Today I’m setting up snmpd on a new [to me] host. It’s a Dell R730. Previously, my documentation for this was a bit jumbled. It was written in 2015 and contains a few updates and corrections. It was hard to follow, even for me. This new post is an update of that one. See my […]

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where. In this post: knew r730-03 FreeBSD 13.2-RELEASE-p2 The data There are the zpools in question:

The vnet (network subsystem virtualization infrastructure) on FreeBSD is both a blessing and a curse. For me, it isn’t working well with IPv6. I’ve hit issues with pf (since solved, I’m sure). It’s a useful feature but can be confusing. It helps to have lots of time to think about it and what you’re doing.

I’m ready to downsize. I’m going to replace knew with r730-03. The former has 20 5TB drives. I don’t need all that space now. I’ll settle for 12TB instead. The two new drives arrived today: [23:39 r730-03 dvl ~] % grep da2 /var/run/dmesg.boot da2 at mrsas0 bus 1 scbus1 target 2 lun 0 da2: Fixed

I started using Home Assistant (HA) for graphing the power consumption of my house. Many months before venturing down that road, I bought a Greeneye Monitor (GEM). A current transformer has been installed on each circuit in my breaker box (see the photos near the bottom of this album). I chose HA for that. I

FreshPorts make use of a simple python daemon (fp_listen). It has been in use since at least 2006. It was (I think) vermaden who mentioned it (I can’t find the reference) and it triggered an idea. The role of fp_listen is to listen for backend notifications and respond accordingly. One of its primary goals is

NOTE: this problem was fixed by moving all the IP addresses to the bridge. See Changing how I use IP address with FreeBSD’s vnet – so IPv6 works I just restarted my pkg01 jail. Now Nagios can’t see it on IPv6. In fact, none of the jails on this host can now ping pkg01. This

It’s good to do automated backups. When you do that, add monitoring to make sure the backups are occurring successfully. In my case, I backup using Bacula. Each job creates a new .bsr file. I copy these files to another location each day. Then I monitor the dates on those files and they should all

Yesterday, I noticed this message in one of the “daily security run output” emails which FreeBSD host can send out. I’ve used net-mgmt/nrpe3 for several years. It checks remote hosts and runs any number of predetermined commands and returns the results. It’s stable, highly configurable, and just keeps running. I had a look at the
