Nested Class Summary

class

TestNetworkScanner.LantronixDevice parsing based on the following c code from Lantronix tech support forums: len = recvfrom(sock, buf, sizeof(buf), 0, (struct sockaddr *)&from, &fromLen); if (len > 4) { if (buf[3] != 0xf7) { printf("buf[3]=%x\n", buf[3]); continue; } printf("Type : %02x-%02x (%c%c)\n", buf[8], buf[9], buf[8], buf[9] ); printf("Version : Major.Minor: %d.%d\n", buf[7], buf[6] ); printf("Serial #: %02x-%02x-%02x-%02x\n", buf[20], buf[20+1], buf[20+2], buf[20+3]); printf("MAC : %02x-%02x-%02x-%02x-%02x-%02x\n", buf[24], buf[24+1], buf[24+2], buf[24+3], buf[24+4], buf[24+5]); printf("IP Addr : %s\n", inet_ntoa(from.sin_addr)); } else { printf("erroneous data.\n"); } printf("\n");

Throws:

java.net.UnknownHostException

java.net.SocketException

java.io.IOException

getPBRs

public Photobioreactor[] getPBRs()

Returns:

All of the Photobioreactors that have been found on the network. This method should not be invoked until after running this object in a thread. Example:
NetworkScanner scanner = new NetworkScanner("192.168.0.*");
Thread t = new Thread(scanner);
t.start(); // causes the NetworkScanner to scan the network for PBRs
t.join();// wait until scanner is done searching the network
pbrarray = scanner.getPBRs();


main

public static void main(java.lang.String[] args)

Parameters:

args - the command line arguments
