Intro to Linux

1. Discuss Red Hat decision to discontinue personal versions of Linux after RH9 and
transition to open source model for Fedora

2. Review/discuss take-home quiz

3. 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 _________________.

   c. 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.

   d.  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
        _______________.

   e. Internet domain names were created to give an easy to use system to find services in something
       other than an IP address. The browser, itself, can identify a computer host through either the IP
       address or the domain name.; For instance, see if you can find the numerical address associated
       with www.yahoo.com ______________________. If you open a web browser and enter
       this IP address in the URL window, you should see the same result as when you enter the www
       domain name.

    f. Under the Domain Name System, there are six top-level domain extensions:

       ____ ____ ____ ____ ____ ____

      See http://netforbeginners.miningco.com/library/101/bl-domainnames.htm for a tabular list and
      http://www.learnthat.com/courses/computer/inet/network3.shtml for more information about
      the domain name system.

      Internet domain names are also called _____________________________________. These
      should no t be confused with the Microsoft domain terminology developed for Windows NT.
      Simple Microsoft workgroup and domain names are not visible over the Internet. They are
      similar to Linux hostnames, and are defined through a protocol called NETBIOS. With
      Windows 2000 Server, Microsoft added support for true Internet domain names.

   g.  On Ethernet networks, each network adapter card is identified by a unique string called a

        ____________. How can you find this string for the network card in your computer?

        _________________________________________________.

    h.   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.)

          OSI stands for ______________________________. Try this OSI practice test.

     i. The TCP/IP model for networking includes ___ layers. (See Jang, p. 613).

         Major protocols that work under the TCP/IP model include ____, _____,

         _____, _____, _____. (See Jang, p. 614 for a more complete list.)

         What are the TCP/IP transport-level protocols? _____ ______

         What are the TCP/IP network-level protocols? _____ ______

         What are the TCP/IP link-level protocols? _____ ______ ______ ______

         (See this link for more information.)

     j.  Define these TCP/IP network services:

         Domain Name System: ____________________________________________

          ______________________________________________________________

         Dynamic Host Configuration Protocol ________________________________

         ______________________________________________________________

       Address Resolution Protocol  _______________________________________

        ______________________________________________________________

    h.   Tp set up a computer on a TCP/IP network, you need ___________

           (manually assigned by an administrator or automatically assigned by ____,

           a ______  address and a ___________.   Additionally, to connect to sites on

           the Internet, you need ___________.

           The current standard in use for IP addressing is called ____.   IP addresses can

            be expressed in two formats ___________   and  __________.

           Addresses under  this standard are expressed in ___ columns with
            numerical values  between __   and ____.

      i.     IP addresses are divided into ___ classes.  (See Jang, p. 618.

              What class do the addresses on our classroom computers belong to? _____

           Do the classroom computers use public or private addresses?   _______

               How would you write the IP address of your classroom computer in binary notation?

                ___________________

         j.   Experiment with PING and IFCONFIG commands.   Change your adapter's IP address.  Check
               the graphic redhat-config-network application and see if the change carries over.

                Stop and restart the network using the Service [servicename] command.

                After making sure that your Sendmail server is disabled, change the hostname of
                 your computer, in preparation for the next set of exercises.

                 Review network mask settings (see Jang, p. 629). 

• 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 ____________
