@1 Helpdesk XP Perl is a very powerful Web-based helpdesk system. It supports file attachments, hidden remarks, priority marking, etc. Unlike other similar products, this script does not use the conventional "assign/completed" method to close past tickets. Instead, it uses an intelligent method to sort/rank inquiry tickets. You can even tell whether your replies have been read by the visitors.
The Advanced Bash Scripting Guide is both a reference and a tutorial on shell scripting. This comprehensive book, the equivalent of 1,000+ print pages, covers almost every aspect of shell scripting. It contains 382 profusely commented illustrative examples, a number of tables, and a cross-linked index/glossary. Not just a shell scripting tutorial, this book also provides an introduction to basic programming techniques, such as sorting and recursion. Included scripts are the Game of Life, a Perquackey variant, a Morse code trainer, and an implementation of the Gronsfeld Cipher. This book is suited for both individual study and classroom use. It covers Bash, up to and including version 4.2. Note that users of miniaturized single-board computers running Linux, such as the Raspberry Pi and the Beagle Bone, would find this Guide useful for learning and running Bash scripts to explore and expand the capabilities of these small, but powerful machines.
Autossh is a program to monitor and automatically reestablish SSH connections. It is similar to rstunnel (Reliable SSH Tunnel), however, it is implemented in C, and is easier to set up and use, especially for connections to multiple hosts. Autossh has been compiled and tested on OpenBSD, Linux, and Solaris, and should run without needing changes on FreeBSD and NetBSD.
DynaFabric is an SSH-based command dispatching and systems management framework, designed for easy implementation on existing networks. It allows you to configure SSH key based authentication and centrally dispatch commands, manage installed software, maintain services, and enforce policies across your systems. It is designed to be platform agnostic; support is being developed for FreeBSD, OpenBSD, NetBSD RHEL/CentOS, Ubuntu, Solaris 10, Solaris 11, and Illumos.
Email Security through Procmail (the Procmail Sanitizer) provides methods to sanitize email, removing obvious exploit attempts and disabling the channels through which exploits are delivered. Facilities for detecting and blocking Trojan Horse exploits and worms are also provided.
HATop is an interactive ncurses client and real-time monitoring and statistics displaying tool for the HAProxy TCP/HTTP load balancer. HATop's appearance is similar to top(1). It supports various modes for detailed statistics of all configured proxies and services in near real-time. In addition, it features an interactive CLI for the HAProxy Unix socket. This allows administrators to control the given HAProxy instance (change server weight, put servers into maintenance mode, etc.) directly out of HATop (using keybinds or the CLI) and monitor the results immediately.
