I have two ZFS servers which have several TB of space. One of the great ZFS features is the ability to send one filesystem to another filesystem, on the current or another server. I will do this over ssh. One of my servers has a lot of spare space, so I figure I will duplicate my backups there. The source This server contains a Bacula Storage Daemon with access to about 27TB, with […]

Here is a list of the jails on the two main hosts I use at home: knew I used to have a host called kraken. I created a server server, kraken-new, or knew. knew performs many tasks: runs Bacula regressions tests against various database versions hosts the backups for my Bacula server runs my home mail server on a daily basis, performs a restore of each database backup into a database to make
When I acknowledge a service problem on Nagios, I do not want to send a notification that it has been acknowledge. This patch, against Nagios 3.5.1 changes the default from CHECKED to not checked. With credit to Marc Powell for his suggestion. After that initial success, I went one step further and supplied a default comment of ‘OK’. Acknowledging a service problem is now three clicks. The full patch is here.

I realized that making strong working relationships with others who share my passion is important. Not only does this solidify the community of which you are a member, it also helps you personally. Every conference I have attended gave me a great idea for a current or upcoming project. Here are a few

I started seeing this recently. It appears in the logs on my firewall: It does not seem to be disturbing anything, other than my nerves. The classical situation is: two PCs are arguing over the same IP address. Each NIC has a unique MAC address, used at the physical network segment. We often refer to IP addresses in a computer network that uses the Internet Protocol (IP) for communication. Let’s look closely at

I’m starting to play with RabbitMQ as part of a new project. The first goal: get it installed and running. I’m going to do this in a jail running FreeBSD 9.2, but this should be the same if you running a non-jail. I installed via: pkg install rabbitmq In /usr/local/etc/rabbitmq/rabbitmq-env.conf I have the following: NODENAME=bunny@sally NOTE: change sally to the hostname you are installing on. I an doing this in a jail. In

With all of the activity surrounding the Heartbleed Bug, it was great to see so many people helping out to keep things secure. Of note was the actions of the FreeBSD team in getting out bug fixes. I have three recommendations for you: Follow a release branch (as opposed to stable). Run freebsd-update in cron Subscribe to the freebsd-security-notifications list I used to follow STABLE. Now I follow RELEASE. The ease-of upgrading via

One of the great things about FreeBSD is the poudriere tool. With it, you can create your own set of customized packages for installation on your server. Today, I will be installing packages in a FreeBSD 9.2 jail. Although I am installing in a jail, the same steps apply to any FreeBSD 9.2 host. In this post, I will cover how to deliver the packages produced by poudriere. I have already written about
