Network Card Must be Turned on Manually Centos 6.0

Hi,

Everytime I reboot my Centos 6.0 install, the eth0 card stays disconnected. As soon as I manually tweak it, it connects. When I reboot the machine it disconnects again. Every time.

I am also running a Scientific Linux 6.0 and 6.1 beta2 install and I have no problems with the network connection disconnecting.

Has anyone else seen this before? I never had this problem on previous Centos installs.

Oh, by the way all of these are running in virtualbox on the same host. Thanks!

UPDATE: I went into the eth0 confog settings and noticed that the connect automatically box was unchecked. I guess that would do it. :-)

I did not realize it was off by default.

Hi!

I noticed this exact same behavior when I did my first CentOS 6 desktop installation. However I also noticed that this won't happen with the minimal installation (probably because minimal doesn't install NetworkManager) so I wonder if this is a bug to report to CentOS or if it was done because the upstream vendor does the same.

Regards.

Hi,

Yes, interesting. I was wondering the same since I am pretty sure that Scientific Linux 6.0/6.1 defaults to automatic. Hopefully, someone more in the know will chime in...Thanks.

Neither defaults to automatic under all circumstances. See [url=http://wiki.centos.org/FAQ/CentOS6#head-b67e85d98f0e9f1b599358105c551632c6ff7c90]CentOS 6 FAQ #2[/url].
