openvpn fails to start

[tud2007]

Hello,

openvpn cannot start on vu+ uno4k with obenbh 4.4 and ends with the following messages:

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19)
Exiting due to fatal error

/var/log/messages has then this line: tun: Unknown symbol nf_conntrack_destroy (err 0)

it also ends sometimes with this error, after a few tries again same error with tun
UDP: Cannot create UDP/UDP6 socket: Address family not supported by protocol (errno=97)

This fix and reinstalling the modules didn't help either.

# mkdir /dev/net
# mknod /dev/net/tun c 10 200
# modprobe tun
modprobe: ERROR: could not insert 'tun': Unknown symbol in module, or unknown parameter (see dmesg)

any known issue ?

as suggested in another forum, this solved the problem

opkg update
opkg install --force-reinstall kernel-image-3.14.28-1.12

then reboot

Do you know which version of OpenVPN is being used in openbh 4.4.x?
I currently have openbh 4.3.039 installed and that came with OpenVPN 2.3.x. I had to manually patch it to 2.4.x to make it work with my provider.

Thanks!
