security/ssl-admin for ordinary SSL/TLS services
I came across Dan Langille post on security/ssl-admin and figured I should try it before my old certificates expires later in 2016. ssl-admin exists mainly for managing OpenVPN certificates, and with some tweaking you can make it work for ordinary SSL/TLS services.

One of my MySQL 5.7.12 instances refused to start after upgrading to FreeBSD’s MySQL port version 5.7.12_1, claiming: 2016-05-18T11:03:26.688719Z 0 [ERROR] InnoDB: The Auto-extending innodb_system data file ‘/var/db/mysql/ibdata1’ is of a different size 4864 pages (rounded down to MB) than specified in the .cnf file: initial 8192 pages, max 0 (relevant if non-zero) pages! “Googling” […]

All FreeBSD systems under my care got upgraded last Friday to fix some NTP bugs. That upgrade introduced a new bug in the kernel. The bug first appeared at r298004 in base/head, and later at r298134 in base/stable/10. The i386-based systems were more notably affected than the amd64-based systems, as the former typically has less […]

I received a cute email today. It has the usual traits of bad spelling, incorrect information, and other amusements. I wonder if the ID badge is genuine, but I doubt the name matches the pictured individual. Received: from h1.flipio.ro (unknown [128.140.228.99]) by [WITHHELD] (Postfix) with ESMTP id B85CF94065; Tue, 3 May 2016 04:16:57 +0200 (CEST) […]

Brandon J. Wandersee’s recent post on the FreeBSD Questions mailling list pointed me to Matthew Fuller‘s BSD vs Linux. Enjoy! You should replace every mention of “CVS”, “CVSup”, and “pkg_*” with “Subversion” (SVN), “SVNup”, and “pkg *”, respectively. I.e., the command pkg_add becomes the command pkg add (with no underscore), etc.

Finally, KBDMUX_DFLT_KEYMAP is available for those of us using keyboard layouts different from the US/UK keyboard layout. This is very handy when running in single-user mode.

AFRINIC with only two years to go
According to Geoff Huston‘s automated predictions, today is the day where AFRINIC has only two years left before they run out of IPv4 addresses. As time progresses, AFRINIC might hit their Z day sooner. AFRINIC has a webpage of their own on the IPv4 exhaustion within AFRINIC.

I learned ZFS hides certain filesystem and pool properties from normal view. You need to know their names and specify them explicitly to get their values. Use the option -p to get the raw value of the filesystem properties. E.g. zfs get -p createtxg.

Add these three commands in the appropriate .texi file after @end titlepage. The first command selects A4 paper with better margins than the @afourpaper command. The second command turns on page headers suitable for two-sided printing (duplex printing). The third command starts the next chapter on an odd page number.
