Storage networking is different

Herbert — Thu, 26 Aug 2010 08:13:04 +0000

Storage is, well, permanent. If there’s an undetected error in your application session, your program might crash; if the incorrect data is written to a disk, it stays there indefinitely.

Upgrading to a newer Version of Ubuntu

Herbert — Fri, 24 Apr 2009 12:55:06 +0000

Based on the fact, that Ubuntu 9.04 was announced today, it is a good idea to explain how to upgrade every Ubuntu Version using the command line.

sudo apt-get install update-manager-core
verify /etc/update-manager/release-upgrades
to use LTS or Normal based on your preferences
sudo do-release-upgrade

After that, follow the messages on the screen to upgrade your system to the newest Ubuntu Version.

Cacti: Passwords do not match, please retype.

Herbert — Fri, 24 Apr 2009 12:47:51 +0000

With the message “Error: Passwords do not match, please retype.” Cacti tried to make my life horrible today, but not with me.

If you are running Cacti 0.8.7b (which is the standard version located in the Ubuntu repositories) you will be prompted with this error after editing a host using Firefox 3. The error is based on an auto complete bug within the form. There are two solutions to avoid the problem (which worked for me):

Before saving all the settings you have to delete (if not in use) the value in the password field of the SNMPv3 settings and than switch back to your preferred method of fetching information.
Apply the patch which was provided by RichardBronosky in the Cacti Forum solving the problem.

The easiest way to apply this patch is to cd to your cacti directory and:
1. THIS IS IMPORTANT. Verify the validity of the URI like this:

Code:
curl -L http://forums.cacti.net/download.php?id=14681

2. If it looks like a safe patch, then apply it directly from that URI via curl:

Code:
curl -L http://forums.cacti.net/download.php?id=14681|patch -p1 -N

Format more than 32GB hard disks as FAT32

Herbert — Wed, 22 Apr 2009 13:30:00 +0000

There is one very annoying limitation (ok perhaps more) if you are using Windows XP. The limitation that the MS Windows XPs format tool can only handle HDDs under 32 GB of disk space. Other OS’s like Linux or Mac OS X do not have this limitations but what to do if you want to format a disk bigger than 32GB using Windows XP?

Grab one of the most useful 3rd party applications – called FAT 32 Formatter.

Using DomainKey and Sender ID as an end user

Herbert — Mon, 06 Apr 2009 14:49:00 +0000

Most implementations for using DomainKeys (or DKIM) and Sender ID are written and used on the level of the MTA to verify the authenticity of the message.

Now iconix has written a piece of software which allows the verification at end-user-level. That allows them to bring the whole process and system behind DomainKeys, DKIM, Sender IDs, SPF and so on from the MTA level to the end-user and in this case allows a broader mass to use the feature.

The tool has still some hick-hacks but its working quite well and the developers trying to fix problems as fast as possible. There are a lot of implementations available at the moment, for different mail programs as well as webmail systems.

If you wanna use one of the above features in your mail environment please don’t hesitate to ask the internet or drop me a message, especially if you are also one of these guys trying to give SPAM no chance. And most important, if you are using one of the incredible Ironport C-Series machines, setting up DomainKeys or DKIM verification is only a few clicks away

AAA with TACACS+ on Cisco IOS

Herbert — Mon, 06 Apr 2009 08:54:00 +0000

Thanks to Karsten Iwen of Security-Planet.de who wrote a very good introduction about how to set up and configure AAA with the TACACS+ Service on Cisco IOS based devices.

The how-to is in German what is normally is really hard to find in the internet, English ones are really easy to get.

Have fun with the mentioned how-to AAA mit TACACS+ im Cisco IOS.
