VMWare GSX Server and CentOS
by Joshua Gimer 15 Jan '07

15 Jan '07

Has anyone had experience (good or bad) with VMWare GSX Server running CentOS as a VM under high load? Here is the situation. We are planning on rolling out some new boxes to replace an existing box. Currently this box (Sun V860) is running web services, database services, mail for students, and is an instructional box for compiling code, and web scripting among other things. We are planning on doing one of two things, either using VMWare and splitting up the services or using Solaris Zones. The box(s) has to be able to access data stored on the SAN (Fiber Channel HBA's). The boxes(VM's), or Zones would be split up accordingly: Database box: Oracle, Postgres, and MySQL Mail: Sendmail, POPS, and IMAPS (roughly 25,000 mailboxes) Web: Apache, PHP, mod_ssl Interactive Logins: Compilers and such. Any information about any experiences with VMWare and CentOS, under similar load would be helpful. I will probably make this same post on the Sun Solaris Mailing List, and VMWare's forums. Thanks in advance! -- Thx Joshua Gimer

Gnome-terminal $PATH
by Jordi Espasa Clofent 14 Jan '07

14 Jan '07

Hi all, Usually I work in X environment (XCFE) with extensive use of x terminal; concretely, I use Gnome-terminal. Sometimes I change to root to do some admin tasks. But often it seems a few commands are not availables. The key is in the $PATH value: echo $PATH (in login shell, interactive ): /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/local/sbin:/sbin:/bin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/root/bin echo $PATH (in gnome-terminal, no-login interactive shell): /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/jordi/bin The last path in $PATH variable shows me that the problem would be the gnome-terminal doesn't update correclty the $PATH when I change to root through "su" command. ¿What do you think about? TIA.

Ignoring DDC settings on Xorg
by first last 14 Jan '07

14 Jan '07

I am trying to set up a new 1400x900 widescreen monitor, but I just cannot get it to work correctly. The closest I get is 1400x900, which causes lots of vertical blur bands. I have tried with two different machines with i945 and ATi cards, running CentOS 4 and Ubuntu, always with the same result. My investigations indicate that the monitor reports itself to be "1440x900". It also supports 1600x1200 by squashing the pixels together, so it also advertises support for that resolution, which messes things up. According to the documentation I have seen online, disabling DDC (using NoDDC and DCC "off") and setting the correct modeline should work, but it always reverts to 1440x900 (if I am lucky). Any ideas on how to force it to the right resolution? It really is driving me nuts not being able to use the monitor to the native resolution.

If you use the vnc server built into X.org you have access even without a logged-in session and I find performance better than using Vino. I just recently set it up on a CentOS 4.4 workstation so I know it works with X.org in that version at least. The following page gives info on how to do it... http://gentoo-wiki.com/HOWTO_Use_VNC_to_connect_to_existing_X_Sessions The important section is the following... File: /etc/X11/xorg.conf Section "Module" Load "vnc" Load "freetype" Load "type1" Section "Screen" #This tells X where to locate the VNC password file Option "PasswordFile" "/home/your_user_name/.vnc/passwd" Section "Files" ModulePath "/usr/lib/modules/extensions" ModulePath "/usr/lib/xorg/modules" Save your changes and close your editor. You will have to restart X (no need to reboot, just log out (end session in KDE), and hit CTRL-ALT-BACKSPACE when the login window comes back up, then login). You also need to create your passwd file that you specified above. Code: ~/.vnc/passwd file $ mkdir ~/.vnc $ vncpasswd ~/.vnc/passwd Password: Verify: Regards, Paul

Problem with rpmbuild
by Todd Cary 14 Jan '07

14 Jan '07

I want to be able to recompile php, so I downloaded the src dvd and did a rpm -i php-4.3.9-3.15.src.rpm After doing that I wanted to check to see if I can recompile it before making changes. So, I went to the SPECS dir and did a rpmbuild -i php.spec It spent a lot of time doing the compile, but at the end there were errors. What am I missing?

dumb question: Need to update my GD to include freetype support on CentOS 4.4
by Dale 14 Jan '07

14 Jan '07

Hello, Sorry for what might be a dumb question. I have a CentOS 4.4 machine with GD installed. I tend to prefer doing things via RPM to allow for updating in a easier fashion. I have a php based app that requires Freetype support in GD. This is a live server with many websites on it (although none are using GD at the moment. I am not sure the best/easiest way to get GD updated such that it has Freetype support. I did not install X on this machine as it was not needed. Would installing X be one of the steps I need to take? Thanks for your suggestions. Dale

Switching from Vesa driver to video adapter driver fails
by Edward Diener 14 Jan '07

14 Jan '07

The Vesa driver works fine with CentOS 4.4. I have an NVidia 6200 video adapter. I go to Applications | System Settings | Display | Hardware tab and find my video adapter in the list and set it. The dialog tells me I have to log out for it to take effect, so I duly do that. I then getting a message from a non-graphics screen saying that the attempt to switch to the video adapter failed. When I view why, amidst all the information given is the messages: (EE) No devices detected. Fatal server error: No screens found I am able to switch back to the Vesa driver through the non-graphics screen, and this brings me back to my graphics login and I am once again successfully in CentOS 4.4 using the Vesa driver. Does anybody have any idea what the messages above mean or how I can correct it so it can successfully load my video adapter specific settings ? The NVidia 6200 is definitely on the Hardware tab menu, that is my video adapter, and I have the latest Xorg updates for CentOS 4.4.
