user1 in group apache and user2 in group apache. if user1 screws up something in /var/www/ and I have logging turned on I will know it was user1 that did something.

Peret Finctor

oh, users can be in groups. Groups are like tags for users...

Rinzwind

No, users are in at least 1 group. And groups are collections of users, not tags.

Peret Finctor

Yes, I seen how I am in group username : username

I guess when I create a user, I automatically create a group of the same name.

Rinzwind

yes that is to force your /home/$USER/ to your user and nobody else.

Peret Finctor

I guess that's because there isn't something like "null group" or "forbidden for everyone" group. This group would probably be handy for somebody who didn't figuried out how groups and everything else works.

Can you think of the case when I'd want to set something outside of my home directory to group username? I probably should avoid it, don't I?

If access to the file is allowed for my user, but not allowed for my group, will I get access or not?

If allowed for my group, but not allowed for my user?

Well, groups do feel like tags for me at this moment. Adding user to the group "apache" is like tagging him as "heCanWorkWithApache". It's simular, isn't it?

Huh, I didn't know you can let more than one user to work with your /var/www/, and even more, log everything they do. It's magic?

Is that like filesystem logging?

almost never used su, sudo was enough for me.

GeoMint

22:17

@Zacharee1 i don't like MEGA, i preffer mediafire

Zacharee1

@GeoMint So ads, slow downloads, confusing interface? OK :p

GeoMint

its 10GB free

i prefer dropbox, but i have only 2 GB

Peret Finctor

After hearing that "everything is a file in unix", I was like "huh, ok, you guys are weird but maybe it's really simplified your os". When I heard what "you can set permissions for every file", I was like "Huh, it's interesting, but I'm not paranoid this much."

And after tying up those two, it became somewhat amasing.

I need more use cases for file permissions.

Zacharee1

@GeoMint 50GB free on MEGA

GeoMint

@Zacharee1 i tried to download once with MEGA, took too much time to load

i quit

Zacharee1

22:23

It's New Zealand-based, but aren't you closer?

Fabby

@ParanoidPanda No need to provide a video... Anytghing you still need from my side???

GeoMint

i am in greece

idk

Zacharee1

I think you should try again. They did a bunch of updating and are now mega.nz instead of mega.co.nz

Peret Finctor

Maybe I should create a 100 of these questions on main site, I dunno.

Fabby

@James :-) I wanted to add some custom auto-comments to the AU server

I've got as far as forking and cloning...

user136984

22:24

@Fabby: No, I mean, I don't know what you experienced with it, but the OP has accepted my answer so even if it didn't work for some, it worked for him so I think that we can forget about it now. :)

Peret Finctor

au server, huh

user136984

Anyway, I'm on Warty Warthog now! :D

Fabby

@ParanoidPanda So I have to to nothing?

Peret Finctor

Warty Warthog, huh

Fabby

I'm extremely good at that! :D

Peret Finctor

22:25

Zealand, huh

GeoMint

Mailbox by Dropbox will shutting down Mailbox on February 26, 2016 :( www.mailboxapp.com

Peret Finctor

Spam, huh

GeoMint

idk

Peret Finctor

I'm sorry, two people shut up and three keep ignoring me, it's irritating

user136984

@Fabby: Well, I am curious as to what you exactly experienced so if you could provide a screencast that would be interesting... But no, I don't really need you to do anything... :)

user136984

22:28

@Fabby: Do you run Warty by the way? :)

Fabby

Well, I can't even throw a file from my desktop into the trashbin...

@ParanoidPanda Never have, probably never will!

user136984

Oh you should, it's great! :D

Fabby

Are you collecting all Ubuntu versions in separate VMs or so?

Peret Finctor

@Fabby Yes, totally worth it.

da Boss

@HeatherBrown yes, I love pi-hole.

Peret Finctor

22:30

pi-hole, huh

user136984

@Fabby: Well, I have collected more or less all the flavours of the current version (and one of the original latest Ubuntu LTS)... So now I'm working my way through all the LTSs... :D

da Boss

@PeretFinctor it is probably now what you think.

Peret Finctor

@daBoss think, huh

da Boss

pi-hole.net @PeretFinctor

Peret Finctor

haa... "Explain file permissions to me" isn't a good question for a main site, is it?

user136984

22:32

@Fabby: By the way, why does your icon keep disappearing completely?

Fabby

@PeretFinctor Meh...

user136984

Are you doing something special or is that a bug in the script?

Peret Finctor

But who knows, maybe it will bring this site another 200 google hits, whatever you guys gain from it.

Fabby

@ParanoidPanda It does? Cool!!!

:D

Please define "dissapearing"

user136984

Well, your icon that says up to how far you have read just disappeared for a short while even though you were still here and then it just reappeared again, like you had left and then rejoined chat...

user136984

22:36

And I've seen it happen with mine too today...

GeoMint

gn

user136984

So I've filled a report.

user136984

@GeoMint: Oh, does that mean "goodnight"? :D

user136984

@GeoMint: Well, if it does, goodnight! :)

Thomas W.

@fossfreedom so we're on "red alert" mode with flags monitoring are we? :p

@ParanoidPanda gamer / AIM slang abbreviation for good night

though many people cringe at it here

user136984

22:38

AIM?

Peret Finctor

Meeeh...

Thomas W.

AOL Instant Messenger

Zacharee1

@ThomasW. ai dunt

creng

Peret Finctor

Anybody sets manually file permissions for anything?

user136984

Oh... No, I don't do all this slang and text talk stuff...

Thomas W.

22:38

@PeretFinctor Frequently

Fabby

@ParanoidPanda I did leave and come back.

I've got a few tabs open

Thomas W.

@PeretFinctor Why?

user136984

Oh, well I got it earlier and I hadn't left! :D

Peret Finctor

@ThomasW. Files in your home directory, or somewhere else?

Thomas W.

@PeretFinctor All across the system

@PeretFinctor you're talking to a power user who does development stuff too, so i frequently have to mess with permissions in different directories over my systems

if you have a real question ask it

otherwise i'm going to go do something productive

(E: Specified resource 'Thomas W.' has limited or zero tolerance for generic questions that don't really ask anything)

user139252

22:41

@daBoss How well does it work?

user136984

Oh dear... I've got a cough and a sore throat... I think I'm coming down with something... :(

da Boss

Basically you install it, then set your computer to use it as a DNS...

then you go from....

Thomas W.

@ParanoidPanda You need this... passes @ParanoidPanda /dev/dayquill and /dev/nyquill

Peret Finctor

@ThomasW. What do I have to know about file permissions to say to miself "Yes, I got it, I know this topic completely"?

da Boss

to...

Thomas W.

22:42

@PeretFinctor If you have to ask you're never going to be able to learn it

da Boss

user139252

Amazing!

Thomas W.

@PeretFinctor linuxquestions.org/linux/answers/Security/…

Fabby

@PeretFinctor yes, off course...

@ThomasW. How are you doing??? ;-)

Thomas W.

@PeretFinctor You also won't always know the topic completely. Basic perms, read man chmod. That's the absolute basics. Though, you have to now handle ACLs, other filesystem controls, etc. and that constantly expands/changes

ESPECIALLY when you take into account network share permission configurations, etc.

and permissions applied to mounting of drives (manually, fstab, or otherwise)

Fabby

22:44

@PeretFinctor Start by reading the FHS

Thomas W.

it's not a subject you just 'learn'

agree with Fabby as well

Peret Finctor

@ThomasW. I think I need to look at some examples of it's usage. Real-life examples.

Thomas W.

@Fabby BURN THE WINDOWS USERS UNTIL THEY ARE DUST AND SUBATOMIC PARTICLES, AND NOTHING MORE.

chili555

sudo chmod +dust

Fabby

@ThomasW. Quark dust? ;-)

Thomas W.

22:45

@PeretFinctor Infinite, unattainable. Reading through manpages and how they work is just as effective, and you can then 'test' things to learn in a temporary directory or in a virtual machine

user139252

I really want to make fun of a user's name...

Thomas W.

@HeatherBrown ... but you won't since you may get flagged as "rude or offensive"

user139252

I know.

user136984

@HeatherBrown: Which user? :D

Peret Finctor

@ThomasW. Example of when you last changed permissions of something inside your home directory? Do you need to ever change something there (apart of maybe making some shell script executable sometimes)?

Thomas W.

22:49

@PeretFinctor (1) Today, to make nginx work from a home directory doc root

Fabby

@PeretFinctor When I wanted my admin user to have write access to a file of my user user is my last example...

Thomas W.

(2) frequently, with custom installer scripts I write, or files that need multiple system users to be able to read/write

Seth

who keeps starring uninteresting stuff -.-

Thomas W.

@Seth You do?

Seth

I haven't starred anything in a few days.

Fabby

22:50

@Seth All these [damn kids]() in here?

All these damn kids in here! ;-)

user136984

Do you think that 16.04 will have changed much yet?

Thomas W.

@ParanoidPanda define 'changed' lol

remember, 'broad questions' are bad

Peret Finctor

Root user always can access everything... So, chowning some file or folder to root:root is like saying "Nobody owns it"

user136984

Well, I guess I'm about to find out (I'm installing a daily build)! :D

Thomas W.

@PeretFinctor No, wrong, that means that only the superuser owns it.

there is no 'nobody owns it' state, i believe

da Boss

22:57

@HeatherBrown it is amazing, and super easy...

@HeatherBrown and cheap...

user136984

@ThomasW.: I mean will I be able to immediately tell the difference between it and 15.10? I guess not so much yet but I don't know how fast it develops...

da Boss

And I believe the sites still get ad-revenue because the ads just get intercepted by the rpi.

Thomas W.

@ParanoidPanda There's been a bunch of work but I think all Ubuntu is basically 'similar enough to not immediately nor easily tell' which version you're on

Peret Finctor

@ThomasW. Well, there is no point in it already. Even if there was a way as to set a file to be owned by noone, root would still had access to it. It would've been the same thing. I'm just talking to myself 15 minutes above.

If not sure which user to make an owner, give it to root.

user139252

@daBoss I was having issues with it. I tried installing it on one of my RPis that was attached to the VPN. Lost all name resolution.

Peret Finctor

23:00

This way I can ignore existance of groups for now. I'll just set all groups to root.

user139252

I'm thinking the Pi needs to be on the same network as my VPN server, but not attached to the actual VPN.

da Boss

@HeatherBrown oh, I don't know, I have never tried to set it up with VPN in the middle...

Peret Finctor

I have so many users on my system, and I have no idea what any of those does.

Didn't know they even existed until today.

Nah, I'll delete the system soon, it doesn't matter that much.

user136984

@ThomasW.: Well, it seems a very large ISO so I may not test it tonight, plus I like the next release to be a surprise! :D

Peret Finctor

Root can read any file, no matter what permissions it has, right?

read and write and delete and whatever

Zacharee1

23:05

Should be

Peret Finctor

ok...

I like the way you smile.

Fabby

@PeretFinctor yes!

user139252

Fabby

@Zacharee1 --^not should be

@HeatherBrown !

Zacharee1

@Fabby Well idk for sure

user139252

23:10

@PeretFinctor Who was smiling?

terdon

I want to buy a replacement HDD for a dead laptop (Dell Precision M4500). I am looking at SATA II and III and would obviously prefer III. Are the two compatible? Can I safely assume that the laptop can deal with a SATA III?
If not, how can I tell whether the HDD (which is now in an external case being abused by ddrescue) is a SATA II or III?

Peret Finctor

@Doen't matter

Fabby

Under windows, you can cut out the Administrator from anything, under Linux you cannot disallow root access... (except by encryption)

Peret Finctor

@Fabby interesting.

Fabby

@terdon Do you have the model number of the HDD?

terdon

23:14

I'm trying to get it. I didn't check it before putting it in the external enclosure and my system doesn't see it too well.

Fabby

You actually close an enclosure?

You don't let the failing HDD run naked?

(to better dissipate heat?)

terdon

Good point. But yes, I've closed it.

Kinda had to actually, the USB port is on the door of the enclosure, not sure if it would work if I left it open.

Fabby

@terdon It does...

terdon

Oh well... :)

Fabby

I used to have just the control circuit of an USB enclosure in my laptop bag until I moved over to Ubuntu...

Now I have a lubuntu bootable USB stick to disinfect Windows Computers...

;-)

Ping me when you need me: I'm reviewing...

terdon

23:23

Joy!

Zacharee1

lol

Fabby

@terdon looks like a failing HDD...

And that's the disadvantage of the GUI: you can't see what % it already has:

terdon

@Fabby Oh, no, that's a failed HDD, not a failing one.

Fabby

If it has 99,9%, you can abort and just live with a few lost files...

terdon

I dropped the laptop while using it. 'S the problem of using a laptop when in bed with reduced mobility due to a broken knee :(

Fabby

23:25

@terdon Broken knee?

terdon

@Fabby See that empty bar at the bottom with a tiny blue line? That's the percentage.

Fabby

SSD is the answer to that...

terdon

@Fabby Yeah, healed now. I broke it last december.

Fabby

@terdon Ah! I thought you broke your other one...

Zacharee1

Chainfire has made a 6.0 root that doesn't edit /system

Fabby

23:26

@terdon Do you know what SpinRite is???

Zacharee1

Now he just needs to get the Note 4 rooted....

terdon

No, I just never got around to attempting to save anything from that drive. Almost everything was backed up but there were a couple of things I wanted to salvage.

Fabby

(WARNING: ---^ COMMERCIAL SOFTWARE)

Peret Finctor

Placing a 0 in the chmod 0755 was once abligatory, wasn't it? Like, base 8?

/me digging in some old makefiles.

terdon

@Fabby Nope. Something better than ddrescue for what I'm trying to do?

Peret Finctor

23:27

@ThomasW. ?

Fabby

@terdon Yup... And it comes with a money-back guarantee!!!

@terdon grc.com

Which means it needs to take my money first. :(

I once used a laptop with a dying hard drive for quite a few months, nothing important on it, kept blocking out sectors and Linux did quite fine making the partition read only off and on

Fabby

@terdon Do you have tox?

terdon

23:29

@Terrance Thanks but 100$ and Windows only.

Zacharee1

@PeretFinctor I don't think it was like that on Ubuntu, but I could be wrong

terdon

@Fabby No.

user136984

@Fabby: In Tools > Suggested Edits, what is the "Controversial" category and what does it indicate?

Fabby

@terdon It's actually using a linux boot loader...

Mateo

there is a good utility on the system rescue CD

Fabby

23:30

the exe is just a self-extracting zip file...

Terrance

@terdon Yeah, but it has recovered soooo many drives for me in the past. If it cannot recover the sectors then the drive is toast! Just a suggestion.

user136984

Does anybody else get this error for this page?

user136984

Fabby

@ParanoidPanda I forgot and am too lazy to look...

Mateo

MHDD was the tool, can scan for bad blocks

terdon

23:31

@Terrance Thanks. I don't think it's worth 100$ in my case, most of my stuff was backed up.

Zacharee1

@ParanoidPanda I need more privileges

terdon

@Mateo Probably ddrescue.

Fabby

@ParanoidPanda looks like it!

@Zacharee1 You call that a review??? :P

user136984

Well, goodnight folks! :)

@Zacharee1 I use this one:

`So please first look over the existing answers and if none of them work, ask a new question and refer back to this question and explain what went wrong. **;-)**``

Terrance

@terdon You could always run the freebie to see if it can regenerate at least letting you know if the drive can be recovered or not.

terdon

23:37

@Fabby Not really, no. But I will have tox in a bit.

Zacharee1

@Fabby I'm too lay to put that into some sort of clipboard

terdon

@Terrance Hmm. That might be worth it, yeah.

Fabby

@Zacharee1 In a few days all of my custom comments will be in the autocomments...

I need a program, which is callable by any user, and have a bunch of files and folders which only it should access. What is better for that, setting program to setuid and everything to games:root, or program to setgid and everything to root:games?

Overly enthused about the new job. No stress. Simple rules. The only bad thing is the commute, but hell. I'll take it.

terdon

@Fabby Still installing. One of the major drawbacks of AUR and Arch. Installing stuff takes a good while longer.

Peret Finctor

@hbdgaf interesting.

terdon

@hbdgaf Yay! I hadn't heard you'd switched jobs. Given the crap the previous one put you though, that sounds like a wonderful change.

Seth

@terdon unless you've got tons of CPU power (dual Xeons anyone?)

Fabby

@terdon Oh yeah: you're on arch!

hbdgaf

23:50

@terdon Totally is. I followed my old boss to his new company/store. Better company.

Peret Finctor

@terdon That's nothing difficult, really.

terdon

@PeretFinctor What isn't?

@hbdgaf Nice!

Fabby

@hbdgaf Good! What kind of hardware are you into now?

@terdon Milkdron for example. You should try it once.

@Fabby It's Burlington Coat Factory. I'm just floating right now. I'm basically doing the "notes machine" role. Where when something big needs to get done, they leave everyone on task and let me handle broad strokes.

Nah. It's easy stuff. Different companies just have different standards for different things. No pressure. Just "Do this. You know what I want it to look like. I'll be back in a couple hours."

Fabby

23:56

How do your new colleagues look at all that going on???

hbdgaf

They seem to like me, because they don't have to carry the weight of doing something they don't understand without having seen it look that way before. Everyone is really nice, but some of them are giving me the "Who the hell is this guy" smile if you know what I mean.
