From: Eugene Prokopiev <prokopiev@stc.donpac.ru> To: Sysadmins@lists.altlinux.org Subject: [Sysadmins] OpenVZ : диагностика неисправности veth-интерфейсов Date: Sat, 16 Dec 2006 10:20:27 +0300 Message-ID: <45839E3B.408@stc.donpac.ru> (raw) Здравствуйте! Есть 4 VE с veth-интерфейсами и с адресами 10.1.0.[1-4]. Концы veth-интерфейсов, смотрящие в HN, объединены в бридж, соответственно все 4 VE должны друг друга видеть. И 3 VE действительно видят друг друга, а четвертый - никого (Destination Host Unreachable). Вот что показывает tcpdump на HN при попытке пропинговать 10.1.0.3 с 10.1.0.4 и 10.1.0.2: # tcpdump -i br0 tcpdump: WARNING: br0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on br0, link-type EN10MB (Ethernet), capture size 96 bytes 10:10:09.785658 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:09.785711 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:10.785706 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:10.785746 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:11.785754 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:11.785788 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:12.797803 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:12.797850 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:13.797853 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:13.797890 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:14.797906 arp who-has 10.1.0.3 tell 10.1.0.4 10:10:14.797944 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:56.958047 arp who-has 10.1.0.3 tell 10.1.0.2 10:10:56.958107 arp reply 10.1.0.3 is-at 00:12:34:56:78:05 (oui Unknown) 10:10:56.958126 IP 10.1.0.2 > 10.1.0.3: ICMP echo request, id 40204, seq 1, length 64 10:10:56.958170 IP 10.1.0.3 > 10.1.0.2: ICMP echo reply, id 40204, seq 1, length 64 10:10:57.954114 IP 10.1.0.2 > 10.1.0.3: ICMP echo request, id 40204, seq 2, length 64 10:10:57.954139 IP 10.1.0.3 > 10.1.0.2: ICMP echo reply, id 40204, seq 2, length 64 10:10:58.954190 IP 10.1.0.2 > 10.1.0.3: ICMP echo request, id 40204, seq 3, length 64 10:10:58.954213 IP 10.1.0.3 > 10.1.0.2: ICMP echo reply, id 40204, seq 3, length 64 Как вообще решать такого рода проблемы?
