HOWTO write a udev rule to awaken fetchmail after eth0 is up
I'm trying to write a udev rule to awaken a system-wide fetchmail daemon
whenever eth0 is brought up, but I'm lost about which event to capture.
Before udev, I did this in /etc/network/interfaces:
iface eth0 inet dhcp
post-up /etc/init.d/fetchmail start || true
pre-down /etc/init.d/fetchmail stop || true
I'd like to do functionally the same with udev.
I've read the docs that come with udev and changed this line in
to get a feeling of what events are produced, but I'm still not sure of what
event I should capture.
Has anybody done this and could share the tips ?
