Are there any other places besides the SAM file?
Are LM-Hashes used in any protocols, so they can be found by scanning the network traffic?
If program using lm hashes in network communication without encryption. Yes, you can simple found it by sniffing the network traffic.
what you want
if Password in SAM file
then I will recommend to use Backtrack .you can easily find the Hash
using backtrack (as it have many tools) just u have to copy the SAM file and System File from. (windows/System32/config/) to Backtrack And Enjoy (you can find many tutorials easily on google)

I want to know if i can extract data from .dat file imitating the way I do it inside the software.
Commonly, I load the .dat file in the software through "Load Data" option, then is on my interest obtaining 2 files, generated through "Params to ASCII" and "Data to ASCII" options inside the software. Like you see, I obtain 2 ascii files, which are easily read with a text editor.
The concern is that I do it all manually, and there are lot of .dat files, so I spend lot of ass-hours doing just clicks.
So, I want to know if there is some way to automatize those operations, anyway serve. I am thinking, through my limited knowledge, in scripts that imitate what I do manually (don't know how to do it), or something more complex, which involves reverse-engineering (also don't know how to do it or if it's possible). Or maybe using powershell...
Maybe you guys could help me, surely you have more brillaint minds!
Kind regards!
There are at least four options that I can think of. Sadly, .dat is not a well-defined file format like .pdf, but a general extension used for all kinds of data files. Do you know the name of the software you open the files? That would help to find a solution. Anyway, some general ideas; to recommend any or be more practical requires to know the software.
Use application vendor's API or libraries to read the file. Vendors often provide .Net library for reading the file from disk or via API call. This would be the clean and supported way. For example, to read dBase database files, there's a library at Github.
Read the file as raw binary (as explained in the article linked by Abraham Zinala). I'd rather not try this first, as it requires some reverse engineering and might provide unexpected errors.
Use UI automation. That is, create a script that uses SendKeys to simulate pressing keyboard keys. There are tools such as AutoIT that make this easier. This is kind of last resort, as it is error prone and cumbersome. If the software supports macros or has internal automation capability, try that before 3rd party tools.
The system sending you .dat files offers the data in some other easy to process format. Whilst this is the easiest solution for you, the other party might not agree.
im a university student and I've been tasked with creating a simple File Transfer Protocol using TCP between two machines.
I have very basic knowledge about sockets, and I've been using Linux for a bit. Is it possible to create two virtual machines on VirtualBox (linux machines) and have one be the server and the other be the client? Is that the right way to go about it?
Another question I have is for protocol specification. Is this something I specify in the client or server program or in a separate program?
Other than that, I would appreciate any useful resources or examples you can provide me as a starting point, as it's taking me a lot longer than I thought to really understand how to accomplish this through resources I currrently have. I apologize to any of you who feel this is an unproductive post but I am simply seeking any advice I can get from you more experienced programmers out there.
Thanks!
Is it possible to create two virtual machines on VirtualBox (linux
machines) and have one be the server and the other be the client? Is
that the right way to go about it?
You can do that, but to start with you might find it simpler to run the client and server programs both on the same host. There is no requirement that they must run on separate machines (virtual or otherwise).
Another question I have is for protocol specification. Is this
something I specify in the client or server program or in a separate
program?
The protocol specification is part of the documentation; it's not part of either program. Both programs will have to follow the specification in order to interoperate with each other properly, of course.
Other than that, I would appreciate any useful resources or examples you can provide me as a starting point,
Pointers to resources/examples are off-topic for StackOverflow, but you can google e.g. "TCP programming tutorial" or "TCP programming FAQ" or similar and you should find lots of content.
We are thinking about writing a softphone app. It would basically be a component of a system that has calls queued up from a database. It would interface with a LINUX server which has Asterisk installed.
My first question is
Whether we should write the softphone at all or just buy one?
Secondly, if we do,
what base libraries should be use?
I see SIP Sorcery on CodePlex. More than anything, I am looking for a sense of direction here. Any comments or recommendations would be appreciated.
The answer would depend on the capabilities you have in your team and the place you see your core value and the essence of the service you provide.
In most cases, I'd guess that you don't really care about SIP or doing anything fancy with it that require access to its low level. In such a case, I'd recommend getting a ready-made softphone - either a commercial one or an open source one. I'd go for a commercial one, as it will give you the peace of mind as to its stability and assistance with bug fixing and stuff.
To directly answer your question, one of the many open source softphones are likely to fit your needs, and allow slight modifications as needed. Under most open source licenses there is no obligation to distribute your code as long as you only use it internally (do not distribute the binary.)
Trying to guess what you are trying to do, it sounds like a call center like scenario, so one of the many call queue implementations out there might fit your needs.
I had to write an own softphone and I found a great guide how to achieve it. In the guide there are 10 steps provided for having an own softphone (voip-sip-sdk.com on page 272)
I found it useful and maybe you will find it as well.
i have two machines running MATLAB and i need to exchange information(numbers,images) between them,is there a way in MATLAB i can do it?
If you have Parallel Computing Toolbox and MATLAB Distributed Computing Server, you can use MPI-style programming to send data between the two MATLAB processes. You can use functions like labSend and labReceive to send and receive data.
There are several possibilities without any extra toolboxes, depending on your specific needs. Check the Matlab help about external interfaces for details. For high performance, mexing a custom C communication is probably your best option. Using shared files on a network storage would be an alternative that is easier to implement but less effective, especially if you need frequent communication.
for an example of socket programming in MATLAB using Java, see this related post
Adding some specifics to other answers, here's an example of using Java for sockets. multicore and MatlabMPI use the filesystem, so I believe if you have a shared network filesystem you could use them across machines. And here is an old implementation in C++.
We have direct experience only with multicore, which is the least like real socket communication out of the above, but it gets the job done for coarsely parallel jobs.
Are there any network diagnostics tools available that I can use to measure things like bandwidth.
As such there are a lot of tools which can do this, but I need one that I can embed in my application and program. Environment is WinCE but please list any generic tools also, preferably open source.
Winpcap is a netwok packet capture library for windows which i believe is a port of a *nix library. It is (or was, at one point) used by the network traffic anlyzer Wireshark (a.k.a. Ethereal)
While I'm not certain if the library would work on WinCE, or whether it directly provides what your looking for, it may serve as a framework for any packet analysis that would need to be done in order to facilitate bandwidth use measurement
