Jason's Various Ramblings

Introduction In a previous entry I discussed the differences in streaming game play to YouTube vs Twitch, as well as the differences between using hardware versus software h.264 encoding. The conclusion that I came to was that I was going to continue streaming to my YouTube channel until I decide to buy and assemble another PC specifically for Twitch…
Nope, it’s not what you think. Nothing was stolen from my house, thankfully. Rather: it was stolen before it got to my house. First a little back-story… My gaming/editing rig’s operating system drive (C: in Windows-speak) is a Samsung SM951 M.2 AHCI drive. It’s 500GB in size and is quite quick in comparison to most SATA SSDs and HDDs. But…

I’m Back(?) It’s been almost a year since my last entry which would imply that this blog isn’t that important to me. I’d say more accurately, it’s less important to me than other things in my life. Those would be things like my job, raising my dogs, taking care of my house, enjoying my new Corvette, etc. It’s not…

Assuming you’ve followed my spam-fighting adventures, you’ll know that I have a fairly successful installation of Neal Horman’s spamilter running in a FreeBSD jail, and his ipfwmtad daemon running on the jail’s host. Meaning the ipfw rules being added by ipfwmtad are done on a server different from where spamilter is running. Along with all of that, you’ll recall…

In my Putting Jails to Work entry, I detailed how I set up the jails on joker. Part of that entry dealt with the null filesystem mounts that I had to do on joker so that the jails would have access to an NFS-mounted filesystem. It turns out that I did a lot more work than was necessary, because the…

In my VXLAN: Providing Ponies for Bad System Designers entry, I discussed using an L2 overlay technology such as VXLAN to provide virtually spanned L2 VLANs over an L3 infrastructure. In this document, I’ll show via diagrams and config snippets how to build a poorly-designed network and why it’s a problem. Then I’ll use VXLAN to build a similar…

This post will show up in both the FreeBSD section as well as the Network one. It’s sort of a combination of the two. I’ve been detailing my server conversions from Linux to FreeBSD on this blog, but I held off on the final device, and that’s the router. It turned out to be a hell of a challenge…

If you’ve been following my two sub-threads on this blog regarding FreeBSD jails and fighting spam, you know the status: I have a FreeBSD server called joker that has multiple jails on it. One jail is riddler, and it handles all outbound SMTP connections. But not inbound. Further, you know that I have a reasonably complex anti-spam system set…

In my Killing Spam(mers) entry, I discussed getting both SpamAssassin and Neal Horman’s spamilter installed and working on joker. Doing so made a significant impact on the amount of spam I was seeing. However, they were working independently of one another, and what I really wanted was some sort of feedback loop. Should a message get through spamilter and be…

In the last entry, I explained how I decided to remove the Linux hypervisor from my network and replace it with a beefy FreeBSD server named joker. Instead of all of the VMs running on the former KVM server, I instead created a collection of FreeBSD jails. This post will serve to document what I did to get them…
