"Every subsystem is a private fiefdom, subject to the whims of each one of Linux’s 1,700+ maintainers, almost all of whom have a dog in this race. It’s herding cats"
There are three similes in that quote. When your considerations are that disorganized, you have not finished thinking everything through. Fiefdoms, dogs and cats ... oh my! That's on top of wild west and other trite, well worn and rather silly similes.
Make your argument without recourse to inflammatory terminology and similes and you slighten the risk of pissing people off.
Clarity is in the eye of the beholder or as someone once said: "You do you".
I like to use my enterprise number and a UUID (all in lower case, for legibility). Here's an example:
.1.3.6.1.4.1.33230.0d456e46-67e6-11ef-9c92-7b175b3ab1f1
Now you might say that the UUID is already globally unique or at least pretty unlikely to turn up anywhere else, so why bother prefixing it with more stuff? To that I say: "I need to be absolutely or at least reasonably sure ... OK nearly sure".
Anyway, you maintain a database of these things and then attach documentation and meaning to them. An editor could abstract and hide that away.
I started this post as a joke. Not sure anymore. Why get your knickers in a twist with naming conventions for variables and constants. Programming is already a whopping layer of abstraction from what the logic gates are up to, another one wont hurt!
If you just run perl it will sit waiting for input. Try perl --version
Windows GPOs are a right old mess. I've been managing them for over two decades. The first fuck up is the word "Group". You cannot assign Group Policy Objects to AD groups unless you use something like ZENworks or some funky WMI filters!
Settings are applied to computers or users. Many settings are available to be set for both but only make sense or even work for one or the other. MS bought out some solution providers and that's why you get the Control Panel and other handy stuff, rather roughly bolted on.
AD with GPOs with the extension to "local machines" is a great idea but dreadful in execution. MS didn't want to nobble third party apps in the past so that's why we have this nonsense. Now its all about Azure/whatevs ie MS's cloud and subscriptions.
Now you belong us!
Linux being a Unix has NIS(+) for a directory or LDAP or AD or anything else you fancy. Ansible works for all mainstream OSs, including Windows.
So often I see people confusing and conflating authentication and authorisation, machine and session state configuration databases.
There are so many options it is almost impossible to know where to start!
Which distro is the VM running (is it even Linux)?
If you want the VM to use the host's VPN then you will need some routing and perhaps NAT/masquerade. This is non trivial to sort out. Can the VM have its own VPN connection to your supplier?
You are starting to reach the point where VLANs/subnets and separate routers (real or VM) may be required. Depending what you use as your ISP router, we might be able to get a solution together - so what model is it and do you have any switches?
Lemmy is quite good at not being too "tribal". Why not embrace a message as expressed, instead of worrying about where it is ... posted?
For me, one of the worst issues affecting t'internets is tribalism. Us humans are hardwired to go all in on tribal affiliation. It is generally harder to find inclusive measures than it is to find exclusive measures.
If you are here then you may not be exclusively: Firefox user ⊆browser user ⊆human. Note that browser user can have multiple browsers.
IANAL but I do have a fair handle on consumer rights in the UK.
In the UK the price displayed is "an invitation to treat". There are other laws requiring the price stated being the price paid, ie it must include all taxes etc. Prices per unit seem to be an industry "lol" sorry "best" practice here, rather than legislated for - it is a bit randomly applied.
If you keep your wits about you, you can do real comparative shopping. For example: in Somerset, Somerset produced Brie is cheaper in Tesco than French Brie. I can't remember if French Cheddar is cheaper than Somerset Cheddar or even if it exists. Obviously, there is the brand thing too to consider.
Anyway, the "invitation to treat" is not a binding contract. It is only a form of introduction to one. You see the price and might think OK, I like that and take the item to the check out. If the item was miss priced the shop may try to amend it. If you pay for the item then you are considered to have accepted the invitation to treat, the bargain is made and related duties are discharged.
That's sort of the central doctrine behind how you flog stuff for money hereabouts. There are lots of fluffy consumer related legislation to try and ensure it is all fair but in my opinion, no one has bothered to teach us proles about how a sodding contract is formed. All that extra legislation would be no longer needed if everyone understood ... where they stand!
It doesn't help when you hear stories of firms required to honour ridiculous prices due to silly accidents. You do not get to buy a Dyson Funky Biscuit Crumb Sucker 1000 for 20p because you Sno Pake'd out a few decimal places or an employee answered a phone call mid reprice. You get the idea.
Invitation to treat (price tag): £10.99 for a bottle of wine (with a £9.49 Tesco card offer price writ large) Go to check out: £10.99 - 1.50 (but we get to suck on your data, sorry you get a discount via your Tesco brand loyalty card) Pay: £10.99 now and get a £1.50 rebate as a voucher that only works at Tesco, probably. The voucher will expire in three weeks time.
Here the contract was successfully formed. A good was transferred from Tesco to you for ... some money and you might be 1.50 better off too. All a bit murky. That's why we have consumer legislation and why you and I need to now what on earth it is and how it protects us.
Please do a little research before trying random stuff. After checking to see if you are actually using the iwlwifi module, why not find out a bit about whether the mentioned param. is available to you and what it does:
Am I using the module. If the output from this is blank, then no:
$ lsmod | grep iwlwifi
iwlwifi 622592 1 iwlmvm
cfg80211 1331200 3 iwlmvm,iwlwifi,mac80211
Also verify with lspci -k as above:
$ lspci -k | grep iwlwifi -A2 -B2

sysfs is a pseudo filesystem with lots of info in it. cat the files here:
$ ls -l /sys/module/iwlwifi/parameters/
... to see what your current values are set at. You can install sysfstools and run this for a neat report:
$ systool -vm iwlwifi
Module = "iwlwifi"
Attributes:
...
Parameters:
11n_disable = "0"
amsdu_size = "0"
bt_coex_active = "Y"
disable_11ac = "N"
disable_11ax = "N"
disable_11be = "N"
enable_ini = "16"
fw_restart = "Y"
led_mode = "0"
nvm_file = "(null)"
power_level = "0"
power_save = "N"
remove_when_gone = "N"
swcrypto = "0"
uapsd_disable = "3"
xfs has reflinks. That means you can copy huge wodges of data nearly for free on one filesystem. For backup systems this is a killer feature. Veeam rolling up incremental backups into the last full happens in seconds because pointers to blocks are juggled around rather than the data blocks themselves.
xfs has been around for a very, very long time. I use it for larger filesystems eg Nextcloud, Zoneminder and the like (and Veeam backup repos that are not object storage). I use ext4 by default.
pfSense boxes - zfs because the alternative is ufs.
RPi - OverlayFS (with ext4 and tmpfs) gets you a generally read only filesystem with changes held in RAM. Ideal for kiosks, appliances and keeping memory sticks alive.
Windows - NTFS, it works well and has streams and there aren't many other options (ReFS is a bit new but it does have reflinks)
That looks like a cherry picked starting point. Read the whole thread for the full context.
fwiw, I don't think anyone comes out looking particularly good. However, attempting to describe Frenck as infamous here and now is a bit rich. That minor disagreement all happened during the pandemic and I'm sure we have all passed a lot of water since then.
What on earth went wrong?
Arch is just as safe as any other distro, sometimes more so. Being a rolling jobbie, smaller bits tend to break at a time. If you want to live life on the edge then Gentoo is your man but even Gentoo is becoming pretty safe. You might lose your windowing system for a while but you still have links2 to get to a search engine.
