Hello

got same king of problem, on ubuntu precise my tun interface is tunl0

openvpn search for

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2)

then the ifconfig failed :

ifconfig 10.8.0.1 pointopoint 10.8.0.2 mtu 1500
______^^ missing interface name...

If I do the ifconfig manually with the right interface name :

sudo ifconfig tunl0 10.8.0.1 pointopoint 10.8.0.2 mtu 1500

it's ok :

tunl0 Link encap:IPIP Tunnel HWaddr
inet adr:10.8.0.1 Masque:255.0.0.0
UP RUNNING NOARP MTU:1500 Metric:1

collisions:0 lg file transmission:0
Octets reçus:0 (0.0 B) Octets transmis:0 (0.0 B)

How can I configure openvpn to use tunl0 interface instead of tun0 ?

Get your VPS provider to enable tun for you.
