files in this repo

  • linux_perimissions.md - (Example file in /home/alice inside the VM) - explains some basics about linux file permissions
  • linux_commands.md - provides some basic Linux commands

OVA image

An ova image is a virtual machine image that is designed to run inside a hypervisor (like virtualbox). In order to use it on your home machine, you can download the OVA file from here.

If you are in the lab, you should NOT download this file directly, instead use the setup-ova.sh script which will download it into temporary storage (/tmp/).

This will let you use linux commands in bash, change permissions and see the effects.

Technical details

For those of you intrested in the machine setup:

  • The virtual machine is a Debian Jessie image, initially setup with 1GB of ram.
  • It has no desktop envrioment installed (is command line only).
  • It has an ssh server running
  • It has been configured with two network interfaces (eth0 and eth1)

username password groups
root password42 root
alice password42 alice, csee
