CentOS 6.0 networking
Posted on 2012-04-10
I am having trouble with intial network (ifconfig and route) settings on my new server, doing it three different ways to no avail. I have set the interface (ifconfig...) and the default routing (route add...), as well as use the 'setup' utility, as well as manually editing the /etc/sysconfig/network-scripts/ifcfg-eth0 (and route-eth0) files. While I have been able to ping the default gateway, I can't get past it. I know that default gatework works because other devices on the net have been successful. If I try to ping past the default I get something similar to a "route unreachable" error message.
Furthermore I can't save the configuration when I try to do it thru the setup utility or when I do a /etc/inid.d/network save and restart. Even when I see the /etc/sysconfig/network-scripts/ifcfg-eth0 and the /etc/sysconfig/network-scripts/route-eth0 have the correct parameters...(I think)
What am I missing?
