Ubuntu Networking :: Neatx Or FreeNX For Kubuntu 10.04??

Jun 21, 2010

According to Ubuntu documentation, Neatx should be installed on Lucid but there is no support for this on the Neatx homepage. In fact, the Neatx webpage says they are not doing releases because of bugs. With that said will FreeNx work on Lucid?

Ubuntu Networking :: Freenx Update Broke KDE On Kubuntu 10.04?

May 25, 2011

After a recient update to the freenx libraries KDE on Kubuntu 10.04 stopped working but other desktops like gnome kept running. The problem wasn't in the normal log files, but it was found in the .xsession-errors file in the user directory on the server. After the update NX is trying to start kde with the /usr/bin/startkde4 command which doesn't exist. Instead make a link from /usr/bin/startkde to the non existent /usr/bin/startkde4 and it will work again. To do this use the command:


sudo ln -s /usr/bin/startkde /usr/bin/startkde4

Ubuntu Networking :: NeatX And !M NX Client For Windows - Barely Compatible?

Jun 22, 2010

I have installed NeatX on Ubuntu Lucid 10.04.[URL]..And I use the No Machine Windows client to connect.[URL].. On first glance it is superior to FreeNX because it does incorporate theme and style into the remote session. On longer usage it gets more and more trouble connecting. Basic commands like RestoreSession and Terminate do not work, but get the same reply.

NX> 500 Internal error
NX> 999 Bye.
Sessions still open, not unmounting
NX> 280 Exiting on signal: 15


I can create a new session but I cannot ever ever ever terminate it even after a reboot. What's going on? Is Ubuntu relying on Alpha stage software here?

Ubuntu Networking :: Secure Remote Desktop With SSH FreeNX & DD-WRT?

Feb 1, 2010

For a Secure Remote Desktop on Ubuntu 9.10 here is how I did it using OpenSSH, FreeNX and a router with DD-WRT v24. Pic of it in use at bottom of post, transferring a file and remote desktop at the same time.

For the purposes of this guide I will use a Desktop as the Server (Host) which is at home. The Client will be a Laptop that I can use to control the Desktop remotely. First you should already be familiar with the Terminal which is where you enter commands (anything in a "Code:" box).

In Ubuntu it is in Applications > Accessories > Terminal In Kubuntu it is usually on the lower left taskbar and is called Konsole I am using Ubuntu so you may have to make some adjustments to this guide if you are not using Ubuntu. Installing OpenSSH (for the rest of this guide I will refer to it as only SSH)

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?

CentOS 5 Networking :: FreeNX - Cannot Get It To Connect?

Feb 12, 2010

I am usually the last one to post on forums, but I can't for the life of me get FreeNX working on my CentOS box. I have also read many posts, many how-to's, many troubleshooting guides, and absolutely nothing is working for me. It's Crazy. First of all, I've installed FreeNX before, with little to no trouble. I am not completely green at the linux command line, but I am still no expert. I'm hoping one of you guru's out there can lend me a bit of a hand.

Here goes, I've installed FreeNX onto my CentOS 5.4 dedicated box, using the how-to [URL].. I've done everything, letter by letter, on the how-to. (Installed CentOS, configured sshd_config, added users in AllowUsers, created nx user, imported keys.. etc) At this point, I could not connect to my box, with the error message:

NX> 203 NXSSH running with pid: 336
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options

Ubuntu Networking :: FreeNX Default Key Still Works After Generating Custom Key?

Mar 25, 2011

I installed freenx on my desktop and decided to set up a custom key following this tutorial: [URL]

sudo dpkg-reconfigure freenx-server

Here I chose 'Create new custom keys' and SSH. After copying the client.id_dsa.key file to my laptop, I was able to log in no problem. However, I decided to check and used another computer (running qtnx as a client) to attempt a login with the default key.

It still worked.

Have I missed something in the fine print here? If not, is there a way to fix this behavior?

Networking :: Address Of Remote Network In FreeNX Wizard And Bit Type?

May 21, 2010

Some FreeNX start-up troubles here, need a hand. 1) I am trying to establish a connection from my workplace PC on my workplaces's LAN to my home PC on my private LAN (LAN-to-LAN). Just typing in the public IP of the target LAN in the "Host" field gets me nowhere, as it fails to connect due to a denial at port 22 SSH - even though I've done the forwarding in my home router and punched the required hole in the local firewall of the target machine.

This resembles what I'm looking at: [URL]..2) My home PC is 64-bit Mepis and my workmachine is a 32-bit Ubuntu. Is this a problem?

Ubuntu :: Point To Kubuntu CD Instead Of Kubuntu Repository?

Mar 7, 2011

I would like to apply KDE on my Kubuntu because the current one blew up. But each time I to sudo get-apt it seems to be fetching from the cloud. Is there a way I can make it to read from my local Kubuntu CD? I have both Ubuntu 10.04 LTS and Kubuntu Live CDs.

I believe the local disk read should be faster to translate than to bite the bytes across thousands of miles over the wire right?

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?

Ubuntu :: Configure FreeNX To Not Use Encryption

Feb 2, 2010

I like FreeNX, but it makes the system sluggish sometimes. The server is on Ubuntu and the Windows client are both on the same switch on a private network, and won't ever be use over public internet. I see in the client that I can disable encryption, but how do I do it in the FreeNX server end?

Ubuntu :: Install FreeNX In U10.4 Lucid?

May 3, 2010

Anyone know if it's possible to install FreeNX in Lucid.

I've tried but get an error.

These are the steps I followed code...

Is there anyway to get this installed? Do I need to wait for FreeNX to be updated for Lucid or something? Or does anyone have any suggestion for a RDP server and client? I don't want to use VNC it's too laggy.

Ubuntu Networking :: Kubuntu Can't Set Up Any Network Printers

Feb 15, 2010

I've had Kubuntu 9.10 32-bit running on my laptop since it came out, but in the past month all its networked printers have disappeared from the configuration, and I can't set up any more. I've been through the forums again and again and cannot fix it. I've installed and reinstalled lots of packages related to CUPS but it doesn't seem to make a difference.I'm not sure what has happened, but I have lots of clues. Since I'm reaching the limit of my know-how here, I'll just list all the clues.

I'm pretty sure the problem is in my Kubuntu laptop, because in my SOHO setup I also have a Kubuntu 9.10 desktop (this time 64 bit) connected to a printer, and I have successfully printed through that from both a Windows XP laptop and a Xubuntu 9.10 box.On the Xubuntu 9.10 box, I just asked for the GUI print configurator and it automatically detected the network printer. No muss no fuss.But on the Kubuntu laptop, when I go into the print configurator, here's what happens:

- it shows two options, "new printer" and "server settings" (image a.png)
- entering "server settings" everything is greyed out and unchangeable (image b.png)
- entering "new printer" shows only one option for a connection, "other" (image c.png)
- after entering the address of a printer i know works (image d.png) the configurator has detected the printer (image e.png)
- but then attempting to move forward it crashes with no explanation.

Running the non-kubuntu version of the configurator GUI provides a bit more information before it fails. When I try to access the desktop with the printer attached it wants a username and password. (which wasn't necessary for the two client machines who successfully printed.) And at the end of the process there is an error: "there was an error during the CUPS operation: client-error-forbidden".

Two more clues:
- when I try to go with my browser to localhost:631 the browser can't establish a connection
- but I can see the cups page on the printer's host machine at no problem.

Ubuntu Networking :: Getting Wireless Setup In Kubuntu

Nov 23, 2010

I am a new Linux user and Maverick Meerkat happens to be my first Linux system i installed. Setting up wireless was pretty easy in GNOME as it displayed my wireless system and i just entered the WEP key and i was all set.I decided to install KDE. After i installed KDE i wanted to setup internet There. However the KNetwork manager is not as friendly as Network Manager. It does detect my wireless router, but after i enter the WEP key it does not get connected.

It was asking me all sorts of question like SSID which i did not use in GNOME at all and neither do i know that information.I tried wcid network manager but removing network-manager and knetwork manager.wcid did get connected to my wireless but it was unable to acquire my IP address. (please do note that both k-network manager and wcid network manager work well with wired internet connection). Could you please help me setup internet in KDE? the truth is internet responds better in KDE than GNOME for my computer somehow.

Ubuntu Networking :: Finding The Drivers For Using Kubuntu?

Feb 3, 2011

I have ubuntu installed on my laptop which works fine. It has a pcmcia wifi card. When I tried to run the kubuntu live cd it couldn't find the card. As the drivers will be the same how do I find the drivers to allow me to use kubuntu? I plan to make a live usb which I'll add the drivers to so that it'll work each time I plug in. Alternatively if I can find the drivers then I'll just enable them each time via the cd.

Ubuntu Networking :: KUbuntu 10.10 Does Not Recognize Wireless

Feb 8, 2011

I have recently bought a Toshiba Portege R700-15Q and installed kubuntu 10.04. A similar problem happens with kubuntu 10.10 booted from USB stick. I am a long-time linux user but not experienced with fixing problems. The wireless network is not enabled and it appears that linux does not know that there is a wireless capibility. This is both with and without an ethernet connection at boot. The wireless light on the computer is lit up, but when I go to Manage Connections the wireless and mobile broadband tabs are greyed out so can't be accessed.

iwconfig gives "no wireless extensions" for lo, eth0 and pan0.
lspci returns "Network controller: Broadcom Cooperation BCM4313 802.11b/g LP-PHY (rev 01)"
lshw -C network returns "*-network UNCLAIMED", along with a block of other information which does not indicate a problem to me.

Ubuntu Networking :: Establishing A VPN Connection - Kubuntu 10.10 - 64 Bit

Apr 15, 2011

I have a problem with establishing a VPN connection, it's driving me nuts already. No matter what I try, which packages I (re)install, or how many configuration settings i change.. the result is always the same (see syslog at the end of this post). On the same machine, but on a different harddrive, I have installed Windows 7. The VPN connection works without any problems on this system.

I played already with KNetworkManager, NetworkManagerm, KVpn and so on. Further I re-installed each VPN- and network packages multiple times (eg KNetworkManager, NetworkManager, network-manager-pptp, pptp-linux). Further I tested almost every possible VPN configuration (PAP,CHAP,MSCHAP(v2),EAP,MPPE, stateful encryption, no password, BSD compression)... My syslog is as follow:

Apr 13 18:15:02 defcon-inc pppd[3721]: LCP: timeout sending Config-Requests
Apr 13 18:15:02 defcon-inc pppd[3721]: Connection terminated.

Ubuntu Networking :: 802.1x Dynamic WEP Not Working In Kubuntu

Apr 25, 2011

My university uses 802.1x Dynamic WEP, with PEAP, MSCHAPv2, and no CA certificate. Our IT department actually provides instructions for Ubuntu, and they work, but I can't get it to work in Kubuntu. Here's the instructions using the Gnome Network Manager applet:

- Change the LEAP setting to Dynamic WEP (802.1x).
- Change the Authentication setting from TLS to Protected EAP (PEAP).
- Leave the Anonymous Identity option blank.
- Leave the CA certificate setting to None.
- Change the PEAP version to version 0 if running 8.10, or Automatic if running 9.04+.
- Leave the inner authentication setting to MSCHAPv2.
- Enter your username.
- Enter your password.
- Select OK. A warning message will appear about having no certificate; click Ignore.
- Click Connect.

I'm using Kubuntu 10.10. All the same settings are there for the KDE plasma network manager applet, but the connection always fails immediately. How do I go about debugging this? Is there a way to test this out from the command line? (WiFi in general works fine, on regular WEP and WPA secured networks; just having trouble with this one).

Ubuntu :: FreeNX Authentication Failed For User?

Sep 24, 2010

I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work

Ubuntu Servers :: Get Sound To Work In FreeNX?

Mar 7, 2011

how to get sound to work in FreeNX. After a couple of google searches I'm still stumped to as how I'm supposed to get it to work. The first thing that I'm wondering is: is it possible for a server system without a sound card to actually stream audio towards a client with the NoMachine NX Client (multimedia enabled)? If so then the problem gets a bit more complex. I've installed the ESD Sound Server and PulseAudio. But how am I supposed to do this configuration ? Whenever I go to gstreamer-properties I get the choice for ESD which I choose for my output and ALSA for my input. Still no sound. The configurationfile has been changed so that the libraries for ESD get loaded in /etc/nxserver/node.conf but also still nothing.

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.

Ubuntu Networking :: How To Share Printer Between Kubuntu And Vista

Feb 2, 2010

Is there someone out there that makes something simple that you can network and share a printer between Kubuntu and Vista? I have my office computer running Kubuntu, which also has the printer attached to it. My media machine downstairs is running Vista, which I'd like to be able to print and share files from. I've been doing some reading that you need to use Samba. So, I installed Samba through Synaptic, and it appears that nothing happened. So, I did some more googling, and found I had to install something about system-config-samba, so I did.

I now have a Samba icon under k-menu > System > Samba. However, when I click on this icon, nothing happens. It does nothing (just like clicking on the Network Manager icon, which does nothing as well). So, I am now utterly confused. Is there a way to change samba settings via gui? I'm not comfortable with typing unknown commands into the terminal, as usually there is no explanation as to what's going on. If there was a step by step explanation, that would be ok, but as of now, there is nothing. Is there a simple setup tool out there?

Ubuntu Networking :: Connecting To Wireless In Kubuntu Lucid?

May 14, 2010

I'm having trouble connecting to our home wireless network in Kubuntu Lucid. I was hoping someone here might be able to help. I can connect with no problem in Ubuntu and Xubuntu; I'm having difficulty in Kubuntu only. It might just be me being unfamiliar with the KDE network management app, I don't know.

1. I click on the network icon in the system tray, and choose "manage connections". I click on the "wireless" tab, and click "add".

2. I enter the name of our network in the SSID field (our router doesn't broadcast its SSID; however, if I click "scan" the neighbors' wireless networks do appear in the list) under the "wireless" tab, then I go the "wireless security" tab, and choose "WPA/WPA2 - personal" and enter the password. I click OK.

3. Now when I right-click on the network icon and choose "create network connection", the new connection for our network that I just made shows up in the list, but it has an icon showing a pen on paper instead of the broadcasting signal icon that appears next to the neighboring networks. It also says my connection is "insecure", even though I chose WPA and put in the password. (Neighbors' networks do say WPA, WEP,etc.)

4. I select my network connection that I created above, and click connect, and nothing happens. No connection is created. how the KDE network app works; I've used mostly XFCE and GNOME in the past, but I've heard good things about Kubuntu Lucid and really would like to take it for a spin. However, this computer has only a wireless connection, so I really need to get it working.
