Setting up a local subversion repository server with nil security

Leave a Comment / FreeBSD, Open Source, subversion / By /

There is much code for FreshPorts which lives in a subversion repository in my basement. I have long wanted to convert that to git and move it to git hub. In this post: FreeBSD 14.1 subversion 1.14.4 Which reminds me: I need to find a tool which backs up Github repos for me. Preferably everything under an organization. Just in case. I will copy the data from my repo to another host and […]

kernel: swap_pager: cannot allocate bio

This morning, I saw this in my logs: In this post: FreeBSD 14.1 r730-03 Looking in he logs, there wasn’t much useful: Searching online, I found swap_pager: cannot allocate bio so I decided to limit ARC size. I’ve done this before, and recently too.. Here is what I added to /boot/loader.conf: I just picked the same value I was using for another host. The values in the file can using units, such as

Loading up an old copy of a PostgreSQL database, zfs snapshots, and sanoid snapshot management

Leave a Comment / FreeBSD, Open Source, PostgreSQL, sanoid, snapshots, ZFS / By /

Sometimes you want to go back to a known good state. And you want to do it quickly, without waiting around. In my case, that’s going to be a zfs snapshot. Today I am preparing to test some code changes so that FreshPorts properly creates a new category. See these recent blog posts for details: Welcome to the new category: filesystems Fixing the category creation code In this post: FreeBSD 14.1-RELEASE-p5 postgresql16-server-16.4 dbclone

zfs hold / release

Let’s talk about zfs hold. Based on man zfs-hold: “If a hold exists on a snapshot, attempts to destroy that snapshot by using the zfs destroy command return EBUSY.” Let’s apply that to some FreshPorts snapshots which I don’t want going away: This is your typical FreshPorts website: [15:03 dvl-nginx01 dvl ~] % zfs list NAME USED AVAIL REFER MOUNTPOINT data02 1.13T 565G 96K none data02/freshports 671G 565G 88K none data02/freshports/jailed 326G 565G

Self-hosting Bitwarden / VaultWarden on FreeBSD

6 Comments / FreeBSD, Jails, Open Source, Security, VaultWarden / By /

The time has come for me to consider another application for my TOTP data (think 6-digit codes produced by Google Authenticator or an RSA device. I’ve been using an app called 2STP – I have long liked it. Support for it ended about 7 years ago, yet it continued to slug along on my phone and on my watch. Recently, it stopped working on my watch. That was the tipping point. I decided

fail2ban – adding to my website to deter abuse

Leave a Comment / fail2ban, FreeBSD, Open Source, pf / By /

The type of abuse recently seen on FreshPorts isn’t a big deal. I would ignore it if it was on my own server. However, I’m using a “paid” service and the credits go faster when pillocks do pillocky stuff. While I hope I’ve covered what I’ve done, I’ve been sick with a cold for a week, and helping to look after two < 4 year-olds for two weekends in a row. Perhaps I've

What’s this gap in the graphs?

Leave a Comment / Backups, Bacula, FreeBSD / By /

I was checking email this (Friday Jul 19, 2024) morning, over coffee, while many IT folks dealt with Cloudstrike fallout, when I noticed this message from the logs: Jul 19 09:12:18 zuul kernel: [zone: pf states] PF states limit reached I’ve seen that message before. It’s not of high concern. That server contains many services including PGCon, the former BSDCan website, and my blogs. I didn’t give it much concern, although I should

Where’s my backup?

Leave a Comment / Backups, FreeBSD, Open Source / By /

Nagios was telling me: FILE_AGE WARNING: /usr/home/rsyncer/backups/aws-1/postgresql/freshports.org.dump is 117636 seconds old and 3608113799 bytes That means the FreshPorts backup is more than a day old, and it should have been refreshed by now. OK, let’s go look. I log into the host known as aws-1 and check the files. They look fresh to me: [rsyncer@aws-1 ~/backups/database-backup/postgresql]$ ls -lt total 3525154 -rw-r–r– 1 rsyncer rsyncer 3963 Jul 16 02:14 globals.sql drwxr-xr-x 2 rsyncer rsyncer
