Re: Do shell script question - timeouts

mdns doesn't stop.  It keeps running.  

Even if I remove the redirects, control is never returned from the shell

Try this:

on run
        set myShellString to "mdns -B _afpovertcp._tcp. local"
        do shell script myShellString
end

Don't forget to killall mdns afterwards.

I just got an idea to have a little instant simple sharing between all my 
machines since iChat file transfer fails on 1/2 of my Macs now and I've got 
enough 10.6.x macs that Airdrop is not a solution.

Just want to instantly discover all the AFP macs on the network, check for a 
volume on it that is hostname - Share, log on to it and drop off a file, then 
dismount.  A simple file send to the other Mac in my list.

It's a little project I might have time to get together and this might be fun.
