I was testing my Android app to see if it could connect to the PH Socket Server. I haven't used the
socket server before--this is the first time. The first time I tried it, it did not work. No surprise
there (at least for me). Programming never works out right the first time for me. So I tried telnet
c:\> telnet localhost 8500
and I pasted in
FORMULA\nAuthorization: Basic TXJHaWJ(secret)lOnN3b2RvZw\nContent-Length: 25\n\nph_macro('AUTO_ARM_STAY')
And I got back
PHSSP/1.0 500 Server Error
Server: PowerHome Socket Server/2.1b
Content-type: text
Content-Length: 139
Request Type FORMULA\nAuthorization: Basic TXJHaWJ(secret)lOnN3b2RvZw\nContent-Length:
25\n\nph_macro('AUTO_ARM_STAY') not supported by server.
I'm using the java class Base64.encode to do the encoding, but since I am not getting an authorization
error, I don't think the problem is with that.
Netstat does show an open TCP port on 8500

I figured out how to make the commands work on telnet. I have to enter each nugget of information and then hit enter
between each piece. "\n" in telnet won't cut it. I should have known that. But it still wouldn't work from my android
client, even when I put each piece of information in it's own println().
I then upgraded to 2.14 which made things worse (see the other thread I started).
Here's the java I was using:
String SocketServerAddress = db.getPhSsServerAddress();
Integer SocketServerPort = db.getPhSsServerPort();
Log.d(MY_DEBUG_TAG, "Setting up Socket: " + SocketServerAddress + ":" + SocketServerPort);
Socket s = new Socket(SocketServerAddress, SocketServerPort);
OutputStream out = s.getOutputStream();
PrintWriter output = new PrintWriter(out);
String body = db.getActionSocketBody(currentPage, selectedText);
String user = db.getSsUsername();
String pass = db.getSsPassword();
String auth = Base64.encodeToString((user + ":" + pass).getBytes(), Base64.DEFAULT);
output.println(reqType);
output.println("Authorization: Basic " + auth);
output.println("Content-Length: " + body.length());
output.println();
output.println(body);
It's hard to troubleshoot now until I get the kinks worked out from the upgrade, but if anyone sees where the error of
my ways is, I would appreciate it.

I solved it. This code works in case anyone else comes across this:
String SocketServerAddress = db.getPhSsServerAddress();
Integer SocketServerPort = db.getPhSsServerPort();
s = new Socket(SocketServerAddress, SocketServerPort);
Log.d(MY_DEBUG_TAG, "Setting up Socket: " + SocketServerAddress + ":" + SocketServerPort);
DataOutputStream out = new DataOutputStream(s.getOutputStream());
DataInputStream in = new DataInputStream(new BufferedInputStream(s.getInputStream()));
Log.d(MY_DEBUG_TAG, "Connected to: " + s.getInetAddress() + " on port " + s.getPort());
String body = db.getActionSocketBody(currentPage, selectedText);
String user = db.getSsUsername();
String pass = db.getSsPassword();
String auth = Base64.encodeToString((user + ":" + pass).getBytes(), Base64.DEFAULT);
String command = reqType + "\nAuthorization: Basic " + auth + "Content-Length: " + body.length() + "\n\n" + body + "\n\n";
Log.d(MY_DEBUG_TAG, "SocketServerCommand: " + command);
out.write(command.getBytes());
out.flush();
Log.d(MY_DEBUG_TAG, "Bytes written: " + out.size());
String st = in.readLine();
Log.d(MY_DEBUG_TAG, "SocketServerResponse: " + st);
Next question:
Are there any other authentication types other than Basic? Base64 isn't what I would call secure.
Finally, Dave, it would be nice if there was an option to log socket server comms.

Skip,
Great work!! I hadnt had a chance to really look into
this but have been following your posts. Glad you were
able to get it worked out.
Socket server security is next on my list after upping
the webserver security. I will probably do something
similar to the webserver cookies but am open to
suggestions. Base64 is definitely weak.
I remember not logging the socket server on purpose due
to the load of transactions going into the database (at
least in my system since I use it extensively and the
remote clients use this as their comm mechanism). I can
add it though and a user can choose whether to log the
info or not. Or perhaps logging to a text file would be
preferred. Im open to suggestions to what would be best.
Dave.

I am not a security expert, but it looks like the different implementations of AES are
considered to be the strongest and most widely ported to different platforms. In java it seems
to be pretty simple to encrypt/decrypt. Same for php. I don't know anything about PowerBuilder,
but I am sure it could be figured out. Of course you will need to encrypt the username/password
pair, and the actual traffic.
While I was setting up the socket server and especially while I was having problems, I longed
for a way of seeing if PH was receiving my messages. I was just about to fire up wire shark
when someone posted an answer to my question on Stack Overflow which solved everything. Anyway,
if it was an option, it would be nice.

How do we use the FORMULATRIGGER and TRIGGER1 - TRIGGER5 commands? What goes in the data field and
what happens when the a message like that is received?

I am NO java expert but I needed to send some info to
PH and I tried below and it worked. in above Skip
example may be because of board missing \n and did not
work for me.I verified with wireshark what is being
sent. any way mine is from command line.
what you need is to install SDK java so you have
access to java.exe and javac.exe and library. (you can
search and find how to install and check Sample
helloworld to check it is working.)
this is just for information for others, code is not
optimize and not using command line parameters. ip and
other information is example and changed for obvious
reason.
---------------------------------
import java.io.*;
import java.net.*;
import java.util.Base64;
import java.util.UUID;
public class PHClient {
public static void main(String[] args) throws
IOException {
String SocketServerAddress ="192.168.0.119";
Integer SocketServerPort =9500;
String body = "ph_macro('LED_ON_OFF')";
String user = "abcdefgh";
String pass = "ABCDEFGH";
String reqType = "FORMULA";
try {
Socket s = new Socket(SocketServerAddress,
SocketServerPort);
System.out.println("Setting up Socket: " +
SocketServerAddress + ":" + SocketServerPort);
DataOutputStream out = new
DataOutputStream(s.getOutputStream());
BufferedReader in = new BufferedReader(new
InputStreamReader(s.getInputStream()));
System.out.println("Connected to: " +
s.getInetAddress() + " on port " + s.getPort());
String auth =
Base64.getEncoder().encodeToString((user+":"+pass).get
Bytes("utf-8"));
String command = reqType + "\nAuthorization: Basic " +
auth + "\nContent-Length: " + body.length() + "\n\n" +
body + "\n";
System.out.println("SocketServerCommand: " + command);
out.write(command.getBytes());
out.flush();
System.out.println("Bytes written: " + out.size());
String st = in.readLine();
System.out.println("SocketServerResponse: " + st);
}
catch (IOException e) {
System.err.println("Couldn't get I/O
for
the connection to " );
System.exit(1);
}
}
}
---------------------------------------------
I am sending info to run one of the macro here is
example of compiling and running.
C:\java>javac PHClient.java
C:\java>java PHClient
Setting up Socket: 192.168.0.119:9500
Connected to: /192.168.0.119 on port 9500
SocketServerCommand: FORMULA
Authorization: Basic ABCDabce12345678fhgdhsjk12xxxa==
Content-Length: 22
ph_macro('LED_ON_OFF')
Bytes written: 105
SocketServerResponse: PHSSP/1.0 200 OK
C:\java>
