HOWTO: Install freenx

No. It was libXcomposite. I'm pretty sure because I copied it. Unfortunately I don't have the error anymore or is there a log or something I can find it?

No need anymore, net-misc/nx now depends on libXcomposite (another round of compilation showed up the missing depend at link).

The ebuild should really be OK now, as it passed our nice x86 team tests for stabilization

Also, I'll soon start to write some Gentoo documentation on NX/freenx and friends, if you think some subjects other than the following should be treated, please tell me. Current plan is:

what is NX (technology, licensing, ...)
the different servers and clients (pros/cons)
specific configuration and commands by server (configuration files, where are logs, ...)
some troubleshooting tips
and of course a selection of links for further reading

I have some trouble with installing nxserver on my gentoo (uptodate)

My package.keywords

I just switched from X11-forwarding over ssh to FreeNX and must say, so far I am happy with its bandwidth consumption, or lack thereof. Anyway, there were a couple of features of X11-forwarding that I loved that I am wondering if I can get to work with FreeNX. I am forwarding a full WM environment (fluxbox) and using virtual desktop mode.

1. When forwarding a WM over ssh, the WM picks up local windows as well (existing and new) so that I could do thinks like play video locally or run a local terminal as if everything was running on a single desktop on a single machine. I have tried to accomplish this with FreeNX (both in virtual desktop mode and in floating window mode) without success. For the terminals etc. I can do ssh forwarding back to the client, but this wouldnt' be possible with things like video. Does FreeNX have this functionality?

2. I use xscreensaver to local the local client X session as locking the remote session would be a waste of bandwidth and a drop in security. However, when I try to lock the local x session under freenx, nothing happens. It is as if xscreensaver is running beneath the freenx window (I'm running at fullscreen).

3. I have noticed that some applications, conky for example, use a lot of CPU when running over FreeNX. I think that this is because neither graphics cad is being utilized and everything is being rendered by the host CPU. Granted, I have not setup X on the host since it is a headless box, but is it possible to utilize it's graphics card at all (or even the clients)?

Thanks.

Voyageur, I did try running the WM as a floating window, but didn't get very far. I did notice the following though, 1) it did not pick up existing local windows, 2) I did not have access to the full screen. That is to say, when I moved outside of the WM's windows, it was as if I was back on the local machine without a WM and I couldn't access the background (meaning I couldn't run the menu for fluxbox). I don't know if that's clear. I'll try again later today.

I've been running nxserver-freenx for years without problems

, but now I want to include nxclient on my gentoo system. The problem is that when I add in USE=nxclient I get into a seemingly unresolvable block

To handle blocked packages, the best way is usually to remove the old package and then emerge the new package (in this case nxserver-freenx)

The blocker is here because switching the nxclient USE flag would cause file collisions on nxclient between nxclient and freenx

Bad choice of words then, I meant "new" as in "newly emerged", not "new version compared to the current one"

Your "old" nxserver-freenx (with USE=-nxclient) owns the file /usr/bin/nxclient. Emerging freenx with USE=nxclient will pull in net-misc/nxclient, which would also install /usr/bin/nxclient. Removing the old nxserver-freenx would remove this file, and you would end up with net-misc/nxclient installed, but no nxclient binary anymore

Hmm, I hope I did not confuse you even more

But in short:

Hey all.
Another question.

Is it possible to resume a session from a different ip than the one from which it was suspended?
I'm trying to open the session from my remote machine when I'm at home, and I see the session listed in the console, but it says status is not available and it won't let me resume. I've searched through the server configs and found nothing.

Thanks.

EDIT: Fixed, sort of. It seems like the problem only occurs between windows and linux sessions. For me, it was started on a linux session and I couldn't resume it from windows.

Just recently I updated pam to: sys-libs/pam-0.99.8.1-r1

After a couple of package rebuilds because of their dependency on pam (ie. openssh) I restarted my system completely to make sure everything was working.

I am able to login locally and remotely with SSH (openldap authentication on the backend), but now when I try to use NXclient to connect I receive the following:

I installed freenx and it works great with the client, but...

If I choose a resolution smaller than 1280x1024, I use at home, I get everything fine except of the desktop itself. I can only see shortcuts I place in the upper left corner and the background image is not completely displayed.

Conky runs well in the upper right corner, though. The panels and all the other stuff is running in the smaller resolution as well.

This is not a big deal, I could place all shortcuts in the upper left corner, but I want to know if this is a configuration problem?

In my xorg.conf are the following settings (I have other resolutions):

How are things going with the new nx 3 features? I really would like to get my hands on that shadowing.

Freenx redesign is under way, but don't expect it too soon

The wiki page on it is here. There is some kind of session shadowing in freenx 0.7.1 (via vnc), which I'll probably add tonight though

lorenct, at this point it is normal that you do not get any log from nxserver, as it has not started yet. If you still have the problem, increase the verbosity of sshd and look through its log

I haven't tried much yet and actually I just use it to have a fast and secure x terminal to my machine at home. For my need it works good and very fast.

Recently I changed from Gnome to Xfce4.

Xfce isn't supported by the windows client, you can define a commandline to start the proper windowmanager (startxfce4). It comes up with the complete desktop in 1024x768, using xfdesktop (better than nautilus).

The X session isn't closing, even though I logout properly. The administration tool comes up with a paused session.
If I choose terminate, it only happens clientside.

Via ssh (Putty) I can see that the server is still running with everything like xscreensaver, conky etc. The next session it will start everything again and creates new zombies.

With Gnome I had no problems, except of that the background and desktop wasn't completely displayed (using Nautilus).

Looks like LDAP is causing me grief.

I had another system not tied into using LDAP authentication for users and nxserver works fine with the latest stable release of PAM. (sys-libs/pam-0.99.8.1-r1)

My /etc/pam.d/system-auth file:

Looks like the issue was with my /etc/pam.d/system-auth file.
