Samba 可以让win和unix共享文件的东东
Samba，是种自由软件，用来让UNIX系列的操作系统与微软Windows操作系统的 SMB/CIFS（Server Message Block/Common Internet File System）网络协定做连结。在目前的版本（v3），不仅可存取及分享SMB的资料夹及打印机，本身还可以整合入Windows Server的网域、扮演为网域控制站（Domain Controller）以及加入Active Directory成员。简而言之，此软件在Windows与UNIX系列OS之间搭起一座桥梁，让两者的资源可互通有无。
Samba 4.6.8 已发布，这是一个安全版本，主要解决以下问题：
CVE-2017-12150 (SMB1/2/3 connections may not require signing where they should)
CVE-2017-12151 (SMB3 connections don't keep encryption across DFS redirects)
CVE-2017-12163 (Server memory information leak over SMB1)
详情
CVE-2017-12150: A man in the middle attack may hijack client connections.
CVE-2017-12151: A man in the middle attack can read and may alter confidential documents transferred via a client connection, which are reached via DFS redirect when the original connection used SMB3.
CVE-2017-12163: Client with write access to a share can cause server memory contents to be written into a file or printer.
