Login

Once you have an account on a central machine you may login  from any connected terminal. If you have to buy a terminal for your office first refer to the "CN Terminal Co-ordination Service - A User Guide" available at the UCO. This will help you choose the type of terminal you might wish to purchase. Note that at the present time, the use of X terminals is recommended rather than simple dumb ASCII terminals.

The following are some ways that you can access a UNIX system:

• Log into the workstation console directly (in other words, it is on or under your own desk). Consult the instructions for your workstation.
• Connect to it from another UNIX platform or from a VMS platform with Multinet or similar TCP/IP support installed:

   
                 		  telnet   host  or
  
                 		  rlogin   host
  
  

• Access the system from a terminal server  that supports IP or LAT; at CERN it will almost certainly be a DECserver. This means when you power up your terminal you have a prompt of some sort, for example Local>. Enter SHOW SERVICES to tell if the system you want to connect to is known by that terminal server. By simply typing

   
                 		  c dxcern
  
  

  you will be connected and be able to login (to node dxcern in this example).
• Access a UNIX system from an X terminal : for this discussion, it is assumed that you have successfully initialised and booted your X terminal. For help in this, see the CERN X Terminal Admnistrators Guide available at the UCO Self Service or via WWW (see entry UNIX Workstation Support on the CERN Computing Home Page). From an NCD X Terminal as normally installed at CERN, call up a Telnet window (Option Terminals on the Option Menu) and enter the name of the desired UNIX system and then select Connect.

The system will prompt for your login name and password.

Remember that UNIX is a case sensitive environment and so MYFILE, Myfile and myfile are three different filenames and FRED, Fred and fred are three different login names. Note, if you do use upper case to log in, UNIX may assume you have an upper case only terminal and you will have very limited capability. If you do so, either logout and log back in again or enter the command " stty -lcase".
