If it's a shared hosting server that lets you upload Ruby scripts, then I
don't suppose they could stop you uploading or compiling your own copy of
zlib (or if the compilers have been removed, uploading your own copy of gcc
first :-)

If you don't have shell access, try uploading this:

  #!/usr/local/bin/ruby
  require 'cgi'
  c = CGI::new
  print c.header
  puts "Enter command: <form method=get><input type=text name=command></form>"
  if c['command'][0]
    puts "<pre>"
    $stdout.flush
    system "#{c['command'][0]} 2>&1"
    $stdout.flush
    puts "</pre>"
  end

Suggestion: use .htaccess to prevent the whole world seeing this script, if
you don't want to incur your webmaster's wrath...

Cheers,

Brian.
