Forking does not seem to be the optimal solution to this.
I would prefer to set a handler for SIGALRM and set an
alarm, something like.
$SIG{ALRM} = sub { die ("Couldn't traceroute"); };
alarm (20);
if ($tracert = `traceroute "$ip"`)
{
alarm (0);
}
# handle data from traceroute here
This is documented in the perlipc perldoc.
1. dude, what does mine say?
2. "sweet", what about mine?
3. "dude", what does mine say?
4. GOTO 2

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
