• Just an experiment changing the application data path

  - by Arthur

  When I change the Appication Data path in windows xp registry to a network folder I get this error message on the next system startup: "windows cannot load the user's profile but has logged you with the default profile system" The registry keys are: "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]" "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]" under the names "AppData" and "Local AppData" I dont care if "Windows logins you with the default profile system" but is there a way to disable that message, or change the message timeout form 30 seconds to 0?,or maybe create an script that changes the Application Data path every system startup? P.S. The computer with the shared folder is always on.

• Entity Framework - Self Tracking Objects - how to reset client side?

  - by David

  I am using wcf with self tracking entity framework objects. On the client side i have bound an entity to an edit form (which has multiple textboxes and comboboxes). After the user hits Save, the entity is sent through wcf to the server wcf service which will attempt to save the entity. If there is a failure (say a network failure), I need to reset the current entity back to original values. How best can I do this client side? (I recognize with Self Tracking objects there is a property OriginalValues however that collection seems to have count=0) so not sure how to get the original values? Thanks-

• C# - Thread does not abort on application closing

  - by michal

  Hi, I have an application which does some background task (network listening & reading) in separate Thread. It seems however that the Thread is not being Terminated/Aborted when I close the application (click "x" button on titlebar ;)). Is that because the main Thread routine is while(true) {...} ? What is the solution here? I was looking for some "interruption" flag for the Thread as the condition for "while" loop, but didn't found any ...

• Which database engines support IP addresses as a native type?

  - by Matt McClellan

  I'm trying to find databases with support for IP addresses as a native type (as opposed to storing as a string, or an unsigned integer, which at least one commenter has already pointed out won't work for IPv6). The primary reason I'm looking for this is ease of development. For example, sorting on a "native" IP address column would be correct (as opposed to when it's stored as a string). I would assume support for such a type would also include useful operations such as determining if an IP address is inside a specified network for use in WHERE clauses. The only one I'm aware of so far is PostgreSQL with its inet class. Does anyone have any others?

• Implementing Transparent Persistence

  - by Jules

  Transparent persistence allows you to use regular objects instead of a database. The objects are automatically read from and written to disk. Examples of such systems are Gemstone and Rucksack (for common lisp). Simplified version of what they do: if you access foo.bar and bar is not in memory, it gets loaded from disk. If you do foo.bar = baz then the foo object gets updated on disk. Most systems also have some form of transactions, and they may have support for sharing objects across programs and even across a network. My question is what are the different techniques for implementing these kind of systems and what are the trade offs between these implementation approaches?

• Best canvas for drawing in wxPython?

  - by Pablo Rodriguez

  I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectional. I would like to capture the clicking events for the nodes and the arches (to select the element and show its properties somewhere), and the dragging events for the nodes (to move them around) and arches (to connect or disconnect elements). I've done some research and I've narrowed the alternatives down to OGL (Object Graphics Library) and FloatCanvas. I would not like to go down to the DrawingContext, but it is not discarded if necessary. Which canvas option would you choose?

• Efficient multiple services exposed over c# .NET remoting using more channels or end points?

  - by wb

  I am using remoting over TCP for a prototype distributed server application where I want to have varying multiple services exposed from each remoting server process. In some cases I want the services running from the same process but I don't want whatever is using the service to care about that. I am wondering is it more efficient to have multiple services in the same process going over the same remoting channel distinguished by endpoint URI/URL or should I be creating new channels on different ports for each service in the same process? Using up ports isn't so much of a problem as the number of services will be low and the network and machine configuration is completely controlled. Also its not clear to me if remoting sends the URI string for every single message or just at connection time, and whether if the remoting framework is intelligent enough to reduce work if calls are made on the same machine and even the same process? Thanks in advance.

• How to reduce the number of cert validation requests... (IE is killing me slowly)

  - by scooterhanson

  On a customer's internal network, I can make a request to my SSL site using IE6 SP1 (on Win2K) and see one cert validation requests, but if I use IE6 SP2 (on XP) 13 separate cert validation requests get fired off. Needless to say, this slows down my page load a lot. Firefox loads the page just fine with no unnecessary cert validation requests. The server is Apache running a pretty new lampp stack. All the server certificate / CA chain configurations seem to be fine (users can authenticate w/ trusted certs, the system can communicate to other systems with that server cert, etc.) Is there anything I can do from a configuration standpoint? Any other ideas at all?

• selecting ppp of multiple interfaces

  - by Neeraj

  Hi everyone, I am currently having a hard time on getting the mobile broadband connection running on ubuntu 10.04(lucid lynx). I am using a USB modem and used wvdial to connect to the web It went like: Sending ATZ ... OK sending some more flags OK modem initialized connecting Local IP x.x.x.x Remote IP y.y.y.y Primary DNS z.z.z.z Secondary DNS a.a.a.a (Some more output) I tested this with invalid username to make sure it is really connected and i think it was connected as connection failed with invalid usernames. Now when I do a remote ping say 8.8.8.8 (Google DNS servers), the ping says unreachable I think this might be because the system may be using the ethernet to send packets which was indeed disconnected. So can anyone help me out with this. How can I select ppp as the interface to send packets or is there some other problem. A command line solution will be appreciated as my network manager applet doesnt works correctly. Any help is much much appreciated. -- thx

• Deploying plugins for Internet Explorer

  - by Techpriester

  Hi everybody. I'm looking for a way to deploy an Internet Explorer plugin for SVG-rendering without manually installing it on every client machine. Is there a way to use some ActiveX voodoo stuff to automatically install a plugin? I have no reliable information about the IE versions that are used on the client side so I assume the worst: IE6. To make things even harder, the users probably don't have administrator privileges on the client machines. The whole thing happens in an enclosed local network, so security considerations are entirely secondary. It also does not really matter which actual plugin it will be, anything that can render SVG and run Javascript on it will do just fine. I can't think of anything to make this work so I'm desperate for help here...

• Why can't I access Jetty running on my Mac via my iPhone?

  - by bpapa

  I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

• malloc hangs in Linux

  - by Rahul

  I am using Linux on a 16 G with 2 quad core CPU. There are 8 processes which are doing some work (CPU intensive/network i/o). Out of which 4 have a memory leak (These are test conditions so no problem in having leaks here). Total space is occupied by all processes is around 15.4 G only 200 MB is free in system. Things are fine for some hours. But after that malloc hangs (for a process which doesn't have a memory leak). Its stuck for for more than 4 minutes (Note CPU is not 100% but io has gone up signficantly). Now there is no problem in the hanged process. (It has not corrupted the memory). What malloc is doing? (is it tryibg to defragment or builidng up swap space).I am using SUSE 10. Any pointers?

• Pass data in np.dnarray to Highcharts

  - by F.N.B

  I'm working with python 2.7, jinja2, flask and Highcharts. I create two numpy array (x1 and x2, type = numpy.dnarray) and I pass to Highcharts. My problems is, Highcharts don't recognize the commas in the vector. This is my jinja2 code: <script> $(function () { $('#container').highcharts({ series: [{ name: 'Tokyo', data: {{ x1 }} }, { name: 'London', data: {{ x2 }} }] }); }); And this is the error that I look with network chrome dev tools: series: [{ name: 'Tokyo', data: [1 4 5 2 3] }, { name: 'London', data: [3 6 7 4 1] }] I need change the numpy array to python list to pass to Highcharts or there is a better way to do?? Thanks

• Client / Server application for Video BroadCasting on LAN

  - by jbl

  I m much of a newbie to client/server applications and networking.I am currently starting up a project in which we are planning to create an application or something like a website accessible only to clients in that LAN network.We want the server to upload videos so that the clients can view them whenever they want.Also the clients can upload videos.Also we want some kind of registration to provide authentication to avoid bogus videos.Also additional features that can be added on later like comment section,ratings,Groups etc. Basically what we want is to build mini-youtube but with one major difference , we want the application to be LAN based. This is the idea behind the project.But we dont know where to start from as we are new to this stuff and also we have like 1 year to work on the project.Please guide me as to what all softwares i'll be needing to get this working !

• Depmod - unresolved symbols in rt73 module

  - by Xolstice

  I'm trying to install a linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the module. However, whenever I do a "make install", the make script executes a "depmod -a" command which then complains with the message: "Unresolved symbols in /lib/modules/2.4.37.9/extra/rt73.o". I then executed a "depmod -e" command to show unresolved symbols and it indicates the following information: request_firmware_Rsmp_38ce5074 release_firmware_Rsmp_33934162 I did a grep on the above information and it showed no source files making reference to it. I searched for it on google and it returned no results. Can anyone help?

• C# UDP Socket taking time to send data to unknown IP

  - by Mohsan

  Hi. i am sending data to UDP socket using this code Socket udpClient = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Parse(obj.destAddress), obj.destPort); byte[] buf = new byte[obj.length]; Array.Copy((byte[])obj.data, buf, obj.length); int n = udpClient.SendTo(buf, ipEndPoint); udpClient.Close(); this code works fine when IP exists in current network, but it takes 3-5 seconds when I send data to unknown IP address. This causes main application to hang for 3-5 seconds.. What could be the reason behind this problem..

• OS monitoring using JAVA

  - by Puneri

  I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

• Would it be simply better to use the system's functions rather than use the language?

  - by Nullw0rm

  There are many scenarios where I've questioned PHP's performance with some of its functions, and whether I should build a complex class to handle specific things using its seemingly slow tools. For example, Complex regular expressions with sed and processing with awk would seemingly be exponential in performance rather than making PHP's regular expression and seemingly excessive functions parse and in time manage to finish it. If I were to do a lot of network tasks such as MX lookups/DIGging/retrieving simultaneously I would rather pass it via system() and let the OS handle it itself. There are simply too many functions in PHP, that are inefficient and result in slow pages or can be handled easier by the OS. What are your opinions? Do you think I should do the hard work with the OS in its own/custom functions?

• Is select() Ok to implement single socket read/write timeout ?

  - by chmike

  I have an application processing network communication with blocking calls. Each thread manages a single connection. I've added a timeout on the read and write operation by using select prior to read or write on the socket. Select is known to be inefficient when dealing with large number of sockets. But is it ok, in term of performance to use it with a single socket or are there more efficient methods to add timeout support on single sockets calls ? The benefit of select is to be portable.

• What library to use to create a simple port scanner?

  - by durje

  I need advise to create a simple port-scanner, who will need to detect if some specific devices are connected to the network from theire IP/MAC address. I am working on windows 7 and can use preferably C++ Builder 2010 Embarcadero, or java or Qt. The library have to be under a public domain or equivalent, as my software is a proprietary software. What library would you advice? Do you know any free software that I could start from, or any examples? What about using Indy Sockets or Synapse TCP/IP Librarys? Thanks in advance.

• How to communicate with Telecom infrastructure using .NET

  - by Raiford

  I am currently writing some pretty gnarly C#/C++/Cli code to interface with Telecommunication equipement and GSM Mobile Networks for a couple of the major telecom here and abroad. GSM networks primarily use SS7 Signaling using a protocol called TCAP to send messages back and forth to Signaling Points within the network. The laws of Tcp/ip do not apply here :) I am very interested in hearing from others in this space specifically individuals using the .NET framework most likely using C# / C++. I have not come across any .NET libraries or tools to assist in this sort of development. Most of the software in this industry is "C" / Java based, as a result I have written tons of infrastructure .NET code using C# where possible and C++ / CLI to interface with hardware. Is anyone aware of any .NET language tools for this niche industry?

• How to implement bridging/NAT on linux? [closed]

  - by mikepurvis

  What I have is a network topology which looks like this: ------ PC --- IP Camera The PC has two ethernet interfaces, and is hosting a small webserver providing some auxiliary data. The issue is that the server on the PC runs on port 80, and the IP Camera is also running on port 80. Currently, we are bridging them, so that the PC's server is accessible at 192.168.0.2 and the camera at 192.168.0.3. However, what I'm trying to explore is the feasibility of using the PC to expose them both on the PC's IP, ideally both on port 80. Can this be done with regular sockets, or will it be necessary to use raw sockets?
