How to restart the networking after changing the network configuration?

[Zhengyu Guo]

Hi,

I tried it but it still doesn't work. Probably this is not for my case.

What I did was I changed the DHCP to static IP with bridge. The following
is the configuration.
~~~
auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
        address xxx.xxx.xxx.xxx
        network xxx.xxx.xxx.xxx
        netmask xxx.xxx.xxx.xxx
        broadcast xxx.xxx.xxx.xxx
        gateway xxx.xxx.xxx.xxx
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0
~~~

Do you have any other idea on how should I restart the networking to make
the bridge work?

Thanks

Zhengyu
