Lately I’ve been playing around with the Spread Toolkit, and I gotta say, its cool and fun.
I got started on this because at my day job, we use spread to collect the error log from our web cluster onto the machine we regularly log into to do our dev work. This gives you a […]
Today one of GeekISP mail servers was listed in the SpamCop blacklist for hitting a spam trap. I learned quickly that for all SpamCop has done for good, it can be a huge problem as well.
For those not familiar with SpamCop, they are an anti-spam web service dating to around 1998. They offer […]
This morning starting at 4:30am ET I had to deal with a runaway mail server trying to connect over and over to the GeekISP inbound mail server. Most of my spam countermeasures are somewhat fire-and-forget, or really only require tuning based on message content, so I was a little rusty when dealing with this.

I recently became aware of an interesting fact about RAID controllers - specifically the ones that come with the option for battery backup units.
This probably comes as no shock to the reader familiar with high end RAID components, but it was to me. Anyway, it turns out that without a battery backup unit on […]
It’s been a busy few weeks, and while there’s nothing truly major to report in my usual longwinded, excruciatingly detailed fashion, there are a few more minor points:
I started my new job at WAWD on Nov. 14th. This week of working from home has been good. It’s kinda nice to be able to […]
So far, I’ve managed to do the following:
Install a HiFN card.
Remove critical system files from a machine about to enter production.
Nearly wipe out my home computer.
I just need to spill my coffee on the open Soekris on my desk, and then I’ll be set!
Update: It’s been a long day, but I’ve now got my Soekris […]
Looks like I’ll be moving GeekISP to it’s own /27, with 29 whole IPs. Oh the excitement.
Mostly as a result of the increasing number of SSH brute-force attacks (i.e. scans, etc), I’d like to have a proper firewall in front of all my servers, since not all are upgraded on the same schedule, and […]
Finally, after very much pain, stopgap measures, and testing, I have the architecture that I want for GeekISP. Some key points:
All important content is on some sort of hardware RAID disks. Home directories, web docs, and mail are the biggest examples.
All important content is available via a fast, reliable NFS server (note, a […]
