In the enterprise, SNMP is by far the preferred method for real-time alerts, failing that email. The syslog is primarily for auditing and post-mortem purposes. If the syslog was really so central in enterprise real-time monitoring of Linux systems, it's difficult to understand why popular monitoring tools typically provide an email option, very often also an SNMP MIB, but usually no plain syslog option.

Which distro were you running? Maybe it was a better option for you. I'm curious though, how did you manage to receive the various systems alerts and messages without a local MTA? Did you write your own /usr/sbin/sendmail to drop the text directly into the filesystem? > But more to the point while I *can* configure Postfix, the > installation process should configure the mail forwarder. As it does too, it just assumes that no forwarding is necessary and that the enterprise admin person with a central mailserver will probably be capable of using vi to correct the single line in /etc/postfix/main.cf. It's hardly worth writing up a YaST2 module for. >> Anton, I think I'm going to say "troll".

Having done roughly the same for the last 25 years, I submit that the syslog is primarily for auditing and post-mortem purposes, and that SNMP (and/or similar) is certainly the real-time alert mechanism of choice where many Linux systems are involved. /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] SMART daemon question

I have to ask, even though I know the probable answer: I am getting the following log messages on a machine running 11.0. The disk is a IDE disk. Could there be any software issues that cause this message to be given when it should not? Could I have something configured wrong? Or should I trust that a disk is becoming an ex-disk?

I knew it was possible, but not right out of the box. As said in one of the documents you reference: "GRUB has support for LVM and RAID since version __1.95__. Multiple volume groups don't work with GRUB 1.95 however. etc etc" The grub version on the dvd, and on repo's on the OBS is _0.97-82_ So Root within lvm no problem, but _B_oot within lvm needs the next generation-grub. In the referenced article on rocklinux they still wrote: Partition Layout The partition layout in the example will be the following: * Partition 1: 100 MB ext2 - will contain the pre-system and marked bootable. * Partition 2: rest of the disk, LVM Physical volume. So /boot is here also outside lvm. Perhaps this can be a trigger to get grub2 (tng) inside openSUSE hw -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] KDE 3.5 brain teaser - howto delete colors from *Custom Colors*
by David C. Rankin 31 Oct '08

31 Oct '08

Listmates, Here is an off-the-wall KDE 3.5 config question. In KDE apps where you use the color dialog like control center or color chooser, etc... you have the option of adding the selected color to your palate of "*Custom Colors*" so the color is available for later use. How do you remove a color from the list of *Custom Colors* ? Where is that list kept? I've grepped around in ~/.kde/share/config and /opt/kde3/share/config without luck. Where is that list hiding? -- David C. Rankin, J.D., P.E.

[opensuse] General Graphics Slowness after kernel update to 2.6.25.18-0.2-default
by David C. Rankin 31 Oct '08

31 Oct '08

Listmates, After the install of the latest kernel update for 11.0 2.6.25.18-0.2-default, I'm noticing a general sluggishness most apparent with graphics performance of my ATI card. fglrx 8.53.4 is in use an there are no errors in /var/log/Xorg.0.log. The most noticeable difference is in glxgears frame rates. Prior to the kernel update, I was getting 950 FPS without compiz enabled, and about 2600 FPS with compiz enabled. Now the frame rate is stuck at 950 FPS regardless. Nothing else has changed with my configuration other than loading the new kernel. To me it looks like the kernel handling of either glx or aiglx has changed in the 2.6.25.18-0.2 kernel that is really causing the graphics performance to suffer. I can't put my finger on anything more specific. Does anyone else have any ideas? -- David C. Rankin, J.D., P.E.

[opensuse] ffmpeg audio error mov2flv
by drek 30 Oct '08

30 Oct '08

Hi all, Before I subscribe to the ffmpeg mailing list, I ask my question here... When I want to convert a .mov movie (taken with my digital camera) into a .flv flash movie, I get the following error: Audio resampler only works with 16 bits per sample, patch welcome. I use ffmpeg 0.4.9.15594svn-20081010.pm.2143-i686 from Packman with openSUSE 11.0 (KDE4 32 bit). Below is my input and the output. The input audio contains "s16". I don't know what that means, but from google I understand that ffmpeg is probably broken because of this "s16". YaST only provides this installed version of ffmpeg. Does someone know a solution for this error?

[opensuse] Non-destructive Increase of /boot partition?
by Hylton Conacher (ZR1HPC) 30 Oct '08

30 Oct '08

Hi, Setting up a low usage 'server' to handle email, files, faxing and printing using openSUSE 11.0. I have 3 HDD's and hence would like to establish RAID 5 where possible. All disks have space for both a /boot and swap partition but this was only mounted on the first drive. The three HDD's are each partitioned the same that have had the /root and /home file systems added to software RAID 5 (md0 and md1) I tried to include the /boot partition under RAID 5 and also under ) across all three drives and when I tried to add /boot to RAID it complained/agreed but then the system would not boot so hence the boot partition has not been RAID'd. I decided to just have a single partition of 23.5MB as my /boot partition on one of the drives. System has loaded fine after install and has been working 100%. The /boot partition is 23.5MB in size. The problem is that I have been catching up on updates since 11.0 was released and currently all have been successful. Only the kernel-pae update is failing due to space constraints ie the partition needs enlarging. Is it possible to use opensuse 11 software installed via YAST ie no hand compiling, to increase the size of the /boot partition, NON-DESTRUCTIVELY ie without reinstalling the whole system again? What size should I make /boot, especially as I thought it would only be accessed on system boot? Would 100MB be sufficent and can this be done NON-destructively? I have looked at the openSUSE archive but didn't find anything there, nor on Google but YMMV. I'd appreciate a pointer or three in the right direction w.r.t Linux non-restructive partitioning, if possible.
