<h1>Wget Gateway</h1>
|
|
|
|
|
<p>
|
|
|
|
|
Welcome to Wget Gateway, a simple page showing the usage of
|
|
|
|
|
socksified wget behind a firewall. In my configuration it is
|
|
|
|
|
very useful because:
|
|
|
|
|
<ul>
|
|
|
|
|
<li>Only few users can exit from firewall
|
|
|
|
|
<li>A lot of users need information that can be reached in Internet
|
|
|
|
|
<li>I cannot dowload big files during my job time, so, I
|
|
|
|
|
have to schedule the requests after the normal work time
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
With the combination of a socksified wget and a simple cgi
|
|
|
|
|
that schedules the requests can I reach the aim. All you need
|
|
|
|
|
is:
|
|
|
|
|
<ul>
|
|
|
|
|
<li> A socksified copy of
|
|
|
|
|
<a href="ftp://gnjilux.cc.fer.hr/pub/unix/util/wget/wget.tar.gz">
|
|
|
|
|
wget</a>
|
|
|
|
|
<li> Perl (available on all the GNU mirroring sites)
|
|
|
|
|
<li> cgi-lib.pl (available at
|
|
|
|
|
<a href="ftp://ftp.switch.ch/mirror/CPAN/ROADMAP.html">CPAN</a>)
|
|
|
|
|
<li> A customized copy of this html
|
|
|
|
|
<li> A customized copy of socks.cgi
|
|
|
|
|
</ul>
|
|
|
|
|
This is my h/s configuration:
|
|
|
|
|
<pre>
|
|
|
|
|
|
|
|
|
|
+----------+ +----------------------------------+ +---------------------+
|
|
|
|
|
| Firewall | | Host that can exit from firewall | | Intranet www server |
|
|
|
|
|
+----------+ | htceff | +---------------------+
|
|
|
|
|
+----------------------------------+ | Wget.html |
|
|
|
|
|
| socksified wget | +---------------------+
|
|
|
|
|
| cgi-lib.pl |
|
|
|
|
|
| perl |
|
|
|
|
|
| wget.cgi |
|
|
|
|
|
+----------------------------------+
|
|
|
|
|
</pre>
|
|
|
|
|
<p>
|
|
|
|
|
wget.cgi, wget and cgi-lib.pl are located in the usual
|
|
|
|
|
cgi-bin directory. The customization of wget.cgi and
|
|
|
|
|
wget.html has to reflect you installation, i.e.:
|
|
|
|
|
<ul>
|
|
|
|
|
<li> download.html requires wget.cgi
|
|
|
|
|
<li> wget.cgi requires Perl, cgi-lib.pl and wget
|
|
|
|
|
<li>
|
|
|
|
|
wget.cgi has to download the files to a directory writable
|
|
|
|
|
by the user submitting the request. At the moment I have an
|
|
|
|
|
anonymous ftp installed on <em>htceff</em>, and wget puts
|
|
|
|
|
dowloaded files to /pub/incoming directory (if you look at
|
|
|
|
|
wget.cgi, it sets the destdir to "/u/ftp/pub/incoming" if
|
|
|
|
|
the user leaves it blank).
|
|
|
|
|
</ul>
|
|
|
|
|
<p>
|
|
|
|
|
You can also add other parameters that you want to pass to wget,
|
|
|
|
|
but in this case you will also have to modify wget.cgi
|

<h3>Downloading (optionally recursive)</h3>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
Recursion:
|
|
|
|
|
<Select name=Recursion>
|
|
|
|
|
<Option selected value=N>No</Option>
|
|
|
|
|
<Option value=Y>Yes</Option>
|
|
|
|
|
</Select>
|
|
|
|
|
<li>
|
|
|
|
|
Depth:
|
|
|
|
|
<input type="radio" name=depth value=1 checked>1
|
|
|
|
|
<input type="radio" name=depth value=2 >2
|
|
|
|
|
<input type="radio" name=depth value=3 >3
|
|
|
|
|
<input type="radio" name=depth value=4 >4
|
|
|
|
|
<input type="radio" name=depth value=5 >5
|
|
|
|
|
<li>
|
|
|
|
|
Url to download: <input name="url" size=50>
|
|
|
|
|
<li>
|
|
|
|
|
Destination directory: <input name="destdir" size=50>
|
|
|
|
|
</ul>
|
|
|
|
|
Now you can <input type="submit" value="download"> the
|
|
|
|
|
requested URL or <input type="reset" value="reset"> the form.
