Minimal remote webserver test.

Using sh and telnet magic.

Workmate of mine had to resort to perl. I was sure it could be done with just a sh-script. I was right. What a beauty. Copy & Paste below or go to pastebin.

#!/bin/sh
timeout=10
tracefile=telnettrace
HOST=$1

telnet_commands() {
tout=${timeout}
echo open $1 80

sleep 1

while [ "$tout" -ge 0 ]
do
if tail -1 $tracefile 2>/dev/null | grep "character" > /dev/null
then
echo "HEAD / HTTP/1.0\n"
tout=-15
continue
else
sleep 1
tout=$[$tout-1]
fi
done
tout=${timeout}
while [ "$tout" -ge 0 ]
do
if tail -1 $tracefile 2>/dev/null | grep "^$" > /dev/null
then
tout=-15
continue
else
sleep 1
tout=$[$tout-1]
fi
done
}

telnet_commands $HOST | telnet |tee $tracefile
