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

filesystems other than fossil.
casesensitive
By default, filename lookups are done case insen-
sitive to match windows filesystem semantics.
This option disables case insensitive lookups
which can result in a performance improvement, but
might break some applications.
