What is PuTTY?
PuTTY is a simple application which can be used to connect securely from a Windows PC to a Linux (or Unix) system. The latest version can be downloaded from here.
How do I use it?
Before you start you need to know the hostname or IP address of the system you will be connecting to. In most cases it will be gate.stats.ox.ac.uk .
- Double click on the PuTTY icon.
- The PuTTY Configuration window will appear.
- Enter the hostname in the "HostName (or IPaddress)" box. Make sure that SSH is selected.
- You may see a PuTTY security alert like this:
- If you are using gate.stats.ox.ac.uk this alert appears if you haven't downloaded our SSH keys.
- A login window appears. Enter your Statistics username and password.
- Use logout or exit to finish your session.
Running X applications from a PuTTY session
It can be convenient to use PuTTY and Exceed to run X applications. This is usually quicker than using Exceed to connect to an Exceed server and is more flexible because any public access Linux PC can be used. For home laptop users we recommend xming rather than Exceed.
What do I need to run this?
- PuTTY v 0.53b or later. To check the version open PuTTY and click on the About button.
- Exceed v 7.1 or later. The current version is v.10.
- Start Exceed with All Programs -> Hummingbird Connectivity 10 -> Exceed. This will start Exceed in passive mode.
- Open a PuTTY window. Enter the hostname in the "HostName (or IPaddress)" box but do not click on Open yet.
- Click on X11 on the Category box on the lefthand side. A window like this appears:
- Check the "Enable X11 forwarding" box and click on Open.
- A login window appears. Enter your Statistics username and password. A simple test that X applications can be displayed is to use the xclock & command. A clock should appear on your desktop.
- Use logout or exit to finish your session. If you have open X applications then you should exit from these in order to complete the logout process.
- The Exceed session can now be closed.
