[FreeNX-kNX] FreeNX-kNX Digest, Vol 34, Issue 2

Mon Jun 4 12:28:19 UTC 2007

Thanks for your help.

yes I still have the following in the session log  /usr/libexec/nx/nxnode: line 306: startkde: command not found

when I type- find / -iname startkde it takes 5 minutes but nothing is found.

when I type- which startkde I get the following-
/usr/bin/which: no startkde in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/                                             sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/NX/bin:/root/bin)

I have pasted in below the node.conf from /etc/nxserver/
Sorry this is like chinese to me.

# 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/

#

# Other sources of information are the NoMachine mailing lists 

# (nxusers at nomachine.com and nxdevelopers at nomachine.com):

#########################################################################

# General FreeNX directives

#########################################################################

# The host name which is used by NX server. It's should be used if it's

# different than the default hostname (as returned by `hostname`)

#SERVER_NAME="$(hostname)"

# The port number where local 'sshd' is listening.

#SSHD_PORT=22

#########################################################################

# Authentication / Security directives

#########################################################################

# Authentication directives

# 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

#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"

#########################################################################

# Restriction directives

#########################################################################

# The base display number from which sessions are started.

#DISPLAY_BASE=1000

# The maximum number of contemporary sessions that can be run on FreeNX

#SESSION_LIMIT=200

# The maximum number of contemporary sessions that a single user can run

# on FreeNX. Defaults to the value of SESSION_LIMIT.

#SESSION_USER_LIMIT=200

# The number of displays reserved for sessions, it has to be greater or equal

# to the maximum number of contemporary sessions that a server can run.

#DISPLAY_LIMIT=200

# User for which sessions should be persistent. Either the keyword "all" or a

# comma-separated list of usernames or groups in the @groupname syntax.

#ENABLE_PERSISTENT_SESSION="all"

# Users and groups for whom persistent sessions should be disabled.

# Especially useful if ENABLE_PERSISTENT_SESSION="all"

#DISABLE_PERSISTENT_SESSION=""

#########################################################################

# Logging directives

#########################################################################

# This directives controls the verbosity of the server-wide log.

# 0: No Logging

# 1: Errors

# 2: Warnings

# 3: Important information

# 4: Server - Client communication

# 5: Information

# 6: Debugging information

# 7: stderror of some applications

#NX_LOG_LEVEL=0

# By setting this to 0 the nxserver might be a bit faster, but passwords can be found in the log files.

#NX_LOG_SECURE=1

# Before turning logging on, please make sure that NX_LOGFILE is

# writeable for the "nx" user

#NX_LOGFILE=/var/log/nxserver.log

# This directive controls if the temporary session directory

# ($HOME/.nx/C-<hostname>-<display>-<session_id>) should be kept after a

# session has ended. A successfully terminated session will be saved as

# T-C-<hostname>-<display>-<session_id> while a failed session will be saved

# as F-C-<hostname>-<display>-<session_id>.

# The default is to cleanup the directories.

#SESSION_LOG_CLEAN=1

# Amount of seconds nxserver is to keep session history. The default of 2592000

# is equivalent to 30 days. If this is 0 no session history will be kept

# and a negative value denotes infinity.

#SESSION_HISTORY=2592000

#########################################################################

# Forwarding directives

#########################################################################

# FreeNX with ENABLE_SERVER_FORWARD="1" will automatically forward all

# connections to the host specified in SERVER_FORWARD_HOST with the

# secret key SERVER_FORWARD_KEY.

#

# This allows to have a "chain" of NX Servers. Note that you will need to

# use "SSL encryption" for all connections.

#ENABLE_SERVER_FORWARD="0"

#SERVER_FORWARD_HOST=""

#SERVER_FORWARD_PORT=22

#SERVER_FORWARD_KEY="/usr/NX/share/client.id_dsa.key"

# FreeNX with ENABLE_NOMACHINE_FORWARD_PORT="1" will automatically forward all

# connections to the commercial NoMachine nxserver installed on the same

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

# to enable the usage of FreeNX and NoMachine NX side by side on the same machine

# without conflicts.

#

# Note: You need to let SSHD listen to several ports to make use of this

# directive.

#ENABLE_NOMACHINE_FORWARD_PORT="0"

#NOMACHINE_FORWARD_PORT="22"

#NOMACHINE_SERVER="/usr/NX/bin/nxserver"

#NOMACHINE_NX_HOME_DIR="/usr/NX/home/nx"

# 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"

#

#LOAD_BALANCE_ALGORITHM="load"

# 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.

#ENABLE_LOAD_BALANCE_PREFERENCE="0"

#########################################################################

# Services directives

#########################################################################

# FreeNX with ENABLE_ESD_PRELOAD="1" will automatically try to setup

# the sound with the help of the esd media helper.

# before enabling this directive.

#ENABLE_ARTSD_PRELOAD="0"

#ARTSD_BIN_PRELOAD="artsdsp"

# FreeNX with ENABLE_KDE_CUPS="1" will automatically write 

# $KDE_PRINTRC and put the current used port into it.

# $KDE_PRINTRC is automatically calculated if its not set.
