smbmount


SYNOPSIS

       smbmount {service} {mount-point} [-o options]


DESCRIPTION

       smbmount  mounts  a  Linux  SMB  filesystem.  It  is usually invoked as
       mount.smbfs by the mount(8) command when using the "-t  smbfs"  option.
       This command only works in Linux, and the kernel must support the smbfs
       filesystem.

       Options to smbmount are specified as a comma-separated list of key=val-
       ue  pairs. It is possible to send options other than those listed here,
       assuming that smbfs supports them. If you  get  mount  failures,  check
       your kernel log for errors on unknown options.

       smbmount is a daemon. After mounting it keeps running until the mounted
       smbfs is umounted. It will log things that happen when in  daemon  mode
       using the "machine name" smbmount, so typically this output will end up
       in log.smbmount. The  smbmount process may also be called  mount.smbfs.

              Note

               smbmount  calls smbmnt(8) to do the actual mount. You must make
              sure that smbmnt is in the path so that it can be found.


OPTIONS

       username=<arg>
              specifies the username to connect as. If this is not given, then
              the  environment  variable   USER  is used. This option can also
              take the form "user%password" or "user/workgroup" or "user/work-
              group%password" to allow the password and workgroup to be speci-
              fied as part of the username.

       password=<arg>
              specifies the SMB password. If this option is not given then the
              environment  variablePASSWD  is used. If it can find no password
              smbmount will prompt for a passeword, unless the guest option is
              given.

              Note that passwords which contain the argument delimiter charac-
              ter (i.e. a comma ’,’) will failed to be parsed correctly on the
              command  line.  However, the same password defined in the PASSWD
              environment variable or a credentials file (see below)  will  be
              read correctly.

       credentials=<filename>
              specifies  a  file that contains a username and/or password. The

       krb    Use kerberos (Active Directory).

       netbiosname=<arg>
              sets the source NetBIOS name. It defaults to the local hostname.

       uid=<arg>
              sets  the uid that will own all files on the mounted filesystem.
              It may be specified as either a username or a numeric uid.

       gid=<arg>
              sets the gid that will own all files on the mounted  filesystem.
              It may be specified as either a groupname or a numeric gid.

       port=<arg>
              sets the remote SMB port number. The default is 445, fallback is
              139.

       fmask=<arg>
              sets the file mask. This determines the permissions that  remote
              files have in the local filesystem. This is not a umask, but the
              actual permissions for the files. The default is  based  on  the
              current umask.

       dmask=<arg>
              Sets  the  directory  mask. This determines the permissions that
              remote directories have in the local filesystem. This is  not  a
              umask,  but  the actual permissions for the directories. The de-
              fault is based on the current umask.

       debug=<arg>
              Sets the debug level. This is useful for tracking down SMB  con-
              nection  problems.  A suggested value to start with is 4. If set
              too high there will be a lot of output, possibly hiding the use-
              ful output.

       ip=<arg>
              Sets the destination host or IP address.

       workgroup=<arg>
              Sets the workgroup on the destination

       sockopt=<arg>
              Sets the TCP socket options. See the smb.conf(5)  socket options
              option.


       rw     mount read-write

       iocharset=<arg>
              sets the charset used by the Linux side for codepage to  charset
              translations  (NLS).  Argument  should be the name of a charset,
              like iso8859-1. (Note: only kernel 2.4.0 or later)

       codepage=<arg>
              sets the codepage the server uses. See the iocharset option. Ex-
              ample value cp850. (Note: only kernel 2.4.0 or later)

       ttl=<arg>
              sets how long a directory listing is cached in milliseconds (al-
              so affects visibility of file size and date changes).  A  higher
              value means that changes on the server take longer to be noticed
              but it can give better performance on large  directories,  espe-
              cially over long distances. Default is 1000ms but something like
              10000ms (10 seconds) is probably more reasonable in many  cases.
              (Note: only kernel 2.4.2 or later)


ENVIRONMENT VARIABLES

       The  variable  USER  may  contain  the username of the person using the
       client. This information is used only if the  protocol  level  is  high
       enough  to support session-level passwords. The variable can be used to
       set both username and password by using the format username%password.

       The variable PASSWD may contain the password of the  person  using  the
       client.  This  information  is  used only if the protocol level is high
       enough to support session-level passwords.

       The variable PASSWD_FILE may contain the pathname of a file to read the
       password from. A single line of input is read and used as the password.


BUGS

       Passwords and other options containing , can not be handled. For  pass-
       words an alternative way of passing them is in a credentials file or in
       the PASSWD environment.

       The credentials file does not handle usernames or passwords with  lead-
       ing space.

       One  smbfs bug is important enough to mention here, even if it is a bit
       misplaced:

       ·  Mounts sometimes stop working. This is usually  caused  by  smbmount


SEE ALSO

       Documentation/filesystems/smbfs.txt in the linux kernel source tree may
       contain additional options and information.

       FreeBSD also has a smbfs, but it is not related to smbmount

       For  Solaris,  HP-UX  and others you may want to look at smbsh(1) or at
       other solutions, such as Sharity or perhaps replacing  the  SMB  server
       with a NFS server.
