nobody was expecting linux users sucking eachothers cocks in the comment section
I was, and so was c/unixsocks
idk tf chown does, use sudo instead. im not going to read man chown either.
sudo su
# do shenanigans in the cli/tui. gui is for noobs
# nvim, ls, touch, stroke, tease, rm
So I'm not the best at this, but this is my best guess (I have no experience in sysadmin, as I've only ever been the sole user of my PC and prefer not to network anything).
Owner #1, smackyboi, has ownership of a file called smutgame.AppImage. This means they can choose who accesses smutgame, if it can execute, if it can be read or written by certain groups, etc.
Owner #2, luvurealgood, on the system via their own account (or networked computer in the case of server storage) can't change these settings unless smackyboi says they could, because they're the owner and can add luvurealgood to the admin group for the file if they want. Smackyboi suddenly writes, sudo chown luvurealgood smutgame.AppImage.
Now luvurealgood owns that file and can make every change they want to it, including removing smackyboi from accessing it, as they're no longer the owner. They can lock down the file and forbid it from being executed, etc etc. I believe anyone who is in the admin group of that file can do anything to it as well, except change it's ownership if its already owned.
This is just from pieces of info and my tiny experience in Windows sysadmin shenanigans. Someone swoop in and correct me if I got anything wrong.
sudo chown <username> <file>
chmod 700 <file>
Don’t see a problem ;) /s
sudo chown -R <user> /
Never have a permission issue again! Lmao
Me trying to uninstall edge
Edge is the best browser for downloading much better browsers lol
Best Chromium browser*
Edge is literally the first program I use on a fresh install.
You can install firefox via cli like powershell.
winget install Mozilla.Firefox
First command I run on any new Windows install
Windows moment
Not necessarily. Linux can have files that are r---r---r--- too
sudo chown -R 1000:1000 /* && sudo chmod -R 777 /*
alias iownyou='sudo chown -R 1000:1000 /* && sudo chmod -R 777 /*'
Now I've learned enough to know that I can easily learn what all that apparent gibberish does with the "man" command, but you have no idea how unbelievably unapproachable this makes Linux look to the uninitiated.
Is there a technical reason that Linux apps can't/don't just pop up an authenticator thing asking for more privileges like Windows apps can do? Why does nano just say that the file is unwriteable instead of letting me increase the privileges?
Linux apps follow simplicity principles. If you don't have permission to delete a file, why assume you may know the password of the user who has permission?
You can preface sudo to any command to execute it with root privileges, which would be similar to running as admin in windows.
Graphical apps do tend to ask for authentication if it makes sense. No userland apps should need more permissions than the current user's in order to run.
Small pedantic correction, but you can’t preface every command with sudo; only executables can be invoked with sudo as it can’t elevate your current shell. Naturally, the way to execute non-executables such as builtin routines as root is to just spawn into a root shell with sudo su.
The GUI apps do (depends on your DE). Terminal apps like nano are designed to work without fancy desktop stuff, like Polkit. Any sort of graphical text editor should prompt you for your password.
systemctl still asks for a password, though. Because it's systemd, and it's part of everything.
Some do. I'm sure it is possible with terminal programs. In KDE, you do get authenticator pop-ups.
Hmm I just tried editing some systemd service with Kate and it did actually give me an authenticator popup when I tried to save it
Although then the prompt expired and now it does nothing when I try to save it. Restarted Kate and now it works again...
I haven't tried that before
When I try to go into the sudoers.d folder tho it just says I can't, and the same thing happens when I try to open the sudoers file in Kate. If I try to copy and paste a systemd service in dolphin tho it just says I don't have permission and doesn't give a prompt.
lol if I open it with nano through sudo it says 'sudoers is meant to be read only'
If you're on windows this means you don't own the file. Go to properties security and take ownership.
The default windows configuration is aimed at old people who will call tech support when they fuck up their PC.
You can take ownership of pretty much the entire filesystem.
Windows is actually hugely customizable people just don't.
Glad to see another voice of sanity regarding Windows.
If you haven't learned by now, on Lemmy the only valid option for dealing with Windows configuration and basic Windows admin tasks is to yeet Windows and go to Linux.
Sometimes one wants to access a file without making changes though. Escalating privileges is the answer in this scenario and windows doesn't make that as easy,as it doesn't really want to you act as SYSTEM
100% true, and a great counterpoint.
Copium/denial
That's well beyond even power user (imo) and into the forensic analysis realm though, where you should probably be using dedicated tools. I'm pretty sure there are still ways around this, ways to back up and restore the ACLs, but I haven't ran into a need to not touch the modified timestamp in the decade or so I've been doing tech work professionally nor in the decade before as simply a young enthusiast. There's still ways around that timestamp too, and arguments to be made that adjusting the ACL is touching metadata rather than the file itself.
I do what I can to stay out of ACLs at my workplace.
Windows ACLs are far more complicated than they have any right to be, and file perms are generally far simpler on Linux.
I am Root!
My work laptop had a pop-up from an application that basically said "we couldn't restart last time, so you e got 15 minutes until we reboot your computer" with no way to cancel or prevent the reboot.
Me: the fuck you are
* proceeds to kill the service and process from admin command line*
Get fucked fortinet, I'll reboot when I'm gods damned ready
had a friend that was having problems with his PC and windows kept bitching about he didn't have permissions. he ripped out the harddrive with it still powered on and threw it off his balcony into the lake screaming, "I fucking own you!"
epic moment in my life to witness such an event.
I own you!
take ownership & full access of all resources
threat actor exploits a vulnerable application that is (1) running as you to (2) access resources it doesn't need: they commandeer your system
how did that happen?
🤔
One time Windows told me I needed admin privileges to edit s file. I had admin privileges.
