1我需要在Linux的界面上使用几个IP,然后切换它,但它不起作用。
例如:ip route src not working
# ifconfig

# ip route

192.168.1.0/24 dev eth0 scope link src 192.168.1.99
# ping 192.168.1.50
PING 192.168.1.50 (192.168.1.50) 56(84) bytes of data.

64 bytes from 192.168.1.50: icmp_req=3 ttl=255 time=1.05 ms
,然后我用卷曲
# curl 192.168.1.50
和tcpdump的:
13:24:02.009094 IP 192.168.1.1 > 192.168.1.50: ICMP echo request, id 8919, seq 347, length 64

..*...F....
和源IP仍是192.168.1.1,我在做什么错了?
UPD:顺便说一句,在Ubuntu 10.04上用2.6.32内核试了一样的东西,一切正常,甚至不需要在“ping”命令中加上“-I”,它就会在我的内核中接受。 0)有人破坏了这个功能。
尝试卷曲,更新后 –
我也做“ping 192.168.1.50 -I eth0:1”,并没有改变tcpdump,它需要相同的IP –
