Open Source Firewall

Kelvin — Tue, 20 Jul 2010 14:05:32 +0000

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!

Kelvin — Thu, 08 Jul 2010 10:16:49 +0000

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.

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:

Windows 7 + iPhone Bluetooth

Kelvin — Fri, 21 Aug 2009 22:32:09 +0000

Well we finally received access to the Windows 7 Pro RTM, personally I’ve been running an RC for several month and think its the most polished version of Windows yet, but many people will find it difficult to adjust to.

I’ve ran into a few issue with getting its Bluetooth support working with my iPhone, it appeared with the yellow triangle exclamation icon, not sure why, but this can be fixed by right clicking the phone icon, going to properties -> services and unticking the Wireless iAP option, click ok, right-click on the phone icon and select Connect using -> Access point.

Domain name change

Kelvin — Thu, 20 Aug 2009 15:29:41 +0000

I’ve always operated my email and website from different domains, I’ve now decided time to merge them under the projx.it, this will keep my email address simple but also keep the site name relevant. If you spot any broken links, please let me know.

MySQL HA

Kelvin — Wed, 19 Aug 2009 14:59:41 +0000

We’re currently in the process of splitting our websites out onto pairs of servers for High Availability, unfortunately MySQL is pretty poor when it comes to this, its replication facilities leave a lot to be desired and often fall out of sync. But there is a collection of scripts called Maatkit which can help fix this. Here’s a good tutorial http://blogama.org/node/39

Proj-x Transfer v1.2.0 … come and get it!

Kelvin — Sun, 21 Jun 2009 22:50:18 +0000

Transfer v1.2.0 is available for download from here, please be aware that the new version requires you have the DLTK is installed.

UPDATE: Note that I developed, compiled and tested this release of Transfer with Eclipse 1.4.5 and PDT 2.1 available from here and it works! if you experience problems with Transfer and would like me to fix it, then you need to provide precise details on what your running and how I can recreate the problem, if you don’t, then your requests will be ignored.

So, please let me know if you have any problem, and don’t forget to leave precise details.

Proj-x Transfer fix

Kelvin — Wed, 10 Jun 2009 14:38:36 +0000

I’ve finally had some free time to spend on fixing Transfer, it seems the problems were not caused by bugs, instead other plug-ins such as PDT (from v2 onwards) changed the way they’re implemented and started using the Eclipse DLTK (Dynamic Language Tool Kit) which meant Transfer no longer knew how to process requests from the new PHP Explorer (This was not a problem for me, as I use an older version of PDT).

Anyway, I will release a test version of Tranfer 1.2 shortly, note its not final, I intend to add more error checking and some default settings.

Please note the new version of Transfer required the DLTK be installed, I’ll add instructions for this when I release the test.
