TCPWebLog is a system that collects and aggregates Apache and Varnish Web server logs from multiple Linux computers. It uses a simple "client" program that pipes logs to a central server over a TCP connection, and a "server" program that receive the logs and quickly aggregates or splits them.
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.
mod_ipblock aims to provide protection from aggressive clients by blocking or reporting them with a script. Users can set a limit to simultaneous connections. When this limit is reached, the module will execute the defined command. You can then write a simple bash script which can run commands with sudo(8) in order to limit the client or notify the admins.
mod_rangelimit aims to provide protection from DoS attacks using the Range header in Apache. It does so by analyzing the ranges supplied in the Range header. It checks the headers before mod_setenvif, and if there is even one invalid range in the request, the whole request is declined. The module also checks the number of supplied ranges and the number of overlapping ranges. It provides two options, MaxRanges (defaulting to 20) and MaxOverlappingRanges (defaulting to 5).
GoAccess is a real-time Web log analyzer and interactive viewer for almost every Web server. It runs in a terminal and provides fast and valuable HTTP statistics for system administrators that require log monitoring and visual reports on the fly. GoAccess can monitor unique visitors, browsers, spiders, OS, hosts and IP geolocation, keyphrases, referring sites, status codes, etc. It has support for IPv6 and it parses nearly any Web log format.
RD Connection Manager is a comprehensive remote connection management and publishing solution. It supports the world’s most popular remote desktop management protocols and provides comprehensive functionality to help users and system administrators organize their remote connections in various environments within any organization. Administration is simple with the ability to manage accounts, groups, and permissions. Sensitive data, such as user account settings, are encrypted with SSL. Strong connection security is supported. A single sign on system allows a user to establish multiple remote connections instantly after logging in. Supported protocols include RDP v.5, RDP v.6, VNC, and Citrix ICA.
mod_sass is an Apache HTTPD module that automatically compiles SASS files into CSS. When a client's browser requests a SASS file, this module will fill the request with the compiled CSS. When a file is compiled, the resultant CSS is also cached. This means that the SASS is only compiled when the file has been modified, so the average wait time for the file is always very fast.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.
