eth0 has two addresses within the same network. Link scope route has a src= specifying the first IP address. However, when doing a connect to one of the IP addresses on eth0 from the machine itself (unbound socket) the source address ends up identical to the destination address, not to the src= in the route. Is this a feature or a bug? Example: ip addr: 1: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:13:72:12:39:3f brd ff:ff:ff:ff:ff:ff inet 172.17.1.48/16 brd 172.17.255.255 scope global eth0 inet 172.17.2.93/16 scope global secondary eth0 ip route: 172.17.0.0/16 dev eth0 proto kernel scope link src 172.17.1.48 default via 172.17.1.118 dev eth0 proto zebra metric 2 When doing a nc <anyhost> discard then <anyhost> sees a connect originating from 172.17.1.48. This is correct. However, when connecting to the second IP address as in nc 172.17.2.93 discard a TCP connection is created originating from 172.17.2.93 instead of from 172.17.1.48 -- Frank - To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
