#1

hello.

Opensuse 11.3

here is my configuration files :

/etc/sysconfig/apache2 :
APACHE_CONF_INCLUDE_FILES="/etc/apache2/httpd.conf.local"

Note : Doing this way ( recommanded by apache documentation ) I don’t know if it is the good way as recommended by NOMACHINE documentation : <<It can be updated by adding the following directive before the “Global Environment” section >>

/etc/apache2/httpd.conf.local
Include /usr/NX/etc/manager.conf

/usr/NX/etc/manager.conf :
Alias /nxmanager/ “/usr/NX/share/htdocs/nxmanager/”
ScriptAlias “/nxmanager” “/usr/NX/bin/nxmanager”
<Directory “/usr/NX/”>
AllowOverride None
Options None
Order allow,deny

ADDRESS RESTRICTIONS START

Allow from all

ADDRESS RESTRICTIONS STOP

</Directory>

/usr/NX/etc/manager.cfg ( just the modify part :

Specify user name of Apache owner.

#ApacheUname = “nobody”
ApacheUname = “wwwuser”

Specify group name of Apache owner.

#ApacheGname = “nogroup”
ApacheGname = “wwwgroup”

Hello.

Partially solved by re-running nxmanager --update.

But know can’t log with success in the nxmanager login screen : password error.
But there no defined password ( and no passwdDB at all ) as I use SSHD authentication with PAM enabled.

Both ‘EnableUserDB’ and ‘EnablePasswordDB’ are set to 0, so any user are being authenticated by SSHD account and then will be enabled to connect to the system.

So How to connect to nxmanager ?

usually nxserver and the rest of the bits needs to own or have access to those directories. They are usually owned by user nx or root. For example /usr/NX/var/db/ is nx:root It definitely seems to be wrong permissions somewhere. I’ve been using NX on openSUSE for years and never had issues.

Hello.

OK I will look after that and give you news.

Thank you for your time.

NOTE : All the commands are executed from my laptop on the server using an NX session using the root user as I manage the server from the laptop. The server have no screen and no keyboard. Using a normal user even with su can’t stop the server.

Have change owner
chown -R nx:root /usr/NX

have update nxmanager ( mandatory ; if not it does not work )
nxmanager --update

Ok now I get the login screen and I can log.

Thank you very much for your help.
