Fix systemd unit

[SupinePandora43]

CAP_NET_ADMIN was required to make it run under systemd (ArchLinux)

[txtsd]

Can you show me the specifics of how you're using it such that it needs CAP_NET_ADMIN? It runs fine for me without it.

Right now I've been getting

ноя 18 00:34:26 supine dpitunnel[76274]: Sniff raw socket creation failure. Errno: Operation not permitted
ноя 18 00:34:31 supine dpitunnel[76274]: Sniff raw socket creation failure. Errno: Operation not permitted
...

previously I received setsockopt operation not permitted.

Are you using the dpitunnel package on the AUR?

If not, paste the output of systemctl cat dpitunnel
