Здравствуйте.
Почему-то сеть не работает в VE - вроде все распрекрасно настроил, а не работает даже пинг на HN.
===================================
На HN:
ip a
2: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 100
link/ether 00:1c:c0:41:84:80 brd ff:ff:ff:ff:ff:ff
inet 192.168.176.11/24 brd 192.168.176.255 scope global eth0
inet 192.168.176.12/24 brd 192.168.176.255 scope global secondary eth0:0
inet6 fe80::21c:c0ff:fe41:8480/64 scope link
valid_lft forever preferred_lft forever
1: sit0: <NOARP> mtu 1480 qdisc noop
link/sit 0.0.0.0 brd 0.0.0.0
11: tunl0: <NOARP> mtu 1480 qdisc noop
link/ipip 0.0.0.0 brd 0.0.0.0
13: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue
link/void
==================================================
На VE:
ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
3: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue
link/void
inet 127.0.0.1/32 scope host venet0
inet 192.168.176.12/32 brd 192.168.176.12 scope global venet0:0
========================================================
На VE пингую ya.ru:
ping 213.180.204.8
PING 213.180.204.8 (213.180.204. 56(84) bytes of data.
--- 213.180.204.8 ping statistics ---
35 packets transmitted, 0 received, 100% packet loss, time 33998ms
=========================================================
На HN tcpdump -n -i venet0 показывает:
22:10:56.283829 IP 192.168.176.12 > 213.180.204.8: ICMP echo request, id 37436, seq 5, length 64
22:10:57.283962 IP 192.168.176.12 > 213.180.204.8: ICMP echo request, id 37436, seq 6, length 64
22:10:58.284094 IP 192.168.176.12 > 213.180.204.8: ICMP echo request, id 37436, seq 7, length 64
22:10:59.283228 IP 192.168.176.12 > 213.180.204.8: ICMP echo request, id 37436, seq 8, length 64
==========================================================
На HN все работает - пинги идут. Из-за чего это может быть? Система - centos 5.2 с последним ядром(на прошлом тоже самое), все сделано по хауту, но сеть не работает.
