Fedora :: NoMachine NX Error 112 'Address Already In Use'?
May 15, 2011
NX works great when only one connection is attempted at a time. Each server responds appropriately. However when attempting to use NoMachine from an XP client for multiple nx remote connections all subsequent connections receive the following error:Session failed - NX Server Error is 112 'Address already in use'.Research indicates numerous discussions (see below) with no solution for the current freenx versionEnvironment:VM Platform default Fedora 13 with KVMVM machines all default Fedora 14 with "yum install freenx"Full Text of Error Message:
Info: Display running with pid '2336' and handler '0x17040e'.

This morning it would not boot; when I tried to wake up the system, it gave me a bunch of errors, the last ones being as follows: "mount error: could not resolve address for servername: No address associated with hostname mountall: mount /media/shares [1402] terminated with status 1" I am writing this in Win 7 since I lost ubuntu. I am using ubuntu 11.04.
I use Fedora 12 and newest free NoMachine NXServer. I have installed all three packages (nxclient, nxnode and nxserver). I'm running sshd on port 22. When I try to connect to my machine, everything works fine, then I see big red M and then is all black.
I am working on implementing a protocol on NS2.34 .I really need help to solve this problem . Actually , I don't now whether the problem is generated by the tcl code or the c++ code when I run the simulation, I get this result :
Code: num_nodes is set 64 INITIALIZE THE LIST xListHead 34 45 channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 SORTING LISTS ...DONE! code....
Every time I upgrade my system I run a post install script. This script made some harm to the network start that prevents sshd from starting, but I was unable to detect the problem. In my boot.log I found this:
[...] Starting NetworkManager daemon: [ OK ] Starting Avahi daemon... Jun 2 14:58:48 Antares kernel: ADDRCONF(NETDEV_UP): eth0: link is not ready
[code]...
So there is a "bind to port 22 failed" probably caused by "eth0: link is not ready", but after the sshd init script fails the eth0 is ready...
I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use [user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails. Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?
I installed the Centos 5.5 and after the Xen. After I put a virtual machine named VM01.Initially it worked properly, I tried everything and it worked.When rebooted, I had problems with the network.I have two network cards eth0 and eth1, but eth1 does not have any ip and I use only eth0.The error that appears is:
vif0.0: received packet with own address the source address
Fedora 11, new install from live cd newest nomachine free server and client for linux fedora server to fedora/windows clients connection. I cant use most superuser programs in gnome, when logging in with nomachine. I can start a program like "add/remove software" and search for the software and get results. It can search for dependencies, but when i push "install", the "files that will be installed" window just closes, and I get back to the main window. Nothing gets installed.
This is the behavior in most such programs. I kind of get the feeling that these programs are either ignoring su actions, or trying to display the "autorization request" or password window locally. Also, when selinux stops something, and i get a star up in the right corner, I can't "show" the message. It just closes the bubble and goes on with its business. I just installed fedora over ubuntu. Ubuntu behaved like i wanted it to in this regard, giving me the power to install and change stuff, and displaying the password request every time it felt the need to. I don't want to go back to ubuntu.
I can ofc ssh into the server, and use yum and such. But i don't want to if i can get away with it. I don't care about the security issue. I have a fairly good fw/router and only one idiot user (me), and he can blame himself when his surfing lets the bad guys inside. So, what i want is to do administrative tasks via nomachine.
I'm only partially new to Linux. I'm running Fedora 11. I've just set up two machines, I thought to be identical. Evidently I missed something. I had some problems getting the network started on the second machine, and I must have forgotten a name change somewhere. Anyway, after doing lot's of comparisons between the boxes, editing and renaming and re-linking the ifcfg-GigaStorey file, they are both functioning. The problem is that whenever I start or restart the network on box 2, it reports the following error:
Bringing up interface GigaStorey: RTNETLINK answers: File exists Error adding address 192.168.1.6 for eth0. [ OK ] The file ifcfg-GigaStorey is linked in the following directories /etc/sysconfig/network-scripts /etc/sysconfig/networking/devices code....
Like I said, it's not super critical, just annoying. The networking comes up ok, but the error is puzzling. I figure if I learn what this problem is I'll be one step closer to my Linux beanee.
I have installed fedora 13 in my system. httpd server is also installed. when I tried to start the service of httpd, following error message displayed: Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
I have installed XAMPP on my system and started it just fine, but for some reason when I type "http://localhost/myDirectory/index.php" into the address bar of a browser, I get a 404 error. I followed the instructions hereand after creating test.php, I was still not able to view it. Can someone please tell me what I am doing wrong?
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.
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?
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.

Note : Doing this way ( recommanded by apache documentation ) I don't know if it is the good way as recommended by NOMACHINE documentation : <<It can be updated by adding the following directive before the "Global Environment" section >>
The problem is that I have three PCs two with opensuse 11.4 and one with windows xp both linux machines have installed nxserver for remote control and the xp machine has nxclient, I can connect to both linux machines with the windows client, but when I try with the linux client to the other it outputs the following error:
[code]...I changed the ssh port to 2222. this is the nx software from nomachine the client version is 3.5.0-6
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.
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.
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.
I'm trying to restrict command line ssh and yet keep NoMachine working, so I followed this post [URL]... and tried adding this to /etc/ssh/sshd_config:
On restarting the ssh daemon other users can't login by the terminal, but I can. However, NoMachine won't log me in. I get: NX> 502 ERROR: Public key authentication failed. As a server side check:
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.
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 want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.
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.
I have done a basic installation for a server.And then I have removed the screen and the keyboard because I have no place for them.I manage the server from my laptop using NX.I am using the root user account as nx user because I can't stop the server with a normal user.
When I connect to my Ubuntu box from any Mac OSX 10.6 client (Snow Leopard) using Nomachine, the 'd' key minimizes all windows on my Ubuntu box. I found another post here that says the issue can be fixed by changing some settings on the Ubuntu box when connected. However, I cannot find the location of the settings indicated in that post [URL].
Does anyone know how to resolve this 'd' key problem?
This thread (nxserver now broken?) has inspired me to install FreeNX and the client from nomachine on openSUSE-11.2 (this is the version used on both, server and client machine). The good news is: basically it works. I can connect and get the desktop. However, I have some trouble with the keyboard. Up and Down arrow keys do not work. The up arrow triggers a screen snapshot. The down arrow key does nothing. I tried to connect using qtnx as well. This does not work. Result is:
When I install the FC11 by using"Install or upgrade an existing system"or"Install system with basic video driver"mode...Point 1, I can't config the network config ( IP Address ), due to theerror of network manager...Point 2, I can't enter into the text mode to do the installation steps.Remark:The machine is provide Web,DNS, and Mail Server on the NET ( Internet )
