We sit down to chat with Justin Sherrill of the DragonflyBSD project about their new 3.6 release. Later on, we\’ll be showing you a huge tutorial that\’s been baking for over a month – how to build an OpenBSD router that\’ll destroy any consumer router on the market! There\’s lots of news to get caught up on as well, so sit back and enjoy some BSD Now – the place to B.. SD.

Headlines

OpenSSH 6.4 released

Security fixes in OpenSSH don\’t happen very often
6.4 fixes a memory corruption problem, no new features
If exploited, this vulnerability might permit code execution with the privileges of the authenticated user and may therefore allow bypassing restricted shell/command configurations.
Disabling AES-GCM in the server configuration is a workaround
Only affects 6.2 and 6.3 if compiled against a newer OpenSSL (so FreeBSD 9\’s base OpenSSL is unaffected, for example)
Full details here

Getting to know your portmgr-lurkers

Next entry in portmgr interview series
This time they chat with Mathieu Arnold, one of the portmgr-lurkers we mentioned previously
Lots of questions ranging from why he uses BSD to what he had for breakfast
Another one was since released, with Antoine Brodin aka antoine@

FUSE in OpenBSD

As we glossed over last week, FUSE was recently added to OpenBSD
Now the guys from the OpenBSD Journal have tracked down more information
This version is released under an ISC license
Should be in OpenBSD 5.5, released a little less than 6 months from now
Will finally enable things like SSHFS to work in OpenBSD

Automated submission of kernel panic reports

New tool from Colin Percival
Saves information about kernel panics and emails it to FreeBSD
Lets you review before sending so you can edit out any private info
Automatically encrypted before being sent
FreeBSD never kernel panics so this won\’t get much use

Interview – Justin Sherrill – justin@shiningsilence.com / @dragonflybsd

DragonflyBSD 3.6 and the Dragonfly Digest

Tutorial

Building an OpenBSD Router

Replace your crappy consumer router with a custom-built one
Uses the pf firewall and other built-in OpenBSD utilities
Very secure, built entirely on top of open source software
Puts YOU in control of your network

News Roundup

BSD router project 1.5 released

Nice timing for our router tutorial; TBRP is a FreeBSD distribution for installing on a router
It\’s an alternative to pfSense, but not nearly as well known or popular
New version is based on 9.2-RELEASE, includes lots of general updates and bugfixes
Fits on a 256MB Compact Flash/USB drive

Curve25519 now default key exchange

We mentioned in an earlier episode about a patch for curve25519
Now it\’s become the default for key exchange
Will probably make its way into OpenSSH 6.5, would\’ve been in 6.4 if we didn\’t have that security vulnerability
It\’s interesting to see all these big changes in cryptography in OpenBSD lately

FreeBSD kernel selection in boot menu

Adds a kernel selection menu to the beastie menu
List of kernels is taken from \’kernels\’ in loader.conf as a space or comma separated list of names to display (up to 9)
From our good buddy Devin Teske

PCBSD weekly digest

PCDM has officially replaced GDM as the default login manager
New ISO build scripts (we got a sneak preview last week)
Lots of bug fixes
Second set of 10-STABLE ISOs available with new artwork and much more

Theo de Raadt speaking at MUUG

Theo will be speaking at Manitoba UNIX User Group in Winnipeg
On Friday, Nov 15, 2013 at 5:30PM (see show notes for the address)
If you\’re watching the show live you have time to make plans, if you\’re watching the downloaded version it might be happening right now!
No agenda, but expect some OpenBSD discussion
We\’ll let you know if there is a recorded version.

The very extensive written version of today\’s tutorial, with lots of extras we didn\’t mention, is posted on bsdnow.tv, as always – give it a read! There are sections about setting up the router to tunnel all (or specific parts of) your traffic through a VPN or Tor, how to make the router automatically check for updates and email them to you, and much more.
Send questions, comments, show ideas/topics, etc to feedback@bsdnow.tv
We don’t check YouTube comments, JB comments, Reddit, etc. If you want us to see it, send it via email (the preferred way) or Twitter (also acceptable)
