Ulog enables you to list past and present X11 sessions on a whole domain of machines. It is the X11 equivalent of "who" or "last" commands, with much more sophisticated options and search criteria (such as login username, hostname, display name, login/logout times, etc.). It relies on a ulogd daemon which keeps track of events (login, logout, etc.) sent via, for example, the startup and reset scripts of xdm.
IP Traffic Volume uses Linux kernel iptables to log incoming and outgoing bytes though your network device(s) and can dump summarized log statistics in ASCII to the console or display in HTML via the included CGI interface for displaying on a Web server. It is highly configurable as to what kind of traffic is counted, e.g. to and from specific ports and/or specific IP addresses or groups of ports and addresses. It uses a mininum of resources and doesn't need a database for the logged data.
RadiusSplit is a Perl program designed to take, as input, one or more large RADIUS accounting "detail" log files, and split them out into individual files - one per user. The net result is that you will have a detail file per user, which can be passed to other RADIUS parsing logfile analysers (e.g. RadiusReport) so they run much faster (usually be a factor of several hundred), since they don't have to parse and discard the non-relevant data.
Network Shell Utilities: A command line UNIX shell that provides a centralized management platform for 12 operating systems (Linux, Solaris, etc.). We provide native support for over 130 standard UNIX commands, extended to leverage Network Shell's distributed technology. This allows administrators to execute commands on multiple machines simultaneously. Network Shell Deploy: A GUI tool that provides a simple way to obtain system inventory/audit, patch management, package/application management, and content distribution/management. In addition, deploy uses the Network Shell script engine - any job created in the GUI can be saved as a Network Shell script, and modified as required by the administrator.
