debdrup, I am sure that most people don't want hard real time systems. Because if so then that's what we would have. We don't so they don't.

For doing bulk calculations normal timesharing systems is better. And most of what we do is bulk computing.

Hi, I was looking at a FreeBSD 14.0 machine on a 10GbE network, but iperf -s tells me that FreeBSD is only allowing approximately 6 Gigabits/second instead of something closer to 9.4 Gigabits/second that I see on Linux, FreeBSD configuration changes don't appear to improve the bandwidth available, is it possible it is just due to poor performance in the FreeBSD source code? i.e., does anyone have FreeBSD running with 10GbE and decent b

andwidth in a iperf -s test?

I have a question about wifi, and I got a feeling a network manager will be required for this, but I will ask anyways... I have wifi enabled using DHCP and WPA parameters... however IPv6 is manually configured on my network... is there anyway to match an SSID with a DHCP allocated IPv4 and a static IPv6? without a network manager?

to be honest come to think about it, this is something which is easily scriptable

although I feel that would just be reinventing the role of a network manager...

yeah, let's not do that

i feel like the proper solution is to fix the ivp6 network

ya let's get ipv6 polished

either dhcp or auto addressing

rtprio: no can do currently :P

polarian: if it helps, we're getting a DHCPv6 client "soon" which means you can configure static IPv6 addresses there like you would for DHCPv4, so no need for static config

I think I should just write a script...

it seems my emails to freebsd mailing list have went ignored however... maybe I should ifdown wlan0 in the meantime

Maybe I'm not understanding the issue, but it seems like static v6 and a DHCP acquired v4 would be pretty standard? What's the problem?

Title: Wifi/Bluetooth hardware switch on Dell E6430

seems like a script you could write into DHCLIENT-SCRIPT(8)

ek: well I can switch wifi network, I want the IPv6 statically assigned to wlan0 ONLY when connecting to a specific SSID

rtprio: I assume I can just parse the ifconfig output within the script to check if the SSID matches, and then set the address?

polarian: Ah. I see. It sounds like the switch on the Dell is software driven and not hardware driven (so, that's a bummer.)

yeah, or chcek it with wpa_cli

Yeah. I would think you could just set up the WPA config to use a static v6 address when connecting to any particular SSID.

ek: I believe I remember it working on void Linux... probably another GPL'd driver which BSD can't use

also wpa_supplicant supports static addresses within the config?

ek: i don't see a static option

neither do I in the man page

i'm rather surprised wpa_supplicant doesn't have a way to run a script when connecting to a new ssid, unless i'm missing it in the manpage

lw: its usually wrapped with something like NetworkManager on Linux... so I see why it doesn't :P

I think NetworkManager wraps it... it might implement the supplicant logic itself.. .

reddit.com/r/voidlinux/comments/rapmhh/comment/hnkn7pr <-- yep appears so

I will try rtprio's suggestion

Thanks for the advice

"WPA inet <ADDR> netmask <MASK> ssid <SSID>" doesn't work anymore?

Title: Solved - Static IP over WPA Wifi | The FreeBSD Forums

ek: you mean in the rc.conf?

not the wpa_supplicant.conf though?

Yes.

there is a downside to that...

if I connect to say my university wifi... which is IPv4 only

it will assign a non-routable IPv6 address...

it must only execute when its a specific SSID :)

I've not tested this, but if you specify the SSID in /etc/rc.conf, it should only use that configuration for that SSID. Multiple lines for the assignment of IP's might be supported for different SSID's.

Again, I cannot guarantee this. But, give it a shot and see?

oh wait I completely missed the ssid option

I will give your solution a shot first, and then go with rtprio if it doesn't work

thanks for the he;l[p

help*

Sure thing. Good luck! I hope it works. Would like to hear the outcome of the testing. If I had an FBSD laptop to test with now, I'd give it a go myself.

sure I will ping you if it works, if you are good with that?

likely need to try it tomorrow though, its currently 3am :P

ah, 3am, the Periodicing Hour

Periodicing Hour?

like the witching hour but more freebsd. (it's when periodic daily runs)

oh. i assumed you'd move this wireless device to other networks

but if not, sure, ek's idea is good

why do i get "lockf: /var/run/periodic.daily.lock: already locked" when i run sudo periodic daily?

polyex: it's already running, or perhaps it somehow exited and didn't clean up the lockfile

hm ya i'm getting periodic sitting around with locks hmm

on a few different jails, but 1 not

it was in 3 of 4 jails on a new install. rebooted, they were working. weird

i wonder if it's flakey

rebuilt machine and all jails were working

weird

14.1 inc

ek: are you sure that rc.conf line doesn't just restrict the interface to that one ssid? polarian want diffrent configs depending on ssid (static ipv6 for one specific ssid, else normal automatic dynamic ipv6)

i'm having an issue with network tuning, using 15.0/amd64 on two systems - on both sides i've set kern.ipc.maxsockbuf=614400000, net.inet.tcp.{send,recv}space=4194304, MTU is 9000, TCP hostcache is disabled. with iperf3, in one direction i get 9.88Gb/s with 9k byte packets, in the other direction i get 1.68Gb/s with 1500 byte packets. what's going on?

netstat -Wrn shows mtu 9000 as expected on both sides

the only difference i can see between the two systems is that during the slow test, the 'server' side is using a bridge rather than the physical interface

jbo: ping

trying to destroy a dataset. but it claims its being busy. is there a simple way of inspecting whats "using" it?

drobban: fuser -c mountpoint

nimaje: I am not sure...

may as well try it

and if it works then good

if not oh well

also USB speeds are painfully slow...

150kB/s is the max dd can write a usb stick... this USB stick can do much more...

I have heard this complaint a lot from FreeBSD users, is there any fix to it?

Title: dpaste/d7KFV (Python)

thats the dmesg

polarian, what block size do you use in the dd command?

V_PauAmma_V: default

Try 128K.

Or 1M as docs.freebsd.org/en/books/handbook/bsdinstall/#bsdinstall-usb says to.

Title: Chapter 2. Installing FreeBSD | FreeBSD Documentation Portal

freebsd++

development of freebsd still got directions i favor ^^

V_PauAmma_V: I will try that now

yup much faster with 1M bs

and conv=sync makes it even faster... I guess this was a case of RTFM

FreeBSD dd doesn't seem to have the same defaults as other platforms then?

llua: interesting thanks! did not know about fuser.

I found a segfault

if you specify inet6 with subnet in rc.conf and sh /etc/netstart

it segfaults

that's strange sync would make it faster

not slower

maybe it's because of the purely sequential workload

if you sync immediately it doesn't give the chance for controller reordering

big chunks

sounds painful

which command segfaults

d

lost the backlog since my last message, if anyone responded please resend

is there no way to add a route with ifconfig(8), route(8) must be used? because I can assign a static IPv6 through ifconfig arguments in rc.conf but not add the route for it

< rtprio> which command segfaults

sh /etc/netstart with inet mixed with subnet

inet6*

I accidentally did "inet6 <ipv6 address> subnet 64" instead of "inet6 <ipv6 address> prefixlen 64"

I just have just done CIDR but meh

the first (incorrect) one segfaults

Which command in /etc/netstart?

not sure... let me go break my laptop again then I guess

hm weird... its not segfaulting this time

nevermind then I guess

You can configure static routes through rc.conf arguments: see static_routes and ipv6_static_routes. (That feature uses route(8) indeed, but that's an implementation matter.)

V_PauAmma_V: ah thanks for the pointer :)
