Ethernet help

["redhat nextnet com" <redhat nextnet com>]

Is there any software out there that I can use to test to see whether or not
my ethernet card is actually working? I have a two port card. Both lights
work on the card but I can't get either port to work. Both are configured as
follows:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx
NETMASK=255.255.255.248
GATEWAY= xxx.xxx.xxx.xxx

I have stopped and restarted the machine. Both eth0 and eth1 start up as
"OK" on startup. Can't ping in, can't ping out.
What am I missing?
