Is anybody working on a Home Assistant port?

(Or are there major gotchas which would prevent it from working?)

what is it

saltd: home automation system, for central management of smart devices. Check home-assistant.io for details.

Title: Home Assistant

i see

well, here in russia it is not usable

anybody know if there is a way to get lftp to put xfers per line per parallel xfer instead of cycling through the xfers on one status line?

been trying to hunt this down and i'm coming up empty. starting to think it isn't even possible.

Speaker is very good.

debdrup do you like spray in L1 cache?

What.

meka: re. network mixers at your presentation, I can't help but wonder if SFP+ NICs isn't preferable as it has much lower latency and jitter than RJ45

Sorry to hear about your special reviewer :(

out of an exported zroot pool - where do I find stuff like /boot.config /boot/* and some other from / ?

I imported it at another system with zpool import -R /mnt, but do not see any of /mnt/boot.config /boot/*, /etc, .... etc.

ahh, this seems to be making that trick:

$ sudo zpool history zroot | grep noauto

2022-06-12.13:01:22 zfs set canmount=noauto zroot/ROOT/default

so with nfs, can you map a home drive?

What's the rule of thumb these days for swap size?

_xor: that's a good question

What I heard is: twice RAM up to... I think 2GB RAM but don't take my word for it, same size as RAM beyond that.

i heard twice the ram size myself, at least

From what I'm reading thus far, these days it's generally advisable to go conservative on swap with a 4gb-8gb upper limit (assuming 8gb+ phy mem).

i don't have a swap partition

That dates back to 1990s SunOS4, and IIRC isn't applicable to FreeBSD (or no longer) in that version.

tradar, then you can't troubleshoot kernel panics or crashes.

Enough for a mini-dump and optionally large enough to handle write speed when pages require swapping, but just enough runway to where OOM issues can be precluded within the write speed of the drive (before it fills up swap).

Hmm

I'm building my new system tomorrow. Got a M.2 drive and have 32GB of RAM. Going to run just FreeBSD on it, so trying to decide on a swap size.

_xor: i will be doing the same. i have an 80gb m.2 drive myself

Ah, here it is in the first paragraph of tuning(7): "The swap partition should typically be approximately 2x the size of main memory for systems with less than 4GB of RAM, or approximately equal to the size of main memory if you have more. Keep in mind future memory expansion when sizing the swap partition."

V_PauAmma_V: thanks for that

Right, but I'm reading opinions from sysdevs about how that's not really applicable these days anymore.

I mean it makes sense both ways. I'm trying to figure out the potential downsides (aside from space) of having a swap that's "too large".

:( :( :(

For instance, ZFS ARC (without tuning sysctl), by default will use up a large portion of available memory. Then it frees pages as processes request memory.

If the swap size is large, then I can imagine a scenario where ARC doesn't release pages since the system sees a large amount of memory (phy + large swap).

That's a contrived example, but the point is that I'm trying to come up with scenarios like that.

fuuuuuuuuuuuuuuuuuuuuuuuuuck

That's way beyond my ken.

?

saltd, would you quit that? It's annoying, as at least one long-time user already hinted.

_xor: i'm doing a nas myself qith 16GB ram

and got the 80gb m.2 ssd

what is zfs arc?

What? There are 1TB SDXC cards on Amazon for $20 each? Is there a device that'll let me attach a bunch of them to a computer JBOD style, so I can make a giant zvol?

A read-ahead cache, IIRC.

Or, geez, hard disks are even cheaper these days.

What is going on? Am I not in the 2000s anymore?

V_PauAmma_V: ahh, ok. that would be an interesting situation

14TB is expensive

so i do have a m.2 ssd that is 80gb and 16gb of ram. since i will be using zfs, what is a good recommendation for a swap size for basic pool of drives?

CCFL_Man give model of m.2 SSD

ghoti: the 1tb sd cards are not real

(at least, the ones for $20 arent)

another one.

saltd: you o k ?

I'm considering fcron or mcron for use on my laptop, one usecase being "run this command at that time or on the first boot following that, or restart it if interrupted". Anyone with experience with either (or another) can give me a rundown of pros and cons?

wanna i be fin e

V_PauAmma_V: I thought most people just use anacron? oh, that seems 20 years past maintenance

V_PauAmma_V: also, searching for mcron, the first thing i get is your prime minister

Prime minister, not president? :-)

ah what the heck to i know what he is, other than a menace

A meenace?

meena That, and it seems geared toward computers that are reliably powered on from 9am to 5pm or a similar mine schedule, which really won't be the case for my laptop if and when I have to stop leaving it on around the clock, because polyphasic sleep and irregular schedule.

s/mine/regular/ (WTF, fingers?)

which of them?

anacron

mcron, which is still maintained, has a white paper, from 2003: gnu.org/software/mcron/design.html

when installing freebsd in virtualbox, how can I scroll back/up in the console ?

when installing freebsd in virtualbox, how can I change the "resolution" of the console ?

hudo: I think the handbook mentions that

hudo, I don't think Virtualbox lets you enter scroll lock, but there's another key you can use. Scancode 104, which I think is pause? Hold on, lemme start a VM.

uuuh my laptop has no Pause key

You couldn't inject it into the VM anyway, but there's a Virtualbox that does that for you. HOld on.

Yep. From the VM's console window, Input > Keyboard > Soft keyboard.

V_PauAmma_V what do I have to do at Input>Preferences Keyboard ??

hudo, VIrtualBox has a menu bar which can be made static (but hidden out of the way) or turned off (then need to use some right-Ctrl key combination). On that menu bar is a item "Input" item

s/VIrtualBox/VirtualBox/ ; s/a item "Input" item/"Input" item/

On making the menu appear, see the response by "Steve Saporta": askubuntu.com/questions/59103/why-h…-virtualboxs-menu-disappeared#59105

Title: Why has VirtualBox's menu disappeared? - Ask Ubuntu

parv, yes I see the bar with Input > Keyboard then there is a menue "Preferences Keyboard" another menue "Display Keyboard" and some points like "Print Screen" or Insert CTRL-Break

so how can I scroll back in the console ?

hudo On the "Soft Keyboard" I see "Scroll Lock" button & "Page Up" (do not know if that would work with "vt" if that is what you are using instead of "sc")

it does

but i'm also wondering if vbox really does not pass scroll-lock through if it has the focus (vmware ws does), and it's usually fn+something on laptop keyboards

(on my lenovo it's fn+C)

V_PauAmma_V , parv, thx I got it ...

is there a good systematic way of examining which dependencies are introduced by a make option for a port?

jmnbtslsQE: `pkg info -d category/package`?

Title: PkgPrimer - FreeBSD Wiki

well, that's the dependencies for a built package

want to know for a port which options are associated with which dependencies

i'm trying to build emulators/qemu without all the X11 dependencies, not sure if it's possible / if one of the options is requiring those dependencies

i guess it might be the 'JPEG' or 'PNG' make options..these are supposed to be for VNC compression but maybe they somehow require X11 etc.

forums.freebsd.org/threads/ports-dependencies.84512/page-2 had some useful info on the first post - make -V LIB_DEPENDS shows some info

Title: Ports dependencies | Page 2 | The FreeBSD Forums

looks like it is mesa-libs being required by the 'OpenGL' option, i guess i should have guessed that

hmm, also cairo

it looks like the dependencies may be unavoidable
