        <title>DESCRIPTION</title>

        <para>This tool is part of the <citerefentry><refentrytitle>samba</refentrytitle>
        <manvolnum>7</manvolnum></citerefentry> suite.</para>

        <para>mount.cifs mounts a Linux CIFS filesystem. It
is usually invoked indirectly by
the <citerefentry><refentrytitle>mount</refentrytitle><manvolnum>8</manvolnum></citerefentry> command when using the 
"-t cifs" option. This command only works in Linux, and the kernel must
support the cifs filesystem. The CIFS protocol is the successor to the 
SMB protocol and is supported by most Windows servers and many other
commercial servers and Network Attached Storage appliances as well as 
by the popular Open Source server Samba.
        </para>

        <para>
        The mount.cifs utility attaches the UNC name (exported network resource)
        specified as <emphasis>service</emphasis> (using //server/share syntax,
        where "server" is the server name or IP address and "share" is the name
        of the share) to the local directory <emphasis>mount-point</emphasis>.
        </para>

        <para>
                Options to <emphasis>mount.cifs</emphasis> are specified as a comma-separated
list of key=value pairs. It is possible to send options other
than those listed here, assuming that the cifs filesystem kernel module (cifs.ko) supports them.   
Unrecognized cifs mount options passed to the cifs vfs kernel code will be logged to the
kernel log.

        </para>

        <para><emphasis>mount.cifs</emphasis> causes the cifs vfs to launch a thread named cifsd. After mounting it keeps running until
                the mounted resource is unmounted (usually via the umount utility).
        </para>

        <para>
                <emphasis>mount.cifs -V</emphasis> command displays the version of cifs mount helper.
        </para>
        <para>

                <emphasis>modinfo cifs</emphasis> command displays the version of cifs module.

                <listitem><para>specifies the username to connect as. If
                                this is not given, then the environment variable <emphasis>USER</emphasis> is used. This option can also take the
form "user%password" or "workgroup/user" or
"workgroup/user%password" to allow the password and workgroup
to be specified as part of the username.
                </para>

<note>
        <para>
        The cifs vfs accepts the parameter <parameter>user=</parameter>, or for users familiar with smbfs it accepts the longer form of the parameter <parameter>username=</parameter>.  Similarly the longer smbfs style parameter names may be accepted as synonyms for the shorter cifs parameters <parameter>pass=</parameter>,<parameter>dom=</parameter> and <parameter>cred=</parameter>.
        </para>

                <listitem><para>specifies the CIFS password. If this
option is not given then the environment variable
<emphasis>PASSWD</emphasis> is used. If the password is not specified
directly or indirectly via an argument to mount, <emphasis>mount.cifs</emphasis> will prompt
for a password, unless the guest option is specified.
</para>

<para>Note that a password which contains the delimiter
character (i.e. a comma ',') will fail to be parsed correctly
on the command line.  However, the same password defined
in the PASSWD environment variable or via a credentials file (see
below) or entered at the password prompt will be read correctly.

                rarely needed for mounting to newer servers, this option
                is needed for mounting to some older servers (such
                as OS/2 or Windows 98 and Windows ME) since when connecting
                over port 139 they, unlike most newer servers, do not
                support a default server name.  A server name can be up

        <title>SERVICE FORMATTING AND DELIMITERS</title>

        <para>
                It's generally preferred to use forward slashes (/) as a delimiter in service names. They are considered to be the "universal delimiter" since they are generally not allowed to be embedded within path components on Windows machines and the client can convert them to blackslashes (\) unconditionally. Conversely, backslash characters are allowed by POSIX to be part of a path component, and can't be automatically converted in the same way.
        </para>
        <para>
                mount.cifs will attempt to convert backslashes to forward slashes where it's able to do so, but it cannot do so in any path component following the sharename.

        <title>INODE NUMBERS</title>
        <para>
                When Unix Extensions are enabled, we use the actual inode
        number provided by the server in response to the POSIX calls as an
        inode number.
        </para>
        <para>
                When Unix Extensions are disabled and "serverino" mount option
        is enabled there is no way to get the server inode number. The
        client typically maps the server-assigned "UniqueID" onto an inode
        number.
        </para>
        <para>
                Note that the UniqueID is a different value from the server
        inode number. The UniqueID value is unique over the scope of the entire
        server and is often greater than 2 power 32. This value often makes
        programs that are not compiled with LFS (Large File Support), to
        trigger a glibc EOVERFLOW error as this won't fit in the target
        structure field. It is strongly recommended to compile your programs
        with LFS support (i.e. with -D_FILE_OFFSET_BITS=64) to prevent this
        problem. You can also use "noserverino" mount option to generate inode
        numbers smaller than 2 power 32 on the client. But you may not be able
        to detect hardlinks properly.

        <title>FILE AND DIRECTORY OWNERSHIP AND PERMISSIONS</title>

        <para> The core CIFS protocol does not provide unix ownership
information or mode for files and directories. Because of this, files
and directories will generally appear to be owned by whatever values the
uid= or gid= options are set, and will have permissions set to the
default file_mode and dir_mode for the mount. Attempting to change these
values via chmod/chown will return success but have no effect.</para>

        <para>When the client and server negotiate unix extensions,
files and directories will be assigned the uid, gid, and mode provided
by the server. Because CIFS mounts are generally single-user, and the
same credentials are used no matter what user accesses the mount, newly
created files and directories will generally be given ownership
corresponding to whatever credentials were used to mount the
share.</para>

        <para>If the uid's and gid's being used do not match on the
client and server, the forceuid and forcegid options may be helpful.
Note however, that there is no corresponding option to override the
mode. Permissions assigned to a file when forceuid or forcegid are in
effect may not reflect the the real permissions.</para>

        <para>When unix extensions are not negotiated, it's also
possible to emulate them locally on the server using the "dynperm" mount
option. When this mount option is in effect, newly created files and
directories will receive what appear to be proper permissions. These
permissions are not stored on the server however and can disappear at
any time in the future (subject to the whims of the kernel flushing out
the inode cache). In general, this mount option is discouraged.
        </para>

        <para>It's also possible to override permission checking on the client
altogether via the noperm option. Server-side permission checks cannot be
overriden. The permission checks done by the server will always correspond to
the credentials used to mount the share, and not necessarily to the user who is accessing the share.</para>

        <title>CONFIGURATION</title>
                <para>
The primary mechanism for making configuration changes and for reading 
debug information for the cifs vfs is via the Linux /proc filesystem.
In the directory <filename>/proc/fs/cifs</filename> are various 
configuration files and pseudo files which can display debug information.  
There are additional startup options such as maximum buffer size and number
of buffers which only may be set when the kernel cifs vfs (cifs.ko module) is 
loaded.  These can be seen by running the modinfo utility against the file
cifs.ko which will list the options that may be passed to cifs during module
installation (device driver load).
For more information see the kernel file <filename>fs/cifs/README</filename>.
