Deploying Epson EasyMP Multi PC Projection for Mac

When adding Epson EasyMP Multi PC Projection 2.1.0 to Munki, I found that the built-in postinstall script fails. Some digging revealed that the script was expecting a file to exist at </tmp/mpp-72B3FDFF-9513-4CED-96C3-34881FC77AB8>. It reads that file and uses the value contained for the “ClientMode” preference in </Library/Preferences/com.epson.EasyMP_Multi_PC_Projection.Settings/mppsettings.xml> On a successful install the the GUI, that… Continue reading Deploying Epson EasyMP Multi PC Projection for Mac

Using SSH Keys for Passwordless Authentication

From my experience with Apache I assumed that PHP scripts would be executed by the same user the web server is running as — ‘nginx’ in this case. But this could no longer be taken for granted since php-fpm is a separate… Continue reading File ownership considerations with Nginx and php-fpm

Scheduling Reboot of Motorola Cable Modem

UPDATE: This no longer works for me because a recent firmware update removed the Restart command from the web interface. Periodically my Motorola SURFboard SB6141 cable modem stops talking to the outside world. I don’t know why, but restarting the modem fixes it every time. Rather than having to regularly power-cycle it by hand – or, heaven forbid, buy new hardware… Continue reading Scheduling Reboot of Motorola Cable Modem

Using Configuration Profiles to Enable iOS Printing to CUPS Servers
