OpenVPN service start error; perhaps kernel problem

carcass09

Here is the error message upon attempting to start the OpenVPN service:

[ ok ] Stopping virtual private network daemon:.
[ .... ] Starting virtual private network daemon: client serverSIOCSIFADDR: No such device
: ERROR while getting interface flags: No such device
SIOCSIFDSTADDR: No such device
: ERROR while getting interface flags: No such device
SIOCSIFMTU: No such device
 failed!

I am on a *virtual* Debian (wheezy- Release 7.5) machine.
My server configuration settings are as follows, server.conf:

port 1194
proto udp
dev tun

ca ca.crt
cert server.crt
key server.key

dh dh1024.pem

server 10.8.0.0 255.255.255.0
ipconfig-pool-persist ipp.txt

keepalive 10 120

comp-lzo
user nobody
group nobody

persist-key
persist-tun

status openvpn-status.log

I have done a lot of google searches to solve my problem but to no avail.
'modprobe tun' returns:

libkmod: ERROR ../libkmod/libkmod.c:505 kmod_lookup_alias_from_builtin_file: could not open builtin file '/lib/modules/2.6.32-042stab075.2/modules.builtin.bin'
FATAL: Module tun not found.

I am a beginner so please do not overlook the obvious solution!

ThankYou

Thank you for your reply.

It is a service I pay for monthly, a VPS.

The two things you suggest do not help; after I make the device, 'modprobe tun' returns the following error message:

libkmod: ERROR ../libkmod/libkmod.c:505 kmod_lookup_alias_from_builtin_file: could not open builtin file '/lib/modules/2.6.32-042stab075.2/modules.builtin.bin'
FATAL: Module tun not found

Ok thanks.
I believe you're right, this is what my friend suggested too.

I have found the client configuration area. It is a 'Virtualmin' system. But I cannot see TUN/TAP anywhere. Is there something other setting which I should look out for?

BIND DNS Server Stopped Start
Postfix Mail Server Stopped Start
Dovecot IMAP / POP3 Server Stopped Start
