Use the error method to see if some error happened.
for my $host (...) {
$ssh{$host} = Net::OpenSSH->new($host, ...);
if($ssh{$host}->error) {
print STDOUT "Still waiting for SSH. Retrying in 5 seconds...\
+n";
sleep 5;
redo;
}
else {
print STDOUT "SSHD is back up. Continuing...\n";
}
}
If you are starting several connections in parallel, you can also use the wait_for_master method.

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).
