How to set up and use secure remote control to access lubuntu computers.

Instead of writing the whole process, I would like to provide a link that helped me to figure out an easy way to set up this. Basically, it will allow you to connect to your computer across a local network or internet with secure shell and vnc viewer. (It's all done using the terminal, ut vnc clients probably have ssh feature so you do not have to enter terminal again and again.).

Here is a link.

Here is a couple of useful notes(you should read the guide first:

• If you are using normal Ubuntu distro, it should have a vnc client called Remmina. If you enter apprpriate details as well as activate ssh tunnel (it's in ssh tab and enter relevant details there), you do not have to use terminal at all. However, if you do not activate ssh, you will still be able to connect to your desktop without secure layer. Here is a second note about the issue...
• If you do not want to use ssh tunnel, but to connect to remote desktop without entering a password, just disable the ssh on your client and you do not have to provide password in the settings as well. However, if you want to secure the computer that you are accessing, you need to set up a password in the vino preferences (or desktop sharing, which bring it to a third note).

•  In the guide, it will say to use 'default desktop application' (or something like that) but you wio't find it lubuntu 14.04. It's actually called 'Default applications for LXsession' and you can find it in Preferences. Once you click on it and wait till it updates its database, you will find the desktop sharing feature, which can be chosen by selecting a checkbox, by pressing on 'Autostart' button and look through a list. Remember to restart for the desktop to take effect.

How to set up a static IP address on Ubuntu Desktop Edition.

Note: This tutorial applies to desktop version of Ubuntu (in this case I am showing example in lubuntu, but other variants should work as well). If you develop a ubuntu server, I refer you to Ubuntu Server documentation to set static IP address.

Hello guys, after wasting an hour to find a way to set the static IP address in my machine, I figured out the cause of the problem. If you've read 'Setting up static address' in ubuntu server documentation, you know that you can do that by writing stuff to a file. However, it will not work in Desktop Edition of Ubuntu, because there is an application called 'network-manager' that keeps the same configurations and prevents the written configurations to be applied for static addressing.

So, in order to set a static IP address, you need to enter your details into that program. Usually, you will find it in settings and it's (usually) named Network Connections.

 


After finding the application, you should be able to see a list of ethernet interfaces (including wifi) and double-click on appropriate one or select one and press 'Edit'.

 



Once you've done that, you will see property tabs. Click on 'IPv4 Settings'

 


You should see a drop down list next to 'Method:' and select 'Manual'. Then you will notice that you will be able to add an address to the list. Enter appropriate settings. Remember that Gateway is a point where you can access the internet (e.g router) and Netmask is the one that usually facemask of IP addresses. Usually it looks like 255.255.255.0, but you have to check it yourself. Furthermore, DNS server is usually the same as Gateway address if you have a home router.



Once information is entered, save it and restart the computer. Now your computer should have the static IP address.

Note: Since I showed this example in Lubuntu, you should be able to find the same or similar settings on different variants of ubuntu.
