 ##
 # Shell script to start R server (for StatET)
 ##
 # Usually you have to change only the CONFIG sections. You should set at least:
 #     R_HOME
 #     JAVA_HOME
 # Depending on the system configuration, it can be required to set:
 #     S_HOSTADDRESS
 #
 # The authentication is set to 'fx' (method using SSH) by default.
 ##
 # Usage of this script:
 #     startup.sh <address> [options]
 #     startup.sh <name> [options]
 # It starts the R server asynchronously in background by default.
 #     <address>                        the complete RMI-address
 #     <name>                           the session name only (the hostname
 #                                      should be set in this file)
 # Options:
 #     -wd=<working directory>          initial R working directory
 #     -debug                           enables debug output and
 #                                      runs R in foreground
 #
 # Note: This script does not start an RMI registry! You have to launch it
 # as system daemon or manually (see Java documentation), e.g. by:
 #     $JAVA_HOME/bin/rmiregistry -J-Djava.rmi.server.codebase=file:///<path to file org.eclipse.statet.rj.server.jar> &
 # or if appropriate by uncommenting the section "Start registry" in this script.

 # Configure the startup in the following sections

 ###############################################################################
 # Required system specific settings
 #
 # Set the path to home of R and Java.
 # If parts of the R installation (e.g. the documentation) are located in not
 # sub-directories of R home, it is often required to set additional variables
 # specifying the several installation locations (see example).
 #
 # Example:
 #     R_HOME="/usr/lib/R"
 #     R_ARCH="/x64"
 #     R_DOC_DIR="/usr/share/doc/R"
 #     R_SHARE_DIR="/usr/share/R"
 #     R_INCLUDE_DIR="/usr/include/R"
 #     R_LIBS_SITE="/usr/local/lib/R/site-library"
 #     JAVA_HOME="/usr/lib/jvm/java-11-openjdk"

 R_HOME=
 JAVA_HOME=

 ###############################################################################
 # Set the home and work directory of this R server.
 # The home must contain the jar files of this server, if this file is in this
 # directory, you don't have to change the value.
 # The working directory is for files like log files
 ##
 # Example:
 #     RJS_HOME=`dirname "$SCRIPT"`
 #     RJS_WORK="$HOME/R/rjserver/work"

 RJS_HOME=`dirname "$SCRIPT"`
 RJS_WORK="$HOME/R/rjserver/work"

 ###############################################################################
 # Set explicitly the hostname and port you want to use to access the RMI
 # registry/R server.
 # It is recommended to use the IP address instead of a name.
 # By default, the hostname is extracted form the specified RMI address
 # (script parameter). Nevertheless there are some reasons to set it explicitly
 # here, e.g.:
 #  - For SSH tunnel connections '127.0.0.1' (localhost) is sufficient;
 #    recommend, if no other network connections are used; and required if the
 #    public IP address is blocked by the firewall.
 #  - To make sure that the correct IP address is set even the hostname is
 #    used in the RMI address.
 ##
 # Usage:
 #     S_HOSTADDRESS=<ip or hostname>
 #     S_REGISTRY_PORT=<port of rmi-registry>
 # Example:
 #     S_HOSTADDRESS=192.168.1.80

 # CONFIG - AUTHENTICATION METHODS #############################################
 ###############################################################################
 # You must specify the method (exactly one) to use for authentication when
 # clients wants to connect to the R.
 # There are several methods available. The methods provided by default
 # are described in the following subsections. To change the method uncomment
 # the lines of method you want to use and comment the previous AUTH definition.
 ##
 # General usage:
 #     RJ parm:     -auth=<method-id>[:<config>]
 #                  -auth=<classname>[:<config>]
 #
 # <config> option depends on the selected method

 ###############################################################################
 # Authentication method: disabled / 'none'
 #
 # Disables authentication. Anybody can connect to R. Use it only if you are in
 # a secure environment! All users can connect to R get full user rights!
 ##
 # General usage:
 #     RJ param:    -auth=none
 #
 # Script Usage:
 #     AUTH="none"

 #AUTH="none"

 ###############################################################################
 # Authentication method: password file / 'name-pass'
 #
 # Authentication using loginname-password combination.
 ##
 # General usage:
 #     RJ Param:    -auth=name-pass:file=<passwordfile>
 #
 # Script usage:
 #     AUTH="name-pass:file"
 #     AUTH_PW_FILE="$HOME/R/rjserver/logins"
 #
 # <passwordfile> is the path to a property file with
 #     pairs of loginname and password, for example:
 #         myname=mypassword
 #     Make sure that only authorized users can read this file!

 #AUTH="name-pass:file"
 #AUTH_PW_FILE="$HOME/R/rjserver/logins"

 ###############################################################################
 # Authentication method: local user account / 'local-shaj'
 #
 # Authentication using your local loginname-password combination (PAM).
 # The 'Shaj' library is required for this method. It is provided in sources and
 # binary form for several platforms. If no binary match your environment, you
 # have to build it for your system. You find the files inside the folder
 #     shaj
 # of this remotetools package.
 ##
 # General Usage:
 #     RJ Param:    -auth=local-shaj
 #     Java Prop:   java.library.path=<folder of library>
 #
 # Script Usage:
 #     AUTH="local-shaj"
 #     AUTH_SHAJ_LD_DIR="<folder of library>"
 # Example:
 #     AUTH=local-shaj
 #     AUTH_SHAJ_LD_DIR="$RJS_HOME/shaj/linux-x64"

 #AUTH="local-shaj"
 #AUTH_SHAJ_LD_DIR="$RJS_HOME/shaj/<platform>"

 ###############################################################################
 # Authentication method: ssh / 'fx' (exchange over file)
 #
 # Authentication for automatic startup (via ssh by StatET).
 ##
 # General Usage:
 #     RJ Param:    -auth=fx:file=<keyfile>
 #
 # Script Usage:
 #     AUTH="fx:file"
 #     AUTH_FX_FILE="<keyfile>"
 #     AUTH_FX_USER=$USER
 #     AUTH_FX_MASK="600"
 #
 # <keyfile> a (empty). The fs permission to edit the files represents the
 #     right to login into R, so:
 #     The file must be writable for authorized user only!
 #     If the script setup is used, the files is created automatically and
 #     the permission is set according to AUTH_FX_USER and AUTH_FX_MASK
