Saguaro is accessed using ssh, a secure system that provides interactive shell (command line) access, file transfers, and X-Windows tunneling. Linux, UNIX, and Apple OS X systems include an ssh client named ‘ssh’. Windows users must install a client. Suggested clients are ASU site-licensed client (then search for ssh), PuTTY, or OpenSSH.
Shell Access is accomplished by connecting to the login node from your system with a command like
or using a graphical client.
File Transfers can be done using
or
.
works like the
or
commands, but allows you to copy files to a remote system. To copy a file to Saguaro using
, use a command like,
replacing filename with the name of the file to copy, and username with your username. Please notice the ‘:’ at the end of the command, this is what tells
that you are copying to a remote system.
With this command files will be copied to your home directory on Saguaro. To copy to other directories, append the directory path to the command line after the ‘:’. For example,
will copy files to the
directory in your home directory. If the command were
the file will be copied to
on Saguaro. This is probable NOT what you want, so be careful.
is used like
, but over the secure ssh connection. Many people prefer graphical
clients for transferring files.
Graphical Access with X-Windows can be done by using ssh to
tunnel the X-Windows session back to your workstation. Linux and UNIX
systems use X-Windows for their graphical environment. Apple OS X users
will need to install and run the X11 program that comes with OS X.
Windows users will need to install a X-Windows server like Exceed, the
ASU site-licensed one available through http://myapps.asu.edu/. Alternatively, there is a free server called Xming.
Once the X-Windows server is running, just
to connect, then run the application you need. If your workstation is
properly configured, the application will then appear on your desktop.
A good application to test with is
, which provides a shell in a window.
