I am trying to understand the NOEXEC flag when mounting.
I am having an execution issue within the /tmp directory on someone elses machine that I cannot access atm where the /tmp directory is mounted onto a different drive than '/' and NOEXEC is present. I wanted to try and recreate this scenario on my machine, but I do not have a second hard drive. I tried doing the following command:
mount --bind /test1 /test2
I then removed the
bind flag and added
NOEXEC in /etc/fstab. Then, I created a file in /test2 called test.sh where it just echos 'hello world'. I try and run it and it said 'permission denied'. I then ran
chmod 777 test.sh and was able to execute the file just fine. I thought that the NOEXEC flag should not allow me to execute anything?
mount --bind /test1 /test2 not the same as mounting from a completely different physical drive? As in /test1 and /test2 are on different drives?
