Quick snippet I threw together to get the status of a ventrilo server. I was unable to directly query a server because of the semi-proprietary way you have to ask for the status, instead I used a xmlish feed from an outside webhost.

To use, just make a variable %vent with ip:port

Have fun.

UPDATED Sunday, July 12, 2009

Added a GUI vent status thing, its rough, not much error check just enough to show what could be done. I will also need to work out a way to sort by channels CID parameter rather than alphabetic to get a more accurate representation of the server layout.
Usage: /ventg ip:port

alias ventc {
  sockopen ventc ventrilostatus.net 80
  sockmark ventc $1-
  .timervent 1 3 vent_timeout
}

alias vent_timeout {
  var %msg = $gettok($sock(vent).mark,2,32)
  msg %msg Sorry, but the server took to long to respond or is down. Try again later.
  sockclose vent
}

alias ventg {
  sockopen ventg ventrilostatus.net 80
  sockmark ventg $1
}

on *:SOCKOPEN:vent*:{
  If ($sockerr) { echo error | halt }
  sockwrite -n $sockname GET /xml/ $+ $gettok($sock($sockname).mark,1,32) $+ / HTTP/1.1
