I want to be able to access one of my Ubuntu computers from a Linux computer, from within my Home Network, but for it to be impossible to do so from outside.



What would be the best way to go about this?



Thanks in advance!

          Secure Shell is one choice that is fairly easy but it only allows for a Command Line Interface (CLI). SSH can be accessed from the WAN by port forwarding in your router settings.



          Remote Desktop is easy and available natively on Ubuntu machines. The instructions to set it up can be found at the following page.
          http://www.makeuseof.com/tag/ubuntu-remote-desktop-builtin-vnc-compatible-dead-easy/



          You need to go into Desktop Sharing Preferences and allow others to view your Desktop and allow other users to control your desktop. You can set a password under security if you so desire.



          After you find the IP address you can use Remmina Remote Desktop client to access it from that machine. You can use ifconfig to determine the IP address. When you open Remmina it should look similar to the picture below. However it will auto-populate with RDP, you will need to change this to VNC.enter image description here



          Remote Desktop can also be accessed from WAN by forwarding the port, but if this isn't setup you won't have access. One thing to check is to make sure that you are using VNC not RDP as your protocol to connect.



          On the machine you want to connect from you will need to make sure that Remmina is installed and properly.
          In Ubuntu/Debian:



          sudo apt-get install remmina remmina-plugin-*


          In Centos/RHEL:



          yum install remmina remmina-plugin-*


          In Fedora:



          sudo dnf copr enable hubbitus/remmina-next
          sudo dnf upgrade --refresh 'remmina*' 'freerdp*'

          • With SSH you would have to go into your router settings and allow connection from outside. I don't believe that Reminna allows any access from outside the LAN. Scratch that, it can as well but like SSH it has to be set up in your router settings.

          • When using Remmina, it keeps saying Unable to Connect, even though I think I am doing everything correct. I have all the settings like in the link you sent, but it won't work.

          If you are familiar with terminal, you can use ssh. Simply install on the machine you want to control package openssh-server.



          On your local machine open terminal and type ssh login@internal_ip_of_your_remote_machine. Some networks even work with hostname (login@hostname.local).



          If you want to skip logging in all the time, you can create and copy your public authentification key:



          ssh-keygen - if you have already not generated your ssh key (you can confirm everything)



          ssh-copy-id login@remote_machine and enter remote password.
          From now on you can login from your computer without password query.

            With SSH you would have to go into your router settings and allow connection from outside. I don't believe that Reminna allows any access from outside the LAN. Scratch that, it can as well but like SSH it has to be set up in your router settings.

            When using Remmina, it keeps saying Unable to Connect, even though I think I am doing everything correct. I have all the settings like in the link you sent, but it won't work.

            @nullmeta That didn't change anything.

            If you are familiar with terminal, you can use ssh. Simply install on the machine you want to control package openssh-server.



            On your local machine open terminal and type ssh login@internal_ip_of_your_remote_machine. Some networks even work with hostname (login@hostname.local).



            If you want to skip logging in all the time, you can create and copy your public authentification key:



            ssh-keygen - if you have already not generated your ssh key (you can confirm everything)



            ssh-copy-id login@remote_machine and enter remote password.
            From now on you can login from your computer without password query.
