Free wire protocol software for linux

The HTTP Time Protocl (HTP) system is a set of utilities to set and maintain the system clock from the HTTP/1.1 (RFC 2616) "Date:" header. HTP requires Libconfig.
The purpose of HTP is provide a simple to use system that can be used on any system that is connected to the internet and can access atleast one web page (either directly or through a proxy) to be able to maintain an accurate clock.
HTTP Time Protocol uses basic statistical analysis to arrive at the most accurate time possible given enough servers. The more servers HTP is configured to use the more accurate the clock can be.
Enhancements:
- Cleanup/simplification of the code.
- A more robust implementation of the "-p" (precision) switch.

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

Crossfire::Protocol::Base is a client protocol module.

SYNOPSIS

use base Crossfire::Protocol::Base; # you have to subclass

Base class to implement a crossfire client.
new Crossfire::Protocol::Base host => ..., port => ...

$conn->map_clear [OVERWRITE]

Called whenever the map is to be erased completely.

$conn->map_update ([ [x,y], [x,y], ...]) [OVERWRITE]

Called with a list of x|y coordinate pairs (as arrayrefs) for cells that have been updated and need refreshing.

$conn->map_scroll ($dx, $dy) [OVERWRITE]

Called whenever the map has been scrolled.

$conn->face_update ($facenum, $facedata, $changed) [OVERWRITE]

Called with the face number of face structure whenever a face image becomes known (either because face_find returned it, in which case $changed is false, or because we got an update, in which case $changed is true).

$conn->face_find ($facenum, $facedata) [OVERWRITE]

Find and return the png image for the given face, or the empty list if no face could be found, in which case it will be requested from the server.

$conn->send ($data)

Send a single packet/line to the server.

$conn->send_command ($command[, $cb1[, $cb2]])

Uses either command or ncom to send a user-level command to the server. Encodes the command to UTF-8.

If the server supports a fixed version of the ncom command and this is detected by this module, the following is also supported:

If the callback $cb1 is given, calls it with the absolute time when this command has finished processing, as soon as this information is available.

If the callback $cb2 is given it will be called when the command has finished processing, to the best knowledge of this module.

ZRTP Protocol Library is an implementation of Phil Zimmermanns ZRTP protocol, created based on and interoperable with Zfone beta 2.

Using this package, together with GNU ccrtp (1.5.0 or later) provides a zrtp implimentation that can be directly embedded into client and server applications, rather than the overhead penalty of using an external proxy such as zphone. The first application to demonstrate this capability is the 0.8.2 release of the Twinkle softphone client.

Please note, this library is licensed under the GNU GPL, version 2 or later, and has been copyright assigned to the Free Software Foundation.

Wired project aims to be a professional music production and creation software running on the Linux operating system. Wired supports unlimited Audio/Midi tracks playback and recording, and introduces a Plugin system for instruments and effects. It can also read AKAI CDs and import 18 different Wave formats.

The following instruments and effects are being developed:

Loop sampler, with pitch shifting and time-stretching
Beatbox with a new editing concept, to create reallistic and complex drum sequences
MIDI controlled sampler, which can read AKAI program and sample files.
High-pass, Low-pass and Notch filters
Compressor/Limiter
Delay

Wired is composed of a Audio/MIDI sequencer and a rack based plugin system, which enables you to record your instruments and mix them with electronic effects at the same time. The user interface of Wired has been designed to make it easy for professionals or beginners to compose music in a software based environment.

Wired targets the Linux operating system, and uses GTK and wxWindows for the graphic interface. It supports the ALSA sound architecture and OSS for Audio and MIDI I/O.

The following parts of the project are already implemented :

Multitrack Audio playback and recording
Multitrack Midi playback and recording
Sequencer engine
ALSA/OSS/Jack Audio support
ALSA MIDI Input support

libptp2 is a library used to communicate with PTP devices like still imaging cameras or MP3 players (KODAK mc3).
You can download files or tweak camera properties using ptpcam program boundled with libptp2.
Supported Cameras
The list of cameras implementing PTP is constantly growing. Most (if not all) USB still cameras designed after 2002 are supporting PTP. Below is the list of vendors implementing PTP in their cameras:
- Kodak
- HP
- Nikon
- Canon
- Panasonic
- Olympus
- Konica
- Minolta
- Fuji
- Ricoh
- Sony
More are comming...
Please note that if your camera is supporting PTP it does not mean that it is capable of performing all PTP operations (like trigerring capture, uploading files or tweaking properties). Sony cameras are good example of poor PTP implementation where the only thing you can do is downloading files. Sony even breaks the USB specification assigning all its cameras the same product/vendor IDs so dont buy Sony if you want to stay out of problems.
Currently most PTP features are supported. Uploading/downloading files, taking pictures and setting camera properties is supported as long as your camera supports it. However there are many Vendor Extensions that are not supported.
For example Canon uses some proprietary extension operations to take pictures (entering capture mode, extending lens and so on), Nikon introduces proprietary PTP properties.
Unfortunately I have access to couple of Kodak cameras only so to help support extension features you may send me a patch or donate/lend the camera.
Enhancements:
- A number of bugs were fixed, including leaving the camera in an unpredictable state when an I/O error occurs.
- The projects own reimplementation of the old libusb interface (IOCTL_USB_BULK) is used instead of the new URB interface, which is 20% to 50% slower and sometime leads to I/O errors.
- File time preservation across download was added.
- Better capture support was added.
- A bug that caused files over 2MB to be corrupted while downloading was fixed.
- The --loop-capture feature was added.
- Configure errors and parralel build with make -j were fixed.

Gip is an IP address calculator that integrates well with the GNOME desktop environment.

Gip provides system administrators with tools for IP address based calculations. For example, an administrator who needs to find out which IP prefix length equals the IP netmask 255.255.240.0, just types in the mask and gets the prefix length presented. But many more advanced calculations can be made.

Gip can convert an address range into a list of prefix lengths. It can also split subnets using a given IP netmask or IP prefix length. Many more calculations are possible.

Multi-Protocol Remote Login provides a middleware allowing SSH, telnet, and local logins from the login: prompt.
MPRL is a middleware application between a *getty program and SSH, telnet, and other such remote-login protocols. It allows a user at a Linux terminal to log into other systems without needing a valid local user-id. It currently supports telnet, ssh, and /bin/login.
It syntax follows the [protocol:]user[@host][:port] fashion.
These are valid logins:
- buanzo - Normal local login: /bin/login gets called.
- buanzo@linux.org.ar - SSH protocol by default: /usr/bin/ssh gets called
- ssh:buanzo@webserver.algo.net
