• Because the computers are on a network, they each have a unique identification.
• Each machine has a name, for example one of the machines is called ‘claymore.engineer.gvsu.edu’. The short form of this name is ‘claymore’. The machine also has an equivalent number ‘148.61.36.215’.
• you can log into other machines. Try ‘rlogin ws1’. This allows you to sit at one machine, and use many others, even around the world.
• you can also use a number of other commands which will allow network access,
rusers look at other users on the network
who look at who is logged into your machine
last a list of the last users logged in
• You can also access other computers with public access directories using the ‘ftp’ command. For example try ‘ftp 152.2.22.81’. This will connect you to a computer some place in the U.S. When it asks you for your ‘login name’ type ‘anonymous’. When it asks for a ‘password’, enter your name. You may now move around using ls, pwd, cd, etc. If you want to get a file from some directory, type ‘binary’, then type ‘get filename’. ‘quit’ ends everything.
