Why do duplicate configuration files like ifcfg-"ethX" gets created for network interfaces on RHEL5 vmware guests after a reboot?

Solution Verified - Updated -

Issue

  • There are mulitple RHEL 5.8 vmware guests.

  • On 5.8 Linux instances it is seen that in /etc/sysconfig/network-scripts directory there were two entries for eth0.

-rw-r--r-- 3 root root   194 Mar  1 07:50 ifcfg-eth0
-rw-r--r-- 3 root root   142 Mar  1 07:45 ifcfg-"eth0"
  • How would two entries get created, one with quotes around it?

  • This does not allow the interface to load properly at the boot time. Deleting the duplicate files and restarting the interface resolve the issue.

  • Why does this happen?

Environment

  • Red Hat Enterprise Linux 5.8

  • VMware hypervisor.
