If you're on Linux, we recommend Remmina, which comes with many distributions already, and also has SSH capabilities for Linux and RDP for Windows machines.
Quick Start for those who wear Ferrari cologne.
An example of what to put into the Cyberduck application
Detailed Guide for everyone else.
Cyberduck allows you to upload and transfer files to your machine in Ronin using SFTP. You'll be able to drag and drop files from your desktop to either a Linux or Windows machine.
SFTP stands for Secure File Transfer Protocol, and it's exactly that. Secure meaning encrypted, and encrypting things helps prevent baddies from spying on what you're doing.
Lets get started
Download and install Cyberduck from here. For most users, the default installation options are OK.
Step 1 - Start Cyberduck and click Open Connection.
Step 2 - Enter your login details.
At the Cyberduck login screen, select SFTP from the top drop down, then enter your machines address into the Server section.(if you've forgotten it - it can be found on the Machine Summary screen highlighted below. Or write it on a sticky note next time!)
Step 3 - For Linux Machines only
The default username for an Ubuntu machine is "ubuntu" and there is no password.
A list of default usernames can be found here
Next to the SSH private key section, click Choose and add your .pem key you set up when you created your Linux machine to Cyberduck.
SSH keys work similar to real world keys, so whoever has a copy of your key has full access to your machine, so be really careful where you store it and who you give it to!
Step 3 - For Windows Machines only
The default username for a Windows machine is "Administrator" and the password is the same as the password entered when creating the machine.
There are different default usernames for all different Operating Systems. For example, R Studio default username is "r-studio".
Step 4 - Login and drop files.
Click the Connect button in Cyberduck window to connect.
After the connection is established, you will be able to click and drag your files from your desktop straight to this machine!
For first time connections, you will be asked if you trust this machine. To add the host fingerprint to the host cache, and stop this dialog from popping up constantly, check the Always box shown below and click Allow
