My laptop’s hostname is dent. I want my DNS records to point to that laptop whether I’m connected to my LAN directly (via WIFI or ethernet cable) or via OpenVPN (my VPN of choice). SIDE NOTE: You will see references to nsupdate -k below. Note that in recent versions of this program, the option you want has changed to nsupdate -y. You will find an example of the new format later in this […]

For some time, I’ve seen these messages and been slightly bothered by them. Today, I found the solution. can’t re-use a leaf (geom_label)! can’t re-use a leaf (geom_part_gpt)! module_register: module g_label already exists! Module g_label failed to register: 17 module_register: module g_part_gpt already exists! Module g_part_gpt failed to register: 17 Those messages appeared on the console while booting and were logged in /var/log/dmesg.boot. I was told, but I forget where, that this was

FreeBSD now has zl4 compression for ZFS. But you must upgrade your pools to get it. If you try before upgrading, you’ll get: # zfs create -o recordsize=8k -o primarycache=metadata -o compress=lz4 system/usr/home/dan/pgsqlsql cannot create ‘system/usr/home/dan/pgsql’: pool must be upgraded to set this property or value So, let’s upgrade: # zpool upgrade -a This system supports ZFS pool feature flags. Successfully upgraded ‘system’ from version 28 to feature flags. Enabled the following features

I found a problem with the check_pgsql Nagios plugin last week. It can’t handle names such as freshports.org. It’s a valid database name, as witnessed here: $ psql -l | grep freshports freshports.old | dan | SQL_ASCII | C | C | freshports.org | dan | SQL_ASCII | C | C | But it doesn’t work: $ /usr/local/libexec/nagios/check_pgsql -H slocum -l www -d freshports.org check_pgsql: Database name is not valid – freshports.org Usage:

In my work on FreshPorts, I’ve learned more than the average non-committer about the FreeBSD ports tree and its oddities. Just about everything learns about a port it gets from ‘make -V’. Even this method can be fraught with difficulty. In an attempt to get the fairest information possible, FreshPorts uses a chroot solution, first proposed by Ryan Steinmetz . Previous posts about this particular solution can be found in the FreshPorts blog.

I’ve been meeting a few challenges with running an instance of bacula-fd in each of my jails. Most of them are related to networking. Perhaps my deployment strategies are imposing too many restrictions. The challenges arise on the jail hosts which are not behind my firewall at home. Each of those servers is accessible through a VPN, but the individual jails on those servers are not. The backup of the jail host is
