I have not seen this before but this is on all kernels until now. Network will not start on Mac mini if there is no Monitor attached.

Comment 4 Steve 2010-06-01 19:36:49 UTC
Other Intel systems i have checked, the network will be enabled without a Monitor.

Comment 5 Dan Williams 2010-06-15 18:26:09 UTC
What are the contents of any /etc/sysconfig/network-scripts/ifcfg-* file?  If you have ONBOOT=no in there, that's a result of using the DVD installer, which does not enable networking by default since you didn't use the network to install from.  If so, change that to ONBOOT=yes and you'll get networking automatically brought up.

If you have no ifcfg-* files in /etc/sysconfig/network-scripts, then you don't have any networking configuration, and thus there's nothing to bring up.  Let me know!

Comment 6 Steve 2010-06-15 19:06:56 UTC
I have "ONBOOT=yes" in my ifcfg-eth0. The network doesn't start only if there is no monitor connected! If there is a monitor connected, the network starts.

Comment 7 Dan Williams 2010-06-28 21:27:05 UTC
Can you attach/paste the following for me when the problem occurs?

1) any /etc/sysconfig/network-scripts/ifcfg-* file
2) output of 'ifconfig -a'
3) /var/log/messages


Comment 8 Steve 2010-06-29 07:52:46 UTC
I close this bug because i think this is an problem of the Mac itself. It will not start if no monitor is connected.
