Trying to set up OpenVPN server on a vps
Solution 1
You are using an OpenVZ-based VPS provider. The provider must enable TUN/TAP in your container before you will be able to use OpenVPN (or anything else that relies on TUN/TAP).
Solution 2
You have not /dev/net/tun
node in your /dev
directory.
Try to create it:
cd /dev
mkdir net
cd net
mknod tun c 10 200
chmod 666 tun
Or you can try, according to this article, use this command: openvpn --mktun
If will openvpn still complain about non-existent tun interface, try use modprobe tun
command. But on mine Ubuntu have kernel support for tun
interface compiled in.

I'm trying to set up an OpenVPN server on my VPS for myself when I'm in public places, using this tutorial, http://tipupdate.com/how-to-install-openvpn-on-ubuntu-vps/
However whenever I try to start the server, it gives me this,
root@vps:~# /etc/init.d/openvpn start * Starting virtual private network daemon(s)... * Autostarting VPN 'server' [fail]
The log contains this
Tue Dec 11 10:53:32 2012 Diffie-Hellman initialized with 1024 bit key Tue Dec 11 10:53:32 2012 /usr/bin/openssl-vulnkey -q -b 1024 -m <modulus omitted> Tue Dec 11 10:53:33 2012 TLS-Auth MTU parms [ L:1542 D:138 EF:38 EB:0 ET:0 EL:0 ] Tue Dec 11 10:53:33 2012 ROUTE: default_gateway=UNDEF Tue Dec 11 10:53:33 2012 Note: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2) Tue Dec 11 10:53:33 2012 Note: Attempting fallback to kernel 2.2 TUN/TAP interface Tue Dec 11 10:53:33 2012 Cannot allocate TUN/TAP dev dynamically Tue Dec 11 10:53:33 2012 Exiting
So obviously it's something to do with the tun, but I don't understand how to fix it.
Thanks!
