Installing Alfresco (3.x, 4.x) on (32bit) Ubuntu

Recently I got into a twitter discussion about installing Alfresco Community on 32bit Ubuntu. Alfresco only provides 64bit installers these days (all-in-one), and the Tomcat distribution is no more. Since Alfresco is a Java app, the app doesn’t matter. It is Java and the helper applications needed, that need to be 32/64bit.

This blog will show you step by step how to install Alfresco and the helper apps on 32bit Ubuntu 11.10 (server). It will use OpenJDK (since it is the default in Ubuntu 11.10), LibreOffice (default in Ubuntu repositories) and MySQL (because I am more familiar with than Postgress). On the way we will install ImageMagick, Pdf2swf and FFmpeg. Continue reading ‘Installing Alfresco (3.x, 4.x) on (32bit) Ubuntu’

Giplet rocks! IP numbers at your fingertips

A few weeks ago I switched Windows for Linux (Ubuntu, 10.04LTS) on my business laptop. Happy ever since! Today I am preparing a VM for a training, and needed to know some IP addresses. I ran into Giplet, a Gnome panel applet that can display IP addresses of network interfaces of choice. Continue reading ‘Giplet rocks! IP numbers at your fingertips’

DRAFT: Ephesoft on Ubuntu Linux

Ephesoft is the ‘open source mailroom automation’ tool. The Community Edition comes with a full blown Windows installer, but being open source minded, and given the fact that it is a Java Web application depeding on some helper applications (like Tesseract, ImageMagick and hOCR), this should be doable… Right?

I you are looking for a successful recipe how to get Ephesoft running on Linux… Beware. This blog will get you half way there (at point of initial writing). I got stuck when Ephesoft calls for Tesseract to do the actual OCR. Once I get this fixed, I will continue. However, since this is my after-work-hours project, time prevented me for actually going all the way at this time. I do think the pointers so far could help you out. This ‘manual’ is incomplete, but might be a nice starter…

Synchronize system time with a time server on the Internet

I usually run Ubuntu servers as development servers in VMware Player. And I frequently suspend/hibernate my host OS, my laptop. To my surprise Ubuntu as a guest OS is very tolerant for these interruptions. It hardly ever fails to work. Only downside is that the system time gets confused. This makes log entries less usable, because it is hard to guess the actual time. Therefore I install an ntp service, to syncronize the system time with some time servers on the Internet.

Cloning Ubuntu VMWare images

Often I use Ubuntu running in VMWare as development systems. Actually, I have created a pre-installed Alfresco image that I unzip and rename for another project. VMware Player nicely asks if I copied or moved the image, in order to create a new MAC address, or leave it as it is. Since I want to be able to run multiple VM’s at a time, I select the ‘move’ option. So far, so good.

Ubuntu however is not that fond of being moved around this way. It breaks networking. The solution? Remove these two files, and reboot Ubuntu:
sudo rm /etc/udev/rules.d/70-persistent-net.rules
sudo rm /etc/udev/rules.d/75-persistent-net-generator.rules
