general

here is a small script that can be used by bsd/linux/*nix boxes to start/stop mlnet.
the stop stdout output is not quite clean, but it functions.

requirements

1. . the http interface must be enabled for localhost.
   
2. . gnu wget
   
3. . striphtml.sed script (see below)
   

mlnet.sh

#!/bin/bash

# STRIP_SCRIPT="$MLNET_DIR/scripts/striphtml.sed"
HTTP_PORT="4080"

echo  -n ' mlnet '

case "$1" in
start)
        echo start
#        cd $MLNET_DIR
        $MLNET_COMMAND
        ;;

        echo stop
        wget -q --spider --http-user=admin --http-password='!n@\033[m' \
                   "http://localhost:$HTTP_PORT/submit?q=kill"

alternative way to get status

You either can grab status without the external sed script and without wget:

status)

       echo -e \"auth $password\nbw_stats\nquit\" || nc -w 1 127.0.0.1 4000 ||grep ^D
       ;;
