Linux Terminal Server Project(LTSP)for Dummies
2
Why set up LTSP?

• Open source
• Cheaper to
• set up
• update
• run
• Re-use, recycle obsolete computers
• You can do it!!!

3
What do you need?

• Server
• Terminal
• Switch or Hub
• Software

Server Hardware Requirements

• The power is dependent upon
• The number of terminals
• Applications installed.
• The minimal requirements for 3 terminals are
• Pentium III 500
• 512 megs of ram
• 20 gig hard drive
• Note this is for basic applications like
  OpenOffice and Mozilla (web browsing)

5
Terminal Hardware Requirements

• LAN card ( preferably with a boot chip socket)
• If no boot chip
• Floppy drive
• CD Rom
• Hard Drive
• USB port
• DONT DO THIS!!!

6
Switch or Hub

• Need as many hubs as you have terminals one for
  the server
• Not this type of hub!!!

Hardware Set Up

• Connect the system together
• Connect the server to any port on the switch or
  hub, except the uplink port.
• Connect the terminals to the other hub ports,
  except the uplink port.
• Look for a green light indicating a successful
  connection!!!

Adding Users

• Go to Applications gt System Settings gt Users and

• Uncheck create a private group for the user
• Click OK
• Repeat for each terminal/student adding on (eg.
  User02, user03)
• This allows for each user to have their own
  storage space on the server, regardless of number
  of terminals
• eg. You can have 40 students with their own
  passwords for 15 terminals
