however, as I did not want to give the docker container full privileged access, I tried a little around and finally figured: it works if you also add the /dev/net/tun device: cheers, --- KD in menuconfig AdvThanksance! ;) …Mike -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mike Dickson Sent: April 15, 2004 1:36 PM To: [email protected] Subject: [Openvpn-users] openVPN can't find My openvpn implementation was working well until I rebooted this morning and I'm experiencing this issue.Mon Mar 18 15:02:22 2013 us=742824 OpenVPN 2.2.1 i686-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] [eurephia] [MH] [PF_INET6] Error: Cannot Open Tun/tap Dev /dev/net/tun: Operation Not Permitted (errno=1) Join Date Dec 2005 Posts 13 Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19) Hi guys, I have installed openVPN in my redhat 8 linux box.
Now you can run nearly all the common unsecured daemons (I'm paranoid) on the VPN ip addresses! Host OS is an archlinux LTS up to date. Reason(s): No reason supplied.

Cat: /dev/net/tun: Operation Not Permitted But I ended up with a tun1 instead of a tun0. TUN is compiled into all our modern kernels. "zgrep TUN /proc/config.gz" to see. I occasionally have to build an openvpn box and each time I find that I have to "read up" on the same items!
Do I need to recompile the kernel with support for the tun/tap module or is there an easier, less time consuming way of getting module installed in the kernel?? So you may understand that using commercial certificates like Thawte's really isn't an option in our case!

ANY COMMENTS would be appreciated! I asked about it in IRC; and someone mentioned the udev possibility. Not a member yet? Tun: Unknown Symbol __sk_attach_filter Reload to refresh your session.
In my case it was fixed by runningCode:sudo udevadm triggerThere was no need to manually create the /dev entry.Sorry for posting on a old thread. You can use the secret key file and the certificate encryption at the same time.

I suggest we start right away and get this all out of the way quickly.:) If you are using version 2.3.0, please note that the easy-rsa scripts have been put into So if you used the certificate method, you can also do the alternative step down here to keep your network even more secure!
Run the installer on default setup. After a program closed abovedevices, driver will automatically delete tunXX or tapXX device andall routes corresponding to it. Further more you can "dial in" when you need access to the VPN network, multiple clients can connect to the server too. I am on Ubuntu 12.04 LTS (32 bit).

Here are my details...2.4.21-4.ELsmp Straight to the point...My linux skills are a little wavy but I can get around happily, most of the time...BUT, I need assistance loading the tun/tap module.
Xen Platform Please ensure you have installed the kernel modules which your software requires to use the TUN/TAP device. The .key files are the only ones that shouldn't be left unprotected as it's the only part that's private. My OpenVPN TUN server was working fine, until I rebooted to pick up kernel 3.7.10. Join Date Oct 2004 Location Johannesburg, South Africa Posts 3 OpenVPN and tun/yap module Hi All, 3 years on from the original posting I have come across the very same problem.
Could this be a linode kernel issue or perhaps related to an Ubuntu 12.04 update? I just found this thread while trying to solve the same issue. You signed in with another tab or window. Ignore all that though because I'd be almost certain you have the module available already.
