Hi Im having a strange issue that seems to be plaguing all 3 of my HP ProLiant DL360 servers that are all running an identical configuration of CentOS 6.4.
It seems that when the network daemon is restarted (or just started when it was not) it fails when it attempts to bring up the interface, eth0 in this example. however when I issue ifup eth0 it takes 2 seconds and then its working like it should. The exact output is as follows.
[root@Hostname1 ~]# service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Determining IP information for eth0... failed; no link present. Check cable? [root@Hostname1 ~]# ifup eth0 Determining IP Information for eth0... done.
I have no idea why this happens, and it only happens some of the time. I do have the interface set to start on boot as well as checked the cables. I'm at a loss, any help would be nice, thanks in advance.
EDIT: Here is my ifcfg-eth0
DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes
