Name: Damn Vulnerable Linux
Homepage: http://www.damnvulnerablelinux.org/
Brief description: Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn’t. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn’t built to run on your desktop – it’s a learning tool for security students.

Name: De-ICE
Homepage: http://heorot.net/livecds/ or http://www.de-ice.net
Brief description: The PenTest LiveCDs are the creation of Thomas Wilhelm, who was transferred to a penetration test team at the company he worked for. Needing to learn as much about penetration testing as quickly as possible, Thomas began looking for both tools and targets. He found a number of tools, but no usable targets to practice against. Eventually, in an attempt to narrow the learning gap, Thomas created PenTest scenarios using LiveCDs.

Name: NETinVM
Homepage: http://informatica.uv.es/~carlos/docencia/netinvm/#id7
Brief description: NETinVM is a single VMware virtual machine image that contains, ready to run, a series of User-mode Linux (UML) virtual machines which, when started, conform a whole computer network inside the VMware virtual machine. Hence the name NETinVM, an acronym for NETwork in Virtual Machine. NETinVM has been conceived mainly as an educational tool for teaching and learning about operating systems, computer networks and system and network security, but other uses are certainly possible.

Brief description: It's a linux virtual machine intentionally configured with exploitable services to provide you with a path to r00t. :) Currently, the virtual machine NIC is configured in bridged networking, so it will obtain a normal IP address on the network you are connected to. You can easily change this to NAT or Host Only if you desire. A quick ping sweep will show the IP address of the virtual machine.
