lightning: Login and File Transfer

Telnet is disabled on lightning for security reasons.  To login to lightning, you must
use the Secure Shell (ssh). Instead of issuing telnet lightning, issue ssh lightning.
The first time you do this on a machine, it will respond with 
"host key not found, generate hostkey?(yes/no)".  Answer yes.

ftp access into lightning is also disabled.  To copy a file into lightning, issue
the command scp file lightning:  . This will copy the file into your home
directory on lightning. It is also possible to ftp from lightning. This is much faster
than scp for large files.

ssh is available on any Project Vincent machine.  If you need to install
ssh on any non-Vincent Unix machine, you can obtain the tar file
ssh-1.2.27.tar and use the installation tools.  
You will need a C compiler and root access to install ssh.

If you would like to login or scp without using a password, this is possible.
Download the script nopasswd_login to the UNIX desktop
machine on which you want to use the password with no login, and then issue
ksh nopasswd_login

You will be prompted for your Lightning password twice, then you will no longer need
the password when you issue ssh lightning.its  or issue scp's from your
desktop to Lightning.
