Subject: socket in Ruby

Hi,

i'm working n the pleac web site (pleac.sourceforge.net). The idea of this
web site is to have a "cook book" (like the perl's one) for a lot of
languages.

I'm trying to wrote the Ruby's part about sockets.
But i've failed to find an easy way to use low level socket API.
For example for the folowing Perl code:
-----------
socket(TO_SERVER, PF_INET, SOCK_STREAM, getprotobyname('tcp'));

# build the address of the remote machine
$internet_addr = inet_aton($remote_host)
    or die "Couldn't convert $remote_host into an Internet address: $!\n";
$paddr = sockaddr_in($remote_port, $internet_addr);
# connect
connect(TO_SERVER, $paddr)
    or die "Couldn't connect to $remote_host:$remote_port : $!\n";
-----------
i've wrote the folowing ugly Ruby code:
-----------
s=Socket.new(Socket::AF_INET, Socket::SOCK_STREAM, 0)
# build the address of the remote machine
sockaddr_server=[Socket::AF_INET, 80,
  Socket.gethostbyname('www.ruby-lang.org')[3], 0, 0
  ].pack("snA4NN")
#connect
begin
 s.connect(sockaddr_server)
rescue
 print "error: #{$!}\n"
end
-------------

How can i manage low level socket without this 'pack("snA4NN")' ?


Regards
