tcpdump prints a description of the contents of packets on a network interface which match a given boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets which match the expression will be processed by tcpdump. tcpdump logs more than just TCP, IP, or ethernet packets, but has a whole suite of decoders, including ones for USB.
dnscrypt-proxy acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS. The DNSCrypt protocol focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.
Python System Monitor (Psymon) is a cross-platform task and performance monitor. It features global process monitoring, system load history (CPU, memory, network, and disks), disk information, network connections, detailed information and CPU, and memory percentage history per process.
Freedom ERP is a business management system that can be used for retailers, wholesalers, manufacturers, service providers, call centers, and other organizations to provide inventory management, purchasing, sales, finance, and more.

mod_pLua is an Apache HTTP Server 2.x module for developing Web applications with Lua. With mod_pLua, you can use Lua for scripting in two distinct ways; Embedded Lua scripting, <?lua print("Hello, world!") ?>, or plain Lua scripting with a CGI-style interface. mod_pLua precompiles all scripts and caches the compiled binary code so that each new call to the same file will be lightning fast, allowing you to serve hundreds of thousands of requests per minute on any modern server. Mod_pLua supports both the traditional Lua interpreter as well as LuaJIT for both Windows and UNIX platforms. If your Web server supports it, mod_pLua also utilizes APR_DBD and mod_dbd to handle persistent database connections through the dbopen() Lua function.
Rumble is a mail server suite for SMTP (ESMTPSA), HTTP, POP3, and IMAP4v1 with an extensive C/C++ and Lua API for scripting. It comes with support for SSL/TLS, SQLite, and MySQL and has a Web-based administration and Web mail feature. Additional included modules feature greylisting, DNS blacklisting, SpamAssassin support, and dynamic performance scaling as well as a multithreaded structure that allows for clustering of multiple servers for one or all domains. With the Lua API you can create your own new server mailing lists, CRM software, e-marketing, and other extensions within minutes.
cmogstored is an alternative, C implementation of the "mogstored" storage daemon used for MogileFS storage nodes. This implementation allows MogileFS storage nodes to be deployed with a minimal memory/filesystem footprint with no additional runtime dependencies. This implements all HTTP/1.1 DAV functionality needed by MogileFS clients as well as the mogstored stream protocol. This project is still in the early stages of development and not directly affiliated with the MogileFS project.
2x2 (Two by Two) is a multiplication puzzle game. Your goal is to solve a multiplication puzzle in which all digits are replaced by letters. To achieve the best score, you should solve the puzzle with a minimal number of errors and in minimal time. 2x2 is easy to learn, but hard to master. It is simple, smart, and addicting. It will allow you to test and improve your math skills, calculation skills, logic, and even knowledge of probability theory. With a large number of possible combinations, no two games will be the same.
