DESCRIPTION ^
The Jabber::Connection package provides basic functions for connecting clients and components to a Jabber server.

Connection Manager allows you to pre-configure all this, and use a single consistant interface to get connected to all of these various systems.
Do you have to log in to a lot of different systems? If you do, odds are that you have to use a variety of methods. You probably have some systems that require ssh and others that only support rdesktop. For some you may have to use vnc. Some may only support telnet. Connection Manager allows you to pre-configure all this, and use a single consistant interface to get connected to all of these various systems.
To install from the source distibution type (you probably will have to be root):
make install
To make rpms for rpm-based ditros type:
make rpm
Main features:
- Command Line Interface - Connection Manager will have a command line interface that allows for easy initiation of any connection. Some users, especially system administrators, will prefer this method of interaction
- Qt/KDE interface - Connection Manager will have a full featured graphical interface based on the Qt and KDE widgets. This interface will allow a user to manage their own connections, as well as maintain all of the various configuration files. You shouldnt have to use a text editor to edit configuration files unless you really want to
- Documentation - Connection Manager will be completely documented, including man pages, a user reference guide, and an administrator reference guide.
- Packaging - every effort will be made to make Connection Manager easy to install. Packages will be provided for a variety of platforms.
- Internationalization - Connection Manager will be designed and built so that it will be easy to add support for different languages.

conn-close gives us possibility to get rid of entries in ip_conntrack about ESTABLISHED TCP connections that goes through our server.

conn-close script uses hping2 to send spoofed RST packets which will fool conntrack and cause specified connections to be considered by conntrack as closed (now these connections will be in ip_conntrack in CLOSE state), even though RST packets will be more likely discarded by destination host.

Information about connections is read of course from /proc/net/ip_conntrack.

Idea was taken from script seen somewhere on the internet.

Net::FreeDB2::Connection is a FreeDB/CDDB abstract connection class.

Net::FreeDB2::Connection is an abstract class to represent connections to FreeDB/CDDB servers. After a successfull connection, FreeDB/CDDB queries, reads etc can be made to obtain/provide information from/to FreeDB/CDDB databases.

CONSTRUCTOR

new (OPT_HASH_REF)

Creates a new Net::FreeDB2::Connection object. By default connect () is called to initiate the connection but see option no_connect. See the implementation for complements/restrictions.

Options for OPT_HASH_REF may include:

client_name

Mandatory option to name the connecting client software.

client_version

Mandatory option with the client software version string.

client_host

The hostname of the client. Defaults to &Sys::Hostname::hostname ().

client_user

The user of the client. Defaults to scalar (getpwuid ($>));

freedb_host

The FreeDB/CDDB host. Defaults to freedb.freedb.org.

freedb_port

The port on the FreeDB/CDDB host.

proxy_host

Proxy host.

proxy_port

Port on the proxy host. Defaults to 8080.

proxy_user

Proxy user name to use.

proxy_passwd

Proxy password to use.

no_connect

Do not call connect () during instanciation.

JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apples OS X.

Jack audio connection kit can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.

Gtk2::Ex::MindMapView::Connection is a Perl module to draw connections between view items.

HEIRARCHY

Glib::Object
+----Gtk2::Object
+----Gnome2::Canvas::Item
+----Gnome2::Canvas::Shape
+----Gnome2::Canvas::Bpath
+----Gtk2::Ex::MindMapView::Connection

SYNOPSIS

use Gtk2::Ex::MindMapView::Connection;

This module is internal to Gtk2::Ex::MindMapView. Connections are instantiated by Gtk2::Ex::MindMapView. This module is responsible for drawing the connecting lines between Gtk2::Ex::MindMapView::Items onto the canvas.

The Gtk2::Ex::MindMapView::Connection is an observer. It registers with the view items so that it may be notified when a view items state changes.

INTERFACE

Properties

arrows (string : readable / writable)

Indicates whether arrows should be drawn. Possible values are: none, one-way, and two-way.

predecessor_item (Gtk2::Ex::MindMapView::Item : readable / writable)

The item at which this connection starts.

item (Gtk2::Ex::MindMapView::Item : readable / writable)

The item at which this connection ends.

Methods

INIT_INSTANCE

This subroutine is called by Glib::Object::Subclass as the object is being instantiated. You should not call this subroutine directly. Leave it alone.

SET_PROPERTY

This subroutine is called by Glib::Object::Subclass when a property is being set. You should not call this subroutine directly. Leave it alone. Instead call the set method to assign values to properties.

connect

Connect the Gtk2::Ex::MindMapView::Connection to the items it observes.

disconnect

Disconnect the Gtk2::Ex::MindMapView::Connection from the items it observes.

Conn is a small C library used to easily build any kind of IPV4/IPV6 daemons or clients.
It allows a dynamic number of connections (limited by number or by RAM) and dynamic buffer allocation (for I/O).
Enhancements:
- This release fixes two important bugs discovered with Valgrind.

tcptunnel is a simple TCP tunnel written in Perl.

Also is a versatile tcp tunnel. The tcptunnel uses:
- tunnelling through a firewall or proxy
- redirecting tcp connections to other ports or machines
- debugging tcp connections in-place
- packet sniffing

The tcptunnel listens on local port < port > and when a connection is made it connects the other end of the tunnel as follows:
a) With no proxy specified, it connects the other end
to < srvport > on < srv >.
b) With a proxy, it connects to < srvport > on < proxy >.
It then directs the proxy to telnet to < srv >, and then it connects the ends of the tunnel.
