No problems Simon. I'd also suggest having a read through the first few chapters of this book: http://www.samba.org/samba/docs/man/Samba-Guide/ It's available both in paper for purchase (all proceeds go back to the Samba dev team) or online. I have it in book format, and find it one of the most useful resource books around. Instead of waffling on about theoretical setups, it gives practical examples starting off from a small home-office with a few people, right up to a multi-site, fully authenticated enterprise. It covers all aspects of a Samba setup from the technological requirements through to the political pitfalls. Included within are actual real-world smb.conf files (not just snippets or hard-to-read man files). I just can't recommend the book highly enough. If all technical books were written like this, people like me would be out of the job. :) - -Dan -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIon12eFJDv0P9Qb8RAqwpAKCq8cg+e6FXAZKyC1kbZGzqa5CbmgCgkerF R9jPXBX9e0/87ir0E2UFzok= =KoEM -END PGP SIGNATURE- -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au

The best way is to properly integrate your authentication systems, or at the very least ensure that user accounts that exist on the Windows machines also exist on the Linux machines and within Samba with the same passwords. i.e.: your windows username/password is also added to Linux via the "useradd" and "passwd" commands, and to Samba via the "smbpasswd - -a" command.

From the parent directory of the music directory the following needed to be typed: sudo chmod -R a+rw music Thanks for the assistance.

File Permissions - Ubuntu Server
I'm running Ubuntu Server 8.04 and I need to change the permissions for a large quantity of files and directories. I've got a directory named 'music' that I share with the home network. This includes other Linux boxes that access this directory via nfs and some Windows XP boxes accessing it via samba. I've just transferred around 80gb of music files and directories from a Windows drive and I need a command to alter the permissions of all the files as read/write for everyone. Further, is there a way that I can set all newly created directories and files within this particular directory to inherit the file permissions of the parent directory? Thanks.
