OK - This is a quick & dirty hack - I'm sure there are several more
elegant
solutions... But it works.  NOTE: this is designed for a Shoutcast server.
You'd need to change the check=  lines to work with Icecast.  Couldn't
find
an Icecast-specific copy, since I'm only using Shoutcast servers currently.

2 files:

#!/bin/bash
# Keepalive for liveice encoder
# bill@radioparadise.com
#

LOG=/usr/local/icecast/ka.log
SERVER=scastsrv2.shoutcast.com:8048
DIR=icecast
STREAM=RP128
STARTFILE=/usr/local/icecast/restart.128

echo "`date` - Keepalive started for $STREAM" >> $LOG
while [ 0 ]
do
check=`lynx -dump http://$SERVER/index.html  | grep -c "currently
down"`
if [ $check = 1 ]
then
$STARTFILE
echo "`date` - $STREAM restarted" >> $LOG
sleep 10
check=`lynx -dump http://$SERVER/index.html  | grep -c "currently
down"`
if [ $check = 1 ]
then
echo "`date` - Bummer. $STREAM on $SERVER is down" >> $LOG
else
echo "`date` - Yippee! $SERVER sez Stream Is Up!" >> $LOG
fi
# else
# echo "`date` - $STREAM on $SERVER OK"  >> $LOG
fi
sleep 20
done

[sample $STARTFILE]

#!/bin/bash

DIR=icecast

kill `/usr/local/icecast/ps xww | grep "$DIR/lame" | cut -c1-5`
>/dev/null
kill `/usr/local/icecast/ps xww | grep "$DIR/liveice" | cut
-c1-5`
>/dev/null
/usr/local/$DIR/liveice >/dev/null 2>/dev/null &

I'd love to take a look at this script, and, more than likely, I'm not
the only one :)

Please post an example.

ok...based on William's shoutcast-based suggestion, i've come up with
the following. i haven't had time to really test the thing
yet...suggestions are greatly appreciated.

i based this on the fact that icecast's stats.log tells what sources are
connected (in my case 0 and 1) and that log is updated frequently (per
icecast.conf)

#!/bin/sh

DIR=/usr/local
LOG=$DIR/var/icecast/log/stats.log
SOURCE=`cat $LOG |grep Source\ [0-1] |awk '{print $1"
"$2}'|sort |uniq`
PIDS=`ps ax |grep $DIR/bin/liveice |awk '{print $1}' ; ps ax |grep
$DIR/bin/lame |awk '{print $1}'`

if [ "$SOURCE" ] ; then
        echo "LiveIce still connected to icecast server."
else    
        if [ "$PIDS" ] ; then 
                echo "Killing rogue processes..."
                echo "pid(s): $PIDS"
                kill -9 $PIDS
                $DIR/bin/liveice -F
$DIR/etc/liveice/liveice.cfg
>/dev/null 2>/dev/null &
                echo "LiveIce restarted at `date`."
        else
        $DIR/bin/liveice -F $DIR/etc/liveice/liveice.cfg >/dev/null
2>/dev/null &
        echo "LiveIce restarted at `date`."
        fi
fi
