Using traffic tunneling over a SOCKS tunnel, especially through SSH, offers several benefits, like security, encryption and posibility to access services available from FZU internal networks only.
To configure Firefox to tunnel traffic over a SOCKS tunnel created by SSH, you can follow these steps:
¶ Create an SSH Tunnel
Open a terminal or command prompt on your local machine and use the following command to create an SSH tunnel with dynamic port forwarding:
ssh -D 1080 user@limba.fzu.cz
Replace user with your main (email) institute username, log in with your Kerberos password.
¶ Configure Firefox
Open Firefox and follow these steps:
¶ Access the Preferences:
- On Windows and Linux, click on the three horizontal lines in the top-right corner, then select "Options."
- On macOS, click on "Firefox" in the menu bar, then select "Preferences."
¶ Navigate to Network Settings:
- In the Preferences/Options page, select "General" on the left sidebar, scroll down to the "Network Settings" section.
¶ Configure Proxy Settings
- Click on the "Settings..." button next to "Connection."
- In the Connection Settings window, choose the "Manual proxy configuration" option
¶ Enter SOCKS Host
- In the "SOCKS Host" field, enter localhost as the host and
1080as the port (or the port you specified in the SSH command).
¶ Select SOCKS v5
- Choose "SOCKS v5" as the type of proxy.
¶ Configure No Proxy For
- You may want to add
localhost, 127.0.0.1to the "No Proxy for" field to prevent the SSH tunnel itself from being proxied.
