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
