Hi,
I am trying hard to install openvpn inside a VE, but until now I had no success.
In detail:
I followed this HOWTO:
http://wiki.openvz.org/VPN_via_the_TUN/TAP_device
TUN is loaded on HN:
| Quote: |
# lsmod | grep tun
tun 7136 0
|
VE is authorized to use tun/tap, device is installed on VE
| Quote: |
# vzctl set 1001 --devices c:10:200:rw --save
# vzctl exec 1001 mkdir -p /dev/net
# vzctl exec 1001 mknod /dev/net/tun c 10 200
# vzctl exec 1001 chmod 600 /dev/net/tun
|
openvpn ist compiled, installed, and configured on VE, but the attempt to start openvpn fails:
| Quote: |
~# openvpn --config /etc/openvpn/server.conf

What's going wrong here? Why does openvpn get no access (user root has same result)
Thanks for any idea!
Best regards
Burkhard

Well, the solution seems to be obvious.
Of course the tun device has to be activated on the HN before giving access to the VE.
So first on HN:
| Quote: |
# mkdir -p /dev/net
# mknod /dev/net/tun c 10 200
# chmod 600 /dev/net/tun
|
and after that on VE
| Quote: |
# vzctl set 1001 --devices c:10:200:rw --save
# vzctl exec 1001 mkdir -p /dev/net
# vzctl exec 1001 mknod /dev/net/tun c 10 200
# vzctl exec 1001 chmod 600 /dev/net/tun
|
Now everything works!
Burkhard
