Balance is a simple but powerful generic TCP proxy with round-robin load balancing and failover mechanisms. Its behavior can be controlled at runtime using a simple command line syntax. Balance supports IPv6 on the listening side, which makes it a very useful tool for IPv6 migration of IPv4 only services and servers.
DansGuardian is a Web content filtering proxy that uses Squid to do all the fetching. It filters using multiple methods including, but not limited to, phrase matching, file extension matching, MIME type matching, PICS filtering, and URL/domain blocking. It has the ability to switch off filtering by certain criteria including username, domain name, source IP, etc. The configurable logging produces a log in an easy to read format. It has the option to only log text-based pages, thus significantly reducing redundant information (such as every image on a page).
PyDSH is a toolset to help simplify the administration of remote systems. The pydsh command enables running of a command on multiple hosts in parallel over RSH, SSH, or telnet, and manages your SSH public and private keys. The pydcp command enables SCP-like functions to and from multiple hosts in parallel.

Simple network top (sntop) is a curses-based console utility in the spirit of top that polls network hosts at a regular interval to determine their connectivity and displays the results in a pretty format. Advanced features are supported, such as automatic HTML generation of results, secure terminal mode, execution of an external file on connectivity changes, a daemon mode, and user/system configure files.
