About Samba

Samba is the standard Windows interoperability suite of programs for Linux and Unix. Samba is Free Software licensed under the GNU General Public License and the Samba project is a member of the Software Freedom Conservancy. Since 1992, Samba has provided secure, stable and fast file and print services for all clients using the SMB/CIFS protocol, such as all versions of DOS and Windows, OS/2, Linux and many others. Samba is an important component to seamlessly integrate Linux/Unix Servers and Desktops into Active Directory environments. It can function both as a domain controller or as a regular domain member.

For the AD DC implementation a full HOWTO is provided at: https://wiki.samba.org/index.php/Samba4/HOWTO

Community guidelines can be read at: https://wiki.samba.org/index.php/How_to_do_Samba:_Nicely

This software is freely distributable under the GNU public license, a copy of which you should have received with this software (in a file called COPYING).

CONTRIBUTIONS

Please see https://wiki.samba.org/index.php/Contribute for detailed set-by-step instructions on how to submit a patch for Samba via GitLab.

Samba's GitLab mirror is at https://gitlab.com/samba-team/samba

OUR CONTRIBUTORS

See https://www.samba.org/samba/team/ for details of the Samba Team, as well as details of all those currently active in Samba development.

If you like a particular feature then look through the git change-log (on the web at https://gitweb.samba.org/?p=samba.git;a=summary) and see who added it, then send them an email.

Remember that free software of this kind lives or dies by the response we get. If no one tells us they like it then we'll probably move onto something else.

MORE INFO

DOCUMENTATION

There is quite a bit of documentation included with the package, including man pages and the wiki at https://wiki.samba.org

If you would like to help with our documentation, please contribute that improved content to the wiki, we are moving as much content there as possible.

MAILING LIST

Please do NOT send subscription/unsubscription requests to the lists!

There is a mailing list for discussion of Samba. For details go to https://lists.samba.org/ or send mail to samba-subscribe@lists.samba.org

There is also an announcement mailing list where new versions are announced. To subscribe go to https://lists.samba.org/ or send mail to samba-announce-subscribe@lists.samba.org. All announcements also go to the samba list, so you only need to be on one.

For details of other Samba mailing lists and for access to archives, see https://lists.samba.org/

MAILING LIST ETIQUETTE

A few tips when submitting to this or any mailing list.

  1. Make your subject short and descriptive. Avoid the words "help" or "Samba" in the subject. The readers of this list already know that a) you need help, and b) you are writing about samba (of course, you may need to distinguish between Samba PDC and other file sharing software). Avoid phrases such as "what is" and "how do i". Some good subject lines might look like "Slow response with Excel files" or "Migrating from Samba PDC to NT PDC".

  2. If you include the original message in your reply, trim it so that only the relevant lines, enough to establish context, are included. Chances are (since this is a mailing list) we've already read the original message.

  3. Trim irrelevant headers from the original message in your reply. All we need to see is a) From, b) Date, and c) Subject. We don't even really need the Subject, if you haven't changed it. Better yet is to just preface the original message with "On [date] [someone] wrote:".

  4. Please don't reply to or argue about spam, spam filters or viruses on any Samba lists. We do have a spam filtering system that is working quite well thank you very much but occasionally unwanted messages slip through. Deal with it.

  5. Never say "Me too." It doesn't help anyone solve the problem. Instead, if you ARE having the same problem, give more information. Have you seen something that the other writer hasn't mentioned, which may be helpful?

  6. If you ask about a problem, then come up with the solution on your own or through another source, by all means post it. Someone else may have the same problem and is waiting for an answer, but never hears of it.

  7. Give as much relevant information as possible such as Samba release number, OS, kernel version, etc...

  8. RTFM. Google.
