We’ve all been in a situation where a client calls you in a panic and they need something right away. Only problem is, the file they need is on your desktop at work or at home or… basically somewhere you’re not. Remote access can save you from trouble and offer a level of convenience like few other apps can.
Where To Start
There are tons of remote access applications out there, some free, some paid, closed source and open source. Previously, I used the free version of TeamViewer. That is, until they were hacked. So are there any decent applications that can just connect you without having to give up your email address? Thankfully, yes.
Remmina is awesome. However, it can be terrible if it’s not set up properly, or if you’re not quite sure exactly how to use it. I’ve learned the hard way, and hopefully I can share enough info to get you up and running in no time!
If you’re running Ubuntu, Remmina comes in the box. If not, you can grab the snap version by running this in the terminal:
sudo snap install remmina
Alternatively, you can grab the PPA like so:
sudo add-apt-repository ppa:remmina-ppa-team/remmina-next
sudo apt-get update
sudo apt-get install remmina remmina-plugin-* libfreerdp-plugins-standard
If later on, you feel like this wasn’t working for you, or you just want to uninstall everything, just run:
sudo apt-get install ppa-purge && sudo ppa-purge ppa:remmina-ppa-team/remmina-next
Once you’ve got Remmina on your machine, you should see a window that looks kinda like this:
Set up the Computer You Want To Access Remotely
On the computer you want to access remotely, your first step is to enable screen sharing.
By default, screen sharing is disabled, but for this to work, you’re gonna want to turn that on.
Now you should see the screen sharing options. You’ll want to allow others to access the screen, and prompt them with a password upon logging in.
Establishing A Remote Connection
Now, all you need to do is open Remmina on the computer you’ll be accessing FROM, and enter the IP address of your remote computer. This can be tricky if you’ve never done this before. If you’re at home and the computer you want to control is also at home, you’re more than likely on the same network. This is known as a local network connection. You can access your machine easily just by typing in its local IP address. However, if you try this from your local coffee shop wifi, it won’t work.
What’s My IP Address?
As mentioned earlier, there’s your public (external) IP address, and your private (internal) IP address. Which is which, and why does it matter? Your internal IP is used for local networks, like your home wifi that’s connecting your laptop, desktop, Chromecast, AppleTV, Roku, your friend’s phone, and your Alexa. All those devices have their own individual IP addresses, and are connected to your wireless router (wifi), that has its own public IP address, which is accessable over the internet.
Use your PUBLIC IP Address
The point of remote access is… being remote, AKA outside the network where your other computer is. So before you leave the house, go to whatsmyip.com and copy that address to your clipboard. This is your public IP address (hence, why you can just hit that website and it displays it to you).
Set Up Your Router
Paste the IP address you got from whatsmyip.com into your favorite browser. This will bring up the login page to your home router. If you’ve never seen this before, the username and password is typically printed on a sticker on the side or bottom of your router. Look for a button that says “Port Forwarding”. Find the computer that you want to connect to and create a new rule for it. Set your port number to 5900 and save.
Set Up the Remote Computer
You need to install a VNC server that will allow your remote computer to listen for incomming connections. You can do this by running:
sudo apt install vnc4server
Okay, back to Remmina. In the main window, select VNC from the dropdown at the top.
Next, type your IP from whatsmyip.com into the bar, and ending it with :5900. So, for example, yours might look something like this:
Next, you’ll be prompted for that password you set up earlier.
Then, badda bing, you’re looking at your remote desktop! You did it!
