A specific application I use doesn't play well with network-manager. I would like to purge network-manager and configure my connections manually.
I have a dhcp connection to the network, and a static ip connection to an ethernet device.
How should I configure my ubuntu?
I tried setting /etc/network/interfaces:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto eth3
iface eth3 inet static
address 192.168.155.130
netmask 255.255.0.0
gateway 192.168.155.1
But that didn't work at all. Are there other things I need to consider?
