This is not my typical type of post, but as I have said, communications and networking are things that excite me greatly. It's why I collect antique telephones, why I enjoy scanner and shortwave listening, why I learned the OSI model and have spent much of my career in and …Continue reading
I recently learned about the
program map type in the Linux automounter.
You can read about it here, but there is little information about it, and I was unable to find any web pages about it, so I am writing this post since it might help others.
The NFS automounter …Continue reading
As mentioned previously, I continue to be inundated with spam email. Fortunately, every spam has an observable email format: the email comes in the form of firstname.lastname@example.org.TLD.
This allows me to update my
blocked_senders file to defer every email in that format with a 450, using

I've been busy at home, but not working in my home lab. Lately I have been preoccupied by a few things.
First, I have been busy with prepping -- I can see how things are going, and I predict we will need stores of supplies, so I have been busy building …Continue reading
Somehow I have been added to several mailing lists, all run by the same organization. The emails look legit, and are ones that I might have subscribed to, but I cannot get off of them no matter what I do -- it seems that they ignore all requests to be removed …Continue reading

I have recently switched most of my offsite network connections to WireGuard, away from ZeroTier. This is great for all of my systems except for one: the NAS (a Synology DS118) I have at a friend's house for offsite backup. That NAS can run ZeroTier and WireGuard, but I don't …Continue reading
A quick update on my OSPF cutover. With one exception, everything has worked great. The one exception is that OSPF would not work over the WireGuard link between my USG and my primary DigitalOcean VM that runs FreeBSD 12 and FRR7. I thought that was odd, since OSPF worked fine …Continue reading
I have been hard at work these last few weeks in my home lab, and have done quite a bit. Here are a few of the things I have done:
I am a system engineer in the Raleigh, NC area. My main interests are Unix, VMware, and networking. More about me, and how I got started.
