Starting an Existing PuTTY Session
This section describes how to start a PuTTY connection which has been created
and saved before.
Procedure
Step 1
Start PuTTY by double-clicking the
putty.exe
file, or by clicking the
icon if you have created a desktop shortcut.
Step 2
Double-click the session you want to open from the Saved sessions
list. If this is a session with an IP address already defined, PuTTY will
automatically establish the connection.
If you are using SSH to connect to an NE for the first time, the follow-

This message is displayed to warn you about a possible network
attack known as spoofing. Spoofing is when your connection is
secretly redirected to a different computer, so that you send your
password to the wrong machine. The SSH protocol prevents such
attacks by requiring that each server supporting SSH has a unique
identifying code; a host key. If PuTTY registers a host key that differs
from the expected one, the server may have been switched and a
spoofing attack may be in progress.
However, when you connect to a server you have not connected to
before, PuTTY cannot know whether the host key is the right one or
not. So it displays the warning shown above, giving you the task of
deciding whether to trust this host key or not.
Step 3
If you are sure that this is the right NE, select [Yes]. If not, select [No].
[Yes]
