Well no, because that would give results for all packages, not each of
them; no full path and extra garble.

I'd have to think of a shell script.

I don't see that behaviour on my carp pair. Are you using a cross-link
cable between the two firewalls? (You shouldn't, in my experience.)

Correction: "pkg_info -f" will also show me the packing list of remote
packages, so that is not an option either.

How do I get a list of the files of only installed packages?

[Ottavio Caruso]

Hi,

"pkg_info -L PACKAGE-NAME"

will give me a list of all the files within each package, regardless
of whether the package is installed or not.

How can I restrict the output to only installed packages, making it
fail if the package is not installed?

I could do:

"pkg_info -f PACKAGE-NAME "

but that would not give me full pathnames.

I've looked at the pkg_info man page but I couldn't find a clue.

Thanks.

Re: Potential awk bug?

Hi Philip,

Thanks for the quick response. I certainly wasn't expecting to find an 
ancient bug like this. Should I be reporting this bug upstream, or are 
you planning on upstreaming a diff?

I have no idea about what is going on, but FWIW I can reproduce
this on
i386 6.7-stable and amd64 6.7-current (well, current-ish, #232).
Truncating the file to a single offending line produces the same
result:
log($5) is out of range.

It appears to have something to do with the last field. Removing it or
changing some of its characters seems to work, e.g.:


arin|US|ipv4|216.250.144.0|4096|20050503|allocated|5e58386636aa775c2106140445cf2c30

arin|US|ipv4|216.250.144.0|4096|20050503|allocated|5a58386636aa775c2106140445cf2c30
                                                    ^
Fails on the first line but works on the second.


Hah!  Nice observation!

The last field of the first line looks kinda like a number in 
scientific notation, but when awk internally tries to set up the 
fields it generates an ERANGE error...and the global errno variable is 
left with that value.  Several builtins in awk, including log(), 
perform operations and then check whether errno is set to EDOM or 
ERANGE but fail to clear errno beforehand.


The fix is to zero errno before all the code sequences that use the 
errcheck() function, ala:

pfsync interface in carp group

[Paul B. Henson]

I've had a pair of redundant firewalls using pfsync for years. I've 
noticed in the past that whenever I rebooted the secondary firewall, the 
carp interfaces on the primary would flip to backup and then back to 
master as the secondary one rebooted. I never really noticed any issues 
with it, so I just ignored it.


Since upgrading to 6.7 though, if I have an active ssh connection to the 
carp IP address on the primary when I reboot the secondary and these 
interface flip-flops occur, my connection is dropped, which is undesirable.


It looks like this is happening because by default the pfsync interface 
is in the carp group, so when it goes down, it demotes all of the carp 
interfaces on the system. I can see why this would be useful for a setup 
using multicast and more than two firewalls, as if you are not 
synchronizing states, you are probably not the best choice to be the 
active owner of the virtual IP addresses.


However, for only two firewalls, when you're using the syncpeer 
directive for the pfsync interface, it seems it would be better not to 
default to belonging to the carp group? With only two firewalls, if one 
of them has broken synchronization, so does the other, so is there any 
real point in trying to migrate away from the one that's currently master?


I updated my configuration to remove the pfsync interface from the carp 
group and now when I reboot there are no issues with the carp interfaces 
changing state or connections being dropped. Would it make sense to not 
automatically include the pfsync interface in the carp group if it is 
using the syncpeer directive?


Thanks…

Ah, I think I seen that in the past but did not remember it offhand. 
Thanks; although these boxes run OSPF and the default route changes 
depend on the network state, so I'm not sure that this would work.

I thought about doing that, but I ended up just making a table with a 
single IP address in it, each router having the appropriate IP address 
in the table, and the rule referencing the table being exactly the same 
on both. Everything is working properly now.


I do still wonder if this requirement is documented anywhere? I've been 
looking, and could not find it. It was very confusing trying to sort out 
why my states were mysteriously disappearing, I ended up having to add 
some extra debugging code in the kernel to figure out what was happening.

usb keyboard suspend and hibernate problem

[Switch 1024]

Hi,

I have a Ultimate Hacking Keyboard [1] and it seems to prevent my
lenovo X1 Carbon 4th gen. from suspending and hibernating.

Sometimes it works, but more often than not, the power led flashes
rapidly, the displays turn off, hdmi cuts out, the fan starts up and
thats it.

after quite some time i found that I can make the machine reliable
suspend if I disconnect the usb keyboard before executing zzz.

I am wondering if there is a command with which I can poweroff the
keyboard in /etc/apm/suspend?

Thank you,

best regards
Rai

OpenBSD 6.6/amd64 kernel crash: softdep_deallocate_dependencies: unrecovered I/O error

[Antonius Bekasi]

Hi Misc,



This is just a report. My lovely OpenBSD firewall crashed lately too much. So 
here kernel debugger output.

I was using softdep in every partition. Now i removed every softdep from fstab. 
I think using softdep under /usr partition was the source of my fault:

Ok, Thank you, I downloaded the sources for x-on-resize [1], got it to
compile with clang, but I do not receive events.

Clang line:
clang -v -L/usr/X11R6/lib/ -lX11 -lXrandr
-I/usr/src/lib/libX11/include/ -I/usr/src/proto/xorgproto/include/
-I/usr/src/lib/libXrandr/include/ -I/usr/src/lib/libXrender/include/
x-on-resize.c

I modified the source a bit to get some output:

```
for (;;) {
int configed = 0;
int resized = 0;
printf ("in for\n");

do {
printf ("in while\n");
printf ("XNextEvent\n");
XNextEvent(dpy, );
printf ("ev.type: %d\n", ev.type);
switch (ev.type - event_base) {
case RRNotify:
printf ("in RRNotify\n");
nev = (XRRNotifyEvent *) 
```

But I only get "in while", then "XNextEvent" and nothing more, it sits
there. If i execute Xrandr, change Xrandr configuration, disconnect
HDMI port, reconnect HDMI port, I do not receive any events.

Does any one have any thoughts? Could it be my graphics card?

This is a clear sign of hardware failing.

We are not up to date but upstream (https://github.com/onetrueawk/awk)

Re: OpenSMTP relaying to multiple mail servers

[Robert Sacks]

On 6/7/20 12:42 AM, Predrag Punosevac wrote:

I have a very noob question. Is it possible to configure OpenSMTP to use
multiple relay servers?


Yes. I would create an action for each relay like this:

action "gmail" relay host smtps://gm...@smtp.gmail.com auth 
action "outlook" relay host smtps://outl...@smtp-mail.outlook.com \
auth 

and then create a match rule for each email address like this:

match mail-from "someb...@gmail.com" for any action "gmail"
match mail-from "someb...@hotmail.com" for any action "outlook"

If you want to use more than one email address for a relay you could 
also use `match-from "@gmail.com"` or use a list table.


You can read this blog post[1] for a more detailed explanation.

Have you considered that it might not be the ISP's problem?
OpenBSD's pppoe(4) is not perfect.

One suggestion would be to, just like on Linux, run jobs that need to
run at least once a day (if the machine is up at least once a day) using
anacron.  The anacron tool is available as a package.

You would trigger anacron with a "@reboot", and possibly also with a
"@daily" cron job.

Getting HDMI Events

[Switch 1024]

Hello again,

tldr; My question is, how can I get  HDMI Events, I want to execute scripts
when a new HDMI (or DP, for that matter) device is connected or disconnected.
Maybe there is a really obvious or simple way or solution but I did not see it.


Reading the man page for kqueue, I was very excited to see that I can
monitor for HDMI changes EVFILT_DEVICE and NOTE_CHANGE.

But I do not see how I could use it, I am not sure what would be the
descriptor to watch for in this case. Also the perl kqueue cpan module
does not contain the EVFILT_DEVICE stuff.

I tried anyway using values defined in the .h files, tried to use
various outputs like pci device number etc. as a descriptor but it did
not work.

Using incron does also not work as it only concentrates on
files.

I checked the hotplugd but did not get anywhere either.

Then reading the source of drm etc. and I see that at least HDMI
changes do send NOTE_CHANGE events to kqueue, so they should be there.

Using xev with the -event randr should print randr events, and I
thought HDMI connects or disconnects should be events randr talks
about, but it does not work.


I am very interested in this because I created a set of scripts which
check the EDID output and stuff and create a hash and based on that
executes defined scripts so in my home, the monitor is left of the
laptop, but in the office, it is actually right of the laptop for
reasons. And when I am on the road it just turns off the other
outputs, but now I have to I3 bindsym a key binding to execute it when
I come home from work and connect the monitor.




Thank you

cron scheduling on a laptop and backups

[Switch 1024]

Hello,

first time OpenBSD user here. I came from 20 years of linux, then 6
years of freebsd, and finally arrived at OpenBSD, thank you guys for
doing such a great job. It just feels right, feels like home!

While checking about how to backup the system correctly, and what
files I need to recover my system and checked the altroot strategy,
which is executed from the daily script which is started via cron.

I checked my cron log and there are no executions of daily, weekly,
etc. I only see newsyslog jobs being executed. Right, I put my laptop
to sleep or turn it off most of the time when I am done working.

So how to deal with this correctly? Change the hours to run the
backups during the day? Is there a way to tell cron to run jobs it
missed? (Reading the man pages, I did not see that there would be ...)

How do you guys schedule these tasks (also cleanup tasks to clean out
/tmp etc. on your laptops?

Thank you,
Best regards
Rai
