setting the default GW permanently

hcclnoodles · 09-14-2005, 12:20 PM

Hi there

When setting up my Fedora Core 3 system I accidentally set my default gateway to the wrong address, so the first thing i did when i booted up was to delete the old gateway

"route del -net 0.0.0.0"

and then set a new one .......

"route add default gw 87.x.x.129 netmask 0.0.0.0 eth0"

however, when I reboot, the original (wrong) gateway address comes back again ??

does anybody know which file I edit to set this permanetly ????

any help woul;d be greatly appreciated

Assuming it's the same as Mandriva, look in /etc/sysconfig/network

ok as far as im aware it should indeed be in etc/sysconfig/networking/devices but that directory is empty !!

Somebody said on another forum said create a file called ifcfg-eth0 (as eth0 is one of my nic id's) and in that file create a line

GATEWAY=x.x.x.x

but....a) this doesnt work and b) Id like to know where the existing information is stored ....it must be somewhere !!!!!!!!!

Google indicates /etc/sysconfig/static-routes is another possibility.

Or use grep to find the file - replace IP address below with your wrong gateway:
grep -r '192.168.1.1' /etc/sysconfig

Well if its not a great solution but this should work. U can put a executable shell script which should read some thing like this
route del default
route add default gw X.X.X.X
and put that file in init.d/ and add that file name along with the path in rc.local
make sure that u make it executable ( The file) run chmod a+x routingfile

By the way isnt it /etc/sysconfig/network-scripts/ifcfg-ethX
where u should look at

Best thing is

make sure that ..

/etc/sysconfig/network-scripts/ifcfg-ethX

of all the files only one of these files have a
GATEWAY=x.y.z.a

and no other file has that keyword in it.

that should about do it.
