When a program crashes, I sometimes want to figure out why it crashed.
What do I do with the core dump?

The core(2) man page references gdb(1), but that seems like the wrong
answer because it starts with "g".

Thomas 
  Gdb is the answer for userspace applications . I am not sure what is used today for kernel dumps on openbsd.  Some bsds use(ed) a modified gdb for kernel dumps . You could, in theory , use lldb from llvm/clang but this is a wip and I am not sure how useful it would be .

Have seen similar discussion might be @talk. Some people talk about rump kernel.
I think It supports NetBSD I know for sure. Below some details. Not
Quite Sure about
validity. Hope it Helps. Below links.

Hello,
Registration for pkgsrcCon, London is now open[1]. A pre-event social

The events are open to all, there are no tickets on sale. However
registration is required for The BCS on Saturday.

Registration website closes on the 29th of June.

You are likely to hear the following talks to on Saturday and others
(waiting for replies).

In no particular order:
Giovanni Bechis - Pledge in OpenBSD
Pierre Pronchery - pkg-query
Thomas Merkel - Testing your pkgsrc development on multiple platforms
with vagrant and virtualbox
Sevan Janiyan - A mix of two halves
Bennie Siegert - Bulk builds in the cloud
Alistair Crooks - pkgsrc - foundations & abstractions, building from
source on 23 platforms
Alistair Crooks - Running a third of the internet on BSD
David Spencer - Slackbuilds
Charles Forsyth - Something regarding portability (details TBA)

If you would like to give a talk on Saturday, we still have slots open.
Let me know

Hi Sujit,

A URL by itself may or may not be important - it depends on the
application, the data involved, and the cloud provider.

Cloud security is a complex topic as the responsibliity for information
security controls is often shared between the tenant and the cloud
provider.  "Shared" can also mean misunderstood, as in "Hey, I thought
you guys were doing access control. What gives?" This is not uncommmon,
particularly for small firms who don't have a security officer, or
someone with a clue about information security.

A good start for understanding information security for these
environments is the "Cloud Security Alliance",
https://cloudsecurityalliance.org , a non-profit who has been
around for a while (2008 or so).  Their Cloud Controls Matrix (v3.0.1)
is a very useful tool for evaluating security controls.

Full disclosure - I'm not associated with CSA in any way, although I
have used their CSA Matrix along with our own custom toolkit to assess
controls at multiple cloud providers.  It's worth a look.

Best,
Jim B.

Subject: [talk] Permission is denied when I try to run certain programs
Message-ID: <1498300302.2914047.1019867120.6FF207B4@webmail.messagingengine.com>

My OpenBSD 6.1 system is in a state where I cannot run certain programs
because of a lack of permission. What could the issue be? Perhaps
related, this started happening around the same time when I started
getting kernel panic upon trying to create a softraid device for my
encrypted partition, which has always worked before. Both of these
issues started right after somebody unplugged my computer's while it was
running, but people have done that many times without these issues. It
is possible that I broke something while trying to fix something else.

This happens with python3.6, for example. Most programs seem fine
though.

Looks like your disk got corrupted... If you have user data on it,
try to save it... Forcing an fsck on it will make it better but you
might lose stuff in the process.

It was indeed wxallowed. I also happened to figure it out by running
dmesg.

Since the error that I get when trying to mount the encrypted partition
is that an "optional metadata checksum" was invalid, I think that there
is a good chance that the partition could be recovered simply but that
this strange state is not supported by the operating system.
Fortunately, I had made a backup, and now that I can run python, I have
recovered the backup.

Hello,
We should hopefully have a video stream next week from pkgsrcCon thanks
to Allan Jude & ScaleEngine, I just need to get a camera sorted out. I
was wondering what setup you're using for the streams from NYCBUG.

There was mention of the Logitech C922 Pro webcam for BSDCan, is this
the camera recommended for use??

This has mostly been Patrick M's domain... I'm sure he'll reply sooner
than later.

Good luck Sevan.

Yes. That is the cam I use. Keep it close to the speaker and you will pick up speaker and good room reaction. 
Audio board feeds are always better to get but can be hard to get set up. 
Do you know if they have an audio guy?

I can ask, what's an audio board??

Pretty impressed by the camera, plugged it into a G4 PowerBook running
Tiger, it worked in ichat (including audio). Just got it working on my
MacBook Air running FreeBSD 11.1 using cuse4bsd-kmod, webcamd & cheese
from ports.

What application are you using to stream with?

Usually part of the PA system for the room. If you are lucky, the BCS, The Chartered Institute for IT may have assigned some A/V folks for the event. ( considering the venue, you may be in luck) The sooner you talk to them and ask about the audio, the better. You may be able to arrange an audio feed of the PA system. This is always the best audio solution. Just get the right audio adapters and feed the audio into the laptop line in, assign the line in as audio feed in the streaming software and you are ready to go. 


If audio feed is not possible, place the camera as close to the speaker as possible and angle it toward the slides. I use a clamp like this to provide a sturdy base for the cam:

If you have a proper camera tripod I believe you webcam has a threaded mount at the bottom. That solution would also work.

Great little work horse. Wrap it in a microfiber cloth to help keep the camera  lens fingerprint - free

So far I have only used the Adobe flash media encoder. There are other options but I would not be informed enough to get you up and running on them for Saturday. I will send you the settings we used with good results off list. 

https://offers.adobe.com/en/na/leap/landings/fmle3.html


I am exploring other options and will share them with you when they are ready. ( perhaps pkgsrcCon 2018?)

What has worked for me:
Do all your setups and make recording using the streams you plan to use the day of. (I have lovely 5 min videos of my Airbnb crash pad from BSDcan)

Get the FTP login info and pull down the test file when it has finished processing on the ScaleEngine system. This is usually an hour after you finish recording. 

Best of luck and be sure to publish the stream link on your con website and to this list if possible. 
I hope you found something helpful in this.

Hi Patrick,
Thanks so much for those details, I got in touch with BCS A/V team & 
indeed they have a line feed which I can just patch in. Haven't gotten 
back to me yet about whether that's going to be available tomorrow or 
not though :/

Following the video instructions on the scaleengine site I got both 
flash live media encoder & OBS connected to the service. I was then able 
to watch the RTMP stream directly on VLC.

I settled on OBS (Open Broadcast Studio) on OS X (video worked with OBS 
on FreeBSD but my Line input source is an external firewire soundcard, 
I'm happy not to fly the BSD flag on this occassion and avoid wrestling 
with things if I do get a line feed from the PA system (1) compile 
kernel with firwire support, 2) are firewire soundcards even supported 
on FreeBSD??)

My ghetto broadcasting station
https://pbs.twimg.com/media/DDlHHrBXcAEvCTv.jpg:orig

11" MacBook Air
SaffireLE firwire soundcard
firewire400 to firewire800 cable
firewire to thunderbold adapter
Logitech C922 camera
1TB external HDD with OS X El Capitan.

All ports loaded :)

Hello,
The schedule for the talks is up at the presentations section of the
site (times are in BST - British Summer Time)
http://pkgsrc.org/pkgsrcCon/2017/#presentations

If things go to plan, we should have a live stream of the event, thanks
to Allan Jude @ FreeBSD and Scale Engine.
There is a javascript video player embedded in a webpage here:
http://www.netbsd.org/~sevan/pkgsrcCon/stream.html

If the player doesn't work, you can point vlc to the following url by
selecting menu > open network stream:
