Can you configure a permanent IP address in the client configuration (hostname.if file) that is outside the range that DHCP allocates, but still on the same network? Allan

That's what I used to think too… remember using a phone like that (Motorola MicroTAC… micro compared to other phones of its era, nothing micro about it today). I seem to recall the Ericsson A1018S I was using around the turn of the century referred to the smaller (almost full SD-card-sized) SIM cards as U-SIMs. Then I had lone of a iSquareMobility Kite for a few months (which is a nice bit of kit BTW), and initially thought my SIM card (what I understand was a U-SIM, in the older parlance) would fit. *WRONG*. Apparently, that is now what they call a "full-size" SIM today. U-SIMs are now a little bigger than a MicroSD card… and now they've got this silly nano-SIM format which needs to sit in a tray that's *bigger* than the "full-size" SIM it replaced!

Cards listed with the right model could have older firmware which don't suppor the MBIM protocol natively, but instead the older MSM protocol. Or they have MBIM, but it is hidden from our driver. Thus you end up with umsm(4) support instead of umb(4). With umsm(4) you need to do ppp yourself, it is not a transparent network driver.

You're using the wrong tool for the job, use an address reservation bound to the client MAC on the DHCP server instead. Whether or not requesting an address client side works, at any time it could fail due to a change in leases allocated to other clients, or configuration changes at the server end. If a specific IP is needed, use reservations instead. PK

Hi Stuart, Aha.

But I didn't realise then that I might also need to increase the maxthread value. I'll change these and see if that helps. (Bound to!) I find the message to be a bit misleading though: "proc: table is full" Clearer might be something like: "kernel: thread table full: reached limit: kern.maxthread" Or similar. I.e. the who, the what and the why. Thanks for the tip! Cheers, Robb.
How to request a specific IP address from DHCP server
Hi, I can't manage to request a specific IP address from DHCP server. It is just a testing lab, the requiested IP address (.104) isn't used by any other client.

plugging head phones does not mute speaker
hi all, i have this embarrassing little problem: when i play music and plug in head phones, the built in speakers are not muted, even though mixerctl says so. the headphones do work correctly. i get this output whith the head phones plugged: inputs.dac-2:3=80,80 inputs.dac-0:1=80,80 record.adc-0:1_mute=off record.adc-0:1=124,124 record.adc-2:3_mute=off record.adc-2:3=124,124 record.adc-4:5_mute=off record.adc-4:5=124,124 inputs.mic=85,85 outputs.spkr_source=dac-2:3 outputs.spkr_mute=on outputs.spkr_eapd=on inputs.mic2=85,85 outputs.mic2_dir=input-vr80 outputs.hp_source=dac-0:1 outputs.hp_mute=off outputs.hp_boost=off outputs.hp_eapd=on record.adc-4:5_source=mic2 record.adc-2:3_source=mic2,mic record.adc-0:1_source=mic outputs.mic2_sense=unplugged outputs.hp_sense=plugged outputs.spkr_muters=hp outputs.master=80,80 outputs.master.mute=off outputs.master.slaves=dac-2:3,dac-0:1,spkr,hp record.volume=124,124 record.volume.mute=off record.volume.slaves=adc-0:1,adc-2:3,adc-4:5 record.enable=sysctl doing a `mixerctl -t outputs.spkr_mute` separately toggles the variable, but has no audible effect, the speaker stays active either way. `mixerctl -t outputs.master.mute` (or pressing the built in mute button) does work, but obviously mutes the speaker as well as the headphones. dmesg says: azalia0 at pci0 dev 31 function 3 "Intel 100 Series HD Audio" rev 0x21: msi azalia0: codecs: Realtek ALC236, Intel/0x2809, using Realtek ALC236 audio0 at azalia0 the machine is a lenovo ideapad 500S. the device used to work correctly with linux. i'm running 6.8 GENERIC.MP#277 amd64. did i misconfigure anything, or could this be a bug? thanks in advance for any hints. -- cheers, björn
Quick Q: proc: table is full ?

What causes "proc: table is full", or better asked, what limit might I be
hitting?

I have yet to see a high of more than ~2000.
Sysctl shows me these proc values:
> kern.maxproc=8192
> kern.nprocs=283
I am the only user on the machine (Xfce Desktop and too many browser
tabs). I am a member of "staff" so I think these limits apply:

Also, a related question ... that message shows up in the output of dmesg
and also gets logged to the messages file, but it isn't reported in my
Xconsole window. In there I see stuff like this:
> Console log for mjoelnir
> drm:pid64450:intel_pipe_update_start *ERROR* [drm] *ERROR* Potential atomic

But no corresponding proc table full messages. Is it not considered to be
important enough to also go to this console?
Thanks in advance!

An informational message be printed in the case of the permission already being facilitated? Obviously the return code 0 is correct. Alternatively, maybe when you add a group without an ID, a warning? Or perhaps a groupadd man page CAVEAT? Or I could just pay ultimate attention to the numbers, in the future?
