+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+ The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. You can give `configure'
+initial values for variables by setting them in the environment. Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+ CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+ env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory. After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on. Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+ CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+ If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+INTRO
+=====
+
+Active port forwarder is a software tool for secure port forwarding.
+It uses ssl to increase security of communication between a server and a client.
+Originally, it was developed to forward data point to point. However, the need
+for bypassing firewalls in order to connect to internally located computers
+influenced the further development of the project.
+
+AF is dedicated for people, who don't have an external ip number and want to
+make some services available across the net.
+
+Moreover, zlib is used to compress the transferred data.
+
+Using one, permanent data/control channel with flow control / packet buffering
+provides good performance and reasonably small latency.
+
+Multiple clients allow to create more sophisticated tunneling scheme.
+
+================================================================================

+
+================================================================================
+
+========================
+3. REMOTE ADMINISTRATION
+========================
+
+ 3.1 Usage
+ ---------
+
+Afclient can be started in remote administration mode by '-r, --remoteadmin'
+option. Required option: '-n, --servername NAME'.
+
+After successful authorization stdin/stdout is used to communicate with user.
+All the commands parsing is done by afserver.
+
+ 3.2 Commands
+ ------------
+
+Currently available commands are:
+
+ help
+ display help
+
+ lcmd
+ lists available commands
+
+ info
+ prints info about server
+
+ rshow
+ display realms
+
+ cshow X
+ display clients in X realm
+
+ ushow X
+ display users in X realm
+
+ quit
+ quit connection
+
+ timeout N X
+ set timeout value in X realm
+
+ audit {0|1} X
+ set audit mode in X realm
+
+ dnslookups {0|1} X
+ set dnslookups mode in X realm
+
+ dateformat S
+ set dateformat
+
+ kuser S
+ kick user named S
+
+ kclient N
+ kick client with number N
+
+
+ 3.3 States
+ ----------
+
+ 3.3.1 Users
+ -----------
+
+ Connected users can be in several states:
+
+ running
+ user is properly connected and can send/receive data
+
+ opening
+ user is connected to afserver, but afclient hasn't confirmed connection
+ with the destination. There is no traffic allowed in this situation.
+
+ opening (closed)
+ user was in 'opening' state, but 'kuser' command has been used and it's
+ now queued for closing as soon as afclient will be ready to confirm
+ this
+
+ stopped
+ user wasn't responsible, so all the packets addressed to it are queued.
+ Afclient is informed to not receive any packets for this user.
+
+ closing
+ connection with user has been lost. Afclient has to confirm user
+ deletion
+
+ unknown
+ probably afserver internal state has been corrupted.
+
+
+ 3.3.2 Clients
+ -------------
+
+ Connected clients can be in several states:
+
+ running
+ client is properly connected and can serve user's requests
+
+ ssl handshake
+ connection with client has been initialized and now ssl routines are
+ negotiating all the details needed to establish secure tunnel. This
+ stage with 'authorization' must not exceed the time set by 'timeout'
+ option.
+
+ authorization
+ ssl tunnel is ready and afclient has to authorize itself to the
+ afserver. This stage with 'ssl handshake' must not exceed the time set
+ by 'timeout' option.
+
+ unknown
+ probably afserver internal state has been corrupted.
+
+
+ 3.4 Relay mode
+ --------------
+
+Afclient with '-p, --portnum PORT' option listens for connection from user at
+NAME:PORT. NAME is set by '-d, --hostname' option or hostname() function, when
+the option is missing.
+
+When user quits (close the connection or send 'quit' command), afclient exits.
+
+================================================================================
+
+=====================
+4. HTTP PROXY TUNNELS
+=====================
+
+Afclient can communicate with afserver via HTTP proxy. In order to use this
+feature, afserver must be started with '-P, --enableproxy' option. Afclient must
+specify the proxy host ('-P, --proxyname' option) and port ('-X, --proxyport'
+option).
+
+Afclient with HTTP proxy mode enabled can still accept connections from
+afclients, which don't use HTTP proxy mode.
+
+================================================================================
+
+==========
+5. LOGGING
+==========
+
+Logging can be enabled by '-o, --log' option. The argument to this option must
+be in the form:
+ target,description,msgdesc
+
+Where
+ target is file or sock
+ description is filename or host,port
+ msgdesc is the subset of:
+ LOG_T_ALL,
+ LOG_T_USER,
+ LOG_T_CLIENT,
+ LOG_T_INIT,
+ LOG_T_MANAGE,
+ LOG_T_MAIN,
+ LOG_I_ALL,
+ LOG_I_CRIT,
+ LOG_I_DEBUG,
+ LOG_I_DDEBUG,
+ LOG_I_INFO,
+ LOG_I_NOTICE,
+ LOG_I_WARNING,
+ LOG_I_ERR
+
+ written without spaces.
+
+
+ Example:
+
+ file,filename,LOG_T_MANAGE,LOG_I_ALL
+
+================================================================================
+
+==========
+6. MODULES
+==========
+
+Afclient can use external modules for user's packets filtering ('-l, --load')
+and service's packets filtering ('-L, --Load'). Module file has to declare three
+functions:
+
+char* info(void);
+
+ info() return values:
+ - info about module
+
+ Example:
+
+ char*
+ info(void)
+ {
+ return "Module tester v0.1";
+ }
+
+int allow(char* host, char* port);
+
+ allow() return values:
+ 0 - allow to connect
+ !0 - drop the connection
+
+ Example:
+
+ int
+ allow(char* host, char* port)
+ {
+ return 0; /* allow to connect */
+ }
+
+int filter(char* host, unsigned char* message, int* length);
+
+ filter() return values:
+ 0 - allow to transfer
+ 1 - drop the packet
+ 2 - drop the connection
+ 3 - release the module
+ 4 - drop the packet and release the module
+ 5 - drop the connection and release the module
+
+ Example:
+
+ int
+ filter(char* host, unsigned char* message, int* length)
+ {
+ int i;
+ for (i = 1; i < *length; ++i) {
+ if (message[i-1] == 'M') {
+ if (message[i] == '1') {
+ return 1; /* ignored */
+ }
+ if (message[i] == '2') {
+ return 2; /* dropped */
+ }
+ if (message[i] == '3') {
+ return 3; /* release */
+ }
+ if (message[i] == '4') {
+ return 4; /* ignored + release */
+ }
+ if (message[i] == '5') {
+ return 5; /* dropped + release */
+ }
+ }
+ }
+ return 0; /* allow to transfer */
+ }
+
+Modules have to be compiled with '-fPIC -shared' options.
+
+================================================================================
+
+================
+7. MULTI TUNNELS
+================
+
+Since version 0.8 it's possible to transfer multiple tunnels in the one
+afclient <-> afserver connection.
+
+On the afserver we have to specify multiple listen ports with the same manage
+port.
+
+When we set several '-p' options on the afclient, the new user connections will
+be distributed according to the sequence of the options, i.e. new user
+connecting to the second UsrCli pair (with the same manage ports) will be
+transferred to the destination pointed by the second '-p' option.
+
+================================================================================
+
+===========
+8. EXAMPLES
+===========
+
+ 8.1 tcp mode
+ ------------
+
+ local network |FireWall| Internet
+ ||
+ || User 1
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || | \(tcp)
+ /(tcp) || (tcp)| User 2
+ / || \
+ Http server || User 3
+ ||
+
+
+The use of it is extremely simple. Let's suppose we want to create a http server
+on our computer and we are behind a masquerade or a firewall:
+
+1) We have to find some machine on the net with an external ip and a shell
+ account.
+
+2) Use "make" to compile everything on that machine. (you can freely remove the
+ afclient and client.rsa files)
+
+3) You can edit the config file or just type from the console (to use the config
+ type -f <cfgfile>) :
+ $ ./afserver
+ This will work, if you want to use default values:
+ - hostname will be taken from hostname function (it would be ideally, if
+ there is appropriate registration in /etc/hosts)
+ - server will be listening for users on port 50127
+ - server will be listening for client on port 50126
+ - server will be for maximum 5 users
+ - server will forward tcp packets
+ - there will be no logging and no verbose messages
+ - there will be no password identification
+ - ip protocol family will be unspecified
+
+4) We use "make" on our machine (we can delete everything apart from afclient
+ and client.rsa)
+
+5) We are typing from the console:
+ $ ./afclient -n <name of the server> -p 80
+ Where <name of the server> is a string like : 'bastion.univ.gda.pl' or
+ '153.19.7.200'
+
+6) We can now enter with a web-browser to: <name of the server>:50127 and we
+ will enter to our computer in the fact.
+
+ 8.2 reverse udp mode
+ --------------------
+
+ local network |FireWall| Internet
+ || (udp)
+ || User 1-------AF Client
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || |
+ /(udp) || (tcp)|
+ / || /
+ Game server || AF Client-------User 2
+ || (udp)
+
+
+Let's see how to use af to forward udp packets. Suppose we want to create a game
+server on our computer (udp port 27960 on our machine):
+
+1) - 4) is the same like in example 1. (but we add option: -p udp)
+
+5) We are typing from the console:
+ $ ./afclient -u -n <name of the server> -p 27960
+ Where <name of the server> is a name (or ip) of a host where our server is
+ running.
+
+6) Connecting to our game is more complicated. The user must use afclient to do
+ this. He has to specify the server he is connecting to and the port, which
+ his program will be listening on:
+ $ ./afclient -U -d <hostname> -p <portnum> -n <name of the server> \
+ -m <server port>
+ Where <hostname> is the name of the user machine (who wants to connect to our
+ game). <portnum> is the port he will be connecting to. <name of the server>
+ is the name of the host where our server is running. <server port> is the
+ port on which the server is listening for users. In order to connect to our
+ game, the user has to connect to <hostname>:<portnum>.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+# Check whether `mkdir -p' is supported, fallback to mkinstalldirs otherwise.
+#
+# Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
+# created by `make install' are always world readable, even if the
+# installer happens to have an overly restrictive umask (e.g. 077).
+# This was a mistake. There are at least two reasons why we must not
+# use `-m 0755':
+# - it causes special bits like SGID to be ignored,
+# - it may be too restrictive (some setups expect 775 directories).
+#
+# Do not use -m 0755 and let people choose whatever they expect by
+# setting umask.
+#
+# We cannot accept any implementation of `mkdir' that recognizes `-p'.
+# Some implementations (such as Solaris 8's) are not thread-safe: if a
+# parallel make tries to run `mkdir -p a/b' and `mkdir -p a/c'
+# concurrently, both version can detect that a/ is missing, but only
+# one can create it and the other will error out. Consequently we
+# restrict ourselves to GNU make (using the --version option ensures
+# this.)

+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+.SH DESCRIPTION
+.B Afclient
+is a port forwarding program designed to be efficient and easy to use. It connects to
+.B afserver
+to listenport (default listenport is 50126) and after a successful authorization
+.B afclient
+redirects all the data to the specified destination host:port.
+.SH "EXAMPLES"
+.B afclient -n servername -p 22
+ program connects to servername:50126 and redirects data to local port 22 (becomes a daemon)
+
+.B afclient -n servername -p 22 -v

+
+ Example:
+
+ file,logfile,LOG_T_USER,LOG_T_CLIENT,LOG_I_INFO,LOG_I_NOTICE
+
+.SH MODULES
+
+.B Afclient
+can use external modules for user's packets filtering
+.RB ( "'-l, --load'" )
+and service's packets filtering
+.RB ( "'-L, --Load'" ).
+Module file has to declare three functions:
+
+.BI "char* info(" void );
+
+ info() return values:
+ - info about module
+
+ Example:
+
+ char*
+ info(void)
+ {
+ return "Module tester v0.1";
+ }
+
+.BI "int allow(char* " host ", char* " port );
+
+ allow() return values:

+ int
+ allow(char* host, char* port)
+ {
+ return 0; /* allow to connect */
+ }
+
+.BI "int filter(char* " host ", unsigned char* " message ", int* " length );
+
+ filter() return values:
+ 0 - allow to transfer
+ 1 - drop the packet
+ 2 - drop the connection
+ 3 - release the module
+ 4 - drop the packet and release the module
+ 5 - drop the connection and release the module
+
+ Example:
+
+ int
+ filter(char* host, unsigned char* message, int* length)
+ {
+ int i;
+ for (i = 1; i < *length; ++i) {
+ if (message[i-1] == 'M') {
+ if (message[i] == '1') {
+ return 1; /* ignored */
+ }
+ if (message[i] == '2') {
+ return 2; /* dropped */
+ }
+ if (message[i] == '3') {
+ return 3; /* release */
+ }
+ if (message[i] == '4') {
+ return 4; /* ignored + release */
+ }
+ if (message[i] == '5') {
+ return 5; /* dropped + release */
+ }
+ }
+ }
+ return 0; /* allow to transfer */
+ }
+
+Modules have to be compiled with
+.B -fPIC -shared
+options.

+.SH NAME
+afclient.conf \- Configuration File for afclient
+.SH INTRODUCTION
+.B Afclient
+supports several mechanisms to supply configuration and run-time parameters: command line options,
+.B afclient.conf
+and hard-coded defaults. When the same information is supplied in more than one way, the highest precedence mechanism is used. When configuration file is used (option:
+.IR "-f FILE")
+command line options like
+.IR --reverseudp ,
+.IR --udpmode ,
+.IR --remoteadmin ,
+.IR --load ,
+.I --Load
+and
+.I --pass
+are ignored. Options from configuration file are taken before values from command line (with the exception of
+.IR --keyfile ,
+.IR --storefile ,
+.IR --dateformat ,
+.IR --ignorepkeys
+and the options connected with http proxy and auto-reconnect support). When something is not declared, hard-coded values are used.
+

+.SH NAME
+afserver.conf \- Configuration File for afserver
+.SH INTRODUCTION
+.B Afserver
+supports several mechanisms to supply configuration and run-time parameters: command line options,
+.B afserver.conf
+and hard-coded defaults. When the same information is supplied in more than one way, the highest precedence mechanism is used. When configuration file is used (option:
+.IR "-f FILE")
+command line options like
+.IR --hostname ,
+.IR --listenport ,
+.I --manageport
+and
+.I --pass
+are ignored. Options from configuration file are taken before values from command line (with the exception of
+.IR --cerfile ,
+.I --keyfile
+and
+.I --dateformat
+). When something is not declared, hard-coded values are used.
+

+INTRO
+=====
+
+Active port forwarder is a software tool for secure port forwarding.
+It uses ssl to increase security of communication between a server and a client.
+Originally, it was developed to forward data point to point. However, the need
+for bypassing firewalls in order to connect to internally located computers
+influenced the further development of the project.
+
+AF is dedicated for people, who don't have an external ip number and want to
+make some services available across the net.
+
+Moreover, zlib is used to compress the transferred data.
+
+Using one, permanent data/control channel with flow control / packet buffering
+provides good performance and reasonably small latency.
+
+Multiple clients allow to create more sophisticated tunneling scheme.

+
+================================================================================
+
+========================
+3. REMOTE ADMINISTRATION
+========================
+
+ 3.1 Usage
+ ---------
+
+Afclient can be started in remote administration mode by '-r, --remoteadmin'
+option. Required option: '-n, --servername NAME'.
+
+After successful authorization stdin/stdout is used to communicate with user.
+All the commands parsing is done by afserver.
+
+ 3.2 Commands
+ ------------
+
+Currently available commands are:
+
+ help
+ display help
+
+ lcmd
+ lists available commands
+
+ info
+ prints info about server
+
+ rshow
+ display realms
+
+ cshow X
+ display clients in X realm
+
+ ushow X
+ display users in X realm
+
+ quit
+ quit connection
+
+ timeout N X
+ set timeout value in X realm
+
+ audit {0|1} X
+ set audit mode in X realm
+
+ dnslookups {0|1} X
+ set dnslookups mode in X realm
+
+ dateformat S
+ set dateformat
+
+ kuser S
+ kick user named S
+
+ kclient N
+ kick client with number N
+
+
+ 3.3 States
+ ----------
+
+ 3.3.1 Users
+ -----------
+
+ Connected users can be in several states:
+
+ running
+ user is properly connected and can send/receive data
+
+ opening
+ user is connected to afserver, but afclient hasn't confirmed connection
+ with the destination. There is no traffic allowed in this situation.
+
+ opening (closed)
+ user was in 'opening' state, but 'kuser' command has been used and it's
+ now queued for closing as soon as afclient will be ready to confirm
+ this
+
+ stopped
+ user wasn't responsible, so all the packets addressed to it are queued.
+ Afclient is informed to not receive any packets for this user.
+
+ closing
+ connection with user has been lost. Afclient has to confirm user
+ deletion
+
+ unknown
+ probably afserver internal state has been corrupted.
+
+
+ 3.3.2 Clients
+ -------------
+
+ Connected clients can be in several states:
+
+ running
+ client is properly connected and can serve user's requests
+
+ ssl handshake
+ connection with client has been initialized and now ssl routines are
+ negotiating all the details needed to establish secure tunnel. This
+ stage with 'authorization' must not exceed the time set by 'timeout'
+ option.
+
+ authorization
+ ssl tunnel is ready and afclient has to authorize itself to the
+ afserver. This stage with 'ssl handshake' must not exceed the time set
+ by 'timeout' option.
+
+ unknown
+ probably afserver internal state has been corrupted.
+
+
+ 3.4 Relay mode
+ --------------
+
+Afclient with '-p, --portnum PORT' option listens for connection from user at
+NAME:PORT. NAME is set by '-d, --hostname' option or hostname() function, when
+the option is missing.
+
+When user quits (close the connection or send 'quit' command), afclient exits.
+
+================================================================================
+
+=====================
+4. HTTP PROXY TUNNELS
+=====================
+
+Afclient can communicate with afserver via HTTP proxy. In order to use this
+feature, afserver must be started with '-P, --enableproxy' option. Afclient must
+specify the proxy host ('-P, --proxyname' option) and port ('-X, --proxyport'
+option).
+
+Afclient with HTTP proxy mode enabled can still accept connections from
+afclients, which don't use HTTP proxy mode.
+
+================================================================================
+
+==========
+5. LOGGING
+==========
+
+Logging can be enabled by '-o, --log' option. The argument to this option must
+be in the form:
+ target,description,msgdesc
+
+Where
+ target is file or sock
+ description is filename or host,port
+ msgdesc is the subset of:
+ LOG_T_ALL,
+ LOG_T_USER,
+ LOG_T_CLIENT,
+ LOG_T_INIT,
+ LOG_T_MANAGE,
+ LOG_T_MAIN,
+ LOG_I_ALL,
+ LOG_I_CRIT,
+ LOG_I_DEBUG,
+ LOG_I_DDEBUG,
+ LOG_I_INFO,
+ LOG_I_NOTICE,
+ LOG_I_WARNING,
+ LOG_I_ERR
+
+ written without spaces.
+
+
+ Example:
+
+ file,filename,LOG_T_MANAGE,LOG_I_ALL
+
+================================================================================
+
+==========
+6. MODULES
+==========
+
+Afclient can use external modules for user's packets filtering ('-l, --load')
+and service's packets filtering ('-L, --Load'). Module file has to declare three
+functions:
+
+char* info(void);
+
+ info() return values:
+ - info about module
+
+ Example:
+
+ char*
+ info(void)
+ {
+ return "Module tester v0.1";
+ }
+
+int allow(char* host, char* port);
+
+ allow() return values:
+ 0 - allow to connect
+ !0 - drop the connection
+
+ Example:
+
+ int
+ allow(char* host, char* port)
+ {
+ return 0; /* allow to connect */
+ }
+
+int filter(char* host, unsigned char* message, int* length);
+
+ filter() return values:
+ 0 - allow to transfer
+ 1 - drop the packet
+ 2 - drop the connection
+ 3 - release the module
+ 4 - drop the packet and release the module
+ 5 - drop the connection and release the module
+
+ Example:
+
+ int
+ filter(char* host, unsigned char* message, int* length)
+ {
+ int i;
+ for (i = 1; i < *length; ++i) {
+ if (message[i-1] == 'M') {
+ if (message[i] == '1') {
+ return 1; /* ignored */
+ }
+ if (message[i] == '2') {
+ return 2; /* dropped */
+ }
+ if (message[i] == '3') {
+ return 3; /* release */
+ }
+ if (message[i] == '4') {
+ return 4; /* ignored + release */
+ }
+ if (message[i] == '5') {
+ return 5; /* dropped + release */
+ }
+ }
+ }
+ return 0; /* allow to transfer */
+ }
+
+Modules have to be compiled with '-fPIC -shared' options.
+
+================================================================================
+
+================
+7. MULTI TUNNELS
+================
+
+Since version 0.8 it's possible to transfer multiple tunnels in the one
+afclient <-> afserver connection.
+
+On the afserver we have to specify multiple listen ports with the same manage
+port.
+
+When we set several '-p' options on the afclient, the new user connections will
+be distributed according to the sequence of the options, i.e. new user
+connecting to the second UsrCli pair (with the same manage ports) will be
+transferred to the destination pointed by the second '-p' option.
+
+================================================================================
+
+===========
+8. EXAMPLES
+===========
+
+ 8.1 tcp mode
+ ------------
+
+ local network |FireWall| Internet
+ ||
+ || User 1
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || | \(tcp)
+ /(tcp) || (tcp)| User 2
+ / || \
+ Http server || User 3
+ ||
+
+
+The use of it is extremely simple. Let's suppose we want to create a http server
+on our computer and we are behind a masquerade or a firewall:
+
+1) We have to find some machine on the net with an external ip and a shell
+ account.
+
+2) Use "make" to compile everything on that machine. (you can freely remove the
+ afclient and client.rsa files)
+
+3) You can edit the config file or just type from the console (to use the config
+ type -f <cfgfile>) :
+ $ ./afserver
+ This will work, if you want to use default values:
+ - hostname will be taken from hostname function (it would be ideally, if
+ there is appropriate registration in /etc/hosts)
+ - server will be listening for users on port 50127
+ - server will be listening for client on port 50126
+ - server will be for maximum 5 users
+ - server will forward tcp packets
+ - there will be no logging and no verbose messages
+ - there will be no password identification
+ - ip protocol family will be unspecified
+
+4) We use "make" on our machine (we can delete everything apart from afclient
+ and client.rsa)
+
+5) We are typing from the console:
+ $ ./afclient -n <name of the server> -p 80
+ Where <name of the server> is a string like : 'bastion.univ.gda.pl' or
+ '153.19.7.200'
+
+6) We can now enter with a web-browser to: <name of the server>:50127 and we
+ will enter to our computer in the fact.
+
+ 8.2 reverse udp mode
+ --------------------
+
+ local network |FireWall| Internet
+ || (udp)
+ || User 1-------AF Client
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || |
+ /(udp) || (tcp)|
+ / || /
+ Game server || AF Client-------User 2
+ || (udp)
+
+
+Let's see how to use af to forward udp packets. Suppose we want to create a game
+server on our computer (udp port 27960 on our machine):
+
+1) - 4) is the same like in example 1. (but we add option: -p udp)
+
+5) We are typing from the console:
+ $ ./afclient -u -n <name of the server> -p 27960
+ Where <name of the server> is a name (or ip) of a host where our server is
+ running.
+
+6) Connecting to our game is more complicated. The user must use afclient to do
+ this. He has to specify the server he is connecting to and the port, which
+ his program will be listening on:
+ $ ./afclient -U -d <hostname> -p <portnum> -n <name of the server> \
+ -m <server port>
+ Where <hostname> is the name of the user machine (who wants to connect to our
+ game). <portnum> is the port he will be connecting to. <name of the server>
+ is the name of the host where our server is running. <server port> is the
+ port on which the server is listening for users. In order to connect to our
+ game, the user has to connect to <hostname>:<portnum>.

+INTRO
+=====
+
+Active port forwarder est un programme permettant de réaliser du forwarding de
+port sécurisé. Il utilise le protocole SSL pour augmenter le niveau de sécurité
+des communications entre serveur et client. Son développement initial comme
+outil de communication point à point a été influencé de façon à permettre le
+contournement de firewalls et les communications à destination d'équipements
+localisés sur le réseau interne.
+
+Af est destiné aux personnes sans adresse IP publique externe qui désirent
+offrir des services accessibles depuis le net.
+
+La librairie Zlib est de plus employée pour compresser les données transférées.
+
+L'utilisation d'un canal contrôle/données permanent avec une gestion de flux et
+une mise en cache des paquets fournit de bonnes performances et un temps de
+latence raisonnablement court.
+
+L'emploi de clients multiples permet la création de schémas de tunneling plus
+sophistiqués.
+

+================================================================================
+
+========
+2. USAGE
+========
+
+ 2.1 afserver
+ ------------
+
+ Basic options:
+
+ -n, --hostname - it's used when creating listening sockets
+ (default: '')
+ -l, --listenport - listening port number - users connect
+ to it (default: 50127)
+ -m, --manageport - manage port number - second part of the active
+ port forwarder connects to it (default: 50126)
+ -h, --help - prints this help
+
+ Authorization:
+
+ --pass - set the password used for client identification
+ (default: no password)
+
+ Configuration:
+
+ -c, --cerfile - the name of the file with certificate
+ (default: cacert.pem)
+ -k, --keyfile - the name of the file with RSA key (default: server.rsa)
+ -f, --cfgfile - the name of the file with the configuration for the
+ active forwarder (server)

+ for details) (default: %d.%m.%Y %H:%M:%S)
+
+ -t, --timeout - the timeout value for the client's connection
+ (default: 5)
+ -u, --users - the amount of users allowed to use this server
+ (default: 5)
+ -C, --clients - the number of allowed clients to use this server
+ (default: 1)
+ -r, --realm - set the realm name (default: none)
+ -R, --raclients - the number of allowed clients in remote administration
+ mode to use this server (default: 1)

+ -M, --climode - strategy used for connecting users with clients
+ (default: 1)
+ Available strategies:
+ 1. fill first client before go to next
+
+ -p, --proto - type of server (tcp|udp) - for which protocol it will
+ be operating (default: tcp)
+ -b, --baseport - listenports are temporary and differ for each client
+ --nossl - ssl is not used for transferring data (but it's still
+ used to establish a connection) (default: ssl is used)
+ --nozlib - zlib is not used for compressing data (default:
+ zlib is used)
+ --dnslookups - try to obtain dns names of the computers rather than
+ their numeric IP
+
+ Logging:
+
+ -O, --heavylog - logging everything to a logfile
+ -o, --lightlog - logging some data to a logfile
+ -S, --heavysocklog - logging everything to a localport
+ -s, --lightsocklog - logging some data to a localport
+ -v, --verbose - to be verbose - program won't enter the daemon mode
+ (use several times for greater effect)
+
+ IP family:
+
+ -4, --ipv4 - use ipv4 only
+ -6, --ipv6 - use ipv6 only
+
+ 2.2 afclient
+ ------------
+
+ Basic options:
+
+ -n, --servername - where the second part of the active
+ port forwarder is running (required)
+ -m, --manageport - manage port number - server must be
+ listening on it (default: 50126)
+ -d, --hostname - the name of this host/remote host - the final
+ destination of the packets (default: the name
+ returned by hostname function)
+ -p, --portnum - the port we are forwarding connection to (required)
+ -h, --help - prints this help
+
+ Authorization:
+
+ -i, --id - send the id string to afserver
+ --pass - set the password used for client identification
+ (default: no password)
+
+ Configuration:

+ for details) (default: %d.%m.%Y %H:%M:%S)
+
+ Modes:
+
+ -u, --udpmode - udp mode - client will use udp protocol to
+ communicate with the hostname
+ -U, --reverseudp - reverse udp forwarding. Udp packets will be forwarded
+ from hostname:portnum (-p) to the server name:portnum
+ (-m)
+ -r, --remoteadmin - remote administration mode. (using '-p #port' will
+ force afclient to use port rather then stdin-stdout)
+
+ Logging:
+
+ -O, --heavylog - logging everything to a logfile
+ -o, --lightlog - logging some data to a logfile
+ -S, --heavysocklog - logging everything to a localport
+ -s, --lightsocklog - logging some data to a localport
+ -v, --verbose - to be verbose - program won't enter the daemon mode
+ (use several times for greater effect)
+
+ IP family:
+
+ -4, --ipv4 - use ipv4 only
+ -6, --ipv6 - use ipv6 only
+
+ Modules:
+
+ -l, --load - load a module for user's packets filtering
+ -L, --Load - load a module for service's packets filtering
+
+================================================================================
+
+==========================
+3. ADMINISTRATION DISTANTE
+==========================
+
+Afclient peut être démarré en mode d'administration distante avec l'option '-r,
+--remoteadmin'. L'option requise est: '-n, --servername NAME'.
+
+Après autorisation, les flux stdin/stdout sont utilisés pour communiquer avec
+l'utilisateur. La prise en compte des commandes est effectuée par afserver.
+
+Les commandes disponibles sont:
+
+ help
+ display help
+
+ lcmd
+ lists available commands
+
+ info
+ prints info about server
+
+ rshow
+ display realms
+
+ cshow X
+ display clients in X realm
+
+ ushow X
+ display users in X realm
+
+ quit
+ quit connection
+
+Afclient se positionne en écoute sur NAME:PORT avec '-p, --portnum PORT'. NAME
+est positionné avec l'option '-d, --hostname' ou par la fonction hostname() si
+l'argument n'est pas fourni.
+
+Quand l'utilisateur quitte (termine la connexion ou envoie la commande 'quit'),
+afclient se termine.
+
+================================================================================
+
+==========
+4. MODULES
+==========
+
+Afclient peut utiliser des modules externes pour le filtrage des paquets ('-l,
+ --load') utilisateurs et pour le filtrage des paquets service ('-L, --Load').
+Le fichier contenant les modules doit déclarer trois fonctions :
+
+char* info(void);
+
+ info() return values:
+ - info about module
+
+ Example:
+
+ char*
+ info(void)
+ {
+ return "Module tester v0.1";
+ }
+
+int allow(char* host, char* port);
+
+ allow() return values:
+ 0 - allow to connect
+ !0 - drop the connection
+
+ Example:
+
+ int
+ allow(char* host, char* port)
+ {
+ return 0; /* allow to connect */
+ }
+
+int filter(char* host, unsigned char* message, int* length);
+
+ filter() return values:
+ 0 - allow to transfer
+ 1 - drop the packet
+ 2 - drop the connection
+ 3 - release the module
+ 4 - drop the packet and release the module
+ 5 - drop the connection and release the module
+
+ Example:
+
+ int
+ filter(char* host, unsigned char* message, int* length)
+ {
+ int i;
+ for (i = 1; i < *length; ++i) {
+ if (message[i-1] == 'M') {
+ if (message[i] == '1') {
+ return 1; /* ignored */
+ }
+ if (message[i] == '2') {
+ return 2; /* dropped */
+ }
+ if (message[i] == '3') {
+ return 3; /* release */
+ }
+ if (message[i] == '4') {
+ return 4; /* ignored + release */
+ }
+ if (message[i] == '5') {
+ return 5; /* dropped + release */
+ }
+ }
+ }
+ return 0; /* allow to transfer */
+ }
+
+Les modules doivent être compilés avec les options '-fPIC -shared'.

+5. EXEMPLES
+===========
+
+ 5.1 tcp mode
+ ------------
+
+ local network |FireWall| Internet
+ ||
+ || User 1
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || | \(tcp)
+ /(tcp) || (tcp)| User 2
+ / || \
+ Http server || User 3
+ ||
+
+
+L'utilisation de Af est extrèmement simple. Supposons que nous voulons mettre en
+place un serveur http sur notre station et que nous sommes masqueradés ou placé
+derrière un firewall:
+
+1) Nous devons tout d'abord trouver une station sur internet avec une IP
+publique et un shell.
+
+2) Utilisez ensuite make pour compiler Af sur cette machine. (Vous pouvez par la
+suite supprimer les fichiers afclient et client.rsa)
+
+3) Editez le fichier de configuration ou entrez sur la console: (pour utiliser
+la configuration, entrez type -f <cfgfile>)
+ $ ./afserver
+ Si vous voulez utiliser les valeurs par défaut:
+ - Le nom d'hôte sera pris en compte par la fonction hostname (Il serait idéal
+ qu'il soit référencé dans le fichier /etc/hosts)
+ - Le serveur sera en écoute pour les utilisateurs sur le port 50127
+ - Le serveur sera en écoute pour le client sur le port 50126
+ - Le serveur sera limité à 5 utilisateurs
+ - Le serveur retransmettra les paquets tcp
+ - Aucun log ou message verbeux ne sera activé
+
+4) Nous utilisons make sur notre propre station (Nous pouvons ensuite supprimer
+tous les fichiers sauf afclient et client.rsa)
+
+5) Nous entrons sur la console:
+ $ ./afclient -n <name of the server> -p 80
+ Où <name of the server> est une chaîne du type : 'bastion.univ.gda.pl' ou
+ '153.19.7.200'
+
+6) Nous pouvons ensuite utiliser notre navigateur web avec :
+ <name of the server>:50127 et nous atteindrons notre propre station.
+
+ 5.2 reverse udp mode
+ --------------------
+
+ local network |FireWall| Internet
+ || (udp)
+ || User 1-------AF Client
+ || /(tcp)
+ AF Client <---Encrypted/Compressed channel---> AF Server
+ / || |
+ /(udp) || (tcp)|
+ / || /
+ Game server || AF Client-------User 2
+ || (udp)
+
+
+Regardons comment nous pouvons utiliser af pour forwarder des paquets udp.
+Supposez que nous voulons mettre en place un serveur de jeu sur notre station
+(port udp 27960 sur notre station):
+
+1) - 4) sont les mêmes que pour l'exemple 1.
+
+5) Nous entrons sur la console:
+ $ ./afclient -u -n <name of the server> -p 27960
+ Où <name of the server> est un nom (ou une ip) d'un hôte sur lequel notre
+ serveur tourne.
+
+6) Nous connecter à notre jeu est un peu plus compliqué. L'utilisateur doit se
+ servir de afclient pour cela.
+ Il doit spécifier le serveur auquel il veut se connecter et le port sur
+ lequel son programme sera en écoute:
+ $ ./afclient -U -d <hostname> -p <portnum> -n <name of the server> -m\
+ <server port>
+ Où <hostname> est le nom de la station utilisateur (qui veut se connecter à
+ notre jeu). <portnum> est le port auquel il se connectera. <name of the
+ server> est le nom de l'hôte sur lequel notre serveur tourne. <server port>
+ est le port sur lequel notre serveur est en écoute pour les utilisateurs.
+ Pour se connecter à notre jeu, l'utilisateur doit se connecter à <hostname>:
+ <portnum>.
