Script updates for DLink DDNS

This describes how to setup a Linux box to automatically update the DLink Dynamic DNS facility.

Designing a breakout board for the TCM8240

2013.05.23: Warning: This is an Alpha revision design. I am currently waiting for the PCBs and will update this post with (electrical) test results when the boards arrive.

To help me with the overall design of a custom PCB for my HSIS project I designed a TCM8240 breakout board.

Updating OpenWRT on a TP-LINK TL-WR703N

I was writing another page on installing OpenWRT and realized that the version I was using was no longer current. To make that page more relevant I thought I should document the steps to update the OpenWRT installation on a TP-LINK TL-WR703N.

29C3 - My first CCC

Greetings from Hamburg!

I have wanted to go to CCC for years, and this year I got my chance!

Nexus7, Android 4.2 and OpenVPN 2

I needed a way to get "road-warrior" remote access to my network resources and SSH wasn't doing everything I needed, it was time to setup a VPN. It's a common problem and there is a common solution. During my VPN configuration I was all over the Internet pulling in parts of the solution so I thought I'd wrap it all up in one place. This is a solution for my problem, yours may be different.

Commenting is enabled

I bit the bullet, wiped the userbase, installed a spam filter and enabled commenting.

If this doesn't cause me a crazy amount of extra work I'll leave it enabled, otherwise I'll shut it down.

You'll need an account to comment. Accounts need to be approved individually so there may be a delay between your request and my approve/deny decision.

Configuring a Xyplex 1640 as a terminal server

I have a bunch of networking equipment in my home lab and after a few years I got tired of getting up to move a console cable from one device to the next.

Tweaking OEL 6.3

I setup a VM host with several VMs as a test bed. The VM host is running Slackware 14 RC4, I'll upgrade to 14GA when the DVD arrives. I'm using VMWare Player to create/manage the VMs. The VMWare Guest is configured with Bridged networking giving the guest it's own IP address and allowing other hosts to connect to it. Most of the guest VMs are Oracle Enterprise Linux 6.3 (OEL 6.3) because much of the software I'm testing is from Oracle (Database, Weblogic).

Sending X-Window displays through a VPN to a VMWare Linux Client

This took me a few hours to figure out ... hopefully this will save you those hours.

I work remotely and recently had to connect to a Linux server in head-office via a VPN. My VPN client machine is 32bit windows7 ... with no X-Windows software installed.

Updated: First project with GEDA & PCB

I received the boards (10) from SeeedStudio. I built up two of them and wrote a simple fader routine to drive all 32 channels and it works! I'm actually a bit surprised because this was my first foray into circuit design, though an admittedly simple project.

I'll post the schematics, pcb-layout and gerber files in the next week or so.
