Services Are Hard

It can be tough running software as a service. Apple Maps has had widespread downtime reported today leading to lots of people poking fun at them and their status as second to Google Maps (dozens of people were affected jokes). The other day I was driving with Maps running when the GPS lost where I was and the arrow marker started drifting off-road randomly around town. I snapped a photo at apparently the perfect moment as the marker drifted by Lost Ln. Not sure if that was a precursor to this outage, but the photo and timing seem appropriate.

OpenVPN Fails to Start on Boot – CentOS 7

This all started one chilly January morning when I upgraded my CentOS 7 virtual machine. My OpenVPN connection would fail to start because the /run/openvpn/ovpn-client.status file was not there nor the /run/openvpn directory. It took a lot of investigative work but what we found was the /usr/lib/tmpfiles.d/openvpn.conf file had this in it: d /run/openvpn-client 0710 root root – d /run/openvpn-server 0710 root root – This temp file was making the directories in the /run folder that were needed on start for OpenVPN to work. As you can see the first line is creating the /run/openvpn-client folder.

64 Bit ColdFusion with 32 Bit Open Office

If you’re running a 64 bit ColdFusion installation and want to use cfdocument to convert Word, Excel, or PowerPoint files to PDF you may encounter an issue with an incompatibility between the 64 bit dll for ColdFusion and the 32 bit dll for Open Office. Java can’t load and run them both to work together. The good news is that there is a workaround for this issue. You’re going to need to: Download the latest version of Open Office from openoffice.org to your server and install it (you can use the default locations during the installation). Download the Non Sucking Service Manager (NSSM) from┬ánssm.cc and simply save it into a convenient folder – no installation needed. You will then create […]
