[CentOS] FreeNX authenticates but no desktop on centos 5 ??
Hi all, I am new to CentOS and freeNX -- both look really awesome, a huge thanks to all the people making them happen. I am having a problem with freenx that appears to be specific to centos 5. my client authenticates but then no desktop comes up. however, when I connect to a similar machine running centos 4.4, I authenticate and the gnome desktop just pops up sweet as can be. I also have a vnc connection to my centos 5 workstation working, and can get a gnome desktop through vnc, and direct X11 connections are fine. the two nxserver machines have stable IP addresses, I have root access. the nxclient machine is a mac G4 PPC (which presumably makes no difference at all), with very recent download of the mac OS X client from nomachine. I followed the instructions for setting up freenx on centos 4.4 found here: http://linuxgazette.net/135/knaggs.html and it worked perfectly the first time I tried. the key steps were wget http://mirror.centos.org/centos/4/extras/i386/RPMS/nx-1.5.0-1.centos4.i386.rpm wget http://mirror.centos.org/centos/4/extras/i386/RPMS/freenx-0.5.0-10.c4.noarch.rpm sudo rpm -Uvh nx-1.5.0-1.centos4.i386.rpm sudo rpm -Uvh freenx-0.5.0-10.c4.noarch.rpm plus a quick copy-paste of the client dsa key, and nxserver --adduser <me> For CentOS 5, I tried the yum-based instructions found at http://wiki.centos.org/FreeNX (which says that freenx only works with centos 4, and the bottom of page says "FreeNX (last edited 2007-02-08 23:38:36 by JohnnyHughes )" -- hopefully its just the wiki is out of date) I also tried adapting the above steps to use the centos 5 packages from http://mirror.centos.org/centos/5/extras/i386/RPMS/ freenx-0.5.0-13.el5.centos.i386.rpm 08-Apr-2007 11:00 66K nx-2.1.0-6.el5.centos.i386.rpm 08-Apr-2007 11:00 2.9M either way, I get authenticated but no desktop comes up in the X11 window on the client machine. (just to be explicit: using exactly the same client I do get a desktop on the centos 4.4 machine). While trying to connect, During this time, on the remote (CentOS) machine, its clear that something is happening, because "ps -ef | grep nx" on the server machine gives me root 5627 3378 0 10:38 ? 00:00:00 sshd: nx [priv] nx 5629 5627 0 10:38 ? 00:00:00 sshd: nx at notty nx 5630 5629 0 10:38 ? 00:00:00 /bin/bash /usr/bin/nxserver -c /usr/bin/nxserver nx 5771 5630 0 10:38 ? 00:00:00 sleep 60 jg 5800 5393 0 10:38 pts/1 00:00:00 grep nx I checked out a couple other things on the web on how to set it up and these did not help (they were very helpful, just not with my problem about the desktop not coming up). E.g., http://fedoranews.org/contributors/rick_stout/freenx/ I also noted other posts about freenx on this list, but they did not seem to be relevant However, I note that at http://wiki.centos.org/FreeNX is says that freenx only works with centos 4, which I am hoping is simply out of date, as freenx is shipped as part of centos 5. I saw a post today saying that freenx is supposed to work exactly the same on CentOS 5 as per instructions for 4. hmmm. I've tried uninstalling freenx on the centOS 5 machine and reinstalling. any suggestions appreciated! many thanks, --Jeremy -------------- next part -------------- An HTML attachment was scrubbed...

I followed the instructions at http://wiki.centos.org/FreeNX and all is fine on CentOS 5. All I did on the server mchine was to 'run yum install nx freenx' and nothing else. It creates user "nx" on the server. For the client, again, I followed the procedure exactly as shown on the wiki page, nothing extra. Akemi

I just setup nx and freenx on CentOS 5 last night so I could get into Xen to adjust a Windows server.> the two nxserver machines have stable IP addresses, I have > root access. the nxclient machine is a mac G4 PPC (which > presumably makes no difference at all), with very recent > download of the mac OS X client from nomachine.What is the version number of nxclient that the mac G4 have installed?> I followed the instructions for setting up freenx on centos > 4.4 found here:http://linuxgazette.net/135/knaggs.htmlfreenx-0.5.0-13.el5.centos> and it worked perfectly the first time I tried. the key steps were > > wget > http://mirror.centos.org/centos/4/extras/i386/RPMS/nx-1.5.0-1. > centos4.i386.rpm > wget > http://mirror.centos.org/centos/4/extras/i386/RPMS/freenx-0.5. > 0-10.c4.noarch.rpm > <http://mirror.centos.org/centos/4/extras/i386/RPMS/freenx-0.5 > .0-10.c4.noarch.rpm> > sudo rpm -Uvh nx-1.5.0-1.centos4.i386.rpm > sudo rpm -Uvh freenx-0.5.0-10.c4.noarch.rpm > > plus a quick copy-paste of the client dsa key, and nxserver > --adduser <me> > > For CentOS 5, I tried the yum-based instructions found at > http://wiki.centos.org/FreeNX (which says that freenx only > works with centos 4, and the bottom of page says "FreeNX > (last edited 2007-02-08 23:38:36 by JohnnyHughes )" -- > hopefully its just the wiki is out of date)Wrong and out of date. I simply did a 'yum install nx freenx'. Once it finished I coppied the /etc/nxserver/client.id_dsa.key (from the server) to my (client) system, and renamed it to the hostname.id_dsa.key for tracking. Obviously imported it into the nxclient as the key to use with ssl encryption enabled. Then connected. Took me about 2 minutes to finish short of downloading the latest linux client for my workstation. The install is intelligent and restarts ssh for you, and works out of the box. I also installed this server with ONLY the Server X Windows option, disabling the Gnome and any other desktop (not sure if server just enabled gnome after the fact), but when I setup nxclient, I told it to open Gnome, and I still got a desktop. Of course I was logging in as root at the time, so I skipped the adding the user step, but I often do for testing initially to ensure its working. But obviously your user steps should apply for accounts other then root.> I also tried adapting the above steps to use the centos 5 > packages from http://mirror.centos.org/centos/5/extras/i386/RPMS/ > freenx-0.5.0-13.el5.centos.i386.rpm 08-Apr-2007 > 11:00 66K > nx-2.1.0-6.el5.centos.i386.rpm 08-Apr-2007 > 11:00 2.9M > > either way, I get authenticated but no desktop comes up in > the X11 window on the client machine.

Have you tried logging into root or other users? If you havent taken the exact steps I did, remove the other components, just yum install like I did, and recopy the client.id_dsa.key. If the system isnt in production and you can restart it then do after you uninstall. Hate to suggest a windowism, but just to make sure the X server on the local box is restarted if its running, and ssh is flushed before it reloads the NX configuration again and restarts (which you should see during the yum installations).> any suggestions appreciated! many thanks, > > --Jeremy > >
