Redhat 8 Activate NIC at boot problem
 

I have a server with two NIC cards and I want the cards to come up automatically at boot.
I have the GUI configuration set so that the cards should be activated when the system boots, but the cards do not start and have to be activated manually.
Also, to further complicate the issue I need to bring the cards up in a specific order (see earlier thread re authentication errors with Sonicwall connection under Redhat 8).

Anyone know which config files I should be touching?

take a look at your files:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1

Delete all "ONBOOT" lines and add one of:
ONBOOT=yes

David,
How does this work with 'network profiles'? If we have two or three profiles on the server how do we know which one will be selected at boot time?

You will need to put:
ONBOOT=yes

In each profile to make it active on boot.
