I'm trying to run vpnc I get this error
vpnc-connect: can't open /dev/net/tun, check that it is either device char 10 200 or (with DevFS) a symlink to ../misc/net/tun (not misc/net/tun): No such device vpnc-connect: can't initialise tunnel interface: No such device
However when I check for the tun device I get
root@t............:~# ls -l /dev/net/tun crw------- 1 root root 10, 200 2012-11-02 01:49 /dev/net/tun
This is Ubuntu 10.04 32bit running on a VPS with tun/tap enabled. I had to ask the administrator to enable it.
