I have a redhat 7.0 server with 10 sub interfaces (eth0:1 - eth0:10) my /etc/sysconfig/network-scripts/ifcfg-eth0:x interfaces look like so: DEVICE=eth0:1 BOOTPROTO=none BROADCAST=209.221.163.127 IPADDR=209.221.163.71 NETMASK=255.255.255.192 NETWORK=209.221.163.64 ONBOOT=yes After a reboot or /etc/init.d/network restart some sub interfaces lose their ability to comunicate with any network nodes not on the local subnet. This has happend both times I have rebooted and only start working after about 30 /etc/init.d/network restarts/ifdown/ifups's until finally one of the sub interfaces come up. It seems like after the system is restarted some sub-interfaces do not get assigned a default gateway. I have tried adding "GATEWAY" and "GATEWAYDEV" as well as playing with "BOOTPROTO" but with no luck. I would be willing to provide access to this box if needed. My email is: shane
What does your routing table look like?
Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 209.221.163.64 * 255.255.255.192 U 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default 209.221.163.65 0.0.0.0 UG 0 0 0 eth0 This is how the route tabled looked when it is NOT working as well.
Do you have an ifcfg-eth0 file? What did your /etc/sysconfig/network script look like with GATEWAY and GATEWAYDEV added?
[shane@master shane]$ cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=master.geeklords.org GATEWAY=209.221.163.65 GATEWAYDEV=eth0 This file was created by a redhat 7.0 fresh install, the only files I played with are the ones I created (i.e. the sub interface files eth0:x). Redhat 7.0 install also created a /etc/sysconfig/network-scripts/ifcfg-eth0 and it looks like this: DEVICE=eth0 BOOTPROTO=static BROADCAST=209.221.163.127 IPADDR=209.221.163.98 NETMASK=255.255.255.192 NETWORK=209.221.163.64 ONBOOT=yes I noticed this problem after doing a default server install and then aimmediately creating the ifcfg-eth0:x files. I should be able to reproduce the problem merely by rebooting. I can give you an account on the machine if it helps, email me with an account if you would like to take this route.
Is there any other information you require?
This report is really old now. I don't think it's kinda that can be tested and reproduced on a newer system easily. Better closed?
Closing out bugs on older, no longer supported releases. Apologies for any lack of response. Please reopen if it persists on current releases.
