These are my links for 11 feb 2010 through 12 feb 2010:

• pwnat – NAT to NAT client-server communication – pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect.

• Unix File and Directory Permissions and Modes – Unix and Linux systems (including Mac OS X and other POSIX compliant systems) have a (relatively) simple system for controlling access to files and directories. This system is defined in POSIX.1:2008 standard external link, also known as the Single Unix Specification (SUS version 4). And since devices such as disks, ports, etc. have file names (under /dev) you control access to them the same way. (Note Windows systems up through Windows ME don't support permissions, just a "read only" attribute.)
