UDOO Vision Documentation
Remote Terminal (SSH)
You can use UDOO VISION as a Desktop PC, connected to 4K or UHD monitors, keyboard and mouse. This is probably the most used setup, but if you want you can communicate with the board in remote way, so long as you leaving the board connected to a network.
Requirements
A first condition to establish a SSH connection with your UDOO VISION is to have previously completed the tutorial about Find IP Address.
A second condition is to install a SSH Server on your UDOO VISION system, and install an SSH Client on the PC from which you want to connect to UDOO VISION.
SSH Server on UDOO VISION
Choose the software for the OS you've installed on your UDOO VISION.
On a Linux system we suggest to use OpenSSH Server.
On Ubuntu/Debian/Linux Mint type the following command:
$ sudo apt install openssh-server
N.B: On Ubuntu you usually find the openssh-server already installed out of the box.
On RHEL/Centos/Fedora type the following command:
# yum -y install openssh-server
On ArchLinux type the following command:
# pacman -S openssh
You can change some OpenSSH server configuration in the file /etc/ssh/sshd_config.
Make a copy of the original sshd configuration file first.
sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.backup
sudo gedit /etc/ssh/sshd_config
Heads up! Take note of your Linux username and password. These will be required during the connection from the client.
If you want to use another SSH Server different from OpenSSh, you can find a comparison of SSH Server here.
On Windows you usually won't use the SSH connection to access a terminal, so we suggest to follow the docs on the next page to use a complete Remote Desktop (VNC) connection.
SSH Client on the remote PC
On the PC from which you want to connect to UDOO VISION choose the client for the OS you use.
On a Linux system we suggest to use OpenSSH Client.
On Ubuntu/Debian/Linux Mint type the following command:
$ sudo apt install openssh-client
N.B: On Ubuntu you usually find the openssh-server already installed out of the box.
On RHEL/Centos/Fedora type the following command:
# yum -y install openssh-clients
On ArchLinux type the following command:
# pacman -S openssh
Connection via SSH
Once you have completed these steps, open your SSH client. For the sake of this example, we consider you're using PuTTY on Windows.
Opening PuTTY a window will ask you to specify the destination you want to connect to.
In the first blank space, named Host Name or IP address, type the IP Address of UDOO VISION.
Eventually, a Windows Firewall popup could appear the first time you do this. If this happens, allow PuTTY to bypass the firewall.
When the connection succeeds, a black window will appear. That is the terminal.
It will ask you to enter your login credential. Type the name of the user
<username>@<IPAddress>' password:
Type the password of the username then press "Enter".
Heads up! Do not worry if you don't see what you type in the terminal: it's an expedient to hide your password to eventual onlookers.
At this point you can use your terminal:
