Having trouble with FreeNX, Need help to make it work perfectly
by Kai Yang Tay 26 Apr '07

26 Apr '07

Hi thanks for the reply i am really grateful if you can tell me how to make FreeNX work like charm. I am really stuck with it, and after reinstalling the server is definitely pissing off my boss. Please help me thanks. =========================== Please let me review how my FreeNX was screwed up. After i fresh install my CentOS 5, I 'yum install freenx' and so if i am not wrong I actually install freenx 0.5.0-12 or something.... but i think ya shd be -12. Ok... so after i install freenx through yum. I follow what's on http://wiki.centos.org/FreeNX I --adduser and --passwd etc. Then copy the /etc/nxserver/client_id*.key over to my NX Client on Windows. Initially all works out. The NX session starts and i can do what i want over this remote session, and i proceed with updating of the critical updates for other apps from yum. The problem comes after i do this, right after the yum update. I choose to reboot my server. I reboot the server over the NX remote session. By going System -> Log Off -> Reboot. The NX Client's Window automatically closed (in quite a violent way with error msg). Then the server reboot. After the reboot, I try to reconnect to Server again using NX. But this time it fails with the following message. ==================================================================================== NX> 203 NXSSH running with pid: 5940 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options NX> 200 Connected to address: 192.168.1.5 on port: 22 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey HELLO NXSERVER - Version 1.5.0-60-SVN OS (GPL) NX> 105 hello NXCLIENT - Version 1.5.0 NX> 134 Accepted protocol: 1.5.0 NX> 105 SET SHELL_MODE SHELL NX> 105 SET AUTH_MODE PASSWORD NX> 105 login NX> 101 User: root NX> 102 Password: NX> 103 Welcome to: XQSVR200611 user: root NX> 105 listsession --user="root" --status="suspended,running" --geometry="1280x1024x32+render+fullscreen" --type="unix-gnome" NX> 127 Sessions list of user 'root' for reconnect: Display Type Session ID Options Depth Screen Status Session Name ------- ---------------- -------------------------------- -------- ----- -------------- ----------- ------------------------------ NX> 148 Server capacity: not reached for user: root NX> 105 startsession --link="lan" --backingstore="1" --nodelay="1" --encryption="1" --cache="32M" --images="64M" --media="0" --session="XQSVR200611" --type="unix-gnome" --geometry="1280x994" --fullscreen="1" --kbtype="pc102/en_US" --screeninfo="1280x1024x32+render+fullscreen" NX> 1000 NXNODE - Version 1.5.0-60-SVN OS (GPL) NX> 700 Session id: XQSVR200611-1000-1279B1D659A32AEF7AA88D7C50CA5619 NX> 705 Session display: 1000 NX> 703 Session type: unix-gnome NX> 701 Proxy cookie: 64b824b7aa9edb0a55c6e220710fba3c NX> 702 Proxy IP: 127.0.0.1 NX> 706 Agent cookie: 64b824b7aa9edb0a55c6e220710fba3c NX> 704 Session cache: unix-gnome NX> 707 SSL tunneling: 1 NX> 1009 Session status: starting NX> 710 Session status: running NX> 1002 Commit NX> 105 /usr/bin/nxserver: line 1190: 6719 Terminated sleep $AGENT_STARTUP_TIMEOUT NX> 1006 Session status: running NX> 596 Session startup failed.

I really do not know what's wrong. When i try to connect back locally at my server. The GNOME UI is gone! I am now left with only the console logon menu. This same problem happens everytime, even with CentOS 4.4 recently. (In the past, ard DEC 2006, I did the exact same thing on my CentOS 4.4 Server, it works without any problem EVEN with the same violent exiting way, I have never have a problem connecting back to the server. But recently after i failed my installation of CentOS 5 and go back to CentOS 4.4, the problem starts to occur like what i have mentioned. And I really did what was written on the wiki, nothing i have done now is different from what i did in the past.) Please, and sincerely please. Guys, if you all know what's wrong please tell me, how should I solve it? Did I miss out something? like installing of NX Node or NX Client on the server etc? Well explained or guide is really appreciated. Thanks, really Thank You.

Update Centos-4.4 to centos-5 spents a lot of time in "restorecon"
by Joachim Backes 26 Apr '07

26 Apr '07

Hi, having running centOS-4.4 on a really fast machine (16 GB memory, 8 Opteron CPU's, SATA drives). Then making an update by using the Centos-5 CD's. The start was fast, but during update, the installer spents a very, very long wallclock time during selinx updating: for about 1/2 hour the updater runs in a restorecon/find sequence. And at the end, before the MBR is written, it spents again a long time in "install". Can somebody explain this?

Centos 5 -- Bind not
by Robert Moskowitz 26 Apr '07

26 Apr '07

Well, I just did my 2nd install. (Now doing the updates via yumex and stepping into the updates instead of risking doing it all at once.) I selected every bind related package, and then ran the BIND configuration GUI in System>Adminstration>Server Settings. Things seem to work. So I uninstalled and reinstalled on my new DNS server and it looks like I can proceed on the install.

XVideo vs OpenGL
by Ioannis Vranos 26 Apr '07

26 Apr '07

Hi, I have a Pentium III PC with NVIDIA GeForce 7300GT on an AGP 8x and am running NVIDIA driver 9755 on CentOS 5.0 x86. What is the most efficient playback method for the various players, XVideo or OpenGL? RealPlayer has a "Use XVideo" tick box under the "Hardware" tab preselected, while MPlayer uses xv - X11/Xv, gl - X11(OpenGL) and other Video drivers. What is the most efficient between the two, given the configuration?

URGENT: Skip installation ix86 packages from kickstart on 64bit arch?
by Robinson Tiemuqinke 26 Apr '07

26 Apr '07

Hi, Has any one know how to skip ix86 packages from installation in Centos kickstart? Most of our machines have 64bit Intel/AMD CPUs, and it make non-sense to still keep 32bit compatibility. Even worse of i*86 packages is, when upgrade we have to recompile both ix86 version and x86_64 version to get an automatic yum upgrade. I know we could use 'exclude' option to exclude i*86 packages from yum calculation/upgrade; But, if this can be extended to kickstart? Thanks a lot. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Hi, curently running centos4.4 with a board having promise sata controller. If I try to update to centos-5, the installer hangs up. No problems under centos-4.4. Does somebody know a workaround for this problem? In the mailing list archives I found a similar report, but no solution.

Re: [CentOS] Strange content in the kernel dmesg traces [SOLVED]

CentOS 5 x86: Hibernate
by Ioannis Vranos 25 Apr '07

25 Apr '07

OS: CentOS 5 x86. Has anyone tried hibernation under CentOS 5 x86 on a *non-virtual* machine? I tried it on my PIII and it had some kind of hibernation/resume failure. The screen went standby during hibernation and resume, and I hardware reseted the system.
