Hi all,
With SystemD, how can I make certain service dependent on certain network interfaces being up?
For example, I have an 802.1ad bond interface I need to wait on for being up (this interface has no ip address assigned, it is used to capture networks packets with a tcpdump’s script). Every time this service fails because bond interface is not up.
I have configured the service as:
[Unit]
Description=tcpdump capture script
After=network.target
Wants=network-online.target
But it doesn’t work …. Any tip or trick?
Just add a line to the tcpdump script to wait for the interface.
Something like this:
until ifconfig -s | grep -q '^bond0' ; do sleep 1 ; done
Cheers Tony
