Windows
Requirements
You will need:
- PuTTY with PuTTYgen and Pageant. A complete installer can be downloaded from [1].
- WinSCP or other SFTP client. WinSCP can be downloaded from [2].
Instructions
- Open PuTTYgen.
- Click 'Generate' to create a new key.
- Enter a passphrase.
- Save the Private key file. It should have an extension .ppk.
- Copy the public key from the text box, then close PuTTYgen.
- Open WinSCP or equivalent and connect to filmsoc.warwick.ac.uk. Login with your username and password.
- Open the directory .ssh (note the dot) or create it if it doesn't exist.
- Open the file authorized_keys for editing, or create a new file if it doesn't exist.
- Paste in your public key, making sure it is on a single line.
- Set permission on the .ssh directory to 0700 (rwx------) and on authorized_keys to 0600 (rw-------)
- Close WinSCP or equivalent.
Usage
- Open Pageant: an icon should appear in the system tray.
- (Right-)click the icon and select add key.
- Open your private keyfile and enter your passphrase when requested.
Programs such as PuTTY, WinSCP, bzr, etc. should automatically detect the loaded key and use that for authentication - just supply your username where relevant.
Troubleshooting
Okay, so I can't get this to work. If you succeed, please answer following;
- Does the paste string for authorized_keys need bits removing from each end?
