At our university we have some computers in the "networking lab", that are configured to allow everybody to run nmap as root via /etc/sudoers. Could this be a security vulnerability?
I would like to write a simple backup script that saves some data to a FAT drive. Should I reformat the drive and use a better file system or is it possible to use rsync with FAT? If so, what problems might I run into? Would performance be a lot worse?
EDIT: This is on linux, didn't even know there was a rsync for windows. The sources are various file systems (it's a mess), and the destination is currently formatted with FAT32.
Thank you for your answers, I'll probably go for a reformat, since I'm not completely sure about the file sizes we'll have.
