Open Source Firewall
At work we use commercial Firewall appliances, where the vendors charge a fortune for the updates and support, its poor value for money, so I’m going to be looking into the Open Source alternatives, here’s the ones I’ve identified so far, hopefully I’ll get chance to review them and post my findings -

VMWare Server sucks!
At the office we use VMWare Server on a couple of different systems to run “appliance” based applications, the problem is every few months the Web interface suddenly screws up and all we get is 503 errors when attempting to login. I’ve searched high and low for the cause and solution to fix it, as far I can tell its occurs because the server randomly deletes or corrupts some important Tomcat related content. Then the only solution I’ve found to fixing this is completely uninstall VMWare Server, remove all the licenses, reboot the system and then re-install VMWare server.
The last time this occurred, after re-installation, VMWare refused to accept my license key, even when I tried re-entering it I got errors stating its invalid, I fixed this by going into the registry and overwriting the Registry as follows -
To change the serial number:
Go to Run
Type in regedit
Go to HKEY_LOCAL_MACHINE – Software – VMware, Inc.
Expand VMware, Inc.
Expand the subfolder named VMware Server
Go to License
Right click on Serial on the right window pane
Select modify and paste the new serial number/license key
Hit OK
Projx Transfer
Some users are reporting problems with Projx Transfer and the new version of Eclipse, this is something I need to investigate, but won’t have time to do it until next week, please continue using Eclipse 3.4 – 3.5 until then..
Server Outage
Sorry the website had been down for a little while, there was an IP routing problem which I did not spot. I’m currently working on a High Availability LAMP setup, which I’ll post details and results for a little later, there should be some interesting trinkets in there for people looking for File replication, Database replication etc on a Linux based servers.
Understanding and managing IT workers
Anybody who works in IT or wants an insight into how IT Workers think, then I highly recommend the following article written by Jeff Ello:
