HOWTO: Install freenx

mana · Posted: Tue Dec 12, 2006 12:55 pm Post subject:

net-misc/nx-x11-1.4.0-r4 is a pretty old package, maybe try a newer version of freenx? Please be sure to unmerge all remaining packages before.

The backend-string may be needed to be fixed in the scripts of you verison or you could try to add "ENABLE_1_5_0_BACKEND" in your node.conf .. if i remember the attribute correctly.

For me it is working. Even with this error.

I did not need to install a new user. Just used the normal user.

Wow, so I ended up re-doing my linuxbox yesterday and I decided to try freenx again. I followed those last three commands posted above and it just works. Awsome.

I'm reposting this post because nobody answered me, so I'm trying this thread out. I just can't solve the problem described below:

Original Post:

I can't run any tcl/tk applications in NX anymore. I'm getting this error:

imanassypov

I am trying to get nxserver running on amd64, and no matter what i try I stumble across the above error.
I unmasked the x86 version, and using the nx-x11-bin package.

has anybody resolved this?

Thx!

From what I've read, the 64-bit ebuilds aren't ready yet. The ones for this 1.5 version with the overlay are only 32-bit.

They are only x86 now since Stuart mostly worked on this platform (and had problems with amd64 too). The ebuilds had some amd64 support a few months ago (when I managed to get it working

), but there were many problems.

Here are the versions I used:
nxclient-1.5.0-r4.tbz2
nxcomp-1.5.0-r2.tbz2
nxesd-1.5.0.tbz2
nxserver-freenx-0.5.0.20060311-r1.tbz2
nxssh-1.5.0-r2.tbz2
nx-x11-bin-1.5.0.tbz2

I still have the binary packages, and a tarball of /usr/NX if you want to give a try! I switched to nx freeedition now (as I am the only one using NX, the 2 concurrent connections are enough, and it has even better performance)

As posted here, there solution to the tcl/tk color problem is adding the following to your '/etc/nxserver/node.conf' file:

Voyager,

Thanks for your offer.
-yea, i'd be interested to give 'em a shot. Up to this point, the amd64 is still not there and i get

- net-misc/nxserver-freenx-0.5.0-r1 (masked by: missing keyword)

when emerging...

Can you post the tarball on ftp somewhere?

Thx!

imanassypov, all the tarballs are on my server here:
http://cafarelli.fr/gentoo/

http://cafarelli.fr/gentoo/old-freenx.tgz is the whole /usr/NX tarball, the other nx* are binary packages created with quickpkg

If you get the matching ebuilds from gentoo CVS (as they were removed from portage a few months ago), you can try a binary emerge, or directly unpack the tarball and see what it gives

(note that I was using specific SSH keys, you will need to use or change them back to default on your install)

Good luck!

FreeNX 0.6 release is great news! I have bumped ebuilds in my overlay for the adventurous to try.

For now I have tested it on a x86 server (both with USE=-nxclient and nxclient), with a remote nxclient 2.1, so far so good, but feedback is welcome

(I have a few things to tidy up in the ebuilds before passing them on to bugzilla)

Sorry did not find any time to test your ebuild. Maybe you guys in the thread here take the lead and post feedback

Definitely a problem in the configure step for rdesktop, thanks for the feedback!

Could you try again after updating the overlay? I just added a fix for this

You're welcome, thank you for the feedback (I'll be very interested in CUPS feedback, as my printer bit the dust a few months ago). By the way are you on x86 on amd64?

With a linux client, I do not have any problem resuming a suspended session, I'll try with the windows client when possible (may be a client bug too, what is your version? Current nomachine's windows binary is 2.1.0-16).

Hi,

I saw that you added my 64 bit clean patch to the experimental branch of the NX overlay.

Has anyone tested this yet. Are there any issues?

I would really like some feedback :-)

For people who want to try these native-compilation ebuilds, the NX overlay howto has some infos on how to use it (basically add the ebuilds to your local overlay, try it, give feedback/thanks to Fabian

)

I'll test them "for real" in a week (holidays for now!), native amd64 without waiting for NX 3.0 release is great news!

I think my native 64-bit AMD overlay install is fine, and but my client fails due to a display connection problem. The log from my client is below. I can't seem to find any solutions posted about not connecting to the unix socket. (I was able to connect successfully to nomachine's test server, so it's my server setup.)

Any help???

Voyageur · Posted: Thu Mar 08, 2007 11:22 pm Post subject:

ydleiF, does `nxloadconfig --check` report any problems (apart from "Users will not be able to request a XXX session")? Can you ssh without a problem to that box? Also, can you paste the uncommented lines from /etc/ssh/sshd_config (to check the server conf)

Also what do nxclient and freenx report ? (you can change NX_LOG_LEVEL=7 in /etc/nxserver/node.conf to make the server more verbose)

EDIT: just realized you are using free edition server, let's continue on this thread. This one is for GPL FreeNX edition

Hi,

I have emerged freenx from the overlay. And the server seems to be working fine since I can connect from a Windows machine using the Windows version of nxclient. However when I try to connect from another Gentoo box the client either exits immediately after authentication or shows a black/blank screen when I select XDM.

nxload --check shows no errors
XDMCP is properly configured since I can log in remotely using XDMCP without a problem.
Connecting using the Windows nxclient works fine.

Any one any suggestions on why nxclient from Gentoo does not work? I have tried all available version.

Tnx,
Al
