1921 | This is the client VFS module for the Common Internet File System | ||
1922 | (CIFS) protocol which is the successor to the Server Message Block | ||
1923 | (SMB) protocol, the native file sharing mechanism for most early | ||

1925 | file servers such as Windows 2000 (including Windows 2003, NT 4 | ||
1926 | and Windows XP) as well by Samba (which provides excellent CIFS | ||
1927 | server support for Linux and many other operating systems). Limited | ||
1928 | support for OS/2 and Windows ME and similar servers is provided as | ||
1929 | well. | ||
1930 | |||
1931 | The cifs module provides an advanced network file system | ||
1932 | client for mounting to CIFS compliant servers. It includes | ||
1933 | support for DFS (hierarchical name space), secure per-user | ||

1935 | safe distributed caching (oplock), optional packet | ||

1964 | Modern CIFS servers including Samba and most Windows versions | ||
1965 | (since 1997) support stronger NTLM (and even NTLMv2 and Kerberos) | ||
1966 | security mechanisms. These hash the password more securely | ||
1967 | than the mechanisms used in the older LANMAN version of the | ||
1968 | SMB protocol but LANMAN based authentication is needed to | ||
1969 | establish sessions with some old SMB servers. | ||
1970 | |||
1971 | Enabling this option allows the cifs module to mount to older | ||
1972 | LANMAN based servers such as OS/2 and Windows 95, but such | ||
1973 | mounts may be less secure than mounts using NTLM or more recent | ||
1974 | security mechanisms if you are on a public network. Unless you | ||
1975 | have a need to access old SMB servers (and are on a private | ||
1976 | network) you probably want to say N. Even if this support | ||
1977 | is enabled in the kernel build, LANMAN authentication will not be | ||
1978 | used automatically. At runtime LANMAN mounts are disabled but | ||
1979 | can be set to required (or optional) either in | ||
1980 | /proc/fs/cifs (see fs/cifs/README for more detail) or via an | ||
1981 | option on the mount command. This support is disabled by | ||
