SSH back door

Many times I'll be at a site where I need remote support from someone who is blocked on the outside by a company firewall. Few people realize that if you can get out to the world through a firewall, then it is relatively easy to open a hole so that the world can come into you.
In its crudest form, this is called "poking a hole in the firewall." I'll call it an SSH back door. To use it, you'll need a machine on the Internet that you can use as an intermediary.
In our example, we'll call our machine blackbox.example.com. The machine behind the company firewall is called ginger. Finally, the machine that technical support is on will be called tech. Figure 4 explains how this is set up.

Here's how to proceed:

How to find or remove the Virus ?

How to find or remove the Virus ?
If you’ve let your guard down–or even if you haven’t–it can be hard to tell if your PC is infected. Here’s what to do if you suspect the worst.
Heard this one before? You must run antivirus software and keep it up to date or else your PC will get infected, you’ll lose all your data, and you’ll incur the wrath of every e-mail buddy you unknowingly infect because of your carelessness.
You know they’re right. Yet for one reason or another, you’re not running antivirus software, or you are but it’s not up to date. Maybe you turned off your virus scanner because it conflicted with another program. Maybe you got tired of upgrading after you bought Norton Antivirus 2001, 2002, and 2003. Or maybe your annual subscription of virus definitions recently expired, and you’ve put off renewing.
It happens. It’s nothing to be ashamed of. But chances are, either you’re infected right now, as we speak, or you will be very soon.

Ubuntu 11.10 (Oneiric Ocelot) Officially Released [Download]

So after lots of Rumors about the new upcoming update of Ubuntu, Finally they've released the new Ubuntu 11.10 (Oneiric Ocelot) update for Public. Ubuntu is a Linux distribution for your desktop or server, with a fast and easy install, regular releases, a tight selection of excellent packages installed by default, every other package you can imagine available from the network, and professional technical support from Canonical Ltd and hundreds of other companies around the world.

The naming of Ubuntu 11.10 was announced on 7 March 2011 by Mark Shuttleworth. He explained that Oneiric means "dreamy", and it was scheduled to released today and now finally it's here so users can now download it.

It's also to update you that Ubuntu 11.10 does not include the classic GNOME desktop as a fall back to Unity, unlike Ubuntu 11.04 Natty Narwhal. Instead, 11.10 includes a 2D version of Unity as a fallback for computers that lack the hardware resources for the Compiz-based 3D version. Ubuntu 11.10 runs as a shell for GNOME 3 on top of GNOME 3 libraries, unlike in Ubuntu 11.04 where it ran as a shell for GNOME 2. Moreover, users will also be able to install the entire GNOME 3 stack along with GNOME Shell directly from the Ubuntu repositories, to be presented with a "GNOME 3 desktop" choice at login.
There also have been many changes made to Unity, including the placement of the Ubuntu button on the Launcher instead of on the Panel, the autohiding of the window controls (and the global menu) of maximized windows, the introduction of more transparency into the Dash (and the Panel if the Dash is opened), and the introduction of window controls for the Dash
