Anjuta is a versatile Integrated Development Environment (IDE) for the GNOME desktop. It features a number of advanced programming facilities that include project management, application wizards, an on-board interactive debugger, an integrated glade UI designer, integrated devhelp API help, an integrated valgrind memory profiler, an integrated gprof performance profiler, a class generator, a powerful source editor, source browsing, and more.
Angst is an active sniffer, based on libpcap and libnet. It dumps into a file the payload of all the TCP packets received on the specified ports. It implements two methods for active sniffing. Angst is able to monitor ARP requests, and after enabling IP forwarding on the local host, it sends ARP replies mapping all IPs to the local MAC address. Also, it can flood the local network with random MAC addresses (like macof), causing switches to send packets to all ports.
ANGIF is a C library to generate GIF format output. It can generate animated GIFs or true-color (24-bit) GIFs (using both at the same time, however, does not display properly on common browsers). ANGIF is completely LZW-free. There is no code implementing the patented LZW algorithm. That also means there is no compression and the files will actually be larger than a raw file with the same image by about 13% to 16% more. Command line level test programs are included. This is a quick rough-cut beta version with documentation only in the source code (the source code actually is commented).
Angel is a simple yet useful tool to monitor the services on your network. Technically speaking, it's a Perl program that runs every 'n' minutes (usually fired from your cron) and calls different perl subprograms (referred to as "plugins" from now on) to do the actual testing. It will then generate an HTML table containing the status of your network.
