(OP)
Hi to all,
  I have written a perl script to execute some command, like Tracert, and would like to improve it by including a time out function. This is in case Tracert hangs or something else happens. Any idea how I can go about doing it?

  Thanks for the suggestions.

cheers,
Just Me!!

RE: timeout

Take a look at the alarm command.  But, remember, it seems to only function well on a logical block (i.e. eval).

We use the following to do exactly what you are asking for in our internet home banking i/o logic:

eval {
local $SIG{ALRM} = sub {die "alarm\n" };
alarm(10);
local $/=undef;
.
.
.
alarm(0);
};

You can even make the argument sent to alarm a variable so the wait time can differ from function to function.

This seems to work well.  Good luck.
