Restricting one member of a group from accessing a file

cmunger · 03-10-2014, 11:50 AM

Hey guys,

Im working in the RHCSA review book I have again, so bear with me on these questions.
I am trying to set the permissions on a file to allow group access to rwx, but restrict one certain member of the group from having any access.

User1, user2, and user 3 are part of GroupA.
I need to allow GroupA full rwx on file_A, but NOT allow user2 any privledges to the file (no rw or x).

I cant wrap my head around how this is supposed to work.

Thanks in advance for the help, and yalls time.

Check file ACLs

--C

What's the point in having all of the members part of the same group when they do not all have the same access to files in that group?

Personally I would make two groups, maybe "level1" and "level2". Add all users to the level1 group, and everybody except the restricted user to the level2 group, then set your file permissions appropriately.

I know this doesn't answer the specific scenario you have from the book, but it sounds like a pretty dumb scenario to begin with

I have no idea how I missed that. It was staring me in the face, and I couldnt even register it as what I needed. Thank you so much.

Not only is that a ton simpler, but it makes sense for the work world. But like I said, its a review book for the RHCSA exam. Ive noticed a ton of this stuff doesnt make much application sense.
