IP Manager was written to help ease the pain of ISP's and IT departments keeping their netblocks organized. The IP Manager automatically subnets and sorts all the IP blocks in the table. No need to memorize tough subnetting schemes and
performing tough subnet calculations. The IP Manager keeps this in one easy process. Also included with the program is a simple router configuration utility. It was designed for Cisco routers, but could be easily adapted to other vendors. If you enable telnet for an IP, you will see the utility. This software is free to use and distribute, if you make any meaningful changes, email email@example.com with the details. Version 2.0 update: IP Manager now performs basic networking monitoring tasks.
phpBandwidth is a PHP program able to monitor a particular network interface (eth0, eth1, ppp0, etc...). His goal is to provide a realtime graph showing bandwidth consumption on a server. phpBandwidth is free to use but restricted, this mean if you want update the source code and/or use this code within a commercial context, you're pleased to take a licence.
Node Runner is a PHP network monitor designed to contact nodes in a specific order based on the description of the node. If a node does not respond, each of its dependencies are systematically checked until the problem is isolated. Node Runner uses a shell script for its basic network polling, a PHP web interface for node information, reports, etc., and utilizes abstraction layers for database support.
This little script checks what a specified range or series of IP-numbers resolves into.
It then takes that resolved hostname, and checks with the corresponding DNS-server that the hostname points back at the originating IP. If they both match each other, the virtual host is considered to be online, and can therefore be used out on the Internet (on a BNC, a webserver and so on). A live demo can be seen at http://vhost.xil.us
The networking utilities includes a ping tool, a traceroute tool and an nslookup tool. These are very commonly available tools, however by making them web-based, it allows you and your clients to test connectivity from a centralized location, thus helping you track down common problems on your network, or a clients network.
