For years I’ve run the dev, test, and stage nodes for FreshPorts off servers in my basement. This meant that those hostnames have always pointed at my home IP address. I’d like to change that. I first started this using interactive commands (e.g. wg set) but found that approach unsatisfactory. I think directly editing the …

NOTE: I wrote this, got stuck, then went a slightly different direction: I stopped using wg set Instead, I updated the configuration files directly I was not satisfied with the wg approach Although it is great for modifying things on the file, I don’t think it helps novices learn Wireguard I’m leaving it here anyway. …

In this post I will be creating a ‘new’ jail which uses vnet. I say ‘new’ because I am actually Converting an iocage jail to a vanilla jail which happens to use vnet. NOTE: I originally failed to get this to work. You can read about it. I’m going to repost this article soon with …
In this post I will be creating a ‘new’ jail which uses vnet. I say ‘new’ because I am actually Converting an iocage jail to a vanilla jail which happens to use vnet. NOTE: I failed to get this to work. I’m still going to post it though. What I did wrong: I should not …
The R720 is showing a message like this from time to time: Jan 1 07:42:20 r720-01 kernel: sonewconn: pcb 0xfffff835e785d5b8: Listen queue overflow: 8 already in queue awaiting acceptance (1 occurrences) Jan 1 08:02:21 r720-01 syslogd: last message repeated 1 times Jan 1 08:27:22 r720-01 kernel: sonewconn: pcb 0xfffff835e785d5b8: Listen queue overflow: 8 already in …
I am adding IPv6 addresses to each of my servers. This post assumes the server is up and running FreeBSD 11.1 and you already have an IPv6 address block. This does not cover the creation of an IPv6 tunnel, such as that provided by HE.net. This assumes native IPv6. In this post, I am using …
I started seeing this recently. It appears in the logs on my firewall: It does not seem to be disturbing anything, other than my nerves. The classical situation is: two PCs are arguing over the same IP address. Each NIC has a unique MAC address, used at the physical network segment. We often refer to …

Tonight I asked a question in the OpenVPN IRC channel on FreeNode. me: I’m getting ready to set up a new server, running an OpenVPN client. It will be running several virtual machines (FreeBSD Jails). Each VM will have both a public IP address and a non-routable IP address. I’m hoping to access all those …
I had a Bacula job fail today: Is bacula-sd running on crey? Yes it is. Can I telnet to port 9103 on crey? Yes, I can: $ telnet 10.5.0.20 9103 Trying 10.5.0.20… Connected to crey.example.org. Escape character is ‘^]’. What about from the nyi-fd server? Can I telnet from there? $ telnet 10.5.0.20 9103 Trying …
The other day, I disconnected the ethernet cable from my gateway to reroute the cable. Then, perhaps coincidentally, I started seeing these entries: Jul 2 15:19:57 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt len 4294967294) Jul 2 15:28:01 bast kernel: fxp0: discard frame w/o leading ethernet header (len 4294967294 pkt …
