name
you chose in the list box and click the Load button to
initialize this particular configuration.

PuTTY may also be used to run some command residing on the remote server. After specifying
the command line you want to run, you will be asked for your account name and password, and
then the command you specified will execute. When it completes, your session will terminate,
and your window will either close or remain open depending on how you configure the session.

bottom. The following screen will be presented:

the
Open
button at the bottom of the dialog.
6. You will have to provide an account name and password in the terminal window to
complete the process.
