What is PuTTY?
PuTTY is a windows program that is used to log in to other computers via the SSH-protocol. For example the servers at ACC.
Where do i download PuTTY?

Check our link page for the homepage of PuTTY.

When PuTTY is downloaded, save it somewhere where you easily can find it, for example the desktop.

Logging in
Start and settings

Start PuTTY by double clicking the PuTTY-icon .

  1. Enter the name of the computer to which you wish to connect in the field Host Name.
  2. Choose SSH as the protocol (the port number will change by it self)
  3. Click Open to connect.
If you want to save these settings for future connections to the same machine, enter a descriptive session name in the dialog below "Saved Sessions" and click Save before clicking Open.
First login

At the first login, a dialog similar to this will appear:

All computers that uses the SSH-protocol has an uniqe identifyer, called an SSH-key (host key). This is a warning that says that WinSCP don't recognize the key that it recived from the server. It therefore asks if you want to save it for future reference. If you don't press Yes, the key will not be saved and the connection will terminate.

It's recomended to press Yes.

Other time of login

You can also get a similar dialog other times:

If you know that you've already saved the key, the server has probably sent your client an other key this time. The common reasons for this is:

If you are sure that it's the correct machine, select "Yes". If not, select "Cancel".

If the machine you are trying to connect to is one of ACC's servers, contact support if you are unsure.

The login-prompt

When the application says login as:, enter your username at ACC. The application will then ask for your password as well. Enter when prompted.

If the username and password are correct, you will be logged in.

Logging out

Log out by entering exit in the command shell.

You can also log out by closing the window, although this can cause problems with some programs, that don't get to shut down correctly (for example mail readers).
