SNARLsnmp is a monitoring tool for dynamic Web applications. It dynamically creates and assembles URLs and scans them at arbitrary intervals, performs predefined checks on URL content, size, and timing, notifies a monitoring application via informative SNMP traps if a predefined error condition (event) has been met, and delivers a snapshot of its current tests and results at any given time. It is built as a truly multi-threaded MIB module for net-snmp 5.0.3 and higher. Its current monitoring status can be retrieved via the net-snmp daemon's SNMP request interface. configuration of the URL tests is done via a configuration file in a human readable format. All configurations can be hot updated. No data will be lost when reconfiguring a running SNARLsnmp.
fsdb speeds the creation of slocate's database files by keeping its own database and updating only those parts that need to be updated. It connects to a daemon to receive the updated inodes. In turn, the daemon interfaces with a kernel module which hooks into Linux's dnotify mechanism.
vtwatch automatically switches the active virtual console on your Linux system in a loop, acting as a virtual terminal surveillance monitor. The speed at which they switch is configurable, and it is possible to input a search string, which you are notified about if it is found on a console.
IRMix is an audio mixer application for Linux. It uses the Lirc infra-red receiver system to provide an imitation of a TV's on-screen display, and handles making audio volumes controllable from an infra-red remote control. If your X server supports the Xft extension, Irmix will use it to add a nice translucency effect to the OSD window.
PFinger is a highly configurable, secure and portable finger deamon. It is started by inetd but does not run as root. The service may be disabled for individual users by the administrator or by the users themselves. It offers configurable special files (e.g. a users PGP-Key could be retrieved with 'finger john.pgpkey@host), no printing of users home directory or shell and it also provides a graphical frontend that allows users to easily alter the output that will be sent, when they are fingerd.
LKMB is a Perl module that can be used to create a kernel module package, that can later be used to create a package that can be bootstrapped on any GNU machine. It is incomplete, but still partially usable. LKMB is part of the Comprehensive Linux Archive Network (CLAN) meta-project.
Crossover is a fast Linux daemon intended to be used as a load-balancing tool for various Web services. It is designed to have many Web servers hidden behind one firewall/IP address. It is simple to use, maintain, or extend. A small patch to Apache is needed in order to see client IP addresses on the Web server. It has been used to route multi-gigabyte traffic without any problems.
