any suggestions for ways to turn "fd12:8247:3:1::1" into "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.0.0.3.0.0.0.7.4.2.8.2.1.d.f.ip6.arpa" in a shell script? preferably without doing an actual lookup

lw: echo it into rev, and then =mumble= to convert the :: to the appropriate number of zeroes.

mason: i just write a C++ utility to do it, that seems easier :-)

i was hoping one already existed but i can't find it if so

lw: No one would yell if you did it with awk.

lw: awk -F: '{ }'

haha yes

That said, I'm not wizardly enough with awk to know how to do it without a bunch of poking.

i doubt an awk version of this would be very nice

But either way, yeah, a real language seems idea.

ideal*

(C++ version: le-fay.org/tmp/30d/rdns.cc)

lw: Where's that handling the :: ?

mason: it doesn't need to handle the ::, it uses getaddrinfo() to parse the string into a binary address

kk

echo ${ipv6} | rev | sed -e s/::/00000000/ -e s/://g -e 's/./&./g' -e 's/.*/&.ip6.arpa/'

untested because I don't have a shell handy

kona: i guess the question was not clear, it needs to handle any IPv6 address, not just the particular one in the question

% echo ::1 | rev | sed -e s/::/00000000/ -e s/://g -e 's/./&./g' -e 's/.*/&.ip6.arpa/'

1.0.0.0.0.0.0.0.0..ip6.arpa

you could do it in a sed script but i would probably use awk and implement each address form separately

i was hoping for an existing utility to do this really, i prefer my C++ version over an awk mess (although i like awk and i'm using it elsewhere in this script)

kona, use perl, 3 lines as shown here: stackoverflow.com/questions/4800691…perl-ipv6-address-expansion-parsing

Title: Perl IPv6 address expansion/parsing - Stack Overflow

well, that's not exact. would be fairly simple to change it. looks like Net::IP is a good match.

is there no rc.d script to add static arp entries? i see $static_arp_pairs in rc.conf but i need to add one with the 'pub' flag

ok, actually arp 'pub' seems to be broken anyway...

# arp -s 185.73.44.139 02:00:00:00:40:15 pub

arp: delete: cannot locate 185.73.44.139

i didn't ask it to delete an arp entry (that would be -S) and it doesn't add the entry

lw: you can make a script which uses command arp -f <filename>, see man arp for the format of a file

further, arp uses lookup functions which lead (depending on configuration, see nsswitch.conf) to /etc/hosts

i checked the source and i don't think this is related to /etc/hosts - it tries to find the ifindex with the given IP address on and gives this error if it's not found. the 'delete:' is a typo in the source

so it can't be used for proxy arp, which seems odd

submitted freebsd/freebsd-src #1214 for the typo but fixing the actual problem seems more difficult, i wonder if the kernel doesn't support this

Title: arp(8): fix a type in error message for -s/-S by llfw · Pull Request #1214 · freebsd/freebsd-src · GitHub

ok, the problem seems to be in sys/netinet/in.c:in_lltable_alloc() which requires a route before adding a new entry

I have an old hdd I want to get rid of. I had an (unencrypted) zpool on it. what is the freebsd way to overwrite it? installd gnu shred?

or just physically destroy the platter and be done?

yourfate: dd if=/dev/zero of=/dev/daX bs=1M ?

should it be overwritten with random data instead of zeros? :D

yourfate: doesn't matter as far as i'm aware, claims of recovering overwritten data from HDDs appear to be mostly theoretical. you can use /dev/urandom if you prefer though

ok, so i partly solved my arp problem by replacing the IPv4 route to the host with an interface route (instead of a host route IPv6 nexthop), now i can add the ARP entry using my patched /usr/sbin/arp, but the system doesn't respond to arp requests

now i also can't delete the arp entry, and the manpage syntax of 'arp -d <addr> pub' isn't accepted by the command, i guess that's another bug

hmm dd says i'm not permitted to write do /dev/da0, even tho I used `doas`

yourfate: try deleting the partitions and partition table with gpart first

there is no partition table, its a whole-disk zpool

a zpool has a partition table, it is a GPT partition table with 1 partition covering the entire disk

gpart can't see it

does it show up in gpart if you destroy the pool?

no, but after destorying the zpool the dd command works

the nice thing is, I connected the drive to an rpi, so I don't care if it runs for a day :P

pkubaj, hi! Maybe you know is graphics/blender build on ppc*?

What mailing list is for general questions?

polarian: questions@, unless you're running -stable or -current in which case stable@ or current@ might be more appropriate

lw: and where should I stick the query about the RF kill switch problem/

which you recommended a week or so ago

i can't remember anything from a week ago but questions@ seems like a reasonable place for random hardware questions

lw: thanks :)

VVD: AFAIR only on LE

pkubaj, maybe add to NOT_FOR_ARCHS=

- L- 1/5359: Polarian Best way to run command on system start

polarian: you could just put it in /etc/rc.local

not really a great solution but...

hmmm

might work

if it works, its a solution :)

it's basically the same as "using a rc service" you just don't have to write an rc service for it because rc.local already exists

rc.local doesn't exist on my system :P

you must create it!

I know, I was kidding :)

it must be a shell script! so #! /bin/sh followed by the commands

you said "already exists"

of course i mean it philosophically exists

philosophical rc scripts are the best type of rc script

(who will defend rc.d-realism?)

hello!

I'm thinking of doing a master's in cyber security (for no reason other than I'm kind of bored), and for my dissertation I'm thinking of doing research on the topic of process injection in BSD-based systems (so ie freebsd, openbsd, netbsd)

I got this idea when writing custom implants for the BSD implants we have for a training course we have at work, googling around, and realizing there's really not much published research on process injection for BSDs

David Buchanan wrote an injector for linux that does not use ptrace and uses the /proc/pid/mem interface instead, do you happen to know if there's a facility similar to this in any of the BSDs?

(can be found here: github.com/DavidBuchanan314/dlinject )

Title: GitHub - DavidBuchanan314/dlinject: Inject a shared library (i.e. arbitrary code) into a live linux process, without ptrace

I know there's ptrace for BSDs, but that's boring and I was wondering whether this technique could theoretically be adapted to work on BSDs as well

I'm kind of a newbie in this specific topic so bear with me. Mostly I'm trying to figure out whether my idea for this dissertation is stupid or not

i'm trying to build a port and a configuration menu came up to choose different compile options. i need to deselect an option, but "make clean" doesn't make the menu come up again

xx_ns: mem(4) maybe?

i'm not sure how you would get the address of a particular process's virtual memory that way though

thanks for the pointer, i'll have a look

meena: are we ok finally to commit cloudinit to /quarterly/ ? I'm just being careful. maintainer ok came through a couple weeks ago.

Title: 277662 – net/cloud-init: backport 23.4.1 from main to quarterly

(also, I just have to say, my first exposure to FreeBSD was via pfSense, which runs on the machines on our training course I mentioned, and... I've really enjoyed working with FreeBSD! A lot of things simply make sense)

xx_ns: you should try to talk with antranig , see antranigv.am/about/#contact he has done work in this area

my video driver switches from i915kms to llvmpipe after closing and opening the lid of my laptop. I set "hw.acpi.lid_switch_state=S3" which seems to work otherwise. Adding "hw.acpi.reset_video=1" stops it from waking up again... Does anyone know where I can get more info on this?

Hi. I'm using OPNSense and trying to get some custom-built packages by Poudriere (successfully built on another OPNSense "Builder" Host based on the correct Release & Ports Tree, then served over HTTPS by NGINX). Basically using a Custom Repository in /usr/local/etc/pkg/repos/custom.conf. I (finally) managed to sort out the SSL/TLS Verification which now works correctly. However, even after pinning the current version of the <pkg>

Package to OPNsense (pkg install -r OPNsense pkg && pkg annotate -A pkg repository OPNsense && pkg annotate --show pkg repository which shows it correctly pinned to OPNsense Repository), it still wants to do an upgrade of the Package from my Custom Repository, when I try to run pkg upgrade. What could be the reason ?

Need to add CONSERVATIVE_UPGRADE = true in /usr/local/etc/pkg.conf ?

It still wants to upgrade ... uhm :S

dch: i thought that was a given??

dch: aren't you a ports committer??

wow rude

After S3, dino eats almost 100% of CPU

cant figure out why, any clue?

hmmm maybe hardware acceleration is being broken, all gtk clients seem to be slower

meena: yep but its been stagnating a month, so I wanted to be sure before breaking everything ;-)

there some way to sniff an http request coming in on a certain port? i wanna see the exact request url

ngrep maybe

tcpdump also did it actually

assuming *http*

could also do nc -vkl 1337

grpc

ketas, what's 1337% of Pi?

hah i had to look that

it rounds to 42 :p

That's the ultimate question to Life, the Universe, and Everything.

1337% of pi was wtf to obtain 42 tho

attempting to netboot an ARMv7 board. The FreeBSD loader gets loaded and by u-boot but the loader give the following error: net0: cannot set rx. filters (status=3) and then reports ERROR: cannot open /boot/lua/loader.lua: no such file or directory any ideas?

anyone used fluent bit and opentelemetry output on freebsd? i set tls on and in fluent bit's log it errors tls unexpected EOF?

ketas, that's an amusing piece of numerology.

anyone using opentelemetry collector on freebsd?

Anyone tell me if 13.2 daemon has -r and -R?

er nm.. mans are online

anyone using fluent bit? i can't get the http or opentelemetry outputs to work

found this in a literal junk pile the other week, finally had time to set it up, bsd-hardware.info/?probe=92725f96b8

Title: HW probe of Protectli FW2B Desktop Computer #92725f96b8

what collectors are ppl using for observability agents on freebsd? fluent bit is trash

Does freebsd support something like linux's IPVLAN? (I think.) I'd like to use multiple network interfaces with the same mac address.

wait I don't thinkI thought this through, I need this on the proxmox, not the pfsense. Nevermind xP
