Creating a FreeBSD jail to run DHCP and DNS

Leave a Comment / DHCP, DNS, FreeBSD, Open Source / By /

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. […]

Dynamic DNS solutions: what have you used?

1 Comment / DNS / By /

I’m looking for a dynamic DNS solution. When connected to my home network, my laptop gets a static IP address. When it connects via OpenVPN, it gets a different IP address. I’d like the hostname updated to reflect the last used IP address. I run my own DNS servers at home, and all my hosts are in there. I am not sure that something like noip.com is what I want. I use that

The new gateway configuration

Leave a Comment / FreeBSD / By /

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

Using Bacula in a jail

Leave a Comment / Bacula, ezjail, FreeBSD, FreshPorts, Jails, Open Source / By /

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

Moving Bacula Volumes from one Storage to Another

Leave a Comment / Bacula, FreeBSD, Open Source, PostgreSQL / By /

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

nagios check for Bacula Pool volumes

Leave a Comment / Bacula, Nagios, Open Source / By /

I’m thinking about a Nagios check to let me know the status of various Bacula pools. As in, how many volumes are left, versus the maximum number of volumes permitted in this pool. Here is the bconsole command I would use: And here’s the command line bit which might work: I’ll ponder this a bit longer, and decide if I really want this monitored.
