FreeBSD Remote Process Plugin: Final Milestone Achieved

> Moritz Systems have been contracted by the FreeBSD Foundation to modernize the LLDB debugger’s support for FreeBSD. We are working on a new plugin utilizing the more modern client-server layout that is already used by Darwin, Linux, NetBSD and (unofficially) OpenBSD. The new plugin is going to gradually replace the legacy one.

Tailscale on OpenBSD

> I spent some time setting this up today evening and thought I’d post the steps here. Nothing fancy, just putting together various pieces actually.
> I assume you know what Tailscale is; if not check out their website. Basically it is a mesh network built on top of Wireguard. Using it you can have all your devices both within your LAN(s) and outside be on one overlay network as if they are all on the same LAN and can talk to each other. It’s my new favourite thing!

macOS to FreeBSD migration a.k.a why I left macOS

> This is not a technical documentation for how I migrated from macOS to FreeBSD. This is a high-level for why I migrated from macOS to FreeBSD.
> Not so long ago, I was using macOS as my daily driver. The main reason why I got a macbook was the underlying BSD Unix and the nice graphics it provides. Also, I have an iPhone. But they were also the same reasons for why I left macOS.

Our monitoring of our OpenBSD machines, such as it is (as of November 2020

> We have a number of OpenBSD firewalls in service (along with some other OpenBSD servers for things like VPN endpoints), and I was recently asked how we monitor PF and overall network traffic on them. I had to disappoint the person who asked with my answer, because right now we mostly don't (although this is starting to change).

OPNsense 20.7.6 released

> This update brings the usual mix of reliability fixes, plugin and third party software updates: FreeBSD, HardenedBSD, PHP, OpenSSH, StrongSwan, Suricata and Syslog-ng amongst others.
> Please note that Let's Encrypt users need to reissue their certificates manually after upgrading to this version to fix the embedded certificate chain issue with the current signing CA switch going on.

FreeBSD 11 goals and discussion

• Something that actually happened at BSDCan this year...
• During the FreeBSD devsummit, there was some discussion about what changes will be made in 11.0-RELEASE
• Some of MWL's notes include: the test suite will be merged to 10-STABLE, more work on the MIPS platforms, LLDB getting more attention, UEFI boot and install support
• A large list of possibilities was also included and open for discussion, including AES-GCM in IPSEC, ASLR, OpenMP, ICC, in-place kernel upgrades, Capsicum improvements, TCP performance improvements and A LOT more
• There's also some notes from the devsummit virtualization session, mostly talking about bhyve
• Lastly, he also provides some notes about ports and packages and where they're going ***

An SSH honeypot with OpenBSD and Kippo

• Everyone loves messing with script kiddies, right?
• This blog post introduces Kippo, an SSH honeypot tool, and how to use it in combination with OpenBSD
• It includes a step by step (or rather, command by command) guide and some tips for running a honeypot securely
• You can use this to get new 0day exploits or find weaknesses in your systems
• OpenBSD makes a great companion for security testing tools like this with all its exploit mitigation techniques that protect all running applications ***

NetBSD foundation financial report

• The NetBSD foundation has posted their 2013 financial report
• It's a very "no nonsense" page, pretty much only the hard numbers
• In 2013, they got $26,000 of income in donations
• The rest of the page shows all the details, how they spent it on hardware, consulting, conference fees, legal costs and everything else
• Be sure to donate to whichever BSDs you like and use! ***

Building a fully-encrypted NAS with OpenBSD

• Usually the popular choice for a NAS system is FreeNAS, or plain FreeBSD if you know what you're doing
• This article takes a look at the OpenBSD side and explains how to build a NAS with security in mind
• The NAS will be fully encrypted, no separate /boot partition like FreeBSD and FreeNAS require - this means the kernel itself is even protected
• The obvious trade-off is the lack of ZFS support for storage, but this is an interesting idea that would fit most people's needs too
• There's also a bit of background information on NAS systems in general, some NAS-specific security tips and even some nice graphs and pictures of the hardware - fantastic write up! ***

News Roundup

FreeBSD periodic mails vs. monitoring

• If you've ever been an admin for a lot of FreeBSD boxes, you've probably noticed that you get a lot of email
• This page tells about all the different alert emails, cron emails and other reports you might end up getting, as well as how to manage them
• From bad SSH logins to Zabbix alerts, it all adds up quickly
• It highlights the periodic.conf file and FreeBSD's periodic daemon, as well as some third party monitoring tools you can use to keep track of your servers ***

Doing cool stuff with OpenBSD routing domains

• A blog post from our viewer and regular emailer, Kjell-Aleksander!
• He manages some internally-routed IP ranges at his work, but didn't want to have equipment for each separate project
• This is where OpenBSD routing domains and pf come in to save the day
• The blog post goes through the process with all the network details you could ever dream of
• He even named his networking equipment... after us ***

LibreSSL, the good and the bad

• We're all probably familiar with OpenBSD's fork of OpenSSL at this point
• However, "for those of you that don't know it, OpenSSL is at the same time the best and most popular SSL/TLS library available, and utter junk"
• This article talks about some of the cryptographic development challenges involved with maintaining such a massive project
• You need cryptographers, software engineers, software optimization specialists - there are a lot of roles that need to be filled
• It also mentions some OpenSSL alternatives and recent LibreSSL progress, as well as some downsides to the fork - the main one being their aim for backwards compatibility ***

PCBSD weekly digest

• Lots going on in PCBSD land this week, AppCafe has been redesigned
• The PBI system is being replaced with pkgng, PBIs will be automatically converted once you update
• In the more recent post, there's some further explanation of the PBI system and the reason for the transition
• It's got lots of details on the different ways to install software, so hopefully it will clear up any possible confusion ***

FreeBSD and OpenBSD in GSOC2014

• The Google Summer of Code is a way to encourage students to write code for open source projects and make some money
• Both FreeBSD and OpenBSD were accepted, and we'd love for anyone listening to check out their GSOC pages
• The FreeBSD wiki has a list of things that they'd be interested in someone helping out with
• OpenBSD's want list was also posted
• DragonflyBSD and NetBSD were sadly not accepted this year ***

Yes, you too can be an evil network overlord

• A new blog post about monitoring your network using only free tools
• OpenBSD is a great fit, and has all the stuff you need in the base system or via packages
• It talks about the pflow pseudo-interface, its capabilities and relation to NetFlow (also goes well with pf)
• There's also details about flowd and nfsen, more great tools to make network monitoring easy
• If you're listening, Peter... stop ignoring our emails and come on the show! We know you're watching! ***

BSDMag's February issue is out

• The theme is "configuring basic services on OpenBSD 5.4"
• There's also an interview with Peter Hansteen (oh hey...)
• Topics also include locking down SSH, a GIMP lesson, user/group management, and...
• Linux and Solaris articles? Why?? ***

Changes in bcrypt

• Not specific to any OS, but the OpenBSD team is updating their bcrypt implementation
• There is a bug in bcrypt when hashing long passwords - other OSes need to update theirs too! (FreeBSD already has)
• "The length is stored in an unsigned char type, which will overflow and wrap at 256. Although we consider the existence of affected hashes very rare, in order to differentiate hashes generated before and after the fix, we are introducing a new minor 'b'."
• As long as you upgrade your OpenBSD system in order (without skipping versions) you should be ok going forward
• Lots of specifics in the email, check the full thing ***
