hpc-class: Login and File Transfer

Telnet is disabled on hpc-class for security reasons.  To login to hpc-class, you must
use the Secure Shell (ssh). Instead of issuing telnet hpc-class, issue ssh hpc-class.
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 hpc-class is also disabled.  To copy a file into hpc-class, issue
the command scp file hpc-class:  . This will copy the file into your home
directory on hpc-class. It is also possible to ftp from hpc-class. 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.

For Microsoft Windows based machines, ssh is available as part of the advanced
Scout Kit.
