+.Nd configuration file for Modula-3 socks clients
+.Sh DESCRIPTION
+The Modula-3 SOCKS library reads its configuration information from 
+.Pa /usr/local/etc/m3socks.conf
+when
+.Fn bind
+or
+.Fn connect
+is called.
+If the file does not exist, then the environment variable
+.Ev SOCKS_CONF
+is expected to give the name of the configuration file.
+.Pp
+Each non-blank, non-comment line in the file contains a direction on how
+to process requests that match certain criteria.
+Comments are denoted by a
+.Ql #
+at any point in the line prior to the
+.Ic : Ns Ar shellcmd ,
+if present.
+Non-comment lines take the form:
+.Pp
+.Bl -item -compact
+.It
+.Ic bind default Ns \*(Ba Ns Ic wild

+Fields are constructed as follows:
+.Bl -tag -width Fl
+.It Ar domain
+The
+.Dq local
+domain:  the default name resolver is assumed to have
+information for all hosts in 
+.Ar domain .
+The user can override this field using the
+.Ev SOCKS_LOCAL_DOMAIN
+environment variable.
+To indicate that the default server is able to resolve all addresses,
+use the command:
+.Ql domain \&. .
+.It Ar nameserver
+A comma separated list of name servers that are able to resolve addresses
+outside of
+.Ar domain .
+The user can override this field using the
+.Ev SOCKS_NS
+environment variable.
+.It Ar findserver
+One of
+.Ic Yes
+or
+.Ic \&No .
+The default is
+.Ic Yes .
+If set, the client will attempt to find the
+.Dq best
+SOCKS server, based
+on the results of looking up
+.Ar destnet Ns Ic .socks-addr
+(note that this is not an FQDN).
+.Ar destnet
+consists of the first one, two, or three octets of the destination network,
+depending on whether the destination network is class A, B, or C.  The octets
+are used in reverse order, just like
+.Ic IN-ADDR.ARPA .
+For example, if the destination address is 129.105.69.100, then a search for
+TXT records for '105.129.socks-addr' would be made.  If any TXT records are
+found, the record is prepended
+to the list of servers from the config file.  There is no environment
+variable to override this.
+.Pp
+If clear
+.Pq Ic findserver Ic \&No ,
+then the lookup is not performed.
+.It Ar server
+A comma separated list of SOCKS servers that can
+be used as proxy for this destination.  No spaces or tabs are allowed
+inside the list.  Names beginning with a
+.Ql $
+are expanded from the users
+environment.  Each server in the list is tried until a successful
+connection is established.  When a server has multiple addresses, it
+is assumed to be a group of hosts: the address list is randomized and
+each address is tried before proceeding to the next name in the list.
+The user can override this field using the
+.Ev SOCKS_SERVER
+environment variable.
+.It Ar users
+Specifies the users on the requesting host (not the destination host
+or server host) to whom this line should apply.  This is a comma
+separated list of names and/or filenames, with no spaces or tabs.
+Filenames must be fully qualified with a leading
+.Ql / .
+Inside the file, user names may be listed one or several
+per line, with spaces, tabs, and commas being valid separators.
+The appearance of
+.Ql #
+marks the remainder of the line as a comment.  Each line in a file
+is limited to 1023 characters.  If
+.Ar users
+is omitted, the line applies to all users.
+.It Ar destspec
+The destination specification, which is either
+.Ar daddr dmask
+or
+.Ic *. Ns Ar some.domain ,
+which indicates that the line applies to all IP addresses
+whose reverse lookup, using 
+.Fn gethostbyaddr ,
+produces a name ending in
+.Ql Cm . Ns Ar some.domain .
+.It Ar daddr
+The destination address to which this line applies.  This is
+usually specified in dotted form (e.g., 15.28.96.137).
+If a hostname is used, then the first address returned by
+.Fn gethostbyname
+is used.
+.It Ar dmask
+Mask for
+.Ar daddr ,
+in dotted form.  Bits in
+.Ar dmask
+which are 0 are ignored in
+.Ar daddr .
+Specifying 255.255.255.255 requires an exact match, while 0.0.0.0 matches
+regardless of the value of
+.Ar daddr .
+This is the same way netmasks are specified, and is the opposite
+of the interpretation used in older versions of SOCKS.
+.It Ar op dport Op Ar dport2
+A constraint on the destination TCP port.
+If
+.Ar op
+is
+.Ic eq ,
+.Ic neq ,
+.Ic \&lt ,
+.Ic gt ,
+.Ic le ,
+or
+.Ic ge ,
+the destination port must have the corresponding relation to
+.Ar dport .
+If
+.Ar op
+is
+.Ic btw ,
+the destination port must be between
+.Ar dport
+and 
+.Ar dport2 ,
+inclusive.
+.It Ic : Ns Ar shellcmd
+When the line is matched,
+.Ar shellcmd
+is passed to
+.Pa /bin/sh ,
+with stdin, stdout, and stderr redirected to
+.Pa /dev/null .
+The following substitutions occur before the string
+is presented to the shell:
+.Bl -tag -width \&%Xxx
+.It Cm \&%A
+replaced by the client host's domainname if known,
+by its IP address otherwise.
+.It Cm \&%a
+replaced by the client host's IP address.
+.It Cm \&%c
+replaced by
+.Ql connect
+or
+.Ql bind .
+.It Cm \&%p
+replaced by the process id of the client program.
+.It Cm \&%S
+replaced by the service name (e.g., ftp) if known,
+by the destination port number otherwise.
+.It Cm \&%s
+replaced by the destination port number.
+.It Cm \&%U
+replaced by the user-id at login.
+.It Cm \&%u
+replaced by the effective user-id.
+.It Cm \&%Z
+replaced by the destination host's domainname if known,
+by its IP address otherwise.
+.It Cm \&%z
+replaced by the destination host's IP address.
+.It Cm \&%%
+replaced by a single
+.Ql \&% .
