A New Internet Computer is
a PC-like device which allows the user to run applications and view information
hosted on other computers. Running a version of Linux under the covers, it
is a low-cost way to browse the web, read and send email and connect to other computers
with Kerberos, ssh
or telnet. It has an X-server
to allow it to display graphical applications running on other computers,
and a client to enable it to connect to a Windowstm
terminal server. The NIC has no hard drive of its own.
After obtaining a ticket (necessary for logging in to machines at FNAL),
you may use the SSH or telnet icons to access another machine.
If you have not been told otherwise, use fnalu.fnal.gov as your FNAL
host. Enter the correct information, check the push kerberos tickets
box if appropriate (eg you're logging in to a lab machine), and then hit
the OK button. If you have a kerberos ticket and you're logging on
to a fnal.gov machine, you should not be asked for a password. If you are,
your ticket is invalid for some reason: try to kinit. DO NOT TRY TO GIVE YOUR KERBEROS PASSWORD TO SSH:
it will not work. See the Problems
or Kerberos/AFS section of
the BooNE Computing Resources page
or the official FNAL Strong
Authentication page for possible solutions to your problem.
You may lock the screen to return to it later by starting the kxlock
application in the X-Terminals folder. However, you MUST have a valid Kerberos ticket otherwise you
will be unable to unlock the screen and must reboot the terminal!
Double-click on the kdestroy icon in the X-Terminals folder
to destroy your Kerberos tickets after you have logged out of all hosts
that require it.
DO NOT FORGET TO DESTROY YOUR TICKET
BEFORE YOU LEAVE THE TERMINAL!
