.SH DESCRIPTION
|
|
.I Cifsd
|
|
exports filesystems to
|
|
.SM CIFS or
|
|
.SM SMB
|
|
clients like Microsoft \(tm Windows.
|
|
.PP
|
|
It is normally started by the network listen process via the
|
|
.B /rc/bin/service/tcp445
|
|
service script (see
|
|
.IR listen (8)),
|
|
which passes
|
|
.I conndir
|
|
and filedescriptors 0 and 1 to the incoming connection.
|
|
.PP
|
|
Users are authenticated by their Inferno/pop secret held by the auth server.
|
|
When successful,
|
|
.I cifsd
|
|
changes its user id and namespace to the authenticated user.
|
|
Informative log messages are appended to
|
|
.B /sys/log/cifsd
|
|
if it exists.
|
|
.PP
|
|
By default the share
|
|
.B local
|
|
is offered, which represents the root of the namespace
|
|
described by
|
|
.B /lib/namespace.
|
|
If a different name is explicitly requested by the client then
|
|
.B /bin/9fs
|
|
(see
|
|
.IR srv (4))
|
|
is invoked to attach that filesystem, which is then exported instead.
|
|
.PP
|
|
The flags are:
|
|
.TP
|
|
.B t
|
|
Run the server in trusted mode, so it will not require
|
|
authentication from the client and keep running in the callers
|
|
namespace.
|
|
.TP
|
|
.B d
|
|
Enable or increases debug verbosity for the
|
|
.I debuglog
|
|
file. Debug messages are never written to the system logfile.
|
|
.TP
|
|
.B f
|
|
Specify the filename for the
|
|
.I debuglog
|
|
file. If not specified no debug messages are generated.
|
|
.TP
|
|
.B w
|
|
Set the workgroup (or primary domain) to
|
|
.I name. The default is
|
|
.SM WORKGROUP
|
|
.TP
|
|
.B o
|
|
Enables the following
|
|
.I option
|
|
string.
|
|
This flag can appear multiple times when more than one option has to
|
|
be enabled. Valid options are:
|
|
.RS
|
|
.TP
|
|
.B trspaces
|
|
transforms whitespace in filenames to non breaking whitespace. This is useful
|
|
when exporting filesystems other than fossil.
|
|
.TP
|
|
.B casesensitive
|
|
By default, filename lookups are done case insensitive to match
|
|
windows filesystem semantics. This option disables case insensitive
|
|
lookups which can result in a performance improvement, but might break
|
|
some applications.
