smbmount mounts a SMB filesystem. It
is usually invoked as mount.smb from
the mount(8) command when using the
"-t smb" option. The kernel must support the smbfs filesystem.
Options to smbmount are specified as a comma-separated
list of key=value 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/workgroup%password" to allow the password and workgroup
to be specified as part of the username.
password=<arg>
specifies the SMB password. If this
option is not given then the environment variable
PASSWD is used. If it can find
no password smbmount will prompt
for a passeword, unless the guest option is
given.
Note that password which contain the arguement delimiter
character (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 format of the file is:
username = <value>
password = <value>
This is preferred over having passwords in plaintext in a
shared file, such as /etc/fstab. Be sure to protect any
credentials file properly.
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 139.
fmask=<arg>
sets the file mask. This determines the
permissions that remote files have in the local filesystem.
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.
The default is based on the current umask.
debug=<arg>
sets the debug level. This is useful for
tracking down SMB connection problems.
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
socket options option.
scope=<arg>
sets the NetBIOS scope
guest
don't prompt for a password
ro
mount read-only
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. Example value cp850. (Note: only kernel 2.4.0
or later)
ttl=<arg>
how long a directory listing is cached in milliseconds
(also 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, especially
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
Not many known smbmount bugs. But one smbfs bug is
important enough to mention here anyway:
bu
Mounts sometimes stop working. This is usually
caused by smbmount terminating. Since smbfs needs smbmount to
reconnect when the server disconnects, the mount will go
dead. A re-mount normally fixes this. At least 2 ways to
trigger this bug are known.
Note that the typical response to a bug report is suggestion
to try the latest version first. So please try doing that first,
and always include which versions you use of relevant software
when reporting bugs (minimum: samba, kernel, distribution)
