Hi,
I am trying to write a script which reads data from a GZip compressed network stream.
The first byte is defined as a "Z" - the following data is then ziped.
My current attempt looks as follow:
my $s=new IO::Socket::INET(PeerAddr => "$server", PeerPort => $port );
print $s "C\n";#ask for the challenge
my $chall;
my $status;
my $status=$s->recv($temp, 1);
$status=$s->recv($temp, 1024);
$chall=Compress::Zlib::uncompress($chall);
Unfortunately $chall is always undef indicating a compression error.
Given the sizes of $temp and $chall, I am already not sure about the reading of the data from the network for binary data - I have used recv sofar only with text - does recv also work for binary data? What is the correct way to decompress a GZip stream?

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
