• Is there a secure p2p distributed database?

  - by p2pgirl

  I'm looking for a distributed hash table to store and retrieve values securely. These are my requirements: It must use an existing popular p2p network (I must guarantee my key/value will be stored and kept in multiple peers). None but myself should be able to edit or delete the key/value. Ideally an encryption key that only I have access to would be required to edit my key value. All peers would be able to read the key value (read-only access, only the key holder would be able to edit the value) Is there such p2p distributed hash table? Would the bittorrent distributed hash table meet my requirements?' Where could I find documentation?

• need for tcp fine-tuning on heavily used proxy server

  - by Vijay Gharge

  Hi all, I am using squid like Internet proxy server on RHEL 4 update 6 & 8 with quite heavy load i.e. 8k established connections during peak hour. Without depending much on application provider's expertise I want to achieve maximum o/p from linux. W.r.t. that I have certain questions as following: How to find out if there is scope for further tcp fine-tuning (without exhausting available resources) as the benchmark values given by vendor looks poor! Is there any parameter value that is available from OS / network stack that will show me the results. If at all there is scope, how shall I identify & configure OS tcp stack parameters i.e. using sysctl or any specific parameter Post tuning how shall I clearly measure performance enhancement / degradation ?

• Including the functionality of a tool within another program?

  - by darren

  Hi there I would like to write an application, for my own interest, that graphically visualizes some network concepts. Basically I would like to show the output from tools like ping, traceroute and nmap. The most obvious approach seems to be to use pipes to call out to these tools from my C program, and process the information they return. However, I would like to avoid this heavy-handed approach if possible. My question is, is it possible to somehow link against these tools, or are there APIs that can be used to gain programatic access instead? If so, is this behavior available on a tool-by-tool basis only? One reason for wanting to do this is to keep everything in a single process / address space and to avoid dependance on these external tools. For example, if I wrote an iphone application, I would not be able to spawn processes to call out to the external tools themselves. Thanks for any advice or suggestions.

• Howto read system informations in C++ on windows and linux?

  - by f4

  I need to read system information like cpu/ram/disks usage in C++. Maybe swap, network and process too but that's less important. It has probably been done thousand of times before so I first tried to search for a library. Someone here suggested SIGAR, which seems to fit my needs but is GPL and it is for inclusion in a proprietary product. So it's not an option here. I feel like it's something not that easy to implement, as it'll need testing on several platforms. So a library would be welcome. If you don't know of any library, could you point me in the right direction for both platforms?

• low latency data link pc to android

  - by steveh

  can anyone recommend a method for low latency bi-directional com link between my pc app and android slave app. the app i have works now via wifi but the latency is too slow (about 300mS), i'm looking to get it down to 10mS or so. the android is acting like a glorified remote control to the game on the pc. the apk displays a low res image and sends button presses back to the game and the round trip need to be quick i'm thinking the only option beside the network, is to connect a usb cable but i don't see a lot of support for that path and not even sure it would be lower latency than wifi any ideas please?

• Easier way to move a project in Eclipse

  - by myplacedk

  My projects changes location, and I need to tell Eclipse this. Today I just delete the project and import it from the new location. But I have a lot of projects, they change location often and the paths a very complicated. I'd like a better way to manage this in Eclipse. For example: J:\iteration234_abc\foo\bar\baz\iffle\dizzle\Project Only the root-folder changes (iteration-number and the idenfier "abc"). After that there are lot of folders. Many folders has tons of subfolders with similar names, which makes finding the folder with GUI time-consuming and very boring. It would be so nice if I could just edit the path. As you may have guessed: The J-drive is a network drive, provided by the source control system. The way to tell source control that I'm working on another itertion, is to continue my work in a different folder. My actual Eclipse workspace normally doesn't contain any projects.

• How to implement thread timeout in J2ME?

  - by lilo

  I am using Connector in J2ME and found that sometimes it take a very long time to send a request, and sometime it may halt the whole process. So I try to put code related to Connector in a thread and try to set timeout to the thread. But I found out that it's very difficult to do this in J2ME because there's no join(long) in J2ME. Is there any way to do this? Or any better way to deal with network connection in J2ME? Thanks a lot in advance.

  - by Collin Peters

  Hello, I write a little Tool in C# with Visual Studio 2008. My Problem: I login to a website by HTTP-webrequest, I get an authentification cookie, thats all ok. Than I make a new HTTP-webrequest and add the cookies from the first request to call the next page where i can see my personal data. I see that the cookies will associated with the second request if I debug it but if I check the network traffic I see that are no Cookies transmitted at the second request. I tried many possibilities to see why i dont work but i found nothing. Does somebody have the same problem or know a solution? (Sorry for bad english)

• Can't access my files in ASP.NET web site

  - by jumbojs

  I'm having a very difficult time. I am running windows 2008 server, I have an Able Commerce site using ASP.NET with C#. I'm writing an automated task that will ftp some xml files down into a local directory on our web server and then the program parses the xml file and saves information to our database. The problem, once I save the files to our local directory, my program has no access to the files. The NETWORK SERVICE user permissions isn't being inherited by the xml files so my program can't do anything with them. I can manually change the permissions, but this wouldn't be automated and won't work. How can I get this to work? help please, it's very frustrating.

• Make errors - can the gcc compiler warnings prevent a C file from being compiled into an object file

  - by Xolstice

  I'm trying to compile a wireless network card driver for my Linux box and I ran into a problem with the Make command. During the compilation process I normally see warnings on some of the C files that being are compiled; despite the warnings these files were still able to be compiled to an object file. When the Make process comes to a file called rtmp_wext.c however, the compiler generates a large number of warnings and then the whole Make process stops and returns an exit status of error 1, i.e. make: *** [rtmp_wext.o] Error 1. Usually I see an error with the C file for compilation to halt. This is the first time where it seems compiler warnings are preventing the file from being turned into an object file; is this possible or is something else the cause for the unsuccessful compilation?

• ssh via putty using hostname in opensuse

  - by Ashutosh

  Hi All, I am using opensuse 11.3 and it is connected to DHCP network. I am using putty to connect top machine from window with command: putty -ssh user@ip-address (it works fine) but when trying to connect using hostname it fails to resolve: putty -ssh user@ Every time I want to connect to machine i need to check its ip first and then connect via putty, but when want to connect using hostname it fails and says not able to resolve. Is there a way around so that i can use a common hostname for Linux machine without worrying about its IP address which changes after every reboot? Thanks for reply. Regards, Ashutosh

• Flex SDK 3.5 - Check file mimetype

  - by Fernando

  Is there a way to get a file's mimetype in Flex SDK 3.5 without using its extension? I need to validate if an uploaded file is of a certain kind. This is for images, or documents (PDF, ODT, etc.) All the solutions I've found are by checking its extension. What if I rename a .odt file as a .jpg? Then I can upload it as an image... I should add, we are using an AIR desktop client and a Java EE server. File checking is solved on the Java side, but the idea is not to go to the server, validate the file so if it's not valid, there's no network traffic at all.

• Dynamic WSDL Location in .NET

  - by wadetandy

  I am building a C# application that is consuming a WSDL that is hosted by a server on our network. When I use the "Add Web Reference" functionality of Visual Studio, it works just fine, saving the ip address of the machine, etc. and the SOAP calls work without any issue. We are now making this entire application portable so that it can be installed in any environment. We would like to place all of our settings in one configuration file, so my question is this: Is it possible to somehow specify the IP address of the machine that is hosting the SOAP service in my configuration file and link everything dynamically at runtime?

• How do I deploy a utility with ocx dependency to a test machine without registering the ocx?

  - by Brandon

  I have a test utility that depends upon an ocx file that is installed/registered on my development machine. We'd like to run this tool on a test machine without polluting the machine with any unnecessary files. Nothing should be installed except the target machine software. Running the tool on a network drive or from a stand-alone directory copied to the test machine would be ideal. But, registering the ocx on the test machine is out of the question. Placing the ocx file in the same directory as the exe doesn't work. No matter what it still gives me this error--"The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem." What else can I try?

• Are there issues with tables using an autonumber as a primary key in a back-end ms access db?

  - by owlie

  I inherited an MS Access database at my office that is heavily used by several people over the network. This causes many issues with data collisions and locks. I want to split the db so that each user has thier own front-end app and maintain the core data on the server. Several of the tables use an autonumber:sequence:long as thier primary key - in researching how to perform the split I've come across several posts that hint this can cause issues when distributing a database but I haven't been able to find anything solid. The issue seems to be that a user can begin a new record and receive the next autonumber but a second user can create a new record within a short interval and receive the same autonumber resulting in an error? Does Jet handle this correctly or are there autonumber issues with a FE/BE database? If it's an unlikely-but-possile occurance I'm sure it will still be much better than what my users are currently experiencing but I'd like to know if there are ways I can minimize such issues. Thanks for your help!

• Can't find netbooted for Kerrighed pxe boot with Ubuntu Lucid Server

  - by Pengin

  I'm following installtion guides for pxe booting and kerrighed. I can't find the package nfsbooted for Ubuntu 10.04. Where did it go? Context: At work I have access to 8 mini-ITX PCs and am trying to build a cluster. My plans include trying Condor, GridGain, Hadoop, and recently Kerrighed has caught my eye. (I reaslise these are all for different kinds of things, I'm just evaluating). Ideally, I'd like to have all the nodes network boot from a single server, since that seems so much easier to manage, plus I can 'borrow' additional PCs for a while without touching their HD. I've been getting on great with Ubuntu Lucid Server (10.04), trying to follow the only guides I can find to get pxe booting (and ultimately kerrighed) to work. This guide is for Ubuntu 8.04 and this one is for Debian. They both refer to a package I can't seem to find, nfsbooted. Has this package been replaced? Am I doing something daft?

• How does my ASP.NET app get the SMTP settings automatically from web.config?

  - by Ryan

  I noticed that we always just are like: SmtpClient mSmtpClient = new SmtpClient(); // Send the mail message mSmtpClient.Send(mMailMessage); And the only place the credentials are set are in web.config: <system.net> <mailSettings> <smtp> <network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/> </smtp> </mailSettings> </system.net> So my question is, how does it automagically get them out?

• Send mail from a Windows script

  - by Jörgen Lundberg

  I would like to send mail from a script on a Windows Server 2003 Standard Edition. I think the server setup is pretty much out of the box. The mail server is an Exchange one, and when you're on the internal network you can use plain old SMTP. I have done it from my machine with Perl, but unfortunately Perl is not available on the server. Is there an easy way of doing this from a .bat-file or any other way that doesn't require installing some additional software? Edit: Thanks for the quick replies. The "blat" thingie would probably work fine but with wscript I don't have to use a separate binary. I didn't see PhiLho's post the first time I edited and selected an answer. No need for me to duplicate the code here. Just save the script to a file, say sendmail.vbs, and then call it from the command prompt like so: wscript sendmail.vbs

• Avoid application becoming unresponsive on download

  - by baron

  Hi I have an application which downloads a file from a network location and then displays that files information. It uses WebClient.DownloadFile to achieve this. The problem is, when the user clicks a button to start the download, the application becomes unresponsive until the file has downloaded. This gives the impression the application may have hung. I would like to seek ideas which would avoid this scenario. Though my solution will need to be 'as quick and cheap as possible' I would be interested in hearing about custom loaders that have been built, or some sort of loading symbol / progress bar / sand time clock thingy : ) Thanks for reading.

• Simple and efficient distribution of C++/Boost source code (amalgamation)

  - by Arrieta

  Hello: My job mostly consists of engineering analysis, but I find myself distributing code more and more frequently among my colleagues. A big pain is that not every user is proficient in the intricacies of compiling source code, and I cannot distribute executables. I've been working with C++ using Boost, and the problem is that I cannot request every sysadmin of every network to install the libraries. Instead, I want to distribute a single source file (or as few as possible) so that the user can g++ source.c -o program. So, the question is: can you pack the Boost libraries with your code, and end up with a single file? I am talking about the Boost libraries which are "headers only" or "templates only". As an inspiration, please look at the distribution of SQlite or the Lemon Parser Generator; the author amalgamates the stuff into a single source file which is trivial to compile. Thank you.

• Real time video stream from camera via server to Iphone

  - by devdevdev

  Hi I want to create an Iphone app that can display real time video from a camera. The intended setup is. Camera connected to Mac Mini delivering real time video to Iphone over local network. The Iphone doesn't need to display high quality or use a high frame rate, but it has to be real time. Max 1 sec delay. I've been searching a lot for a solution, but so far I have not found a resonable one. HTTP Live Stream is not a solution due to the delay. Any suggestions?

• Console-App to get all open files for processes

  - by t.kehl

  Hi I am searching for a console-app (where I can pipe the output to a txt-file) which gives me a list of all current processes and the files which each process has open. The tool should also work when the user doesn't has administrativ-privilegues and it should also give file-path which are located on the network (UNC and absolute/mappings). Is there something like this which I can call from another tool and get the information? I am on a windows system. I have a open filename and need now to get the whole path for the file

• Socket left in TIME_WAIT after file transfer via netcat

  - by com

  Using Copying by NetCat I am trying to copy files throught network by NetCat. From console it work pretty well. First I run listening netcat on the destination machine and after I run sending on source machine. The problem is it's doen't work from script from the source machine: ssh -f user@$desthost 'nc -l 1234 | tar xvf - /dev/null &' #listening on destination host tar cv /tmp/file | nc $desthost 1234 #sending to destination host I saw that after running port 1234 is still was open and status of the socket was TIME_WAIT. If you know what's the problem, please, help me out. And by the way, after copying how can I validate that the content is identical? Thanks! Addendum: I found one very strange thing, the same implementation with screen on destination work works, but not stable, sometimes it doesn't copy a file. ssh user@$desthost screen -dm -S test 'nc -l 1234 | tar xvf - ' #listening on destination host Maybe there is an issue with timeout?
