Linux: ifdown eth0:0 brings down all other virtual network interfaces

Posted on in Categories , , , , , , last updated December 4, 2008

Q. Why do the other virtual network interfaces go down when I bring down eth0:0 under CentOS Linux?

A. There is well known bug is glibc – the GNU C Library, commonly known as glibc, is the C standard library released by the GNU Project.

To fix this problem upgrade glibc version using up2date or yum command:
# yum update
OR
# up2date -u
Upgrading to the latest version of glibc should fix this issue.
