[SOLVED] Access directory placed in another directory without permiss

860lacov · 2021-01-23 14:06:19

Two users
jm
mag_ja

The Structure looks like this:

~/home/jm/Vbox/vmmachine.vbox

I would like to give mag_ja an acces to Vbox directory.

I changed ownership for Vbox from jm:jm to jm:vboxusers
jm and mag_ja are in vboxusers group

I would like to run VirtualBox on mag_ja accout and add there vmmachine.vbox
But jm home has an ownership set to jm:jm

Is it possible to make this work withot changing full path "~/home/jm/Vbox/vmmachine.vbox" to jm:vboxusers
?

You can be *in* that directory, but you can't traverse the directory you don't have sufficient permissions for.

You could bind-mount ~/home/jm/Vbox (sidebar: is that the *actual* path, ie. do you have a directory /home/jm/home/jm ? - "~" is shorthand for $HOME which is typically /home/<your user name> …)

sudo mount -o bind /home/jm/Vbox /home/mag_ja/VBox # this assumes /home/mag_ja/VBox exists and sane $HOME directories

nb. that mag_ja will also require proper access to all files in there, eg. vmmachine.vbox

The directory is VirtualBox VMs and actuall path is:
~/VirtualBox VMs
As you said mag_ja

will also require proper access to all files in there, eg. vmmachine.vbox

mag_ja is in vboxusers gruop
I did

sudo mount -o bind /home/jm/VirtualBox\ VMs/ /home/mag_ja/VirtualBox\ VMs/

and

chown jm:vboxusers -R /home/jm/VirtualBox\ VMs/

I can access Virtual Box machines on both accounts but mag_ja can't open machine in virtual box because of privileges problem. Any advice about this?

p.s.
By mistake, I reported your answer. Sorry for that.

No worries

I'd guess the relevant files are not group writable. Post the actual error messages as well as the current permissions of the file(s) in question.

Of course, you are right.
vboxusers group didn't have write permission.

I managed after change to 660 I was able to add virtual machine to virtual box on mag_ja accout but I wasnt able to run it.
After reboot machine diapered from mag_ja VirtualBox VMs directory.
Is

mount -o bind

only temporary?

Every mount is "temporary" (transient) - you'll have to add an entry to /etc/fstab (the order is important! if there's a mount for /home, put the bind mount below that line)
