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
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?
I am not exactly newbie with GNU/Linux, but definitely new to SSH/NX stuffs. I followed the below tutorials for installing FreeNX so that I can access my desktop like TeamViewer in windows.
https:[url].... https:[url].....
But I don't see the folder NX like the one mentioned here.Then edit the file /usr/NX/etc/server.cfg
I don't see a folder called NX to proceed. Also when I use nomachine client to connect from Windows, it couldn't connect and I get the below errors.
nxssh: <host-name>: no address associated with name.
how to make connect to freenx server from windows using nomachine client?
We have a lab at our school that has DevonIT thin clients. We want to connect to Ubuntu via xdmcp or freenx from these clients, and we want users to be able to connect to our Novell file server from these clients. I can't find instructions on how to install the client, which I found at KDE-Apps.org. It is a tar.gz file. I'm not new to Linux, but rarely install apps from source. Could someone walk me through it, keeping in mind I do not use the command line much? [URL]..
I am trying (desperately) to setup freeNX so that I can access my Mandriva box from my Macbook over my network. I have great need to be able to do this. Here's the necessary info for you: Mandriva PC: running Mandriva 2010.0 with freeNX installed from the Mandriva repos Macbook: running OS 10.4 with the Nomachine NX Client installed Now, I have followed the setup from the Mandriva wiki as well as the freenx wiki to no avail. I simply cannot connect the Macbook's NX client to the server. I get an authentication failed message. However, I can ssh from the Macbook to the server just fine (that's how I'm getting most of this work done).
After making many updates via pup, including FreeNX, my FreeNX installation has broken. It worked flawlessly before the update. Now when I try to connect my client connects, I see the NoMachine splash screen and then I lose the connection with the following details:
Info: Display running with pid '3404' and handler '0x1a037e'.
NXPROXY - Version 3.1.0 Copyright (C) 2001, 2007 NoMachine.[code]......
Also, I would like users to authenticate against using LDAP rather having created manually in the NX server. I installed using yum install freenx nx and rename the node.conf.sample to node.conf and installed the windows client. but when I am trying to conenct the nx server it says it is connected but it gives me NX> 202 Authenticating user: nxNX> 208 Using auth method: publickeyNX> 204 Authentication failed.I have change this nx user in sshd_config file to user that i created using nx server command which exists in local machine.
Sorry if this is in the wrong group but its a bit of an odd one but I think comes under Server Support.. I've set up both x11vnc and freenx in an attempt to eliminate either as a cause for this issue. The problem is that when I log in with either, I can get into the desktop and run things from the menus but when I make the System menu active - the session hangs and you have to killall for the freenx or vnc processes.
I was wondering if anyone might be able to help me investigate this and hopefully fix it as I'm not sure where to look given that both types of remote connection seem to have the same issue.
I've created a brand new CentOS 5.4 (Final) 64bit machine AMI on Amazon EC2. This was based off an existing image. I was able to follow the wiki to add NX server. I am using WIN XP desktop for NX client.
I can connect to the EC2 machine and get the GNOME desktop fine. I see the usual CentOS desktop and poke around.
Q/Problem:
I expected to open the Terminal window and get a shell prompt to su into root user (I need to be root to install some software that needs GUI). I do not want to install this from my plain SSH connection to EC2 (hence the NX server etc.).
When I open the Terminal window, all I get is the NX>105 prompt. I need to get to a shell prompt so I can su into root. For life of me, I cannot get around this prompt (I looked at NX documentation too). Note that this is a prompt NOT on client but on the remote machine. I do not need this as I'm already authenticated and logged in to remote GNOME desktop.
Obviously the TERMINAL is running some NX start up script (I've no idea which one). If there is some other way to sudo into root?
I've installed from the CD the Centos version 5.5. When I try to connect to Internet I can't because I received some errors. I've the Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) Ethernet Controller also a wireless slot (I've the wireless card DWL-G650+) When I turn on the pc and I go to "Ethernet Device", I see set: peth0 (Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) ETHERNET CONTROLLER) and also set "Bind to MAC address": fe:ff:ff:ff:ff:ff I've set manually the IP address (I'm under router). Status is "Active" but can't go on the Net. When I change to "eth0 (Intel EtherExpress/100 driver)...sometimes become "Active" an other times said that the MAC address is different or to check the cable because can't find the IP. What can I do?
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?
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)
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:
I installed freenx on my desktop and decided to set up a custom key following this tutorial: [URL]
Code: 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?
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?
i bought a vps last week. I wanna if it is possible that the only connection on my computer will be to the vps(i wont be able to connect directly to the internet for example) and if i want to connect to the internet it will be through the vps . i wanna use ssh and especially iptables(and not the proxy of the browser)
I'm using CentOS 5.4. I want to set-up a PPTP connection (I'm the client). I installed the NM pptp plugin from EPEL's repository. I have configured my PPTP connection in the NetworkManager applet but now I don't know how to connect to the server, I mean, there's nothing like 'Connect now'.
I have recently installed CentOS 5.3 in my system. I needed some help with the wireless configuration. Actually i have configured it and it shows the wireless name but it doesnt connect to it. in solving the issue.In the /var/log/messages , the following error appears :
I have a server in my house with webmin and virtualmin installed et i made a mistake.Ive created a virual server and ive change the lan ip adresse. 192.168.2.30 ive change it for 192.168.2.31.Now of course nothing work. Im not able to connect via ssh via another computer.So, on the server i write ifconfig and it tell me the adresse is 127.0.0.1 and no more adresse like 192.168.x.x.
I just moved into a new apartment and now connect via DHCP. Everything seems fine network-wise, except that when I'm at work I can't connect to the home box. (CentOS 5.3 x86_64) One thing I noticed is that I can't really determine my "true" IP address. What I mean is that it looks like my IP is 192.168.0.190, but when I use linuxdcpp, and enter a hub, I'm told my IP addr is actually something like 71.192.163.206. Here's some info:
I have a box that I installed Elastix on as I'm trying my hand at Voip and Linux. I'm basically very green when it comes to Linux and the console. As I was following a guide @ engineertim.com to securing the box, it asked me to: wget [URL], But I get: Resolving engineertim.com... failed: Temporary failure in name resolution. I searched around and tried configuring resolv.conf to no resolve - :) unintended pun
I changed /etc/sysconfig/network to include GATEWAY=192.168.1.1 From the internet I have a modem-192.168.2.1, a telecom voip box-192.168.15.1, and then my router 192.168.1.1 I'm able to ping machines attached to the router but nothing beyond that. I tried to get the results for ifconfig via putty on this machine but it says command not found. I can get it when I log in at the box in question though.
I'm trying to set up a server for an NPO who connects to the Internet through an internal proxy (Websense). I can't access the Internet unless through the proxy.
Since it's a server I did not install a GUI so I'm wondering how to connect the new server to said proxy server. I have the IP address, port number and username-password for the proxy server. The new server has a static IP address and is ready too go!
I am trying to connect my Asus EEEPC to an option icon 431 usb modem.
I have successfully installed the HSO driver however am unable to connect through network manager. I have successfully connected through Rhel Beta 2, Fedora 13 and Ubuntu 9+, however, desperrately want to be able to use centos 5..5
working to sort out the damn wireless for too long. Mine in cent05 5.2 . network manager is on and I can see the icon on tray. It list all the wireless connections too, but just won't connect. WPA encry is disabled. further details below:
