guacd()                           Guacamole                          guacd()

NAME

       guacd - Guacamole proxy daemon

SYNOPSIS

       guacd [-b HOST] [-l PORT] [-p PID FILE] [-L LOG LEVEL] [-C CERTIFICATE FILE] [-K KEY FILE] [-f]

DESCRIPTION

       guacd is the Guacamole proxy daemon used by the Guacamole web application and framework. As JavaScript cannot handle binary protocols (like VNC

       and remote desktop) efficiently, a new text-based protocol was developed which would contain a common superset of  the  operations  needed  for

       efficient  remote  desktop access, but would be easy for JavaScript programs to process.  guacd is the proxy which translates between arbitrary

       protocols and the Guacamole protocol.

OPTIONS

       -b HOST

              Changes the host or address that guacd listens on.

       -l PORT

              Changes the port that guacd listens on (the default is port ).

       -p FILE

              Causes guacd to write the PID of the daemon process to the specified file. This is useful for init scripts and is used by  the  provided

              init script.

       -L LEVEL

              Sets  the  maximum  level  at  which guacd will log messages to syslog and, if running in the foreground, the console.  Legal values are

              debug, info, warning, and error.  The default value is info.

       -f     Causes guacd to run in the foreground, rather than automatically forking into the background.

SSL/TLS OPTIONS

　　　　　If libssl was present at the time guacd was compiled, it will contain SSL/TLS support, and connections between the web application and guacd
　　　　　can be encrypted if a certificate file is given.

　　　　　When using a chain of certificates, you must append the additional certificates to your server certificate. This can be done easily with the
　　　　　standard cat command. Beware that the certificate for guacd must be the first certificate in the file.

　　　　　-C CERTIFICATE FILE
　　　　　Enables SSL/TLS using the given cerficiate file. Future connections to this instance of guacd will require SSL/TLS enabled in the client
　　　　 (the web application). If this option is not given, communication with guacd must be unencrypted.

　　　　　-K KEY FILE
　　　　　Enables SSL/TLS using the given private key file. Future connections to this instance of guacd will require SSL/TLS enabled in the
　　　　　client (the web application). If this option is not given, communication with guacd must be unencrypted.

NAME

       /etc/guacamole/guacd.conf - Configuration file for guacd

DESCRIPTION

       /etc/guacamole/guacd.conf  is the configuration file for the Guacamole proxy daemon used by the Guacamole web application and framework, guacd.

       Use of this file is entirely optional, and all of its options can be specified from the command line when running guacd.  If you  provide  both

       the guacd.conf file and command line options, the command line options will take precedence.

SYNTAX

       guacd.conf  is  made  up  of sections, where each section contains a set of parameter/value pairs. The parameters available are dictated by the

       section in use, and parameters may only be specified within a section.

       The beginning of each section is denoted with a section name in brackets, and each section ends implicitly with the beginning of a new section,

       or at the end of the file.

       [server]

              Contains parameters which control how guacd behaves as a server, from a network perspective.

       [daemon]

              Parameters which configure how guacd behaves as a daemon, such as what file should contain the PID, if any.

       [ssl]  Parameters  which  control the SSL support of guacd, such as the certificate and private key used for encryption of the Guacamole proto-

              col. This section and its parameters are only valid if guacd was built with SSL support.

       Parameters within sections are written as a parameter name, followed by an equals sign, followed by the parameter value, all on one line.  Com-

       ments may be placed anywhere, and consist of arbitrary text following a # symbol until end-of-line:

       name = value # Some arbitrary comment text

       Beware  that  it  is  the  combination  of the section name with the parameter name that makes up the fully qualified name of a parameter. Each

       parameter absolutely must be placed only within its proper section, or guacd.conf will fail to be parsed, and guacd will not start.

　　　　　If special characters need to be placed within a parameter value, such as whitespace, #, ", or \, the entire value must be enclosed in double
　　　　　quotes, and each occurrence of " or \ within the value must be escaped with backslashes:

　　　　　name = "quoted # value \\ with \" special characters"

SERVER PARAMETERS
　　　　　bind_host = HOSTNAME
　　　　　Requires guacd to bind to a specific host when listening for connections. By default, guacd will bind to localhost only.

　　　　　bind_port = PORT
　　　　　Requires guacd to bind to a specific port when listening for connections. By default, guacd will bind to port 4822.

DAEMON PARAMETERS
　　　　　log_level = LEVEL
　　　　　Sets the maximum level at which guacd will log messages to syslog and, if running in the foreground, the console. Legal values are
　　　　　debug, info, warning, and error. The default value is info.

　　　　　pid_file = FILE
　　　　　Causes guacd to write its PID to the specified file upon startup. Note that guacd must have sufficient privileges to create or write
　　　　　this file, or it will fail to start. This parameter is typically needed for startup scripts, such that the script can report on the sta-
　　　　　tus of guacd and kill it if necessary.

SSL PARAMETERS
　　　　　If guacd was built with SSL support, then connections between the web application and guacd can be encrypted if an SSL certificate and key file
　　　　　are given.

　　　　　When using a chain of certificates, you must append the additional certificates to your server certificate. This can be done easily with the
　　　　　standard cat command. Beware that the certificate for guacd must be the first certificate in the file.

　　　　　server_certificate = CERTIFICATE FILE
　　　　　　　Enables SSL/TLS using the given cerficiate file. Future connections to guacd will require SSL/TLS enabled in the client (the web appli-
cation).

　　　　　server_key = KEY FILE
　　　　　　　Enables SSL/TLS using the given private key file. Future connections to guacd will require SSL/TLS enabled in the client (the web appli-
cation).

EXAMPLE
　　　　　#
　　　　　# guacd.conf example

　　　　　[daemon]

　　　　　pid_file = /var/run/guacd.pid

　　　　　[server]

　　　　　bind_host = localhost
　　　　　bind_port = 4822

　　　　　[ssl]

　　　　　server_certificate = /etc/ssl/certs/guacd.crt
　　　　　server_key = /etc/ssl/private/guacd.key
