Playing With LDAP

Currently it's a pain in the rear to manage users and mail accounts on my network. Poor planning on my part, but really it has more to do with being unfamiliar with eGroupware when I implemented it. I actually had to write myself a set of instructions to follow each time I add a user to the network, which is quite embarassing actually.

I have a Windows 2003 server that authenticates Windows clients through Active Directory.
The majority of our file shares occur between a Windows PC and a Linux server, so I've implemented NFS and installed the NFS tools for Windows on each of the Windows clients.My Linux clients have been authenticating over NIS. eGroupWare pulls authentication for users from NIS as well, but it doesn't have the ability to add new accounts or change passwords. I'm using Cyrus for mail, so that requires another step where the user mailbox has to be created.

So, I got a wild hair today, since I had all these virtual machines lying around, and created a virtual LDAP server for testing. I was able to migrate my network user and group lists into it very easily, but I haven't found a way for it to import all the password information from my NIS server's shadow file.


Read The Docs, Save Some Time

Yeah, so I decided to install the 64 bit Ubuntu 7.10 server into a VirtualBox virtual machine.

Turns out, VB still doesn't support 64 bit guest OS's.

So, I downloaded the 32 bit Ubuntu 7.10 server. After three times of giving up when the install was installing the kernel because it froze, so I downloaded the 'Alternate Install CD'. That didn't work any better.


My First Dedicated Virtual Server

I love VirtualBox. Really.

I just set up a dual CPU AMD64 Opteron 270 (each processor is dual core, so I effectively have four 2 GHz CPU's) with 4 GB of RAM (and another 4 on the way) running Ubuntu 7.10 64 bit server edition.

The motherboard on this server has dual gigabit ethernet ports, and I bound them together into one network port that nearly gives me 2 Gb of bandwidth. I then bridged this network port and configured several TAP devices that I can designate to the guest machines.


Stupid Error Dialog

Here's a Microsoft error I'd never seen before:

Um, do I hit Move or Copy... oh wait, you can't!


Posting On The Road

Well here I sit in the hospital while they try to stop my wife's contractions. They have wireless here, so I was able to download photo editing software (mirage) for my nokia to resize a photo of my wife that I took with the Nokia and upload it to her blog.

I figured we've been married almost 17 years, so maybe she won't
divorce me over one photo.

It's cool that you can do all that on the road.


Microsoft Wants To Give Away Your Health Records

Microsoft has starting pushing 'HealthVault' - their version of online medical records. Be afraid. Be very afraid!

Read on for an in-depth diagnosis:Microsoft infers that this is a solution to storing medical records digitally:


Ugh. High-definition recording a bust so far

I picked up the pcHDTV card HD-5500 (specifically designed for Linux) and installed it tonight.

My goal was to use my MythTV box to record the basic digital and basic HD content.

I've never been so pissed in my life.

I just got home with my brand spankin' new copy of Half-Life 2. It's supposed to be an amazing single player game.

Previously I'd sworn off of Valve due to their attitude towards Linux users, but I figured I'd give 'em one more shot.

Unfortunately, this is what I got:<%image(oss/20070920-steamsux.jpg|432|438|)%>


HD For The Masses

I've been considering a switch to DirecTV. Suddenlink, my local cable provider doesn't offer ANY of the major four networks in high definition. Initially when I signed up, I was told that I would get NBC, CBS, ABC and FOX all in HD.Low and behold, it ain't so. In fact, without paying extra for HBO or CINIMAX, I only get something like 7 HD channels, and one is in Spanish.

So, I checked with DirecTV who claims to have over 100 HD stations by the end of the year.

Wow, I can get 9 HD channels from DirecTV, and get this - none include ABC, NBC, CBS or FOX. Thanks.

Idea two: try to get MythTV to record digital cable / HD. In researching capture cards for MythTV I stumbled across this little gem from PcHDTV.

And, it's cheaper than what I paid for my analog Hauppauge capture card. I might just have to try that out!


Drawing On The Internet Tablet Screen

There are some things that you just have to do differently when you're programming for a small device like the Nokia n800. The processor is just not as powerful as your desktop.

One of those things is how you draw graphics.I've been working on the Python GTK Kinetic scrolling widget to get it's speed enhanced and finally made a breakthrough.
