Generating SSH Keys for SFTP/SSH (FileZilla, Cyberduck, Dreamweaver, etc.) | Information Technology and Computing Support (2024)

This guide only applies to Windows 11 and newer versions of Windows 10 (build 1809+). For older versions of Windows, please follow the instructions under "Using PuTTY" or check Microsoft's website on how to enable OpenSSHClient for Windows.

Steps

1. Open the Command Prompt app

2. At the command line prompt, type ssh-keygen -t rsa
3. You will then be asked to choose a save location for the keys. You can choose the default by pressing enter. Then hit enter two more times to skip creating a passcode.
4. Still in the terminal paste the following command:type %UserProfile%\.ssh\id_rsa.pub | ssh [email protected] "cat >> .ssh/authorized_keys. This will publish your public keytothe engineering servers. If you saved the key to a location other than the default, replace %UserProfile%\.ssh\id_rsa.pubwith this location, such as C:\Users\your_username\.ssh\my_key.pub.
5. Enter your password. You will be presented with a Duo two-factor prompt. Enter 1 and press enter. This will send a request to your Duo Mobile app which you will need to accept

6. Test your SSH Keys bytypingssh [email protected] -i%UserProfile%\.ssh\id_rsaat the terminal command line prompt. If you saved the key to a location other than the default, replace %UserProfile%\.ssh\id_rsawith this location, such as C:\Users\your_username\.ssh\my_key. If successful,you will connect without having to enter a password or do two-factor authentication!

Using your SSH Keys with FileZilla

1. First, downloadFileZilla (available here)

2. Open FileZilla and go to File->Site Manager

3. Create a New Site and name it "access"
4. To the right in the General Tab, Select SFTP for the Protocol and enter the Host as access.engr.oregonstate.edu.
5. For Logon Type select Key file, enter your username for User, and then browse to the location of your `id_rsa' file. You may have to change the dropdown to "All files (*.*)" in the File Explorer window to show your "id_rsa" file.

6. Click Connect at the bottom and you should now be connected to Flip without the need of two-factor authentication!

Generating your SSH Key

1. Launchthe mac terminal.app (/Applications/Utilities/Terminal.app)

2. At the command line prompt, type ssh-keygen -t rsa
3. You will then be asked to choose a save location for the keys. You can choose the default by pressing enter. Then hit enter two more times to skip creating a passcode
4. Still in the terminal, type ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]. This will publish your public key to the engineering servers.
5. When prompted enter your password
6. You should now see the two-factor Duo authentication. Enter 1 to send a push to your Mobile Duo app
7. Test your SSH Keys bytypingssh access.engr.oregonstate.eduat the terminal command line prompt. If successful,you will connect without having to enter a password or do two-factor authentication!

Using your SSH Keys with Cyberduck(https://cyberduck.io/)

• LaunchCyberduck and click the Open Connection button
• Set connection type to `SFTP` in the dropdown menu
• Set the server to "access.engr.oregonstate.edu"
• Enter your ONID username
• Do not enter a password and change SSH Private Key from `none` to the location of your `id_rsa` file. If you followed the default settings it should already be listed without needing to browse
• Finally click the Connect button and you will be logged in without the need for a password or 2-factor authentication

Using your SSH Keys with Adobe Dreamweaver

Dreamweaver does not like the the SSH Key format generated by the latest version of OpenSSH and the ssh-keygen untility. If you are running a recent version of macOS, including Mojave. You will need to "downgrade" your id_rsa file using the folloing command in the Terminal app:

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

Now continue to set up Dreamweaver:

• From the Dreamweaver site menu, select "Manage Sites":

• Select the remote site connection you want to use SSH Keys with andthen click the pencil icon underneath:

• Next select "Servers" in left hand pane, and the existing server configuration to the right:

• Configure as seen below, navigating to the ssh key file at /Users/[yourUserName]/.ssh/id_rsa
  ([yourUserName] is YOUR mac login name)

For this you will need:

• PuTTY (availablehere)
• FileZilla (available here)

Steps

1. Open up PuTTYGen, click "Generate," and follow the on-screen instructions
2. Once the key is generated, you will need to save the public key

Save it to a location you will be able to easily find it and name itid_rsa.pub

3. Now you need to save the private key

Ignore the warning about the passcode. Save it to the same location as before and name itid_rsa.ppk

4. Using PuTTY, log ontoaccess.engr.oregonstate.eduand enter your password when prompted
5. You will be presented with a Duo two-factor prompt. Enter1and press enter. This will send a request to your Duo Mobile app which you will need to accept.

6. You are now logged ontoaccess.engr.oregonstate.edu
7. If the directory.sshdoes not exist, execute the commandmkdir .sshfollowed bychmod 700 .ssh
8. Use your favorite command text editor (mine is emacs) to open up~/.ssh/authorized_keyswhich should be an empty file. If it does not exist, create it
9. From the PuTTY Key Generator windowcopy the key as shown in the image below. Make sure you copy the entire string.

10. Back in the editor onaccess.engr.oregonstate.edupaste the copied public key and save the changes

11. You now need to set permissions on the file. In the putty window, typechmod 600 ~/.ssh/authorized_keys
12. Back in PuTTY, you want to create a Saved Session you have not done so already
13. In Host Name enter[email protected]

14. Below in the Saved Sessions field enterflipand click Save

15. Click Connect->SSH->Auth->Credentials on the sidebar

16. On this screen, Browse to the location of your private key file: id_rsa.ppk. Now click the Open Button at the bottom

17. You should now be logged onto Flip without needing to provide a password OR two-factor authorization

18. Now we need to set up FileZilla
19. Open FileZilla and go to File->Site Manager

20. Create a New Site and name it "access"

21. To the right in the General Tab, Select SFTP for the Protocol and enter the Host as access.engr.oregonstate.edu

22. For Logon Type select Key file, enter your username for User, and then browse to the location of your `id_rsa.ppk' file.

23. Click Connect at the bottom and you should now be connected to Flip without the need of two-factor authentication!
