WebWasher consists of the three modules that filter content, protect privacy, and control access. WebWasher's standard filters prevent unwanted data objects on Web pages from being loaded, prevent information on users from being forwarded to third parties without the users' knowledge, and allow the user a controlled access to the Internet (wanted information gets through; unwanted Web pages or data are blocked).
Arb-Scan is a remote banner scanner written in bash and Perl. It supports 12 different services banner checks (daytime, ftpd, sshd, smtpd, domain, finger, httpd, pop2, pop3, nntp, imapd and snpp). It features IP file reading, logging, random IP scanning, ftp anonymous login checking and VRFY/EXPN smtp checking.
Lingerd is a daemon designed to take over the job of properly closing network connections from an HTTP server like Apache. This frees Apache from doing the very boring but time-consuming job of "lingering closes", and lets each Apache process go on to the next connection immediately. The end result is that Apache needs fewer processes to handle high loads, which saves memory, reduces kernel contention, and generally makes Apache more scalable.
The Kawa Scheme System is a full Scheme implementation, completely written in Java. Scheme functions and files are automatically compiled into Java byte-codes. Kawa does some optimizations, and the compiled code runs at a reasonable speed. It provides the usual read-eval-print loop, as well as batch modes. The Kawa compilation framework is also useful for implementing other languages on top of JVM. There is active development of XQuery (the XML query language), and less active development of Emacs Lisp, Common Lisp, and EcmaScript.
mod_sequester is a module for the Apache Web server 1.3 which allows you to control access to Web documents according to the date and time of the request. It provides four basic ways to control access: allow until time t, allow after time t, allow between times t and t', and allow except between times t and t'. It is useful for controlling access to time-sensitive things like press releases (disallow until after), special offers (allow until), or windowed 'this week only' opportunities (allow between).
