Hi everyone,
When I opened FoamX window by typing "FoamX", the FoamX window appered, but told that "Default name service could not contacted" I am using 64bit Fedora core 4. I installed all 5 files of AMD Linux 64bit version. Also I found one of the OpenFOAM discussion saying that "for fedora core 4 users you need to install xorg-deprecated-libs, just do yum install libXp.so.6" So I did this. When I opened FoamX, I first typed export WM_64="on" and type . .bashrc and type FoamX Then it tells "Defult name service could not contacted" and also shows the following messages Starting NameServer with inet:localhost.localdomain:1234 ... Starting FoamX Host Browser with inet:localhost.localdomain:1234 ... /*---------------------------------------------------------------------------*\ | ========= | | | \ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \ / O peration | Version: 1.2 | | \ / A nd | Web: http://www.openfoam.org | | \/ M anipulation | | \*---------------------------------------------------------------------------*/ Exec : FoamXHostBrowser Date : Feb 06 2006 Time : 15:00:59 Host : localhost.localdomain PID : 24614 Root : Case : Nprocs : 1 HostBrowser running.....

Hi Yoshiki,
Did you install j2sdk1.4.2_05.linux.tgz for java? FoamX needs java tor run. Maybe this is the problem? Regards Jens |

Yes, I installed j2sdk1.4.2=05.linuxAMD64.tgz in $HOME/OpenFOAM/linuxAMD64.
And when I executed the 'foamInstallationTest', there was no error. |

Probably your nsd isn't running. This is the Mico name server that gets started by the runFoamX script. Put some print statements around the invocation and see with what arguments it gets called and if it runs after that.
I don't tend to run FoamX in 64 bit mode so cannot comment any more specific. |

I had the same message on a 32bit machine with Fedora 4. If you turn off the SELinux security (and reboot), FoamX will work. Desktop->System settings->Security Level. No doubt it is possible to more selectively open up whatever FoamX needs...

Hello,
Yoshiki, FoamX and the Foam Host Browser (runFoamXHSB) does not run with the computer name set to "localhost". You need to provide your computer with a name other than "localhost". Rita... You need to have something like this in your /etc/hosts file: 127.0.0.1 localhost.localdomain localhost <name_you_choose> And you dont need any reference to your local computer IP address in /etc/resolv.conf Now... if you make this change to only your /etc/hosts file, I think it will be overwritten at the next reboot... to prevent this, make the same change also to the file: /etc/sysconfig/networking/profile/default/hosts And again, you dont need any reference to your local IP address in the copy of the resolv.conf file which also exists in /etc/sysconfig/networking/profile/default Also, you need to remove the symbolic link you made for the hosts file.... Try this out, it should work. As for those who run Fedora linux systems with SELinux enabled.... there is no need to disable SELinux, all you need to do is, to go to: Administration-> Security Level and Firewall-> the SELinux tab-> Modify SELinux Policy And under that... in the list.. go to: Memory Protection, and put a tick next to the option: "Allow all unconfined executables to use libraries requiring text relocation that are not labeled textrel_shlib_t" Close and restart your computer, and that should solve the remaining problems (provided your hostname is not set to "localhost" or "localhost.localdomain" :-)!!)

Hello Pietro,
Sorry for the delay.... wasnt at home! So... You are using a Fedora Core 4 installation. In this case, you need to go to SELinux->Modify SELinux Policy -> "Compatibility" , and put a tick next to the option...: "Allow the use of Shared Libraries with Text Relocation" But, just to be sure, can you probably give me more information regarding the error message which FoamX puts out before it quits? Have a nice weekend! Philippose |

Hi Pietro,
Looks like your default SELinux settings are not allowing the FoamX system to start up as it should.. One thing you can try is.... enable SELinux again, and reboot your system (to re-enable all the SELinux policies). Then... run FoamX. After FoamX quits with the "Unable to contact Name Server" error, login as root in a console. And then, at the prompt... try: audit2allow -M local < /var/log/messages This command looks into your log file, and tries find the different requests which were blocked by SELinux, and creates a set of policies to allow thse requests in the future. Once the command is run, you need to run the following command: /usr/sbin/semodule -i local.pp And then... reboot the computer. When you run "audit2allow" if it comes up with an error asking you to install the checkpolicy rpm package... use yum to install it using: yum install checkpolicy Hope this helps.... I havent tried it myself, but theoretically this should work :-)! Philippose |

Do your Linux distribution use nscd (the name service cache daemon) by default? If so make sure nscd is up and running. I got the same 'Default name service could not be contacted' GUI message box when I turned off nscd on SUSE 10.1.

I have the same problem.
When starting FoamX there is this message: A server already seems to be running. (Detected server reference /home/sega/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/apps/FoamX/ns.ref) Do you want to kill this server? (n) I cant do anything except typing "n". Then the message "Default name service could not contacted" is displayed in the FoamX-GUI. What is the problem? FoamX was working well until today ...

It sounds like the name server isn't responding to requests. Try killall -w -9 nsd in a shell session, then try to run FoamX again. Regards, Graeme. |

Sebastian,
on a closer reading of the man pages, I was right the first time, and the first option in my second message here was okay too. The second option in my second email might not work. You might ask why you are getting this error in the first place, and why FoamX won't kill nsd for you. The answer is that a normal kill uses the SIGTERM signal (15), which can be blocked. There are a couple of signals which cannot be blocked, and this SIGKILL, number 9, is one of them. Which makes me think that perhaps this isn't your problem. When you say "I cant do anything except typing "n"." do you mean that you don't get any further if you type 'y'? What happens, exactly? Regards, Graeme. |

Well, I could solve this problem by deleting (renaming) the /home/sega/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/apps/FoamX/ns.ref file.
Now everything is running as usual. When I was typing "y" the program was simply quitting.
