sslsweep tests TCP services for the presence of SSL and reports things about the services found, such as the certificate's CN, the certificate's expiration timestamp, what kinds of ciphers the SSL service supports, and what versions of SSL the service supports. It can be used for security testing as well as ongoing monitoring of services. It can produce output in human readable text, HTML, and CSV. It can also run as a Nagios plugin. It can accept input on the command line or on standard input (one host:port pair per line). It can also accept Nmap scan output (in the greppable format) as input, and it will test all open TCP ports found by the Nmap scan.
Fing is a command line tool for network and service discovery. It provides you a complete view of any network in a very short time. Its smart discovery automatically detects the network type and uses the best technique to scan it. The best results are achieved on Ethernet networks (including Wireless ones), where Fing is able to detect all network hosts, firewalled ones included. The service discovery feature quickly detects active TCP services on a target host or network. Fing is based on Look@LAN.
Inject is program which can generate, inject and withdraw BGP routes, with a primary focus on network testing. It supports route and peer flapping, generation of random routes with (pseudo) random BGP attributes via a Cisco like CLI. Other features include a configuration file based on XML, test cases, help functions, and displaying of peer and route information.

Ditchers is a multiplayer action game where underground tanks use a variety of weapons to find and destroy each other. Tanks dig tunnels in the soil with a limited supply of energy that can be refilled only in homes (as well as health). the GUI is controlled mainly by mouse, while gameplay is controlled only by keyboard.
