SSH stands for Secure Shell. This is a cryptographic network protocol that's used for operating network services securely over an unsecured network. An SSH key is a way of connecting and authenticating yourself to networks.

My typical setup for a development box in VirtualBox uses two NICs. The first uses NAT to allow the box to communicate with the outside world through my host computer’s network connection. (NAT is the default, so shouldn't require any setup.) The second is a "host-only" connection that allows my host and guest to interact.
To create a host-only connection in VirtualBox, start by opening the preferences in VirtualBox. Go to the "Network" tab, and addd a Host-only Network. Modify the host-only network, and disable DHCP. Make a note of the IP address. (Feel free to set the IP address as well, if you like.)
Next, assign this host-only adapter to the virtual machine. Select the VM and press "Settings". Go to the "Network" tab, and select "Adpater 2". Enable the adapter, set it to a "Host-only Adapter", and select the adpater you created above.

| Undercover communication | |
| It should be obvious by now, that the only way to communicate | |
| stealthily and securely is to avoid raising suspicion to the | |
| level at which the authorities might consider it worthwhile | |
| to put you under active surveillance (e.g., park a van with | |
| TEMPEST equipment by your apartment). |
This guide may assume some very basic programming knowledge, but not necessarily python. It aims to give anyone enough knowledge to start diving into data problems themselves by using these techniques, and tries to explain (fairly comprehensively) everything that is going on for the newcomer.
This guide will be covering several different topics and should equip you with enough knowledge to try some of what you read out on real problems.
| ### Basic Scanning Techniques | |
| * Scan a single target | |
| * `nmap [target]` | |
| * Scan multiple targets | |
| * `nmap [target1,target2,etc]` | |
| * Scan a list of targets | |
| * `nmap -iL [list.txt]` | |
| * Scan a range of hosts | |
| * `nmap [range of IP addresses] |
