It
2 is usually invoked as <span><strong class="command">mount.smbfs</strong></span> by
3 the <a href="mount.8.html"><span class="citerefentry"><span class="refentrytitle">mount</span>(8)</span></a> command when using the
4 "-t smbfs" option. This command only works in Linux, and the kernel must
5 support the smbfs filesystem. </p><p>Options to <span><strong class="command">smbmount</strong></span> are specified as a comma-separated
6 list of key=value pairs. It is possible to send options other
7 than those listed here, assuming that smbfs supports them. If
8 you get mount failures, check your kernel log for errors on
9 unknown options.</p><p><span><strong class="command">smbmount</strong></span> is a daemon. After mounting it keeps running until
10 the mounted smbfs is umounted. It will log things that happen
11 when in daemon mode using the "machine name" smbmount, so
12 typically this output will end up in <code class="filename">log.smbmount</code>. The <span><strong class="command">
13 smbmount</strong></span> process may also be called mount.smbfs.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p> <span><strong class="command">smbmount</strong></span>
14 calls <a href="smbmnt.8.html"><span class="citerefentry"><span class="refentrytitle">smbmnt</span>(8)</span></a> to do the actual mount. You
15 must make sure that <span><strong class="command">smbmnt</strong></span> is in the path so
16 that it can be found. </p></div></div><div class="refsect1" lang="en"><a name="id2450658"></a><h2>OPTIONS</h2><div class="variablelist"><dl><dt><span class="term">username=<arg></span></dt><dd><p>
17 specifies the username to connect as. If this is not given, then the environment variable <code class="envar"> USER</code>
18 is used. This option can also take the form "user%password" or "user/workgroup" or "user/workgroup%password"
19 to allow the password and workgroup to be specified as part of the username.
20 </p></dd><dt><span class="term">password=<arg></span></dt><dd><p>
21 specifies the SMB password. If this option is not given then the environment
22 variable <code class="literal">PASSWD</code> is used. If it can find no password
23 <span><strong class="command">smbmount</strong></span> will prompt for a passeword, unless the guest option is given.
25 Note that passwords which contain the argument delimiter character (i.e. a comma ',') will failed to be parsed
26 correctly on the command line. However, the same password defined in the PASSWD environment variable or a
27 credentials file (see below) will be read correctly.
28 </p></dd><dt><span class="term">credentials=<filename></span></dt><dd><p>specifies a file that contains a username and/or password.
29 The format of the file is:
30 </p><pre class="programlisting">
31 username = <value>
32 password = <value>
33 </pre><p>This is preferred over having passwords in plaintext in a
34 shared file, such as <code class="filename">/etc/fstab</code>. Be sure to protect any
35 credentials file properly.
36 </p></dd><dt><span class="term">krb</span></dt><dd><p>Use kerberos (Active Directory). </p></dd><dt><span class="term">netbiosname=<arg></span></dt><dd><p>sets the source NetBIOS name. It defaults
37 to the local hostname. </p></dd><dt><span class="term">uid=<arg></span></dt><dd><p>sets the uid that will own all files on
38 the mounted filesystem.
39 It may be specified as either a username or a numeric uid.
40 </p></dd><dt><span class="term">gid=<arg></span></dt><dd><p>sets the gid that will own all files on
41 the mounted filesystem.
42 It may be specified as either a groupname or a numeric
43 gid. </p></dd><dt><span class="term">port=<arg></span></dt><dd><p>sets the remote SMB port number. The default
44 is 445, fallback is 139. </p></dd><dt><span class="term">fmask=<arg></span></dt><dd><p>sets the file mask. This determines the

46 This is not a umask, but the actual permissions for the files.

48 permissions that remote directories have in the local filesystem.
49 This is not a umask, but the actual permissions for the directories.

65 sets how long a directory listing is cached in milliseconds
66 (also affects visibility of file size and date
67 changes). A higher value means that changes on the
68 server take longer to be noticed but it can give
69 better performance on large directories, especially
70 over long distances. Default is 1000ms but something
71 like 10000ms (10 seconds) is probably more reasonable
73 (Note: only kernel 2.4.2 or later)

75 person using the client. This information is used only if the
76 protocol level is high enough to support session-level
77 passwords. The variable can be used to set both username and
78 password by using the format username%password.</p><p>The variable <code class="envar">PASSWD</code> may contain the password of the
79 person using the client. This information is used only if the
80 protocol level is high enough to support session-level
81 passwords.</p><p>The variable <code class="envar">PASSWD_FILE</code> may contain the pathname
82 of a file to read the password from. A single line of input is
83 read and used as the password.</p></div><div class="refsect1" lang="en"><a name="id2451110"></a><h2>OTHER COMMANDS</h2><p>
84 File systems that have been mounted using the <span><strong class="command">smbmount</strong></span>
85 can be unmounted using the <span><strong class="command">smbumount</strong></span> or the UNIX system
86 <span><strong class="command">umount</strong></span> command.
87 </p></div><div class="refsect1" lang="en"><a name="id2450061"></a><h2>BUGS</h2><p>Passwords and other options containing , can not be handled.
88 For passwords an alternative way of passing them is in a credentials
89 file or in the PASSWD environment.</p><p>The credentials file does not handle usernames or passwords with
90 leading space.</p><p>One smbfs bug is important enough to mention here, even if it
91 is a bit misplaced:</p><div class="itemizedlist"><ul type="disc"><li><p>Mounts sometimes stop working. This is usually
92 caused by smbmount terminating. Since smbfs needs smbmount to
93 reconnect when the server disconnects, the mount will eventually go
94 dead. An umount/mount normally fixes this. At least 2 ways to
95 trigger this bug are known.</p></li></ul></div><p>Note that the typical response to a bug report is suggestion
96 to try the latest version first. So please try doing that first,
97 and always include which versions you use of relevant software
98 when reporting bugs (minimum: samba, kernel, distribution)</p></div><div class="refsect1" lang="en"><a name="id2450103"></a><h2>SEE ALSO</h2><p>Documentation/filesystems/smbfs.txt in the linux kernel
99 source tree may contain additional options and information.</p><p>FreeBSD also has a smbfs, but it is not related to smbmount</p><p>For Solaris, HP-UX and others you may want to look at <a href="smbsh.1.html"><span class="citerefentry"><span class="refentrytitle">smbsh</span>(1)</span></a> or at other solutions, such as
100 Sharity or perhaps replacing the SMB server with a NFS server.</p></div><div class="refsect1" lang="en"><a name="id2450133"></a><h2>AUTHOR</h2><p>Volker Lendecke, Andrew Tridgell, Michael H. Warfield
