Double timestamps in logs

1 Comment / FreeBSD, Open Source, syslogd / By /

I noticed some double timestamps in my logs recently. They started just after I upgraded the host to FreeBSD 12, but I am not convinced they are related. This is from /var/log/messsages: Jan 22 21:41:40 knew 1 2019-01-22T21:41:40.760533+00:00 knew.int.unixathome.org pkg 89351 – – py36-iocage-devel upgraded: 1.0.0.20181219,1 -> 1.0.0.20190122,1 They started late yesterday, this is from /var/log/maillog: Jan 21 22:28:58 knew 1 2019-01-21T22:28:58.677083+00:00 knew.int.unixathome.org postfix/anvil 42521 – – statistics: max connection rate 1/60s for […]

Upgrading to FreeBSD 12.0 from FreeBSD 11.2 using beadm and freebsd-update

Leave a Comment / beadm, FreeBSD, freebsd-update / By /

Today I will upgrade knew from FreeBSD 11.2 to FreeBSD 12.0. It so happens that this is my last server at home which is still running 11.2, but I do have another server still on 11.2, but that one is at NYI. This post isn’t so much about beadm or about freebsd-update. I have written about moving to a beadm layout, but if your zfs list output looks something like this, you’re good

Collecting statistics from bind / named

3 Comments / FreeBSD, iocage, Jails, named / By /

I use bind (Berkeley Internet Name Domain) as my DNS server. I am currently running bind 9.11.5P1 on FreeBSD 11.2-RELEASE-p8 in a jail, with iocage as my jail manager. The OS, jail, and jail manager should play no part in how this works. I have been collecting statistics from bind for some time. I have configured LibreNMS to collect the details via snmpd and they are plotted in a lovely looking graph. The

Registering FireTV – unable to receive verification code on phone

Leave a Comment / General / By /

I was setting up my FireTV (seems to be a TV with built-in FireStick functions). I was stuck, waiting for a verification code which never arrived on my phone. I was expecting an incoming text. I was wrong to expect that. I had gotten to the stage of logging in with my Amazon credentials and was getting told (and I paraphrase here): Because of the way your account is set up, your login

avoiding duplicate cronjobs

2 Comments / Shells / By /

Sometimes you want to run a cronjob on a frequent basis, but you rarely want a new one to start before the old one has finished. There is an easy tool in FreeBSD base called lockf. It is similar to the flock tool. Here is an example I am using: Based on the man page, the lockf utility acquires an exclusive lock on /tmp/.rsyncer.rsync.papers, creating it if necessary, and removing the file on

Configuring LibreNMS Nginx statistics

Leave a Comment / LibreNMS, nginx, snmp / By /

This post might help me in configuring net-snmp to deliver Nginx statistics to LibreNMS. As such, this post may not be as helpful to you as the official documentation. Key is this URL: http://127.0.0.1/nginx-status The nginx.conf file needs something like this: NOTE: the fastcgi_pass line might also be fastcgi_pass 10.80.0.92:9000 depending on what you find in /usr/local/etc/php-fpm.conf. You should see something like this in the script, which you might have copied from https://github.com/librenms/librenms-agent/blob/master/snmp/nginx

Adding a zroot pool to an existing system

Leave a Comment / beadm, Disks, File Systems, FreeBSD, hardware, HBA, ZFS / By /

Current FreeBSD versions will allow you to create a zroot zpool from which you can boot. However, when I created the main zpool for slocum (on Fri May 3 2:16 2013), that option did not exist. You might ask: how do I know that date? [dan@slocum:~] $ zfs get creation system NAME PROPERTY VALUE SOURCE system creation Fri May 3 2:16 2013 – At present, the system boots from a raidz2 zpool.

This post has been replaced by a newer one. For reference, the previous post on this server is still available. The most recent change was extracting the beadm boot environment to a new zpool, zroot. For future reference, this is the slocum server, which I use for various jails and services. It is mounted in the 4U chassis mentioned in this post The filesystems, well, some of them: And dmesg:
