Tomcat 7, munin and Ubuntu 14.04

deploy, Ubuntu

Lately I had to reconfigure an Ubuntu 14.04 server.
Dealing with Tomcat 7 I’ve encountered those two situations:

Enable larger file uploads via Tomcat manager

I had a ~180 war file to deploy. Ubuntu’s Tomcat setting put a limit at 50MB. This has been solved using the tips in this post by skotfred. Unfortunately I haven’t found a more orthodox way of achieving this other than modify the /usr/share/tomcat7-admin/manager/WEB-INF/web.xml in the values max-file-size and max-request-size.

Enable Tomcat monitoring in Munin

Here I’ve followed the tips over this Serverfault discussions.
Adding a [tomcat_ *] was the key.

smcFanControl to the rescue of your iMac

Apple, Hardware, how-to

imac-2012
During the previous week I found myself trying to manage an early 2008 iMac with some serious issues booting. After having tried any trick I knew I decided myself to use the Apple’s Hardware Tests. Here I found some glitches with the fans. This mac was used in a man’s luxury tailor shop … so the outside was shiny!

Never I could ever imagine the amount of dust collected inside…

Without opening the iMac chassis I tried a first cleaning using an air-compressor. Then I remembered of smcFanControl, a software more commonly used to tame the heating of Apple’s notebooks. After the download I’ve started it and created a new cooling profile called “Cleaning” setting all the 3 fans inside the iMac to their maximum speed. Then I’ve selected it and … WOW … a cloud of dust was blown away from all the case’s fences! Incredible!

I had the iMac running this way for near twenty minutes, then made come it back to its default. Since then the iMac is working smoothly like when it was brand new. Zero euro spent, maximum result!
