ahoj! i had 5-CURRENT as of Dec 10, and if_gre tunnel to some unknown Cisco router was running ok. then i upgraded to 5.2-RELEASE and the tunnel went down. 5.2.1-RC is no better as well (perhaps, because of the same 1.14 revision of sys/net/if_gre.c). the only symptom making sense to me is that tcpdump shows mostly some weird fragments and shows a 'proper' packet going out only rarely (right after an ifconfig gre0): 00:19:43.595205 0:c:f1:8a:e1:f1 0:a0:c9:92:cd:4c ip 98: margo > om-vlvpn0: gre margo-omni-smsc > omni-margo-tun: icmp: echo request [ttl 1] (id 33753, len 60) (ttl 30, id 4101, len 84) 00:19:43.599861 0:a0:c9:92:cd:4c 0:c:f1:8a:e1:f1 ip 98: om-vlvpn0 > margo: gre omni-margo-tun > margo-omni-smsc: icmp: echo reply (ttl 255, id 33753, len 60) (ttl 252, id 46495, len 84) 00:19:43.600197 0:c:f1:8a:e1:f1 0:a0:c9:92:cd:4c ip 98: margo > om-vlvpn0: gre (frag 4105:64_at_56192) (ttl 30, len 84) 00:19:48.607214 0:c:f1:8a:e1:f1 0:a0:c9:92:cd:4c ip 98: margo > om-vlvpn0: gre (frag 4129:64_at_64) (ttl 30, len 84) help?.. :) ifconfig: gre0: flags=b051<UP,POINTOPOINT,RUNNING,LINK0,LINK1,MULTICAST> mtu 1476 tunnel inet 213.226.139.60 --> 195.22.176.207 inet 193.110.9.78 --> 193.110.9.77 netmask 0xffffff00 routing table: omni-margo-tun gre0 UHS 0 0 gre0 margo-omni-tun localhost UGHS 0 0 lo0 omni-margo-tun is the other end of the tunnel margo-omni-tun is the local end of the tunnel gre0 creation: /sbin/ifconfig gre0 create /sbin/ifconfig gre0 margo-omni-tun omni-margo-tun link0 up /sbin/ifconfig gre0 tunnel margo om-vlvpn0 /sbin/route add -host margo-omni-tun localhost /sbin/route add -host omni-margo-tun margo-omni-tun -- Tomas "Verbaitis" Verbaitis ** http://megalogika.lt * šita gudri beždžionė moka dirbti su kompiuteriu *Received on Tue Feb 03 2004 - 23:47:06 UTC
