For most people a '''server''' is something on the internet you '''connect to''', and a client is something you connect from. That sort of view is mostly valid, but it breaks down a little when the server and the workstation are the same machine.
 
A couple of examples:
 
* When you connect to wiki.littlesvr.ca in Firefox:
** Firefox is the client, it's making the request for a web page
** The web server on wiki.littlesvr.ca is the server, responding the the request with the contents of the web page
* When you use your phone to check your school email:
** The email application on your phone is the client, making the request to get new email
** The school email server is the server, responding to the request with a list of new emails
 
Most of a Linux system administrator's work is done in a terminal, and most of that is done on remote machines. Few companies can afford to hire in-house administrators, and those that can afford it have too many machines to connect keyboards and monitors to. But everything is connected to a network.

* Create an account on ops345.ca for ssh practice
* The "server" concept
* Using ssh to control a remote Linux server
* Remote credentials don't need to match local credentials
* Permissions work the same way, they apply to the user who is logged in
* Practice with permissions on files you own and files you don't own
* Copy files between Linux machines using scp
* Copy directories
* Note how ownership applies to files transferred between systems
