Uping eth0 after a black out

[Basher52]

This evening we had a black out after a short thunderstorm and I wonder if there is a way to 'ifup' a NIC after that?
I do have 'ONBOOT=yes' but when the power was up my ISP didn't have their servers up and running totally.
I need something that can 'ifup' a NIC if it ain't up after a start/restart, such in this case.
Some years ago, after a black out the ISP didn't work until about 30 minutes later and that made my have the connection down for all day since I was at work and couldn't sit in front of the machine to start it manually.

You could put something as simple as this in root's cron to run like every 15 minutes:

Code: Select all

if ! /bin/ping -c2 www.google.com; then /sbin/ifdown eth0; /sbin/ifup eth0; fi &> /dev/null

Basically all it does is send 2 ping packets to google and if it doesn't get a response it will down and up your eth0.
