|
|---|
| 10 | <p>
|
|---|
| 11 | Welcome to Wget Gateway, a simple page showing the usage of
|
|---|
| 12 | socksified wget behind a firewall. In my configuration it is
|
|---|
| 13 | very useful because:
|
|---|
| 14 | <ul>
|
|---|
| 15 | <li>Only few users can exit from firewall
|
|---|
| 16 | <li>A lot of users need information that can be reached in Internet
|
|---|
| 17 | <li>I cannot dowload big files during my job time, so, I
|
|---|
| 18 | have to schedule the requests after the normal work time
|
|---|
| 19 | </ul>
|
|---|
| 20 |
|
|---|
| 21 | <p>
|
|---|
| 22 | With the combination of a socksified wget and a simple cgi
|
|---|
| 23 | that schedules the requests can I reach the aim. All you need
|
|---|
| 24 | is:
|
|---|
| 25 | <ul>
|
|---|
| 26 | <li> A socksified copy of
|
|---|
| 27 | <a href="ftp://gnjilux.cc.fer.hr/pub/unix/util/wget/wget.tar.gz">
|
|---|
| 28 | wget</a>
|
|---|
| 29 | <li> Perl (available on all the GNU mirroring sites)
|
|---|
| 30 | <li> cgi-lib.pl (available at
|
|---|
| 31 | <a href="ftp://ftp.switch.ch/mirror/CPAN/ROADMAP.html">CPAN</a>)
|
|---|
| 32 | <li> A customized copy of this html
|
|---|
| 33 | <li> A customized copy of socks.cgi
|
|---|
| 34 | </ul>
|
|---|
| 35 | This is my h/s configuration:
|
|---|
| 36 | <pre>
|
|---|
| 37 |
|
|---|
| 38 | +----------+ +----------------------------------+ +---------------------+
|
|---|
| 39 | | Firewall | | Host that can exit from firewall | | Intranet www server |
|
|---|
| 40 | +----------+ | htceff | +---------------------+
|
|---|
| 41 | +----------------------------------+ | Wget.html |
|
|---|
| 42 | | socksified wget | +---------------------+
|
|---|
| 43 | | cgi-lib.pl |
|
|---|
| 44 | | perl |
|
|---|
| 45 | | wget.cgi |
|
|---|
| 46 | +----------------------------------+
|
|---|
| 47 | </pre>
|
|---|
| 48 | <p>
|
|---|
| 49 | wget.cgi, wget and cgi-lib.pl are located in the usual
|
|---|
| 50 | cgi-bin directory. The customization of wget.cgi and
|
|---|
| 51 | wget.html has to reflect you installation, i.e.:
|
|---|
| 52 | <ul>
|
|---|
| 53 | <li> download.html requires wget.cgi
|
|---|
| 54 | <li> wget.cgi requires Perl, cgi-lib.pl and wget
|
|---|
| 55 | <li>
|
|---|
| 56 | wget.cgi has to download the files to a directory writable
|
|---|
| 57 | by the user submitting the request. At the moment I have an
|
|---|
| 58 | anonymous ftp installed on <em>htceff</em>, and wget puts
|
|---|
| 59 | dowloaded files to /pub/incoming directory (if you look at
|
|---|
| 60 | wget.cgi, it sets the destdir to "/u/ftp/pub/incoming" if
|
|---|
| 61 | the user leaves it blank).
|
|---|
| 62 | </ul>
|
|---|
| 63 | <p>
|
|---|
| 64 | You can also add other parameters that you want to pass to wget,
|
|---|
| 65 | but in this case you will also have to modify wget.cgi
