DynaFabric is an SSH-based command dispatching and systems management framework, designed for easy implementation on existing networks. It allows you to configure SSH key based authentication and centrally dispatch commands, manage installed software, maintain services, and enforce policies across your systems. It is designed to be platform agnostic; support is being developed for FreeBSD, OpenBSD, NetBSD RHEL/CentOS, Ubuntu, Solaris 10, Solaris 11, and Illumos.
dhcpy6d delivers IPv6 addresses for DHCPv6 clients, which can be identified by DUID, hostname, or MAC address, as in the good old IPv4 days. Addresses may be generated randomly, by range, or by arbitrary ID or MAC address. Clients can get more than one address, leases and client configuration can be stored in databases, and DNS can be updated dynamically.
MaheshaNetBSD is a NetBSD Live USB distribution which has the IceWM Desktop and the same feel as all the author's MaheshaBSD-based products. A LiveCD can easily be made from it by running the /makeiso script in the root directory. It can be used for many things like viewing presentations (PDF files, images, etc.), handling recovery tasks, playing music, playing chess, surfing the Internet, etc. Linux emulation is activated. The advantage of this LiveUSB is that the USB pendrive is writable after booting (unlike other MaheshaBSD products), and users can thus easily install packages from the Internet. However, as USB flash drives do not like too many writes, the author keeps a few directories in memory (/tmp, /var, /etc.). MaheshaNetBSD lets you can write in Sanskrit.
tcpdump prints a description of the contents of packets on a network interface which match a given boolean expression. It can also be run with the -w flag, which causes it to save the packet data to a file for later analysis, and/or with the -r flag, which causes it to read from a saved packet file rather than to read packets from a network interface. In all cases, only packets which match the expression will be processed by tcpdump. tcpdump logs more than just TCP, IP, or ethernet packets, but has a whole suite of decoders, including ones for USB.
Class::EHierarchy is intended for use as a base class where hierarchally ordered objects are desired. This class allows you to define a parent - child relationship between objects and ensures an orderly destruction of objects according to that relationship, instead of perl's reverse order destruction sequence based on reference counting.
