I have a number of things I want to get done in the short term: remove the mail server on my gateway box at home and start using a mail server on an internal box Configure my external mail servers (out there on the Internet) to use TLS when talking to each other Configure those same servers to accept mail from that new internal mail server Stop using Postfix on servers which only […]
My ZFS system hits a high load average every week during its scrub.

I’m in the process of setting up a new gateway/firewall. The new hardware will be faster and have more space. At present, the old firewall is also providing DHCP and DNS services. I want to move those off the gateway and onto another server. Why? I want the gateway to run only services that are related to gateway/firewall services. That keeps things simple. At present, the new firewall has just 43 packages installed.

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services. The filesytems:
This post has been replaced by a newer one. For future reference, this is the slocum server, which I use for various jails and services:
Today I created the new gateway machine. It is a ZFS-only system with 3x3TB drives in a mirror configuration. The hardware was my old ZFS workhorse, now replaced by something with more storage. I had a moment of panic, thinking this server had just one NIC, but I was wrong. em0 will be the local 1G LAN. re0 will have to be my upstream connection. That’s pretty sad, given it’s only a 10Mb

I use FreeBSD. I’ve used it since 1998. For me, it does good stuff, reliably, and predictably. The community is very supportive and helpful. That goes a long way when choosing your open source operating system. Included within FreeBSD, since FreeBSD 4.0 in March 2000, is a great tool for separating out services and to provide a virtualization strategy: jails. Some will argue that jails are not virtualization. I contend that it’s a

A few weeks ago, I moved some Bacula Volumes from one Storage Daemon to another. In fact, I was decommissioning the old bacula-sd and creating a new one. I copied all the Volumes over. Backups have been running smoothly ever since. However. Today I tried a restore. It failed. Without any useful diagnostic information. Here is what I have: After thinking for a while, I started to wonder if this was a database

I’ve been building up a new server lately. Now I’m ready to move the tape library from the old host to thew new host. As I opened the new server to insert the existing SCSI card, I discovered that I needed a new SCSI card. It just would not fit. This is the card I was using under FreeBSD 8.4: ahc0: <Adaptec 2944 Ultra SCSI adapter> port 0xa800-0xa8ff mem 0xfb7df000-0xfb7dffff irq 20 at

I’m in the process of moving a system from one server to another. Today, I’m going to try moving a jail using ezjail-admin archive. The two systems I am copying jails between these two systems: source: FreeBSD 8.4-RELEASE destination: FreeBSD 9.1-RELEASE-p4 I really am interested to see if this works. Creating the archive Best practice is to stop the jail. You can archive a running jail, but I content that you will get
