In order for Screens to be able to connect back to your Linux PC, it needs to be configured for remote access.
Enable Remote Desktop
Depending on your Linux distribution, configuration details may vary, but most modern Linux desktop environments typically provide a feature called Desktop Sharing or Remote Desktop.
Open these settings and configure the service using a configuration similar to that depicted in this screenshot.
Password Length
By default, Remote Desktop limits password length to eight characters. If you use more than eight characters, Screens will use only the first eight characters entered.
Optional: Installing a SSH Server
OpenSSH Installation
To install OpenSSH, open a terminal and run the following commands with superuser permissions.
For distributions using the apt package management system such as Ubuntu, Debian, or Linux Mint
$ sudo apt-get install openssh-server openssh-clientFor distributions using the rpm package management system, such as Red Hat Enterprise, CentOS, or Fedora
$ yum -y install openssh-server openssh-clientTesting the Connection
Before proceeding further, use the following Terminal command to confirm that your OpenSSH server is working properly.
$ nc -v -z 127.0.0.1 22Making your Computer accessible remotely
If you'd like to connect to your computer remotely, we recommend to use a service such as No-IP. You'll find instructions in this article.
