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

• first login as root@192.168.0.30 (or 192.168.5.1)

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