26 <title>DESCRIPTION</title>
28 <para><command>smbmount</command> mounts a Linux SMB filesystem. It
29 is usually invoked as <command>mount.smbfs</command> by
30 the <citerefentry><refentrytitle>mount</refentrytitle>
31 <manvolnum>8</manvolnum></citerefentry> command when using the
32 "-t smbfs" option. This command only works in Linux, and the kernel must
33 support the smbfs filesystem. </para>
35 <para>Options to <command>smbmount</command> are specified as a comma-separated
36 list of key=value pairs. It is possible to send options other
37 than those listed here, assuming that smbfs supports them. If
38 you get mount failures, check your kernel log for errors on
39 unknown options.</para>
41 <para><command>smbmount</command> is a daemon. After mounting it keeps running until
42 the mounted smbfs is umounted. It will log things that happen
43 when in daemon mode using the "machine name" smbmount, so
44 typically this output will end up in <filename>log.smbmount</filename>. The <command>
45 smbmount</command> process may also be called mount.smbfs.</para>
47 <note><para> <command>smbmount</command>
48 calls <citerefentry><refentrytitle>smbmnt</refentrytitle>
49 <manvolnum>8</manvolnum></citerefentry> to do the actual mount. You
50 must make sure that <command>smbmnt</command> is in the path so
51 that it can be found. </para></note>
56 <title>OPTIONS</title>
60 <term>username=<arg></term>
62 specifies the username to connect as. If this is not given, then the environment variable <envar> USER</envar>
63 is used. This option can also take the form "user%password" or "user/workgroup" or "user/workgroup%password"
64 to allow the password and workgroup to be specified as part of the username.
69 <term>password=<arg></term>
71 specifies the SMB password. If this option is not given then the environment
72 variable <literal>PASSWD</literal> is used. If it can find no password
73 <command>smbmount</command> will prompt for a password, unless the guest option is given.
77 Note that passwords which contain the argument delimiter character (i.e. a comma ',') will failed to be parsed
78 correctly on the command line. However, the same password defined in the PASSWD environment variable or a
79 credentials file (see below) will be read correctly.
85 <term>credentials=<filename></term>
86 <listitem><para>specifies a file that contains a username and/or password.
87 The format of the file is:
89 username = <value>
90 password = <value>
91 </programlisting></para>
93 <para>This is preferred over having passwords in plaintext in a
94 shared file, such as <filename>/etc/fstab</filename>. Be sure to protect any
95 credentials file properly.
101 <listitem><para>Use kerberos (Active Directory). </para></listitem>
105 <term>netbiosname=<arg></term>
106 <listitem><para>sets the source NetBIOS name. It defaults
107 to the local hostname. </para></listitem>
111 <term>uid=<arg></term>
112 <listitem><para>sets the uid that will own all files on
113 the mounted filesystem.
114 It may be specified as either a username or a numeric uid.
120 <term>gid=<arg></term>
121 <listitem><para>sets the gid that will own all files on
122 the mounted filesystem.
123 It may be specified as either a groupname or a numeric
124 gid. </para></listitem>
129 <term>port=<arg></term>
130 <listitem><para>sets the remote SMB port number. The default
131 is 445, fallback is 139. </para></listitem>
136 <term>fmask=<arg></term>
137 <listitem><para>sets the file mask. This determines the
138 permissions that remote files have in the local filesystem.
139 This is not a umask, but the actual permissions for the files.
140 The default is based on the current umask. </para></listitem>
145 <term>dmask=<arg></term>
146 <listitem><para>Sets the directory mask. This determines the
147 permissions that remote directories have in the local filesystem.
148 This is not a umask, but the actual permissions for the directories.
149 The default is based on the current umask. </para></listitem>
154 <term>debug=<arg></term>
155 <listitem><para>Sets the debug level. This is useful for
156 tracking down SMB connection problems. A suggested value to
157 start with is 4. If set too high there will be a lot of
158 output, possibly hiding the useful output.</para></listitem>
163 <term>ip=<arg></term>
164 <listitem><para>Sets the destination host or IP address.
171 <term>workgroup=<arg></term>
172 <listitem><para>Sets the workgroup on the destination </para>
178 <term>sockopt=<arg></term>
179 <listitem><para>Sets the TCP socket options. See the <ulink
180 url="smb.conf.5.html#SOCKETOPTIONS"><citerefentry><refentrytitle>smb.conf</refentrytitle>
181 <manvolnum>5</manvolnum></citerefentry></ulink> <parameter>socket options</parameter> option.
187 <term>scope=<arg></term>
188 <listitem><para>Sets the NetBIOS scope </para></listitem>
193 <listitem><para>Don't prompt for a password </para></listitem>
198 <listitem><para>mount read-only </para></listitem>
202 <term>rw</term><listitem><para>mount read-write </para></listitem>
206 <term>iocharset=<arg></term>
208 sets the charset used by the Linux side for codepage
209 to charset translations (NLS). Argument should be the
210 name of a charset, like iso8859-1. (Note: only kernel
216 <term>codepage=<arg></term>
218 sets the codepage the server uses. See the iocharset
219 option. Example value cp850. (Note: only kernel 2.4.0
225 <term>ttl=<arg></term>
227 sets how long a directory listing is cached in milliseconds
228 (also affects visibility of file size and date
229 changes). A higher value means that changes on the
230 server take longer to be noticed but it can give
231 better performance on large directories, especially
232 over long distances. Default is 1000ms but something
233 like 10000ms (10 seconds) is probably more reasonable
235 (Note: only kernel 2.4.2 or later)
245 <title>ENVIRONMENT VARIABLES</title>
247 <para>The variable <envar>USER</envar> may contain the username of the
248 person using the client. This information is used only if the
249 protocol level is high enough to support session-level
250 passwords. The variable can be used to set both username and
251 password by using the format username%password.</para>
253 <para>The variable <envar>PASSWD</envar> may contain the password of the
254 person using the client. This information is used only if the
255 protocol level is high enough to support session-level
258 <para>The variable <envar>PASSWD_FILE</envar> may contain the pathname
259 of a file to read the password from. A single line of input is
260 read and used as the password.</para>
264 <title>OTHER COMMANDS</title>
267 File systems that have been mounted using the <command>smbmount</command>
268 can be unmounted using the <command>smbumount</command> or the UNIX system
269 <command>umount</command> command.
278 <para>Passwords and other options containing , can not be handled.
279 For passwords an alternative way of passing them is in a credentials
280 file or in the PASSWD environment.</para>
282 <para>The credentials file does not handle usernames or passwords with
283 leading space.</para>
285 <para>One smbfs bug is important enough to mention here, even if it
286 is a bit misplaced:</para>
290 <listitem><para>Mounts sometimes stop working. This is usually
291 caused by smbmount terminating. Since smbfs needs smbmount to
292 reconnect when the server disconnects, the mount will eventually go
293 dead. An umount/mount normally fixes this. At least 2 ways to
294 trigger this bug are known.</para></listitem>
298 <para>Note that the typical response to a bug report is suggestion
299 to try the latest version first. So please try doing that first,
300 and always include which versions you use of relevant software
301 when reporting bugs (minimum: samba, kernel, distribution)</para>
307 <title>SEE ALSO</title>
309 <para>Documentation/filesystems/smbfs.txt in the linux kernel
310 source tree may contain additional options and information.</para>
312 <para>FreeBSD also has a smbfs, but it is not related to smbmount</para>
314 <para>For Solaris, HP-UX and others you may want to look at <citerefentry><refentrytitle>smbsh</refentrytitle>
315 <manvolnum>1</manvolnum></citerefentry> or at other solutions, such as
316 Sharity or perhaps replacing the SMB server with a NFS server.</para>
