# node.conf
#
# This file is provided by FreeNX. It should be placed either into
# /etc/nxserver/node.conf (FreeNX style) or /usr/NX/etc/node.conf
# (NoMachine NX style).
#
# It is mostly compatible with NoMachine node.conf. The most important 
# difference is that no spaces are allowed when assigning values (eg 
# "A=value" is allowed, "A = value" is NOT).
#
# This file is sourced by bash, so you can do some fancy stuff here if you
# want to, but be aware that it is sourced 3 times per connection. If you 
# want autostart stuff, set NODE_AUTOSTART instead!
# 
#
# You surely are aware that FreeNX is based on the fantastic results that
# the hard work by NoMachine.com has achieved. NoMachine.com released the
# core NX libraries under the GPL. The installation of these libs are the
# precondition for all FreeNX scripts to work. If you are installing this
# software with the help of one of the package management tools of your
# Linux distribution, you can assume that this dependency is taken care of
# by the tool.
#
# You have questions about the inner workings of the NX technology?
#
# Then you are recommended to first check out the rich and very detailed
# NoMachine documentation and their online Knowledge Base at 
#
#           http://www.nomachine.com/kb/

# This adds the usermode to the possible authentication methods
# Usermode means that a user can start the nxserver as his shell
# and connect directly to the right server via a custom client.
#ENABLE_USERMODE_AUTHENTICATION="0"

# This adds the passdb to the possible authentication methods
# Django : 2011-12-20 
# default : ENABLE_PASSDB_AUTHENTICATION="0"
ENABLE_PASSDB_AUTHENTICATION="1"

# This adds SSH to the possible authentication methods. For it to work sshd
# must be set up at localhost accepting password authentication.
#ENABLE_SSH_AUTHENTICATION="1"

# This adds SU to the possible authentication methods. For it to work the 
# "nx" user must be in the wheel (RedHat, Fedora) or the users group (SUSE)
# and the user logging in must have a valid shell that accepts the -c
# parameter.
#ENABLE_SU_AUTHENTICATION="0"

# Require all users to be in the passdb, regardless of authentication method
#ENABLE_USER_DB="0"


# If enabled forces the user to use encryption. This will bail out
# if the user does not have encryption enabled.
#ENABLE_FORCE_ENCRYPTION="0"

# Refuse the NX client connection if SSHD does not export the
# SSH_CONNECTION and SSH_CLIENT variables in the environment
# passed to the NX server.
# 1: Will check the remote IP and will not accept the
#    connection if it can't be determined.
# 0: Will accept the connection even if the remote IP
#    is not provided.
#SSHD_CHECK_IP="0"

# If ENABLE_SLAVE_MODE="1" the user will be just logged in _once_ and the 
# communication is done via nxnode slave mode.
#
# This is useful for one time passwords or to have less traffic in utmp 
# and wtmp.
#
# Also session startup times are much faster in slave mode. This is true especially 
# if many printers or shares have to be added.
#
# For this to work the binary nxserver-helper has to be installed in 
# PATH_BIN.
#
#ENABLE_SLAVE_MODE="1"

# If ENABLE_LOG_FAILED_LOGINS="1" then failed login attempts are logged to the system

# General shadowing / mirroring notes:
#
# By default shadowing is only allowed for the same user.
#
# If nxserver finds nxshadowacl binary, it asks it, for which users

# 0: Disabled. The ctrl+alt+T key combination has to be issued
#     to get the dialog for suspending or terminating the session.

# Note: To have for example startkde run on even another core, just specify:

# COMMAND_STARTKDE="taskset -c 2 -- startkde"
#
# FreeNX runs this option like: $COMMAND_TASKSET -cp "$USE_PROCESSOR_TASKSET" $$

#USE_PROCESSOR_TASKSET=""

# If you set ENABLE_ADVANCED_SESSION_CONTROL="1" you can start a new application in an already

NX_LOGFILE=/var/log/nx/nxserver.log

# This directive controls if the temporary session directory

# session has ended. A successfully terminated session will be saved as
# T-C-<hostname>-<display>-<session_id> while a failed session will be saved

#########################################################################
# Forwarding directives
#########################################################################

# FreeNX with ENABLE_SERVER_FORWARD="1" will automatically forward all
# connections to the host specified in SERVER_FORWARD_HOST with the

# machine, which go in by port NOMACHINE_FORWARD_PORT. This feature is introduced

# LOAD BALANCING
# ==============
#
# To do load balancing setup some hosts in LOAD_BALANCE_SERVERS and
# make:
#
#   - either sure that all incoming connections are sent to the master
#     server by using forwarding directives on the "slave" servers.
#
#   - or share the session database space via NFS between the servers.
#     (not recommended at the moment as race conditions for DISPLAYs can 
#      occur)
#

#LOAD_BALANCE_SERVERS=""

# The following load_balance_algorithms are available at the moment:
#
# "load", "round-robin", "random"
#
# For "load" you need a script called nxcheckload in PATH_BIN.
# 
# A sample script, which you can change to your needs it shipped with
# FreeNX under the name nxcheckload.sample.

#LOAD_BALANCE_ALGORITHM="random"

# By setting ENABLE_LOADBALANCE="1" you can let users choose their
# preferred host, while being forwarded to another server. Of course
# this is just a preference. The loadbalancing algorithm can completely
# choose to ignore the users choice.
