I upgraded to 7.2 and now it does not. I am using the tulip ethernet driver and it worked before. It is NOT a kernel issue. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.cd to /etc/init.d 2. type ./network restart Shutting down interface eth0: [ OK ] Shutting down interface ppp0: [ OK ] Disabling IPv4 packet forwarding: [ OK ] Setting network parameters: [ OK ] Bringing up interface lo: [ OK ] Cannot open netlink socket: Address family not supported by protocol Bringing up interface eth0: Additional info: added set -x in script and it seems that in the is_availble this is coming up I think .. + ip -o link + grep -q eth0 Cannot open netlink socket: Address family not supported by protocol + '[' 1 = 1 '
it is definately the ip -o link that is causing problems. The worst part is that it says OK to initializing the eth0 device but you cannot ping the ip address that is supposed to be assigned to the device.
Did you recompile the kernel at all?
Why do I need to recompile my kernel? I am using 2.4.14, and I was using 2.4.14 with RH 7.1. Why should that make a difference? What changed that broke this?
You need CONFIG_NETLINK and CONFIG_RTNETLINK enabled in your kernel. See the release notes. *** This bug has been marked as a duplicate of 55846 ***
This seems to have worked.
