don't know - never used it.

try...

cd /etc/sysconfig/network-scripts
cp ifcfg-eth0 ifcfg-eth1

and then edit ifcfg-eth1 to your liking

simply edit /etc/sysconfig/network

change the hostname to anything you want it to be - suggest that you
make sure this entry also exists in /etc/hosts

Also when using 2 eth devices per above, set the gateway address here...

GATEWAYDEV=eth0 # fix for your situation
GATEWAY=ip_addr_of_gateway

dmesg|less

or

can't help with the last 4 - perhaps the asterisk lists might be of more
