glNetViz is a tool for visualizing computer network topologies with WebGL. With the abilities of real time visualizing network traffics flowing around the local network and to/from the Internet, you can manage the various network more easily and efficiently. glNetViz is intended to be a convenient tool that can easily visualize the network topology from the serialized data in YAML or JSON.
RubyDNS is a high-performance DNS server that can be easily integrated into other projects or used as a stand-alone daemon (via RExec). By default, it uses rule-based pattern matching. Results can be hard-coded, computed, fetched from a remote DNS server, or fetched from a local cache, depending on requirements. In addition, RubyDNS includes a high-performance asynchronous DNS resolver built on top of EventMachine. This module can be used by itself in client applications without using the full RubyDNS server stack.
izBalancing is a bash script featuring an in/out multi-homed load-balanced Internet gateway traffic manager with a failover facility. It features multiple balanced default gateway configurations, load-balanced outgoing connections from LAN to Internet connections, and management of multiple incoming connections from many Internet ISP lines to DMZ/LAN Servers. It is a SystemV compliant script, and can be easily run at boot. It will automatically discover your local IP addresses. You can cleanly start and stop your multi-homed configuration with a simple command (izbalancing start|stop|restart). Adding new Internet connections is very fast and easy: you need only provide the interface name, router IP address, and a descriptive name. If the izping daemon is installed into /etc/rc.d/init.d/, it will be used for automatic failover and recovery of Internet lines.
Counters.pl collects the CLI counters from network devices and produces custom reports. These counters can be reset independently of the SNMP counters, and when collected weekly, can highlight issues such as connection errors that you will not see looking at graphs produced from SNMP counters. They also contain information that is not available via SNMP. The reports can be viewed on a Web site and/or sent via email. There is a flexible configuration language in which reports can be specified. The format and style of the HTML reports are controlled by Template Toolkit templates and CSS. Currently only Cisco network equipment is supported.
NetConnect is a command line tool for automating the login process to routers, switches, or UNIX hosts and any intermediate devices or proxies in the path. It does this by using credentials supplied within a configuration file. It also allows users to run Perl based scripts on a single device or devices in parallel to automate tasks. Although it was originally designed around Cisco routers and switches, it can be extended to work with any CLI based device by specifying custom prompts that different devices use. It works well with Cisco routers and switches as the concepts around "enable" mode and the corresponding syntax of the prompt are contained within the source. Devices can be stored within your configuration file, so you are able to connect to devices using a portion of their name (using regular expressions) as opposed to having to remember IP addresses or full DNS names.
