As some of you know, I use Hamster, a free news server with many other options. I also use Hamster to download all postings on different groups on Yahoo. This is great when there is so much traffic in a group and so much I would like to keep. It fetches the postings and puts them nicely into a local newsgroup here on my computer so that I can use my normal news reader to read everything. It sorts them into subjects and all, and I can do the much more likable searches that I can do from my news reader. If you ever have tried searching for a post in groups.yahoo you know what I mean.

Here is the Perl script I use to download into my news server:

#!/usr/local/bin/perl

# $Header: E:/RCS/yahoo.pl 1.4 2001/05/16 21:14:34 prupe Exp prupe $

use HTML::Entities;
use HTTP::Request;
use HTTP::Headers;
use LWP::UserAgent;
use Win32::OLE;


sub logf (@)
{
  return if (!$opt{debug});
  print STDERR "---Main: ";
  printf STDERR @_;
  print STDERR "
";
}

sub get_url ($)
{
  my $url = $_[0];
  my ($host, $h, $req, $ua);

  $host = $url;
  $host =~ s,^w+://,,;
  $host =~ s,/.*,,;

  $h = HTTP::Headers->new;
  $h->user_agent($USERAGENT);
  $h->referer("http://$host/");
  $h->header('Host' => $host);
  $h->header('Connection' => 'close');
  $h->header('Accept' => '*/*');
  $h->header('Accept-Lanugage' => 'en');
  $h->header('Cookie' => $COOKIE);
  print ($h->as_string) if ($opt{debug});

  $req = HTTP::Request->new('GET' => $url, $h);
  $ua = LWP::UserAgent->new;
  return $ua->request($req);
}


%opt = ( );
foreach $a (@ARGV)
{
  ($opt{debug} = 1, next) if ($a eq "-l");
  ($STARTINGNUM = 0 + $a, next) if (!$STARTINGNUM);
  ($ENDINGNUM = 0 + $a, next) if (!$ENDINGNUM);
}

$USERAGENT = 'SpaceBison/0.01 [fu] (Win67; X; ShonenKnife)';
$URLPATTERN = 'http://groups.yahoo.com/group/prox-list/message/%d?source=1';
$STARTINGNUM = 1 if (!$STARTINGNUM);
$ENDINGNUM = 6436 if (!$ENDINGNUM);
# !!!! IMPORTANT !!!!
#
# This script uses several Perl 5 modules.  Make sure they are in your Perl
# library path.  SET PERL5LIB=E:PERLLIB;E:PERLLIBPOD works for me.
# After that, the command
#   perl yahoo.pl <starting num> <ending num>
# should work.  Messages that Hamster fails to import for some reason will be
# dumped to failed.txt in the current directory.
#
# Edit the following lines before running this script or it will not work.
# $COOKIE: Use your Yahoo login cookie here.  To find this go to
#   http://groups.yahoo.com/group/prox-list/ with Prox's log window open.
#   Look for the line in the outgoing headers that starts with "Cookie:".
#   Copy the entire line except for the text "Cookie: " to the variable
#   assignment below.
# $NEWSGROUP: Whatever newsgroup in Hamster you want to import the messages
#   into.  I use pr.proxomitron.archive, but this is arbitrary.
$COOKIE = 'HERE';
$NEWSGROUP = 'pr.proxomitron.archive';
';

$COOKIE =~ s/^Cookie:s*//;
if (!$COOKIE)
{
  print "You must set the variable $COOKIE in $0

  print "See the section labeled IMPORTANT

  exit 1;
}

$hamster = Win32::OLE->new("Hamster.App");

Nice looking script, I'll have to give it a go.
