encapsulate provides its client process the same environment it's started in, except for some limitations: encapsulate remounts the whole filesystem read-only, except for user-selectable regions which are mounted read-write. It also isolates the process from the system's process table, network interface, IPC, and shared memory tables.

pexconfig allows you to use a PXE-enabled network card as the first boot device for a system. This software suite also includes PXE-menu tools, which are used to control the booting of networked computers directly from the computer's console at the BIOS level before any operating system has been loaded. The menus provided by these tools can be used for diagnostic purposes, for firmware upgrades, or for selecting an operating system installation method.
Simple Configuration Management provides lightweight configuration management when you don't want to implement a more robust tool like puppet or cfengine. It trades off functionality for simplicity and aims to only provide the bare essential functionality needed to configure a host or its software.
netstat-monitor is a commandline tool for monitoring network connections. Its output is similar to the output from the netstat command with the options "netstat --inet -alp". Netstat-monitor can be left running, though, and will report new connections as they are made. Also, filters can be created to limit what's displayed to just what's unexpected or interesting.
