Paranoid much? In my experience WINE viruses are not really a problem.

Re: I like to know meaning of groups in Linux

@topiwala
2 problem with firejail:

1) not available neither in Fedora repositories nor in RPMFusion repositories. Only in coper. Why such great application not available, I do not understand !

2) I do not use Wine only for games. I use it for PDF editor & irfanview. So, does isolation (sandboxing) such applications by firejail allow them to be still productive ? If irfanview isolated by firejail, then does it will be still able to handle & edit images ?

@flyingdutchman
I'm very unlucky man in my life, & I expect that bad things that are rare & uncomon to face me as rain of stones over my head ! This is what called bad luck ! I'm of that type ...

Re: I like to know meaning of groups in Linux

i agree not having it in official repos is a problem but i use this solution

a- i compile. It is easy as compared to other programs
b- to keep me updated i use RSS feed. Firejail page has Atom feed.

As for second problem i haven't used those programs.

Now a days i do not even install wine.

WineHQ & Anbox are 2 great tools ! Wine make you able to use Windows applictions on Linux. If you observing change log of wine, you will see that versions 2+ started to add very important features, so that version 3 will be very good. I suspect that version 4 at 2019 will be excellent.

Regarding anbox:

https://anbox.io

it is still alpha. It enable you to run Android applications on Linux in exetra ordinary way ! It is secure by default !

No other OS like Linux in it's elasticity !

Re: I like to know meaning of groups in Linux

My experience with wine was "difficult".

Regarding Anbox, please beware that currently there is something you should download & install manually to install Anbox on Fedora - read their forum or bug, I do not remember exactly .... Test it on Debian is better, as I think .... It is still ALPHA !

I'm like you, mostly Linuxer, now ! But game ! There are very nice windows games not available on Linux ......

Re: I like to know meaning of groups in Linux

Hi User808
Everyone has access to the su command.

Only a wreckless administrator or an adminstrator with poor linux/security knowledge will give that user the root password.

Once that user is given the root password, he can edit /etc/group and add his login to the wheel group.
That is why we allow sudo. And yes, with sudo you do not have to give total system access . You can even manage printing, file allocation, and commands that you want to remain privileged.

This is bad ! FreeBSD do not allow this. I think every new user added should be by defsult has no sudo, no su powers + unable to gain root from within any GUI including Gnome software.

Re: I like to know meaning of groups in Linux

Why is it bad? Just having access to su doesn't give you access to root because you still need to know root's password. And, although you can also use su to become some other user, you still need that user's password. Also, in Fedora (and I think Ubuntu) only the first user you create is added to wheel by default. If you don't want anybody else to have access to root, don't add them to wheel and don't tell them the root password.

What it will be the case if Wine dependent virus has build in tool for spantanous password generator & thus will trying to crack su password ? This is what I concerned about.

Let we return to topic of this thread. Do any one used "nobody" group & no more about what happened for user added to this group ?

True, but why bother? Once you have the root password, you don't need sudo. As an example, the only reason I have it installed on my computer is that there are packages that need it, because I certainly don't. Whenever I need root, I use su.
