Wednesday, May 14. 2008Debian - Dell OMSA SNMP
If you would like to use SNMP to monitor your dell server with OMSA (server administrator) installed, you have to configure your local SNMPd.
First you have to enable SNMP on OMSA: /etc/init.d/dataeng enablesnmpThan restart your Data Engine System from OMSA: /etc/init.d/dataeng restartYou can now install the snmp daemon from debian: apt-get install snmpdSNMPd should listen to all interfaces. You can configure this at /etc/default/snmpd Please note, that you have to remove the entry -I -smux, because OMSA uses snmp smux for communicating with the SNMP daemon. The following snmpd.conf is tested to work with OMSA: com2sec local localhost publicNow restart the snmpd and install also the dell mibs. You can find the mibs in /opt/dell/. After the restart you can walk throw your SNMP tables: snmpwalk -v2c -c public localhost 1.3.6.1.4.1.674.10893If you want to monitor the health of your server I can suggest you the following nagios plugin: check_omsa_snmp.pl - this plugin checks temperature,voltage, Power Supply and Cooling Devices Thursday, November 15. 2007Clamav daemon on etch - long startup time
If you are running clamav daemon on debian etch, and your clamav daemon takes up to 3-4 minutes to create the unix socket and the pid file, don't despair it's an clamav bug.
While you are running clamav with amavis this bug can be very annoying: amavis[22480]: (21470-02) (!!) ClamAV-clamd av-scanner FAILED: Too many retries to talk to /var/run/clamav/clamd.ctl (Can't connect to UNIX socket If you strace your clamv on the startup time you get many of these messages: read(10, "n.Downloader-14249\n29184:5d2a569"..., 4096) = 4096 The clamav version is debian etch is 0.90.1. The bug is fixed in version 0.91rc2. So you could use the backports.org packages (0.91.2). Wednesday, October 17. 2007Updated 3dm2 and CLI packages from 3Ware
I have updated my 3Ware 3dm2 and 3Ware CLI debian packages. I also included the patch from tretkowski.de.

If you update from sarge to etch with an running 3dm2, please make sure if you use the default etch kernel (version 2.6.18) that you have installed the newest version of 3dm2.
If you use an old 3dm2 version with the etch kernel you get the following messages in dmesg: 3w-xxxx: SCSI_IOCTL_SEND_COMMAND deprecated, please update your 3ware tools. You can get the newest version of 3dm2 here. Sunday, June 3. 20073Ware - CLI - Command Line Interface for debian

If you get this "4gb seg fixup" message on tty and/or in your /var/log/messages after the reboot to the Xen Hypervisor on Etch, you should check if you installed libc6-xen on your system.
If not, install it, and reboot the system again. Thursday, January 11. 2007Using tw_cli from 3Ware
The tw_cli from 3Ware for all the 3WARE Controllers is a little bit tricky.
Here are some examples how to use tw_cli:
The info command is usefull for checking how many controller are available.
The /c0 show command display which raid units and disks avilable on controller 0. For the second controller in the system please type /c1 show.
The /c0/u0 start verify command starts an Raid verify on Controller 0 Unit 0.
The command /c0/u0 start rebuild disk=1 starts the rebuild on controller 0, unit 0 and disk 1 (on port 1). If you are using debian, you can use my debian packages, please see here! Sunday, January 7. 20073Ware CLI and 3dm2 debian packages updated
I have updated my 3Ware CLI (Command Line Interface) and 3DM2 (Disk Management Utility) debian packages.
You can find it on my website like the last version. Please note, I have only updated the i386 packages, the amd64 will follow in some days. Wednesday, October 4. 2006snmpd in debian - say no to the drugs
Using /etc/defaults/snmpd in debian:
grep "SNMPDOPTS" /etc/default/snmpd | cut -f 2 -d '-' Say no to the drugs Wednesday, August 2. 2006Devolo dLAN linux driver
Devolo dLAN USB drivers for the devolo network over power module.
If you try to compile the version 2.0 on an higher kernel than 2.6.13 you get the following error:

3Ware Software the second round!
I have created debian packages for the CLI (Command Line Interface) for 3Ware Controllers. You can find it, like the 3dm2 on Debian Unofficial and here. Saturday, June 3. 20063Ware - 3DM 2 - Disk Management Utility for debian
I have created debian packages for the 3DM 2 (Disk Management Utility) for 3Ware Controllers.
You can find it on Debian Unofficial and here. Friday, May 19. 2006Debian Volatile Service
Relating to that Virus Scanning entry I think Debian Volatile is better for an up-to-date ClamAV than Backports.org.
Debian Volatile is made for packages that change very often, and you need the current upstream package on a server. Like an up-to-date virus scanning engine. So simple and this line to your sources.list and run after that an apt-get update. deb http://ftp2.de.debian.org/debian-volatile sarge/volatile main BTW: Volatile Mirror List Now you can install your clamav normally with an apt-get install clamav.
