Tridgell Taking Samba Beyond POSIX
dW writes "The Australian hacker has been working on pushing Samba beyond the POSIX world and figuring out what work needs to be done to get Samba to support new filesystems such as XFS, ext3, and Storage Tank. The answer is nothing less than a complete rewrite of Samba's smbd code, which has become his latest pet project. Here's an interview with Andrew Tridgell on his latest Samba rewrite."
Samba's existence is vastly important to the adoption by corporate management of perceived 'alternate' computing systems (i.e., Linux, Mac, sometimes Unix, as opposed to Windows) in the datacenter. The simple fact that there exists an easy-to-use, open source method of interconnecting disparate file systems, allowing multiple OS co-existance, is often the lynchpin in convincing managers to permit non-Windows systems to be deployed in a company. I have worked in several situations where employees have wanted to use Mac OSX desktops or Linux/Unix servers (etc.) in an all-Windows shop, and managers balked at the idea until they were convinced that data could still be exchanged, and that the 'alternative' OS'es could still 'talk' to the Windows machines.
With this established managerial behavior in mind, isn't it interesting that IBM would have hired Samba's creator outright, to work on a project which furthers Samba's ability to communicate with additional operating systems? Samba in many ways is a 'license to change' computers in a datacenter for IT staff. IBM has positioned itself to pump funding directly into the Samba project, as well as to have a say in which file systems it supports; this gives IBM the ability to write its own ticket in terms of promoting its disparate filesystem architectures' usage in the datacenter, alongside their Windows brethren.
Who's working on polishing up that ActiveDirectory and Kerberos stuff so I can continue to use my samba based PDC with WinXP.
It's neat that he's extending the SMB protocol to support some more of the native features of the underlying filesystems.
But I'd wager the lions share of it's user base want samba to replace/supplement Win2k Server, and soon Win2003.
This always happens in open source. Projects get pulled in a new direction before they're completed. Developers always want to work on neat stuff and get bogged down in the academics, and it doesnt produce a truly functional result.
There's nothing that can be done about it, it's his time, his decision. Still, it sure would be nice for samba to be a full member of a Windows 2000 domain.
I don't need no instructions to know how to rock!!!!

else I'll be using NFS which is a much better protocol in every area.
Er, yes... like how NFS relies on the hostname for security, while SMB/CIFS relies on a password.
NFS is as (in)secure as the r* commands (rlogin, rcp, rsh). It relies on the client to authenticate the user, and the server only trusts certain clients (or anything pretending to be certain clients).
Now I'll admit, a good firewall should keep NFS safe. Under certain setups, even a good router should be enough. However, I prefer to think of a firewall as one layer of security - not my first, last, and only line of defense.
Although I'm not currently using it, AFS/Code seems to be a cross platform (win, mac, unix) secure replacement to NFS.
NFS might be a better protocol then SMB/CIFS in certain areas, but for security, SMB/CIFS wins (even the old versions of SMB that rely on plaintext passwords).
