I frequently encounter problems due to file ownership and permissions for the "system" files in /usr, /bin, /sbin/ /etc, and so forth. For example, when I type su Administrator cygwin responds /usr/bin/su: /bin/bash: Permission denied I know enough to have done mkpasswd -l >/etc/passwd mkgroup -l >/etc/group My CYGWIN variable is "ntsec,server" I use Windows XP and all my filesystems are NTFS. What is the recommended user.group ownership for the important files in /bin, /sbin, /usr, /etc, and so on? What are the recommended permission bits? -- David Arnstein arnstein@pobox.com -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
