Ok. Creating /etc/unwind.conf with 

forwarder {X.X.X.X} 

where X.X.X.X is the IP address of the DNS server within the VPN,
and turning on unwind with

;rcctl enable unwind
;rcctl start unwind

does do something, in the sense that I get all the symbolic
names resolved. But can I tell what DNS server was asked for
the translation? --- so that I can check that it is the
local nameserver (as obtained from the local DHCP server)
that gets queried first and only when it does not know the
answer, unwind asks VPN DNS server (X.X.X.X above) for the
answer?

Re: midnight commander sftp problem after upgrade to OpenBSD 7.0

Dear list,


sorry for the noise, the sftp connection doesn't most probably work due

midnight commander sftp problem after upgrade to OpenBSD 7.0

[Rudolf Sykora]

Hello list,


I used to use the 'sftp connection' with mc, it worked, seemingly, until I
upgraded OpenBSD from 6.9 to 7.0. Now it says, when I try to use it:

 The requested method(s) are not currently supported (-33)

Does anybody know what could have happened (and whether it is related to

I just want to check if, perhaps, there is something new about the
possibility of the mentioned 'device passthrough' in vmd.

Regarding the option to improve usbtablet(4), I asked Frank Groeneveld,
the author of wacom drivers on OpenBSD, about that in 2017:

Is he right about the X mouse driver, or not? Ie., in the end, would it
be necessary to modify sth. else apart from usbtablet(4), or the
improvement in the latter would suffice to bring pressure sensitivity
(then I would perhaps try to modify it).

You might be right, however... I hoped that using smtpd would ensure
such things like solution for possible errors during sending, queueing
of mail when offline, etc (and the user mail agent would just pass the
mail itself, the name of the server to relay it to, and where to get
credentials from [or just pass them, too]). But, reading the answers,
it probably cannot be easily arranged like that.

(Btw., I am not against text-only user interfaces. I am writing this in
mu4e, though I am thinking even about mblaze tools [but that has its own
problems], or some plan9 [9front] tools. Unfortunately, a good solution
for email is still something out of my reach.)

thank you, as far as I can tell you understand me right.

In my case, my computer gathers mail from various mail services using
mbsync. I want to be able to reply the mail, but have the reply use the
mail server that is most suited for the reply. E.g., if I get an email
from school (downloaded from the school service), I need that my answer
is as if sent using the school service; similarly with my work mail,
etc. (The people at work want me to use their address when dealing with
work-related matters; it's then easily recognizable.) I thought the
program used to create a message does not have to know how to send email
(speak SMTP) but would just pass it to something that can (smtpd), to
relay the mail further. But for this I'd need that the server to be used
for sending be easily modified by user, as well as have some easy means
to supply the needed credentials.

relay email from users to per-user smtp servers

Dear list,


if I have several users, each of which wants to be able to send email to
generally different smtp servers with their own credentials, how does
one arrange such a thing? Can it be done easily without having a
separate rule in the system-wide /etc/mail/smtp.conf for each individual
user? Can it be done that they themselves can easily modify the smtp
servers information/credentials?

video capture / streaming

[Rudolf Sykora]

Dear list,


I'd like to stream video from my (usb-connected) camera via a web
server. The 1st I tried was to see if the camera works. So:

odin$ video
video: /dev/video: Permission denied
odin$ doas video
No protocol specified
video: cannot open display :0.0
odin$ xhost +
access control disabled, clients can connect from any host
odin$ doas video 
^Codin$

Ie, at last I saw an X window with the video. But is it possible to run
the video command as an ordinary user? (I had to doas...)

Next I want to stream the video via some kind of a server.
On the internet I saw people using 'ffmpeg' to serve the file somehow,
as well as using 'nginx' with the 'rtmp' module. Is any of this the way
how you would achieve the goal, or is it possible to use, say, the 'httpd'
server?

At this moment I know very little both about streaming and available
servers to do the job, and that's why I am asking for recommendation
based on some experience and knowledge.

Thank you for any comments.

Thanks! The freezing using a graphical emacs made me change to a
terminal emacs. The link seems relevant to me (I first tried to move to
the athena build [also because with GTK build there is some long lasting
bug when one runs emacs in its daemon mode], but no matter what, emacs
froze randomly at the very point the linked page discusses. So I will
try the quick fix (a hack, I would say); still, he only changes an
x-selection-timeout from 5000 ms to 10 ms, while my emacs froze (when it
did) apparently forever (ie, not just for 5 s).


Regarding the pinentry-emacs I now have yet another problem. 
When the pinentry prompt appears in one emacs frame (on one computer,
say at work), as it happens for me when the validity of the passphrase
has timed out, it blocks any other emacs frame. Ie, when I run
emacsclient -c from another machine, it freezes.

I tried a few things to no avail...


Thanks for any help.

Thanks for the link. Although it didn't help, I finally, by trial and
error, got my emacs to ask for the passphrase. In my case, I changed
~/.gnupg/gpg-agent.conf to just have:

allow-emacs-pinentry

inside, and in my .emacs I have:

(setenv "INSIDE_EMACS" (format "%s,comint" emacs-version))
(pinentry-start)

I have installed the pinentry package from M-x list-packages.  And then
(after
pkill emacs gpg-agent
) emacs started to ask me as I wanted.  I note that compiling and
installing the pinentry-emacs (or pinentry-tty) within the pinentry port
seems unnecessary. Furthermore, both lines in my .emacs seem to be
essential.  It's a pity I still do not understand how the chain really
works, but at least it works somehow now.

Hope it might help somebody in the future. I lost many hours with
such a trivial thing.

I tried pinentry-curses. Now I was able to try pinentry-tty,
too. However, with both I apparently have the same problem. The prompt
for passphrase is just thrown somewhere into the emacs window, and I am
not able to enter the password (emacs most probably doesn't know about
the request for passphrase, it tries to interpret keypresses as commands). 

I even tried to enable pinentry-emacs in the pinentry Makefile; it
is built. But when I choose it for the pinentry-program in

pinentry-tty in OpenBSD? to be used with emacs

[Rudolf Sykora]

Dear list,


I've been using mu4e to read email, and the passwords are read using
gpg2 and the gpg-agent (both 2.2.12). Nowadays I use emacs running in a
terminal (somehow any graphical emacs keeps to freeze randomly when I
use mu4e together with the org-capture feature; terminal emacs just
works). Until recently I used to ssh -X to my box to read email (and
used a graphical window to enter my passphrase), but now I would like to
use mosh instead (so that hibernating and waking up my notebook does not
interrupt the connection). But as mosh cannot be used for X forwarding,
I need to use a non-graphical means of entering a passphrase to
gpg-agent. On linux, I believe, there is a pinentry-tty program, but
that one is not available on OpenBSD. Also I found mentions of
pinentry-emacs. I tried to install the elpa pinentry package, added
allow-emacs-pinentry to ~/.gnupg/gpg-agent.conf, but whatever I tried, I
don't see any sign that it ever does something.  There is also a
pinentry-ncurses program available on OpenBSD, but that one seems to not
play well with my emacs; I see some prompt in emacs, but I cannot enter
the needed information.  Can anybody help me to get some way to enter a
passphrase to be relayed to gpg-agent inside emacs running in a
terminal?

I am using emacs 26.3 on OpenBSD 6.6.

Nobody spoke about "deliberately", or working in a "binary" way.
In the follow-up I added the information that the size of files can be
larger than 10 GB. In some systems (e.g. plan9) there are quite a few
limits/constants which lead, or can lead, to problems when
exceeded. That is what was meant by the settings.

problem to copy a (possibly large) file over a network device

[Rudolf Sykora]

Dear list,


I am able to copy a subtree 'www' with the command

; tar -cf - www | pv|  (cd ~ruda/tmp/test && tar -xpf -)

but I can't do the same with

In one terminal:
;tar -cf - www | pv | nc localhost 7000

In another terminal:
;nc -l 7000 | pv | tar -xpf -


[
I actually wanted to do a backup of the subtree with rsync over the
network, but that didn't work, spitting sth. like

rsync error: unexplained error (code 255) at io.c(820) [sender=3.1.3]
[sender] _exit_cleanup(code=10, file=io.c, line=820): about to call
exit(255)

I then tried to do the copying with nc, which again did not succeed; but
without any message this time, it just got stuck.

So I tried to copy just locally, within one machine, using localhost.
]

What one sees with the nc command is that the connection keeps existing,
but the copying itself stops. Ie., I can ctrl-c at the source end, and
the receiving command exits.

As I have no idea what can cause this behaviour, I am asking for any
help.

Thank you!

probable bug in openbsd chromium, at least in the stable package

[Rudolf Sykora]

Hello,

just starting chromium leads to a production of the following IP packets:
(
tcpdump -l -e ether host 18:03:73:25:3b:b6 and dst 224.0.0.251 |tee dat
)

11:17:26.587274 18:03:73:25:3b:b6 01:00:5e:00:00:fb ip 82: 224.0.0.251.mdns >

It's Chromium Version 73.0.3683.86 (Official Build) (64-bit)
distributed as a package in OpenBSD 6.5.

Such packets, with the source address of 224.0.0.251.mdns, should never
be produced. (RFC 1112, sec. 6.2: "The IP source address of the outgoing
datagram must be one of the individual addresses corresponding to the

What I didn't know was that the mode I asked about really is,
essentially, the vi editing mode, and, as such, has to be explicitly
turned on with 'set -o vi'. I wrongly thought there are 3 modes: emacs,
vi, and the one I asked about (the one described in the sh man page).


So, the short answer to my question would probabbly be: the commands
described in the mentioned section are relevant when the vi editing mode
of ksh is on.

chromium vulnerability?

[Rudolf Sykora]

Dear list,

https://thehackernews.com/2019/03/update-google-chrome-hack.html

claims there is a serious vulnerability in chrome.
I run stable 6.4, with the 69.0.3497.100p0 version, while they advice
upgrading to 72.0.3626.121.

What should I do if I want to stay on the stable branch and have a
secure (to the known point) browser.

(Apart from chromium I run firefox, which I try to keep up to date with

doas env
PKG_PATH=https://packages.rhaalovely.net/pub/OpenBSD/6.4/packages/amd64
pkg_add -u firefox-esr

but I guess there is nothing like this for chromium).

So do you recommend avoiding chromium until the next stable release of
OpenBSD, or what do you do?

(I also use "openup", but so far no upgrade for chrome has appeared
there).

Thanks for comments

wacom tablet settings? absolute mode?

The tablet then works basically as a mouse.
I wanted to switch the tablet to the 'absolute' mode (and perhaps
later change some of its other properties).
To this end I created a file /etc/X11/xorg.conf with the content
(I do not know if it is necessary to do it like this, nor I know
if what I do makes much sense)

Section "InputClass"

Option "Type" "stylus"
Option "Mode" "Absolute"
Option "Device" "/dev/uhid6"
EndSection

(The /dev/uhid6 I copied from somebody else. I do not know
why uhid6.)

I restarted X (do I have to?).
No change in behaviour at all.

I checked /var/log/Xorg.0.log if I can spot anything relevant.
It mentions /etc/X11/xorg.conf:

Can anybody explain to me what is wrong? I do not understand how the

decides which individual driver is eventually chosen for a device...

sshfs permission problem

[Rudolf Sykora]

Hello!

I run

doas sshfs syk...@pc109.fzu.cz: /home/ruda/mnt/fzu -o uid=1000 -o gid=1000

But then the mount point is owned (after the mounting) by root:

drwx--  1 root  wheel512 Aug  3 13:22 fzu

Hence I cannot enter the directory as the usual (and wanted) user 'ruda'.

1) doas chmod 777 fzu does not help (does nothing)
2) doas chown ruda:ruda fzu   gives permission denied

What can I do?

how to switch to a snapshot?

[Rudolf Sykora]

Hello,

I'd perhaps like to switch to a recent snapshot.
I read
https://www.openbsd.org/faq/current.html
but do not quite understand it.

If I download the snapshot (ie bsd.rd), boot from it, choose Upgrade
at the prompt, and upgrade any installed packages (??using pkg_add -u where
available, otherwise from updated ports??), do I still have to follow
those points described further down on the page, such as

2018/04/04 - PF_TRANS_ALTQ removed

etc.?

I'd expect I should watch for changes of syntax for configuration
files, right?

linux under vm on openbsd tutorial

please, is there some good (easy to follow, up to date)
tutorial about how to set up a linux distribution
under virtual machine on OpenBSD?

but as soon as I issue
rcctl start vmd
I get 'failed'

Re: fdisk MBR contains more than one OpenBSD partition!

[Rudolf Sykora]

> So please describe more in detail what kind of backuping you want.

I just want to regularly rsync /home to the "backup" partition
with some history (along the lines of

https://netfuture.ch/2013/08/simple-versioned-timemachine-like-backup-using-rsync/
).

This partition (or part of it) will later also be backed up to some
other machine.

The partition will be mounted read-only most of the time; only for
back-up it will remounted.

I would prefer that the backup partition be readable / mountable from
other machines. That's why I tried a separate MBR partition rather
than an OpenBSD disklabel one.

Re: mail sign/encrypt

[Rudolf Sykora]

> > I'd suggest Thunderbird + Enigmail

I want a small thing, hence Thunderbird is out.
Similarly, mutt does way too many things (it's not just MUA),
similarly (al)pine. (And both use ncurses, which I also
want to avoid).

For me mmh, mblaze or similar (eg. plan9 tools) is the way to go.
Even snail is way too complex.

So for now I sign and send email (prepared in message.txt) with this:

openssl smime -sign -in message.txt -text -signer sec/certCVUT.mycrt.pem \
-inkey sec/certCVUT.mykey.pem -certfile sec/certCVUT.caChain.pem \
-from rudolf.syk...@cvut.cz -to rsyk...@disroot.org \
-subject "HI" | sendmail -t

where certCVUT.mycrt.pem contains my certificate,
certCVUT.mykey.pem contains my private key, and
certCVUT.caChain.pem contains the chain of ca's.
All these can be obtained from the .p12 file using
appropriate openssl commands.

Thanks

mail sign/encrypt

So isn't there really any way to kill such a beast?

Hello,

I've been trying to use sshfs.

It started ok, but after a while the program
using it as if froze, in the console I see repeatedly

fusefs: libfuse vnode reclaim failed

The program at that moment can't be terminated,

The whole system at that point starts to be weird.
I was unable to kill sshfs even with -9. I was
unable even to reboot. I had to push the power

Dear Predrag,

I do read man pages. But 1) As far as I can tell, you will not find any
information anywhere about foomatic-rip (or any other smart filter)
when you just install the system, and 2), on a similar note, you can
only read pkg-readmes when you have the packages already installed.
I didn't know it all goes with the cups-filters package.

No.

not mention where to get it.

cwm window manager usage, hidden windows

[Rudolf Sykora]

Hello,

I've been trying cwm for a while and would like to
ask a question about it. As cwm seems to be developed
within openbsd, I dare ask here.

I seem to need desktops, thus my .cwmrc contains

sticky yes
bind M-1grouponly1
bind M-2grouponly2
bind M-3grouponly3
bind M-4grouponly4
bind MS-1   movetogroup1
bind MS-2   movetogroup2
bind MS-3   movetogroup3
bind MS-4   movetogroup4

which emulates desktops, and works fine
as long as one doesn't have hidden windows. My problem
with a hidden window shows, when

1) I have a certain group of windows,
2) I hide one window,
3) I switch to another group,
4) and I return to the original group.
Now the window that I hid is no longer hidden.
This I find annoying.
(The movetogroup unhides all windows.)

Is there any help (or does my use of cwm differ
from the usual use?)

Thanks for comments,

x clipboard that can copy images

[Rudolf Sykora]

Hello,

I need a program that would be able to "copy a .png file into
the clipboard", so that other programs (xournal, gimp, ...)
can paste the image.

I used xsel and xclip before, but these only work with text.
I tried to compile newer xclip, which can "copy images",
so far without success.
Apart from new xclip, bigger programs like copyq have
the ability to cope with images, but that's too big for
the task, I think.

Do you have any advice? What do you use?

Thanks
Ruda

generate xorg.conf

[Rudolf Sykora]

Hello,

please, how do one generate an xorg.conf file on openBSD?

I thought running
X -configure
(or X :1 -configure, if X is running)
would generate one, however, there seems to be no option -configure
present. So how, then?

(I want to read xorg.conf and then modify some parts to try to use wacom intuos3
tablet [pressure sensitivity].)

Thanks
Ruda

openbsd.org, openssh.com server(s) down

[Rudolf Sykora]

Hello,

is it only I who cannot connect to either
of openbsd.org and openssh.com, or
is the server down?

Thanks

I still haven't overcome this.
So is there any working way to mount locally a remote
filesystem (where all, the username, uid, gid are
different) and not run into permission problems?

Thanks

general xdg-open configuration

[Rudolf Sykora]

Hello,

I appear to need to modify the default application used
by xdg-open to open a file directory. The man page of xdg-open
is not very helpful. Can anybody tell me what is the right
and general (I run fvwm) system-wide file on openbsd to edit?

Thanks

ksh search history backwards patch still available

[Rudolf Sykora]

Hello,

does anybody have a patch described here

http://tech.openbsd.narkive.com/Ns42EcmB/patch-to-ksh-adding-history-search-backward-forward

which can be applied to the 5.8 release?
(direct use of the linked patch fails at a few places...)

Thanks

sshfs man page, -o idmap=user

[Rudolf Sykora]

Hello,

Yesterday I was trying to use sshfs.
I use the 5.8 release.

1)
The man page of sshfs says:

   mounting
   sshfs [user@]host:[dir] mountpoint [options]

   unmounting
   fusermount -u mountpoint

However, the fusermount command does not exists
on my system, contrary to sshfs, which got installed
using the sshfs-fuse package.

After spending some time to find fusermount, I
found that a simple umount works instead...

Shouldn't the man page of sshfs be changed to
state and reflect that?

2)
After putting
kern.usermount=1
into /etc/sysctl.conf and changing the rights
chmod 660 /dev/fuse0
I was then able to mount a remote filesystem, but
I ran into permission problems. Thus I tried
to add -o idmap=user into the command, which
results in immediate diconnecting:

$ sshfs -o idmap=user syko...@ssh.du3.cesnet.cz: mnt/du3
remote host has disconnected
$ sshfs syko...@ssh.du3.cesnet.cz: mnt/du3 -o idmap=user
remote host has disconnected
$ sshfs syko...@ssh.du3.cesnet.cz: mnt/du3
syko...@ssh.du3.cesnet.cz's password:

The -o idmap option is documented in the map page
and I use a command like this on Linux.

Do you have any comments or can you help?


Thanks!
Ruda
