As what have you said, If there is no error the tun module is probably is
running and ready to use. However the main problem of mine is the OpenVPN
itself when I tried to run It failed and when I try to see the logs.
This is what I found in the error log;
*
"Tue May 31 09:58:43 2011 us=705749 Note: Cannot ioctl TUNSETIFF tun0:
Device or resource busy (errno=16)
Tue May 31 09:58:43 2011 us=705763 Note: Attempting fallback to kernel 2.2
TUN/TAP interface
Tue May 31 09:58:43 2011 us=705787 Cannot open TUN/TAP dev /dev/tun0: No
such file or directory (errno=2)
Tue May 31 09:58:43 2011 us=705811 Exiting"*

What I need to know how to solve this problem Since we all know the module
of tun is running, Any other possible reason why I commit that error? If
there is so How can I do such solution? Your help is a great appreciated.
