Mail Relaying in Sendmail

Date August 15, 2007

I’ve always been in favor of removing the standard Sendmail install on most Linux boxes, in favor of Postfix. I’ve found it easier to use, and easier to configure. Having a simple configuration file that doesn’t need compiling is always helpful too. However, in some cases, you really don’t like to touch [...]

Bash magic to save you time…

Date May 20, 2007

How do you turn a 12 (or more) hour job into 40 minutes? Script it…

The “gotchas” of upgrades

Date March 6, 2007

On Sunday I wrote up a “brief” little record of my upgrade nightmare. Today, I got an email from Bill reporting his anti-spam comment plugin was broken. So I decided to check in on it. I had assumed there was an issue with the PHP build I had created after the installs. [...]

Cursing Upgrades…

Date March 2, 2007

I’ve been pretty good at keeping my server up to date. I’ve taken a general policy of “if it isn’t broke, don’t touch it”. It works well, for the most part. When it comes to servers though, security is a good idea, and that plays havoc with the previous mantra.

Work, without Windows

Date November 16, 2006

It’s always been one of those items on my list to try, operating entirely at work without Microsoft Windows (r) on my laptop. Yesterday I think that possibility became all the more viable. With the move of our production servers to our corporate office, and there being no direct link to the servers, [...]

Nagios ping error

Date November 7, 2006

Stumbled on an odd one today. I was adding some new hosts to our Nagios server, and while I was looking at the interface, one of the servers kept popping up an error, the error was:

PING WARNING - System call sent warnings to stderr System call sent warnings to stderr

So I checked the [...]

Losing time

Date November 1, 2006

I have been known to lose track of time every once in a while, but not 3 days. I just logged onto our monitoring server after noticing some oddness in time. When logging on, the server said it was the 29th of October. That was 3 days ago. So I execute [...]

Nikon on Linux

Date September 18, 2006

I have been curious about building “the ultimate Linux Desktop” for a while, but one of the requirements would be support for my Nikon D70s. As I shoot in RAW format, and that is usually propitiatory per camera manufacturer (Nikon is NEF), some special software is required, so I googled for “Linux Nikon RAW”, [...]

Login history

Date September 13, 2006

This is more of a reference for myself because I keep forgetting it. The command last is used to pull up the login history for the active account. This is a handy little command to see if your account has been a little more active than it should have been (though any good [...]

Forwarded DNS Queries

Date August 31, 2006

Last night I stumbled across a little issue I hadn’t noticed before. We’re in the process of deploying a new connection to our office for improved bandwidth, and reliability. Currently I have moved half of our servers to using the new line, and a handful are still using the old line. Last [...]
