Share folders cannot execute files

[strategist333]

On Ubuntu 8.04, I'm having a bit of trouble allowing g++ compilation in my shared folder to execute. I currently have my mount call as

sudo mount -t vboxsf -o rw,exec,uid=1000,gid=1000 share /mnt/share

When I go in Nautilus to view the properties of the executable, I can't check the 'Allow executing file as program' option under Permissions. I also can't do this for the cpp file that I'm trying to compile. Copying the executable onto my desktop allows me to check the option, after which I can then run the program.

Is there some option I'm missing in the mount call that is preventing all files from being able to execute? I'm using VirtualBox 1.6.4 on Vista Premium 32 as host.

I thought it was copying the permission off the host's file system and is not changeable on the guest. (Ends up as 777 if host is on FAT) Shared folder feature is rather limited imo.

You can probably have better luck mounting host with cifs, then you can change permissions (although, if you remount, all of the specified permissions will be reverted)

Did you check the permissions from within a Terminal? If you do an ls -l you will see the mask of the files. It should note -rwx-rwx-rwx for the file. Shared Folders are like network shares, you can't change the mask on the files.

Except, nfs or cifs can but not vboxsf.
Btw it should look '-rwxrwxrwx' if it is 777.

What file system on the host are you mounting?

[strategist333]

Using ls -l, I get -rw-rw-rw for all files in /mnt/share (my mountpoint).

EDIT: Interestingly, with ls -all, I see that the folder . has permissions drwxrwxrwx

My host is using NTFS. Is there some option I need to set in Windows to get the x to show up?

I just checked with my Ubuntu Server VM to see what my mount options are, and they are as following:

Code: Select all

Entry in /etc/fstab
data  /data  vboxsf  defaults,gid=1000,uid=10000,auto,rw

My data partition on my Host is NTFS (Host is Ubuntu 8.04, Guest is 8.04 server). Now when I do an ls -l /data I get the following:

Code: Select all

-rwxrwxrwx 1 sasquatch sasquatch  452  2008-06-28 12:06 New Text Document.txt

This entry is for all files I have on the mount point.

Pretty crazy if you ask me...

If the guest has ssh access to someone else, then all your files are owned...
Btw it's 'ls -al' you don't need 'l' twice. But my recommendation for 'ls' is '-aCFhl'
