SSL client vs server certificates and bacula-fd

See also OpenVPN: unsupported certificate purpose. NOTES NOTE: When using ssl-admin for Bacula: use option 4 (Perform a one-step request/sign) for clients (bacula-fd) use option S (Create new Signed Server certificate) for servers (bacula-sd and bacula-dir) I know these things, but I repeatedly go to option 4 and forget….

patching your Intel CPU Microcode using FreeBSD ports

Today this Nagios alert showed up: I admit it. I have not patched my micro code before. I’m doing it only because it turned up in Nagios. Browsing to that URL, I found “Starting with version 1.26, the devcpu-data port/package includes updates and mitigations for the following technical and security advisories (depending on CPU model).”.

zpool degraded – one drive missing from system

I rebooted knew yesterday for upgrades. When it came back, the main storage zpool was degraded: Is the drive alive? The drive is not listed at all in /var/run/dmesg.boot. I keep a list of the expected drives in /etc/periodic.conf, for use by a Nagios check: [dan@knew:~] $ /usr/sbin/sysrc -nf /etc/periodic.conf daily_status_smart_devices /dev/da22 /dev/da21 /dev/da20 /dev/da19

slocum

This post has been replaced by a new one. For reference, the previous post on this server is still available. FYI, this server is named after Joshua Slocum, who was the first person to sail single-handedly around the world. This server was upgraded on Feb 2 2019. Only the storage persisted. Everything else was upgraded.

zfstools & sanoid – snapshots on the local host

I’m going to implement zfstools on all my ZFS-based hosts today. I first started using this tool in July 2019. In this post: FreeBSD 12.0 and 12.1 zfstools 0.3.6_1 sanoid-2.0.1_2 Local snapshots only I will be using zfstool only for creating local snapshots. If I wanted snapshots for sending to other hosts, I would probably
