More postfix spam blocking and Whitelisting….

Monday, January 22nd, 2007

I almost forgot to pass along a link to a more comprehensive detailing of postfix’s anti-uce controls…. here. Also, in the last article I briefly mentioned whitelisting. IF you intend to have several blacklists active it will pay to learn how to whitelist before you HAVE to. To do so, I simply created a text [...]

More postfix spam blocking….

Monday, January 22nd, 2007

Postfix has a NUMBER of tools for rejecting unwanted messages before they get in the door and waste your CPU time on deciding “hey this mail is spam”. Up until recently I’ve mostly used the relays.ordb.org check (which in the last couple months has now gone defunct.) When we started noticing problems with ordb.org’s responsiveness [...]

Post storm

Monday, January 22nd, 2007

It almost seems like I’m back to the 6-10+ posts I day I used to do around here… I should mention that I’m just clearing out a few things that I wanted to get posted and clean out the bazillion tabs in my browsing session that I’ve been loading the last month or so. I [...]

Internet Explorer 7 on linux

Monday, January 22nd, 2007

Haven’t had the chance to try this one firsthand yet, although I’ve been watching for this. You may be familiar with ies4linux which is a script that uses wine to download/install multiple versions of Internet Explorer on a linux install. (But why oh why would you do this?) For many that do web design it’s [...]

Software raid fun…. device detection order

Monday, January 22nd, 2007

Anyone that’s setup software raid on a system with multiple storage adapters has probably run into this kind of issue, but I thought I’d mention it. Last weekend I built a machine to replace my server (the server was to be captured into a VM). The main system was going to be installed onto dual [...]

Boot up freeze/sluggishness with ubuntu 6.06.1 install cd (on 64bit AMD hardware)

Sunday, January 21st, 2007

I thought I had written about this once before, but when I searched the site to find the solution I had come across before, I couldn’t find my post…. so, sorry if this is a duplication, but I’ve run into this on some AMD 64-bit based system boards. The most recent was based on the [...]

Virtualbox virtualization open source availability

Sunday, January 21st, 2007

This last week virtualbox announced that they have released a version of their virtualization software as open source. There is a pay version as well with more features. (*read on for features available in the full version.) While I appreciate them making the core virtualization open source and currently they are likely the most advanced [...]

iScsi and AoE with linux

Sunday, January 21st, 2007

A few days ago I had reason to investigate iscsi and AoE (ata over ethernet). Both are protocols for sharing a physical drive over the network at the block level. Let me put it in context first. Traditional network file shares have been done like this…. Computer A has a large drive, it’s formatted and [...]

Windows lost administrator password rundown….

Friday, January 19th, 2007

I’ve done one or two mentions in the past of ways to recover/reset lost windows passwords and thought it was probably time for another “brain dump/web research dump” of things that I’ve run across. This is not just for lost administrator passwords, but could apply to a lost user account password as well. (I’ve found [...]

Mac/Linux/Windows usb wireless adapter D-link DWL-G122

Monday, January 8th, 2007

One of the tools I looked at having for my expanding kit has been a usb wireless adapter that would work with minimal install on Windows/Mac or Linux. As you can imagine…. it’s not as straightforward as just getting one that’s compatible with Windows…. well, after much searching I found the D-Link DWL-G122 802.11g Wireless [...]
