I have created a Network Bridge in Ubuntu 11.10 and have a second computer accessing the network and internet through the bridge. The bridge comes up and is active before the log on screen but after about 30 mins of idle time for the Ubuntu computer the bridge becomes disabled. I can no longer ping the bridge from the second computer. I can type "sudo /etc/init.d/networking restart" and I can start using the internet through the bridge again.
I have tried modifying my power settings, telling the computer to never to go sleep or hibernate.
I think there is something simple that I am missing but my adapters config file consists of:
auto lo eth0 eth1 bridge0 iface lo inet loopback iface eth0 inet manual iface eth1 inet manual iface bridge0 inet static address x.x.x.x netmask x.x.x.x network x.x.x.x broadcast x.x.x.x gateway x.x.x.x nameservers x.x.x.x bridge_ports eth0 eth1 pre-up ip link set eth0 promisc on pre-up ip link set eth1 promisc on bridge_fd 0 bridge_hello 2 bridge_maxage 12 bridge_stp off ip link set bridge0 promisc on
Not sure if I set something I should not of or if there is a setting that I am missing to prevent this. I want this connection to be running when the computer boots without a user being logged in, which is currently how it is working.
