Install, Configure and Use Remmina on Ubuntu
|
|
======
|
|
|
|
Remmina is an **open-source desktop client written in GTK** that lets you connect to remote computers.
|
|
|
|
It is a simpler alternative to tools like **AnyDesk** and **TeamViewer**. You can connect through various protocols like **RDP, VNC, SSH, X2GO, HTTP(S)** , and more. The feature-set can be extended with the help of available plugins if you need.
|
|
|
|
Note that Remmina is only available for Linux users. So, if you have a Linux machine and want to connect to any other remote system, Remmina is perfect.
|
|
|
|
I should also mention that it is one of the [best remote desktop tools for Linux][1].
|
|
|
|
![][2]
|
|
|
|
Now that you know about [Remmina][3] as a capable remote desktop tool. How do you use it?
|
|
|
|
Let me tell you more about it:
|
|
|
|
### Get Started by Installing Remmina on Ubuntu
|
|
|
|
![][4]
|
|
|
|
Remmina comes pre-installed in many Linux distributions, including the latest releases of Ubuntu and Fedora.
|
|
|
|
In either case, you can find it available in the official repositories for most Linux distributions.
|
|
|
|
If you want to install the latest version, I recommend installing the Flatpak or the Snap package.
|
|
|
|
For this article, I installed the [Snap package][5] from the Ubuntu's Software Center. You can choose to get the Flatpak package from [Flathub][6] as well.
|
|
|
|
📋
|
|
|
|
The entire setup is tested on and written for systems on the same subnetwork. In simpler terms, your devices should be connected to the same router.
|
|
|
|
### Using Remmina to Connect to a Linux Remote Machine (Ubuntu)
|
|
|
|
To test this use-case, I tried connecting to my Linux laptop from my Linux desktop computer.
|
|
|
|
Before connecting, you need to know the IP address of the remote system. In my case, I went to system settings and utilized the graphical user interface **Wi-Fi→ Connection settings** ( _gear icon next to the network connected_ ) to check the IP address.
|
|
|
|
![][7]
|
|
|
|
You can also use the terminal and type in the following to get the IP address:
|
|
|
|
```
|
|
|
|
ip a
|
|
|
|
```
|
|
|
|
![][8]
|
|
|
|
You might have more things listed here, but the IP address right to "inet" under an Ethernet connection (you can spot that by the text field link/ether) is what we need.
|
|
|
|
In my case, the IP address is **192.168.1.14**
|
|
|
|
Next, you need two more things before you can connect to the remote machine:
|
|
|
|
* Enable remote desktop in the remote system you wish to connect.
|
|
* The **username** and the **password** for remote connection.
|
|
|
|
|
|
|
|
#### Enable remote connection on the remote system
|
|
|
|
To get that, navigate through **Settings → Sharing → Remote Desktop**.
|
|
|
|
![][9]
|
|
|
|
Here, you need to toggle (enable) **Remote Desktop** , check " **Enable Legacy VNC Protocol** ", and then **Remote Control** as shown in the screenshot below.
|
|
|
|
![][10]
|
|
|
|
We utilize the **Virtual Network Computing** (VNC) protocol to connect, which is the preferred way to connect to Linux computers for most.
|
|
|
|
As you can notice, you can find the username and the password under the " **Authentication** " section in the image above.
|
|
|
|
Once you have the IP, authentication details, and enabled remote sharing, you just need to **add a new connection profile** and fill up the details.
|
|
|
|
![][11]
|
|
|
|
Here's how that looks like:
|
|
|
|
![][12]
|
|
|
|
You can give it any name, and create a Group (if you need). For instance, I can have a group of home devices from a workplace, and keep it organized separately to identify remote computers easily.
|
|
|
|
For the protocol, use " **Remmina VNC Plugin** ".
|
|
|
|
The rest of the settings remain default, and ensure that the Quality is set to **good**. So, you can have a good user experience without requiring a superfast internet connection.
|
|
|
|
However, you can choose to change it if you think you have poor network connectivity.
|
|
|
|
Once you are done with setting the options, hit " **Save and Connect** ".
|
|
|
|
Of course, if you want to connect to a machine once from a guest computer, and do not want to save the details, you can avoid saving and hit " **Connect** ".
|
|
|
|
![][13]
|
|
|
|
You might be prompted for the connection for the first time. If you do not want this, you can change the authentication technique to " **Require a password** " in the remote desktop settings:
|
|
|
|
![][14]
|
|
|
|
And, voilà! You are now connected to the remote system.
|
|
|
|
![][15]
|
|
|
|
📋
|
|
|
|
You should change the quality settings before connecting to a remote system to avoid crashes.
|
|
|
|
While you are connected to the remote machine, you can take a screenshot, scale the window size, duplicate the connection, and do several more useful things from the left sidebar.
|
|
|
|
Now, let us move on to a Windows system.
|
|
|
|
### Using Remmina to Connect to a Windows Remote System
|
|
|
|
Just like a Linux (Ubuntu in our example) system, you have to enable remote desktop sharing before trying to connect to a Windows computer.
|
|
|
|
💡
|
|
|
|
For Windows, you can only find the Remote Desktop option in the ****Pro editions****.
|
|
|
|
So, if you have Windows 10/11 Home edition, you cannot enable Remote Desktop unless you upgrade it to the professional edition.
|
|
|
|
Considering you have a license to Windows pro edition on your remote system.
|
|
|
|
Here's how to enable Remote Desktop sharing:
|
|
|
|
1. Head to **Settings → System → Remote Desktop**. Now, enable the option as shown below:
|
|
|
|
|
|
|
|
![][16]
|
|
|
|
You will get a prompt to confirm the action. Proceed with it.
|
|
|
|
![][17]
|
|
|
|
2. Next, we need information to connect to this Windows device. For that, you need to your network settings, and hit " **Properties** " to get network information (IP address).
|
|
|
|
In this case, we have a wired connection.
|
|
|
|
|
|
|
|
|
|
![][18]
|
|
|
|
On the next screen, you will have the IP address of your system as shown below:
|
|
|
|
![][19]
|
|
|
|
In case you have a wireless connection, you will have to navigate to " **Change adapter options** " in the network status screen and then right-click on the **Wi-Fi adapter** connected to your computer.
|
|
|
|
Now, check the status of the Wi-Fi network and click on " **Details** " to get the IP address, as shown in the screenshots below:
|
|
|
|
![Checking Wi-Fi network details on Windows][20]
|
|
|
|
For the tutorial, I used the wired connection. So, the IP address for me remains:
|
|
|
|
**192.168.1.3**
|
|
|
|
I created a new remote connection profile with the above IP address and its protocol as **RDP (Remote Desktop Protocol)**.
|
|
|
|
![][21]
|
|
|
|
![][22]
|
|
|
|
The username and password are the same as your Windows computer credentials.
|
|
|
|
For me, it was my Microsoft account credentials linked to my Windows system. If you do not have a Microsoft account linked, it will be your local username and password.
|
|
|
|
Of course, you can choose to add a new user just for remote desktop if you like.
|
|
|
|
Considering I accidentally entered the local credentials instead of my microso[[email protected]][23] details, it prompted me again for authentication.
|
|
|
|
![][24]
|
|
|
|
Once you are done authenticating, you will get another prompt asking you to verify the certificate where your desktop name will also show up as follows:
|
|
|
|
![][25]
|
|
|
|
Accept the certificate. If you are incredibly cautious about the connection, you can pick to view the installed certificates on your system and verify by following [Microsoft's documentation][26].
|
|
|
|
![][27]
|
|
|
|
And, that is it! You are connected to the Windows remote machine.
|
|
|
|
**One important bit here** : you should **enable the dynamic resolution update** from the sidebar to make the resolution adapt to your screen size.
|
|
|
|
![][28]
|
|
|
|
For the tutorial, I have tested a Linux remote machine and a Windows system, which are the two most popular use-cases.
|
|
|
|
You need a static IP and IP forwarding to test the SSH connection protocol.
|
|
|
|
For the rest of the options in the sidebar, you get re-sizing the window, taking a screenshot of the remote machine, duplicating a connection, tweaking the connection quality for slow/fast performance, and more.
|
|
|
|
### Wrapping Up
|
|
|
|
Remmina works well for simple remote desktop connection, with advanced abilities for users who require it.
|
|
|
|
You can customize your remote connection with advanced options and SSH connection. However, if you do not know what you are doing, you probably do not need those options.
|
|
|
|
_How else do you use the Remmina app for remote connections? Let me know in the comments below._
