The Open Virtual Machine Tools (open-vm-tools) are an open source implementation of VMware Tools. They are a set of guest operating system virtualization components that enhance the performance and user experience of virtual machines. The tools are currently composed of kernel modules for Linux and user-space programs for all VMware supported Unix-like guest operating systems. They provide several useful functions like file transfer between a host and guest, improved memory management and network performance under virtualization, and general mechanisms and protocols for communication between host and guests and from guest to guest.

It provides an easy-to-use Web interface for DNS record management while implementing most of the advanced features provided by BIND.
The XE Toolkit is a multi-platform, network-aware, secure performance monitoring solution for tactical analysis of enterprise computing systems. It uses Java and provides an API in the form of Java jar files that contain the programmatic interfaces needed to craft custom tools. It remains a toolkit, perhaps more complex than the SE Toolkit, but also far more versatile.
SSID-based SMTP server changer for Evolution is a simple script that uses gconf and NetworkManager (via D-Bus) to check which wireless network (SSID) you are currently connected to, and updates Evolution's accounts list (in gconf) to point to the correct SMTP server for that network. It is useful for when roaming between wireless networks that are connected to different ISPs.
Based on ircu, Nefarious has features from various IRCds (Asuka, Bahamut, UnrealIRCd, and UltimateIRCd) with the intent of adding needed features to ircu without becoming too bloated or subject to anti-user behaviors. Most features can be activated or deactivated in the config file. Nefarious includes optional support for RBL-based blocking or marking, fakehosts, accounts, login-on-connect, half-ops, ban exceptions, mIRC color filtering chan-mode, network-wide bans (g-lines), and much more.
