Overview - - The SOCKS protocol provides a generic interface for TCP proxies. Client - software connects to a SOCKS server via TCP, and requests a TCP connection - to another address and port. The SOCKS server establishes the connection, - and reports success or failure to the client. After the connection has - been established, the client application uses the TCP stream as usual. - - Tor supports SOCKS4 as defined in [1], SOCKS4A as defined in [2], and - SOCKS5 as defined in [3]. - - The stickiest issue for Tor in supporting clients, in practice, is forcing - DNS lookups to occur at the OR side: if clients do their own DNS lookup, - the DNS server can learn which addresses the client wants to reach. - SOCKS4 supports addressing by IPv4 address; SOCKS4A is a kludge on top of - SOCKS4 to allow addressing by hostname; SOCKS5 supports IPv4, IPv6, and - hostnames. - -1.1. Extent of support - - Tor supports the SOCKS4, SOCKS4A, and SOCKS5 standards, except as follows: - - BOTH: - - The BIND command is not supported. - - SOCKS4,4A: - - SOCKS4 usernames are ignored. - - SOCKS5: - - The (SOCKS5) "UDP ASSOCIATE" command is not supported. - - IPv6 is not supported in CONNECT commands. - - Only the "NO AUTHENTICATION" (SOCKS5) authentication method [00] is - supported. - -2. Name lookup - - As an extension to SOCKS4A and SOCKS5, Tor implements a new command value, - "RESOLVE" [F0]. When Tor receives a "RESOLVE" SOCKS command, it initiates - a remote lookup of the hostname provided as the target address in the SOCKS - request. The reply is either an error (if the address couldn't be - resolved) or a success response. In the case of success, the address is - stored in the portion of the SOCKS response reserved for remote IP address. - - (We support RESOLVE in SOCKS4 too, even though it is unnecessary.) - - For SOCKS5 only, we support reverse resolution with a new command value, - "RESOLVE_PTR" [F1]. In response to a "RESOLVE_PTR" SOCKS5 command with - an IPv4 address as its target, Tor attempts to find the canonical - hostname for that IPv4 record, and returns it in the "server bound - address" portion of the reply. - (This command was not supported before Tor 0.1.2.2-alpha.) - -3. Other command extensions. - - Tor 0.1.2.4-alpha added a new command value: "CONNECT_DIR" [F2]. - In this case, Tor will open an encrypted direct TCP connection to the - directory port of the Tor server specified by address:port (the port - specified should be the ORPort of the server). It uses a one-hop tunnel - and a "BEGIN_DIR" relay cell to accomplish this secure connection. - - The F2 command value was removed in Tor 0.2.0.10-alpha in favor of a - new use_begindir flag in edge_connection_t. - -4. HTTP-resistance - - Tor checks the first byte of each SOCKS request to see whether it looks - more like an HTTP request (that is, it starts with a "G", "H", or "P"). If - so, Tor returns a small webpage, telling the user that his/her browser is - misconfigured. This is helpful for the many users who mistakenly try to - use Tor as an HTTP proxy instead of a SOCKS proxy. - -References: - [1] http://archive.socks.permeo.com/protocol/socks4.protocol - [2] http://archive.socks.permeo.com/protocol/socks4a.protocol - [3] SOCKS5: RFC1928 - diff --git a/doc/socks/SOCKS4.protocol b/doc/socks/SOCKS4.protocol new file mode 100644 index 0000000..50fa5a7 --- /dev/null +++ b/doc/socks/SOCKS4.protocol @@ -0,0 +1,150 @@ + SOCKS: A protocol for TCP proxy across firewalls + + Ying-Da Lee + yingda(a)best.com or yingda(a)esd.sgi.com + +SOCKS was originally developed by David Koblas and subsequently modified +and extended by me to its current running version -- version 4.

Overview + + The SOCKS protocol provides a generic interface for TCP proxies. Client + software connects to a SOCKS server via TCP, and requests a TCP connection + to another address and port. The SOCKS server establishes the connection, + and reports success or failure to the client. After the connection has + been established, the client application uses the TCP stream as usual. + + Tor supports SOCKS4 as defined in [1], SOCKS4A as defined in [2], and + SOCKS5 as defined in [3]. + + The stickiest issue for Tor in supporting clients, in practice, is forcing + DNS lookups to occur at the OR side: if clients do their own DNS lookup, + the DNS server can learn which addresses the client wants to reach. + SOCKS4 supports addressing by IPv4 address; SOCKS4A is a kludge on top of + SOCKS4 to allow addressing by hostname; SOCKS5 supports IPv4, IPv6, and + hostnames. + +1.1. Extent of support + + Tor supports the SOCKS4, SOCKS4A, and SOCKS5 standards, except as follows: + + BOTH: + - The BIND command is not supported. + + SOCKS4,4A: + - SOCKS4 usernames are ignored. + + SOCKS5: + - The (SOCKS5) "UDP ASSOCIATE" command is not supported. + - IPv6 is not supported in CONNECT commands. + - Only the "NO AUTHENTICATION" (SOCKS5) authentication method [00] is + supported. + +2. Name lookup + + As an extension to SOCKS4A and SOCKS5, Tor implements a new command value, + "RESOLVE" [F0]. When Tor receives a "RESOLVE" SOCKS command, it initiates + a remote lookup of the hostname provided as the target address in the SOCKS + request. The reply is either an error (if the address couldn't be + resolved) or a success response. In the case of success, the address is + stored in the portion of the SOCKS response reserved for remote IP address. + + (We support RESOLVE in SOCKS4 too, even though it is unnecessary.) + + For SOCKS5 only, we support reverse resolution with a new command value, + "RESOLVE_PTR" [F1]. In response to a "RESOLVE_PTR" SOCKS5 command with + an IPv4 address as its target, Tor attempts to find the canonical + hostname for that IPv4 record, and returns it in the "server bound + address" portion of the reply. + (This command was not supported before Tor 0.1.2.2-alpha.) + +3. Other command extensions. + + Tor 0.1.2.4-alpha added a new command value: "CONNECT_DIR" [F2]. + In this case, Tor will open an encrypted direct TCP connection to the + directory port of the Tor server specified by address:port (the port + specified should be the ORPort of the server). It uses a one-hop tunnel + and a "BEGIN_DIR" relay cell to accomplish this secure connection. + + The F2 command value was removed in Tor 0.2.0.10-alpha in favor of a + new use_begindir flag in edge_connection_t. + +4. HTTP-resistance + + Tor checks the first byte of each SOCKS request to see whether it looks + more like an HTTP request (that is, it starts with a "G", "H", or "P"). If + so, Tor returns a small webpage, telling the user that his/her browser is + misconfigured. This is helpful for the many users who mistakenly try to + use Tor as an HTTP proxy instead of a SOCKS proxy. + +References: + [1] http://archive.socks.permeo.com/protocol/socks4.protocol + [2] http://archive.socks.permeo.com/protocol/socks4a.protocol + [3] SOCKS5: RFC1928 + diff --git a/doc/torsocks.1.in b/doc/torsocks.1.in new file mode 100644 index 0000000..b383859 --- /dev/null +++ b/doc/torsocks.1.in @@ -0,0 +1,63 @@ +.TH TORSOCKS 1 "" "TORSOCKS" + +.SH NAME +.BR torsocks +\- Shell wrapper to simplify the use of the torsocks(8) library to +transparently allow an application to use a SOCKS proxy.

For more +information on this configuration see the CAVEATS section of this +manual page. + +.SH DESCRIPTION + +.BR torsocks +is a library to allow transparent SOCKS proxying. It wraps the normal +connect() function. When a connection is attempted, it consults the +configuration file (which is defined at configure time but defaults to +/etc/torsocks.conf) and determines if the IP address specified is local. If +it is not, the library redirects the connection to a SOCKS server +specified in the configuration file. It then negotiates that connection +with the SOCKS server and passes the connection back to the calling +program. + +.BR torsocks +is designed for use in machines which are firewalled from then +internet. It avoids the need to recompile applications like lynx or +telnet so they can use SOCKS to reach the internet. It behaves much like +the SOCKSified TCP/IP stacks seen on other platforms. + +.SS ARGUMENTS +Most arguments to +.BR torsocks +are provided in the configuration file (the location of which is defined +at configure time by the \-\-with\-conf=<file> argument but defaults to +/etc/torsocks.conf). The structure of this file is documented in torsocks.conf(8) + +Some configuration options can be specified at run time using environment +variables as follows: + +.TP +.I TORSOCKS_CONFFILE +This environment variable overrides the default location of the torsocks +configuration file. This variable is not honored if the program torsocks +is embedded in is setuid. In addition this environment variable can +be compiled out of torsocks with the \-\-disable\-envconf argument to +configure at build time + +.TP +.I TORSOCKS_DEBUG +This environment variable sets the level of debug output that should be +generated by torsocks (debug output is generated in the form of output to +standard error). If this variable is not present by default the logging +level is set to 0 which indicates that only error messages should be output. +Setting it to higher values will cause torsocks to generate more messages +describing what it is doing. If set to \-1 torsocks will output absolutely no +error or debugging messages. This is only needed if torsocks output interferes +with a program it is embedded in. Message output can be permanently compiled +out of torsocks by specifying the \-\-disable\-debug option to configure at +build time + +.TP +.I TORSOCKS_DEBUG_FILE +This option can be used to redirect the torsocks output (which would normally +be sent to standard error) to a file. This variable is not honored if the +program torsocks is embedded in is setuid. For programs where torsocks output +interferes with normal operation this option is generally better than +disabling messages (with TORSOCKS_DEBUG = \-1) + +.TP +.I TORSOCKS_USERNAME +This environment variable can be used to specify the username to be used when +version 5 SOCKS servers request username/password authentication. This +overrides the default username that can be specified in the configuration +file using 'default_user', see torsocks.conf(8) for more information. This +variable is ignored for version 4 SOCKS servers. + +.TP +.I TORSOCKS_PASSWORD +This environment variable can be used to specify the password to be used when +version 5 SOCKS servers request username/password authentication. This +overrides the default password that can be specified in the configuration +file using 'default_pass', see torsocks.conf(8) for more information. This +variable is ignored for version 4 SOCKS servers. + +.SS DNS ISSUES +.BR torsocks +will normally not be able to send DNS queries through a SOCKS server since +SOCKS V4 works on TCP and DNS normally uses UDP. Version 1.5 and up do +however provide a method to force DNS lookups to use TCP, which then makes +them proxyable. This option can only enabled at compile time, please +consult the INSTALL file for more information. + +.SS ERRORS +.BR torsocks +will generate error messages and print them to stderr when there are +problems with the configuration file or the SOCKS negotiation with the +server if the TORSOCKS_DEBUG environment variable is not set to \-1 or and +\-\-disable\-debug was not specified at compile time. This output may cause +some problems with programs that redirect standard error. + +.SS CAVEATS +.BR torsocks +will not in the above configuration be able to provide SOCKS proxying to +setuid applications or applications that are not run from a shell. You can +force all applications to LD_PRELOAD the library by placing the path to +libtorsocks in /etc/ld.so.preload. Please make sure you correctly enter the +full path to the library in this file if you do this. If you get it wrong, +you will be UNABLE TO DO ANYTHING with the machine and will have to boot +it with a rescue disk and remove the file (or try the saveme program, see +the INSTALL file for more info). THIS IS A ***WARNING***, please be +careful. Also be sure the library is in the root filesystem as all hell +will break loose if the directory it is in is not available at boot time. + +.SH BUGS + +.BR torsocks +can only proxy outgoing TCP connections + +.BR torsocks +does NOT work correctly with asynchronous sockets (though it does work with +non blocking sockets). This bug would be very difficult to fix and there +appears to be no demand for it (I know of no major application that uses +asynchronous sockets) + +.BR torsocks +is NOT fully RFC compliant in its implementation of version 5 of SOCKS, it +only supports the 'username and password' or 'no authentication' +authentication methods. The RFC specifies GSSAPI must be supported by any +compliant implementation. I haven't done this, anyone want to help? + +.BR torsocks +can force the libc resolver to use TCP for name queries, if it does this +it does it regardless of whether or not the DNS to be queried is local or +not. This introduces overhead and should only be used when needed. + +.BR torsocks +uses ELF dynamic loader features to intercept dynamic function calls from +programs in which it is embedded. As a result, it cannot trace the +actions of statically linked executables, non-ELF executables, or +executables that make system calls directly with the system call trap or +through the syscall() routine. + +.SH FILES +@CONFDIR@/torsocks.conf - default torsocks configuration file + +.SH SEE ALSO +torsocks.conf(5) +torsocks(1) +usewithtor(1) + +.SH AUTHOR +Shaun Clowes (delius(a)progsoc.uts.edu.au) + +.SH COPYRIGHT +Copyright 2000 Shaun Clowes + +Renamed for use by torsocks to avoid conflict with tsocks by Robert Hogan. + +torsocks and its documentation may be freely copied under the terms and +conditions of version 2 of the GNU General Public License, as published +by the Free Software Foundation (Cambridge, Massachusetts, United +States of America). + +This documentation is based on the documentation for logwrites, another +shared library interceptor.

The basic idea is to define +any networks the machine can access directly (i.e without the use of a +SOCKS server) and define one or many SOCKS servers to be used to access +other networks (including a 'default' server). + +Local networks are declared using the 'local' keyword in the configuration +file. When applications attempt to connect to machines in networks marked +as local torsocks will not attempt to use a SOCKS server to negotiate the +connection. + +Obviously if a connection is not to a locally accessible network it will need +to be proxied over a SOCKS server. However, many installations have several +different SOCKS servers to be used to access different internal (and external) +networks. For this reason the configuration file allows the definition of +`paths' as well as a default SOCKS server. + +Paths are declared as blocks in the configuration file. That is, they begin +with a 'path {' line in the configuration file and end with a '}' line. Inside +this block directives should be used to declare a SOCKS server (as documented +later in this manual page) and 'reaches' directives should be used to declare +networks and even destination ports in those networks that this server should +be used to reach. N.B Each path MUST define a SOCKS server and contain one or +more 'reaches' directives. + +SOCKS server declaration directives that are not contained within a 'path' +block define the default SOCKS server. If torsocks needs to connect to a machine +via a SOCKS server (i.e it isn't a network declared as 'local') and no 'path' +has declared it can reach that network via a 'reaches' directive this server +is used to negotiate the connection. + +.SH CONFIGURATION SYNTAX + +The basic structure of all lines in the configuration file is: + +.RS +<directive> = <parameters> +.RE + +The exception to this is 'path' blocks which look like: + +.RS +path { +.RS +<directive> = <parameters> +.RE +} +.RE + +Empty lines are ignored and all input on a line after a '#' character is +ignored. + +.SS DIRECTIVES +The following directives are used in the torsocks configuration file: + +.TP +.I server +The IP address of the SOCKS server (e.g "server = 10.1.4.253"). Only one +server may be specified per path block, or one outside a path +block (to define the default server). Unless \-\-disable-hostnames was +specified to configure at compile time the server can be specified as +a hostname (e.g "server = socks.nec.com") + +.TP +.I server_port +The port on which the SOCKS server receives requests. Only one server_port +may be specified per path block, or one outside a path (for the default +server). This directive is not required if the server is on the +standard port (1080). + +.TP +.I server_type +SOCKS version used by the server. Versions 4 and 5 are supported (but both +for only the connect operation). The default is 4. Only one server_type +may be specified per path block, or one outside a path (for the default +server). + +You can use the inspectorsocks utility to determine the type of server, see +the 'UTILITIES' section later in this manual page. + +.TP +.I default_user +This specifies the default username to be used for username and password +authentication in SOCKS version 5. In order to determine the username to +use (if the socks server requires username and password authentication) +torsocks first looks for the environment variable TSOCKS_USERNAME, then +looks for this configuration option, then tries to get the local username. +This option is not valid for SOCKS version 4 servers. Only one default_user +may be specified per path block, or one outside a path (for the default +server) + +.TP +.I default_pass +This specified the default password to be used for username and password +authentication in SOCKS version 5. In order to determine the password to +use (if the socks server requires username and password authentication) +torsocks first looks for the environment variable TSOCKS_PASSWORD, then +looks for this configuration option. This option is not valid for SOCKS +version 4 servers. Onle one default_pass may be specified per path block, +or one outside a path (for the default server) + +.TP +.I local +An IP/Subnet pair specifying a network which may be accessed directly without +proxying through a SOCKS server (e.g "local = 10.0.0.0/255.0.0.0"). +Obviously all SOCKS server IP addresses must be in networks specified as +local, otherwise torsocks would need a SOCKS server to reach SOCKS servers. + +.TP +.I reaches +This directive is only valid inside a path block. Its parameter is formed +as IP[:startport[\-endport]]/Subnet and it specifies a network (and a range +of ports on that network) that can be accessed by the SOCKS server specified +in this path block. For example, in a path block "reaches = +150.0.0.0:80-1024/255.0.0.0" indicates to torsocks that the SOCKS server +specified in the current path block should be used to access any IPs in the +range 150.0.0.0 to 150.255.255.255 when the connection request is for ports +80-1024. + +.TP +.I tordns_enable +This enables the use of the 'tordns' feature in torsocks, which overrides the +standard C library name resolution calls to use SOCKS. The default value is +`true'. + +.TP +.I tordns_deadpool_range +Tor hidden sites do not have real IP addresses. This specifies what range of +IP addresses will be handed to the application as "cookies" for .onion names. +Of course, you should pick a block of addresses which you aren't going to ever +need to actually connect to. The default value is '127.0.69.0/255.255.255.0'. + +.TP +.I tordns_cache_size +This specifies the number of IP addresses looked up through SOCKS to cache. +The default value is 256. Each entry consumes 260 bytes of memory, so the +default adds 66,560 bytes of overhead to each 'torified' process. NOTE: if +the number of IP addresses in tordns_deadpool_range is less than the value +specified for tordns_cache_size, then the cache will be shrunk to fit the +deadpool range.

For more -information on this configuration see the CAVEATS section of this -manual page. - -.SH DESCRIPTION - -.BR torsocks -is a library to allow transparent SOCKS proxying. It wraps the normal -connect() function. When a connection is attempted, it consults the -configuration file (which is defined at configure time but defaults to -/etc/torsocks.conf) and determines if the IP address specified is local. If -it is not, the library redirects the connection to a SOCKS server -specified in the configuration file. It then negotiates that connection -with the SOCKS server and passes the connection back to the calling -program. - -.BR torsocks -is designed for use in machines which are firewalled from then -internet. It avoids the need to recompile applications like lynx or -telnet so they can use SOCKS to reach the internet. It behaves much like -the SOCKSified TCP/IP stacks seen on other platforms. - -.SS ARGUMENTS -Most arguments to -.BR torsocks -are provided in the configuration file (the location of which is defined -at configure time by the \-\-with\-conf=<file> argument but defaults to -/etc/torsocks.conf). The structure of this file is documented in torsocks.conf(8) - -Some configuration options can be specified at run time using environment -variables as follows: - -.TP -.I TORSOCKS_CONFFILE -This environment variable overrides the default location of the torsocks -configuration file. This variable is not honored if the program torsocks -is embedded in is setuid. In addition this environment variable can -be compiled out of torsocks with the \-\-disable\-envconf argument to -configure at build time - -.TP -.I TORSOCKS_DEBUG -This environment variable sets the level of debug output that should be -generated by torsocks (debug output is generated in the form of output to -standard error). If this variable is not present by default the logging -level is set to 0 which indicates that only error messages should be output. -Setting it to higher values will cause torsocks to generate more messages -describing what it is doing. If set to \-1 torsocks will output absolutely no -error or debugging messages. This is only needed if torsocks output interferes -with a program it is embedded in. Message output can be permanently compiled -out of torsocks by specifying the \-\-disable\-debug option to configure at -build time - -.TP -.I TORSOCKS_DEBUG_FILE -This option can be used to redirect the torsocks output (which would normally -be sent to standard error) to a file. This variable is not honored if the -program torsocks is embedded in is setuid. For programs where torsocks output -interferes with normal operation this option is generally better than -disabling messages (with TORSOCKS_DEBUG = \-1) - -.TP -.I TORSOCKS_USERNAME -This environment variable can be used to specify the username to be used when -version 5 SOCKS servers request username/password authentication. This -overrides the default username that can be specified in the configuration -file using 'default_user', see torsocks.conf(8) for more information. This -variable is ignored for version 4 SOCKS servers. - -.TP -.I TORSOCKS_PASSWORD -This environment variable can be used to specify the password to be used when -version 5 SOCKS servers request username/password authentication. This -overrides the default password that can be specified in the configuration -file using 'default_pass', see torsocks.conf(8) for more information. This -variable is ignored for version 4 SOCKS servers. - -.SS DNS ISSUES -.BR torsocks -will normally not be able to send DNS queries through a SOCKS server since -SOCKS V4 works on TCP and DNS normally uses UDP. Version 1.5 and up do -however provide a method to force DNS lookups to use TCP, which then makes -them proxyable. This option can only enabled at compile time, please -consult the INSTALL file for more information. - -.SS ERRORS -.BR torsocks -will generate error messages and print them to stderr when there are -problems with the configuration file or the SOCKS negotiation with the -server if the TORSOCKS_DEBUG environment variable is not set to \-1 or and -\-\-disable\-debug was not specified at compile time. This output may cause -some problems with programs that redirect standard error. - -.SS CAVEATS -.BR torsocks -will not in the above configuration be able to provide SOCKS proxying to -setuid applications or applications that are not run from a shell. You can -force all applications to LD_PRELOAD the library by placing the path to -libtorsocks in /etc/ld.so.preload. Please make sure you correctly enter the -full path to the library in this file if you do this. If you get it wrong, -you will be UNABLE TO DO ANYTHING with the machine and will have to boot -it with a rescue disk and remove the file (or try the saveme program, see -the INSTALL file for more info). THIS IS A ***WARNING***, please be -careful. Also be sure the library is in the root filesystem as all hell -will break loose if the directory it is in is not available at boot time. - -.SH BUGS - -.BR torsocks -can only proxy outgoing TCP connections - -.BR torsocks -does NOT work correctly with asynchronous sockets (though it does work with -non blocking sockets). This bug would be very difficult to fix and there -appears to be no demand for it (I know of no major application that uses -asynchronous sockets) - -.BR torsocks -is NOT fully RFC compliant in its implementation of version 5 of SOCKS, it -only supports the 'username and password' or 'no authentication' -authentication methods. The RFC specifies GSSAPI must be supported by any -compliant implementation. I haven't done this, anyone want to help? - -.BR torsocks -can force the libc resolver to use TCP for name queries, if it does this -it does it regardless of whether or not the DNS to be queried is local or -not. This introduces overhead and should only be used when needed. - -.BR torsocks -uses ELF dynamic loader features to intercept dynamic function calls from -programs in which it is embedded. As a result, it cannot trace the -actions of statically linked executables, non-ELF executables, or -executables that make system calls directly with the system call trap or -through the syscall() routine. - -.SH FILES -@CONFDIR@/torsocks.conf - default torsocks configuration file - -.SH SEE ALSO -torsocks.conf(5) -torsocks(1) -usewithtor(1) - -.SH AUTHOR -Shaun Clowes (delius(a)progsoc.uts.edu.au) - -.SH COPYRIGHT -Copyright 2000 Shaun Clowes - -Renamed for use by torsocks to avoid conflict with tsocks by Robert Hogan. - -torsocks and its documentation may be freely copied under the terms and -conditions of version 2 of the GNU General Public License, as published -by the Free Software Foundation (Cambridge, Massachusetts, United -States of America). - -This documentation is based on the documentation for logwrites, another -shared library interceptor.

The basic idea is to define -any networks the machine can access directly (i.e without the use of a -SOCKS server) and define one or many SOCKS servers to be used to access -other networks (including a 'default' server). - -Local networks are declared using the 'local' keyword in the configuration -file. When applications attempt to connect to machines in networks marked -as local torsocks will not attempt to use a SOCKS server to negotiate the -connection. - -Obviously if a connection is not to a locally accessible network it will need -to be proxied over a SOCKS server. However, many installations have several -different SOCKS servers to be used to access different internal (and external) -networks. For this reason the configuration file allows the definition of -`paths' as well as a default SOCKS server. - -Paths are declared as blocks in the configuration file. That is, they begin -with a 'path {' line in the configuration file and end with a '}' line. Inside -this block directives should be used to declare a SOCKS server (as documented -later in this manual page) and 'reaches' directives should be used to declare -networks and even destination ports in those networks that this server should -be used to reach. N.B Each path MUST define a SOCKS server and contain one or -more 'reaches' directives. - -SOCKS server declaration directives that are not contained within a 'path' -block define the default SOCKS server. If torsocks needs to connect to a machine -via a SOCKS server (i.e it isn't a network declared as 'local') and no 'path' -has declared it can reach that network via a 'reaches' directive this server -is used to negotiate the connection. - -.SH CONFIGURATION SYNTAX - -The basic structure of all lines in the configuration file is: - -.RS -<directive> = <parameters> -.RE - -The exception to this is 'path' blocks which look like: - -.RS -path { -.RS -<directive> = <parameters> -.RE -} -.RE - -Empty lines are ignored and all input on a line after a '#' character is -ignored. - -.SS DIRECTIVES -The following directives are used in the torsocks configuration file: - -.TP -.I server -The IP address of the SOCKS server (e.g "server = 10.1.4.253"). Only one -server may be specified per path block, or one outside a path -block (to define the default server). Unless \-\-disable-hostnames was -specified to configure at compile time the server can be specified as -a hostname (e.g "server = socks.nec.com") - -.TP -.I server_port -The port on which the SOCKS server receives requests. Only one server_port -may be specified per path block, or one outside a path (for the default -server). This directive is not required if the server is on the -standard port (1080). - -.TP -.I server_type -SOCKS version used by the server. Versions 4 and 5 are supported (but both -for only the connect operation). The default is 4. Only one server_type -may be specified per path block, or one outside a path (for the default -server). - -You can use the inspectorsocks utility to determine the type of server, see -the 'UTILITIES' section later in this manual page. - -.TP -.I default_user -This specifies the default username to be used for username and password -authentication in SOCKS version 5. In order to determine the username to -use (if the socks server requires username and password authentication) -torsocks first looks for the environment variable TSOCKS_USERNAME, then -looks for this configuration option, then tries to get the local username. -This option is not valid for SOCKS version 4 servers. Only one default_user -may be specified per path block, or one outside a path (for the default -server) - -.TP -.I default_pass -This specified the default password to be used for username and password -authentication in SOCKS version 5. In order to determine the password to -use (if the socks server requires username and password authentication) -torsocks first looks for the environment variable TSOCKS_PASSWORD, then -looks for this configuration option. This option is not valid for SOCKS -version 4 servers. Onle one default_pass may be specified per path block, -or one outside a path (for the default server) - -.TP -.I local -An IP/Subnet pair specifying a network which may be accessed directly without -proxying through a SOCKS server (e.g "local = 10.0.0.0/255.0.0.0"). -Obviously all SOCKS server IP addresses must be in networks specified as -local, otherwise torsocks would need a SOCKS server to reach SOCKS servers. - -.TP -.I reaches -This directive is only valid inside a path block. Its parameter is formed -as IP[:startport[\-endport]]/Subnet and it specifies a network (and a range -of ports on that network) that can be accessed by the SOCKS server specified -in this path block. For example, in a path block "reaches = -150.0.0.0:80-1024/255.0.0.0" indicates to torsocks that the SOCKS server -specified in the current path block should be used to access any IPs in the -range 150.0.0.0 to 150.255.255.255 when the connection request is for ports -80-1024. - -.TP -.I tordns_enable -This enables the use of the 'tordns' feature in torsocks, which overrides the -standard C library name resolution calls to use SOCKS. The default value is -`true'. - -.TP -.I tordns_deadpool_range -Tor hidden sites do not have real IP addresses.

Also, tordns is enabled +by default. + +./configure +make +make install + +All the tordns config options have sane default values which you should +not need to change. + + +Why did I need to use 'tor-resolve' with 'torify' in the first place? +--------------------------------------------------------------------- + +Because if you run "torify telnet bar.foo.com 31337", for example, then +you're leaking information about what sites you're visiting to DNS servers. + +The tor-resolve utility resolves names through tor using SOCKS, in a way +that shouldn't compromise your privacy. + + +What won't work with this? +-------------------------- + +The 'tordns' feature for tsocks only works with applications using the +standard c library name lookup mechanisms. + +Some programs roll their own name lookup functions, for example, 'curl' +uses the 'adns' library, not the standard c library name lookup calls. +In this case, you'll still be leaking DNS requests. + +However, it seems that most programs which go to the trouble of implementing +asynchronous DNS requests or doing other tricky things have native SOCKS or +HTTP proxy support. + +Requests for reverse name lookups are not intercepted. + +Finally, the tsocks library is NOT thread-safe, with or without this patch. +You should not 'torify' multithreaded applications. + + +How does it work? +----------------- + +This patch adds interceptors for common name resolution calls to tsocks. +Specifically, the 'gethostbyname', 'getaddrinfo' and 'getipnodebyname' library +functions. (gethostbyname_r is not supported). + +When a call to one of these functions is intercepted, a SOCKS4A resolve +request is used to retrieve the relevant information, and the results are +cached. + +When the application calls 'connect', the cache is consulted and instead +of making a SOCKS5 request and supplying the IP address, we connect using +the name. This prevents those messages in the tor logs which look like: + + Sep 23 10:12:20.901 [warn] fetch_from_buf_socks(): Your application (using s + ocks5 on port 80) is giving Tor only an IP address. Applications that do DNS + resolves themselves may leak information. Consider using Socks4A (e.g. via + privoxy or socat) instead. + +There are special provisions for handling .onion sites. When a program asks +to resolve a name ending in '.onion', no name lookup is performed. A bogus IP +address is returned. The range of unused IP addresses to hand out is called the +"deadpool". This IP address doesn't mean anything in particular, and could be +considered a cookie associated with the name. When the application eventually +calls 'connect' with this bogus IP, the cache is consulted and the result is a +SOCKS5 request which includes the name of the .onion site. + +The default deadpool range is '127.0.69.0/255.255.255.0'. NOTE: if a resolve +request results in an IP from the deadpool range then the response is rejected, +and it appears to the application that the lookup failed. + +The lookup cache is kept in mmap'd memory and shared across fork() calls. +This is because some programs perform name lookups in a child process and +then invoke 'connect' in the parent as a kind of "poor man's async DNS". + + +Advanced configuration options +------------------------------ + +The following options have been added to the tsocks configuration file: + +tordns_enable + + The default value is 'true'. If you set it to 'false', tsocks should work + just like it did without the tordns patch. + + +tordns_deadpool_range + + The default value is '127.0.69.0/255.255.255.0'. This specifies what range + of IP addresses will be handed to the application as "cookies" for .onion + names. Of course, you should pick a block of addresses which you aren't + going to ever need to actually connect to. + + +tordns_cache_size + + This specifies the number of IP addresses looked up through socks to cache. + The default value is 256. The default value is 256. Each entry consumes 260 + bytes of memory, so the default adds 66,560 bytes of overhead to each + 'torified' process. NOTE: if the number of IP addresses in + tordns_deadpool_range is less than the value specified for tordns_cache_size, + then the cache will be shrunk to fit the deadpool range. This is to prevent + duplicate deadpool addresses from ever appearing in the cache. + + +TODO +---- + +* Think about how local names get resolved. Is it important? For example, + if I 'telnet localhost' which using tordns, what should happen? Should + we search through /etc/hosts ourselves or what? + +* What about the isc library calls like res_init and so on?

Also, 'torify' now works directly with SSH without ++the need for connect scripts or other fiddling. [As long as SSH is not ++installed suid root]. ++ ++* It allows you to use programs which are not SOCKS aware to connect to ++.onion sites. ++ ++For example, you can ssh directly to a .onion site, or use telnet / netcat ++without hassle. ++ ++ ++QUICK: what do I need to do to make it work? ++-------------------------------------------- ++ ++Configuration instructions: ++ ++1) Get the sources ++ ++wget http://ftp1.sourceforge.net/tsocks/tsocks-1.8beta5.tar.gz ++wget http://www.totalinfosecurity.com/patches/tor-tsocks/tordns-1.8b5.patch ++ ++2) Unpack and apply the tsocks patch ++ ++tar xzvf tsocks-1.8beta5.tar.gz ++cd tsocks-1.8 ++patch -p1 < ../tordns-1.8b5.patch ++ ++3) Configure, compile and install ++ ++NOTE: The default 'configure' settings for tsocks have been changed by ++this patch. The --disable-hostnames option (don't try to use DNS to look ++up SOCKS servers) is now enabled by default. Also, tordns is enabled ++by default. ++ ++./configure ++make ++make install ++ ++All the tordns config options have sane default values which you should ++not need to change. ++ ++ ++Why did I need to use 'tor-resolve' with 'torify' in the first place? ++--------------------------------------------------------------------- ++ ++Because if you run "torify telnet bar.foo.com 31337", for example, then ++you're leaking information about what sites you're visiting to DNS servers. ++ ++The tor-resolve utility resolves names through tor using SOCKS, in a way ++that shouldn't compromise your privacy. ++ ++ ++What won't work with this? ++-------------------------- ++ ++The 'tordns' feature for tsocks only works with applications using the ++standard c library name lookup mechanisms. ++ ++Some programs roll their own name lookup functions, for example, 'curl' ++uses the 'adns' library, not the standard c library name lookup calls. ++In this case, you'll still be leaking DNS requests. ++ ++However, it seems that most programs which go to the trouble of implementing ++asynchronous DNS requests or doing other tricky things have native SOCKS or ++HTTP proxy support. ++ ++Requests for reverse name lookups are not intercepted. ++ ++Finally, the tsocks library is NOT thread-safe, with or without this patch. ++You should not 'torify' multithreaded applications. ++ ++ ++How does it work? ++----------------- ++ ++This patch adds interceptors for common name resolution calls to tsocks. ++Specifically, the 'gethostbyname', 'getaddrinfo' and 'getipnodebyname' library ++functions. (gethostbyname_r is not supported). ++ ++When a call to one of these functions is intercepted, a SOCKS4A resolve ++request is used to retrieve the relevant information, and the results are ++cached. ++ ++When the application calls 'connect', the cache is consulted and instead ++of making a SOCKS5 request and supplying the IP address, we connect using ++the name. This prevents those messages in the tor logs which look like: ++ ++ Sep 23 10:12:20.901 [warn] fetch_from_buf_socks(): Your application (using s ++ ocks5 on port 80) is giving Tor only an IP address. Applications that do DNS ++ resolves themselves may leak information. Consider using Socks4A (e.g. via ++ privoxy or socat) instead. ++ ++There are special provisions for handling .onion sites. When a program asks ++to resolve a name ending in '.onion', no name lookup is performed. A bogus IP ++address is returned. The range of unused IP addresses to hand out is called the ++"deadpool". This IP address doesn't mean anything in particular, and could be ++considered a cookie associated with the name. When the application eventually ++calls 'connect' with this bogus IP, the cache is consulted and the result is a ++SOCKS5 request which includes the name of the .onion site. ++ ++The default deadpool range is '127.0.69.0/255.255.255.0'. NOTE: if a resolve ++request results in an IP from the deadpool range then the response is rejected, ++and it appears to the application that the lookup failed. ++ ++The lookup cache is kept in mmap'd memory and shared across fork() calls. ++This is because some programs perform name lookups in a child process and ++then invoke 'connect' in the parent as a kind of "poor man's async DNS". ++ ++ ++Advanced configuration options ++------------------------------ ++ ++The following options have been added to the tsocks configuration file: ++ ++tordns_enable ++ ++ The default value is 'true'. If you set it to 'false', tsocks should work ++ just like it did without the tordns patch. ++ ++ ++tordns_deadpool_range ++ ++ The default value is '127.0.69.0/255.255.255.0'. This specifies what range ++ of IP addresses will be handed to the application as "cookies" for .onion ++ names. Of course, you should pick a block of addresses which you aren't ++ going to ever need to actually connect to. ++ ++ ++tordns_cache_size ++ ++ This specifies the number of IP addresses looked up through socks to cache. ++ The default value is 256. The default value is 256. Each entry consumes 260 ++ bytes of memory, so the default adds 66,560 bytes of overhead to each ++ 'torified' process. NOTE: if the number of IP addresses in ++ tordns_deadpool_range is less than the value specified for tordns_cache_size, ++ then the cache will be shrunk to fit the deadpool range. This is to prevent ++ duplicate deadpool addresses from ever appearing in the cache. ++ ++ ++TODO ++---- ++ ++* Think about how local names get resolved. Is it important? For example, ++ if I 'telnet localhost' which using tordns, what should happen?

(gethostbyname_r is not supported). -+ -+When a call to one of these functions is intercepted, a SOCKS4A resolve -+request is used to retrieve the relevant information, and the results are -+cached. -+ -+When the application calls 'connect', the cache is consulted and instead -+of making a SOCKS5 request and supplying the IP address, we connect using -+the name. This prevents those messages in the tor logs which look like: -+ -+ Sep 23 10:12:20.901 [warn] fetch_from_buf_socks(): Your application (using s -+ ocks5 on port 80) is giving Tor only an IP address. Applications that do DNS -+ resolves themselves may leak information. Consider using Socks4A (e.g. via -+ privoxy or socat) instead. -+ -+There are special provisions for handling .onion sites. When a program asks -+to resolve a name ending in '.onion', no name lookup is performed. A bogus IP -+address is returned. The range of unused IP addresses to hand out is called the -+"deadpool". This IP address doesn't mean anything in particular, and could be -+considered a cookie associated with the name. When the application eventually -+calls 'connect' with this bogus IP, the cache is consulted and the result is a -+SOCKS5 request which includes the name of the .onion site. -+ -+The default deadpool range is '127.0.69.0/255.255.255.0'. NOTE: if a resolve -+request results in an IP from the deadpool range then the response is rejected, -+and it appears to the application that the lookup failed. -+ -+The lookup cache is kept in mmap'd memory and shared across fork() calls. -+This is because some programs perform name lookups in a child process and -+then invoke 'connect' in the parent as a kind of "poor man's async DNS". -+ -+ -+Advanced configuration options -+------------------------------ -+ -+The following options have been added to the tsocks configuration file: -+ -+tordns_enable -+ -+ The default value is 'true'. If you set it to 'false', tsocks should work -+ just like it did without the tordns patch. -+ -+ -+tordns_deadpool_range -+ -+ The default value is '127.0.69.0/255.255.255.0'. This specifies what range -+ of IP addresses will be handed to the application as "cookies" for .onion -+ names. Of course, you should pick a block of addresses which you aren't -+ going to ever need to actually connect to. -+ -+ -+tordns_cache_size -+ -+ This specifies the number of IP addresses looked up through socks to cache. -+ The default value is 256. The default value is 256. Each entry consumes 260 -+ bytes of memory, so the default adds 66,560 bytes of overhead to each -+ 'torified' process. NOTE: if the number of IP addresses in -+ tordns_deadpool_range is less than the value specified for tordns_cache_size, -+ then the cache will be shrunk to fit the deadpool range. This is to prevent -+ duplicate deadpool addresses from ever appearing in the cache. -+ -+ -+TODO -+---- -+ -+* Think about how local names get resolved. Is it important? For example, -+ if I 'telnet localhost' which using tordns, what should happen?

[metrics-web/master] Accept empty start or end dates.

commit b67e014ad4fbfb03a7f44b3f75affef81c2bd5fa Author: Karsten Loesing <karsten.loesing(a)gmx.net> Date: Sun Feb 27 12:47:57 2011 +0100 Accept empty start or end dates. So far we required that either both start and end date are provided, or none of them. Now we also accept the two cases when only one of the two dates is provided. If no end date is provided, we set it to today. If no start date is provided, we set it to 90 days before the end date. This does not affect the cases when both dates are provided (in which case we use the provided dates), or when none are provided (in which case we use today as the end date and today - 90 days as the start date). --- .../ernie/web/GraphParameterChecker.java | 54 ++++++++----------- 1 files changed, 23 insertions(+), 31 deletions(-) diff --git a/src/org/torproject/ernie/web/GraphParameterChecker.java b/src/org/torproject/ernie/web/GraphParameterChecker.java index 20914a8..caeee06 100644 --- a/src/org/torproject/ernie/web/GraphParameterChecker.java +++ b/src/org/torproject/ernie/web/GraphParameterChecker.java @@ -92,50 +92,42 @@ public class GraphParameterChecker { Map<String, String[]> recognizedGraphParameters = new HashMap<String, String[]>(); - /* Parse start and end dates if supported by the graph type.
