Upgrading to a newer Version of Ubuntu
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.
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=146812. 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
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.
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
