Ant and Ping Question

[Z W]

Hi Gurus

Is there a jar file out there that provides ping task to verify if a host
connection is working ?

Another approach I have is to use cgwin with ant

<
exec dir=" ." executable= "cygwin.bat" os= "Windows XP" timeout ="1000"
failonerror ="true">
<
arg line=" _build_ping_alive.sh"/>
</
exec>


_build_ping_alive.sh
===============
#!/usr/bin/bash
ping linpacdb1 -t 1 | sed '1,4d' | grep -o 100.0
ping linpacdb1 -t 1 | sed '1,4d' | grep -o 0.0

But I'm still getting no/wrong output.
     [exec] ←]0;~
     [exec] [EMAIL PROTECTED] ←[33m~←[0m
     [exec] $ logout
What am I doing wrong ?
Any help is appreciated.
