This was done on FreeBSD 9.2-RELEASE-p10. After my boss told me about losing qmail logs from a jail some time ago when a server was shutdown, I started looking at some tests to ensure that jails are shutdown properly. I am beginning to suspect they are not. Consider this test. I added this to /usr/local/etc/rc.d/nullmailer […]

Background I was asked to comment on the following: Our software is built and maintained by about 20 engineers, and runs in production on dozens of servers in a remote data center. One problem we frequently face is identity and access management on these servers – our engineers occasionally need to directly access the servers

Earlier today, I was reminded of a old series of tweets regarding temperature. That led me to this to a FreeBSD Forums post which showed me this interesting bit of information. I draw your attention to the two hw.acpi.thermal values near the top. Those may well represent the ambient room temperature, more or less. A

I had a power failure at home tonight. The clients did not react well to the outage. They aren’t at home. They’re out there on the internets.

I have a custom patch for Nagios. I use poudriere for building my FreeBSD ports. EDIT: 2023-03-25 I have change the local for my patch files using a hook. See poudriere hooks – I am no longer using /usr/ports/distfiles/local-patches>; instead, I’m using /usr/local/etc/poudriere.d/local-patches. How can I combine the two? I asked that question on the

Last night, and again this morning, I thought my inbox was rather light. When I checked Nagios, I found out why. I saw two mail servers: nyi-vpn check_postfix_queue CRITICAL 06-10-2014 12:12:38 0d 12h 51m 40s 4/4 96 mail(s) in queue supernews-vpn check_postfix_queue CRITICAL 06-10-2014 12:11:10 0d 10h 48m 8s 4/4 124 mail(s) in queue It

Every day for weeks I’ve been seeing these entries in my logs: I could ignore them, but that’s not in my nature. I want to know why this is occurring and fix it. Attempting to find the source, I started a tcpdump on the host: That wasn’t much help. I think I should have logged
