Hopefully, we will not add too many of these just because we have a file for them now... svn:r9155 --- address-spec.txt | 61 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 address-spec.txt (limited to 'address-spec.txt') diff --git a/address-spec.txt b/address-spec.txt new file mode 100644 index 0000000..c1af2e0 --- /dev/null +++ b/address-spec.txt @@ -0,0 +1,61 @@ +$Id$ + + Special Hostnames in Tor + Nick Mathewson + +1. Overview + + Most of the time, Tor treats user-specified hostnames as opaque: When the + user connects to tor.eff.org, Tor picks an exit node and uses that node to + connect to "tor.eff.org". Some hostnames, however, can be used to override + Tor's default behavior and circuit-building rules. + + These hostnames can be passed to Tor as the address part of a SOCKS4a or + SOCKS5 request. If the application is connected to Tor using an IP-only + method (such as SOCKS4, TransPort, or NatdPort), these hostnames can be + substituted for certain IP addresses using the MapAddress configuration + option or the MAPADDRESS control command. + +2. .exit + + SYNTAX: [hostname].[name-or-digest].exit + [name-or-digest].exit + + Hostname is a valid hostname; [name-or-digest] is either the nickname of a + Tor node or the hex-encoded digest of that node's public key. + + When Tor sees an address in this format, it uses the specified hostname as + the exit node. If no "hostname" component is given, Tor defaults to the + published IPv4 address of the exit node. + + It is valid to try to resolve hostnames + + EXAMPLES: + www.example.com.exampletornode.exit + + Connect to www.example.com from the node called "exampletornode." + + exampletornode.exit + + Connect to the published IP address of "exampletornode" using + "exampletornode" as the exit. + +3. .onion + + SYNTAX [digest].onion + + The digest is the first eighty bits of a SHA1 hash of the identity key for + a hidden service, encoded in base32. + + When Tor sees an address in this format, it tries to look up and connect to + the specified hidden service. See rend-spec.txt for full details. + +4. .noconnect + + SYNTAX: [string].noconnect + + When Tor sees an address in this format, it immediately closes the + connection without attaching it to any circuit. This is useful for + controllers that want to test whether a given application is indeed using + the same instance of Tor that they're controlling. + -- cgit v1.2.3-54-g00ecf
