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

                 Key: NET-238
                 URL: https://issues.apache.org/jira/browse/NET-238
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 2.0
         Environment: Linux x86_64, Eclipse 3.4, commons-net-2.0
            Reporter: jieryn


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??
