bandwidthd tracks usage of TCP/IP network subnets and builds HTML files with graphs to display network utilization. Charts are built by individual IP to show their utilization over 2, 8, 45, and 400 day periods. It color codes HTTP, HTTPS, TCP,UDP, ICMP, VPN, and P2P traffic. Unlike MRTG, it tracks each individual IP address and subnets, not the status of any particular link. Static mode is fast and easy to set up and has few dependencies. Database mode supports filtering by subnet, multiple sensors, custom reports and intervals, and can process thousands of IPs efficiently. Network utilization can be logged in CDF or a backend database.
The Prelude Library (libprelude) is the glue that binds all aspects of Prelude together. Prelude is a hybrid Intrusion Detection framework implementing an open communication layer for use by any security application. libprelude is a library that enables Prelude components to communicate with the Prelude concentrator. It also makes it easy for third party software to be made 'Prelude Aware' (able to communicate with Prelude components). It provides common, useful features used by every sensor.
Webfwlog is a Web-based firewall log reporting and analysis tool. It allows users to design reports to use on logged firewall data in whatever configuration they desire. Included are sample reports as a starting point. Reports can be sorted with a single click, or "drilled-down" all the way to the packet level, and saved for later use. Supported log formats are netfilter, ipfilter, ipfw, ipchains, Cisco routers, Snort, and Windows XP. Netfilter support includes ulogd MySQL or PostgreSQL database logs using the iptables ULOG or NFLOG target.
Telconi Terminal is an unique network management application with interactive full-screen configuration editing, browsing, help facility support, debugging, and more. It focuses on common Cisco IOS functionality present with any hardware or software configuration, and complements the command line interface with a rich set of features. It is intended for users with knowledge of Cisco IOS, and is designed to work with any IOS-based device, such as routers and switches.
fs-check checks filesystem sizes to see if they are getting too full. It uses a configuration file that specifies the filesystems to check, email contacts, trigger thresholds (percentage or amount used/unused), and a report program to run. It includes fs-report, which shows things like the largest files, the newest files, the intersection of these and core files. It can be run from cron or as a daemon.
nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
x11vnc allows one to remotely view and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. It is designed to be compatible with all Unix variants and Mac OS X, and depends on a small set of standard libraries. It supports SSL/TLS and VeNCrypt encryption, Unix password logins, single port access, Zeroconf, file transfer, and UltraVNC extensions. It is part of the LibVNCServer project.
SimMon is a cross platform monitoring tool which runs on almost any OS that supports the Java Virtual Machine 1.4+. Monitoring is done through the execution of existing monitoring scripts (Perl/VBS) or existing shell commands. Currently monitoring scripts are available for Solaris, Linux, Mac OS X, and Windows based systems. Network devices can be monitored via the integrated SNMPv1 scheduler.
