pixilate parses an input file containing Cisco PIX 6.2x (normal mask) or Cisco IOS (inverted mask) access-list entries and generates the appropriate packets. For further information on writing PIX access-lists, look here, for information on writing IOS access-lists, look here. pixilate - is currently capable of generating TCP/UDP/ICMP (various ICMP types), and IGMP utilizing the Libnet 1.1.x library available from http://www.packetfactory.net. NOTE: Libnet 1.0.x is NOT compatible."

Portmon is a network service monitoring daemon. Portmon basically uses a list of hosts and port numbers, and tries to connect to each host on the list at a regular time interval. It is a lightweight program, and requires no software to be installed on the machines one wishes to monitor.

IPplan is a free (GPL), web based, multilingual, IP address management and tracking tool written in php4, simplifying the administration of your IP address space. IPplan goes beyond IP address management including DNS administration, configuration file management, circuit management and storing of hardware information. IPplan can handle a single network or cater for multiple networks and customers with overlapping address space.

IPy is a Python module for handling IPv4 and IPv6 Addresses and Networks in a fashion similar to perl's Net::IP and friends. The IP class allows a comfortable parsing and handling for most notations in use for IPv4 and IPv6 Addresses and Networks.

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.

A program for faking the standard Unix UDP-based traceroute.

ezRADIUS is FreeRADIUS and Chillispot web-based management software package.

flowd is a small, fast and secure NetFlow collector. It offers the following features: * Understands NetFlow protocol v.1, v.5, v.7 and v.9 (including IPv6 flows) * Supports both IPv4 and IPv6 transport of flows * Secure: flowd is privilege separated to limit the impact of any compromise * Supports filtering and tagging of flows, using a packet filter-like syntax * Stores recorded flow data in a compact binary format which supports run-time choice over which flow fields are stored * Ships with both Perl and Python interfaces for reading and parsing the on-disk record format * Is licensed under a liberal BSD-like license

Sipcalc is an ip subnet calculator. Features: IPv4 - * Retrieving of address information from interfaces. * Classful and CIDR output. * Multiple address and netmask formats (dotted quad, hex, number of bits). * Output of broadcast address, network class, Cisco wildcard, hosts/range, network range. * Output of a userdefined number of extra networks. * The ability to "split" a network based on a smaller netmask, now also with recursive runs on the generated subnets. * DNS resolution. IPv6 - * Compressed and expanded input addresses. * Compressed and expanded output. * Standard IPv6 network output. * Reverse dns address generation. * The ability to "split" a network based on a smaller netmask, now also with recursive runs on the generated subnets. * DNS resolution.
