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:

Code:

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

Code:

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:

Code:

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.

General :: Session Timeout - What Is Considered A Idle "session" ?

May 11, 2010

Info about session timeout.

I use tmout = 15 min in my /etc/profile (along with readonly tmout). i have some issues i need to address, looking for ideas.

1. what is considered a idle "session" ?

2. if i & a process to the background and do nothing is this a idle session?

3. if user uses su to a higher level, are there now two sessions? is the tmout for user suspended until su user time outs or leaves su session?

4. i have some users who will run long sql queries. is there a workaround to have the session remain active until process has finished?

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.

OpenSUSE :: NX Nomachine Typing On Its Own?

Dec 8, 2010

I have nx nomachine installed on 64bit opensuse 11.2. All was fine until I ran updates this week and now it seems that it has a mind of its own. (dont remember which packages were updates)Every time I open the cli it just starts typing the equal symbol on its own. In fact every time I open anything that can accept text input it just starts adding equal symbols. It enters them about 2 every second.Code:jason@FileServer:~> =========================I uninstalled all the NX packages, killed the .nx folder in my user folder and then reinstalled the packages and still the same thing.

Ubuntu :: NX (nomachine) From Mac - Capture Alt-tab?

Jun 11, 2010

I'm logging into a remote Ubuntu box from my Mac via NX, and almost everything works great. However, I can't find any way to capture the alt-tab keyboard combination (or, command-tab) for app switching. All the individual keys register with ubuntu, but when pressed together, Mac OS captures it first. Is there any way to fix this?

Software :: Alternative To Nomachine NX?

Feb 3, 2011

Over the past few months Nomachine's NX Server has deteriorated to the point where it's unusable, as detailed in this thread for one machine. On my other machine it works, but I cannot do apt-get dist-upgrades as it spews forth messages like, "insserv: Starting nxsensor depends on stop-bootlogd and therefore on system facility `$all' which can not be true!". So I give up on them.

Ubuntu :: FreeNX No Password Login - NoMachine?

Apr 25, 2011

So I don't know exactly if this is where to put this. Because I think this might be NoMachine's problem, but I'm not sure. I am trying to set up FreeNX, and I got it working to connect from my work laptop (windows 7) to my home computer (ubuntu 10.04).

I have it going on a different SSH port, and it claims I'm using custom Keys. But, NoMachine still requires me to put in a password to connect. But I can't do that because I have my ssh setup to key-authentication ONLY.So I can't connect to my home machine UNLESS I turn on password-authentication also. But I don't want password authentication on. So, how can I connect without using passwords? Do I need to use a different client other than NoMachine NX-client? Or is this a setup I have wrong in my ubuntu stuff.

I figure it must be NoMachine, because I can't even attempt to login if I don't first put in a password.

Programming :: Hashing The Components Of An Tcp Session To Assign/locate The Session In A Hash Table Bucket?

Nov 10, 2010

I have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.

All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

Ubuntu :: Accessing External USB Drives Using NoMachine Client?

Jan 21, 2010

I have an Ubuntu jaunty fileserver. I connect to the machine from time to time using the Nomachine client on windows.Everything is setup and working perfectly, except for one thing. When I acces the server remotely, I cannot access any external USB drives connected to it. The drive mounts fine, and is available when logged on locally to the machine, just not when logged in via Nomachine.

Ubuntu Servers :: Connect Using The NoMachine Nxclient Under Windows?

Jun 8, 2010

I have a remote Lucid machine running Neatx to which I can successfully connect using the NoMachine nxclient under Windows. Using the same connection credentials under Karmic and nxclient doesn't work.

I attach screen shots of the session logs under both Windows and Karmic. They appear identical except for the 'Using shared memory parameters' field. Is this important? No authentication errors appear, so I don't think that's the problem. The Karmic session displays 'Established the display connection' and then fails after exactly one minute.

Ubuntu :: NoMachine NxClient Installed, But Disappears After Restart?

Jan 20, 2011

I have installed NoMachine NxClient deb, on Ubuntu 11.04, Nx installed and I connected to my uni server fine. The Nx program was originally in the applications drop down menu in "others". After a restart Nx was no longer in the menu, I dl'd again and found in Ubuntu software center that there was an option to reinstall NXClient, so I reinstalled and the icons appeared in applications/internet. After a restart they(the NX icons) disappeared again.No other programs have disappeared from the app menu like that.edit: after finding edit menu, I noticed nx client (show) was not "ticked" in internet selection. after a reboot the icon is now available in the app/internet menu.Previous to this I found what I thought was the application in shell $/usr/NX/bin/nxclientbut it would not run from shell command.I added to the panel, created an application launcher for /usr/NX/bin/nxclient and it works there, too.

Ubuntu Networking :: Can't Connect To FreeNX Server From NoMachine

Feb 18, 2011

I have installed nomachine on my windows 7 laptop and when I connect to the server I receive the error message:

"Authentication failed for user [username]"

Which user am I supposed to log in with? Is it the same user as I use on the server or is this a separate nx user? When I receive this message is it because of the user or the ssh key I use?
