i have a few udev configs sitting around for fixing permissions on:
- raphnet usb adapters
- SDRs

sure am glad that udev is there to make sure nobody can see what my n64 controller is doing, not even myself

it's a pre-release feature that's still in testing, so it's not going to be prominently documented since it is intended for use by developers at the moment.

there are plenty of other obtuse hidden configuration things in linux to complain about, like fontconfig, or polkit.

want to mount this random flash drive you found in the parking lot? sure, no problem buddy. want to mount an encrypted volume? whoa there friend i'm going to need you to enter your account password (no, not the volume passphrase, you need your account password as well) to authorize that. want to change that behavior? simple, you merely need to write a supplementary authorization policy in javascript to automatically authorize this particular action code. why yes i did just tell you to go gently caress yourself.

you can use �gio mount -d� to mount encrypted volumes from the command line without entering the account password or requiring root privileges, I think. Not sure if it requires you to be in a specific group or if you�re in the console logged-in group though, but I expect that to be the case.

i did have a sennheiser headset where they updated the wifi dongle to be compatible with a switch, which broke windows/linux support. they of did released an updated driver. for windows

i had to touch udev and pulse audio then, and do some kernel bullshit because the usb device ids changed, but that was years ago and probably the last time i had to touch udev lol

iirc there are popular 2.5 GbE realtek USB dongles that perform like poo poo with the default generic cdc_ether driver (like ~0.5 Gbps) but acceptably with the native chipset-specific driver (like ~2.3 Gbps). the kernel developers' position is something like, the device supports multiple modes, therefore it's a policy decision (i.e. userspace problem) about selecting whether you want to replace the dumb slow lovely driver with the good performance driver

really? how?

i actually have gnome set up (and mostly not working because of udev) on iSH (though things based on gtk like xfce/mate do work), but i can't change the hostname because of two reasons really. for one, the hostname service won't start without udev. secondly, there aren't any real network interfaces, it's just a bare minimum bridge to your system's en0

like, ifconfig even fails like so

code:

ifconfig: /proc/net/dev: No such file or directory
ifconfig: ioctl 0x8912 failed: Not a tty

so i'd like to try this other method of changing hostnames, just to see if it would work. tbh i don't really care if it does, i'm just curious about this. it defaults to using its root account so i'd likely have permission to do whatever anyway

ah the gnome control panel doesn't run. oh well. maybe it works with xfce or something, i'll give it a try when i feel like loving with it

you have to use a local xvnc or xrdp, and, well, that's not ideal on ios because it suspends background processes, so you have to use a workaround and blah blah nobody cares

"hostname" means like a dozen different things on linux

there's what's in /etc/hostname, what's in /etc/hosts which can be a lotta stuff and often has a short and long (more qualified) name, what your local router's dhcp thinks you are, what dns thinks you are, all the shorter/not fully qualified versions of the last two...

heck, there's probably something in dbus too or something equally asinine

Sapozhnik: Jan 2, 2005; Nap Ghost

Hostname is a kernel thing. Why the kernel needs to know or care about machine host name I don't know but that's what people are usually referring to when they talk about a machine host name.

Anyway if you're using some dumb hobbyist Linux userland that doesn't include systemd then that's on you.

well, i mean what's reported to dhcp (and like i said, that's actually a bridge to ios's en0 in this case), what you get with `hostname`, dns, mdns, etc.

i set /etc/hostname to "ish-ipad.local" and everywhere i can think of to check still just says "localhost"

yeah like i said i'm not actually using this for anything, it's just an interesting project imo that i was having some fun playing around with. it's honestly pretty impressive as is, but a lot of poo poo doesn't work (which is understandable if you know how it works under the hood). you can check it out here if interested: https://github.com/ish-app/ish (the app is on the app store, or you can try the testflight dailies)

whenever ive changed hostname in a linux it changes it in all of those, I can override it with my router though for local connections or make sure it stays correct

no no, you're not getting it: it's an entirely emulated interface. there's no dhcp server, the dns resolver is also emulated, and dhclient doesn't work because there is no network device (meaning there's no corresponding interface either)

ShoulderDaemon posted:

neat idea, but there's no /proc/sys either. i don't know what it's doing for procfs because while it's actually populated (barely), the procfs service doesn't start because it can't grep /proc/filesystems (i guess i can look at the rc script to see if i can get it to start anyway, but i'm not sure it would make any difference)
