I use LWP::Simple to get responses from remote sites. If the site responds, all is well. If there is a DNS problem (e.g. the URL is wrong) all is also well - the get fails in a timely manner. But if the remote site is down and simply not responding, is there any way to tell?
A search on the monastery suggests it cannot be done with LWP - the script simply hangs awaiting a response - even if you adjust the timeout settings. Does anyone know any other way? (Or is the problem with Linux or Apache rather than LWP or Perl?)

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).
