I tried to set up wireguard on dfly for the first time today, without
success. Any idea what is going wrong?
What I did:
- doas pkg install wireguard
- Created a file "wg". Heavily redacted version:
[Interface]
PrivateKey = XXX
[Peer]
PublicKey = XXX
AllowedIps = 10.167.1.0/24
EndPoint = XXX_host:XXX_port
PersistentKeepalive = 25
- doas ifconfig tun0 create
- doas wg setconf tun0 wg
The last command outputs:
Unable to modify interface: No such file or directory
I also tried the wg-quick script:
- doas ifconfig tun0 destroy
- Renamed wg to "tun0.conf"
- doas wg-quick up ./tun0.conf
Result
falsifian angel-dfly etc $ doas wg-quick up ./tun0.conf
[#] wireguard-go tun0
INFO: (tun0) 2021/05/30 04:04:57 Starting wireguard-go version

ERROR: (tun0) 2021/05/30 04:04:57 Failed to create TUN device: open
/dev/tun0: no such file or directory
[#] rm -f /var/run/wireguard/tun0.sock
My use of "tun0" is just a guess based on some searching; wg(8) and
wg-quick(8) don't actually say which interfaces are meant to be used
with wireguard. (A documentation oversight?)
I was worried maybe it only works on FreeBSD, but DeltaPorts includes a
patch for the wg-quick script, so I guess someone got it working at
some point.
