To be fair, I reversed the two commands from Gene's email. He did the chmod 1777 first, and the chown second. So, yes, he would have needed the sudo on both of them. The point remains that putting 1777 perms on things at random is a horribly bad idea. A typical directory should have 755 perms at most. Gene didn't show us what the perms were originally. All he showed was a plain "ls" listing of the parent directory, showing the name of the mount point, but none of its metadata. A reasonable starting point, given the error message that Gene received, would have been: ls -ld /the/directory Look at the owner. Is it correct? If not, fix it. Look at the permissions. Are they correct (drwxr-xr-x)? If not, fix them. Don't just randomly throw 1777 or 777 or 666 permissions on everything.
