I always notice that xdmcp always runs on my system. I don't want it to. These are my settings and I tried to reboot. xdmcp still runs. How do I stop it once for all.

I heard that window managers like xdm, kdm and gdm etc use xdmcp protocol which is inherently unsafe. Now I have an Xclient that has to be displayed on multiple Xterminals. Can I do this without gdm/xdmcp. Shouldn't the regular X work in this case. What exaclty is the purpose of gdm/xdmcp on top of X. So if gdm provides the complete desktop manager, does this mean it is unsecure since it uses xdmcp?
View 3 Replies View RelatedI'm on a private network and would like to have XDMCP turned on so different users can access the system with a greeter and log in to their own desktop.To test if this works, I've tried 'Xnest :1 -query localhost' - which on other _nix systems will bring up the greeter, then I know that all I have to do is deal with firewall issues, etc. On Ubuntu 11.04 I just get a blank screen.I've seen others asking for help with XDMCP, and the answers are to use VNC, which from my experience allows you to _share_ the current desktop, not create a new one for a different user to use at the same time. If I am mistaken please let me know.So, any ideas on how to get XDMCP up and running on Ubuntu 11.04?

I have an openSUSE 11.1 and I noticed that after installing a couple of things on it the sshd is not starting anymore on reboot. how can I debug this problem. Is there a log file so that I can see what was the problem? If I want to use ssh I have to start it from yast every time the computer restarts.
View 7 Replies View RelatedI am trying to have accessible computer by its network name (same as hostname) by ping and Samba client from other computers and one directory shared on my laptop. I simple, trivial wish I hope. Nothing extravagant. Something what every Windows user has out-of-the box, just to select a shared directory. However I struggle hard to do the same with linux. Sharing directory with samba is relatively easy, the issues I have is with my laptop network name. It is not recognized/propagated to the local network.
I cannot rely on static data in /etc/hosts. This is a laptop not a server, I move it between different networks. To achieve propagation of my network name (hostname) dynamically, so everyone in the local network can at least ping me, I was advised to use winbind (winbindd), that is to rely on MS NetBios technology There is no native linux technology to achieve this? shame! what about plain/dynamic DNS? why it is not my network name not propagated to my local DNS server/wifi/rooter?
To do that I was advised to do:
- run winbind service (winbindd daemon)
- run samba service (umm, not sure if this is necessary for network name propagation, but I also want to share data so lets keep it as an essential).
- add "wins" to /etc/nsswitch.conf to "hosts" section
Well, it seems to work on my other two computers with Ubuntu and Mandriva well. But not on Suse. Well, not completely, not permanently. It magically start working when I call "Yast -> Samba Configuration". No change here (everything is already set: Domain Name, Not a DC, Netbios Hostname, Wins server support=yes, use Wins for Hostname Resolution) just hit OK. It runs SOMETHING in the background (some scripts) for a few seconds. And then abrakadabra, everything is fine, my network name is recognized, everyone can use my samba exposed directory, smb4k sees me in the Network Neighborhood.
BUT when I restart, I am "back in square one". Pinging my name does not work, smb4k does not see me, or cannot find me even by IP! Samba sharing works by using direct IP. Not all clients support connecting by IP notably not smb4k. To use Samba properly you have to sort out network name visibility fist. I would like to make "Yast -> Samba Configuration" achievements somewhat more PERMANENT.
What exactly runs when I hit OK? No new server/daemon was started. I checked PS, nothing with newer PID appeared. And samba and winbind are started on boot, they were running indeed. No change in configuration was made. I checked all changes made in /etc - but none found! Where is winbind configuration? smb.conf? Do I need to run wins server/client, another daemon?
my problem is that i am only connect mi laptop dell inspiron n4010 to the internet wired or wireless only if reboot pc, doesn recognize any network if i turn on my pc and then connect wired or wireless..

I updated my NetworkManager from version 0.9svn1128615-2.2 /opensuse/repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.2/i586/) to the newest version 0.9svn1128615-138.2.The result was, the after reboot an error message occured, saying that the KNetworkmanager is not working and it would be not able to start the program !Did anybody else have the problem with this newest version?

I have installed VMWare on my laptop. Host operating system - Opensuse 11
Two virtual machines - Both of them have Opensuse 11 as Guest Operating System.
When I start both virtual machines I get the following message.
"Message from <local host name> : The network bridge on device vmnet0 is not running. The virtual machine will not be able to communicate with the host or with other machines on your network. Virtual device Ethernet0 will start disconnected"
I cannot ping to another Virtual machine from one virtual machine. I get "Host Unreachable" message.
I've been working on getting NoMachine and FreeNX working together ... and they're both working well, listening on different ports (guess I should write a howto). At some point I decided to write an init script to control FreeNX behaviour (start, stop, status, setup), since the Ubuntu version has one (called freenx-server) and openSUSE doesn't, but I noticed that it was not necessary, as FreeNX got started automatically... but how ? I could not find any init.d script or command which would start the FreeNX server. Indeed it wasn't actually running :

Just installed OpenSUSE 11.2 and I have to say it feels great.Only gripe I currently have is the NetworkManager that is starting up very slowly. When I have logged into KDE KNetworkManager applet says that NetworkManager is not running and hence I have no network connection. This is fixed if I start NetworkManager (as root) or just wait a couple of minutes. I have one ethernet interface only, no wireless

So I figured out it should initiate a batch job.However, the HTTP server process cannot initiate a batch job because user wwwrun is denied access to service at. Why is that so, and is it safe to remove this denial?
View 9 Replies View RelatedI have a little bit of a problem, I run openSUSE as a server on a Dell PowerEdge T610. I use it for sharing files in a local network and as a web server accessible through the public IP (configured through router DMZ). Also, I use Teamviewer for remote control in order to avoid some compatibility and network problems. Generally the computer runs flawless but from time to time, as about once in two weeks, all network related services except the Apache server which runs just fine, and is still accesible, crash. The Samba share can't be accessed anymore, the Teamviewer is also dead and the only way to put everything back in order is a restart. The thing is I don't know if an error occurs since the server hasn't got a monitor installed, and more than that I do most of my work remotely (as in miles and miles away from the location) and it takes me quite some time to actually get there and see what's happening.
So, any ideas what might be happening? I belive that there might be some information in some of the logs, but as I am not an expert in Unix like operating systems I don't exactly know where to start from.
Earlier I have no problems when I install opensuse. After installation the network runs and I can run online updating in yast for the system. But since a few version it doesn't work after installation and I don't know why. I think maybe the errors could happen because I have no
internet connection. Today I install 11.4 and get this message when I want to run online updates in yast.
There is an error in the repository initialization

I think this problem stars with 11.1 or 11.2.

Hi. I have Ubuntu 10.04, nm-applet is running in the background, my battery icon and sound icon are showing but my network icon has been missing for the past 2 days. It was working fine before but now it's not. How can I fix this issue if I don't have an ethernet cord? Is there a way to roll back the recent updates or do I need to reinstall my network manager?

running a server semi-headless (desktop installed, but usually I connect via ssh/freenx) on my network.after rebooting the box, the samba service will not respond to clients, until I login over nx, and restart samba with 'sudo service smbd restart'. I have it rigged via startup applications, so the command runs on first login, but I would really prefer it come online on boot even if I'm not there to logon. I wrote a quick script to enumerate the status of the network services. here is the output right after a reboot. I ran the script from ssh, before starting a desktop session with nx.

running Debian Squeeze (standard 32bit squeeze Kernels linux-image-2.6.32-5-486 and linux-image-2.6.32-5-686) happily without trouble on a 64bit capable Samsung laptop featuring an Intel T3200 Dualcore processor. However, when I try to boot using the squeeze 64bit kernel (linux-image-2.6.32-5-amd64) the system proceeds through a few text lines immediately after Grub, and then performs a warm start.
The text output I get immediately after Grub look similar to the ones I get booting the 486 and 686 kernels, without any indication for the reboot behavior. The rebooting also seems to happen before any entry is written into the boot/system log files (logging is enabled). This behavior also occured when I first tried to prime the machine from the Debian squeeze install CD using the amd64 kernel. I'm generally happy with the 32bit kernels, but I'd like to use the amd64 support to do some Java compatibility testing for 64bit architectures.
The Laptop is a Samsung R510-Aura T3200 Delfina with the following Hardware and Setup (using Grub as boot loader):
- Intel Pentium Dual CPU T3200 @ 2.00GHz (see http://ark.intel.com/Product.aspx?id=37160 for details)
- NVIDIA GeForce 9200M GS
- 3GB RAM + 1GB reserved for GeForce
- Konfiguration Details:
-- Phoenix Bios
[Code]....
Maybe a strange BIOS-Setting that works with the 32bit kernels but not with the 64bit kernel? I've seen a post on here that indicates someone is running the amd64 kernel on a T3200 successfully, and the chip is definitely 64bit capable, so the reboot behavior is a complete mystery for me
on Debian/Ubuntu in the login form (i suppose it's "gdm") from the bottom right corner I can pick the option to login to a remote XDMPC desktop (that of course I enabled on the other side..) the network is checked for those open XDMCP service and finally, the login box appears and i can remotely login to a "graphic terminal".
How can I do the same in Fedora? I found some guide about Xnest, Xzephyr, but I was totally unable to find a way for doing this simple task.
I want to run a system that acts as a basic file server, I want to remove the graphics card for the sake of power saving and less heat in the box. My machine can boot without the GPU, and I can ping it and use putty to do things, but I'm still new to Linux and don't really know what I'm doing so GUI is best for me atm.
From somewhere I picked up that this is possible (the XDMCP server machine can have no GPU). This post here [URL].. seems to be what I am looking for, but I don't know how to "convert" these instructions to Ubuntu (the files mentioned do not exist on my install anyway).

This applies to GDM as well, but I'm using KDM right now so:
Linux 2.6.31.12-174.2.19.fc12.x86_64 #1 SMP x86_64
I setup XDMCP:
/etc/kde/kdm/kdmrc
[Xdmcp]
Enable=true
Willing=/etc/X11/xdm/Xwilling
Xaccess=/etc/X11/xdm/Xaccess
[security]
AllowRemoteRoot=true
DisallowTCP=false
/etc/kde/kdm/Xaccess (link to the xdm 'xaccess' file) includes:
* CHOOSER BROADCAST
In KDM settings I set it to 'no theme' and 'no custom background'. IPTables & SELinux are both off. The client & server are both on the same switch. I can connect successfully. But all I get is a black screen & an X cursor, never get to see the login prompt. Most things I find have to do with the inability to connect at all, but this connects. I'm having this problem on RHEL5.4, CentOS5.4, & Fedora 12. I'm troubleshooting it on Fedora though. I'm not able to even log in.
I must point out that for CentOS5/RHEL5 I got this working, but I didn't do anything differently that I know of. I just repeated the same process over again....but I'm using GDM on those. Is it possible that I may have to use GDM for KDE because it works with GDM? I'd like to get KDM working because that's what it's designed to do right? work the way it's configured. I've not had a chance to look into it with KDM since the time that I posted this thread.
I had Xming working great with XDMCP on my Debian 6 server at work. I had to replace the UPS and when I brought the machine back up xming/XDMCP no longer worked correctly. When I launch Xming and connect to XDMCP session I get the Xming window, the X Cursor but the GDM login window never appears. So I am getting some level of connectivity.
