched the freebsd bugs database, but found nothing really similar. Any help about how to handle this issue would be much appreciated. nick
