Re: Firefox hangs after sleep

[Raymond, David]

I reinstalled OpenBSD on the laptop experiencing this problem (for various
reasons) and the Firefox problem went away.(!)

Firefox hangs after sleep

[Raymond, David]

At some point (I can't put my finger on exactly when this started), an
existing firefox instance hangs after my laptop is put to sleep and then
wakes from sleep.  Websites in existing tabs still work, but searching for
another webpage in an existing tab or opening a new tab is when the hang
occurs.  Killing and restarting firefox eliminates the problem until the
next sleep.  Interestingly, "simple" websites such as the OpenBSD or Arch
Linux websites still can be started after sleeping, but "fancy" ones such
as Gmail or the Washington Post cannot.  This suggests to me the problem
lies in javascript or some other non-pure html component.

I am using 7.4 stable on a Lenovo X1 Carbon, gen 4, though it also occurs
on an X1 gen 9.  A recent update to firefox (and all the other installed
packages) didn't help.  This doesn't happen with other browsers such as
chromium or iridium.  I am not sure what kind of diagnostics would help
here.

Firefox hangs on sleep

[Raymond, David]

I noticed for the past week or so that firefox hangs on return from a sleep
on my Thinkpad X1 Carbon version 4.  This is true on both 7.3 and 7.4
stable.  Other processes eg chrome, epiphany, don't.

Not sure what additional info to provide.

Re: Shotwell

[Raymond, David]

Rafael,

Thanks for replying about this.  I have already set the permissions
and uploading pictures to shotwell (which apparently uses libgphoto)
used to work.

However, I discovered a workaround.  On the phone when setting up the
usb connection, first click "no file transfer" then click " file
transfer" and shotwell then loads the pictures. This may be a
peculiarity of Pixel phones or Android 13 which libgphoto doesn't
understand -- some initialization issue.

Shotwell

[Raymond, David]

Hello,

I am trying to import photos using Shotwell over a usb connection with
the file transfer option. When I connect my phone to the usb port with
Shotwell running and select this option, Shotwell recognizes the phone
but says that there are no photos to transfer.  The transfer works on
Arch Linux.

Am I missing something?  Some kind of permissions?  The phone is a
Pixel 7 and I am running openbsd 7.3 stable.  I had the problem with
7.2 as well, but things worked before (I think with an earlier pixel
phone).

Re: error rebuilding binaries after 6.9->7.0 sysupgrade

[Raymond, David]

So, to clarify, if I upgrade to a snapshot after upgrading to 7.0
stable, what happens when 7.1 stable comes along?  Can I get to that
stable release from a previous snapshot?

Re: No firefox on OpenBSD 7.0 i386?

[Raymond, David]

I use epiphany quite a bit, and like it a lot, though there are
websites on which it crashes.  It uses the same toolkit as midori and
in my opinion has a somewhat better user interface.  Don't know
whether it works on i386 at this point.

Importing files into shotwell

[Raymond, David]

I tried to import a .jpg file into shotwell from the file system, but all
files (as opposed to directories) are grayed out and inaccessible in the
shotwell import menu.  Is this a bug or a feature?

I'm using an up-to-date stable 6.9 version of the os with shotwell-0.30.11.

Re: Suspend/resume does not work on Lenovo X1 Carbon 3rd gen laptop

[Raymond, David]

Hi Mark,

I checked my gen 4 X1 Carbon and it has both TPM and AMT, though I
have AMT turned off in the bios.  I also have secure boot turned off
so I don't have to mess with TPM stuff.  Suspend/resume has always
worked fine on this machine in obsd 6.6-6.8.  I have never used gen 2
or gen3 X1s, though as I mentioned, the gen 1 version also works.

Re: Suspend/resume does not work on Lenovo X1 Carbon 3rd gen laptop

This is odd, as I have 3 X1 laptops, gens 1, 4, and 5 and
suspend/resume works fine on all of them.  However, I am still on
openbsd-6.8.

Re: home printer

[Raymond, David]

I use an HP Color Laser Jet Pro MFP M283fdw on OpenBSD and it works
well with cups.  The generic postscript driver works with it on cups,
so openbsd lpd should work as well.  HP also has some cheaper
monochrome laser printers in the same line.

Re: chromium has troubles showing videos from youtube

[Raymond, David]

Regarding youtube videos on chromium, I had the same problem on the
epiphany browser.  The solution in that case was to install optional
gstreamer packages.  I don't know if all of these are required:

gstreamer-0.10.36p13 framework for streaming media
gstreamer-ffmpeg-0.10.13p16 ffmpeg element for GStreamer
gstreamer-plugins-base-0.10.36p19 base elements for GStreamer
gstreamer-plugins-good-0.10.31p26v0 good elements for GStreamer
gstreamer1-1.18.0   framework for streaming media
gstreamer1-plugins-base-1.18.0 base elements for GStreamer
gstreamer1-plugins-good-1.18.0 good elements for GStreamer
gstreamer1-plugins-libav-1.18.0 ffmpeg elements for GStreamer

Maybe chromium has the same issues.

filters in OpenBSD in printing

[Raymond, David]

Questions about lpr printing:

I tried putting a filter that drives an HP Deskjet printer (works with
lprng on linux) as an output filter in printcap and it didn't work.
Would it be more proper to put it as an input filter?  I am still on
version 6.7 of the OS.  (I saw a recent post indicating that changes
were made to the lpr system in 6.8.)

One of the problems was that I couldn't get rid of the banner page
even though the appropriate flags were set.

I have looked for lpr documentation more informative than the
lpr/lpd/printcap man pages, but I haven't found anything.  The
printcap page describes some really archaic filters, but not much that
is helpful in today's world.

I am currently using cups but would like to get rid of it, because if
their set of filters doesn't do the job, you are stuck.  (Plus other
hair-pulling frustrations.)

Re: OpenBSD X support for big resolution monitors

I am running openbsd on a laptop with 2560x1440 pixels and X11 handles this

Re: Help, i want to ask if my Asus Vivobook Ryzen 3 , Vega 3 can run openbsd

I run Vega 3 graphics on desktops.  There are a few quirks, the most
important being to turn off the hardware cursor.  If I read the
upgrade notice for 6.7 correctly, the cursor problem may be fixed in
that version.

Don't know about wireless.  You may have to get a usb wireless dongle.

I had terrible (but ultimately solvable) problems associated with the
bios getting linux to work on a Thinkpad E series which runs on AMD
cpu/graphics.  Hopefully ASUS doesn't have the same problem.

Best of luck!

Re: dynamic dns updates for clients in my home network?

I use dnsmasq (an openbsd package) on the gateway for my lab ethernet
network and it works great with minimal configuration as a local DNS
server.  At home I have a Synology wireless router which does the same
as long as you tell it to make DNS reservations.  Your mileage may

I noticed that chattr exists on OpenBSD.  The man page says it applies

2. If not, is it of any use on OpenBSD?

Re: GNU+Linux corporate takeover, was: Wine for OpenBSD?

[Raymond, David]

Amen to all that.  Arch Linux worked for me for many years, but the
Arch philosophy of adopting bleeding edge software has become
increasingly difficult to deal with, given the corporate takeover of
Linux.  Started out with BSD in the early days, moved to Slackware,
Debian, and then Arch.  Finally got fed up and explored the major BSD
derivatives and OpenBSD was the only one I found where things just
work (most of the time!).

Kudos to Theo and everybody involved.  I try to help where I can,

Re: Iridium vs Chromium

[Raymond, David]

My problem with iridium is that it is based on an older version of
chromium and I am not sure that they keep up with inevitable flow of
security fixes.  That said, I am a bit nervous about OpenBSD's lags in
keeping up with browser security fixes.  (I'm not criticizing -- I
understand that OpenBSD is a small operation without the people needed
to keep track of non-core packages.  And I just converted from Arch
Linux, in which the storm of updates and resulting incompatibilities
drove me crazy and contributed to my shift to OpenBSD.  Still, I am a
bit nervous about even slightly out-of-date browsers at this point and
I am not sure that iridium is an improvement in this regard.)

I have compared the console and ttyC* entries in /dev/ with a

Disabling AutoAddDevices  in an X11 configuration file snippit didn't
help either.

Any pointers on where to look to fix this problem?

X11 fails to start on Zotac box

[Raymond, David]

I am trying to get X11 working on a Zotac box with a quad core Celeron
processor, ZBOX-CI323NANO with "Intel HD graphics" (no further info).

No dice.  Starting xenodm from boot results in a hang with a blank
screen.  Running startx after boot produces some output to stderr and
an Xorg log file entry.  I am attaching both and the dmesg output.

I noticed the entry in the log file

but I am not quite sure what to do about it.

Re: Help: System hang/Lockup using snapshots on Intel i5 NUC?

You might try an alternate desktop/window manager such as lxqt or
icewm and see if the problem persists.  When I tried XFCE on my X1

Re: What TERM fixes Emacs?

[Raymond, David]

On my X1 Carbon running openbsd 6.6, the console works fine with the
non-X version of emacs except that the meta key is not set.  One can
emulate the meta key by typing escape followed by x, but this is a
pain.  Maybe there is some mechanism for setting the alt key to meta
in emacs on consoles, but I use X11 so I haven't needed to pursue
this.

Same story on the virtual console window on a vga monitor attached to
a desktop with 6.6.

Purging a wifi connection

[Raymond, David]

I have a problem when I have two wifi services available, say, a hotel
wifi and my cellphone hotspot.  Suppose I put the hotel wifi in my
hostname.xxx file and run sh /etc/netstart and I don't like the
results.  Removing the hotel wifi from the hostname file, replacing it
with my hotspot wifi, and rerunning sh /etc/netstart results in the
computer trying to connect with the hotel wifi again, even though this
connection is no longer in the hostname file.  If I then reboot the
computer and rerun sh /etc/netstart, it connects with the hotspot wifi
as desired.

My question is whether there is a way to purge the non-desired wifi
connection without rebooting the computer.

Re: suggestions for USB printer (maybe even with scanner)?

[Raymond, David]

I have had good luck on OpenBSD with a variety of HP printers using
the hplip package and cups.  (To use the latter, put /usr/local/bin
before /usr/bin in your PATH to avoid confusion with lpr programs.)
The xsane package does scanning on HP printers that have this
function.  I have connected them mainly via the network, but I don't
see why direct usb connections wouldn't work as well.

Realtek ethernet connection failing

[Raymond, David]

I am running beowulf network of openbsd machines with Realtek ethernet
chips.  I get very occasional failures that bring the whole
calculation down. The connection is dropped and a ping to the problem
machine returns nothing.

I can connect directly to the machine in question however.  Doing an
ifconfig shows that re0 is still UP.  However, in dmesg, there are two
"watchdog timeout" messages for re0.   Running ifconfig re0 down
followed by ifconfig re0 up brings the network back up.

Sorry, I can't include the dmesg directly in the text due to the
nature of gmail, but I am including the dmesg text as an attachment.
Some of the possibly relevant entries are as follows:

...
re0 at pci5 dev 0 function 0 "Realtek 8168" rev 0x15: RTL8168H/8111H
(0x5400), msi, address 70:85:c2:ac:e4:4b
rgephy0 at re0 phy 7: RTL8251 PHY, rev. 0
...
re0: watchdog timeout

Re: SSIZE_MAX

[Raymond, David]

Thanks, that is helpful.

It is now clear to me that the default on OpenBSD for SSIZE_MAX is
2^31 - 1 or greater.  However, I still run into problems on writes to
a TCP/IP socket with sizes exceeding something like 32000 bytes
(probably 2^15 -1).

Is it possible that TCP sockets have a smaller SSIZE_MAX or could this
be a bug?  I am handling partial reads and writes correctly as far as
I can see.  Chopping big writes into chunks smaller than 32000 seems
to solve the problem.

Re: SSIZE_MAX

[Raymond, David]

Hmm

Thought I found a 2^15 -1 version of SSIZE_MAX in the includes, but I
guess I was mistaken.

The real issue is whether doing write(2) to a TCP/IP socket bigger
than 2^15 - 1 bytes causes problems.  I am not very experienced in
this area.

SSIZE_MAX

[Raymond, David]

I am confused about SSIZE_MAX and read(2)/write(2).  The POSIX
SSIZE_MAX is something like 2^15 -1.  This seems to be a real
limitation when writing to a TCP/IP socket, as I learned from
experience.  However, much larger reads and writes seem to be possible
to files and UNIX sockets (pipes).  This makes me uneasy, given the
warning in the man pages for read(2)/write(2).

Any insight on this topic would be appreciated.

Re: What is you motivational to use OpenBSD

[Raymond, David]

Why do I like openbsd?

I used linux for several decades and it has become harder and harder
to keep up with gratuitous changes and to keep my 20+ machines running
and updated.  The last straw was usb mounting being broken in the
linux kernel for 6 months.  Really!  The whole linux enterprise seems
to be spinning out of control as it gets jerked around by commercial
interests.

OpenBSD is easy to install and use and retains some of the delightful
simplicity of early days UNIX.  I can mostly get done what I need to
get done and I am working on the rest.  The emphasis on security in
this increasingly hostile digital world is certainly a plus as well.

Odd /tmp behavior

[Raymond, David]

On an AMD-64 workstation /tmp fills up to 105% according to df,
apparently as a result of UNIX pipes in a shell script passing a whole
lot of moderately big files. Examination of /tmp with du and ls -gal
on /tmp shows no big files and trying to delete everything that is
there has no effect.  Rebooting cleans out /tmp.

I had /tmp mounted with the standard options + softdep.  I eliminated
softdep and the problem appears to have gone away.

Any ideas on what is going on with softdep here?  Dmesg shows a long
series of "/tmp file system full" messages.

Re: Readv and writev failing across ethernet

[Raymond, David]

Well, I figured out how to suppress the readv/writev problems in
openmpi -- run it under ktrace!  I gave up after the ktrace file
reached 46 GB.

This suggests that the "not permitted" failure on writev is a timing
problem that appears sporadically.  From what I have read about
openmpi, a new socket pair is opened for every high level write.  If
the write tries to transmit before the read socket is established,
then the write will fail with this message.  So, if some rare event
delays the establishment of the read socket, the write fails.  This
only happens in my case in going from one machine to another, not
between processes on the same machine, which kind of makes sense.  I
have tried three different ethernet cards (realtek, broadcom, and
intel) and all do the same thing.  The problem maybe isn't even in the
ethernet but somewhere higher in the stack, as suggested by Philip
Guenther.

I am currently writing a tiny openmpi replacement in Go for the small
part of mpi that I actually use.  I should be able to explore this
issue further and maybe even make my model work.

Re: dhcpd and unbound on a small LAN

[Raymond, David]

I found unbound hard to use so I went back to dnsmasq (a package on
OpenBSD), which I had used previously on linux.  Trivial configuration
and it works like a charm in providing DNS service for local and
remote systems behind a NAT firewall. (It gets local information from
the host file on the NAT machine.) Optionally, it will also provide
dhcp service.  (Note that you have to set up a _dnsmasq user/group to
keep rcctl happy.)

Re: Readv and writev failing across ethernet

Openmpi uses readv/writev.  I am beginning to think that the timeout
and permission errors are legit and reflect real conditions.  What
does re do when it receives a write request when it is busy?

I am having some luck in redoing writev calls when needed, though
there are still some problems.

Re: Readv and writev failing across ethernet

[Raymond, David]

The "timeout" error was numerically 60.  Curiously, boards with RTL
8111GR chips did not produce these errors, but those with RTL 8111H
chips did.  Unfortunately, this chipset seems to be in a lot of newer
motherboards.

I didn't use ktrace/kdump.  The openmpi software returned the error
presented by readv/writev.

It sounds like the simplest solution at this point is to try
non-Realtek pcie network cards.  Any suggestions?  How are Intel or
Broadcom cards?

Readv and writev failing across ethernet

[Raymond, David]

I am running openmpi-4.0.2 (self-compiled with GDS patches) on
up-to-date 6.6 stable with a Go program that calls Clang MPI routines.
With particular hardware (details provided if desired), readv and
writev calls randomly fail with respectively "Timeout" and "Permission
denied" errors for calls from one machine to another across the
ethernet.  The errors don't occur between cores on the same machine.
The man pages for readv and writev don't document the possibility of
such errors.   Modifying the MPI code to retry readv and writev
doesn't help.

Any ideas on what is going on here and how it could be fixed?  The
problem doesn't occur with Linux, but I would really rather stay with
OpenBSD.  Details can be provided as needed.

Re: [UPDATE] devel/openmpi 4.0.1 -> 4.0.2

[Raymond, David]

Martin,

I have been using openmpi 4.0.2 on my computer system and I found a
bug that is provoked by running a job (a Go program interfaced to the
Clang MPI package) on multiple machines connected by ethernet.  This
crashes the program with the following output:

--
plover:~/src/models/goconv$ mpirun -np 2 -hostfile hlist
/home/raymond/bin/goconv032 plist

orted:/usr/local/lib/pmix/mca_gds_ds21.so: undefined symbol
'pthread_mutexattr_setpshared'
ld.so: orted: lazy binding failed!
Killed
--
ORTE has lost communication with a remote daemon.

  HNP daemon   : [[62306,0],0] on node plover
  Remote daemon: [[62306,0],1] on node gryphon

This is usually due to either a failure of the TCP network
connection to the node, or possibly an internal failure of
the daemon itself. We cannot recover from this failure, and
therefore will terminate the job.
--
plover:~/src/models/goconv$
-

I traced this to the fact that OpenBSD's version of pthreads doesn't
have "pthread_mutexattr_setpshared".  It turns out that the
configuration file undefines a flag if this is so, but the actual code
doesn't pay any attention to this.  I fixed the problem by putting
appropriate ifdefs around the code generating the error, which itself
is simple error checking code.  This seems to work.  I have attached
two patches for the 4.0.2 source.

I'm not sure that the diffs are done quite right, but they do fix the
problem using patch < mypatch in the main directory.  (I do my patches
after yours, but I don't think that this is important as the two act
on different directories.)

Dave

X11 on VEGA graphics

[Raymond, David]

I have tried out VEGA graphics on Version 6.6 stable.  Out of the box
it mostly works, though there are two oddities:
1. The cursor for resizing windows (under openbox and icewm both) is
wrong and misplaced, though the resize can be done.
2. Upon logging out of icewm, the confirmation screen has text
missing.  Very odd, this doesn't seem to occur anywhere else.

I found the following fixes: For (1), turn on the software cursor.
For (2), going to 2-D DRM alleviates but does not completely fix the
issue.  The remaining problem is that a small white rectangle overlays
part of the confirmation screen.

To implement these changes, the following file (10-amdgpu.conf) is
placed in /etc/X11/xorg.conf.d:

ection "Device"
Identifier "AMDgpu"
Driver "amdgpu"
Option "SWcursor" "true"
Option "DRI" "2"

Softdep and noatime

[Raymond, David]

I am switching to OpenBSD from Linux and I have questions about the
use of softdep and noatime in mounting disks.  I have a variety of
systems with a mix of SSDs and rotating disks.

Softdep seems to have some advantages in speeding file access, but it
is not the default.  Are there any downsides in using softdep?

On SSDs in particular, is it worth setting noatime to reduce the
number of disk writes?

Re: T430 power draw unexpectedly high

[Raymond, David]

I don't know whether this is pertinent, but I have a Lenovo X1 Carbon
(gen 4 I think) which ran the fan at full speed under Linux.  A bios
update solved this problem.  I have converted to OpenBSD (6.6 stable)
and the problem has not reappeared. It might be worth checking with
Lenovo to see if a similar problem/solution exists for your machine.
Bios updates are easy to install on Thinkpads.

Re: Home NAS

[Raymond, David]

I don't know how current tape systems are, but I have been burnt by
them in the past.  Either the tape deteriorates or the tape writer
company goes out of business.  My current approach is to keep stuff I
want to keep on current online storage in multiple places plus offline
USB.  Data get migrated to new media as they appear and prove
themselves.  There is still the possibility of undetected bit rot
however...

Re: Home NAS

[Raymond, David]

I have done similar things on Linux for years and am now doing them on
OpenBSD.  Sounds like what you want to do can be done with a simple
rsync script.  OpenBSD ffs (ufs) should be stable, it has been around
for decades in various incarnations.  I have never noticed bit rot in
this system, though I imagine it could happen if a disk is gradually
going bad.  That's why multiple backups help.  You might want to set
up a raid5 backup, as this detects parity errors.  More complicated
though.  One weakness in such as system (ask me how I know!) is that
if the NAS goes gradually bad, the errors will propagate to the
backup.  Using rsync without the --delete option most of the time
alleviates this somewhat.  Only run with --delete when the backup
starts getting full and you are confident that your NAS drive is ok.

Re: Raid0 max volume size

Hmmm

On install of openbsd a second, non-boot 4 TB disk was initialized by
fdisk in the usual way.  My intention was to create a single partition
and file system for the whole disk.  However, disklabel limits me to a

Re: OpenBSD and solid state disks

[Raymond, David]

Thanks for the insight on SSDs -- sounds like there is not much of an
issue with modern drives.

Re: Tools for writers

[Raymond, David]

You might try lyx.  This is a front end for latex.  You can write
without worrying about formatting and come back to that later.  Also,
when you do the formatting, you don't have to worry about niggling
details as in word and its clones.  Just declare chapters, sections,
etc.

Lyx is an OpenBSD package.

OpenBSD and solid state disks

[Raymond, David]

I recently installed OpenBSD on a Lenovo X1 Carbon with a solid state
drive and it works great.

My question is whether OpenBSD addresses the special characteristics
of solid state drives, especially those having to do with longevity
and reliability.  I can't find anything written on this.  Linux has
certain means for addressing this issue, such as fstrim as well as
various kernel options.  Is there anything I have missed with OpenBSD
on this subject?
