21) <H2>DESCRIPTION</H2>
22) 
23) <I>tor</I>
24) 
25) is a connection-oriented anonymizing communication
26) service. Users choose a source-routed path through a set of nodes, and
27) negotiate a &quot;virtual circuit&quot; through the network, in which each node
28) knows its predecessor and successor, but no others. Traffic flowing down
29) the circuit is unwrapped by a symmetric key at each node, which reveals
30) the downstream node.
31) <P>
32) 
33) Basically <I>tor</I> provides a distributed network of servers (&quot;onion
34) routers&quot;). Users bounce their TCP streams -- web traffic, ftp, ssh, etc --
35) around the routers, and recipients, observers, and even the routers
36) themselves have difficulty tracking the source of the stream.

54) If set, we will not advertise more than this amount of bandwidth for our
55) BandwidthRate. Server operators who want to reduce the number of clients
56) who ask to build circuits through them (since this is proportional to
57) advertised bandwidth rate) can thus reduce the CPU demands on their
58) server without impacting network performance.

59) <DT><B>ControlPort </B><I>Port</I><DD>
60) If set, Tor will accept connections from the same machine (localhost only) on
61) this port, and allow those connections to control the Tor process using the
62) Tor Control Protocol (described in control-spec.txt).  Note: unless you also
63) specify one of <B>HashedControlPassword</B> or <B>CookieAuthentication</B>,
64) setting this option will cause Tor to allow any process on the local host to
65) control it.
66) <DT><B>HashedControlPassword </B><I>hashed_password</I><DD>
67) Don't allow any connections on the control port except when the other process
68) knows the password whose one-way hash is <I>hashed_password</I>.  You can
69) compute the hash of a password by running &quot;tor --hash-password
70) <I>password</I>&quot;.
71) <DT><B>CookieAuthentication </B><B>0</B>|<B>1</B><DD>
72) If this option is set to 1, don't allow any connections on the control port
73) except when the connecting process knows the contents of a file named
74) &quot;control_auth_cookie&quot;, which Tor will create in its data directory.  This
75) authentication methods should only be used on systems with good filesystem
76) security. (Default: 0)

80) Every time the specified period elapses, Tor downloads a directory.
81) A directory contains a signed list of all known servers as well as
82) their current liveness status. A value of &quot;0 seconds&quot; tells Tor to choose an
83) appropriate default. (Default: 1 hour for clients, 20 minutes for servers.)

84) <DT><B>DirServer </B><I>address:port fingerprint</I><DD>
85) Use a nonstandard authoritative directory server at the provided
86) address and port, with the specified key fingerprint.  This option can
87) be repeated many times, for multiple authoritative directory
88) servers. If no <B>dirserver</B> line is given, Tor will use the default
89) directory servers: moria1, moria2, and tor26.
90) <DT><B>Group </B><I>GID</I><DD>
91) On startup, setgid to this user.
92) <DT><B>HttpProxy</B> <I>host</I>[:<I>port</I>]<DD>
93) If set, Tor will make all its directory requests through this host:port,
94) rather than connecting directly to any directory servers.
95) <DT><B>HttpsProxy</B> <I>host</I>[:<I>port</I>]<DD>
96) If set, Tor will make all its OR (SSL) connections through this host:port,
97) via HTTP CONNECT, rather than connecting directly to servers.

98) <DT><B>HttpsProxyAuthenticator</B> <I>username:password</I><DD>
99) If defined, Tor will use this username:password for Basic Https proxy
100) authentication, as in RFC 2617. This is currently the only form of
101) Https proxy authentication that Tor supports; feel free to submit a
102) patch if you want it to support others. You may want to set FascistFirewall
103) to restrict the set of ports you might try to connect to, if your Https
104) proxy only allows connecting to certain ports.

108) <DT><B>Log </B><I>minSeverity</I>[-<I>maxSeverity</I>] <B>stderr</B>|<B>stdout</B>|<B>syslog</B><DD>
109) Send all messages between <I>minSeverity</I> and <I>maxSeverity</I> to
110) the standard output stream, the standard error stream, or to the system
111) log. (The &quot;syslog&quot; value is only supported on Unix.)  Recognized
112) severity levels are debug, info, notice, warn, and err.  If only one
113) severity level is given, all messages of that level or higher will be
114) sent to the listed destination.
115) <DT><B>Log </B><I>minSeverity</I>[-<I>maxSeverity</I>] <B>file</B> <I>FILENAME</I><DD>
116) As above, but send log messages to the listed filename.  The &quot;Log&quot;
117) option may appear more than once in a configuration file.  Messages
118) are sent to all the logs that match their severity level.

121) to adjust this. (Default: 1024)
122) <DT><B>OutboundBindAddress </B><I>IP</I><DD>
123) Make all outbound connections originate from the IP address specified.  This
124) is only useful when you have multiple network interfaces, and you want all
125) of Tor's outgoing connections to use a single one.
126) <DT><B>PIDFile </B><I>FILE</I><DD>
127) On startup, write our PID to FILE. On clean shutdown, remove FILE.
128) <DT><B>RunAsDaemon </B><B>0</B>|<B>1</B><DD>
129) If 1, Tor forks and daemonizes to the background. (Default: 0)

130) <DT><B>SafeLogging </B><B>0</B>|<B>1</B><DD>
131) If 1, Tor replaces potentially sensitive strings in the logs
132) (e.g. addresses) with the string [scrubbed]. This way logs can still be
133) useful, but they don't leave behind personally identifying information
134) about what sites a user might have visited. (Default: 1)
135) <DT><B>StatusFetchPeriod </B><I>N</I> <B>seconds</B>|<B>minutes</B>|<B>hours</B>|<B>days</B>|<B>weeks</B><DD>
136) Every time the specified period elapses, Tor downloads signed status
137) information about the current state of known servers.  A value of
138) &quot;0 seconds&quot; tells Tor to choose an appropriate default. (Default: 30
139) minutes for clients, 15 minutes for servers.)

171) <DT><B>FascistFirewall </B><B>0</B>|<B>1</B><DD>
172) If 1, Tor will only create outgoing connections to ORs running on ports that
173) your firewall allows (defaults to 80 and 443; see <B>FirewallPorts</B>).  This will
174) allow you to run Tor as a client behind a firewall with restrictive policies,
175) but will not allow you to run as a server behind such a firewall.

180) A list of ports for services that tend to have long-running connections
181) (e.g. chat and interactive shells). Circuits for streams that use these
182) ports will contain only high-uptime nodes, to reduce the chance that a

216) For each value in the comma separated list, Tor will track recent connections
217) to hosts that match this value and attempt to
218) reuse the same exit node for each. If the value is prepended with a '.', it is
219) treated as matching an entire domain. If one of the values is just a '.', it
220) means match everything. This option is useful if you frequently connect to
221) sites that will expire all your authentication cookies (ie log you out) if
222) your IP address changes. Note that this option does have the disadvantage of
223) making it more clear that a given history is
224) associated with a single user. However, most people who would wish to observe
225) this will observe it through cookies or other protocol-specific means anyhow.
226) <DT><B>TrackHostExitsExpire </B><I>NUM</I><DD>
227) Since exit servers go up and down, it is desirable to expire the association
228) between host and exit server after NUM seconds of inactivity. The default

237) The following options are useful only for servers (that is, if <B>ORPort</B> is non-zero):
238) <DL COMPACT>
239) <DT><B>Address </B><I>address</I><DD>
240) The IP or fqdn of this server (e.g. moria.mit.edu). You can leave this
241) unset, and Tor will guess your IP.

243) Administrative contact information for server.
244) <DT><B>ExitPolicy </B><I>policy</I>,<I>policy</I>,<I>...</I><DD>
245) Set an exit policy for this server. Each policy is of the form
246) &quot;<B>accept</B>|<B>reject</B> <I>ADDR</I>[<B>/</B><I>MASK</I>]<B>:</B><I>PORT</I>&quot;.
247) If <B>/</B><I>MASK</I> is omitted then this policy just applies to the host
248) given.  Instead of giving a host or network you can also use &quot;<B>*</B>&quot; to
249) denote the universe (0.0.0.0/0).  <I>PORT</I> can be a single port number,
250) an interval of ports &quot;<I>FROM_PORT</I><B>-</B><I>TO_PORT</I>&quot;, or &quot;<B>*</B>&quot;.
251) <P>
252) For example, &quot;reject 127.0.0.1:*,reject 192.168.1.0/24:*,accept *:*&quot; would
253) reject any traffic destined for localhost and any 192.168.1.* address, but

259) See RFC 3330 for more details about internal and reserved IP address
260) space. Policies are considered first to last, and the first match wins. If
261) you want to _replace_ the default exit policy, end your exit policy with
262) either a reject *:* or an accept *:*. Otherwise, you're _augmenting_

311) <B>RedirectExit</B> options can be used: once any one has matched
312) successfully, no subsequent rules are considered.  You can specify that no
313) redirection is to be performed on a given set of addresses by using the
314) special target string &quot;pass&quot;, which prevents subsequent rules from being
315) considered.
316) <DT><B>ShutdownWaitLength</B><I>NUM</I><DD>
317) When we get a SIGINT and we're a server, we begin shutting down: we close
318) listeners and start refusing new circuits. After <B>NUM</B> seconds,
319) we exit. If we get a second SIGINT, we exit immediately.  (Default:
320) 30 seconds)
321) <DT><B>DirPostPeriod </B><I>N</I> <B>seconds</B>|<B>minutes</B>|<B>hours</B>|<B>days</B>|<B>weeks</B><DD>
322) Every time the specified period elapses, Tor uploads its server
323) descriptors to the directory servers.  This information is also
324) uploaded whenever it changes.  (Default: 20 minutes.)
325) <DT><B>AccountingMax </B><I>N</I> <B>bytes</B>|<B>KB</B>|<B>MB</B>|<B>GB</B>|<B>TB</B><DD>
326) Never send more than the specified number of bytes in a given
327) accounting period, or receive more than that number in the period.

328) For example, with AccountingMax set to 1 GB, a server could send 900 MB

330) of the two reaches 1 GB.

331) When the number of bytes is exhausted, Tor will hibernate until some
332) time in the next accounting period.  To prevent all servers from
333) waking at the same time, Tor will also wait until a random point in
334) each period before waking up.  If you have bandwidth cost issues,

336) provides users with a collection of fast servers that are up some of
337) the time, which is more useful than a set of slow servers that are
338) always &quot;available&quot;.
339) <DT><B>AccountingStart </B><B>day</B>|<B>week</B>|<B>month</B> [<I>day</I>] <I>HH:MM</I><DD>
340) Specify how long accounting periods last.  If <B>month</B> is given,
341) each accounting period runs from the time <I>HH:MM</I> on the
342) <I>day</I>th day of one month to the same day and time of the next.
343) (The day must be between 1 and 28.)  If <B>week</B> is given, each
344) accounting period runs from the time <I>HH:MM</I> of the <I>day</I>th
345) day of one week to the same day and time of the next week, with Monday
346) as day 1 and Sunday as day 7.  If <B>day</B> is given, each accounting
347) period runs from the time <I>HH:MM</I> each day to the same time on the
348) next day.  All times are local, and given in 24-hour time.  (Defaults to

353) <H2>DIRECTORY SERVER OPTIONS</H2>

355) <P>
356) 
357) The following options are useful only for directory servers (that is, if <B>DirPort</B> is non-zero):
358) <DL COMPACT>
359) <DT><B>AuthoritativeDirectory </B><B>0</B>|<B>1</B><DD>
360) When this option is set to 1, Tor operates as an authoritative
361) directory server.  Instead of caching the directory, it generates its
362) own list of good servers, signs it, and sends that to the clients.
363) Unless the clients already have you listed as a trusted directory, you
364) probably do not want to set this option.  Please coordinate with the other
365) admins at <A HREF="mailto:tor-ops@freehaven.net">tor-ops@freehaven.net</A> if you think you should be a directory.

371) <DT><B>DirPolicy </B><I>policy</I>,<I>policy</I>,<I>...</I><DD>
372) Set an entrance policy for this server, to limit who can connect to the directory ports. The policies have the same form as exit policies above.
373) <DT><B>RecommendedVersions </B><I>STRING</I><DD>
374) STRING is a command-separated list of Tor versions currently believed
375) to be safe. The list is included in each directory, and nodes which
376) pull down the directory learn whether they need to upgrade.  This
377) option can appear multiple times: the values from multiple lines are
378) spliced together.
379) <DT><B>DirAllowPrivateAddresses </B><B>0</B>|<B>1</B><DD>
380) If set to 1, Tor will accept router descriptors with arbitrary &quot;Address&quot;
381) elements. Otherwise, if the address is not an IP or is a private IP,
382) it will reject the router descriptor. Defaults to 0.
383) <DT><B>RunTesting </B><B>0</B>|<B>1</B><DD>
384) If set to 1, Tor tries to build circuits through all of the servers it
385) knows about, so it can tell which are up and which are down.  This
386) option is only useful for authoritative directories, so you probably
387) don't want to use it.

395) The following options are used to configure a hidden service.
396) <DL COMPACT>
397) <DT><B>HiddenServiceDir </B><I>DIRECTORY</I><DD>
398) Store data files for a hidden service in DIRECTORY.  Every hidden
399) service must have a separate directory.  You may use this option multiple
400) times to specify multiple services.
401) <DT><B>HiddenServicePort </B><I>VIRTPORT </I>[<I>TARGET</I>]<DD>
402) Configure a virtual port VIRTPORT for a hidden service.  You may use this
403) option multiple times; each time applies to the service using the most recent
404) hiddenservicedir.  By default, this option maps the virtual port to the
405) same port on 127.0.0.1.  You may override the target port, address, or both
406) by specifying a target of addr, port, or addr:port.
407) <DT><B>HiddenServiceNodes </B><I>nickname</I>,<I>nickname</I>,<I>...</I><DD>
408) If possible, use the specified nodes as introduction points for the hidden
409) service. If this is left unset, Tor will be smart and pick some reasonable
410) ones; most people can leave this unset.
411) <DT><B>HiddenServiceExcludeNodes </B><I>nickname</I>,<I>nickname</I>,<I>...</I><DD>
412) Do not use the specified nodes as introduction points for the hidden
413) service. In normal use there is no reason to set this.
