    Setting the Kernel Parameters - SUSE LINUX

    520462
      Hello,

      I have modified the SUSE LINUX kernel parameters in the file "/etc/sysctl.conf".

      After that I did apply the kernel settings based on the command: sysctl -p"

      In order to keep the changed kernel parameters after the system boot, I have executed the following command:

      "/sbin/chkconfig boot.sysctl on"

      When I reboot the system, the system is not keeping the modified parameters. It is keep the old kernel parameters...

      Looks like the command "/sbin/chkconfig boot.sysctl on" is not working...

      Am I doing soemthing wrong here?

      Thank you,
      Nikee

          Hi Nikee,

          to test, if boot.sysctl is active on boot, you can run the command:
          $> yast runlevel
          switch to expertmode and look, if boot.sysctl is set to run at boottime.

          It will not be shown as active, but there should be a "B" in the column "B" for this entry.

            Hello Thorsten,

            As per your details, I did check the yast in the expert mode.

            Here is how it looks like...

            xboot.sysctl xNo xBx x x x x x x xrun sysctl with a given config file...

            As you said, there is B, but how come the kernel settings are not active after reboot?

            Thank you,
            Nikee

              Hi,

              did you try to set your kernel-parameters with yast, using the command
              &> yast sysconfig
              ?

              You may try this, or run
              &> /sbin/SuSEconfig
              manually after changing parameters without using YaST.

              Maybe this helps. If not, please provide us with more information, espacially:
              What are the kernel parameters, you want to have changed?
