There is a feature in OpenSSH since v3.9 which allows multiple SSH connections with the same caracteristics (host, port, remote login) to be made through a single TCP connection. This is useful because you’ll have to authenticate only once, and besides the new SSH connections will be much faster to establish.

Quoting the RSYNC homepage : “rsync is an open source utility that provides fast incremental file transfer.”

To make rsync both secure and automated (i.e : non-interactive), you can use SSH as the transport and set up a key pair. This is what will be discussed in this post, along with a few improvements.

This post presents what is the attack known as “ARP Man in the Middle” which is basically a way for a malicious user to sniff network traffic on a fully switched network. If you don’t know this attack yet, go on reading.

If you got this virus (or know someone who did), and it is spreading to all of your MSN contacts with something like the following message :

hey How are you???? this is ur pic rite?!<br /> http://www.msn- gallery.com/gallery.php?user=some_nickname.jpg

or in French something like :

http://msn-friends. iquebec.com/?photo=some_nickname<br /> ta tof fais koi sur ce site :P

Then you can use the following article (there is a removal tool) to get rid of it : How to Remove MSN Virus Project 1/ Generic2.EXO / Backdoor.Generic3.SAT

XSS (Cross Site Scripting) are a kind of attacks which are fairly popular these days and could target anyone, but are not nearly well known from most people.

In this post, I’ll try to give a short explanation of what they are.
