.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`nbdkit\-random\-plugin\*(C'\fR is a plugin for \fBnbdkit\fR\|(1) which serves
random data, read only.
.PP
The size of the virtual disk must be specified using the \f(CW\*(C`size\*(C'\fR
parameter.  If you specify the \f(CW\*(C`seed\*(C'\fR parameter then you will get the
same random data over multiple runs with the same seed.
.PP
The random data is generated using an \fIinsecure\fR method.  This plugin
is mainly good for testing \s-1NBD\s0 clients.
.SH "PARAMETERS"
.IX Header "PARAMETERS"
.IP "\fBsize=\fR\s-1SIZE\s0" 4
.IX Item "size=SIZE"
Specify the virtual size of the disk image.
.Sp
This parameter is required.
.IP "\fBseed=\fR\s-1SEED\s0" 4
.IX Item "seed=SEED"
Specify the random seed to get repeatable data over multiple runs.
.Sp
If not specified then a random seed is chosen.
