Hi, I would like to consult regarding this issue of OpenVPN I installed using CentOS. I followed this link in setting up OpenVPN http://www.howtoforge.com/openvpn-server-on-centos-5.2. I completely followed the instructions. However there is an issue after installing the OpenVPN. When I tried to start OpenVPN using this command with a root access. #/etc/init.d/openvpn start* *I received failed error. And when i try to see the logs. I found out this error. "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" I try to search solution using google. But I am failed. So I decided to send an email to you to help me with this problem of mine. Please send me a guide or steps how to solve the problem Respectfully Yours, Joselito E.

do (as root) modinfo tun modprobe tun if the second command returns an error , then there's something wrong with your CentOS installation ; after the 'modprobe' do an lsmod | grep tun to see if the device is actually listed.

The command most likely worked fine.

If you config uses: dev tun0 Then this will cause this error. Try changing that to either: dev tun or to: dev tun1 If you use the former (dev tun), OpenVPN will take the first available "slot". So if tun0 is in use, it will try tun1, tun2, tun3, etc until it finds a suitable tun device. The second error can be a bit misleading, but this is OpenVPN trying to use an different approach to create the tun device, for older Linux kernels. This error you can simply ignore.
