I think you can ignore these errors. They are caused by the 0.7.1 version of freenx. But I see there are new nxlibs and a new freenx release available. I'll try to package them... X!!

See freenx changelog: http://svn.berlios.de/svnroot/repos/fre ... /ChangeLog "Added support for 3.1.0 and later backends."

New packages:
http://thenktor.dyndns.org/packages/freenx/
http://thenktor.dyndns.org/packages/nxlibs/
http://thenktor.dyndns.org/packages/nxclient/

Note that there is a problem with expect + tcl + tk: You MUST use the versions from current because expect doesn't work with the snapshot versions of tcl/tk!

If I may, I would like to comment and ask a question. Since moving to Linux a couple of years ago I always used Samba and had problems. It would work but not always. Saw the article in the wiki about freenx and searched the forum for freenx, read every article and decided to try it. Ran across some of the same problems listed in this thread so pushed on. Had trouble getting it to authenicate on the server when I tried to log in. Finally got to the end of this thread and saw your links. Downloaded and upgraded all three items you listed. Tried logging in again and it worked. I had gotten a login once before but didn't see anything. After upgrading freenx on my desktop and then logging in from my laptop I got this big window. The question now is what do I do now. I am at this point in far over my head. I shared files with Samba but this is way different and way better. I want to thank you for your hard work and your tut's. One of the problems that I have is editing the config files. I followed the wiki and made the changes listed there but there are others that weren't mentioned. Is there something somewhere that could guide me? Yes, google is my next step

. Can I use to access my home desktop from my laptop while I travel? How do I determine what is allowed to be seen? As you can see I have lots of questions and no answers at this point.

But the one thing that I can say is that for a newbie to follow and get it to work you have done some excellent work!!

Thanks, john

I went back to the wiki article and found the links to the other sites in the upper right hand corner. Man, what a lot of info. Found the pages on NoMachine's site for configuration. Very helpful. Followed through and thought I would try it again. Real surprise - it logged in and started going through the connection and all of a sudden my desktop computer's window popped up! I had my desktop on my laptop. Things like this is what keeps me here, such a great distro and people behind it. Still haven't found about connecting over the internet but haven't had a chance to read it all yet.

Again, thanks

john

You can ignore the warnings, but your "expect" does not work. Check which expect and which tcl/tk packages you have installed:
ls /var/log/packages/expect*
ls /var/log/packages/tcl*
ls /var/log/packages/tk*

I guess you have mixed packages from current and snapshot repository.

Here is my configuration:

Quote:

bash-3.1$ ls /var/log/packages/expect*
/var/log/packages/expect-20081230-i486-54.1
bash-3.1$ ls /var/log/packages/tcl*
/var/log/packages/tcl-8.5.4-i486-54.1 /var/log/packages/tclx-8.4-i486-1
bash-3.1$ ls /var/log/packages/tk*
/var/log/packages/tk-8.5.4-i486-54.1

ok, now i get this

Code:

xdell[~]$ ls /var/log/packages/expect*
/var/log/packages/expect-20081230-i486-54.1
xdell[~]$ ls /var/log/packages/tcl*

xdell[~]$ ls /var/log/packages/tk*
/var/log/packages/tk-8.5.4-i486-54.1

then i get this output

I've got the same error now, even with newest packages built today:
http://thenktor.dyndns.org/packages/expect/
http://thenktor.dyndns.org/packages/freenx/
http://thenktor.dyndns.org/packages/nxlibs/

Perhaps a freenx bug?

I am having the /dev/fd/62 error. I looked inside that script @ line 379 and it doesn't make any sense, it seems like a random error. I am not a Zen packager and I don't assume to question how you do your packaging, but perhaps we can use the binary tar.gz packages from NoMachine

http://www.nomachine.com/download-package.php?Prod_Id=539

and edit the

Code:

/usr/NX/scripts/setup

scripts to handle Zenwalk and other Slack-based distros.

That way we can then submit the changes back to the upstream maintainers and give everyone the benefit of getting this working on Zenwalk.

Same here

Did you test the provided binary packages?
As far as I remember I've decided to use FreeNX because the original NX server has some limitations (license things).

I am not a developer and could not figure out how to quickly edit the bash script used for installation. The installer expects a major distro and barfs when it can't put Zenwalk in a category. I tried attaching it to the last post but the system would not let me because it is a script. I tar.gz'd it and now it says the attachment quota has been reached. I'll host it at my webspace for now, here.

Where are you getting the sources from?

Here's an excerpt from the license I found in the documentation of the binary distribution.

Now, isn't the FreeNX server still called 'nxserver'?

If the ZENBUILD retrieves the binary package from the site and then just patches the scripts, we technically are not redistributing, are we?

We just cannot distribute the binaries on the CD without permission.

To my knowledge we are redistributing it in that case. We are not redistributing it as long as the user downloads the software from them. Whatever he does with the software or what he's allowed to do with on his computer is another point.
But if we install the package once and create an archive it is redistribution. However that may also depend on their definition of redistribution and on the appliance of their license. It's the same with the law: Often when there's a new law, nobody knows exactly what's allowed until others are punished or not punished by a judge. But in this example I of course don't now how their license is applied. $:-\$

If we put a package in our repository, we would redistribute the software

Okay, so that's a no-go. What I think I will do is work on getting the closed-source install script working on Zenwalk and make a new wiki article on how to do it. I just wanted to try out the technology, and this silly error in the FreeNX version is really turning me off.
