Wget Gateway

Welcome to Wget Gateway, a simple page showing the usage of socksified wget behind a firewall. In my configuration it is very useful because:

• Only few users can exit from firewall
• A lot of users need information that can be reached in Internet
• I cannot dowload big files during my job time, so, I have to schedule the requests after the normal work time

With the combination of a socksified wget and a simple cgi that schedules the requests can I reach the aim. All you need is:

• A socksified copy of wget
• Perl (available on all the GNU mirroring sites)
• cgi-lib.pl (available at CPAN)
• A customized copy of this html
• A customized copy of socks.cgi

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.:

• download.html requires wget.cgi
• wget.cgi requires Perl, cgi-lib.pl and wget
• 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 htceff, 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).

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
