sonar is a network reconnaissance utility. It runs all its scans from plugins. The currently supported plugins are an ICMP scan (a la the original sonar) and an ACK scan which can see if hosts that don't respond to ICMP are online. With the ability to create your own plugins, sonar is becoming the most extensible security scanner available.

Release Notes: Major updates were made, including new plugins, better documentation, logging to syslog, and working input/output plugins. You can now compile plugins from outside the sonar source-tree, making it easier to start your own plugin projects after sonar is already installed. Results are now reported in a general format that output plugins can recognize and parse however they want. Fixes for a gcc 2.95 compile bug were included.
Release Notes: A massive codebase update was made. A better framework was added. Plugins now have a separate error handler. config_aux_dir was changed to admin. Unneeded files were removed. The project was libtool-ized. All plugins are now libtool libraries. The plugin directory is no longer hardcoded. Many other changes were made.
Release Notes: This release has major upgrades: tweak indentation fixes, a new man page, a complete overhaul of the Makefiles, and revamping of the option parsing system. Upgrading is recommended.
