Free session initiation protocol software for linux

Session Directory Tool provides a multicast session directory manager.
SDR is a session directory tool designed to allow the advertisement and joining of multicast conferences on the Mbone. It was originally modelled on sd written by Van Jacobson at LBNL, but implements a later version of the session description protocol than sd does.
SDR was originally written under the MICE and MERCI projects at UCL by Mark Handley who now works for ISI. SDR will continue to be maintained on a limited basis as part of the infrastructure for conferencing on the CAIRN testbed network and the EC MECCANO project.
Many many fixes and improvements to SDR have been contributed by Bill Fenner and Van Jacobson. Security features were implemented by Edmund Whelan and Goli Montasser-Kohsari at UCL.
Enhancements:
- new application media type for session directories
- fixed byte ordering of headers on intel machines
- fixed IP6 address allocation for unix IP6 stacks
- Authentication and encryption code fixed to allow for extra space for IPv6 addresses
- Added IPv6 flags to configure scripts "--enable-ipv6"

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.

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.

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.

VNC Session Manager provides a disconnected session manager for VNC.

VNC Session Manager adds the necessary glue code between VNCs two execution modes, enabling XDM-based login to disconnected sessions. This gives a Terminal Services-like login for Unix-based VNC servers.

TAHI Test Suite provides a mechanism for validating an IPv6 implementation against a standardized test for conformance to the IPv6 specification, extensions and directly related protocols.
Enhancements:
- Ported FreeBSD-4.x
- Dont support FreeBSD 2.x
- pa can decode MIP6 packets
- All interoperability test tools is included.

Session Manager allows you to save and restore the state of all windows.

Session Manager saves and restores the state of all windows - either when you want it or automatically at startup and after crashes. Additionally it offers you to reopen (accidentally) closed windows and tabs. If youre afraid of losing data while browsing - this extension allows you to relax...

This extension replaces SessionSaver and Tab Mix Plus session manager. It stores more data than both of them and should be more reliable in saving and restoring. Although it is not recommended to have more than one session related extension installed, Session Manager is compatible at least with Tab Mix Plus.

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 => ...

METHODS THAT CAN/MUST BE OVERWRITTEN

$self->setup ($setup)

Called after the last setup packet has been received, just before an addme request is sent.

$self->addme_success

$self->addme_failure

$self->eof

$conn->anim_update ($num) [OVERWRITE]

$conn->sound_play ($x, $y, $soundnum, $type)

$conn->query ($flags, $prompt)

$conn->drawextinfo ($color, $type, $subtype, $message)

$conn->drawinfo ($color, $text)

$conn->player_update ($player)

tag, weight, face, name

$conn->stats_update ($stats)

$conn->container_add ($id, $item...)

$conn->container_clear ($id)

$conn->item_update ($item)

$conn->item_delete ($item...)

$conn->spell_add ($spell)

$spell = {
tag => ...,
level => ...,
casting_time => ...,
mana => ...,
grace => ...,
damage => ...,
skill => ...,
path => ...,
face => ...,
name => ...,
message => ...,
};

$conn->spell_update ($spell)

(the default implementation calls delete then add)

$conn->spell_delete ($spell)

$conn->magicmap ($w, $h, $px, $py, $data)

$conn->map_change ($type, ...)

$conn->image_info ($numfaces, $chksum, [...image-sets])

$conn->map_change ($mode, ...) [OVERWRITE]

current < flags > < x > < y > < width > < height > < hashstring >

$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.
