Linux: File containing active DHCP leases

• On openSUSE systems this is located in /var/lib/dhcp/db/dhcpd.leases
• On CentOS the leases file is in: /var/lib/dhcpd/dhcpd.leases

As soon as I find out what goes on on other systems, I 'll make new entries as needed.

SuSE Linux Yast Repositories URLs changed

During the last week, I have have noticed a change in the URLs of various package repositories in openSUSE. The correct URLs are still available at the Additional YaST Package Repositories page in the openSUSE website.

If your update system starts complaining about unaccessible repositories,then I suggest you have a look. The good news is that if you start the Add remove update sources applet from YaST and select ignore or skip from the dialog boxes complaining about faulty URL's then the system gives you a chance to remove all non working update sources immediately.

SuSE Linux: Speeding up boot time by getting rid of zmd

Here is a cool post I found at linuxQuestions.org.. If you feel that your openSUSE 10.x Linux box is taking too much time to boot, then it might be a good idea to remove ZMD altogether.

SuSE Linux: Running SQLDeveloper 1.2 on openSUSE 10.2

I have just downloaded and installed SQL developer version 1.2 from Oracle.OTN .

Immediately noticeable improvement are the new GUI, the support for two additional RDBMS's like MySQL and SQL Server and also the improved data export capability. In my opinion, the support offered by the previous version was not working correctly since it offered on DML statements for creating the tables you might have wanted to copy or move to an other database using SQL.

I had one small problem though. It seems to me that sql developer is checking the values of the JAVA_HOME and JDK_HOME variables in order to determine the JDK to use. openSUSE defaults these to the /usr/lib/jvm/java path which contains a 1.4.2 jdk, so the workaround was to modify sqldeveloper.sh file so it looks like this :

#!/bin/bash
export JAVA_HOME=/home/thanassis/java/jdk1.5.0_12
export JDK_HOME=/home/thanassis/java/jdk1.5.0_12

cd "`dirname $0`"/sqldeveloper/bin && bash sqldeveloper $*

Nvidia Howto for SuSE Linux

Tried upgrading my home Linux KDE today. Not much of of update that was but since the wind of change was already blowing into my system, I thought of updating my NVidia driver as well.

Well it worked... YaST said there was a newer version, I selected it, installed it and failed. There was no way to start X again with Sax2 complaining about amissing screen configuration. Then I did two things.

• Started YaST in text mode and removed all nvidia software
• Started X again without 3D support
• Had a good look at The SuSE linux users Nvidia howto"

For everyone else into the same kind of trouble my suggestion is Think before you click and the all time classic.RTFM.

Update source for Mozilla Products on openSUSE

I have always wondered why there were no updates for the SuSE provided Firefox. Looking a bit more carefully at the openSUSE site, I realized that in order to get updates for Firefox, SeaMonkey and Thunderbird, you need to add an additional YaST source.

The base directory for all Mozilla related products on SuSE Linux is http://software.opensuse.org/download/mozilla/.

You can add the correct path for your Linux distribution from there.

For example the openSUSE 10.2 the source URL is http://software.opensuse.org/download/mozilla/openSUSE_10.2/.

As far as I am concerned, there are more good news as I realised that the base address also offers versions for SLES9 and SLES10.
