I am writing the program in Java and using SNMP4J to query OIDs on particular devices. Within SNMP4J, you must specify the version of the SNMP device when setting up the target.

Create a VPN client in C#
I have been looking at different VPNs, and it seems like they don't have great encryption (like the default Windows XP VPN server). I wanted to see if I could create my own, using C#. But I don't know how to create a client that will intercept all of the packets, and forward them to a VPN server. How can I do it? ...
Create TCP Packet in C#
I'm sending data to an extremely old system via TCP. I need to send 2000 bytes in one packet, and I need it not to be split up (what happens when I write out 2000 bytes via a socket). While, yes, I shouldn't have to care about this at an application level -- I in fact do care about this, because I have no other options on the older syst...

How to throttle network traffic for environment simulation?
Hello! I'm trying to test an application that uses a database connection. What I would like to do is throttling the bandwith to, say, 1 MBit or such to get a better feeling for the application under realistic conditions.

C++ for Wireless Sensor Networks
Similar to: Why are RTOS only coded in C, but: Besides the numerous myths about C++, why is it not used as much as C/nesC (TinyOS) for WSN? Knowing C++ can be used for Simulating Wireless Sensor Networks with OMNeT++ it is hard not to think that it can also be used in real-time embedded systems as C is to accomplish event handling. I ...
What is the best compression library for very small amounts of data (3-4 kib?)
I am working on a game engine which is loosely descended from Quake 2, adding some things like scripted effects (allowing the server to specify special effects in detail to a client, instead of having only a limited number of hardcoded effects which the client is capable of.) This is a tradeoff of network efficiency for flexibility. I'v...

Hi all, I'm using a foreach loop to query remote PCs, for some reason querying a certain PCs the program sticks on the PC (maybe it's been turned off mid query), how can I wait for awhile (although a fixed length of time would be no good as some can take minutes to query others 30 mins) and then move on to the next PC? foreach (String ...
Pairing 3 or more iPhone with bonjour
Hi All, I'm working in a game and one of its features is to let the user play with players near him. I know that if I show a dialog to the user for choosing between to be a server or a client it's easy to pair 2 or more devices. However, I think I can do a little better work if I don't show the dialog to the user (most of them don't kn...

Is it safe to use boost serialization to serialize objects in C++ to a binary format for use over a socket?
I know that you can use boost serialization to serialize to a text format and then push over a socket, but I'd like to serialize a class of statistics data into a binary format (both for size and encoding/decoding overhead reasons). Is it safe to use boost serialization for this? My specific worries are: Differences between intege...

I need to keep a large number of Windows XP machines running the same version of python, with an assortment of modules, one of which is python-win32.
