OPENSSH-SERVER

SSH is program to login into remote computer in Network. You can have all accessibility when you logged into remote computer. This is done by Linux terminal. You can also login from Windows to Linux System but you must have the Public key and password of the remote System, but for Linux you just need password of remote system. As I mention in the  beginning of this blog SSH is a program from which you can login into remote System. But it is must that Remote System must have Openssh-server installed in its system.

You can read more about SSH program by typing “man ssh” on your Linux terminal, as shown below.

Fig :1

In above image you can see at left most corner is given “SSH(1)”, that 1 means its “Executable programs or shell commands”. In Linux there are different types of programs that run on Linux Terminal. For example there is one command that is “kill()” which can be use for two different purposes.

You can check program type by typing on terminal “man man”, it shows following output on terminal as below.

Fig : 2

As mention we must have Openssh-server on Remote system, following is an example for installing Openssh-server in your system.

For installing openssh-server:

    sudo apt-get install openssh-server

Fig :3

You can also download openssh-server(any package) instead of installing it for later use.

For downloading openssh-server:

        sudo apt-get download openssh-server

Fig:4

Now, to connect to remote System you have to type on your terminal,

          ssh -4 IP_Address_of_Remote_System

Fig:5

In above command I used “-4”, which indicate that it's a IPV4, for IPV6 use “-6”. When you'll try to login into Remote host, it will ask for the Remote account password for security purpose. After logged into Remote Host you can have all access to Remote host on your terminal. But for Administrative or root access you must know it's password. To access as Administrative or root you can switch to that account by typing on terminal:

      su account_name

It will ask you the password for the same account. After entering into that account you can have access as Admin or root.

Many times it happened that you login as Admin but you can't use some commands like poweroff . So for that purpose just try following command,

       sudo poweroff

Here, it will ask for the Admin Account password, type it and then you can use some of the root command easily.

Monect: Controller of your PC

In today’s era most of world’s population uses Smart phones. Using your Android to control your computer is a great way to interact with programs. Your phone can be used a track pad, or could be used to use a media player using custom controls. Monect lets you take things further by turning your Android device into all manner of peripherals.

 

Fig1: Monect

What Are the Options?

There are plenty of apps available in Google Player that let you use your phone or tablet as a wireless keyboard or mouse for a computer. Monect can be used in this way, but it also boasts a number of other options that cater to a variety of scenarios.

Fig2: Description of Monect

This free app can transform your phone into not only a mouse or keyboard, but also a joystick, gamepad, media controller and much more. It’s great for gamers, but options such as text transfer and presentation mode open up additional opportunities. There are two components to the tool, the Android app and the desktop server. A package containing both pieces of software can be downloaded from its Hotfile hosting page.

Fig3: Downloading Zip file

There’s no need to sign up for an account, just click the Regular Download button, wait for the timer to count down and then click the download link. You may see a warning from your browser or AV tool that the file is potentially harmful, but this is simply a case of over-zealousness in detecting a tool that is used for remote access.

Fig4:

You’ll need to extract the contents of the zip file and then launch the file named Monect-Host. You’ll probably find that your firewall kicks in and you’ll need to allow the program to make use of your network in order to continue.

Fig5: Security Alert Window

Getting Connected:

Assuming your phone and computer are connected to the same wireless network, it will take a matter of seconds to establish a connection.

On your phone or tablet, install a copy of Monect from Google Play, launch the app and then either type in the IP address of your computer and tap Connect, or tap ‘Search host’ to scan for and connect to your machine.  If you find that you are unable to connect, trying restarting Windows to ensure that the installation is complete.

Fig6:

Once connected, you’ll see that are no less than 12 different modes to choose from; in most cases it is fairly obvious what each one does, and each can be used in different ways.

Fig7: Modes

Controller Modes:

Touchpad mode turns your phone into a laptop-style track pad complete with a scroll bar to the right. In this mode you can also access 3D Mouse mode which enables you to move the cursor around by using your phone as a laser pointer.

Fig8: Touch Area

Typewriter keys, Function keys and Numeric keypad are all modes in which you can use your phone as a keyboard. This can be handy if your keyboard is broken and you need a temporary replacement, or you are using a laptop or keyboard without a number pad.

Fig9: Options(1)

In Text Transfer mode it is possible to type and prepare text on your phone and then send it to whatever application currently has focus on your computer.

Fig10: Options(2)

Switch to My Computer mode and you can browse the contents of your hard drive from your Android device. Folders can be easily navigated, and files can be opened remotely, or downloaded to your phone – just tap and hold to bring up the option menu.

Fig11: My Computer Mode

Things start to get particularly interesting for gamers in Race, Joystick and Shooter modes. The app takes advantage of your device’s built in gyroscope so that it can be used as a steering wheel, a more traditional joystick/gamepad or as a crosshair control for FPS games.

 

Fig12: Gaming Options

The remaining three modes, PowerPoint, Browser and Media mode are ideal for when your computer is connected to a larger screen, projector, or a TV. Each mode features the touchpad area and mouse buttons.

In each case there are task specific buttons at the top of the screen. So whether you are looking to control video playback from the comfort of your sofa, or you want to be able to browse the web on your TV without having to battle with a regular keyboard and mouse, Monect makes it easy.
