進展飛快的 FreeBSD 使得現有的印刷、平面媒體跟不上它的最新進度! 反而數位版本的資源,也許有時並不是最好,但通常是唯一一個跟上最新進展的方式。 正由於 FreeBSD 是來自於許多志工的努力,所以廣大的使用者群也通常扮演著 “IT技術支援部門” 的角色。 只要善用電子郵件和 USENET 新聞群組就可以很快速地聯繫這些社群了。

以下簡介與 FreeBSD 社群搭上線的主要方式。 若你還知道其他這裡沒有列出的資源,請告知 FreeBSD documentation project 郵遞論壇,以便我們更新。

C.1. 郵遞論壇(Mailing Lists)

雖然,大部份的 FreeBSD 開發人員都有看 USENET 新聞群組, 我們也不能保證我們永遠可以及時得知您的問題。 尤其是,若您只在 comp.unix.bsd.freebsd.* 其中群組內發問的話。 建議您將問題發到適當的郵遞論壇(mailing list)上,不但可以同時讓 FreeBSD 開發者和其他看倌們知道,通常也可以得到一個較好的(最起碼會比較快)的回應。

本文後面介紹的是各式不同的郵遞論壇、討論規則(charter)。 在訂閱任何 list 之前,請先閱讀討論規則。 訂閱這些 list 的人們現在每天都會收到數百封 FreeBSD 相關信件。 而討論規則的制訂,則有助於提升彼此討論品質。 否則,這些討論 FreeBSD 的 list 終將陷入溝通不良,而失去其原本美意。

對於該在哪個 list 發問覺得很疑惑的時候,就來看看 《如何在 FreeBSD-questions mailing list 上得到正解》 一文吧

在發表問題、回覆到 list 之前,請先讀過 FreeBSD Mailing Lists 常見問答集(FAQ) 一文以學會如何善用 mailing list ,才能避免像是經常重複的月經文、戰文之類的事情發生。

全部的 mailing lists 討論記錄都可以在 FreeBSD WWW主機 上找到。它提供了很棒的關鍵字搜尋功能,可讓您找到常用問答集(FAQ) 。而在 mailing lists 上發問之前,也請先搜尋是否已有解答。

C.1.2. 要如何訂閱

要訂閱 list 的話,請以滑鼠按下上述 list 名稱, 或是到 http://lists.FreeBSD.org/mailman/listinfo 然後即可挑選有興趣的 list 來訂閱了, 該網頁會指示你如何進行訂閱的步驟。

To actually post to a given list you simply send mail to . It will then be redistributed to mailing list members world-wide.

To unsubscribe yourself from a list, click on the URL found at the bottom of every email received from the list. It is also possible to send an email to to unsubscribe yourself.

Again, we would like to request that you keep discussion in the technical mailing lists on a technical track. If you are only interested in important announcements then it is suggested that you join the FreeBSD announcements 郵遞論壇, which is intended only for infrequent traffic.

C.1.3. List Charters

All FreeBSD mailing lists have certain basic rules which must be adhered to by anyone using them. Failure to comply with these guidelines will result in two (2) written warnings from the FreeBSD Postmaster , after which, on a third offense, the poster will removed from all FreeBSD mailing lists and filtered from further posting to them. We regret that such rules and measures are necessary at all, but today's Internet is a pretty harsh environment, it would seem, and many fail to appreciate just how fragile some of its mechanisms are.

Rules of the road:

  • The topic of any posting should adhere to the basic charter of the list it is posted to, e.g. if the list is about technical issues then your posting should contain technical discussion. Ongoing irrelevant chatter or flaming only detracts from the value of the mailing list for everyone on it and will not be tolerated. For free-form discussion on no particular topic, the FreeBSD chat 郵遞論壇 is freely available and should be used instead.

  • No posting should be made to more than 2 mailing lists, and only to 2 when a clear and obvious need to post to both lists exists. For most lists, there is already a great deal of subscriber overlap and except for the most esoteric mixes (say “-stable & -scsi”), there really is no reason to post to more than one list at a time. If a message is sent to you in such a way that multiple mailing lists appear on the Cc line then the Cc line should also be trimmed before sending it out again. You are still responsible for your own cross-postings, no matter who the originator might have been.

  • Personal attacks and profanity (in the context of an argument) are not allowed, and that includes users and developers alike. Gross breaches of netiquette, like excerpting or reposting private mail when permission to do so was not and would not be forthcoming, are frowned upon but not specifically enforced. However, there are also very few cases where such content would fit within the charter of a list and it would therefore probably rate a warning (or ban) on that basis alone.

  • Advertising of non-FreeBSD related products or services is strictly prohibited and will result in an immediate ban if it is clear that the offender is advertising by spam.

Individual list charters:

freebsd-acpi

ACPI and power management development

freebsd-afs

Andrew File System

freebsd-announce

Important events / milestones

This is the mailing list for people interested only in occasional announcements of significant FreeBSD events. This includes announcements about snapshots and other releases. It contains announcements of new FreeBSD capabilities. It may contain calls for volunteers etc. This is a low volume, strictly moderated mailing list.

freebsd-arch

Architecture and design discussions

This list is for discussion of the FreeBSD architecture. Messages will mostly be kept strictly technical in nature. Examples of suitable topics are:

  • How to re-vamp the build system to have several customized builds running at the same time.

  • What needs to be fixed with VFS to make Heidemann layers work.

  • How do we change the device driver interface to be able to use the same drivers cleanly on many buses and architectures.

  • How to write a network driver.

freebsd-audit

Source code audit project

This is the mailing list for the FreeBSD source code audit project. Although this was originally intended for security-related changes, its charter has been expanded to review any code changes.

This list is very heavy on patches, and is probably of no interest to the average FreeBSD user. Security discussions not related to a particular code change are held on freebsd-security. Conversely, all developers are encouraged to send their patches here for review, especially if they touch a part of the system where a bug may adversely affect the integrity of the system.
