In this article I want to show some use, not trivial, of ssh, but first:

What is SSH?

From Wikipedia:

Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. The two major versions of the protocol are referred to as SSH1 or SSH-1 and SSH2 or SSH-2. Used primarily on Linux and Unix based systems to access shell accounts, SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notablypasswords, in plaintext, rendering them susceptible to packet analysis.The encryption used by SSH is intended to provide confidentiality and integrity of data over an unsecured network, such as the Internet.

Webcam server on Linux 2

My guide on how to make a webcam server has had a lot of feedback and so I decided to give two other methods to achieve it with two different software webcam-server and ZoneMinder

Webcam-server is absolutely the easiest way to show on the net what is seen from your webcam, the software is very stable (I’ve just installed Ubuntu, and shows the date 2004) is based on Java and to make it work is enough to give these commands:

#> aptitude install webcam-server

#> export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

#> webcam-server

Now point your browser at localhost:8888 and see a snapshot of that seen from the webcam.

In these days all the new netbooks and most laptops have built-in webcam, or at least add one external costs very little, apart from the traditional use in video calls you can use our Linux box to create a monitoring device, it can be used to monitor your child while you are at another PC, or your pet while you are at work, or have a home-made video surveillance system for your properties.

To accomplish this we will use the software Motion, the software is present in many distributions, I will give commands using my Ubuntu 10.04.

Feature that made me choose this software is the ability to remain “asleep” until it detects a noise or movement, and then activates and records, plus the ability to define custom actions when it start (send an email, an sms , Etc.).
