hp2xx

HPGL converter into some vector- and raster formats

HP2XX reads HPGL ASCII source files, interprets them, and converts them into either another vector-oriented format or one of several rasterfile formats. Currently, its HPGL parser recognizes a subset of the HP 7550A command set. Some high-level functions are missing. Also, only some of the fixed space vector fonts and none of the variable space arc fonts are supported. Beside these limitations, hp2xx has proven to work with many HP-GL sources without any trouble.

hping3

Active Network Smashing Tool

hping3 is a network tool able to send custom ICMP/UDP/TCP packets and to display target replies like ping does with ICMP replies. It handles fragmentation and arbitrary packet body and size, and can be used to transfer files under supported protocols. Using hping3, you can test firewall rules, perform (spoofed) port scanning, test network performance using different protocols, do path MTU discovery, perform traceroute-like actions under different protocols, fingerprint remote operating systems, audit TCP/IP stacks, etc. hping3 is scriptable using the Tcl language.

ekeyd-egd-linux

Transfers entropy from an EGD to the Linux kernel pool

This utility reads from an EGD capable service over TCP and writes the entropy retrieved to the Linux kernel random pool. Typically this will be used on clusters or virtual hosts where direct access to useful entropy is hard.

ifmetric

Set routing metrics for a network interface

ifmetric is a Linux tool for setting the metrics of all IPv4 routes attached to a given network interface at once. This may be used to change the priority of routing IPv4 traffic over the interface. Lower metrics correlate with higher priorities.

xmorph

digital image warp and morph (x11)

Xmorph loads, saves, warps, and dissolves images, and loads, saves, creates, and manipulates control meshes which determine the warping. The technique was invented and first used by Industrial Light and Magic, and is commonly called "morphing".

html2wml

converts HTML pages to WML (WAP) or i-mode pages

html2wml converts HTML pages to WML or i-mode(tm) pages, suitable for being viewed on a WAP or i-mode devices, e.g. cell phones. The conversion can be done either on the command line to create static pages or on-the-fly by calling this program as a CGI.
