Just a basic easy firewall that asks for permission if a script wants to access the internet. You only need to put it in your remote.

alias sockopen {
  var %address = $+($gettok($1-,-2,32),$chr(58),$gettok($1-,-1,32)), %action = $readini(firewall.ini,firewall,%address)
  var %permitmessage = echo 3 -s %address making contact with the internet!, %blockmessage = echo 4 -s %address blocked!
  %action = $iif(%action,%action,0)
  goto %action

  ;Action 0: Ask to open
  :0 | var %a = $?!="Allow %address to be opened?", %b = $?!="Always use this action for %address ?"
  if (%b) writeini firewall.ini firewall %address $iif(%a,1,2)
  if (%a) { %permitmessage | !sockopen $1- } | else %blockmessage
  return

  ;Action 1: Permit
  :1 | %permitmessage | !sockopen $1- | return

  ;Action 2: Block
  :2 | %blockmessage | halt
}

/*
This script can be upgraded in many many ways (it can still be avoided). Well heres already a small upgrade. It isnt really necessarry but what it does is when you load a script file it does an easy search for sockopen commands and if it finds 1 asks if you want to load the file anyway:

alias load {
