====== Install OpenVPN in lxc ======

<WRAP center round important 60%>
On Debian 9 Stretch host create these files for Debian 7 Wheezy container

  mkdir /dev/net
  mknod /dev/net/tun c 10 200
</WRAP>

Follow tutorial at https://web.archive.org/web/20220927084048/https://openvpn.net/community-resources/how-to/

  apt-get install openvpn

In server.conf plugin path for user/pass authentication:

  plugin /usr/lib/openvpn/openvpn-auth-pam.so system-auth

For Jessie (Debian 8):

  plugin /usr/lib/openvpn/openvpn-plugin-auth-pam.so system-auth

In case of error:

  Mon Dec 18 14:48:14 2017 srv02/xxx.xxx.x.x:39658 Authenticate/Decrypt packet error: cipher final failed

make sure the ciphers are same in //server.conf// and //client.conf//.

For unprivileged container inside Proxmox for mknod to work add this to ///etc/pve/lxc/lxc.conf//:

  lxc.mount.entry = /dev/net dev/net none bind,create=dir

Also check owner of files on host vs container.
