Trouble with vnet and pf

In the past, I have tried vnet jails with pf, and hit trouble. I was never able to get pf to allow the vnet traffic when having a default ‘block log all’ rule. More recently, I encountered the same problem when using byhve. This time, I moved byhve to another host, which is not using pf and I am writing this post to document the issue. This post is based on two gists […]

Tips for running an online conference

NOTE: This post was composed in June 2020. I think I got started running conferences in 2002 when I helped with Open Source Weekend 2003. The next year, I started BSDCan. Three years later, PGCon start. All up, I think I’ve run at least 32 conferences, two of which have been online: BSDCan 2020 and PGCon 2020. This article was planned before the conferences were held. There have been requests to share what

Accessing a Dell iDRAC 7 via Nginx reverse proxy

HEADS UP: this is still under review. Until this notice is removed, I recommend not using this. I have a Dell R720 at an ISP. The iDRAC connection is filtered, by the ISP, and is accessible only from a small number of IP addresses. Sure, this talks about a web proxy. It works.

Fixing vulns in poudriere jails

This post was originally a few tweets. It’s not really about upgrading vulnerabilities in poudriere jails either. Read this as if each paragraph was a tweet. When a FreeBSD security alert comes out, or a package is marked as vulnerable, I try to get that fixed as soon as I can. Even if not using the feature. Sometimes a vuln can be leverages against something you are using. Patch it. When it comes

cron is running all jobs twice – solved

This started earlier today and I solved it only just now. It took me a while to find out it was duplicate cron jobs, and even longer to find out why. It started with lockf notifications (if you’ve never heard of lockf before, please read this Twitter thread for examples). In short, one of those emails said: lockf: /var/run/periodic.hourly.lock: already locked I looked to see if there were any long-running jobs which might
