Postfix has been trying to tell me something: your configuration is wrong. Most cleverly, Postfix has been emailing me about this. The first email came on 22 Oct 2014. I ignored it. The second email arrived five days later on 27 October 2014: I recall looking around, but I didn’t do anything. I think I […]

I wanted to know how many wireless access points (WAPs) were using what channels near my place. I googled and found a reference to the built-in OSX tool, Wireless Diagnostics. But to be fair, the app is hidden. To access the app, hold the Command key while clicking on the WIFI icon. This will change

I upgraded to Yosmite today. It was not without pain. I use openconnect, which in turn, uses tuntap. After upgrading, my connection attempts resulted in: Failed to open tun device: No such file or directory Set up tun device failed I was also seeing this in /var/log/system.log: Oct 28 15:39:39 snorty.example.org com.apple.kextd[19]: ERROR: invalid signature

Contrary to all the examples I found, it’s not easy to get snmpwalk to communicate with snmpd. I am using the net-mgmt/net-snmp port with the default configuration options. It was installed with: pkg install net-mgmt/net-snmp This is the minimal configuration file, which should be placed at /usr/local/etc/snmp/snmpd.conf: rocommunity public When starting snmpd for the *first*

Short version: I used this regex when restoring to a jail on the slocum server: !/\.zfs/snapshot/snapshot-for-backup/!/! Background Today I did this when setting up an ssh-key on a new host: ssh-add -L > ~/.ssh/authorized_keys Oh. That should have been >>. Restoring During the Bacula restore, I need to change this path: /usr/jails/mydev/.zfs/snapshot/snapshot-for-backup/usr/home/dan/.ssh/ to /usr/jails/mydev/usr/home/dan/.ssh/ That

In this post, I’m using bind98-9.8.8 from ports on FreeBSD 9.3, in case that helps you. Today, I was adjusting the pgcon.org domain as part of the move from the old server to the new server. This move would also see the website updated to PGCon 2015 and the use of Ansible for configuring that

For future reference. This server formed the backbone of just about everything I did. It hosted about 13 domains. Sadly, it was i386 and would not do for ZFS.

After a lengthy Twitter discussion this afternoon, and a post to the forums, I decided to alter my ezjail basejail. The issue: when you update the basejail, /etc/rc.d and /etc/periodic do not get updated. This is by design. I wanted those directories to get updated. So I have changed the basejail. I will outline first,

I’m doing some work with logstash-forwarder as part of a consolidation effort to get all the logs into one place, and using logstash to put them into Elasticsearch. logstash-fowarder requires the Go programming language, and that will be our first step. Installing go, the programming language I am assuming you are installing go at /usr/local;
