Linux Tutorial

The terminal is the key instrument in each of its various Linux distributions available today. It is therefore very important to use it as convenient as possible.

Guake is a new way to bring up the terminal, allowing not only a convenient use of the same, even integration within a more pleasant workspace.

Once started, Guake can recall the terminal keyboard – using the F12 key by default – which is presented differently from how we used to. It is not the classic open window, but sort of semi-transparent layer that is placed on top of all windows that are open on the workspace, which is instantiated inside the terminal. In short, it is a sort of drop-down terminal that plugs from the top of the screen. In addition to providing support for tabs, Guake also has a series of pre-configured keyboard shortcuts that allow you to use it.

The application is widely configurable. First, you can choose the shell interpreter that you prefer to take lending itself well to different uses. In addition, you can manage other parameters like autoscroll, hotkeys and appearances including fonts used in graphics, color and background. Guake is available for several Linux distributions including Ubuntu, Debian, Fedora, Gentoo. To install under Ubuntu Guake the following command:

     sudo apt-get install Guake

Installing a Terminal Server on Ubuntu is now very simple: With the help of Open SSH and Neatx multiple users can share a Linux computer.

The solution takes for data transport protocol, the SSH (OpenSSH server), so the traffic is encrypted, the connection can take place even without concerns over the Internet. As a basis for our Linux Terminal Server is the Ubuntu Desktop Edition.

Installation
sudo apt-get install openssh-server
add-apt-repository ppa: freenx-team/ppa
sudo aptitude update
sudo aptitude install-server Neatx

Client: NX Client
to make the connection from a Windows computer on the NX client is required (by NoMachine) see: www.nomachine.com

through the connection is opened like Windows Terminal Services, a new session on the Linux box.

Open SSH Server
The connection is accepted by the Open SSH server
It is therefore necessary to start thinking about the SSH configuration:
proper use passwords, or possibly to allow only certain users from SSH server:

the following command to edit sshd_config with:
sudo gedit / etc / ssh / sshd_config
e.g. can
User2 user3 DenyUsers root user on the ssh server will be excluded.

Error “Internal error Exiting on signal: 15″
After several successful connections I had this error:
Internal Error:
Remedy on the client (FreeNX client):
Create a new session with a different name,

on the server or delete the following folder:
/ var / lib / Neatx / sessions
in Terminal
rm / var / lib / Neatx / sessions / *-r-f
I’ve row precaution integrated in my boot script.
