in thread using jabber for RPC or inter-server-communication

thanks but no - pppd with the 'demand' option sets up a virtual interface that is 'up' so that applications don't notice that it actually isn't, and then buffers packets, connects, and spurts them out as soon as the connection REALLY is up...
this is really weird. but then again, i think i saw an option with which you can set which packets bring up the interface, and which don't so maybe if i put ICMP in that thing, i can simply use ping....ah well. let's see.
thnaks, again...

    thanks but no - pppd with the 'demand' option sets up a virtual interface that is 'up'

    But you can easily see that, because the configured IP adress is a private or invalid (depends on pppd and the configuration, on my gateway it'a a 192.168.) one, while it surely isn't once a connection is established. So checking the ifconfig output, conviniently done using Net::Ifconfig::Wrapper, check the ip-adress for validity/privateness and your done.

    they will find an easier way to do it.

      huh? really? i assigned private IPs to those virtual interfaces anyhow, so i wouldn't have noticed...but wouldn't assigning a private IP (with a route to it) to the virtual interface not destroy the whol reason for actually having that virtual interface?
      i mean - how would the packets that are supposed to go out on that link know how to go that link?
      thanks, though - i'll look for some documentaion for that...
