Adobe Coldfusion MX on Ubuntu Server

May 10th, 2008 @ 12:15 by Willem

Ever since I went ‘Apple’, the urge of moving away from Microsoft Windows operating systems is getting bigger and bigger. A couple of weeks ago I installed a two Ubuntu servers (v7.x) at work. Mainly for testing , and educational purposes.
The installation went extremely smooth on old Compaq ML370 server hardware. So, as a test I tried to install Adobe Coldfusion MX (Coldfusion 8 ) on the Ubuntu server (with Apache, and MySQL).

There are several postings on the Internet suggesting that it should be possible. Even though Ubuntu isn’t on the supported platforms list for Adobe Coldfusion MX.

Ubuntu ‘Hardy Heron’ Released

April 25th, 2008 @ 16:23 by Willem

As of yesterday, the latest Ubuntu release ‘Hardy Heron‘ is available for download (both client and server). Every time a major Linux distri(bution) hits ‘the shelves’, the Linux community roars. With each release (Ubuntu or whatever flavor) the Linux community gets closer, and closer to Windows.

Even though the OS itself is getting better and better. It still lacks the support of decent major software like Adobe Creative Suite, etc. It’s missing the software people use in every day (business)life.
Sure, there a million different ways of running Microsoft Office or Adobe Photoshop on a Linux OS, but these require a commercial piece of software (CrossOver) , or in depth knowledge of the OS to make it work (Wine in some cases). Two things that shouldn’t be required. Not if you’re used to Windows (or Apple’s OSX). And even if you find a ’substitute’ it’s most likely to have an awful user experience.

The average housewife won’t use Linux, because her friends all use Windows. All those nice little Windows programs, which makes life easier (or a living hell with all the mal/spyware out there). So if the Linux community wants to make a difference they need to create some sort of critical mass (by their selves, or by Microsoft screwing up) to get the attention of the ‘normal’ user. But in a community where there’s no real (commercial) business model, it’s gonna be damn hard.

Microsoft created this critical mass by playing (probably) the best marketing trick in the world; Release Windows 95, and turn a blind eye to those who use a pirated copy at home. The home users create demand on the workfloor, so businesses start to use it on their workstations. Soon everyone was addicted. And now it’s damn hard to beat the addiction.

B.t.w., Apple is doing it a lot better. They created a nice and stable OS (just like the average Linux desktop distribution), BUT the OS has ALL the relevant drivers for the hardware used. ALSO they have a complete (and cheap) software suite (iLife and iWork), which is more than enough for the average family. No need to search the caverns of the Internet for software, and they look and feel the same as the OS.

So, I guess that my conclusion is that the OS is nearing perfection, but it (Linux in general) lacks good and decent third party software (and a good marketing machine :) )

In the mean time; I’m gonna upgrade my Linux (mail, web, and ssh) servers at work to ‘Hardy Heron’.

VMWare and Firewall / VPN Clients

April 8th, 2008 @ 14:33 by Willem

Well, that was another morning well spent….

A couple off weeks ago I started experimenting with FreeRADIUS on Ubuntu server (v6.06.2 TLS). Mainly because I needed to test some things for work. So I used VMWare to experiment. The networking part was set-up as Bridged.

Today, I wanted to test with iperf (a tool for network performance testing). So I launched the virtual machine, but there was no network connectivity. ifconfig showed that eth1 didn’t received an IP adres.
So I ran every possible test there was;

  • restarted the interfaces (/etc/init.d/networking restart)

This resulted in the following;

Listening on LPF/eth1/00:0c:29:68:e3:eb
Sending on LPF/eth1/00:0c:29:68:e3:eb
Sending on Socket/fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 12

The “DHCPDISCOVER” messages continue about 4 times, then the message:

No DHCPOFFERS received.
No working leases in persistent database - sleeping.

  • restarted the DHCP server
  • rebooted the virtual machine
  • changes the networking to NAT instead of Bridged (this way, connectivity was restored, but not the way I wanted. I needed Bridge-mode)
  • Tried to run the virtual machine on OSX (VMWare Fusion), which worked surprisingly.

After this I ran Wireshark on my server to see if DHCP request were coming in…. And you might have guessed; No DHCP request were reaching the DHCP server. So the problem was work PC related…. As a matter of fact, I had the Cisco VPN client running….. Which didn’t allow the DHCP request broadcast.

Shutting the VPN client down solved the DHCP problem. After the virtual machine worked I could reinitiate the VPN.

Mental note to myself: do NOT boot/restart the virtual machines when the VPN is up.
