My friend and I have a wireless robot dog connected to a wifi network which our computer is plugged into. The computer is running an Android emulator and we are trying to send a UDP packet to the wireless robot dog. If the dog receives it, it should start sending UDP packets back. The program we wrote works outside of the emulator, and u...
I'm trying to figure out how to use winsockets to be able to turn my game into a LAN-playable game. I've read some winsockets documentation but I can't figure out how a client can get all the games that were created on LAN. Does it have to try to 'connect' to each IP on LAN, like trying to connect to 192.168.0.1, then 192.168.0.2, etc? ...
Hello everybody. I have a problem that I think might be a java related one. I have a java application I need to emulate multiple hosts. The server/client work fine between "normal" computers. When I use the emulator, I get connection refused when client tries to connect to a server in the emulator, same thing if I try telnet. If I turn...
So, I am looking at different hash functions to use for hashing a 4 tuple ip and port to identify flows. One I came across was ((size_t)(key.src.s_addr) * 59) ^ ((size_t)(key.dst.s_addr)) ^ ((size_t)(key.sport) << 16) ^ ((size_t)(key.dport)) ^ ((size_t)(key.proto)); Now for the world of me, I cannot expla...
Is it possible to view other devices that are on the same network in Python (or any programming language for that matter)? Edit: For clarification, what I'd like to do (just to start out) is to display a list of devices connected and their local IP addresses. So on my router, it'll show the info: family_pc, 192.168.1.2 work_laptop, 192...

I'm having trouble communicating position coordinates to a set of motors I have connected on the network. I can send a string just fine, and receive text back from the motor, but I can't seem to send it an int value. Using NSlog I have determined that the actual value I'm sending is correct, however I suspect my method of sending it via...
I want to plot a 3d graph in matlab By graph I mean in the sense of nodes and edges. I have an adjacency matrix as well as a coordinate matrix for every node. Eventually I would hope to colour these nodes and edges The gplot function is only 2d. The scatter3 function does not allow for edges. Any ideas? ...
Basically my problem is that I need to write a script that automatically creates a VPN service in Mac OS X Snow Leopard that can be used on multiple machines to speed up the process rather than going through system preferences every single time. It is specifically needed to run on 10.6.* because the VPN needs to use the Cisco IPSec proto...

I have implemented connectionDidFailWithError to alert the user of any errors that happen in the network connections like time out, no internet connection etc. It gives me correct notification when no internet connection is available. So do I still need to implement Apple's reachability code? ...

Hey, I am playing about with RTSP in Android, getting it to stream using Media Player. Now I am wanting to test them locally, but finding it incredibly difficult. What I have done is run a local Wowza server and published the RTSP url and I am then entering that URL into the android api demos MediaPlayerDemo.java. However, because it w...
Hi, I'm trying to make a client/server Java App. Both client and server will be running on the same wi-fi network. Server will be running on a specific port that client is aware of. I am planning to send a multicast message from client through the network for that specific port to discover the server. However, I'm not too sure how I c...
I have a core java app running on a computer on my network. Can I attach a debugger (netbeans preferred) to this from another computer on the same network? Please advise how to do this if it is possible, or point me to an article I've had a terrible time googling for it. I don't see why it shouldn't be possible. Thanks ...
I am currently developing an embedded uP based appliance which can be remotely controlled via ethernet from a PC using its own SNMP manager software. I have implemented all the private commands, i.e. using a private community password and under the enterprise tree OID (1.3.6.1.4.1.MY_PEN...etc) So from that point of view the unit is wor...

Revised: Would jQuery be a good way to do the following? I'd like to display MRTG traffic graphs for a dozen WAN links on a wide screen for our help desk, highlighting a graph when utilization exceeds a % threshold. A yellow frame might appear and pulse slowly, turning red and pulsing faster at a higher threshold. Not sure whether to ...
