What if they are brave enough to decide to work elsewhere? A place
of employment without intentional flaws in interview questions for
example.

I found this note confusing, because I was able to make changes and see them 
reflected without running newaliases(8). However, I believe this is because 
you only need to run newaliases(8)/makemap(8) if you are using a db table.

newaliases vs makemap

[Scott Vanderbilt]

In /etc/mail/aliases, there is the following note:

#   >>The program "newaliases" must be run after
#   >> NOTE >>  this file is updated for any changes to
#   >>show through to smtpd.

Yet the man page for newaliases(8) says:

    Note: this utility is provided for sendmail compatibility. The 
preferred way of rebuilding the database is withmakemap(8) 
:


# makemap -t aliases /etc/mail/aliases

Taking the note in the man page at face value, I would expect that the 
note in /etc/mail/aliases is now out-of-date, is it not? Or am I 
overlooking something?


Thanks.

rying to get meta-data configured for cloud-image VMM instances

[Ax0n]

I'm hoping someone on-list has actually gotten this to work and can point
out where I'm going wrong.

I've been trying for months off and on to get this to work. I have a
feeling I just don't understand the documentation for meta-data (
https://github.com/reyk/meta-data ) though I see at least one httpd.conf
anachronism in the documentation. "Strip" isn't allowed in the "root"
definition of httpd.conf, so httpd won't even start with this chunk of
config:

server "meta-data" {
listen on 169.254.169.254 port 80
fastcgi socket "/run/httpd.sock"
root { "/", strip 1 }
}

I've removed ", strip 1 " from the httpd.conf, so my whole config looks
like this. N.B. This may be my actual problem, but I don't know how to
solve it.

ext_addr="*"
server "default" {
root "/htdocs/"
directory auto index
listen on $ext_addr port 80
}

# Include MIME types instead of the built-in ones
types {
include "/usr/share/misc/mime.types"
}

server "meta-data" {
listen on 169.254.169.254 port 80
fastcgi socket "/run/httpd.sock"
root { "/" }
}

I've otherwise installed meta-data as the instructions say, and started it
with this command-line:

doas kfcgi -r -n 2 -u www -p / -- /usr/local/libexec/meta-data

The meta-data directory structure is as follows:
[axon@transient ~]$ find /home/vm/meta-data/ -type f
/home/vm/meta-data/vmmbuntu/instance-id
/home/vm/meta-data/vmmbuntu/username
/home/vm/meta-data/vmmbuntu/public-keys/0/openssh-key

Where instance-id contains "vm1", username contains "puffy" and the
openssh-key is the public key for this laptop I'm running on.

I downloaded xenial-server-cloudimg-amd64-disk1.img and converted it to raw
with the qemu-img utility. I also made a 10GB image that I intended to
install some stuff permanently to (ubuntu.img)

I then started the vm like this:

doas vmctl start vmmubuntu -d xenial-server-cloudimg-amd64-disk1.raw -d
ubuntu.img -n local -m 2G -c

pf(4) queuing and interfaces

[David Higgs]

My wireless AP puts traffic from each WiFi network (trusted, guests,
etc.) into a separate VLAN, which are then picked up by my OpenBSD
router and filtered appropriately via pf rules.

In other words:
  em1 is for untagged traffic to the AP itself
  vlan100 has parent em1 and is for my "trusted" WLAN
  vlan200 also has parent em1 and is for my "guest" WLAN

pf.conf includes the following line:
  queue wlan_q on em1 bandwidth 50M max 50M flows 1024 qlimit 1024 default

When I specify only the queuing rule as shown above, is traffic sent
on vlanXXX also receive this queuing policy?

If not, should I divide the physical bandwidth between logical
interfaces?  Does FQ-CoDel work correctly if they are each assigned
the full physical bandwidth?  Or should I be dividing one or both of
the configurable interface rates?

And lastly, if I define a queue as below - does this expand into two
different queues with the same name or one queue with bandwidth shared
between two interfaces?  Running "pfctl -vsq" indicates the former,
but I'd like to be sure.

  queue some_q on { em2, em3 } bandwidth 95M max 95M flows 1024 qlimit
1024 default

Thanks.

Stockholm anoncvs rsync mirror not updating

[Andreas Kusalananda Kähäri]

The anoncvs rsync mirror at

rsync://anoncvs.eu.openbsd.org/OpenBSD-cvs/

seems to have stopped updating.  This has happened before when the
cvsync (?) on the mirror fails or gets stuck.

I sent a message to the maintainer this morning, but I thought I'd just
mention it here too.

Andreas

Re: Employers, Jobs and OpenBSD

Spot the candidate that is aware of common standards, is brave enough to come 
forward saying that the test is flowed (we ask to write /var stuff inside 
/usr), and returns the POSIX-compliant solution, citing the standard.

A test example that comes to mind is writing /var content into /usr.
Many people in this list would not get a job.



What is a purpose of such test and what is expected to be proved by this 
operation? Just curious, nothing more.

If someone is cocky about a certain unix-like OS on their CV but is unable to 
adhere to the standards while also using other unix-like OSs, they are shown 
the door where they came from.

A test example that comes to mind is writing /var content into /usr. Many
