Sourceforge’s ssh service is one of the best, even though it is free. The traffic speed is great too.

Using Putty on Windows 7

Generating a Key

Download Puttygen, the key generator for Putty from here.

Run Puttygen

At the bottom section for Parameters, choose key type as “SSH2-DSA” (Not SSH2-RSA)

Click on Generate Button

When prompted, move the mouse over the blank space to “generate randomness”

Enter [email protected] for the key comment

You can now enter a passphrase. Since I dislike having to type a passphrase every time I connect to Sourceforge, I omit the passphrase.

Save private and public keys after giving them suggestive names. Do NOT close Puttygen.

Visit the Key posting page on Sourceforge



You can see a listbox where you can type in. If you have previous keys listed, you can view them there.

In the box, click anywhere on the last line, press the |END| key, and hit |RETURN|

Go back to Puttygen, after hovering the mouse over the Box titled “Public key for pasting into OpenSSH authorized keys file”, right click and choose Select All, then Copy to clipboard.


Go back to the box in Sourceforge account, and paste the key on a new line. Do not hit |ENTER| at the end. Click on th “Update” button.

Your key has now been added. Now we can configure Putty.


Configure Putty

Download Putty from here

Open Putty

Go back to Session, and under Saved Sessions, type in a name for the session, like “sourceforge”, unless you want to configure your client each time.

Connection Keepalive (Optional)

While using an SSH connection over Putty, and waiting for long processes like a repo sync or a Rom compilation to be over, you may occasionally find that the session has automatically disconnected. Of course this could be due to your net connection. Occasionally it’s that the connection times out. The connection can be kept alive by the following:

Connection>Options controlling the connection>Seconds between Keepalives>20


Hit Open to get started, and accept the certificate if prompted.
