Tor 0.2.1.6-alpha (Testing branch)
10-13-2008
Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

LO(4) BSD Kernel Interfaces Manual LO(4) NAME
lo -- software loopback network interface SYNOPSIS
pseudo-device loop DESCRIPTION
The loop interface is a software loopback mechanism which may be used for performance analysis, software testing, and/or local communication. As with other network interfaces, the loopback interface must have network addresses assigned for each address family with which it is to be used. These addresses may be set or changed with the SIOCSIFADDR ioctl(2). The loopback interface should be the last interface configured, as protocols may use the order of configuration as an indication of priority. The loopback should never be configured first unless no hard- ware interfaces exist. The loopback interface lo0 is created at boottime, it always exists and cannot be destroyed with ifconfig(8). Additional loopback interfaces can be created by using the ifconfig(8) create command. DIAGNOSTICS
lo%d: can't handle af%d . The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped. SEE ALSO
inet(4), intro(4), ifconfig(8) HISTORY
The lo device appeared in 4.2BSD. BUGS
Previous versions of the system enabled the loopback interface automatically, using a nonstandard Internet address (127.1). Use of that address is now discouraged; a reserved host address for the local network should be used instead. BSD
