Hawk is a web based utility for monitoring and comparing hosts on your network with what is in DNS. Hosts that are answering pings but are not in DNS may be unauthorized, and addresses in DNS which are not answering may be able to be reclaimed. Hawk monitors all hosts on the networks you specify and lets you view them via a web page. Hawk consists of a backend written in Perl that monitors hosts by ICMP pings and writes the status to a mysql database. The frontend is in PHP and lets you select which network to view, and how to view it. This version has several enhancements to the original; including cleaner Perl code, a user-definable string to designate unused addresses that are in DNS, testing that the forward and reverse hostnames match, and the daemon forks one process pre subnet.

IP Stack Integrity Checker Its purpose is to test the stability of an IP Stack and its component stacks (TCP, UDP, ICMP et. al.) It does this be generating random packets of the desired protocol. The packets can have tendencies. ie by default all packets have a 50% chance of having IP Options. The packets are then sent against the target machine to either penetrate its firewall rules or find bugs in the IP stack.

Jnettop is a traffic visualiser, which captures traffic going through the host it is running from and displays streams sorted by bandwidth they use.

LG is a Looking Glass written in Perl as a CGI script. It can execute almost all BGP-related commands and do ping and traceroute in routers or relay these queries to other looking glasses. It supports both IPv4 and IPv6 commands, and is tested with Cisco, Zebra and Juniper. It can connect to router using either SSH, telnet or rsh protocol.

mtrace is a program to trace the routes taken by IPv4 multicast traffic flows.

klg is a looking glass written in PHP that can access and report back routing information from Cisco, Juniper and Zebra/Quagga routers. It can also lookup AS numbers to names via WHOIS interfaces, and supports friendly BGP community names via MySQL database.

The OpenLLDP project aims to provide a comprehensive implementation of the IEEE standard 802.1AB Link Layer Discovery Protocol. LLDP is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as Extreme's EDP (Extreme Discovery Protocol) and CDP (Cisco Discovery Protocol).

SNMP::Info gives an object oriented interface to information obtained through SNMP. This module is geared towards network devices. Subclasses exist for a number of network devices and common MIBs. The information may be coming from any number of MIB files and is very vendor specific. SNMP::Info provides you a common method for all supported devices. Adding support for your own device is easy, and takes little much SNMP knowledge. The module is not limited to network devices. Any MIB or device can be given an objected oriented front-end by making a module that consists of a couple hashes. See EXTENDING SNMP::INFO.

A set of utilities to configure and monitor several popular wireless access points using SNMP. Among other things, they allow access restrictions, MAC authorization and WEP encryption for access points and "wireless gateways" by Linksys, Netgear, SMC, and D-Link. -- Dan Pelleg daniel+aputils@pelleg.org

rcpd is a RCP server intended specifically for router or network device clients. It is used to transfer configurations, boot images, and kernels images (eg: IOS) to the devices. These files are often tranfered with TFTP, but TFTP has reliability and speed issues and file size limitations due to it's protocol specification and underlying transport; while RCP is not affected.
