.. warning:: SSH host identification may have changed on the server you are trying
          to connect to. Please see our help guide on `SSH Errors <https://www.cs.uky.edu/docs/users/ssh.html>`_

.. attention:: Passwords for the *cs.uky.edu* domain are the same as your LinkBlue password.

.. important:: *cs.uky.edu* is synonymous with *cs.engr.uky.edu*. You can use either. 

.. important:: As of January 2021, a connection to the campus VPN is required to use the servers in the Multilab.
               In order to use the `campus VPN <https://www.uky.edu/its/phone-internet-services/connecting-vpn>`_ 
               you must `request access <https://uky.service-now.com/techhelp?id=kb_article&sysparm_article=KB0012723&sys_kb_id=afcc200adbe8101088933ede7c9619b8>`_.
               VPN access is typically granted immediately, more information about the VPN can be found 
               `here <vpn.html>`_. If further assistance is needed, please contact the `ITS Help Desk <https://www.uky.edu/its/>`_. 

**Things to remember**


1. In order to access these machines remotely, you must use an *ssh* client and be connected to the campus VPN.

2. Your login is the 'username' part of your LinkBlue email address. For
example, if your email address is *csst222@uky.edu*, your login name is
*csst222*. See the `list of servers <multilab.html#list-of-multilab-servers>`_.

3. Your CS email address is *youruserid@cs.uky.edu*. The default mail
configuration uses `~/.procmailrc` files. We initialize your *~/.forward* file to forward
your CS email to your campus email address. You can remove
the *~/.forward* file, but then the mailer delivers your email to your MultiLab
account.

4. If you would like to set up a web page on the CS systems (accessible as
*http://www.cs.uky.edu/~youruserid/*), follow these steps from a Linux
terminal:

.. code-block:: shell

    chmod 711 ~
    mkdir ~/HTML
    chmod 711 ~/HTML

Place your web-page files in *~/HTML/*. The home page must be named *index.html*.
All your web-page files must be publicly readable.

**PHP scripts**

You can install PHP files in your HTML directory with the *.php*
extension.  The web server executes these files with YOUR user privileges.  Be
careful.  PHP files should NOT be world readable, because they may contain database passwords
that can be accessible via the filesystem.  They should be executable by your
user id.

Executable/CGI programs need to be named with *.cgi* extension and follow the same rules as PHP files.
