PuTTY is a powerful SSH/telnet program used to access your shell/maintenance account. The following instructions will show you how to configure PuTTY to connect to Panix.

Obtaining PuTTY

You can download PuTTY directly from the PuTTY downloads page. http://sourceforge.net/project/showfiles.php?group_id=21558

Before You Connect:

There are a few settings that need to be changed. Here is a screenshot of what you'll see when PuTTY first starts up:

PuTTY graphical
reference- initial
startup screen

The screen should now look like this:

PuTTY graphical
reference- second screen

Click the 'SSH' category on the left-side panel. You'll see this screen:

PuTTY graphical
reference- third screen

The screen should now look like this:

PuTTY graphical
reference- fourth screen

Finally, return to the 'Session' category on the left-side panel.

This final screen will look like this:

PuTTY graphical
reference- fifth screen

Establishing a New Connection:

Double click the name of the session you've just created, or highlight it and press the 'Open' button at the bottom. PuTTY will pop up a screen similar to this one:

PuTTY graphical
reference- sixth screen

All Panix host machines have a unique key fingerprint that can be checked upon the initial connection, to make sure the machine you're connecting to is in fact the real machine, and not a stolen session. Panix keeps a copy of all our shell machines' fingerprints for comparison here: Panix Public Key page

This is a one-time occurence. Once you tell PuTTY that the machine is valid, it will remember for future connections. However, since 'shell.panix.com' resolves to several different machines, over time, you'll be asked to accept several different keys. Best security practice is to check the key fingerprint on our Public Key page *each* time you are asked for it.

After accepting the key, you'll see a login prompt like so:

PuTTY graphical
reference= final screen

Enter your username, and your password at the subsequent 'Password: ' prompt. You'll be greeted by a 'Welcome to Panix' banner, and a shell prompt. Welcome to Panix!

For general UNIX shell help, please see the shell section of our main help pages.

Customizing PuTTY

PuTTY is extremely flexible. Essentially, anything not mentioned here can be tweaked at your leisure by clicking the various 'Category' headings on the left-side panel. This contains options for window size, font, specific keyboard settings, ability to setup SSH tunnels for other services, etc. PuTTY's homepage has a wonderful help section that describes each option at http://www.chiark.greenend.org.uk/~sgtatham/putty/docs.html

Remember that if you make a change to a session, you must return to the 'Session' category, and click 'Save' to make it permanent.
