unixctl.man

.IP "\fB\-\-unixctl=\fIsocket\fR"
Sets the name of the control socket on which \fB\*(PN\fR listens for
runtime management commands (see \fBRUNTIME MANAGEMENT COMMANDS\fR,
below).  If \fIsocket\fR does not begin with \fB/\fR, it is
interpreted as relative to \fB@RUNDIR@\fR.  If \fB\-\-unixctl\fR is
not used at all, the default socket is
\fB@RUNDIR@/\*(PN.\fIpid\fB.ctl\fR, where \fIpid\fR is \fB\*(PN\fR's
process ID.
.IP
On Windows, uses a kernel chosen TCP port on the localhost to listen
for runtime management commands.  The kernel chosen TCP port value is written
in a file whose absolute path is pointed by \fIsocket\fR. If \fB\-\-unixctl\fR
is not used at all, the file is created as \fB\*(PN.ctl\fR in the configured
\fIOVS_RUNDIR\fR directory.
.IP
Specifying \fBnone\fR for \fIsocket\fR disables the control socket
feature.
