Intro to Linux

1.   Review/discuss online Linux tutorial resources at www.lancom-tech.com

2.  Chapter 13 Stuff (Administrative Nitty Gritty)


• What function does the Slocate.cron task perform? Can you change the schedule
  to perform it once an hour, instead of once a day? 
  
  
• To schedule your own user cron job, enter the command _______.  See if you
      can schedule a cron job that will back up your user directory every hour to a folder on
      the mounted FAT partition. 
  
  
• AT and Batch are one-shot versions of the Cron scheduler. See if you can configure
      a one-time job (as root) that will shut down the network in exactly 2 minutes.
  
•  Examine the service scripts Jang refers to on p. 374-375 and the dmesg file.
  
  
•  The PS command can be used to identify and kill running Linux processes. Read Jang's
   example on p. 384 to kill an open Mozilla window.
  
  
• This link has another glossary of useful Linux commands.

3. Student Presentation

4. Linux Practical Application Exercises


• Work with Open Office, other GUI applications and command-line utilities,
  (ps2pdf, a2ps) to produce and view Adobe Acrobat-compatible (pdf) files.
  
  If a2ps isn't installed on your computer, download and install the package from
  rpmfind.net.
  
  To use a2ps to convert any file into a Postscript format, enter the command:
  a2ps filename -o filename.ps
  
  To convert the Postscript file into an Adobe PDF file, enter the command
  ps2pdf filename.ps

5.   Intro to Networking (See Chapter 20)

       a.  Two general categories for computer networks are _________  and __________.

       b.  Linux networks most commonly run on a network architecture called ____________

           (or __________________), which has three popular speeds,  __________,

            ________________, and _________________.

        To connect computers to the Internet, they must be configured to use the ______ protocol
        to connect them to a server or router provided by an ISP. (in most cases).  Common
        systems to connect computers on a local network to routers or servers on a wide area network
        include _________ connections, through a telephone line, faster _________ connections through
         
        a telephone line, _____________,  _____________, and ______________ connections.

        Each computer on the network must have a unique identification.   Numerical addresses
        are translated into alphanumeric names called ______________.    Single or grouped
        servers are identified by name and accessed over the World Wide Web through
        _______________.
         
        On Ethernet networks, each network adapter card is identified by a unique string called a 

        ______________________.   Electronic information is sent from computer to computer
 
        with these cards through a seven-layer system called ____________.  (See Jang, p.610 and
        this section of the MCMCSE Network + Study Guide.)

       Try this  OSI practice test.


6. Networking Challenges


• Turn off your firewall to eliminate some obstacles in the following exercises.
  
  
• Go to the Internet and Network Options. Examine the settings for File Sharing and
  Local Network Browsing. See if you can configure the LISA Daemon to allow
  you to drag files from a VNC desktop over the network to your local computer.
  
  
• See if you can configure your computer to allow basic Samba client functionality
  from a GUI Konqueror window and from a Terminal command line.
  
  
• The command to make a Samba connection from a terminal session is ____________
  
  
          _________________________________________________________________


See if you can configure your Linux home directory as a read-only shared folder visible
from a Windows XP client. (To do this, you may need to change the hostname for
your computer. )
