This document describes how to attach modems to a Linux box and allow it to receive calls to connect users to the network. Its like being your own ISP (Internet Service Provider). If your Linux box is connected to the Internet, then the users will also be connected to the Internet. Your Linux box becomes a router. This is also known as RAS (Remote Access Services) in the Microsoft world. In the Linux world its called PPP (Point to Point Protocol).
Most Linux users are familiar with using GNU Wget to download single files by passing the URL as an argument to the wget command, but you can also use Wget with desktop applications. It requires a little preparation, but it's easy to integrate Wget with your favorite browser and other desktop applications. You can also use Wget in scripts to categorize batch downloads and make them fault-tolerant. Here's how to get Wget to sit up and beg for you.

qmail is a mail transfer agent that runs on Unix. It was more secure replacement for the popular Sendmail program. The author offered a $500 prize for the first person to publish a verifiable security hole in the latest version of the software.
This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt,and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.

Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely.

What is SIEVE?
SIEVE is a language created and used for mail filtering that broadens the filtering options generally provided by mail servers or Antispam/Antivirus applications. They work basically by comparing different keys using different comparators and comparison methods, against headers of a mail message. Based on the result of the comparison, you can apply different actions to the corresponding mail message, i.e. reject, discard, redirect, etc.
