[NET-238] RCommandClient wrongly attempts to use local socket with priviledged port (specifically >511 && <1024)

Description

I see a few instances of this around:

int localPort;

localPort = MAX_CLIENT_PORT;

for (localPort = MAX_CLIENT_PORT; localPort >= MIN_CLIENT_PORT; --localPort)
{
try

{ _socket_ = _socketFactory_.createSocket(host, port, localAddr, localPort); }

catch (SocketException e)

{ continue; }

break;
}

if (localPort < MIN_CLIENT_PORT)
throw new BindException("All ports in use or insufficient permssion.");

Yet, this seems to be an error. I can manually issue the rlogin command on my shell and everything just works. After doing it directly from my shell, a netstat -a reveals that I'm using an unpriviledged port on my client side.... why is RCommandClient attempting to use a priviledged port??
