OpenVPN quits due to nonexisting /dev/net/tun

[aladar42]

I am running the latest version of XBian, and running OpenVPN fails.

Sat May 13 13:42:01 2017 ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)
Sat May 13 13:42:01 2017 Exiting due to fatal error

There are several "fixes" that I found on the internet (running modprobe tun, etc), that do work, but only until restart. After restarting the device, OpenVPN fails to start again. Manually creating the /dev/net/tun dir also works only until reboot. Any idea what to do?

Please add tun to /etc/modules (don`t forget to add after tun :smile:)

cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

tun

/etc/modprobe didn't exist, so I created it.

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

uinput
tun

However,

xbian@xbian ~ $ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

am I forgetting something? Is it possible to ship it already configured with the system?

Ehm, sorry. Your Pi Zero W clock issue is confusing me and my provider has heavy issues at the moment - that makes me crazy

/etc/modprobe is not correct, I meant /etc/modules of course

Thanks, working now. Any chance to push it to the default modules file in the future? Also, got another error, I'm assuming that's because XBian doesn't support ipv6? (Commenting out ipv6 tunnelling fixed it)

OK, sorry, false alarm, OpenVPN service still not starting automatically. I can only run it manually.

xbian@xbian ~ $ sudo service openvpn status
[FAIL] VPN 'mullvad_linux' is not running ... failed!

Not sure where the log file is.

You have to install/enable syslog daemon, I prefer rsyslog

Seems that your openvpn service is not set to autostart. You can add openvpn as service in xbian-config (console and Kodi GUI version both works) and enable autostart

[mkreisl]

XBian supports IPV6, but it's disabled per default

Thanks, looks like it starts now. I was used to desktop Debian adding the service to autostart automatically. :x However, it seems to start after Kodi initializes completely, wouldn't that be an issue?

Don't think so. If you need openvpn up before Kodi starts, you can add openvpn to file /etc/default/xbmc, parameter WAITFOR

# Put name of all processes which XBMC should wait for before it will be started.
# e.g. WAITFOR=""
WAITFOR="openvpn"

Cool, all working perfectly now. Thanks. I'll close this issue, but I would still like to request if /etc/modules could come with tun already set up, so that people won't have to bother the devs like I did. :)
