I am trying to setup OpenVPN on one VPS using the "dummy0" trick as described at http://forum.openvz.org/index.php?t=msg&th=315 , in the wiki and some other sources.
However, when I run "openvpn --mktun --dev tap0" I get this error:
Thu Oct 18 14:04:59 2007 TUN/TAP device tap0 opened
Thu Oct 18 14:04:59 2007 Note: Cannot set tx queue length on tap0: Operation not permitted (errno=1)
Thu Oct 18 14:04:59 2007 Cannot ioctl TUNSETPERSIST(1) tap0: Operation not permitted (errno=1)
Thu Oct 18 14:04:59 2007 Exiting
/dev/tun exists. I can also create tap0 manually but that didn't help either. Both tun & bridge modules are loaded on the host.
Thanks in advance for any help
