Question #: 48
Topic #: 2

Part 1 (on Node1 Server)

Task 4 [Controlling Access to Files]

Create collaborative directory /mnt/shares with the following characteristics:

Group ownership of /mnt/shares should be sharegrp.

The directory should be readable, writable and accessible to member of sharegrp but not to any other user. (It is understood that root has access to all files and directories on the system)

Files created in /mnt/shares automatically have group ownership set to the sharegrp group.

AExplanation:
*
[root@node1 ~]# mkdir -p /mnt/shares
[root@node1 ~]# ls -lrt /mnt/
[root@node1 ~]# chgrp sharegrp /mnt/shares/
[root@node1 ~]# chmod 2770 /mnt/shares/
[root@node1 ~]# ls -lrt /mnt/
### For Checking ###
[root@node1 ~]# su - harry
[harry@node1 ~]$ cd /mnt/shares/
[harry@node1 shares]$ touch harry
[harry@node1 shares]$ logout
[root@node1 ~]# su - natasha
[natasha@node1 ~]$ cd /mnt/shares/
[natasha@node1 shares]$ touch natasha
[natasha@node1 shares]$ ls -lrt
-rw-rw-r--. 1 harry sharegrp 0 Mar 21 06:03 harry
-rw-rw-r--. 1 natasha sharegrp 0 Mar 21 06:03 natasha

I thought root could access everything, but this setup seems tricky!

Nice, but what if someone forgets to set the group on new files?

Wait, does that mean others can't access it at all?

Totally agree, chmod 2770 is spot on!

I recall that files created in the directory should inherit the group, but I’m not clear on how that works with the `chmod` command.

I’m a bit confused about the sticky bit. Do we need to set it here, or is it just the `setgid` bit that we need for the group ownership?

I practiced a similar question where we had to set permissions, and I think using `chmod 2770` is correct for allowing group access while restricting others.

I think I remember that we need to set the group ownership with `chgrp`, but I'm not entirely sure if I need to check the current group first.

I'm a bit confused by the terminology here. What's the difference between an "Archive Job" and a "Backup Copy Job"? I'll need to think this through step-by-step.

I'm a little confused by the options here. I'll need to review my notes on storage technologies to make sure I understand the differences between them.

I'm not entirely sure about this one. I'll need to think it through carefully and maybe even do a quick search to make sure I have the right understanding before answering.

Wait, what is iBMC? I've never heard of that before. I'm a bit confused by this question. I'll have to guess and hope for the best.
