ok, everyone says NX is SO much faster than VNC, and since i moved to DSL from cable VNC is unbearably slow, so any tips would be appreciated.

i have tried a 2009 and 2008.1 install and get similar errors from both.

thus far: I downloaded the client, nonode and server RPM, installed them in that order. I try and connect, EVEN from within the same network and still get connection refused, time out errors.

it APPEARS as though nxserver installed ok, although it does look like its grabbed onto the loopback, is that normal?
127.0.0.1

however wehn i try and use:
nxserver --useradd mindwave --passwd XXXXXXX

I first get:

CODE

NX> 900 Verifying public key authentication for NX user: mindwave.

which seems ok so far (?) but then after an ENTIRE screen of similar data I get:

which without being an expert is PROBABLY why i cant connect

I have READ all the PDF's and some of the FAQ's as well as a DOC I found online, and still cant figure it out.

I'd REALLY love to get this working. any and all help is appreciated.

thanks

All i did to make mine working in a 2009 install,after bannging the wall with my head,was to changes some settings in the sshd_config related to X11 forwarding,where is the settings:

AllowAgentForwarding yes
AllowTcpForwarding yes
X11Forwarding yes
X11UseLocalhost yes
PermitTunnel yes

That did the trick in my case,just uncomment out those lines and change if not equal...

Cheers.....

having never used SSH I probably sound pretty stupid.

but I did a search of all my HD's and dont have a file sshd_config.

Is this a config file that gets built by hand or should it be automatically setup by default?

Thanks

This config file is relevant to openssh-server so if you have this package installed, it will exist in /etc/ssh/sshd_config.

Nomachine nxserver works like a charm.....even more easy to setup than freenx rpms provided by mandriva in the mirrors.....so if you want to set it up very easely just install the i386 rpms(they are 3 of them) from the nomachine website and install openssh-server too if not installed yet.

All you have to do is to create a new keygen for ssh to authenticate the user....just run:

CODE

nxserver --keygen

and copy the key to the client.

CODE

nxserver --useradd username

to add a user named username in this case to the allowed users to connect to nxserver(should be a valid username in the system and must be able to login via ssh)

CODE

nxserver --restart

and off you go....should be able to start a session.

If you run nxserver and a command not found is diplayed you need to put /usr/NX/bin/ in your PATH.If you run in a konsole:

CODE

export

you will be able to see if nxserver bin dir is in your PATH if not then you need to:

CODE

PATH=$PATH:/usr/NX/bin/

Hope it helps....

Cheers....
