is there a way to know if there's a cable connected to the ethernet card?... I ask this because I have a lombard powerbook, with a dhcp
configured eth0, but if I boot GNU/Linux (ubuntu hoary) it stops
waiting for a dhcp server, I would like to modify the networking
script, so if there's no cable present on the card, don't configure
the eth0 device, only the loopback. Is it possible? Something like
OS X does when it's booting.
I thought this was alrady the default behaviour in Debian (I run the testing tree). When my 8500 boots up, if I don't have the network cable plugged in, it will pause while the networking scripts try to acquire a connection, but after about a minute or so, it will give up, continue the boot cycle, and just have the loopback interface ... I can't see why this would be different on Ubuntu. I remembered when I was setting up Warty on a PC, the DHCP timeout would be __VERY__ long. But I thought that was just because it was an older machine ...
I would recommend you give it 2-3 minutes to see if DHCP can figure out you don't have a network connected. If you have to wait longer than 5 minutes, I'm not sure where the trouble would be ...
