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

last updated December 4, 2008 in CentOS, Fedora Linux, Hardware, Linux, Networking, RedHat and Friends, Troubleshooting

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.
