\title{Random Port}
\usage{
random_port(min_port = 49152, max_port = 65536)
random_open_port(min_port = 49152, max_port = 65536, max_tries = 100)
}
\arguments{
\item{min_port, max_port}{The minimum/maximum value to be generated. The minimum should not
be below 49152 and the maximum should not exceed 65536 (see
details).}
\item{max_tries}{The maximum number of times a random port will be searched for.}
}
\description{
Generate a valid, random TCP port.
}
\details{
By definition, a TCP port is an unsigned short, and so it can not
exceed 65535. Additionally, ports in the range 1024 to 49151 are
(possibly) registered by ICANN for specific uses.
\code{random_port()} will simply generate a valid, non-registered
tcp port. \code{random_unused_port()} will generate a port
that is available for socket connections.
\code{random_open_port()} finds a random port not already bound
to an endpoint.
