Eclipse Instant Messenger Plugin is a plugin for Eclipse. It integrates some popular im protocols(MSN,YAHOO,ICQ,AIM,etc.). Eclipse is a kind of universal tool platform - an open extensible IDE for anything and nothing in particular. You can have more infomation from www.eclipse.org.

SimpServer is the first lightweight instant messaging security gateway for Unix systems. Install SimpServer on a Unix system and configure IM clients on your local network, and conversations with Simp-equipped parties will be automatically encrypted. SimpServer can indeed accept simultaneous remote connections and thus secure local and/or remote clients.
With SimpServer, corporate environments can now benefit from centralized instant messenger encryption. Linux fans can now secure their MSN conversations. SimpServer is beta and is free for any use.
Main features:
- This version of SimpServer supports MSN Messenger, ICQ, Yahoo! and AIM encryption using the Diffie-Hellman key-agreement scheme. It does not currently support authenticated modes such as the RSA modes of the Windows version, nor does it support other IM protocols. That limitation brings an important advantage: SimpServer can be used as a security server for multiple IM clients, not only the one on the local machine, but others on the network. It is indeed possible to configure clients to use SimpServer as a proxy server, which will secure all outgoing IM flows.
-
-As for the Windows version, the Unix edition can be highly customized: messages can be colored depending on their cryptographic state and contact names can be prefixed during conversations (MSN) to quickly see if the conversation is secure.

Kxremote is an application to integrate protocols of remote connection made with perlqt.
Supports:
- xdmcp
- vnc
- rdp

IM-Filter is a daemon for GNU/Linux firewall hosts written in C which is able to analyze and filter the ICQ protocol. The daemon runs in userspace and fetches packets of the ICQ protocol by using the libnetfilter_queue mechanism.
IM-Filters main purpose is to run at a gateway, so all ICQ-related traffic of users in the LAN runs over IM-Filter. Nevertheless the daemon could also be used directly on end users computers. The following diagram shows, how the daemon is integrated in a GNU/Linux system.
One of the design goals of IM-Filter was modularity. So plugins for other protocols like MSN or IRC could be written easily. The source code already contains skeleton code for an IRC module.
Together with the source code, adequate iptables scripts are provided so that only packets which belong to ICQ traffic get in the netfilter queue of IM-Filter.
Main features:
Logging of messages sent via ICQ
IM-Filter is able to identify and log messages which have been sent via the ICQ protocol. These messages contain a timestamp, an IP-address, the appropriate UIN and - of course - the message itself. A logged message could look like this:
[2007-07-27 11:24:21] IP "10.0.0.1" sent following message to #123456789: "hello, this is a test"
Blacklists for messages and UINs
IM-Filter handles two different blacklists: for messages and for UINs. The message blacklist holds strings which must not occur in text messages. When such a string is detected in a message, it gets censored in the logfiles.
The UIN blacklist contains UINs of users which are not allowed to connect to the ICQ network. Those blacklists can be re-read by the daemon during runtime by sending signals.
Detection and blocking of file transfers
Since file transfers are not always welcome, they can be blocked by invoking the daemon with a specific command line argument. Then, users in the LAN can not send files to other users anymore. Beside blocking, the daemon logs file transfers. Such a log entry can look like this:
[2007-07-06 17:01:26] FILTRANSFER detected (outgoing): receiver uin: #123456789 || filename: test.txt || size: 143360B
List with currently logged in users
To be able to know which users are currently logged in, IM-Filter manages a text file which holds all necessary information. By default, the file is placed in /var/log/imfilter.users and contains IP-address and UIN of the users which are currently logged in. The file could look like this:
UIN=123456789, IP=10.0.0.1
UIN=234567890, IP=10.0.0.22
UIN=345678901, IP=10.0.0.4

Net::YMSG is a Perl interface to the Yahoo! Messenger IM protocol.

SYNOPSIS

use Net::YMSG;

my $yahoo = Net::YMSG->new(
id => your_yahoo_id,
password => your_password,
);
$yahoo->login or die "Cant login Yahoo!Messenger";
$yahoo->send(recipient_yahoo_id, Hello World!);

Net::YMSG is a client class for connecting with the Yahoo! Messenger server, and transmitting and receiving a message.

Since implement of a protocol is the result of analyzing and investigating a packet, it has an inadequate place. However, it is working as expected usually.

METHODS

This section documents method of the Net::YMSG class.

Net::YMSG->new()

It should be called with following arguments (items with default value are optional):

id => yahoo id
password => password
pre_login_url => url which refers to setting information.
(default http://msg.edit.yahoo.com/config/)
hostname => server hostname
(default scs.yahoo.com)

Returns a blessed instantiation of Net::YMSG.

Note: If you plan to connect with Yahoo!India (yahoo.co.in), it sets up as follows.

my $yahoo_japan = Net::YMSG->new(
pre_login_url => http://edit.my.yahoo.co.in/config/,
hostname => cs.yahoo.co.in,
);

Since it connects with Yahoo!(yahoo.com), this procedure is unnecessary in almost all countries.

Emcast project is a generic multicast toolkit.
Emcast is a multicast toolkit for distributed/peer-to- peer applications that require multicast communication.
It includes the program "emcast", a generic multicast utility (like netcat), and the library "libemcast", a generic multicast library.
Emcast supports IPv4 multicast (IM) and can easily support almost any end-host multicast (EM) protocol.
The EM protocols supported are Banana Tree Protocol (BTP) and Internet Relay Chat (IRC).
Enhancements:
- Copy from inet address, not string. Interesting that mcast was still working before in Linux.
