OpenBSD 4.1 bnx TCP offload patch

Contributed by belenus on Thu Sep 6 08:29:46 2007 (GMT) from the dept. The TCP offload of bnx NICs like they are build inside Dell PE 2950 servers isn't working correctly in OpenBSD 4.1 and maybe earlier versions. This results in PF rdr (-> spamd) and modulate state not working. Even though the TCP offload functionality can be disabled at jumper 21 on the Dell PE2950 serverboard you can also use the following patch between the 4.1-release and -current as of 2007/09/05 (and recompile the kernel) if you do not have direct hardware access. 41_bnx_tcp-offload.patch

New URL and scripts updated

Contributed by belenus on Mon Jul 16 17:52:49 2007 (GMT) from the dept. I moved the page from lechtermann.net to openbsd.lechtermann.net so I can put some other stuff to lechtermann.net too. While migrating stuff to the new server I also updated the undeadly.org scripts from version 1.36 to 1.44 which now allows user registration and password changes.

vnconfig -K article delayed

Contributed by belenus on Tue Jul 17 20:20:03 2007 (GMT) from the scripting dept. The article about disc encryption with vnconfig -K using hotplugd will be delayed until the release of OpenBSD 4.1 because of some improvements to vnconfig which should allow to simplify the scripts. The scripts for hotplugd will receive a small update too.

ports@: NEW games/armagetronad-dedicated

Contributed by belenus on Wed Jun 25 17:52:12 2008 (GMT) from the gaming dept. I've created an OpenBSD port of the 0.2.8 branch of the dedicated armagetronad server, version 0.2.8.2.1 and 0.3.0. As of 2007/01/29 the client of version 0.2.8.2.1 is available for download too. Download: - port - packages I hope, one day, this will make its way into the official ports tree.

advanced hotplugd usage

Contributed by belenus on Wed Jun 25 17:45:54 2008 (GMT) from the scripting dept. Let me start this article with a slightly modified first part from the official OpenBSD hotplugd manpage: The hotplugd(8) daemon monitors the hotplug(4) pseudo-device, acting on signaled events by executing the scripts attach and detach in the /etc/hotplug directory. Since the example from the manpage is already pretty good I won't go into the basics here but describe a little script modification that really helps when you need more complex detach actions. The common way of using the attach script with umass(4) devices is to read the disklabel(8) and execute the proper commands (ie. mount(8)) by the type, name and label of the device. While this works pretty good when attaching a device this can't be done when detaching since the device is already gone and the disklabel can't be read anymore. To solve this problem I let the attach script write some information (device class, device name, mountpoint, device label) to the file /etc/hotplug/hottab. When a device is detached the proper device class is selected and, right now only in case of a disk device, the hottab is read and checked (see attach/detach scirpts blow). Actually I am using a similar setup at the moment on some boxes and it seems to work without issues. Read more...

ipmi0: hw.sensors

Contributed by belenus on Mon Jul 16 09:16:21 2007 (GMT) from the scripting dept. One great thing about OpenBSD is the really good hardware support for i386 machines, even for the ipmi (=Intelligent Platform Management Interface) sensors that can be found in all new Dell servers. Having one of those servers myself I couldn't resist to try it out and it just works great. There are not too many sensors on this board, but imho some of the most important. To be able to read those sensors easily and also get some historic data I have made myself a simple shell script, run from cron, that reads the ipmi sensors every hour and outputs the data into flat files. One file containing the messages of the last 48 hours (displayed below) and an directory containing all messages that have been generated so far, for future statistical use. Once I've collected enough data I will probably make some readable statistics and graphs or something like that. We'll see. Update: 16.07.2007: With a new server come other sensors, script modified and old content deleted. Read more...
