Here comes the notes and examples to administrate the school computers:

Then have in mind that /school/ is the master data repository. This directory is exported on school laptop (using /mnt/server mountpoint).

Pssh is available and can send data in mass over the school laptops. use pssh -h /root/schoolPcs.pssh youCommand withArgs

Laptop are x86_64 linux machines

If you want to copy some data onto the school laptop

  • copy your data into /school/data/TheGoodDirectory using ftp/scp/sftp from a machine onto the server
  • tell students to copy the data into their homedir from /mnt/server/data/TheGoodDirectory

If you need to install a missing package

  • pssh -h /root/schoolPcs.pssh yum install -y gsl.i686

Modify environment to add a software

  • edit /school/etc/
  • pssh -h cp -a /mnt/server/etc/ /etc/profile.d/
  • reload a new terminal (or reboot ?) on the school laptops
