The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
Apache has been the most popular web server on the Internet since April of 1996. The May 2003 Netcraft Web Server Survey found that 62% of the web sites on the Internet are using Apache, thus making it more widely used than all other web servers combined.
The Apache HTTP Server is a project of the Apache Software Foundation.

Linbox Directory Server (LDS), along with the Linbox Management Console (LMC), is a powerful system that allows developers, system administrators, and other software vendors to manage users, groups, and their associated policies in an LDAP server.
Linbox Directory Server is highly ergonomic interface design makes it very easy to use, and delegation of administration enables medium size organization to adopt LDS.
Enhancements:
- New features and improvements include DNS/DHCP management and a Norwegian translation.
- The new DNS/DHCP module allows you to manage DNS zones and DHCP subnets for a typical LAN environment.

SILC Server provides system administrators ability to easily and quickly set up new SILC networks. SILC Server is full implementation of server side of the SILC protocol.
SILC Server is ideal for small offices and organizations to set up secure conferencing network in LAN. SILC Server is compact and fast, and scales easily to Internet usage as well.
SILC Server provides full featured implementation of server side of the SILC protocol. The SILC Server is intended for system administrators who would like to set up either own SILC router or SILC server.
SILC Server is ideal for small offices and organizations to set up secure conferencing network in the local area network (LAN). SILC Server project is also suitable for Internet usage as it scales well, is compact and fast.
SILC Server can act either as SILC router or SILC server. It is also able to act as Backup router and take the responsibilities of the primary router if it becomes unresponsive. If your network has only one server then SILC Server acts by default as router server. Small LAN networks manage fine with only one SILC Server so it is very easy and fast to set up.
The difference of router server and normal SILC server is that router server handles most of the message routing and also keeps the global network state up to date. Normal SILC server on the other hand handles only local users and message routing to them. This arrangement makes the SILC network fast and scalable. SILC Server is easy to configure to act either as normal server or router server.
Whats New in 1.0.4 Stable Release:
- This release fixes a small problem with parsing the 1.3 protocol version string correctly.
- Clients that conform to the 1.3 protocol will not be able to connect to a SILC server that isnt running this version.
Whats New in 1.1 Beta 1 Development Release:
- Support for the new SILC Toolkit was added.

SS5 is a socks server that implements the SOCKS v4 and v5 protocol. As a proxy server, SS5 authenticates, profiles and processes network requests for clients.
Socks Server 5 establishes connections to application hosts for client applications. When the client attempts to access the network, the client connects to the SS5 daemon instead of the application host.
Following authentication, clients request that SS5 perform network activities for the client.
The activities might include:
CONNECT
BIND
UDP ASSOCIATE
The SS5 protocol is independent of application protocols, and can assist with different networking services, including telnet, ftp, finger, whois, gopher, and WWW access.
Enhancements:
- Fix code
