Reproducing a batch insert for Bacula on PostgreSQL

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

This work from August 2022 was interesting at the time. My database server gets slow from time to time. It seems to happen repeatedly. I’m not sure why, but inserting large numbers of rows takes a very long time. This is a typical use-case for Bacula when recording what was backed up. I started with this, the duplication of the batch table created when Bacula is storing attribute for later insertion into the […]

Creating jails in a jail for testing /etc/jail.conf

Leave a Comment / Jails / By /

This is work from April 2021, and sometimes there is a need to do a jail in a jail. This shows how. I want to testing jail.conf, in a jail. I don’t want to test this on a host, because that might interfere with existing jails. This is related to a FreeBSD code review which will add support for jail.d – that means you can have something like /etc/jail.d.conf/foo.conf which is the configuration

New vuln is out – where do I have that installed? – SamDrucker

Leave a Comment / SamDrucker, Security / By /

I abandoned this post back in March h202 because I was unable to get keycloak to contact samducker. I’m publishing it now mostly because of SamDrucker. keycloak is a vnet jail. Interesting things happen there. From time to time, security issues are found within software. The FreeBSD package management system relies upon pkg-audit and the Vulnerability database to alert system administrators that attention is required. Case in point, My Nagios monitoring is showing

I wrote this back when and left it in drafts. Time to publishh. I was getting this message when one of my MacBooks was trying to back via TimeMachine to my FreeBSD ZFS server. “The backup disk image … sparsebundle could not be accessed (error 19)” imeMachine also told me the last backup was on Oct 7. Checking my snapshots: [20:01 r730-03 dvl ~] % zfs list -r -t snapshot data01/timemachine/dvl-air01 NAME USED

Eaton 5PX removes power every 24 hours

Leave a Comment / Eaton, UPS / By /

When I powered on my UPS yesterday, I predicted when it would power off: 24 hours later. To be clear, it’s removing power from the outlets and not sending any notifications to the hosts that it’s about to do so. Today, I captured the console when resetting and trying to power on the UPS. The reset This is the reset output: At this point, I waited. With no more output for 3+ minutes,

Let’s find the dead cell in my Eaton 5PX

Leave a Comment / Eaton, UPS / By /

Todays goals: pull both the ups and the external battery unit (EBU). While there, swap them so the UPS is on top. Take photos of the wiring. Disconnect each battery. Measure it. Replace anything not like the others. Expecting 13V or so on most. One should read way less. Maybe. But the UPS is now charged to 100% All cells in the UPS measure about 13.4V. Next, the EBU. All aboutt 13.4 or

Complete network shutdown – wtf?

Leave a Comment / Eaton, General, nut, UPS / By /

This afternoon, I was running an Ansible script to update the snmpd configuration settings on nagios03 (which replaced nagios02 – which was intentionally destroyed earlier today). After the script completed, I could not access the ngaios3 website, nor could I ssh into the host. My first thoughts: I must have messed up the ssh configuration, I’ll fix it through the console. I can’t get to anything. Anywhere. WIFI now? No, it’s me that’s

Eaton 5PX console booting screen shots

Leave a Comment / Eaton, UPS / By /

This post shows my screenshots from the console of my Eaton 5PX as it was powered on. In this post: Eaton 5PX 2200 I was trying to clear the Replace Battery warning on my UPS after recently replacing the batteries. At present, the warning message has been cleared, I’m not sure how or why. Before taking these screen shots, the server connected to the UPS was not loading up the driver. This was
