SSH (Secure SHell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet, rlogin and rsh. SSH encrypts traffic in both directions, preventing traffic sniffing and password theft. SSH also offers several additional useful features:
• Compression: traffic may be optionally compressed at the stream level.
• Public key authentication: optionally replacing password authentication.
• Authentication of the server: making ”man-in-the-middle” attack more difficult
• Port forwarding: arbitrary TCP sessions can be forwarded over an SSH connection.
• X11 forwarding: SSH can forward your X11 sessions too.
• File transfer: the SSH protocol family includes two file transfer protocols.

This proposal aims to create a module that implements the GData protocol specification in Drupal. The Google data APIs provide a simple standard protocol, called “GData”, for reading and writing data on the web using either of two standard XML-based syndication formats: Atom or RSS. This module will handle all the basic stuff a developer shouldn’t have to worry about when developing modules that extend its functionality such as data transfer, protocol adherence, and authentication. It will expose its own API which will allow other developers to create modules that easily interact with information provided by Google’s many service APIs. Using this module, module developers who need access to this information need only concern themselves with what’s important: the data.

One of the common requirements in a Linux-based network is to include Linux workstations. There are a multitude of ways to do so; if this network also includes Windows workstations that are connecting to the Linux file server, you’re likely already using Samba. This document describes how to have a Linux workstation access data on a Linux file server via Samba. Here’s a quick tutorial to the essential steps involved in setting up a Linux File Server and having Linux workstations connect to it, using Fedora Core as an example.

Peer-to-Peer programming (P2P) has in recent years become a widely explored research area. With the evolution of wireless technology such as mobile phones, the idea to bring these two technologies together gives a new dimension to P2P communication, collaboration and resource sharing.

The definition of Web 2.0 is still being debated despite extensive discussion. Its staunchest advocates proclaim it a complete philosophical and technological reworking of how the web functions. Others declare that it is meaningless. However, most agree on common characteristics of a Web 2.0 application, such as increased interactivity, the acceptance of user input for building community and a reliance on client-side functionality. Additionally, Web 2.0 applications can be more vulnerable to exploitation by hackers than their predecessors. Hackers spend most of their time gathering information. When Web 2.0 applications push functionality and code to users, they provide hackers with information that can be used for formulating attacks. Often, old attacks such as cross-site scripting become more dangerous when used against Web 2.0 applications. This white paper defines some of the common technological components of Web 2.0 applications and discusses ways of securing them against exploitation.

FTP (File Transfer Protocol) is a more reliable way of transferring your files over the internet as opposed to attaching to emails. FTP is more secure, quicker, and your files are not “coded” or “mimed” as there is no need to rely on your email server. Follow the instructions below to FTP your files to Colortech Graphics and Printing.

IFAXVIEW is a TIFF Viewer that allows you to view Internet FAX received on the PC as a Tagged Image File Format (”TIFF”) attachment to an email. The Internet FAX is a facsimile equipment connected to an Ethernet LAN (Local Area Network) that allows you to send documents over the Internet to a remote Internet FAX or a PC terminal. It also allows you to receive and print an email transmitted by a remote PC. The Internet FAX uses the Simple Mail Transfer Protocol (”SMTP”) for communication, which is the same internet protocol used for Electronic Mail (”email”).
