Video server is a streaming video server which feeds a Java applet/application for display. The updates are rather slow, somewhere in the 10 frames/second range on a PIII. The server is written in Bigloo scheme and C. The client is written in Java.

To bring up the video server you have to do the following.

./vs --channel 25 --sd 12 --input 0

./vs --help
for more options. (This seems broken with the newest version of bigloo .... )

How to bring up a java client to connect to a server:
Insure that video/java is in your classpath, and invoke

java vpanel servername

GSTorrent is a Bittorrent client/server system. A daemon program handles all the file transfers as a Bittorrent client. The GSTorrent daemon also acts as a server for an external GUI client.
The objective is to have a relatively small Bittorrent client, which runs on a small computer without a graphical interface and to control this server from a different machine.
An example of this type of architecture is the mldonkey client/server system for the edonkey protocol.
Enhancements:
- The torrent hash problem is fixed.
- The upload/download rate settings finally work correctly.
- A better torrent selector.

Net::Nessus::Client is a Nessus client module.

SYNOPSIS

# Connect to the Nessus Server
require Net::Nessus::Client;
my $client = Net::Nessus::Client->new(host => localhost,
port => 1241,
user => joe,
password => my_password);

The Nessus program is a Client/Server application offering a framework for lots of security related scanners, so-called plugins. The idea is not to create a separate scanner for any possible security hole, but to reimplement only the most important parts and let the Nessus Server (nessusd) do the most part of the work.
Clients are typically available as GUI applications, for example based on the GTK (nessus), Java or Win32 applications. This module is another Nessus client written in Perl, but without GUI.

You start using the module by opening a connection to a Nessus Server: This will create a Nessus client object for you. This object offers methods that you can later use, for example retrieving the list of available plugins, start a scan, set preferences and so on.
