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.

You can read many other informations about the configuration of the server into the config.txt file located under /root onto the server. A printed version is near the server.

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 for manual operation
  • or use the automatic way pssh -h /root/schoolPcs.pssh /root/syncData.sh

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/school.sh
  • pssh -h cp -a /mnt/server/etc/school.sh /etc/profile.d/school.sh or synchronize data pssh -h /root/schoolPcs.pssh /root/syncData.sh
  • reload a new terminal (or reboot ?) on the school laptops
