Configuration Utilities

These are scripts and configuration files used to manage the workshop machines. We use ssh public/private keys, ssh server allowing root access with keys only, and, a hosts file to start (DNS later). Here are the various files:

Scripts

• ​alive (uses nmap to check if each box is up. Can use monitoring tools later in the week)
• ​do (execute commands on remote machines)
• ​push (push files out to remote machines)
• ​firewall.sh (not necessarily used, but a sample of what you might consider using)

Config Files

• 01proxy (goes in /etc/apt/apt.conf.d/ to point PCs to apt-cacher repository on classroom NOC)
• hosts: (replaces /etc/hosts)
• ​pcs: (locate this in the same directory as the scripts)
