It
2 is usually invoked as <b class="command">mount.smbfs</b> 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 <b class="command">smbmount</b> 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><b class="command">smbmount</b> 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 <tt class="filename">log.smbmount</tt>. The <b class="command">
13 smbmount</b> 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> <b class="command">smbmount</b>
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 <b class="command">smbmnt</b> is in the path so

17 this is not given, then the environment variable <tt class="envar">
18 USER</tt> is used. This option can also take the
19 form "user%password" or "user/workgroup" or
20 "user/workgroup%password" to allow the password and workgroup
21 to be specified as part of the username.</p></dd><dt><span class="term">password=<arg></span></dt><dd><p>specifies the SMB password. If this

25 for a passeword, unless the guest option is
27 Note that passwords which contain the argument delimiter
28 character (i.e. a comma ',') will failed to be parsed correctly
29 on the command line. However, the same password defined
30 in the PASSWD environment variable or a credentials file (see
31 below) will be read correctly.

33 The format of the file is:

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

79 person using the client. This information is used only if the
80 protocol level is high enough to support session-level
81 passwords. The variable can be used to set both username and
82 password by using the format username%password.</p><p>The variable <tt class="envar">PASSWD</tt> may contain the password of the
83 person using the client. This information is used only if the
84 protocol level is high enough to support session-level
85 passwords.</p><p>The variable <tt class="envar">PASSWD_FILE</tt> may contain the pathname
86 of a file to read the password from. A single line of input is
87 read and used as the password.</p></div><div class="refsect1" lang="en"><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"><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
