Setting up gateway address for Linux 5.2


I have a linux machine on a WAN.  The linux machine along with a whole bunch of win pcs are routed by a cisco router.  the router is the gateway.  all local machines can ping the remote pcs but the linux machine has lost its gateway configurations.  I don't know how to setup gateway ip for linux.  I'd appreciate the help.

Just enter the command :

route add default gw xxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the address of the router.

I don't use Redhat, so I can't tell you where you save this so that your machine will execute it on boot up.

On my system, you can configure it by running a utility called netconfig. You can also manually edit the file called /etc/rc.d/rc.inet1. Of course, I don't know if this is the same for RedHat Linux
Edit the /etc/sysconfig/network file and add the gateway address. This will make the changes permanent when you reboot.
