How to stop 2 default gateways?
I have two network cards, one is on a 71.252.x network and one on a
192.168.x network. I would like my default gateway to be the 71.252.x
with only 192.168.x traffic going through that particualr card. When I
setup /etc/network-scripts/ifcfg-eth0 and eth1 then ifup I get two
0.0.0.0 gateways - How can I stop Mandriva doing that?
The device below should ONLY route to 192.168.168.254
[root@cartman network-scripts]# more ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.168.9
NETMASK=255.255.255.0
GATEWAY=192.168.168.254
ONBOOT=yes
METRIC=1
MII_NOT_SUPPORTED=no
USERCTL=no
DNS1=71.252.202.195
RESOLV_MODS=yes
IPV6INIT=no
IPV6TO4INIT=no
Everything else should route through this card
[root@cartman network-scripts]# more ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
IPADDR=71.252.202.195
NETMASK=255.255.255.0
GATEWAY=71.252.202.1
ONBOOT=yes
METRIC=10
MII_NOT_SUPPORTED=yes
USERCTL=no
DNS1=71.252.202.195
DNS2=4.2.2.2
RESOLV_MODS=yes
LINK_DETECTION_DELAY=6
IPV6INIT=no
IPV6TO4INIT=no
However there are two default routes.
[root@cartman network-scripts]# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
71.252.202.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1

169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1

0.0.0.0 192.168.168.254 0.0.0.0 UG 0 0 0 eth0
0.0.0.0 71.252.202.1 0.0.0.0 UG 0 0 0 eth1
Any idea how I can fix this using the scripts or should I write my own
to start eth0 after eth1 if configured?

Just remove the above line.
You may also want to add a zeroconf line to /etc/sysconfig/network
$ cat /etc/sysconfig/network
NETWORKING_IPV6=no
NOZEROCONF=yes <===== line to add.
NEEDHOSTNAME=no
NETWORKING=yes
HOSTNAME=wm81.home.test

Thanks, I'll give that a try.

My some odd freak of computing, whenever I traceroute a site it goes out
the 71.x network card and only 192.168.x does out that particular card.
Quite unexpected but works for me, not a proper solution tho.
