Installing and configuring PUTTY for use with HSEAS hosts
Putty is a Secure Shell client for Windows (98/ME/NT/2000).
It is a telnet-like connection that is much more secure - your password
never transits the network in the clear (as it does with telnet),
as the connection is encrypted. Here's how to use putty.
Take the binaries/executables and place them in a directory to keep
them nice and safe. Then right-click the main binary
and drag it to the desktop. You will be asked if you want to copy it,
move it, or make a shortcut - select the latter.
This makes putty convenient to use, but also keeps the executable a
little safer from being accidentally deleted.
- Now double-click (left mouse button) the Putty icon.
This will open up the putty configuration window.
In the left-most pane of the window, click on the item marked Session.
- In the right-hand pane, near the top, enter the
for the configuration you are about to create.
Use the full name of the host (the FQDN name, e.g.,
- Below that entry, select SSH
as the protocol to use.
- Now give the session a name in the
Session Name dialog box; I usually use the short name of the host,
- Make sure the
Close Window on Exit
checkbox is checked.
- Over in the left-hand pane of the window, select

(leave blank if more than one person will be using this machine), and the
Minutes between keep-alives should
be set to 0.
- You may wish to go to the Window/Colors item in the left-hand pane,
and set your preferred colors for background, foreground (i.e., the text)
and cursor (etc.).
- You're almost done. Select
again from the left-hand pane, verify that the right hand pane contains
information that is correct, and then click the
- If you wish to configure other hosts, you can Load a saved session,s
alter the relevant settings, make sure you use a different session name,
and then save that new session (i.e., configuration).
- In using Putty, double click the putty icon, then select
and then click on the saved session you wish to use, then click on
and then on
Putty will open a telnet-like window to the host.
- The first time you connect to a host, putty will warn you that
the host does not have a stored key - that is OK. Accept that.
Worry if it is a host that you have already connected to.
Occasionally, putty (the client) and the remote host (the ssh server)
will not negotiate their key comparisons correctly.
Try again. Occasionally, server software may think you are not who
and will drop the connection. Try again.
There can be a lag between the
window opening, and you being able to type anything,
and you will not see
a prompt for your password.
Wait and be patient - the two hosts are
negotiating a lot of public/private key stuff that is
