Running an SL-C3200 Zaurus with a stock ROM.
The software: apache2-php5-mysqlclient_2.0.52_arm.ipk, mysql_3.23.49-8.7_arm.ipk.
I installed MySQL Query Browser in chrooted Debian.
The way to run it is in X/Qt by running Crd mysql-query-browser and then connecting to 127.0.0.1 not localhost.
If you first chroot and then try run it from within the chrooted environment it is not able to connect to MySQL.
