Red Hat / Fedora :: RHEL 5.4 With FreeNX - Timeout

Nov 15, 2010

I have successfully setup FreeNX on Suse 10.2, Suse 11 (32 and 64 bit), and am now attempting on RHEL 5.4 (32 and 64 bit). For both distributions, the client fails to times out at exactly the same point - downloading the session information. Here are the steps I took to install/configure.

Debian Configuration :: Run Remote Desktop Sessions - FreeNX Connection Timeout

Apr 19, 2010

I have a Debian VPS running Lenny and I'm trying to setup a way to run remote desktop sessions from it. I went with FreeNX, NX client for windows from nomachine, XDM and xfce4. All seems to have installed well, but I can't start an NX session on my box. I can connect to the server and authenticate, but the client hangs on "Downloading the session information," eventually timing out. The log output is below - I'm not even seeing an error message. Any ideas?


The only thing I noticed during install, which was about 400 packages since this was a barebones VPS, was that I should consider recompiling the kernel with CONFIG_SOFTWARE_SUSPEND=y. I don't know if this has any impact on session information, however, since this is a new session, not one I'm trying to resume.

Server :: RHEL 4 Grub Timeout Not Working?

Mar 29, 2010

I have an RHEL 4 server now running 2.6.9-89.0.18. After installing the kernel and rebooting to make this the current kernel, the grub menu to choose the kernel failed to offer a countdown and did not choose the kernel as it should have. I had to manually select the kernel.I inspected the grub.conf file and could not find any clue as to why it didn't work. The timeout directive is there, and the syntax matches other systems we have with the same kernel and OS.Can anyone provide any insight as to what else (other than a typo on the conf file) would cause this?The only difference between the way the kernel update (and the subsequent changes to the grub conf file) took place was a manual install of the RPM on the affected system, versus pulling it down from RHN using up2date.

Software :: Nomachine On RHEL 4/5 - Timeout In Session Download

Jan 4, 2010

I've installed the latest no machine rpms from nomachine. Status shows that nx server is running:


However, connecting from a windows client, I get the following:


So I get past authentication, but it then times out during session download. And here's the output from /var/log/messages on the server:


The only strange thing I've noticed (other than the error messages) is that the log messages for NXServer/NXnode have a date of Jan 5, yet the correct system time should be Jan 4 as seen in the first message.

Note this is happening on both my RHEL 4 and RHEL 5 machines.

Fedora :: FreeNX Server Performance Under Fedora 14 - Disable OpenGL?

Nov 27, 2010

I'm noticing that the performance for FreeNX Server under Fedora Core 14 is really bad. The screen refreshing is painfully slow. I'm thinking maybe the issue is related to the use of opengl in the X driver? how I can disable opengl entirely, so that the X server is only using 2d rendering?

Fedora :: Beesu Through NX Does Not Retain Password Timeout

Dec 1, 2009

I use NX Server 3.4.0-8 and GNOME desktop and I connect through NXClient 3.4.0-5 on Windows 7 pro 64bit.

I have some problems, first is that I use beesu and through the physical console, it asks me once for my password and then remembers it as long as the passwd timeout is set on sudoers file. But when I connect to my desktop through NX, beesu asks for mypassword all the time not honoring the save timeout setting.

Fedora :: VNC Server - Get Timeout Or Connection Refused

Jan 30, 2011

I have a box running Fedora 14 upstairs and I've been trying to get it to run VNC server, unsuccessfully. I've RTFM, and followed the instructions step-by-step, but it still won't run. I'm getting no error messages. But when I try to connect from either a Window or Mac client, it either get a timeout or connection refused. I've read and tried all the troubleshooting; been working on this for about 12 hours now. Is there something major that I could be overlooking?

Fedora :: F15 And Evolution Message Read Timeout

Jun 9, 2011

I installed fresh installation of F15 and I've allways used Evolution as my mailclient. There was in older Evolution versions option "Mark message as read in X secs" I set that to zero to read emails smoothly, now I have to wait after every message that it's got "as read" and that's really annoying especially if it's automatically sent message from server that I don't really have to "check" it just click it to get it as read. I've been gone thru all the settings of current Evolution in F15 and haven't found anymore that option. Maybe there's conf file somewhere that I can put that? That "Help" page for Evolution is kinda outdated.

Fedora :: Nm-applet Timeout - Restore The Connection Indefinitely

Sep 15, 2010

nm-applet timeout. I connect to the internet via wifi access. I have this problem that whenever there is a powercut, my wifi router switches off and then nm-applet tries to connect and then after sometime times out i.e. nm-applet gives up on trying to restore the connection.

I want nm-applet to keep trying to restore the connection indefinitely because if the electricity is back lets say after an hour then it should immediately connect without manual intervention.

I did google around trying to search for the configuration parameters but was not able to do so.

Fedora :: Ssh Timeout - Returns Deatils Of Two Adapters - 'lo' And 'p2pl'

Jun 15, 2011

I am very new to this and seem to have fallen at the first hurdle configuring ssh...

I believe I have got ssh running (on Fedora 15) as running:

results in a password prompt and successful login

Then to find my ipaddress i ran:

this returns deatils of two adapters... 'lo' and 'p2pl'. I assumed p2pl was the one (although was expecting something like eth0) and took the address to be 'inet addr:'.

However, using this from putty on my windows7 machine (locally) results in a fatal network timeout everytime.

CentOS 5 :: Pirut/yum: RHEL 5.1 - Maintain An Unregistered RHEL Box?

Feb 16, 2010

A client has sent me an RHEL 5.1 box for me to do some work on, but it's not registered with Red Hat. This is causing me problems, because it's a minimal installation, and I need some more dev software.My immediate reaction was to install various bits (emacs, and so on) from my Centos 5(.0) DVD.The base RHEL system only had one (disabled) repo entry,so I added a yum DVD repo entry in yum.conf.d.

This looked good to start with, but it doesn't work. Something in RHEL's pirut/yum/rpm/whatever is getting confused, and can't work out what is/isn't installed.

Question - how do you maintain an unregistered RHEL box? Has RH done something to make life difficult? Is my problem simply that I'm using a Centos 5.0 DVD, instead of Centos 5.1? Am I stuck with downloading lots of rpms from the net and doing everything manually? I really don't want to do that.

OpenSUSE :: Freenx Fails In 11.2 / Fix It?

May 3, 2010

I'm having some trouble with FreeNX on OpenSuse 11.2. I followed the instructions on this page to set up the server on my linux machine, and I'm connecting to it with the Nomachine client for Windows, running on Windows XP x64. It refuses to complete the connection, and the console log from the NX client is as follows code...

I've searched this forum and many web pages on google, but I haven't found anyone with this exact problem. the fact that it can't stat those files suggests to me that it might be a permissions thing, but I wouldn't expect non-root users to EVER have permission to files in any subdirectory of /var, so I sincerely doubt that they would release a program that requires read/write access to such files, and therefore, I am pretty certain it's a configuration issue, although I'm not experienced enough with the NX server to know where to start looking for the failure. Previous attempts with FreeNX and opensuse 10.3 (I am testing 11.2 for a possible upgrade of all of our linux systems here at my office) yielded totally successful results. the fact that there is no NX server included in the DVD distribution of 11.2 seems a little strange to me, as it was included with 10.3, but this is of little significance compared to my real issues.

Ubuntu :: Unable To Use The FreeNX

Sep 23, 2010

I have Ubuntu 10.04 and I've set up FreeNX server on it. I use the Nomachine client for Windows to log into my home computer while I'm at work.The other day I tried opening Chrome browser and nothing happened. So I clicked it a few more times and nothing. So I went ahead and just used Firefox.When I got home that day I physically went to the computer and woke it up and about 20 Chrome windows were open. So it looks like Chrome is launching in the wrong session. I'm logged in locally and through NX with the same user. Should I create a different user to log into the machine locally? Is there some way to bring these open windows over to my remote session? A couple more things... the first time this happened I had opened Chrome locally and left it open. Also Dropbox does this as well. And locally there is an icon in the top notifications for Dropbox but not on my remote session. So I'm thinking if an app is already running locally can I not open a new instance on my remote session?

OpenSUSE :: FreeNX On 11 Versus 11.1 - What's The Difference

Jan 13, 2011

I have a script that basically adds a zypper repo, then proceeds to install and configure FreeNX.To add the repo:


zypper addrepo Index of /repositories/X11:/RemoteDesktop/openSUSE_11.1 RemoteDesktop

To install FreeNX & it's relevant dependencies:


zypper install FreeNX

To setup and configure FreeNX:


nxsetup --install --setup-nomachine-key --clean --purge
sed -i 's/AllowUsers idcuser/AllowUsers idcuser nx/' /etc/ssh/sshd_config
service sshd reload


After completing these steps on version 11, I can immediately open the FreeNX client (windows 7), and connect. On 11.1, at the very end of the FreeNX connect, just after "Dowloading the session information", I get:


NX> 105 startsession --link="lan" --backingstore="1" --encryption="1" --cache="16M" --images="64M" --shmem="1" --shpix="1" --strict="0" --composite="1" --media="0" --session="" --type="unix-gnome" --geometry="1274x956" --client="winnt" --keyboard="pc102/en_US" --screeninfo="1274x956x16+render"

Permission denied (publickey,keyboard-interactive).NX> 280 Exiting on signal: 15 I've googled this to death, and tried a bunch of random changes to both ssh and nxserver, but I can't seem to get rid of it. What might have changed from 11 to 11.1 that could cause this behavior change? The NXserver seems to be configured and running identical on both systems.
