I want to enable a swap file after intsalling FreeBSD 14 on AWS. I have dd'ed a 2 GB file from /dev/zero and run `swapon /swap.img`, but it complains that it needs a block device.

I have added swapfile="/swap.img" in /etc/rc.conf

Huh. That swapfile statement in rc.conf seems to have disappeared between ver 13 and 14.

Um. No. After FreeBSD 9.

Okay, I'm a bit behind, it seems.

Okay, a magic md99 line in fstab made it work.

What is that?

Sorry, found the information in the fstab manual.

Thank you guys!

greetings and salutations fine people of Libera Chat \o

dvl, Change is always disruptive. I am rather used to using zgrep because every system requires it. Fortunately I can continue to use zgrep even if not encrypted.

dvl, Why type in bzgrep? That's one extra letter that is not needed. And using it limits the file type needlessly to bz2 files only. zgrep is the same script by the way.

kdehl, I am just going to apply a caution that using a swap file on a zfs file system can deadlock. schmidp.com/2014/01/05/freebsd-10-does-swap-work-on-a-zvol openzfs/zfs #7734 bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1847628

Remilia, UEFI has been such a road of thorns that this just feels like yet another thorn in our tires.

Will mv command rollback is destination doesnot have enough space? I moved 62 gigs of tar file but running out of space, the file is back to where is was, is it safe to assume the file is still valid? Too big to extract and verify so better to confirm a little bit...

I mean if the destination doesn't have enough space...

that sucks not having the space

yeah... after about 20 minutes it errored with not enough space... forgot to check first, just want to make sure the file is still valid cause it's backup file, kinda crucial..

for sure

budlight: Thanks for confirming... I'm relived...

budlight is the same person as richard_

richard_ is on freebsd

in vm

hahah

my main os is debian

reading the bsd handbook

how do i fix sddm and dbus from scrolling down my boot screen i take it out of rc.conf but something keeps putting it back

first time i reboot i forgot to put sysrc infront

cannot help, startx here...

i have that too but i like it to go to the login screen

have you tried others like slim?

no

kde is the only desktop i use

KDE is a Desktop Environment. SDDM, lightdm, slim, xdm are X Display Managers. Meaning that they are separate components from each other.

xdm is rad

xdm is the grandfather of all of the graphical login managers.

i have try others

I think slim + KDE is also viable... so could give it a try see if it fix the problem

It's pretty plain by today's design standards and so lightdm and slim are the two most popular ones now.

I mma go back and copy that 62 gigs again...

Kinda scared, next time I'll stick with cp instead of mv...

I don't use sddm, KDE's replacement for kdm, but I debbugged through setting the locale with it recently to help someone and discovered that it was not simple. Made me unhappy because it propagates the idea that free software operating system desktops are trouble.

opr, Reading about your mv issue... If the source and destination are on the same dataset/partition/slice then the move will simply move the file and no data copy will happen.

If the move is across datasets/partitions then it will need to copy the file first and then remove the file from the source afterward. If the internal copy reports an error, such as out of space, then it will abort the copy and not do the second part.

But if it is across datasets then I suggest using rsync -a or rsync -t to copy the file first. Especially with 62GB. Then if that works then you can remove the source yourself. Since you know it is a copy then.

what ever got move be mv is lost ant it

by

For that size of a file I would use rsync -aP to include --partial --progress too. So that interruptions will preserve the partial file and be able to resume from where it left off.

Also having --progress there will give some feedback about how long it is going to take. For a lot of files I sometimes like --info=progress2 better. It all depends.

rwp: OH, thanks for the detail, learned a lesson today. It's a system wide backup with rsnapshot, I tarred the whole backup folder than transfer it to my NAS, but selected the wrong disk with not enough space.

I should've automated the whole process with rsync...

Hmm... I probably would have copied the files individually rather than tar'ing them up first.

I was following this blog post: subatomicsolutions.org/full-system-backup-and-restore

Title: Full System Backup and Restore

The old school way before rsync was «tar cf - | ssh remote tar xf -» type of thing. But that's not restartable in the case of a network glitch. It would need to do it all again. That's where rsync is better.

VimDiesel: haha You are on it.

rwp: I'll transfer to rsync methodology soon.

I haven't used rsnapshot myself before. There are a lot of backup programs out there. People keep creating new ones! These days I recommend "restic". It's a new kid rising star backup.

opr, Yes the bot VimDiesel is pretty useful to print out titles. But it does get confused if there are multiple URLs on a line and for some combinations of patterns. The failures of the bot are more fun than the successes, honestly.

:D

rwp: a tarpipe can be faster than rsync which is nice for an initial upload. You can resume after network failure with rsync

oh dang, my home is on /

I thought FreeBSD put home in /usr/home?

which O/S am I confused with

I guess I haven't used FreeBSD properly since 6 or 7

I *thought* /home was a symlink to /usr/home

so now I'm out of space on home

I guess I could always .....

Make it so

if i make a port can i turn it into a pkg somehow then keep it local and private and pkg install it by passing a path?

polyex: Poudriere docs show how to overlay local packageas.

packages*

polyex: If I am not mistaken, you can setup a pkg repository that is local for you, and as long as you put pkgs in there, you should be able to use pkg to install whatever is in there

anyone make their own tools and maintain a library of private packages?

zwr, Agreed that opening and closing a godzillian individual files can be a bottle neck for rsync'ing files. Or any kind of file copying. But rsync must stat(2) both files first and that can slow things down.

zwr, With one huge file the one single network stream can be a bottleneck. It can be faster to fracture the file into 100 parts and then transmit each part all in parallel. In a bandwidth sharing situation it will have more shares than a single stream.

People have done all kinds of things over the years to tweak and tune in order to get more speed.

does p;oudriere need root to run?

i can use a bhyve vm for a dedicated poud build machine for my network right?

polyex: sure

polyex: Also, there are not a lot of hits for it, but look at build_as_non_root in the config.

polyex: Also, note that there is #poudriere both on this network and on EFnet.

so poud can run without root?

Title: Code search results · GitHub

Yeah, it's sort of obscure, but there it is.

really cool ty

Hm, it's the default even.

according to that poudriere.conf.sample

what's cleanvar for? i see it in a rc REQUIRES

i read the script and i see it like cleans var shit but how do i decide if i want my rc to also REQUIRES it?

I have some question, such as: Can libnv be used on other non-BSD systems without Capsicum, and is there a documentation of the pack format of libnv? Also, can BSD be used with non-Unicode text, such as TRON character code? And, can a program work with some GNU functions (such as fopencookie)?

Also, where is the documentation of libuserangel? I could not find it?

the best way to work with non-Unicode text is to convert it to Unicode. And all the BSDs have plenty of GNU functions, yes. Sometimes you can use a library or implement them yourself if they're missing

I disagree. I want to support other encodings without needing to convert them, and supporting the possibility of character sets that may be larger than Unicode or have characters not present in Unicode, etc. I also want to be able to display text without converting it to Unicode (even if it is Unicode text; for security purposes sometimes it is better to display it as ASCII even if it isn't), etc

(Converting to/from Unicode always would be inefficient anyways, as well as inaccurate (although sometimes it is approximately good enough (as a fallback)).)

mason, polyex: no poudriere can't run as non-root itself, as it has to create jails, but it can and does build packages as non-root

Hey, I have problem with ethernet on 14.0-RELEASE, the status is active, I can get an IP with dhclient but still I cannot connect to anything

pinging an IP says that network is down, but em0 is UP and status: active

can you ping your router?

Yeah, I just noticed it is on 192.168.1.1 and not 192.168.0.1, so I was trying wrong IP to access it. However, another device connected through ethernet can access the web no problem

so I have access to the network but no access to the web, weird

bbrtj: netstat -4rn

also check /etc/resolv.conf

verify you have a default gateway

try `traceroute -n 8.8.8.8` or something

Remilia: thank you! I still had 192.168.0.1 in /etc/resolv.conf. Ran `sysrc defaultrouter="192.168.1.1"` and `service routing restart`, and now it works :)

hm, don't you use dhcp? pretty sure you get the default router from dhcp if you don't set defaultrouter in rc.conf

Seems like I'm not, will have to configure it

at least not automatically, as I got IP from dhclient

so you manually used dhclient to get an ip adress?

yeah

not sure if the rc script does additional stuf, but my guess would be that dhclient configures everything correctly if you remove that defaultrouter line and do a service netif restart to just restart everything (no idea what defaultrouter affects), but you can add DHCP into the ifconfig_* line so that the rc script automatically set everything up via dhcp

yes, I will try to set that dhcp in rc.conf later. I will also have to fix network access in jails, as it seems it stopped working. Stuff just broke with my new router

there any way to restrict a user to only running a specific 'service ...' command with sudo?

or is it only per binary?

I have some guy from alibaba trying to connect to my server 1000/sec, I am blocking his IP but pf keeps him in the state table

47.76.35.19:43321 CLOSED:SYN_SENT

I block him with block drop so there's no return

can I even block him from getting registered in the state table ? Eventually he grows to like 50 000 entries

hmm why does something that's drop even build up any state? seems like a drop should be stateless on the server

polyex: you can restict on a matching command string with sudo, which kinda works but is bad design, as you can easily match more than you wanted to allow, so you probably only want to allow exact commands there

hm you mean i can do what i'm asking but it doesn't work great because ppl can like rearrange cli args and get around it?

what would a sudo rule look like to allow not all of service, but only '/usr/sbin/service pf reload'?

looks like doas supports it

permit nopass bobthebuilder as root cmd apt args update

something like hacker10 ALL= (root) /usr/sbin/service pf reload

but that command section also allows wildcards, which for some reason match the command arguments as one string instead of list of strings and * matches space too, so just don't use wildcards in that command part

why ALL=(root) isn't ALL=(ALL) enough?

I just copied some example using the command part and replaced the used command with your command, look the exact syntax up and change it to your needs or change to doas if you want

"I block him with block drop so there's no return" And then he'll return after changing his IP.

nimaje: Thanks for the clarification. Building as non-root is the critical bit.

RhodiumToad: I remember you mentioning a while back that SIGABRT is often the result of X reason. Do you remember what X was? (or am I mistaken? There was a coredumped signal that I ran into a while back that I remember you saying is pretty uncommon, and I want to say it was SIGABRT.

assert() ?

Oh, that would make sense.

Checked the dump with lldb and it looks like it's calling a c++ stdlib method with invalid args.

_xor: uncaught C++ exceptions also caused SIGABRT

most confusing networking problem i've had for a while: pf by default doesn't pass packets with option headers, which includes most IGMP packets, unless you use 'pass ... allow-opts'

unixwitch: iiinteresting…

anyone know if Xorg in FreeBSD 14.0 works with intel iRIS Xe chipsets? When I add: kld_list="i915kms", freebsd locks up solid.. I have to remove that from rc.conf

I have drm-515-kmod-5.15.118_1 which should technically work with that chipset

meena: ask me how many hours i spent debugging why IGMP wasn't working because of this... :-/

unixwitch: how many hours have you spent debugging why IGMP wasn't working because of this?

that was a rhetorical imperative

hello. since i updated my bhyve vm to fedora 39, -s 30,xhci,tablet no longer works. the mouse doesn't work at all in the vm anymore

i need to remove -s 30,xhci,tablet from the bhyve command...then mouse works, but without tablet mode, it's not in sync (so it keeps going of screen when i move it around)

Interesting.

has anyone else ran into this and is there any work around?

Check back on 14.1 or 15.0 :D

as drm-kmod is a port whatever change is needed (likely) don't need to wait for a new freebsd release, but it seems like nobody knows what is needed to be done currently (well, maybe it needs changes to the kernel, but even that most likely works as a -p release and doesn't need to wait for 14.1 or 15.0)
