Since I got the pleasure of watching some Windows boxen with Nagios, I took the Windows Update plugin from Michal Jankowski and implemented it. It took me some time, to initially set up the nsclient++ correctly so it just works, but up till now the check plugin sometimes reported the usual “Service Check Timed Out”. Usually I ended up increasing the cscript timeout, or the nsclient++ socket timeout, but it still kept showing up. Since I rely heavily on my surveillance tools, I have the demand, that as few as possible false positives show up. So I ended up chasing down this error today, and after that I have to say it was quite simple. ...

I was fighting with our VTL again, and TSM was thinking all the drives were offline. In order to update the drive status, you’d need to go into the ISC and select each drive and set them to ONLINE. Since I’m a bit click-lazy, I wrote a simple nested for-loop, which gives me the output to update all the drives at once: 1 2 3 4 5 for i in 1 2; do for k in $( seq -w 1 32 ); do echo "UPDATE DRIVE VTL$i VTL${i}_DR${k} ONLINE=YES" done done Result is a list like this: ...

I had this weird plugin error the other day which bothered me on Friday. I decided to go fixing it. So after poking around in the vCenter installed software list. I couldn’t find the Auto Deploy in the list, so I figured due to my recent vCenter reinstallation while keeping the database, I forgot to reinstall Auto Deploy. I went ahead and started the Auto Deploy setup from the DVD again, until I received this weird looking error. Apparently the setup thought (and decided correctly) that Auto Deploy was already installed in my vCenter. ...

Well, I recently prepared a bunch of Debian KVM guests, and today I got annoyed (basically because logwatch complains about it …) by this pesky error message on each startup. What causes this is error is really simple. Udev loads the PC speaker driver (pcspkr) and then (for whatever reason) tries to load the alsa-module for the PC speaker (snd_pcsp). And the second one, basically fails. All we need to do, is create a blacklist.conf and add the latter one to it. ...

Well, the title pretty much says what I want to do. Even if the DS213+ is on top of a living room cupboard, it’s still way to bright .. as I don’t need really need the LED, here’s a quick hack (the ID and the device is taken from the Synology Wiki) on how to disable it on each startup: 1 2 3 4 5 6 7 8 #!/bin/sh case $1 in start) echo "Disabling Power LED" echo 6 > /dev/ttyS1 ;; esac Just place the file in /opt/etc/init.d/S01leds and the script is gonna turn the LED off during a boot/reboot.

As I wrote before about enabling multipathing for the AutoYaST installation it’s about time I write this one here. Sadly AutoYaST needs a little push in the right direction (as to where to actually put the root device), so here’s part of my AutoYaST profile for such a Cisco blade: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 <profile xmlns="http://www.suse.com/1.0/yast2ns" xmlns:config="http://www.suse.com/1.0/configns"> <bootloader> <device_map config:type="list"> <device_map_entry> <firmware>hd0</firmware> <linux>/dev/sda</linux> </device_map_entry> </device_map> </bootloader> <partitioning config:type="list"> <drive> <device>/dev/sda</device> </drive> </partitioning> <scripts> <pre-scripts config:type="list"> <script> <debug config:type="boolean">false</debug> <feedback config:type="boolean">false</feedback> <filename>config-ucs.sh</filename> <interpreter>shell</interpreter> <source><![CDATA[ cat /tmp/profile/autoinst.xml | sed "s,/dev/sda,/dev/mapper/`/sbin/multipath -ll | grep dm-0 | cut -d -f1`," > /tmp/profile/modified.xml ]]> </source> </script> </pre-scripts> <chroot-scripts config:type="list"> <script> <chrooted config:type="boolean">true</chrooted> <debug config:type="boolean">true</debug> <feedback config:type="boolean">true</feedback> <filename>config-ucs-chroot.sh</filename> <interpreter>shell</interpreter> <location>http://install.home.barfoo.org/autoyast/scripts/config-ucs-chroot.sh</location> </script> </chroot-scripts> </scripts> <software> <packages config:type="list"> <package>multipath-tools</package> </packages> </software> </profile> Now, the profile addition takes care of the placement of the root-device now (simply parses multipath -ll) and adjusts the pulled profile accordingly ( /tmp/profile/modified.xml), which AutoYaST then re-reads. ...

Recently I had the issue, that my root partition (/ or slash) was a bit too small for some update. So I had to look up how to resize the root partition. Luckily with LVM/btrfs this works like a charm (if you added enough free space): 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 christian:(hans.heimdaheim.de) PWD:/ Fri Mar 11, 07:02:40 [0] > df -h Filesystem Size Used Avail Use% Mounted on udev 2.0G 4.0K 2.0G 1% /dev tmpfs 396M 428K 395M 1% /run /dev/dm-1 952M 789M 176M 82% / none 4.0K 0 4.0K 0% /sys/fs/cgroup none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm none 100M 0 100M 0% /run/user christian:(hans.heimdaheim.de) PWD:/ Fri Mar 11, 07:02:46 [0] > lvextend /dev/vg0/slash -L2G Extending logical volume slash to 2.00 GiB Logical volume slash successfully resized christian:(hans.heimdaheim.de) PWD:/ Fri Mar 11, 07:04:51 [0] > btrfs filesystem resize max / Resize '/' of 'max' christian:(hans.heimdaheim.de) PWD:/ Fri Mar 11, 07:04:55 [0] > df -h Filesystem Size Used Avail Use% Mounted on udev 2.0G 12K 2.0G 1% /dev tmpfs 396M 440K 395M 1% /run /dev/dm-1 2.0G 647M 1.4G 32% / none 4.0K 0 4.0K 0% /sys/fs/cgroup none 5.0M 0 5.0M 0% /run/lock none 2.0G 0 2.0G 0% /run/shm none 100M 0 100M 0% /run/user

Another .NET update later, an hour spent looking this up. Why is mscorsvw.exe using 25% CPU for >30 minutes? Here’s a short outliner on how to speed it up: The scripts we’ve provided are a convenience for people who don’t want to deal with a command prompt. If you prefer to use the command prompt, you can use the commands below instead. These commands depend on the version of the .NET Framework you have installed and the version of Windows that you have and whether it’s 32-bit or 64-bit. ...

Well, I’ve been tinkering with NGINX for a while at home, up till now I had a somewhat working reverse proxy setup (to access my stuff, when I’m not at home or away). What didn’t work so far was the DSM web interface. Basically, because the interface is using absolute paths in some CSS/JS includes, which fuck up the whole interface. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 <link rel="stylesheet" type="text/css" href="/scripts/ext-3/resources/css/ext-all.css?v=3211" /> <link rel="stylesheet" type="text/css" href="/scripts/ext-3/resources/css/xtheme-gray.css?v=3211" /> <link rel="stylesheet" type="text/css" href="/scripts/ext-3/ux/ux-all.css?v=3211" /> <link rel="stylesheet" type="text/css" href="resources/css/desktop.css?v=3211" /> <link rel="stylesheet" type="text/css" href="resources/css/flexcrollstyles.css?v=3211" /> ... <script type="text/javascript" src="/scripts/uistrings.cgi?lang=enu&v=3211"></script> <script type="text/javascript" src="/webfm/webUI/uistrings.cgi?lang=enu&v=3211"></script> <script type="text/javascript" src="uistrings.cgi?lang=enu&v=3211"></script> <script type="text/javascript" src="/scripts/prototype-1.6.1/prototype.js?v=3211"></script> <script type="text/javascript" src="/scripts/ext-3/adapter/ext/ext-base.js?v=3211"></script> <script type="text/javascript" src="/scripts/ext-3/ext-all.js?v=3211"></script> <script type="text/javascript" src="/scripts/ext-3/ux/ux-all.js?v=3211"></script> <script type="text/javascript" src="/scripts/scrollbar/flexcroll.js?v=3211"></script> After some googling and looking through the NGINX documentation I thought “Why don’t I create a vHost for each application that is being served by the reverse proxy?”. ...

As I said in the previous posts, I’ve reorganized my music library. That included creating sub directories based on the first letter of the artists name (say for example AC/DC would be sorted into the folder A, Iron Maiden would be sorted into I). So here’s the file name pattern, that I’ve used to accomplish this: 1 $left(%album artist%,1)\%album artist% - [%date% - ]%album%\$num(%discnumber%,1)%tracknumber%. %title%
