Someone is tracking my iPad/iPhone using NetMaster and GeoTrace apps. They use GeoTrace (so they say) to monitor my text messages. Only portions or sentences (which I don’t recognize) that are supposedly from my iPhone show in saved GeoTrace searches.
He also has many screen shots he took of hops he has traced that supposedly show my internet searches (none of which I recognize.) What does one find out by looking at ‘hops?’
"Hops" refer to the route internet traffic takes from one host to another. On the internet packets are often routed through multiple intermediate hosts to get to their final destination. You could say that a packet "hops" from one host to another giving rise to the term. It doesn't have anything to do with internet searches.
"GeoTrace" looks like just a fancy GUI to the standard traceroute program which does not and cannot monitor text messages. All it does is show the route between you and another host.

I want to have two tcp connection in a single machine via socket programming, But this two connection should connect to two different network interfaces. One is say my 3g dongle and the other is wifi modem. But is it possible for a single machine(OS) to have two connection active at a time? If possible how to program the tcp connection via socket programming?
This can definitely be done, if you just create two programs and run each of them, they will both be able to communicate over their respective network. When you run a program, the operating system creates a process dedicated to running that program, which is assigned time on the CPU by the scheduling algorithm in the OS. So long as your CPU can keep up with any processing associated with the networks, they will both be able to run simultaneously.
You make no mention of your plans for this, but be aware that I/O times can also limit your speeds. If you're using an older computer, it may not be able to transmit a lot of data very quickly due to an out-dated (or just low powered) network card.
Next time try to research your question first, information about this can be found with relative ease using any popular search engine, including the search bar at the top of this page. Also read this, or one of the other several help articles about asking questions well, that are available from the page you had to go through before asking the question.
So, I have read that it is possible to trace the IP of a Facebook friend while talking to him on chat by using Fiddler and Firebug. Now, as far as I am know, Facebook uses HTTPS and all in all, I cannot seem to get anything precise from Fiddler.
May anyone be kind enough to explain if this is really possible and if so, how the process goes?
I dont have a direct answer to your question, but i can give you some guidelines:
If the chat is working as a peer-to-peer network (which i highly doubt) you can trace the incoming tcp/udp connection and search it for the message using a sniffing program (like wireshark) and from there fetch their IP.
If the chat is based on that every message goes through a server (which is probably based on SOMM. not that it matters. (Server Oriented Messaging Model)). now if it is that way there is virtually no way to figure out the IP because the servers are acting as a proxy and masking the original IP, however. if FB includes some sort of meta data (which they do for location for phones etc.) that might contain the sender IP and some other stuff like the mac address etc etc. now i'm not sure of that but its a good place to look.
If you want help with firebug and all those other html/http/browser development tools there are plenty of tutorials out there. If you already know how to use it you might want to check the resources that's loaded when a message is sent. From experience i can tell that when a comment is added to something a whole bunch of crap happens that append stuff to the current html document. but i have never ever seen some meta data through that. anyway it's a good place to start.
I am programming a bot that would emulate different users on one site. If all on the same port I wouldn't know a way to identify which virtual user should receive a data packet. I thought about opening multiple ports on one program, googled it, but I couldn't find information. Is it possible?
Yes, you can open multiple sockets, each listening on a different port.
The question is, do you need it?
If all on the same port I wouldn't know a way to identify which virtual user should receive a data packet.
You can build this into the protocol, for example a message consist of first the identifier of the user (fixed number of bytes), then the size of the message (eg: stored with an int32_t) and then the actual message.
I'm struggling with Kamailio as a simple dispatcher for FreeSwitch. This is my configuration so far: http://pastebin.com/nBPSpe6S
Connecting an iPhone and an Android makes the calls between them timeout.
Connecting one of the phones and my laptops makes calls between them produce the error "Too many hops".
With all of them I'm able to call in to the Freeswitch, for listening to voicemail, hold music etc.
So I guess it's still NAT problems or similar?
Can anyone spot the error, missing thing or something else that is wrong with the config?
P.S. Adding phones, laptops etc. directly to FreeSwitch, without Kamailio, makes everything works.
"Too many hops" is just that - too many hops. A SIP messages is being routed around in a bad way. In many cases in Kamailio, this is because DNS and Kamailio doesn't have the same view of the world. Kamailio doesn't know which domains it's authoritative for (the alias= configuration parameter) and forwards using DNS. DNS points back to the same Kamailio.
Your configuration lacks both alias= and IP addresses kamailio should listen to. Now, your configuration doesn't really use the alias, so I don't see that problem here. Since you are not showing the dispatcher table it's hard to figure out. I suggest you add a couple of calls to xlog() to see what's going on and figure out why a message is looping around. Good luck!
I am developing an iPhone application that allows to basically click through a series of actions. These series are predefined and synced with a common configuration server.
That app might be running on multiple devices at the same time. All devices are assumed to have the same series of actions defined on them. All devices are considered equal, there is not a server and multiple clients or something like that.
(Only) one of these devices is used by a person at any given time, it is however possible that the person switches to a different device at any given time. All "passive" devices need to be synchronized with the active one, so that they display the same action.
The whole thing should happen as automatically as possible. No selection of devices, configuration, all devices in the same network take part in the same series of actions.
One additional requirement is that a device could join during a presentation (a series of actions) and needs to jump to the currently active action.
Right now, I see two options to implement the networking/communication part of that:
Bonjour. I have implemented a working prototype that can automatically connect with one (1) other device in the network and communicate with that. I am not sure at this point how much additional work the "multiple devices" requirement is. Would I have to open a set of connections for every device and manually send the sync events to all of them? Is there a better way or does bonjour provide anything to help me with that? What does Bonjour provide given that I want to communicate with every device in the network anyway?
Multicast with AsyncUdpSocket. Simply define a port and send multicast sync events out to that port. I guess the main issue compared to using bonjour with tcp would be that the connection is not safe and packets could be lost. This is however in a private, protected wlan network with low traffic if that would really be an issue. Are there other disadvantages that I'm not seeing? Because that sounds like a relatively easy option at this point...
Which one would you suggest? Or is there another, better alternative that I'm not thinking of?
You should check out GameKit (built in to iOS)--they have a lot of the machinery you need in a convenient package. You can easily discover peers on the network and easily send data back for forth between clients (broadcast or peer to peer)
In my experience Bonjour is perfect for what you want. There's an excellent tutorial with associated source code: Chatty that can be easily modified to suit your purposes.
I hobbled together a distributed message bus for the iphone (no centralized server) that would work great for this. It should be noted that the UI guy made a mess of the code, so thar' be dragons there: https://code.google.com/p/iphonebusmiddleware/
The basic idea is to use bonjour to form a network with leader election. The leader becomes the hub through which all the slaves subscribe to topics of interest. Then any message sent to a given topic is delivered to every node subscribed to said topic. A master disconnection simple means restarting the leader election process.
