DUMA (Detect Unintended Memory Access) stops your program on the exact instruction that overruns (or underruns) a malloc() memory buffer. GDB will then display the source-code line that causes the bug. It works by using the virtual-memory hardware to create a red-zone at the border of each buffer: touch that, and your program stops. It can catch formerly impossible-to-catch overrun bugs. DUMA is a fork of Bruce Perens' Electric Fence library.
Webfwlog is a Web-based firewall log reporting and analysis tool. It allows users to design reports to use on logged firewall data in whatever configuration they desire. Included are sample reports as a starting point. Reports can be sorted with a single click, or "drilled-down" all the way to the packet level, and saved for later use. Supported log formats are netfilter, ipfilter, ipfw, ipchains, and Windows XP. Netfilter support includes ulogd MySQL or PostgreSQL database logs using the iptables ULOG target.
cw is a non-intrusive real-time ANSI color wrapper for common Unix-based commands. It is designed to simulate the environment of the commands being executed, so that if a person types 'du', 'df', 'ping', etc. in their shell it will automatically color the output in real-time according to a definition file containing the color format desired. It has support for wildcard match coloring, tokenized coloring, headers/footers, case scenario coloring, command-line- dependent definition coloring, and includes over 50 pre- made definition files.
