suppressing motd on FreeBSD 13.0+

Leave a Comment / motd / By /

On one recent FreeBSD 13 host, I noticed a lack of motd. The MOTD (Message Of The Day) appears when you login. Typically, it looks like this: [dan@rose:~] $ r720 Last login: Mon Aug 2 00:30:13 2021 from air01.startpoint.vpn.unixathome.org FreeBSD 13.0-RELEASE-p3 (GENERIC) #0: Tue Jun 29 19:46:20 UTC 2021 Welcome to FreeBSD!

Trouble with vnet and pf

Leave a Comment / pf, vnet / By /

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

Leave a Comment / BSDCan, Conferences, Conventions, PGCon / By /

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

Leave a Comment / DELL, nginx, R720 / By /

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. So does the ssh forwarding shown at the bottom of this post. NOTE: I should start monitoring that IP addr

Ignore files in a subversion working copy

Leave a Comment / subversion / By /

To ignore files in your subversion working directory, try this. [dan@dev-ingress01:~/scripts]: $ svn st M . ? helper_scripts ? show-config.sh ? test-categories.pl ? test-new-xml-code-single.sh ? test-new-xml-code-starting-from.sh I want to ignore all those files, so: $ svn st > .IgnoreThese Then I edit the file, so only the file names are shown. Something like this: Then tell subversion to ignore that list of files. $ svn propset svn:ignore -F .ignoreThese . property ‘svn:ignore’ set

Fixing vulns in poudriere jails

Leave a Comment / poudriere / By /

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

Leave a Comment / General / By /

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

OpenVPN: unsupported certificate purpose

Leave a Comment / General, OpenSSL, OpenVPN, ssl-admin / By /

See also SSL client vs server certificates and bacula-fd. I use OpenVPN since at least 2008 – now going on 13 years. I find it to be reliable and stable. A few days ago, I added another client to a VPN. I run this particular network with self-signed certificates which I create using ssl-admin – I find it particularly useful for this purpose. The problem Away I went, creating a new certicate, bundled

Are all installed packages available for reinstall?

Leave a Comment / FreeBSD, Nagios, pkg / By /

When you install a package, you want to know it’s still around to reinstall. You’ve probably never given this much thought. Neither had I, until I read this post on Reddit. In my case, I run my own poudriere server which allows me to run my own package server. Why run your own package server? build ports with non-default configuration settings: Want databases/mantis build for PostgreSQL, not MySQL? (and who wouldn’t?) – You
