Two Network Cards

[jshankle]

I have a system that has two Ethernet ports. One is set up with a static ip address and will connect to the internet just fine. The other one is set up as dhcp but will not connect to the internet. Does anyone have any idea on what steps i should take to make this work. I have tried searching Google but the results are flooded with just things pertaining to having a single network plug that is either static or dhcp, not a system using both.

The reason I'm running two is the static port will connect to the outside world while the dhcp will connect to a computer cluster (warewulf). Im also new to Linux and networking

Thanks for any help,
Justin

There are two different network management schemes n Fedora. One is the old, traditional, script oriented 'network.service' and The other is the new ,shiny, but limited NetworkManager.service'.

NetworkManager has a lot of great features for managing wifi supplicants and setting up VPNs with plugins, BUT the last I read it only manages one interface at a time. 'network' will handle multiple interfaces and some alternative (non 802) networks and bridges, but is clueless about wifi supplicants. You clearly need to install & configure 'network.service'

The package you want to install is 'system-config-network' and the configuration tool has the same name. (yum -y install system-config-network). Start at the 'hardware' tab.

After you have the two interfaces configured then you can arrange for 'network' to start at boot with ...
systemctl disable NetworkManager.service
systemctl enable network.service

and when you are ready to switch (after config)
systemctl stop NetworkManager.service
systemctl start network.service
to immediately stop/start the services.

Of course you need root privileges for these commands.
