For more -information on this configuration see the CAVEATS section of this -manual page. +Set @LDPRELOAD@ to load the library then use applications as normal. The syntax +to force preload of the library for different shells is specified below: -.SH DESCRIPTION +Bash, Ksh and Bourne shell: -.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 the -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. +$ export LD_PRELOAD=/path/to/libtorsocks.so + +C Shell: + +$ setenv LD_PRELOAD=/path/to/libtorsocks.so + +This process can be automated (for Bash, Bourne and Korn shell users) for a +single command or for all commands in a shell session by using the +\fBtorsocks(1)\fP script. + +You can also setup \fBtorsocks(1)\fP in such a way that all processes +automatically use it, a very useful configuration.

(default: 1) + +.PP +.IP TORSOCKS_LOG_FILE_PATH +If set, torsocks will log in the file set by this variable. (default: stderr) + +.SH KNOWN ISSUES + +.SS DNS +Torsocks is not able to send DNS queries through Tor since UDP is not +supported. Thus, any UDP socket is denied. However, DNS queries that can be +intercept are sent to Tor and sent back to the caller. .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. +Torsocks might generate error messages and print them to stderr when there are +problems with the configuration file or the SOCKS negotiation with the Tor +daemon. The TORSOCKS_LOG_LEVEL environment variable controls that behavior as +well as the log file option. Keep in mind that this library can output on the +stderr of the application. -.SH FILES -@CONFDIR@/torsocks.conf - default torsocks configuration file +.SH LIMITATIONS -.SH SEE ALSO -torsocks.conf(5) -torsocks(1) -usewithtor(1) +Outgoing TCP connections can only be proxified through the Tor network. -.SH AUTHOR -Shaun Clowes (delius(a)progsoc.uts.edu.au) +Torsocks forces 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. -.SH COPYRIGHT -Copyright 2000 Shaun Clowes +Torsocks uses ELF dynamic loader features to intercept dynamic function calls +from programs in which it is embedded.

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 +If TORSOCKS_CONF_FILE is not set, torsocks will attempt to read the +configuration file at @CONFDIR@/tor/torsocks.conf.
