Call to undefined function filter_var() on FreeBSD

• https://www.rubenerd.au/call-to-undefined-function-filter-var/

Last week I bought a Rode Interview PRO wireless microphone. It is a beautiful piece of hardware — properly wireless, with onboard storage so I can record street interviews without worrying about signal drops. I have been waiting for sunny weather to take it out for its first real test.

On paper, Linux support should be a non-issue. Plug it in, it shows up as USB mass storage, copy your WAV files off, done. And that part works perfectly. I pulled my first recordings off, edited them, everything was fine.

Today on undeadly log: Migrating mail servers from exim to OpenSMTPD (smtpd) is fun and useful

Like (we suspect) quite a few of our readers, undeadly.org co-editor Peter Hansteen runs a mail service and settled on exim as the reasonable alternative to the classic sendmail way back when.

However, that software has had its share of security issues over the years, and during the preparations for the OpenBSD 7.9 release, the ports maintainers decided that…

With the Hansteen's agreements, I made a French translation.

(For the French readers) See:

The SMTP mail server for the 21st century and onwards is OpenSMTPD, which is developed as an integral part of OpenBSD, but available in a portable variety too. It was one of those things that I had fully intended to do years ago, but I only got around to actually doing once there was a definite deadline to get it done. The time has come, as OpenBSD 7.9 will leave the exim package behind, and exim users will need to find a replacement before upgrading. This article describes my transition to OpenBSD's own OpenSMTPD mail server.

For what it's worth, I think: don't delete it from BSD Cafe Billboard. It's good to raise awareness of the reputation.

I hadn't thought of it that way. Interesting!

FreeBSD 15.2 Will Aim For The Nice KDE Desktop Installation Experience

FreeBSD 15.0 had aimed to provide a KDE desktop install option from its text-based OS installer to make for a more compelling FreeBSD out-of-the-box desktop experience. That was then delayed to FreeBSD 15.1 but that didn't end up materializing. Now the KDE desktop install option is diverted to FreeBSD 15.2...

That’s an interesting idea, though I’m not sure if it’s relevant.

The question I’m asking myself is: why is it problematic to use the expire option, which is designed for this very purpose? because sysadmins forget to configure it, which causes the relevant tables to grow?!

I think this is more relevant:

The "feature request" wish I have is to be able to backup/restore tables
preserving the counters and timestamp for each entry.

Currently I do a "pfctl -T show" and save to file on server shutdown.
Then I do a "pfctl -T add" from filename to reload table on boot.
Obviously this resets all the timestamps to the current boot time.
I know, don't reboot.

This seems me a good idea: save with good informations when rebooting is needed, as instance a "new" rebuilded kernel

Network-oriented readers will be familiar with the concept of overload tables, commonly used with state tracking options to create adaptive rulesets for such things as punishing password-guessing botnets.

A downside to tables that would tend to fill up indefinitely is that at some point they will be quite full, and the administrator would need to either manually run pfctl expire or set up a crontab entry to weed out old entries at intervals.

In fact, as the subject line seems rather inappropriate, you can even delete it if you have the necessary permissions!

Thank for the remark!
In fact, as you’ve realised, they’re not mine, but the author’s; I’ve tweaked the first post slightly.
