Connect at Ircam with OpenVPN

(disponible en français)

Preliminary notes

Last revision : v14

You will find 2 OVPN files :

Always pick the first one. In somes cases, it will fail. It's due to network AND operating system combined so it's possible that the configuration work (or not) and then stop (or begin) working when moving. If it fails, uses the "reduit" ("reduced") version.

If you pick the "reduit" version but the normal version should work, you may have some random disfonctions in your network.
