DESCRIPTION
This tool is part of the samba
7 suite.
smbcontrol is a very small program, which
sends messages to a smbd
8, a nmbd
8, or a winbindd
8 daemon running on the system.
OPTIONS
-t|--timeout
Set timeout to seconds.
destination
One of nmbd,
smbd, winbindd
or a process ID.
The all destination causes the
message to "broadcast" to all running daemons including nmbd and
winbind. This is a change for Samba 3.3, prior to this the
parameter smbd used to do this.
The smbd destination causes the
message to be sent to the smbd daemon specified in the
smbd.pid file.
The nmbd destination causes the
message to be sent to the nmbd daemon specified in the
nmbd.pid file.
The winbindd destination causes the
message to be sent to the winbind daemon specified in the
winbindd.pid file.
If a single process ID is given, the message is sent
to only that process.
message-type
Type of message to send. See
the section MESSAGE-TYPES for details.
parameters
any parameters required for the message-type
&popt.autohelp;
&cmdline.common.samba.client;
MESSAGE-TYPES
Available message types are:
close-share
Order smbd to close the client
connections to the named share. Note that this doesn't affect client
connections to any other shares. This message-type takes an argument of the
share name for which client connections will be closed, or the
"*" character which will close all currently open shares.
This may be useful if you made changes to the access controls on the share.
This message can only be sent to smbd.
close-denied-share
Behave like close-share,
but don't disconnect users that are still allowed to access
the share. It can safely be sent to all smbds after changing
share access controls. It will only affect users who have been
denied access since having connected initially. This message
can only be sent to smbd.
debug
Set debug level to the value specified by the
parameter. This can be sent to any of the destinations. If this
message is sent to either the smbd or winbindd daemons, the parent
process will rebroadcast the message to all child processes changing
the debug level in each one.
kill-client-ip
Order smbd to close the client connections from a
given IP address. This message-type takes an argument of the IP
address from which client connections will be closed. This message
can only be sent to smbd.
force-election
This message causes the nmbd daemon to
force a new browse master election.
ping
Send specified number of "ping" messages and
wait for the same number of reply "pong" messages. This can be sent to
any of the destinations.
profile
Change profile settings of a daemon, based on the
parameter. The parameter can be "on" to turn on profile stats
collection, "off" to turn off profile stats collection, "count"
to enable only collection of count stats (time stats are
disabled), and "flush" to zero the current profile stats. This can
be sent to any smbd or nmbd destinations.
debuglevel
Request debuglevel of a certain daemon and write it to stdout. This
can be sent to any of the destinations.
profilelevel
Request profilelevel of a certain daemon and write it to stdout.
This can be sent to any smbd or nmbd destinations.
printnotify
Order smbd to send a printer notify message to any Windows NT clients
connected to a printer. This message-type takes the following arguments:
queuepause printername
Send a queue pause change notify
message to the printer specified.
queueresume printername
Send a queue resume change notify
message for the printer specified.
jobpause printername unixjobid
Send a job pause change notify
message for the printer and unix jobid
specified.
jobresume printername unixjobid
Send a job resume change notify
message for the printer and unix jobid
specified.
jobdelete printername unixjobid
Send a job delete change notify
message for the printer and unix jobid
specified.
Note that this message only sends notification that an
event has occurred. It doesn't actually cause the
event to happen.
This message can only be sent to smbd.
dmalloc-mark
Set a mark for dmalloc. Can be sent to both smbd and nmbd. Only available if samba is built with dmalloc support.
dmalloc-log-changed
Dump the pointers that have changed since the mark set by dmalloc-mark.
Can be sent to both smbd and nmbd. Only available if samba is built with dmalloc support.
shutdown
Shut down specified daemon. Can be sent to both smbd and nmbd.
pool-usage
Print a human-readable description of all
talloc(pool) memory usage by the specified daemon/process. Available
for both smbd and nmbd.
ringbuf-log
Fetch and print the ringbuf log. Requires
logging = ringbuf. Available for smbd, winbindd
and nmbd.
drvupgrade
Force clients of printers using specified driver
to update their local version of the driver. Can only be
sent to smbd.
reload-config
Force daemon to reload smb.conf configuration file. Can be sent
to smbd, nmbd, or winbindd.
reload-printers
Force smbd to reload printers. Can only be sent to
smbd.
idmap
Notify about changes of id mapping. Can be sent
to smbd or (not implemented yet) winbindd.
flush [uid|gid]
Flush caches for sid <-> gid and/or sid <-> uid mapping.
delete <ID>
Remove a mapping from cache. The mapping is given by <ID>
which may either be a sid: S-x-..., a gid: "GID number" or a uid: "UID number".
kill <ID>
Remove a mapping from cache. Terminate smbd if
the id is currently in use.
num-children
Query the number of smbd child processes. This
message can only be sent
to smbd.
reload-certs
Instruct the LDAP server of a Samba AD DC to
reload the TLS certificates protecting ldaps:// connections. This
message can only be sent
to ldap_server.

The original Samba software and related utilities
were created by Andrew Tridgell. Samba is now developed
by the Samba Team as an Open Source project similar
to the way the Linux kernel is developed.
