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

Как вообще решать такого рода проблемы? Куда еще заглянуть?
