I'll try again with a shorter message. I'm having problems executing programs from a mounted USB drive. I mount /dev/sda1 to /dev/usb and create some directories over there. All paths have execute access all the way down When I try to execute a program built on the USB drive, I get "bash: /mnt/usb/jmccarty/hello: Permission denied". Is this because it is a "removable medium"? I just checked, and I get the same error from a floppy. Earlier I wrote >So why is permission denied? It's not just that it's removable >medium. So is the floppy, but I can execute from there. I must have been thinking about from my DOSEMU (which can and does execute DOS images from both floppy and USB drives). Mike -- p="p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);} This message made from 100% recycled bits. I can explain it for you, but I can't understand it for you. I speak only for myself, and I am unanimous in that!
