[systemd-devel] Starting up service after my openvpn connection turns up

[Matthew Karas]

I am trying to start a dropbear service after my openvpn service starts up.

-----------------------------------
[Unit]
Description=SSH Per-Connection Server
Wants=dropbearkey.service
After=syslog.target dropbearkey.service
Wants=openvpn at equipment.service
After=openvpn at equipment.service
-----------------------------------


But I would like to start up the service after "tun0" interface is
available (made by openvpn).

How do I find out what to put in "Wants" and "After" for tun0?  I
can't seem to find anything related

Also if there is a better way to get dropbear to start after tun0 has
appeared I'm open to doing that as well.  My goal is to have my ssh
server only look at my openvpn address and ignore ssh requests that
are not from the vpn iface.  I'm thinking I can do this with a script
setting up drop bear with the -p option (and looking for my tun0 ip4
address and using it).

Many Thanks,
Matt Karas
