Hi I need a feature "connection on demand" including a "callback" script for a tls-client. why? I want to connect two servers via internet and establish a tunnel. Both servers use ADSL to connect to the internet on demand. Now if one server wants to connect to the other, he has to inititate a callback (in my case call the other via ISDN/capiutils wich in tune connects to the internet) After this, the openvpn connection will run as normal.
With the --demand feature set, the client should set up its devices and routes as to the config file like normal, but should not connect to the host named in --remote until the first packet has to be transmitted. Using the --callback feature, openvpn should call a script or plugin before initiating the --remote connection. This script or plugin can then start a dialup link or do some other things to get a connection to the --remote host. I looked at the sources to do this myself, but hacking is hard to start. Can you help me on where to look? bye Ulf
