+Using a remote server for development is so much cooler for obvious reasons. Using MOSH on top of it naturally makes the experience much better.
+
+###[Koding.com](https://koding.com) + [MOSH](https://mosh.mit.edu/#getting) = *Ecstasy*
+
+
+Here is how you can get mosh to work on koding.com
+
+1. SSH into the koding server from your client machine. If you haven't added ssh keys yet checkout their [tutorial](http://learn.koding.com/guides/ssh-into-your-vm/). 
+    ```bash
+    ssh <username>@<username>.koding.io
+    ```
+
+2. Setup [uncomplicated firewall](http://learn.koding.com/guides/enable-ufw/) in the remote machine.
+    ```bash
+    sudo apt-get install ufw
+    sudo ufw status verbose
+    sudo ufw enable
+    ```
+
+3. Open up critical ports first viz. HTTP, SSH and 56789 for koding.
+    ```bash
+    sudo ufw allow ssh
+    sudo ufw allow http
+    sudo ufw allow 56789/tcp
+    ```
+
+4. Open up the port (60001 is used by mosh in most cases) on the remote machine for the client machine to access it via udp.
+    ```bash
+    sudo ufw allow 60001/udp
+    ```
+
+5. Connect the remote machine by running the mosh command from the client machine. This will automatically ssh into the remote server and start the mosh-server.
+    ```bash
+    mosh <username>@<username>.koding.io
+    ```
+
+That's it, you are done.
