Is there the ability to read and write raw RAM contents?

[Z Ero]

I understand this would be a severe security/stability issue in many
cases but for some applications it would be interesting/useful if one
could dd and grep, etc, RAM on a live system. Is there any way to do
this on OpenBSD? Or is program memory space read write access always
protected by the kernel in every instance?

Reading suggestions for running graphical X based Linux applications on OpenBSD using a Virtual Machine?

[Z Ero]

This should be possible, correct? I understand that vmd does not
currently support VGA output inside the VM but but I should be able to
run a headless Linux instance in a VM image hosted on OpenBSD vmm and
then pipe the graphical output over the virtual network interface to a
display on the OpenBSD host system. For example if I want to run the
Linux version of Mathematica this way that should be possible,
correct? Does anybody know of a configuration tutorial in this area?

Thanks...

Live ACPI "Hibernate" Style Snapshot possible without Powering Down?

[Z Ero]

Hello,

Curious if there is a facility to save system memory state to disk for
recovery such as is done the ZZZ (hibernate) command without actually
powering down? Could be useful to return to a previous active memory
state for devices that are not on UPS or not closely monitored but do
preform non-scripted batch work.

So, for example if there is a transient power interruption on
03-05-2019 at 12 AM the device could be configured just to reboot to
the state it was in at 03-04-2019 at 12 AM where it was doing similar
work. I don't mean load a file back up but reload a previous active
memory / process state as if returning from hibernate.

Thus to enable this hibernate style dumps would be saved periodically
by cron for example.

I understand that for some dumping active memory to disk without
powering down might present a security concern but this is not a
problem for my application.

Thanks

Java program question

[Z Ero]

Hello,

I am trying to run the stand alone Java program cgoban.jar found at
https://www.gokgs.com/ for playing the board game "Go."

I very rarely run Java programs these days.

OpenBSD only seems to offer jamvm for a virtual machine and for
whatever reason that does not work with this program.

This is not a browser applet but a program you download and use
outside a browser by running on a Java VM to connect to their servers.
They used to offer a browser applet many years ago but now just offer
the stand alone program.

Any suggestions?

Thanks...

[Z Ero]

Hi Stuart,

Thanks for the respectful reply. I am a little bewildered by the
degree of unwarranted hostility the original post met, but whatever,
when in Rome... I believe as of now most commercially available small
business or home LAN routers / WAN gateways are 32 bit MIPS or ARM
based (as opposed to enterprise, c.f. the 64 bit MIPS Octeon Edge
Router). I understand your comment about the larger 64 bit address
space being more secure because it is such a vaster space better able
to be randomised, but I am not sure how much this really matters
practically. For example, have journal studies shown that in the real
world 32 bit routers are actually hacked or 'pwned' at a higher rate
(after accounting for market share) than 64 bit based machines?

Hello Stuart,

Yes it is correct that the Intel atom is 32 bit i386. Just out of
curiosity why would you not recommend it for a router / internet
appliance application? Not everybody needs 10G Ethernet or AC wifi on
their home or office LAN. Is it a security issue, a performance issue,
or a lack of developer attention issue (i.e. there are more eyes /
there is more focus on the 64 bit code base than the 32 bit code base
at this time)?

Here is the Intel info on these N280 processors in these thin clients.
https://ark.intel.com/products/41411/Intel-Atom-Processor-N280-512K-Cache-1_66-GHz-667-MHz-FSB

If it is a perfomance issue I beg to differ. This machine more than
capable for normal LAN use for a home or small business assuming one
is not generating massive continuous traffic. Compare to microtik
routers, for example. Many if not most routers are 32 bit MIPS based
even today. If it is a security issue due to W^X or something about
memory / execution protection are there not similar issues on other
platforms used in routers such as MIPS or not? If your firewall rules
/ open ports are prudent shouldn't that prevent remote execution
anyway? Is the Atom effected by Meltdown?

I use this machine myself as my home router, although I guess maybe
that is not saying much because I also use a ten year old Thinkpad as
my daily driver machine...kind of stuck in 2008 I guess lol. But I
really don't think most home or business applications really need
anything more than 1G ethernet or 802.11n wireless it is like 1080p vs
4k in HD TV. At a certain point the marginal returns to increased
capability diminish, and diminish at an accelerating rate.

Last year I was using a 128mb RAM 200 mhz Soekris based router. I
could watch HD Youtube videos on that without issue.

Selling things through the mailing list allowed? I have compatible THIN CLIENTS for Firewall / Router appliance use Available

[Z Ero]

I am trying to clear out some things I have in my basement. I thought
these may be of interest to the OpenBSD community so I am mentioning
them here. Not trying to spam or distract anybody...

I have a bunch (about 50) of atom based HP T5740 thin clients that
work great as an OpenBSD based VPN gateway, router, firewall, print
server, wifi or other network appliance. I have the expansion modules
for these clients as well and Intel or Broadcom dual NIC cards. So
there are a total of 3 gb LAN ports. Additionally these thin clients
have a miniPCI express slot. I have antennas and OpenBSD compatible
Atheros AR5B95 cards. So these machines can be configured as a stand
along Wifi router or AP. Privately email me if interested.

Here is a overview of the client
http://www.parkytowers.me.uk/thin/hp/t5740/index.shtml (not my site).
I may have my own site up soon, depending on what else I have to do.

In addition to the thin clients I have

(1) a bunch of 2GB PC2-6400S modules of DDR2 SODDIM PC2-6400S laptop
RAM available, if anybody is still running an older laptop such as a
Thinkpad.

(2) a bunch of laptop wireless cards including Atheros and Intel cards
that tend to work well with OpenBSD

(3) a lot of Thinkpad T60 / T61  / R61 hardware parts.

(4) about six Thinkpad T60 / T61 / R61 machines which run OpenBSD
flawlessly and are fully capable of being daily use machines if your
use pattern is mainly on line or over SSH along with word processing
and business productivity tasks and basic image management and
manipulation.

[ I use OpenBSD on an dual core 2.0 ghz Thinkpad X61 notebook daily,
with 6GB of RAM (max capacity 8GB) and I find this machine is able to
do everything I need it do. If I need something more powerful, such as
to compile large software quickly I can just run a VPS in the cloud. ]

Payment to be arranged privately through Paypal, cryptocurrency or
cash in mail. Shipping included in prices for USA buyers, if
international, buyers must be willing to pay for shipping.

If such solicitations are not allowed through this mailing list then I
apologize. I won't do it again.

Atheros ATH9485 in athn

[Z Ero]

Can any one give an idea as to the work required to get support for

bunch of 225s and 125s that I would like to use with Openbsd but I see
this chipset is not currently supported by the athn driver. I guess
FreeBSD and Linux support it.

Re: kernel relink segfaults on ALIX

[Z Ero]

Coincidently I just logged in to write the misc  list about relinking
on boot. Is it possible to disable it? What about just relinking on
the first boot after install? So then every kernel image is different
but not re-randomized each boot! There are some low memory / slow CPU
embedded systems like Alix / Soekris where the benefit, in my opinion,
of re-linking every single boot is not worth the cost. That said
granted these systems should not be rebooted frequently anyway once in
production during normal use. I had a soekris recently that performed
well for the task I needed it for but that I chose to install OpenBSD
version 5.8 on...because I did not want to put up with the
relinking...I would have rather used 6.2...would it be possible to
give users a "switch" to turn off relinking if they want without
recompiling the kernel...please forgive my ignorance (or flame
away...) if this already exists.

Thanks.

Atheros AT5424 (ath) issue on 6.2 (amd65)

[Z Ero]

Hello,

I experience an intermittent issue with my Atheros wifi card or the
OpenBSD driver  for it on 6.2.

What happens is that it seems to drop out of the network ocassionally.
I am sitting in the same room as the access point so it can't be a
signal problem.

I have found that bringing the interface down and them back up and
renewing the DHCP lease seems to solve the problem.

Also, OpenBSD does not seem to realize the problem is solved until I
test the link with a ping.

E.g even after the interface is toggled on/off and the lease is
renewed firefox will still be waiting for a page to load until I ping.

That seems strange.

I wonder if it is a hardware / thermal problem with the card. The area
the card is in in my machine is pretty hot.

This is a pretty minor issue and I could try another wifi card sometime...

I am just wondering if anyone has any insight into other possible causes.

Thanks.

Firefox does not start (at least without significant lag) sometimes after crashing

[Z Ero]

6.2 AMD64, firefox 58.

If firefox crashes (which happens rarely) sometimes I find it does not
start back up again. It seems to become a zombie or something. It
starts then goes directly to suspend. Why? Any work around known?

I suspect it has something to do with dbus waiting for something or
firefox waiting for something from dbus.

I have found killing my multiple attempts at starting firefox
eventually produces a dialogue window saying "firefox is already
running but not responding." Well... Then when I kill the process that
started the dialogue window it firefox finally starts.

But this behaviour is strange and the solution would not be intuitive
to many less technical users (e.g. if one was using OpenBSD + Firefox
as a platform for a thinclient / web browser + think client based
application). Maybe firefox eventually starts on its own (after 5
minutes) but I have never had the patience to wait around to try
that...in any case that would be unacceptable for a general user.

Does any one else experience this?

Is there any solution / work around?

Thanks.

swapctl question

[Z Ero]

amd64, 6.2

I have my swap partition set to priority 9 in fstab.

Why does swapctl report priority 0?

# swapctl

/dev/sd0b 11874624  1266232 1060839211%0

14d16d0d42a89629.e /var ffs rw,softdep,nodev,nosuid 1 2

I want to minimize swapping since I am using a mechanical hard disk
and thus swap slows things down.

I can disable swap if I want with swapctl -d but I would rather not.

kernel (6.2 amd-64 mp) relinking failed on cloned disk

[Z Ero]

Hello

I cloned a disk that had OpenBSD installed via

dd if=/dev/r{source_dev} of=/dev/r{target_dev} bs=16m

Now when I boot from the cloned disk I get the following error
login: reorder_kernel: kernel relinking failed; see
/usr/share/compile/GENERIC.MP
/relink.log


When I cat "relink.log" I get
 (SHA256) /bsd: FAILED

Does this mean that a machine specific hash / checksum required to
validate / execute the kernel relink is not working or what?

Otherwise the machine works fine.

Is the error a real cause for concern? Cloning a working setup with dd
as I did saves me a bunch of time vs. installing and configuring a new
system.

Also, how to correct the error, if possible?

Thanks

Re: Why are so many people running and writing about current snapshots

[Z Ero]

I just don't want OpenBSD to turn into Linux where the fixation is on
newest shiny thing rather than doing code right. Sometimes I think
people who are excessively interested in bleeding edge features more
want an OS for tinkering with than an OS for production / work. I want
something stable to use. But to each his own.

Is 6.3 release almost here? Is that why? If you are using your

OpenBSD why would you run a current snapshot rather than the stable

How do I disable specific keys on Thinkpad laptop?

[Z Ero]

Hello,

I want to disable / render dead in the software environment the web
navigation keys next to the arrow keys. Multiple times I have gone to
press the up or down arrow keys while filling out forms in Firefox and
accidentally hit the "back" key. If I have typed up a 500 word forum
post it is lost irretrievably. I don't want these keys to function any
more in X11 but I would rather not mutilate my keyboard to make that
happen. I suppose I could research it but I want to go back to
retyping my post and am hoping some kind individual can point me in
the right direction to speed the process of the solving this problem
along...

Thanks a lot!

Minor user space issues

[Z Ero]

Hello,

Two quick questions that may be basic but I never learned to solve yet
since they are not necessary for my work. Solving them would just make
my user experience a little better.

1. Is there a way to eliminate core dumps from crashed applications. I
don't want firefox to make a 1 GB core dump in my home directory if it
crashes.

2. Is there a way to supress or redirect console messages &
application error messages so they do not clutter my xterm. For
example I would rather

cat console.txt

than see a message on my xterm every time I plug in a USB device, etc.
Also I don't care about seeing every single little GTK error or
warning firefox has. In fact I would like to see none of them on my
xterm but would not necessarily mind storing them in a log file or
/dev/null.

Re: Lenovo X61 (notebook not tablet) does not return from sleep

If the adapter is ejected before closing the laptop lid there is no
problem waking from sleep. But is a minor inconvenience to eject the
adapter. Would it be possible to patch the kernel some how to make it
think the adapter is ejected before entering sleep?

Fwd: Is Absolute Software's Computrace AKA Lojack for Laptops a problem?

For OpenBSD users on second hand Thinkpads does computrace present a
security concern? I understand that the phone home agent runs on
windows but is there anything is the "predesktop environment" that can
pose a security threat to OpenBSD users related to computrace? Thanks.

Webserver Meltdown Patch Importance?

[Z Ero]

I have a web facing server running nginx, php5-fpm and mysql /
mariadb, It is still on 6.1. Remarkably I have a continuous uptime
without incident of 150+ days. I understand the meltdown patch is
available for 6.2. From a security standpoint how urgent is it that I
upgrade and apply the patch?

Notably the webserver is a VPS not on bare metal. If my VPS provider
is not patched against meltdown what difference would it make?

Are virtual CPUs even susceptible to meltdown? I suspect not. But the
underlying physical CPU would be.

drm permissions error with i965 on amd64 6.2 with libGL applications

[Z Ero]

"libGL error: failed to open drm device: Permission denied
libGL error: failed to load driver: i965"

I can solve it by changing the permissions on /dev/drm0 to rw for users but:

(1) I am not sure if that introduces a realistic security risk.
(2) The permissions are reverted on reboot making a minor annoyance to
reset them.

Advice?

Re: iwi0: fatal firmware error

[Z Ero]

I believe these era Thinkpads will not accept a non-IBM authorized
minipci WIFI card without Bios modification.

See http://www.thinkwiki.org/wiki/Problem_with_unauthorized_MiniPCI_network_card

If your bios accepts an IBM part numbered Atheros card I would
recommend that as the Ath cards have excellent support on OpenBSD
and have good reception characteristics.

If not either you have to live with the error, hack around it, or get
an external / usb wifi adapter.

Not showing in pip3 --list after installed with pkg_add. Not available
module. Why?

ReText Python Based Mardown Composer on OpenBSD

[Z Ero]

Does anyone have experience running ReText on OpenBSD? Anything to
watch out for when installing or any tips?

Generally Python packages work well on OpenBSD. I am having some
trouble with this one in terms of missing module(s) / etc.

On a slightly other note I attempted to build Qt5 from ports/x11/qt5
and that did not work. What is the best way to get a working version
of qmake(5)?

I need qmake to build a python-qt dependency that ReText apparently
requires to show live previews (the whole point in running ReText to
start).

Maybe there is another way to install the missing dependency.

ReText is Python3 based. My system is primarily using Python2 modules.
It seems that Python3 did not recognize the Py3-Qt5 module required.

Any help would be greatly appreciated.

I don't know if it is only me but building large complicated ports
like Qt always seems to be living hell / very little reward for the
work.

Thanks.
