Lab #2


Things to do

Things to do

  • Today’s Notes

    • NFS in the lab

    • Lecture:

      • Linux II

      • vi

    • Lab 2


Nfs in the lab

NFS in the lab

  • NFS allows the users home directory to be available no matter which workstation in the lab they log onto

  • The users home directory must always be available to keep Linux running

    • Contains critical configuration information

      • Do a ls –a to see all the configuration files for a user (starting with a .)

  • NFS allows the users home directory on a network drive!

    • This is a problem when the workstation’s NICs are disconnected for experiments

  • Special setup for the 302 lab:

    • When logging on a template of the user’s home directory is copied to the local workstation

      • This includes the Desktop (and others)

    • User’s home directories are deleted every midnight on the workstations!

    • Special case: network_storage directory is kept on the file server

      • Data there should follow you to each workstation you log on

      • Should not be deleted by the system


Lab 2

Lab 2

  • Objective

    • More Linux Basics

    • Introduce to vi


Important note

Important Note

  • Whenever possible text data must be captured as text, not with a screenshot

    • e.g. to document the contents of a directory:

      • ls –l > targetfile.txt

        • > creates or replaces data in targetfile.txt

        • targetfile.txt will have the listing normally sent to the screen

    • or

      • ls –l >> targetfile.txt

        • >> appends data to targetfile.txt

        • targetfile will have the listing added to the previous contents of the file
