Unable to change presence status of my user with Smack - xmpp

I tried to set online mode but it doesn't work through a Roster. I ran this code and check my localhost server, the mode still "available" and not "Do not disturb".
final Connection connection = new XMPPConnection("xxx.xxx.x.xx");
connection.connect();
connection.login("hieugioi#hieund", "123456");
final Roster roster = connection.getRoster();
Presence p = roster.getPresence("hieugioi#hieund");
p.setPriority(128);
p.setMode(Mode.dnd);

Because you don't send the Presence packet to the server. After you have assembled your Presence packet you need to send it. For example:
Presence p = new Presence(available, "I am busy", 42, Mode.dnd);
connection.sendStanza(p);

connection established but unable to send and receive message to server using Socket Programming in windows phone 8

I read a lot on web but could not successfully send and receive message while connection established correctly using socket programming. one of the simple code is following, Actually, my task is: I have to make connection with server as I have IP and port and I have to send specific message to server; based on this message, server will reply. I want to know how to do it and in what sequence ?
I also tried some other codes in which SocketSreamListener used but its event never raised. I also want to know if I use this listener.BindServiceNameAsync("?") then what should I pass into it and what are ports for windows phone on which I should listen etc
var socket = new StreamSocket();
var writer = new DataWriter(socket.OutputStream);
var reader = new DataReader(socket.InputStream);
await socket.ConnectAsync(new HostName("server ip"), "port")
writer.WriteString("specific msg");
await writer.StoreAsync();
var bytesRead = await reader.LoadAsync(300000);
var response = reader.ReadString(bytesRead);
I will be very thankful as I am stuck and could not get help. I am also unable to debug above code because when I reach reader.LoadAsync then control never returns to next line, I waited alot

Get TCP address information in ZeroMQ

I want to connect clients to a server using ZeroMQ (java bindings, jzmq), but I need the TCP information badly, for example the TCP/IP address of a client request! The problem is, for being able to announce a service in the network I need to grab the TCP address of a request to be able to redirect clients to that service. The broker is a central "service registry" in that case. However, having ZeroMQ services on both sides, I do not see an option to retrieve that information.
What I do now, is to establish a dummy connection using a standard socket to the broker, after the connection is established I grab the IP address used for this connection and close the connection again. The IP address which has been retrieved is now being used for binding on it using a ZeroMQ socket on a random port.
I think this solution is the ugliest solution ever possible, so: What is a better solution to this problem?
Greetings.
0MQ doesn't provide the address of peers, for a number of reasons. It's also not that useful since what you really want is the endpoint to receive connections on, not the address the connection was made on.
What I usually do, and it's elegant enough, is pass bind a service to an ephemeral port, get a full connection endpoint ("tcp://ipaddress:port") and send that string in some way, either broadcast to peers, to a central registry, etc. along with my service name. Then, peers who want to connect back can take the service name, look up to find my endpoint, and connect back to me.
In ZMQ 4.x, you may get the string property "Peer-Address" or the "Identity" property. http://api.zeromq.org/4-2:zmq-msg-gets
The Identity is set in the other peer before connect(). http://api.zeromq.org/4-2:zmq-setsockopt#toc20
For example,
const char *identityString = "identity";
zmq::context_t context(1);
zmq::socket_t socket(context, ZMQ_REQ);
socket.setsockopt(ZMQ_IDENTITY, identityString, strlen(identityString));
socket.connect("tcp://127.0.0.1:5555");
Then the other side:
while(1)
{
zmq::message_t request;
if (socket.recv(&request, ZMQ_NOBLOCK))
{
const char* identity = request.gets("Identity");
const char* peerAddress = request.gets("Peer-Address");
printf("Received from %s %s\n", peerAddress, identity);
break;
}
}
I'm using CppZmq btw, you should be able to find the relevant calls easily.
Digging deeper into the libzmq code, I discovered that the library attaches to every message instance the file descriptor that it was received on.
This worked for me
int sockfd = zmq_msg_get(&msg, ZMQ_SRCFD);
sockaddr_in addr;
socklen_t asize = sizeof(addr);
getpeername(sockfd, (sockaddr*)&addr, &asize);
std::cout << inet_ntoa(addr.sin_addr) << ":" << addr.sin_port << std::endl;
Note that the FDs can and will be reused by other connections.
I'm working with version 4.2.1 of the api using the CZMQ binding and I found a solution for my case (ZMQ_STREAM). It works by setting an id before connecting.
The relevant socket option is "ZMQ_CONNECT_RID".
ZMQ api via zmq_setsockopt()
CZMQ api via zsock_set_connect_rid()
Some codes with redacted redacted ips.
const char endpoint1[] = "tcp://1.2.3.4:12345"
const char endpoint2[] = "tcp://5.6.7.8:12345"
zsock_t *stream = zsock_new(ZMQ_STREAM);
zsock_set_connect_rid(stream, endpoint1);
zsock_connect(stream, endpoint1);
zsock_set_connect_rid(stream, endpoint2);
zsock_connect(stream, endpoint2);
Then I get those 2 messages if there is a connection. First frame is the id and second frame is empty on connect/disconnect for ZMQ_STREAM sockets.
[Message1]
[019] tcp://1.2.3.4:12345
[000]
[Message2]
[019] tcp://5.6.7.8:12345
[000]
Another option is to use the zmq_socket_monitor() or czmq zmonitor. It was one of my first solution but I was looking for something lighter. I was able the get the endpoint that way without setting the id directly on the socket.
The zmonitor zactor make it possible to subscribe to socket events and then it sends a message with 3 frames:
[009] CONNECTED
[002] 14
[021] tcp://127.0.0.1:33445

Delayed receiving the email message using the SMTP server

I already deployed the Email Service I developed on the Chicago Server. Last Friday 11:30pm in Philippine time, I tested the sending and it run's properly, but when I checked my email there's no message in inbox or spam. And then, Saturday 1:30am, I've noticed that I received the message that I tested last Friday.
Please advice me guys! thanks!
My Questions is:
a.) Do I need to configure something on the Server to make the real time receiving on emails?
here's my code:
//send email
MailMessage objEmail = new MailMessage(new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()), new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()));
objEmail.Subject = "Test";
objEmail.Body = "CODE:" + _Message;
objEmail.Priority = MailPriority.High;
SmtpClient SmtpMail = new SmtpClient();
SmtpMail.Host = "localhost";
SmtpMail.Send(objEmail);
Put this one on your code:
SmtpMail.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
And also, configure the relay restrictions on the SMTP server that will allow your 120.0.0.1/localhost..
Last, configure the firewall and port forwarding on the server.
I hope this will help you..

Python APNs does not process request

I'm trying to implement a server side script for sending push notifications to apple push notification server. I create the ssl connection, I send the payload - but am unable to get a response from the APNs. Here is my code:
import socket, ssl, pprint, struct, time, binascii
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# require a certificate from the server
ssl_sock = ssl.wrap_socket( s,
keyfile="/Users/Jeff/Desktop/pickmeup-key2-noenc.pem",
certfile="/Users/Jeff/Desktop/pickmeup-cert2.pem",
server_side=False,
do_handshake_on_connect=True,
cert_reqs=ssl.CERT_REQUIRED,
ca_certs="/Users/Jeff/Desktop/entrustrootcert.pem",)
#ciphers="ALL")
ssl_sock.connect(('gateway.sandbox.push.apple.com', 2195))
print repr(ssl_sock.getpeername())
print ssl_sock.cipher()
print pprint.pformat(ssl_sock.getpeercert())
command = '\x00'
identifier = 1987
expiry = time.time()
deviceToken = "9858d81caa236a86cc67d01e1a07ba1df0982178dd7c95aae115d033b93cb3f5"
alert = "This is a test message"
sound = "UILocalNotificationDefaultSoundName"
payload = "{\"aps\":{\"alert\":\"%s\",\"sound\":\"%s\"}}" %(alert, sound)
packetFormat = "!cIIH%dsH%ds" %(32, len(payload))
packet = struct.pack(packetFormat,
command,
identifier,
int(expiry),
32,
binascii.unhexlify(deviceToken),
len(payload),
payload)
nBytesWritten = ssl_sock.write(packet)
print "nBytesWritten = %d" %(nBytesWritten)
data = ssl_sock.read(1024)
print len(data)
ssl_sock.close()
Running this script, I generate the following output:
('17.149.34.132', 2195)
('AES256-SHA', 'TLSv1/SSLv3', 256)
{'notAfter': 'May 31 00:04:27 2012 GMT',
'subject': ((('countryName', u'US'),),
(('stateOrProvinceName', u'California'),),
(('localityName', u'Cupertino'),),
(('organizationName', u'Apple Inc'),),
(('organizationalUnitName', u'Internet Services'),),
(('commonName', u'gateway.sandbox.push.apple.com'),))}
nBytesWritten = 133
0
Any ideas on what might be going wrong? (I am sending enhanced push notifications so I am expecting a response from apple push notification server)
The key thing to note is that read() is returning no data. In Python, read() is supposed to block until data is available or the connection closes. Apple is closing your connection.
Why? Well, probably because you sent a malformed request. command=0 is a normal push notification; command=1 is enhanced. The big-endian 1987 will be interpreted as a 0-byte device token and a 1987-byte payload, neither of which are valid.
(And FWIW, I'd use B instead of c for the command ID; it seems to make more sense.)
you may consider https://github.com/djacobs/PyAPNs that wrapped lot of useful features, including:
error handling
support enhanced message format and auto resend messages which are sent before error response
non-blocking ssl socket connection with great performance
Apple Push notification server doesn't give a response, it's a one-way binary socket.
Rather than rolling your own solution you could try apns-python-wrapper or apns

Send XMPP (Smack) Message

Ok, the problem should be trivial but I can't get to the bottom of it.
I have two users A & B
Their JID's for this example will be A#123 and B#123 where 123 is the IP of the server.
I'm sending a message from A->B using the following code:
chat = chatmanager.createChat(username,
new MessageListener() {
public void processMessage(Chat chat, Message message) {}});
String sendUsername = username + "#123";
Message msgObj = new Message(sendUsername, Message.Type.chat);
msgObj.setBody(message);
chat.sendMessage(msgObj);
I've hardcoded the IP so that I'm 100% sure that I attach the "#123" at the end of the nickname so there are no incorrect JIDs.
So A#123 sends msgObj to B#123. This is how I understood XMPP messaging to work. That you can't send from A->B but it must be A#123 -> B#123.
However, my server seems to think otherwise. It continuously informs me of the following error:
2010.12.27 19:02:52 [org.jivesoftware.openfire.session.LocalOutgoingServerSession
.createOutgoingSession(LocalOutgoingServerSession.java:258)] Error trying to
connect to remote server: A(DNS lookup: A:5269)
java.net.UnknownHostException: A
In both A and B's roster on the Openfire server, they have each other as a contact with the proper JIDs (username#123).
Can anyone provide some insight? I'm lost.
Edit
I'm trying to use Wireshark to catch the XML sent to and from the Openfire server to determine if the recipient of the message is named properly (A#123 instead of A).
Upon using Wireshark, I received this as the XML being transferred:
\302\3469\223\341\3429\000\000\000\000\377\377
I have disabled SSL, I have connected un-securely. I'm not sure why I'm getting SSL type XML, is that what it is?
Turns out the answer to this problem was something that was just overlooked.
In the first line of code:
chat = chatmanager.createChat(username, new MessageListener() {
public void processMessage(Chat chat, Message message) {}
});
I didn't make the variable "username" have the proper IP extension. So it was merely "A" instead of "A#123"
Moving "sendUsername" to the top and Changing "username" to "sendUsername" makes everything work great :)
Silly mistake.
Using IP addresses is almost always more confusing than you think it is.
There's a good chance you have OpenFire misconfigured, so that the IP address isn't a valid hostname. Go into the admin console, under "System Properties", and make sure that the xmpp.domain property is set to your IP address.
