Renaming project to 'seth'
As discussed on tor-dev@ I'm scheming to rename this project from arm to
seth...
https://lists.torproject.org/pipermail/tor-dev/2015-March/008398.html
I'm taking this slow with the plan to wait another week before renaming the
repository, but I can move forward this much to get a feel of working with the
new name. We can revert later this week if we find a better name.

-accountingmax
-N bytes|KB|MB|GB|TB
-Never send more than the specified number of bytes in a given accounting period, or receive more than that number in the period. For example, with AccountingMax set to 1 GB, a server could send 900 MB and receive 800 MB and continue running. It will only hibernate once one of the two reaches 1 GB. When the number of bytes is exhausted, Tor will hibernate until some time in the next accounting period. To prevent all servers from waking at the same time, Tor will also wait until a random point in each period before waking up. If you have bandwidth cost issues, enabling hibernation is preferable to setting a low bandwidth, since it provides users with a collection of fast servers that are up some of the time, which is more useful than a set of slow servers that are always "available".

(The day must be between 1 and 28.) If week is given, each accounting period runs from the time HH:MM of the dayth day of one week to the same day and time of the next week, with Monday as day 1 and Sunday as day 7. If day is given, each accounting period runs from the time HH:MM each day to the same time on the next day. All times are local, and given in 24-hour time. (Defaults to "month 1 0:00".)

-If some Tor servers are obviously not working right, the directory authorities can manually mark them as invalid, meaning that it's not recommended you use them for entry or exit positions in your circuits. You can opt to use them in some circuit positions, though. The default is "middle,rendezvous", and other choices are not advised.

-authoritativedirectory
-0|1
-When this option is set to 1, Tor operates as an authoritative directory server. Instead of caching the directory, it generates its own list of good servers, signs it, and sends that to the clients. Unless the clients already have you listed as a trusted directory, you probably do not want to set this option. Please coordinate with the other admins at tor-ops at torproject.org if you think you should be a directory.

-When this option is enabled, and we get a request to resolve an address that ends with one of the suffixes in AutomapHostsSuffixes, we map an unused virtual address to that address, and return the new virtual address. This is handy for making ".onion" addresses work with applications that resolve an address and then connect to it. (Default: 0).

-IP:ORPort [fingerprint]
-When set along with UseBridges, instructs Tor to use the relay at "IP:ORPort" as a "bridge" relaying into the Tor network. If "fingerprint" is provided (using the same format as for DirServer), we will verify that the relay running at that location has the right fingerprint. We also use fingerprint to look up the bridge descriptor at the bridge authority, if it's provided and if UpdateBridgesFromAuthority is set too.
---------------------------------------------------------------------------------
-Directory
-index: 144
-bridgeauthoritativedir

-bridgerecordusagebycountry
-0|1
-When this option is enabled and BridgeRelay is also enabled, and we have GeoIP data, Tor keeps a keep a per-country count of how many client addresses have contacted it so that it can help the bridge authority guess which countries have blocked access to it. (Default: 1)

-circuitidletimeout
-NUM
-If we have kept a clean (never used) circuit around for NUM seconds, then close it. This way when the Tor client is entirely idle, it can expire all of its circuits, and then expire its TLS connections. Also, if we end up making a circuit that is not useful for exiting any of the requests we're receiving, it won't forever take up a slot in the circuit list. (Default: 1 hour.)
---------------------------------------------------------------------------------
-General
-index: 50
-circuitpriorityhalflife
-NUM1
-If this value is set, we override the default algorithm for choosing which circuit's cell to deliver or relay next. When the value is 0, we round-robin between the active circuits on a connection, delivering one cell from each in turn. When the value is positive, we prefer delivering cells from whichever connection has the lowest weighted cell count, where cells are weighted exponentially according to the supplied CircuitPriorityHalflife value (in seconds). If this option is not set at all, we use the behavior recommended in the current consensus networkstatus. This is an advanced option; you generally shouldn't have to mess with it. (Default: not set.)
---------------------------------------------------------------------------------
-Client
-index: 56
-circuitstreamtimeout
-NUM
-If non-zero, this option overrides our internal timeout schedule for how many seconds until we detach a stream from a circuit and try a new circuit. If your network is particularly slow, you might want to set this to a number like 60. (Default: 0)
---------------------------------------------------------------------------------
-Client
-index: 99
-clientdnsrejectinternaladdresses
-0|1
-If true, Tor does not believe any anonymously retrieved DNS answer that tells it that an address resolves to an internal address (like 127.0.0.1 or 192.168.0.1). This option prevents certain browser-based attacks; don't turn it off unless you know what you're doing. (Default: 1).
---------------------------------------------------------------------------------
-Client
-index: 57
-clientonly
-0|1
-If set to 1, Tor will under no circumstances run as a server or serve directory requests. The default is to run as a client unless ORPort is configured. (Usually, you don't need to set this; Tor is pretty smart at figuring out whether you are reliable and high-bandwidth enough to be a useful server.) (Default: 0)
---------------------------------------------------------------------------------

-STRING is a space-separated list of key=value pairs that Tor will include in the "params" line of its networkstatus vote.
---------------------------------------------------------------------------------
-General
-index: 7
-constrainedsockets
-0|1
-If set, Tor will tell the kernel to attempt to shrink the buffers for all sockets to the size specified in ConstrainedSockSize. This is useful for virtual servers and other environments where system level TCP buffers may be limited. If you're on a virtual server, and you encounter the "Error creating network socket: No buffer space available" message, you are likely experiencing this problem.
-
-The preferred solution is to have the admin increase the buffer pool for the host itself via /proc/sys/net/ipv4/tcp_mem or equivalent facility; this configuration option is a second-resort.
-
-The DirPort option should also not be used if TCP buffers are scarce. The cached directory requests consume additional sockets which exacerbates the problem.
-
-You should not enable this feature unless you encounter the "no buffer space available" issue. Reducing the TCP buffers affects window size for the TCP stream and will reduce throughput in proportion to round trip time on long paths. (Default: 0.)
---------------------------------------------------------------------------------
-General
-index: 8
-constrainedsocksize
-N bytes|KB
-When ConstrainedSockets is enabled the receive and transmit buffers for all sockets will be set to this limit. Must be a value between 2048 and 262144, in 1024 byte increments. Default of 8192 is recommended.

-General
-index: 10
-controllistenaddress
-IP[:PORT]
-Bind the controller listener to this address. If you specify a port, bind to this port rather than the one specified in ControlPort. We strongly recommend that you leave this alone unless you know what you're doing, since giving attackers access to your control listener is really dangerous. (Default: 127.0.0.1) This directive can be specified multiple times to bind to multiple addresses/ports.
---------------------------------------------------------------------------------
-General
-index: 9
-controlport
-Port
-If set, Tor will accept connections on this port and allow those connections to control the Tor process using the Tor Control Protocol (described in control-spec.txt). Note: unless you also specify one of HashedControlPassword or CookieAuthentication, setting this option will cause Tor to allow any process on the local host to control it. This option is required for many Tor controllers; most use the value of 9051.
---------------------------------------------------------------------------------
-General

-cookieauthentication
-0|1
-If this option is set to 1, don't allow any connections on the control port except when the connecting process knows the contents of a file named "control_auth_cookie", which Tor will create in its data directory. This authentication method should only be used on systems with good filesystem security. (Default: 0)

-dirlistenaddress
-IP[:PORT]
-Bind the directory service to this address. If you specify a port, bind to this port rather than the one specified in DirPort. (Default: 0.0.0.0) This directive can be specified multiple times to bind to multiple addresses/ports.

-General
-index: 17
-dirserver
-[nickname] [flags] address:port fingerprint
-Use a nonstandard authoritative directory server at the provided address and port, with the specified key fingerprint. This option can be repeated many times, for multiple authoritative directory servers. Flags are separated by spaces, and determine what kind of an authority this directory is. By default, every authority is authoritative for current ("v2")-style directories, unless the "no-v2" flag is given. If the "v1" flags is provided, Tor will use this server as an authority for old-style (v1) directories as well. (Only directory mirrors care about this.) Tor will use this server as an authority for hidden service information if the "hs" flag is set, or if the "v1" flag is set and the "no-hs" flag is not set. Tor will use this authority as a bridge authoritative directory if the "bridge" flag is set. If a flag "orport=port" is given, Tor will use the given port when opening encrypted tunnels to the dirserver. Lastly, if a flag "v3ident=fp" is given, the dirserver is a v3 directo
ry authority whose v3 long-term signing key has the fingerprint fp.
-
-If no dirserver line is given, Tor will use the default directory servers. NOTE: this option is intended for setting up a private Tor network with its own directory authorities. If you use it, you will be distinguishable from other users, because you won't believe the same authorities they do.
---------------------------------------------------------------------------------

-If set to 1, Tor will attempt to lock all current and future memory pages, so that memory cannot be paged out. Windows, OS X and Solaris are currently not supported. We believe that this feature works on modern Gnu/Linux distributions, and that it should work on *BSD systems (untested). This option requires that you start your Tor as root, and you should use the User option to properly reduce Tor's privileges. (Default: 0)

-exitpolicy
-policy,policy,...
-Set an exit policy for this server. Each policy is of the form "accept|reject ADDR[/MASK][:PORT]". If /MASK is omitted then this policy just applies to the host given. Instead of giving a host or network you can also use "*" to denote the universe (0.0.0.0/0). PORT can be a single port number, an interval of ports "FROM_PORT-TO_PORT", or "*". If PORT is omitted, that means "*".
-
-For example, "accept 18.7.22.69:*,reject 18.0.0.0/8:*,accept *:*" would reject any traffic destined for MIT except for web.mit.edu, and accept anything else.
-
-To specify all internal and link-local networks (including 0.0.0.0/8, 169.254.0.0/16, 127.0.0.0/8, 192.168.0.0/16, 10.0.0.0/8, and 172.16.0.0/12), you can use the "private" alias instead of an address. These addresses are rejected by default (at the beginning of your exit policy), along with your public IP address, unless you set the ExitPolicyRejectPrivate config option to 0. For example, once you've done that, you could allow HTTP to 127.0.0.1 and block all other connections to internal networks with "accept 127.0.0.1:80,reject private:*", though that may also allow connections to your own computer that are addressed to its public (external) IP address. See RFC 1918 and RFC 3330 for more details about internal and reserved IP address space.
-
-This directive can be specified multiple times so you don't have to put it all on one line.
-
-Policies are considered first to last, and the first match wins. If you want to _replace_ the default exit policy, end your exit policy with either a reject *:* or an accept *:*. Otherwise, you're _augmenting_ (prepending to) the default exit policy. The default exit policy is:
-
- reject *:25
- reject *:119

For example, 'ReachableAddresses 99.0.0.0/8, reject 18.0.0.0/8:80, accept *:80' means that your firewall allows connections to everything inside net 99, rejects port 80 connections to net 18, and accepts connections to port 80 otherwise.

This option, like all other ServerDNS options, only affects name lookups that your server does on behalf of clients. (Defaults to use the system DNS configuration.)
---------------------------------------------------------------------------------
-Relay
-index: 123
-serverdnssearchdomains
-0|1
-If set to 1, then we will search for addresses in the local search domain. For example, if this system is configured to believe it is in "example.com", and a client tries to connect to "www", the client will be connected to "www.example.com". This option only affects name lookups that your server does on behalf of clients. (Defaults to "0".)
---------------------------------------------------------------------------------
-Relay

-When we're detecting DNS hijacking, make sure that these valid addresses aren't getting redirected. If they are, then our DNS is completely useless, and we'll reset our exit policy to "reject :". This option only affects name lookups that your server does on behalf of clients. (Defaults to "www.google.com, www.mit.edu, www.yahoo.com, www.slashdot.org".)

-strictnodes
-0|1
-If 1 and EntryNodes config option is set, Tor will never use any nodes besides those listed in EntryNodes for the first hop of a normal circuit. If 1 and ExitNodes config option is set, Tor will never use any nodes besides those listed in ExitNodes for the last hop of a normal exit circuit. Note that Tor might still use these nodes for non-exit circuits such as one-hop directory fetches or hidden service support circuits.

---------------------------------------------------------------------------------
-Client
-index: 86
-testsocks
-0|1
-When this option is enabled, Tor will make a notice-level log entry for each connection to the Socks port indicating whether the request used a safe socks protocol or an unsafe one (see above entry on SafeSocks). This helps to determine whether an application using Tor is possibly leaking DNS requests. (Default: 0)
---------------------------------------------------------------------------------
-Client
-index: 79
-trackhostexits
-host,.domain,...
-For each value in the comma separated list, Tor will track recent connections to hosts that match this value and attempt to reuse the same exit node for each. If the value is prepended with a '.', it is treated as matching an entire domain. If one of the values is just a '.', it means match everything. This option is useful if you frequently connect to sites that will expire all your authentication cookies (i.e. log you out) if your IP address changes. Note that this option does have the disadvantage of making it more clear that a given history is associated with a single user. However, most people who would wish to observe this will observe it through cookies or other protocol-specific means anyhow.
---------------------------------------------------------------------------------
-Client
-index: 80
-trackhostexitsexpire
-NUM
-Since exit servers go up and down, it is desirable to expire the association between host and exit server after NUM seconds. The default is 1800 seconds (30 minutes).
---------------------------------------------------------------------------------
-Client
-index: 92
-translistenaddress
-IP[:PORT]
-Bind to this address to listen for transparent proxy connections. (Default: 127.0.0.1). This is useful for exporting a transparent proxy server to an entire network.
---------------------------------------------------------------------------------
-Client
-index: 91
-transport
-PORT
-If non-zero, enables transparent proxy support on PORT (by convention, 9040). Requires OS support for transparent proxies, such as BSDs' pf or Linux's IPTables. If you're planning to use Tor as a transparent proxy for a network, you'll want to examine and change VirtualAddrNetwork from the default setting. You'll also want to set the TransListenAddress option for the network you'd like to proxy. (Default: 0).
---------------------------------------------------------------------------------
-General
-index: 48
-tunneldirconns
-0|1
-If non-zero, when a directory server we contact supports it, we will build a one-hop circuit and make an encrypted connection via its ORPort. (Default: 1)
---------------------------------------------------------------------------------
-Client
-index: 81
-updatebridgesfromauthority
-0|1
-When set (along with UseBridges), Tor will try to fetch bridge descriptors from the configured bridge authorities when feasible. It will fall back to a direct request if the authority responds with a 404. (Default: 0)
---------------------------------------------------------------------------------
-Client
-index: 82
-usebridges
-0|1
-When set, Tor will fetch descriptors for each bridge listed in the "Bridge" config lines, and use these relays as both entry guards and directory guards. (Default: 0)
---------------------------------------------------------------------------------
-Client
-index: 83
-useentryguards
-0|1
-If this option is set to 1, we pick a few long-term entry servers, and try to stick with them. This is desirable because constantly changing servers increases the odds that an adversary who owns some servers will observe a fraction of your paths. (Defaults to 1.)
---------------------------------------------------------------------------------

-When this option is set in addition to AuthoritativeDirectory, Tor generates version 1 directory and running-routers documents (for legacy Tor clients up to 0.1.0.x).
---------------------------------------------------------------------------------
-Directory
-index: 138
-v2authoritativedirectory
-0|1
-When this option is set in addition to AuthoritativeDirectory, Tor generates version 2 network statuses and serves descriptors, etc as described in doc/spec/dir-spec-v2.txt (for Tor clients and servers running 0.1.1.x and 0.1.2.x).
---------------------------------------------------------------------------------
-Authority
-index: 165
-v3authdistdelay
-N minutes|hours
-V3 authoritative directories only. Configures the server's preferred delay between publishing its consensus and signature and assuming it has all the signatures from all the other authorities. Note that the actual time used is not the server's preferred time, but the consensus of all preferences. (Default: 5 minutes.)
---------------------------------------------------------------------------------
-Authority
-index: 166
-v3authnintervalsvalid
-NUM
-V3 authoritative directories only. Configures the number of VotingIntervals for which each consensus should be valid for. Choosing high numbers increases network partitioning risks; choosing low numbers increases directory traffic. Note that the actual number of intervals used is not the server's preferred number, but the consensus of all preferences. Must be at least 2. (Default: 3.)
---------------------------------------------------------------------------------
-Directory
-index: 139
-v3authoritativedirectory
-0|1
-When this option is set in addition to AuthoritativeDirectory, Tor generates version 3 network statuses and serves descriptors, etc as described in doc/spec/dir-spec.txt (for Tor clients and servers running at least 0.2.0.x).
---------------------------------------------------------------------------------
-Authority
-index: 164
-v3authvotedelay
-N minutes|hours
-V3 authoritative directories only. Configures the server's preferred delay between publishing its vote and assuming it has all the votes from all the other authorities. Note that the actual time used is not the server's preferred time, but the consensus of all preferences. (Default: 5 minutes.)
---------------------------------------------------------------------------------
-Authority
-index: 163
-v3authvotinginterval
-N minutes|hours
-V3 authoritative directories only. Configures the server's preferred voting interval. Note that voting will actually happen at an interval chosen by consensus from all the authorities' preferred intervals. This time SHOULD divide evenly into a day. (Default: 1 hour)
---------------------------------------------------------------------------------
-Directory
-index: 140
-versioningauthoritativedirectory
-0|1
-When this option is set to 1, Tor adds information on which versions of Tor are still believed safe for use to the published directory. Each version 1 authority is automatically a versioning authority; version 2 authorities provide this service optionally. See RecommendedVersions, RecommendedClientVersions, and RecommendedServerVersions.
---------------------------------------------------------------------------------
-Client
-index: 87
-virtualaddrnetwork
-Address/bits
-When a controller asks for a virtual (unused) address with the MAPADDRESS command, Tor picks an unassigned address from this range. (Default: 127.192.0.0/10)
-
-When providing proxy server service to a network of computers using a tool like dns-proxy-tor, change this address to "10.192.0.0/10" or "172.16.0.0/12". The default VirtualAddrNetwork address range on a properly configured machine will route to the loopback interface. For local use, no change to the default VirtualAddrNetwork setting is needed.
---------------------------------------------------------------------------------
-Client
-index: 102
-warnplaintextports
-port,port,...
-Tells Tor to issue a warnings whenever the user tries to make an anonymous connection to one of these ports. This option is designed to alert users to services that risk sending passwords in the clear. (Default: 23,109,110,143).

+providing real time statistics for:
+ * bandwidth, cpu, and memory usage
+ * relay's current configuration
+ * logged events
+ * connection details (ip, hostname, fingerprint, and consensus data)
+ * etc
+
+Defaults and interface properties are configurable via a user provided
+configuration file (for an example see the provided \fBsethrc.sample\fR).
+Releases and information are available at \fIhttp://www.atagar.com/seth\fR.
+

+accountingmax
+N bytes|KB|MB|GB|TB
+Never send more than the specified number of bytes in a given accounting period, or receive more than that number in the period. For example, with AccountingMax set to 1 GB, a server could send 900 MB and receive 800 MB and continue running. It will only hibernate once one of the two reaches 1 GB. When the number of bytes is exhausted, Tor will hibernate until some time in the next accounting period. To prevent all servers from waking at the same time, Tor will also wait until a random point in each period before waking up. If you have bandwidth cost issues, enabling hibernation is preferable to setting a low bandwidth, since it provides users with a collection of fast servers that are up some of the time, which is more useful than a set of slow servers that are always "available".
+--------------------------------------------------------------------------------
+Relay
+index: 120
+accountingstart

+Specify how long accounting periods last. If month is given, each accounting period runs from the time HH:MM on the dayth day of one month to the same day and time of the next. (The day must be between 1 and 28.) If week is given, each accounting period runs from the time HH:MM of the dayth day of one week to the same day and time of the next week, with Monday as day 1 and Sunday as day 7. If day is given, each accounting period runs from the time HH:MM each day to the same time on the next day. All times are local, and given in 24-hour time. (Defaults to "month 1 0:00".)

+allowdotexit
+0|1
+If enabled, we convert "www.google.com.foo.exit" addresses on the SocksPort/TransPort/NatdPort into "www.google.com" addresses that exit from the node "foo". Disabled by default since attacking websites and exit relays can use it to manipulate your path selection. (Default: 0)

+allowinvalidnodes
+entry|exit|middle|introduction|rendezvous|...
+If some Tor servers are obviously not working right, the directory authorities can manually mark them as invalid, meaning that it's not recommended you use them for entry or exit positions in your circuits. You can opt to use them in some circuit positions, though. The default is "middle,rendezvous", and other choices are not advised.
+--------------------------------------------------------------------------------
+Client
+index: 88
+allownonrfc953hostnames

+assumereachable
+0|1
+This option is used when bootstrapping a new Tor network. If set to 1, don't do self-reachability testing; just upload your server descriptor immediately. If AuthoritativeDirectory is also set, this option instructs the dirserver to bypass remote reachability testing too and list all connected servers as running.

+authdirlistbaddirs
+0|1
+Authoritative directories only. If set to 1, this directory has some opinion about which nodes are unsuitable as directory caches. (Do not set this to 1 unless you plan to list non-functioning directories as bad; otherwise, you are effectively voting in favor of every declared directory.)

+authdirrejectunlisted
+0|1
+Authoritative directories only. If set to 1, the directory server rejects all uploaded server descriptors that aren't explicitly listed in the fingerprints file. This acts as a "panic button" if we get hit with a Sybil attack. (Default: 0)
+--------------------------------------------------------------------------------
+Directory
+index: 135
+authoritativedirectory
+0|1
+When this option is set to 1, Tor operates as an authoritative directory server. Instead of caching the directory, it generates its own list of good servers, signs it, and sends that to the clients. Unless the clients already have you listed as a trusted directory, you probably do not want to set this option. Please coordinate with the other admins at tor-ops at torproject.org if you think you should be a directory.

+Client
+index: 95
+automaphostsonresolve
+0|1
+When this option is enabled, and we get a request to resolve an address that ends with one of the suffixes in AutomapHostsSuffixes, we map an unused virtual address to that address, and return the new virtual address. This is handy for making ".onion" addresses work with applications that resolve an address and then connect to it. (Default: 0).
+--------------------------------------------------------------------------------
+Client
+index: 96
+automaphostssuffixes

+Client
+index: 53
+bridge
+IP:ORPort [fingerprint]
+When set along with UseBridges, instructs Tor to use the relay at "IP:ORPort" as a "bridge" relaying into the Tor network. If "fingerprint" is provided (using the same format as for DirServer), we will verify that the relay running at that location has the right fingerprint. We also use fingerprint to look up the bridge descriptor at the bridge authority, if it's provided and if UpdateBridgesFromAuthority is set too.
+--------------------------------------------------------------------------------
+Directory
+index: 144
+bridgeauthoritativedir
+0|1
+When this option is set in addition to AuthoritativeDirectory, Tor accepts and serves router descriptors, but it caches and serves the main networkstatus documents rather than generating its own. (Default: 0)
+--------------------------------------------------------------------------------
+Relay
+index: 127
+bridgerecordusagebycountry
+0|1
+When this option is enabled and BridgeRelay is also enabled, and we have GeoIP data, Tor keeps a keep a per-country count of how many client addresses have contacted it so that it can help the bridge authority guess which countries have blocked access to it. (Default: 1)
+--------------------------------------------------------------------------------
+Relay
+index: 107
+bridgerelay
+0|1
+Sets the relay to act as a "bridge" with respect to relaying connections from bridge users to the Tor network. Mainly it influences how the relay will cache and serve directory information. Usually used in combination with PublishServerDescriptor.

+Relay
+index: 130
+cellstatistics

+Client
+index: 54
+circuitbuildtimeout

+--------------------------------------------------------------------------------
+Client
+index: 55
+circuitidletimeout
+NUM
+If we have kept a clean (never used) circuit around for NUM seconds, then close it. This way when the Tor client is entirely idle, it can expire all of its circuits, and then expire its TLS connections. Also, if we end up making a circuit that is not useful for exiting any of the requests we're receiving, it won't forever take up a slot in the circuit list. (Default: 1 hour.)
+--------------------------------------------------------------------------------
+General
+index: 50
+circuitpriorityhalflife
+NUM1
+If this value is set, we override the default algorithm for choosing which circuit's cell to deliver or relay next. When the value is 0, we round-robin between the active circuits on a connection, delivering one cell from each in turn. When the value is positive, we prefer delivering cells from whichever connection has the lowest weighted cell count, where cells are weighted exponentially according to the supplied CircuitPriorityHalflife value (in seconds). If this option is not set at all, we use the behavior recommended in the current consensus networkstatus. This is an advanced option; you generally shouldn't have to mess with it. (Default: not set.)
+--------------------------------------------------------------------------------
+Client
+index: 56
+circuitstreamtimeout
+NUM
+If non-zero, this option overrides our internal timeout schedule for how many seconds until we detach a stream from a circuit and try a new circuit. If your network is particularly slow, you might want to set this to a number like 60. (Default: 0)
+--------------------------------------------------------------------------------
+Client
+index: 99
+clientdnsrejectinternaladdresses
+0|1
+If true, Tor does not believe any anonymously retrieved DNS answer that tells it that an address resolves to an internal address (like 127.0.0.1 or 192.168.0.1). This option prevents certain browser-based attacks; don't turn it off unless you know what you're doing. (Default: 1).
+--------------------------------------------------------------------------------
+Client
+index: 57
+clientonly
+0|1
+If set to 1, Tor will under no circumstances run as a server or serve directory requests. The default is to run as a client unless ORPort is configured. (Usually, you don't need to set this; Tor is pretty smart at figuring out whether you are reliable and high-bandwidth enough to be a useful server.) (Default: 0)
+--------------------------------------------------------------------------------
+Authority
+index: 152
+consensusparams
+STRING
+STRING is a space-separated list of key=value pairs that Tor will include in the "params" line of its networkstatus vote.
+--------------------------------------------------------------------------------
+General
+index: 7
+constrainedsockets
+0|1
+If set, Tor will tell the kernel to attempt to shrink the buffers for all sockets to the size specified in ConstrainedSockSize. This is useful for virtual servers and other environments where system level TCP buffers may be limited. If you're on a virtual server, and you encounter the "Error creating network socket: No buffer space available" message, you are likely experiencing this problem.
+
+The preferred solution is to have the admin increase the buffer pool for the host itself via /proc/sys/net/ipv4/tcp_mem or equivalent facility; this configuration option is a second-resort.
+
+The DirPort option should also not be used if TCP buffers are scarce. The cached directory requests consume additional sockets which exacerbates the problem.
+
+You should not enable this feature unless you encounter the "no buffer space available" issue. Reducing the TCP buffers affects window size for the TCP stream and will reduce throughput in proportion to round trip time on long paths. (Default: 0.)
+--------------------------------------------------------------------------------
+General
+index: 8
+constrainedsocksize
+N bytes|KB
+When ConstrainedSockets is enabled the receive and transmit buffers for all sockets will be set to this limit. Must be a value between 2048 and 262144, in 1024 byte increments. Default of 8192 is recommended.
+--------------------------------------------------------------------------------
+Relay

+--------------------------------------------------------------------------------
+General
+index: 10
+controllistenaddress
+IP[:PORT]
+Bind the controller listener to this address. If you specify a port, bind to this port rather than the one specified in ControlPort. We strongly recommend that you leave this alone unless you know what you're doing, since giving attackers access to your control listener is really dangerous. (Default: 127.0.0.1) This directive can be specified multiple times to bind to multiple addresses/ports.
+--------------------------------------------------------------------------------
+General
+index: 9
+controlport
+Port
+If set, Tor will accept connections on this port and allow those connections to control the Tor process using the Tor Control Protocol (described in control-spec.txt). Note: unless you also specify one of HashedControlPassword or CookieAuthentication, setting this option will cause Tor to allow any process on the local host to control it. This option is required for many Tor controllers; most use the value of 9051.
+--------------------------------------------------------------------------------
+General
+index: 11
+controlsocket

+General
+index: 13
+cookieauthentication
+0|1
+If this option is set to 1, don't allow any connections on the control port except when the connecting process knows the contents of a file named "control_auth_cookie", which Tor will create in its data directory. This authentication method should only be used on systems with good filesystem security. (Default: 0)
+--------------------------------------------------------------------------------
+General
+index: 14
+cookieauthfile

+If this option is set to 0, don't allow the filesystem group to read the cookie file. If the option is set to 1, make the cookie file readable by the default GID. [Making the file readable by other groups is not yet implemented; let us know if you need this for some reason.] (Default: 0).

+Directory
+index: 147
+dirlistenaddress
+IP[:PORT]
+Bind the directory service to this address. If you specify a port, bind to this port rather than the one specified in DirPort. (Default: 0.0.0.0) This directive can be specified multiple times to bind to multiple addresses/ports.

+Use a nonstandard authoritative directory server at the provided address and port, with the specified key fingerprint. This option can be repeated many times, for multiple authoritative directory servers. Flags are separated by spaces, and determine what kind of an authority this directory is. By default, every authority is authoritative for current ("v2")-style directories, unless the "no-v2" flag is given. If the "v1" flags is provided, Tor will use this server as an authority for old-style (v1) directories as well. (Only directory mirrors care about this.) Tor will use this server as an authority for hidden service information if the "hs" flag is set, or if the "v1" flag is set and the "no-hs" flag is not set. Tor will use this authority as a bridge authoritative directory if the "bridge" flag is set. If a flag "orport=port" is given, Tor will use the given port when opening encrypted tunnels to the dirserver. Lastly, if a flag "v3ident=fp" is given, the dirserver is a v3 directo
ry authority whose v3 long-term signing key has the fingerprint fp.
+
+If no dirserver line is given, Tor will use the default directory servers. NOTE: this option is intended for setting up a private Tor network with its own directory authorities. If you use it, you will be distinguishable from other users, because you won't believe the same authorities they do.

+If set to 1, Tor will attempt to lock all current and future memory pages, so that memory cannot be paged out. Windows, OS X and Solaris are currently not supported. We believe that this feature works on modern Gnu/Linux distributions, and that it should work on *BSD systems (untested). This option requires that you start your Tor as root, and you should use the User option to properly reduce Tor's privileges. (Default: 0)

+index: 109
+exitpolicy
+policy,policy,...
+Set an exit policy for this server. Each policy is of the form "accept|reject ADDR[/MASK][:PORT]". If /MASK is omitted then this policy just applies to the host given. Instead of giving a host or network you can also use "*" to denote the universe (0.0.0.0/0). PORT can be a single port number, an interval of ports "FROM_PORT-TO_PORT", or "*". If PORT is omitted, that means "*".
+
+For example, "accept 18.7.22.69:*,reject 18.0.0.0/8:*,accept *:*" would reject any traffic destined for MIT except for web.mit.edu, and accept anything else.
+
+To specify all internal and link-local networks (including 0.0.0.0/8, 169.254.0.0/16, 127.0.0.0/8, 192.168.0.0/16, 10.0.0.0/8, and 172.16.0.0/12), you can use the "private" alias instead of an address. These addresses are rejected by default (at the beginning of your exit policy), along with your public IP address, unless you set the ExitPolicyRejectPrivate config option to 0. For example, once you've done that, you could allow HTTP to 127.0.0.1 and block all other connections to internal networks with "accept 127.0.0.1:80,reject private:*", though that may also allow connections to your own computer that are addressed to its public (external) IP address. See RFC 1918 and RFC 3330 for more details about internal and reserved IP address space.
+
+This directive can be specified multiple times so you don't have to put it all on one line.
+
+Policies are considered first to last, and the first match wins. If you want to _replace_ the default exit policy, end your exit policy with either a reject *:* or an accept *:*. Otherwise, you're _augmenting_ (prepending to) the default exit policy. The default exit policy is:
+
+ reject *:25
+ reject *:119
+ reject *:135-139
+ reject *:445
+ reject *:563
+ reject *:1214
+ reject *:4661-4666

+If 1, Tor will only create outgoing connections to ORs running on ports that your firewall allows (defaults to 80 and 443; see FirewallPorts). This will allow you to run Tor as a client behind a firewall with restrictive policies, but will not allow you to run as a server behind such a firewall. If you prefer more fine-grained control, use ReachableAddresses instead.

+When this option is disabled, Tor uses the public key step for the first hop of creating circuits. Skipping it is generally safe since we have already used TLS to authenticate the relay and to establish forward-secure keys. Turning this option off makes circuit building slower.
+
+Note that Tor will always use the public key step for the first hop if it's operating as a relay, and it will never use the public key step if it doesn't yet know the onion key of the first hop. (Default: 1)

The auth-type can either be 'basic' for a general-purpose authorization protocol or 'stealth' for a less scalable protocol that also hides service activity from unauthorized clients. Only clients that are listed here are authorized to access the hidden service. Valid client names are 1 to 19 characters long and only use characters in A-Za-z0-9+-_ (no spaces). If this option is set, the hidden service is not accessible for clients without authorization any more. Generated authorization data can be found in the hostname file.

+When this option is enabled, Tor will reject application connections that use unsafe variants of the socks protocol ones that only provide an IP address, meaning the application is doing a DNS resolve first. Specifically, these are socks4 and socks5 when not doing remote DNS. (Defaults to 0.)
+--------------------------------------------------------------------------------
+Relay
+index: 122
+serverdnsallowbrokenconfig
+0|1
+If this option is false, Tor exits immediately if there are problems parsing the system DNS configuration or connecting to nameservers. Otherwise, Tor continues to periodically retry the system nameservers until it eventually succeeds. (Defaults to "1".)
+--------------------------------------------------------------------------------
+Relay
+index: 126
+serverdnsallownonrfc953hostnames
+0|1
+When this option is disabled, Tor does not try to resolve hostnames containing illegal characters (like @ and :) rather than sending them to an exit node to be resolved. This helps trap accidental attempts to resolve URLs and so on. This option only affects name lookups that your server does on behalf of clients. (Default: 0)
+--------------------------------------------------------------------------------
+Relay
+index: 124
+serverdnsdetecthijacking
+0|1
+When this option is set to 1, we will test periodically to determine whether our local nameservers have been configured to hijack failing DNS requests (usually to an advertising site). If they are, we will attempt to correct this. This option only affects name lookups that your server does on behalf of clients. (Defaults to "1".)
+--------------------------------------------------------------------------------
+Relay
+index: 128
+serverdnsrandomizecase
+0|1
+When this option is set, Tor sets the case of each character randomly in outgoing DNS requests, and makes sure that the case matches in DNS replies. This so-called "0x20 hack" helps resist some types of DNS poisoning attack. For more information, see "Increased DNS Forgery Resistance through 0x20-Bit Encoding". This option only affects name lookups that your server does on behalf of clients. (Default: 1)
+--------------------------------------------------------------------------------
+Relay
+index: 121
+serverdnsresolvconffile
+filename
+Overrides the default DNS configuration with the configuration in filename. The file format is the same as the standard Unix "resolv.conf" file (7). This option, like all other ServerDNS options, only affects name lookups that your server does on behalf of clients. (Defaults to use the system DNS configuration.)
+--------------------------------------------------------------------------------
+Relay
+index: 123
+serverdnssearchdomains
+0|1
+If set to 1, then we will search for addresses in the local search domain. For example, if this system is configured to believe it is in "example.com", and a client tries to connect to "www", the client will be connected to "www.example.com". This option only affects name lookups that your server does on behalf of clients. (Defaults to "0".)
+--------------------------------------------------------------------------------
+Relay
+index: 125
+serverdnstestaddresses
+address,address,...
+When we're detecting DNS hijacking, make sure that these valid addresses aren't getting redirected. If they are, then our DNS is completely useless, and we'll reset our exit policy to "reject :". This option only affects name lookups that your server does on behalf of clients. (Defaults to "www.google.com, www.mit.edu, www.yahoo.com, www.slashdot.org".)

+Client
+index: 86
+testsocks
+0|1
+When this option is enabled, Tor will make a notice-level log entry for each connection to the Socks port indicating whether the request used a safe socks protocol or an unsafe one (see above entry on SafeSocks). This helps to determine whether an application using Tor is possibly leaking DNS requests. (Default: 0)
+--------------------------------------------------------------------------------
+Client
+index: 79
+trackhostexits
+host,.domain,...
+For each value in the comma separated list, Tor will track recent connections to hosts that match this value and attempt to reuse the same exit node for each. If the value is prepended with a '.', it is treated as matching an entire domain. If one of the values is just a '.', it means match everything. This option is useful if you frequently connect to sites that will expire all your authentication cookies (i.e. log you out) if your IP address changes. Note that this option does have the disadvantage of making it more clear that a given history is associated with a single user. However, most people who would wish to observe this will observe it through cookies or other protocol-specific means anyhow.
+--------------------------------------------------------------------------------
+Client
+index: 80
+trackhostexitsexpire
+NUM
+Since exit servers go up and down, it is desirable to expire the association between host and exit server after NUM seconds. The default is 1800 seconds (30 minutes).
+--------------------------------------------------------------------------------
+Client
+index: 92
+translistenaddress
+IP[:PORT]
+Bind to this address to listen for transparent proxy connections. (Default: 127.0.0.1). This is useful for exporting a transparent proxy server to an entire network.
+--------------------------------------------------------------------------------
+Client
+index: 91
+transport
+PORT
+If non-zero, enables transparent proxy support on PORT (by convention, 9040). Requires OS support for transparent proxies, such as BSDs' pf or Linux's IPTables. If you're planning to use Tor as a transparent proxy for a network, you'll want to examine and change VirtualAddrNetwork from the default setting. You'll also want to set the TransListenAddress option for the network you'd like to proxy. (Default: 0).
+--------------------------------------------------------------------------------
+General
+index: 48
+tunneldirconns

+Client
+index: 81
+updatebridgesfromauthority
+0|1
+When set (along with UseBridges), Tor will try to fetch bridge descriptors from the configured bridge authorities when feasible. It will fall back to a direct request if the authority responds with a 404. (Default: 0)
+--------------------------------------------------------------------------------
+Client
+index: 82
+usebridges
+0|1
+When set, Tor will fetch descriptors for each bridge listed in the "Bridge" config lines, and use these relays as both entry guards and directory guards. (Default: 0)
+--------------------------------------------------------------------------------
+Client
+index: 83
+useentryguards
+0|1
+If this option is set to 1, we pick a few long-term entry servers, and try to stick with them. This is desirable because constantly changing servers increases the odds that an adversary who owns some servers will observe a fraction of your paths. (Defaults to 1.)

+--------------------------------------------------------------------------------
+Directory
+index: 138
+v2authoritativedirectory

+V3 authoritative directories only. Configures the server's preferred delay between publishing its consensus and signature and assuming it has all the signatures from all the other authorities. Note that the actual time used is not the server's preferred time, but the consensus of all preferences. (Default: 5 minutes.)
+--------------------------------------------------------------------------------
+Authority
+index: 166
+v3authnintervalsvalid
+NUM
+V3 authoritative directories only. Configures the number of VotingIntervals for which each consensus should be valid for. Choosing high numbers increases network partitioning risks; choosing low numbers increases directory traffic. Note that the actual number of intervals used is not the server's preferred number, but the consensus of all preferences. Must be at least 2. (Default: 3.)
+--------------------------------------------------------------------------------
+Directory
+index: 139

+Authority
+index: 163
+v3authvotinginterval
+N minutes|hours
+V3 authoritative directories only. Configures the server's preferred voting interval. Note that voting will actually happen at an interval chosen by consensus from all the authorities' preferred intervals. This time SHOULD divide evenly into a day. (Default: 1 hour)
+--------------------------------------------------------------------------------
+Directory
+index: 140
+versioningauthoritativedirectory
+0|1
+When this option is set to 1, Tor adds information on which versions of Tor are still believed safe for use to the published directory. Each version 1 authority is automatically a versioning authority; version 2 authorities provide this service optionally. See RecommendedVersions, RecommendedClientVersions, and RecommendedServerVersions.
+--------------------------------------------------------------------------------
+Client
+index: 87
+virtualaddrnetwork
+Address/bits
+When a controller asks for a virtual (unused) address with the MAPADDRESS command, Tor picks an unassigned address from this range. (Default: 127.192.0.0/10)
+
+When providing proxy server service to a network of computers using a tool like dns-proxy-tor, change this address to "10.192.0.0/10" or "172.16.0.0/12". The default VirtualAddrNetwork address range on a properly configured machine will route to the loopback interface. For local use, no change to the default VirtualAddrNetwork setting is needed.
+--------------------------------------------------------------------------------
+Client
+index: 102
+warnplaintextports
+port,port,...
+Tells Tor to issue a warnings whenever the user tries to make an anonymous connection to one of these ports. This option is designed to alert users to services that risk sending passwords in the clear. (Default: 23,109,110,143).
