I try to setup networking with a fresh CENTOS4.4 installation. Upto now
I have 20 installations, most of them FC3/FC4 and RHEL3.
I noticed that the default gateway is not setup properly when using
Centos.
[root@raaf ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.101.0 * 255.255.255.0 U 0 0 0 eth1
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
default 192.168.101.1 0.0.0.0 UG 1 0 0 eth1
Networking is setup done by using dhcp, and this seems to work OK.
Problem is however that the gateway should be 192.168.101.2 and not
192.168.101.1 (does not exist). If I manually add the gateway,
networking is OK:
Sounds like you need to fix your dhcp server so that it hands out the
proper information.
Thanks Jim. That triggered the right thing. I had two servers specified
in my dhcpd configuration:
option routers 192.168.101.2, 192.168.101.1;
option routers ip-address [, ip-address... ];
The routers option specifies a list of IP addresses for routers on
the client’s subnet. Routers should be listed in order of prefer-
ence.
All my other Windows and Linux boxes up to now don't seem to mind. I
checked the routing on other boxes and they show up with both gateways
(the old gateway was replaced a year ago..).
Again thanks, you pointed me to the right spot.
Theo
