I usually set static IP addresses on my Linux boxes, and I set the gateway address in the same file (i.e. /etc/sysconfig/network-scripts/ifcfg-eth0).

I've inherited a VmWare ESX box (modified Red Hat 7.3), that only has the IPADDR and NETMASK parameters set, no mention of GATEWAY, yet the machine has no problem pinging machines outside it's subnet.

I ran the route command and saw the correct gateway address referenced there.

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.48.0 * 255.255.252.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 10.10.48.1 0.0.0.0 UG 0 0 0 eth0

Obviously, the default gateway address is set somewhere else. Can someone tell me other places it could be set besides in the configuration file of the ethernet port itself?

Thanks

It is probably in:
/etc/sysconfig/network

fgrep -r 10.10.48.1 /etc/*

Thank you very much...

It was in /etc/sysconfig/network.

fgrep -r 10.10.48.1 /etc/*

Great tip! I didn't know about fgrep. This will help me find all kinds of stuff from now on.

Again, thanks for the help
