Configuration for lab machines running Ubuntu 12.04 "Precise Pangolin"

Eclipse

  • To run a Java web project on a local Tomcat server, use the console command tomcat7-instance-create, then define a new Server → Apache → Tomcat v7.0 Server in Eclipse

Επόπτης

  • Staff can use the Epoptes management interface by running it on the server: remote-epoptes
  • Only student logins start the Epoptes client and can be remote-controlled

Known Issues

Blank screen after logging in

  • First, wait another minute, especially when logging in for the first time
  • Press Ctrl-Alt-Del and select "Log out", then Ctrl-Alt-F1 and log in to the terminal
  • Run rm -rf .gconf to remove the .gconf folder
  • logout of the terminal, press Ctrl-Alt-F7, and log in normally

Installing Additional Packages

  • Edit /etc/MEET/packages.yaml
  • Reboot to trigger /etc/cron.daily/meet-packages

Installation Prerequisites

  • Machine MAC address must be added to server config /etc/dhcp/meet-lab.conf (the MAC address is displayed during the first step below)
  • After updating this file, restart DHCP: service isc-dhcp-server restart

Automatic Network Installation

  • Boot from the network by rebooting and holding down F12
  • If the machine's MAC address was added to /etc/dhcp/meet-lab.conf, you should see the "Erase & Install" screen
  • Press Enter to begin
  • For a first-time dual-boot installation:
    • You should see the option to "resize partition #2 and use freed space" -- make sure it reads "partition #2"
    • Choose this option
    • Continue, then enter a new partition size of 100 GB
    • The installer should confirm: partition #5 as ext4 & #6 as swap
  • For a dual-boot re-installation:
    • Do not choose the option to resize partition #5
    • Choose "Manual"
    • Go down to the line with "#5", press Enter
    • Select "Use as", and select "Ext4"
    • Go down to "Format the partition" and press Enter to switch to "yes"
    • And for "Mount point", select /
    • Select "Done"
    • Go down to "#6", press Enter, and "Use as" "swap area", then "Done" -- yes, even though swap was already selected
    • Select "Finish partitioning"
    • The installer should confirm: partition #5 as ext4 & #6 as swap
  • And for a Linux-only installation, choose "use entire disk"
  • At the end of the installation, reboot
