  • how can i access C# dll from VBScript on client machine

    - by maraheem
    i have created a C# dll file on my machine as shown below: namespace myDLL { public class myClass { public string myFunction() { return "I am Here"; } } } then i created a tlb file with "tlbexp" command, then i used the "regasm" command n registered this dll on my machine. When i created an object of type myClass on my machine using VBScript, everything is working fine... here i used the CreateObject() method as shown below: Set myObj = CreateObject("myDll.myClass") Now i want to create an object of type myClass from VBScript that is running on another machine, how can i do this. please help me how can i access that dll file, am using the CreateObject() function as shown below: Set HD = CreateObject("myDll.myClass","myMachineName") now am getting error as "permission denied"

  • Client to server data upload

    - by RickBowden
    I'm trying to design a system similar to the traditional server monitoring systems like MOM, Tivoli, Open View, where an agent will record data and then upload it to a central database once a day, but them also be able to send immediate alerts back to the server. I'm not sure what the best methodology might be for this. I've started looking at Microsoft sync services but I'm not sure if it will fit my needs. I'm using VS2008 and C#. Does anyone have any experience or ideas about how I should go about this task?

  • How to properly do weapon cool-down reload timer in multi-player laggy environment?

    - by John Murdoch
    I want to handle weapon cool-down timers in a fair and predictable way on both client on server. Situation: Multiple clients connected to server, which is doing hit detection / physics Clients have different latency for their connections to server ranging from 50ms to 500ms. They want to shoot weapons with fairly long reload/cool-down times (assume exactly 10 seconds) It is important that they get to shoot these weapons close to the cool-down time, as if some clients manage to shoot sooner than others (either because they are "early" or the others are "late") they gain a significant advantage. I need to show time remaining for reload on player's screen Clients can have clocks which are flat-out wrong (bad timezones, etc.) What I'm currently doing to deal with latency: Client collects server side state in a history, tagged with server timestamps Client assesses his time difference with server time: behindServerTimeNs = (behindServerTimeNs + (System.nanoTime() - receivedState.getServerTimeNs())) / 2 Client renders all state received from server 200 ms behind from his current time, adjusted by what he believes his time difference with server time is (whether due to wrong clocks, or lag). If he has server states on both sides of that calculated time, he (mostly LERP) interpolates between them, if not then he (LERP) extrapolates. No other client-side prediction of movement, e.g., to make his vehicle seem more responsive is done so far, but maybe will be added later So how do I properly add weapon reload timers? My first idea would be for the server to send each player the time when his reload will be done with each world state update, the client then adjusts it for the clock difference and thus can estimate when the reload will be finished in client-time (perhaps considering also for latency that the shoot message from client to server will take as well?), and if the user mashes the "shoot" button after (or perhaps even slightly before?) that time, send the shoot event. The server would get the shoot event and consider the time shot was made as the server time when it was received. It would then discard it if it is nowhere near reload time, execute it immediately if it is past reload time, and hold it for a few physics cycles until reload is done in case if it was received a bit early. It does all seem a bit convoluted, and I'm wondering whether it will work (e.g., whether it won't be the case that players with lower ping get better reload rates), and whether there are more elegant solutions to this problem.

  • configure pppoe on wrt54gl(openwrt)

    - by sunny
    Hi, I have home DSL connection from my ISP with a beetel modem at my end. I want to make my network wireless, so i bought a linksys wrt54gl and installed open-wrt on it. My ISP provides dynamic IP's with me connecting via pppoe. My question is how do I configure openwrt to work with this. Please suggest what option should I go with, or any other you recommend. DSL cable--Beetel Modem-- Wrt54gl in bridge mode with beetel modem doing the pppoe and having a DHCP server. DSL cable--Wrt54gl with wrt54gl handling the pppoe. Is option 2 possible, can I have a setup without bringing the beetel modem in the picture at all?

  • Can't seem to get C TCP Server-Client Communications Right

    - by Zeesponge
    Ok i need some serious help here. I have to make a TCP Server Client. When the Client connects to server using a three stage handshake. AFterwards... while the Client is running in the terminal, the user enters linux shell commands like xinput list, ls -1, ect... something that uses standard output. The server accepts the commands and uses system() (in a fork() in an infinite loop) to run the commands and the standard output is redirected to the client, where the client prints out each line. Afterward the server sends a completion signal of "\377\n". In which the client goes back to the command prompt asking for a new command and closes its connection and exit()'s when inputting "quit". I know that you have to dup2() both the STDOUT_FILENO and STDERR_FILENO to the clients file descriptor {dup2(client_FD, STDOUT_FILENO). Everything works accept when it comes for the client to retrieve system()'s stdout and printing it out... all i get is a blank line with a blinking cursor (client waiting on stdin). I tried all kinds of different routes with no avail... If anyone can help out i would greatly appreciate it TCP SERVER CODE include #include <sys/socket.h> #include <stdio.h> #include <string.h> #include <netinet/in.h> #include <signal.h> #include <unistd.h> #include <stdlib.h> #include <errno.h> //Prototype void handle_client(int connect_fd); int main() { int server_sockfd, client_sockfd; socklen_t server_len, client_len; struct sockaddr_in server_address; struct sockaddr_in client_address; server_sockfd = socket(AF_INET, SOCK_STREAM, 0); server_address.sin_family = AF_INET; server_address.sin_addr.s_addr = htonl(INADDR_ANY); server_address.sin_port = htons(9734); server_len = sizeof(server_address); bind(server_sockfd, (struct sockaddr *)&server_address, server_len); /* Create a connection queue, ignore child exit details and wait for clients. */ listen(server_sockfd, 10); signal(SIGCHLD, SIG_IGN); while(1) { printf("server waiting\n"); client_len = sizeof(client_address); client_sockfd = accept(server_sockfd, (struct sockaddr *)&client_address, &client_len); if(fork() == 0) handle_client(client_sockfd); else close(client_sockfd); } } void handle_client(int connect_fd) { const char* remsh = "<remsh>\n"; const char* ready = "<ready>\n"; const char* ok = "<ok>\n"; const char* command = "<command>\n"; const char* complete = "<\377\n"; const char* shared_secret = "<shapoopi>\n"; static char server_msg[201]; static char client_msg[201]; static char commands[201]; int sys_return; //memset client_msg, server_msg, commands memset(&client_msg, 0, sizeof(client_msg)); memset(&server_msg, 0, sizeof(client_msg)); memset(&commands, 0, sizeof(commands)); //read remsh from client read(connect_fd, &client_msg, 200); //check remsh validity from client if(strcmp(client_msg, remsh) != 0) { errno++; perror("Error Establishing Handshake"); close(connect_fd); exit(1); } //memset client_msg memset(&client_msg, 0, sizeof(client_msg)); //write remsh to client write(connect_fd, remsh, strlen(remsh)); //read shared_secret from client read(connect_fd, &client_msg, 200); //check shared_secret validity from client if(strcmp(client_msg, shared_secret) != 0) { errno++; perror("Invalid Security Passphrase"); write(connect_fd, "no", 2); close(connect_fd); exit(1); } //memset client_msg memset(&client_msg, 0, sizeof(client_msg)); //write ok to client write(connect_fd, ok, strlen(ok)); // dup2 STDOUT_FILENO <= client fd, STDERR_FILENO <= client fd dup2(connect_fd, STDOUT_FILENO); dup2(connect_fd, STDERR_FILENO); //begin while... while read (client_msg) from server and >0 while(read(connect_fd, &client_msg, 200) > 0) { //check command validity from client if(strcmp(client_msg, command) != 0) { errno++; perror("Error, unable to retrieve data"); close(connect_fd); exit(1); } //memset client_msg memset(&client_msg, 0, sizeof(client_msg)); //write ready to client write(connect_fd, ready, strlen(ready)); //read commands from client read(connect_fd, &commands, 200); //run commands using system( ) sys_return = system(commands); //check success of system( ) if(sys_return < 0) { perror("Invalid Commands"); errno++; } //memset commands memset(commands, 0, sizeof(commands)); //write complete to client write(connect_fd, complete, sizeof(complete)); } } TCP CLIENT CODE #include <sys/types.h> #include <sys/socket.h> #include <stdio.h> #include <string.h> #include <netinet/in.h> #include <arpa/inet.h> #include <unistd.h> #include <stdlib.h> #include <errno.h> #include "readline.c" int main(int argc, char *argv[]) { int sockfd; int len; struct sockaddr_in address; int result; const char* remsh = "<remsh>\n"; const char* ready = "<ready>\n"; const char* ok = "<ok>\n"; const char* command = "<command>\n"; const char* complete = "<\377\n"; const char* shared_secret = "<shapoopi>\n"; static char server_msg[201]; static char client_msg[201]; memset(&client_msg, 0, sizeof(client_msg)); memset(&server_msg, 0, sizeof(server_msg)); /* Create a socket for the client. */ sockfd = socket(AF_INET, SOCK_STREAM, 0); /* Name the socket, as agreed with the server. */ memset(&address, 0, sizeof(address)); address.sin_family = AF_INET; address.sin_addr.s_addr = inet_addr(argv[1]); address.sin_port = htons(9734); len = sizeof(address); /* Now connect our socket to the server's socket. */ result = connect(sockfd, (struct sockaddr *)&address, len); if(result == -1) { perror("ACCESS DENIED"); exit(1); } //write remsh to server write(sockfd, remsh, strlen(remsh)); //read remsh from server read(sockfd, &server_msg, 200); //check remsh validity from server if(strcmp(server_msg, remsh) != 0) { errno++; perror("Error Establishing Initial Handshake"); close(sockfd); exit(1); } //memset server_msg memset(&server_msg, 0, sizeof(server_msg)); //write shared secret text to server write(sockfd, shared_secret, strlen(shared_secret)); //read ok from server read(sockfd, &server_msg, 200); //check ok velidity from server if(strcmp(server_msg, ok) != 0 ) { errno++; perror("Incorrect security phrase"); close(sockfd); exit(1); } //?

  • Kindle (client) for Mac--text search or highlighting/notes?

    - by doug
    just so we're clear, i'm talking about the client/software version here--ie, that you install on your Mac or PC--not the device. The Kindle client was recently released for the Mac. I downloaded it and bought a couple of Kindle-edition books to view on this client. Astonishingly, two features i consider to be more or less essential to any ebook reader are missing in the Kindle client, either that, or i can't find them: (i) text searching; and (ii) highlighting text. First, does anyone know how to access the search feature? I'm aware of the "Go To" button at the top middle of the reader window--the options in that menu when you click the button are: "Cover", "Table of Contents", "Beginning" and "Location." "Location" requires that you type in an integer (but it doesn't correspond to page number--e.g., typing "167" brought me to the table of contents), not a search term. Second, there's a button on the upper right-hand corner of the window "Show Notes and Marks" yet i can't find any way to highlight text. The only kind of "note" or "mark" i have been able to record is to "bookmark" a page by clicking the "bookmark" button also at the top of the window.

  • Nginx and client certificates from hierarchical OpenSSL-based certification authorities

    I'm trying to set up root certification authority, subordinate certification authority and to generate the client certificates signed by any of this CA that nginx 0.7.67 on Debian Squeeze will accept.

  • Is a Model Driven Architecture in Language Oriented Programming (MPS) feasible at this time

    - by Steven Jeuris
    As a side project I am developing some sort of DSL where I describe a data model, and generate desired code files from it. I believe this is called Model Driven Architecture. My partial existing implementation uses C#, CodeDOM, XML and XSLT to do this manually. I discovered there already exist better environments to do this in. The one which fascinated me the most is called MPS, which follows the Language Oriented Programming paradigm. This article, written by a cofounder of JetBrains was a real eye opener for me. I truly believe LOP has a very good chance of becoming the next big programming paradigm once it has broader support. From my short experience with MPS, I noticed it is still mainly Java-oriented. My question is, how feasible is it to generate code files for other (multiple) languages instead of just Java. I don't need full language support from the start, so preferably, I need to be able to implement a language in a agile way. E.g. first support only one type, add access modifiers, ... Perhaps some other (free) environment already provides this out of the box. P.S.: I find it important to have a lot of control over the naming conventions and such of the generated code. This is one of the reasons why I started my own implementation.

  • When trying to copy a virtual disk in VMware vSphere client, I get an errror.

    - by Zak
    I'm pretty new to all the VMware world, so this is probably mainly a question about the right set of documentation to look at. I'm trying to clone/copy a VM that I installed on an ESXi installation. I was trying to follow along with the top example here: http://serverfault.com/questions/16320/is-there-a-way-to-clone-an-existing-vm-on-an-esxi-server-without-having-to-re-imp However, I'm using the vSphere client to connect to the ESXi box and manage it, and the vSphere client is telling me it won't let me rename the vmdk file. The real answer I want is how do I clone the VM I installed if I want to spin up 5 copies. Is there another utility I can use to copy the vmdk file, then create a new virtual machine using it? Any idea why they nerfed the feature in vSphere client?

  • How to use Client for NFS on Windows Vista?

    - by netvope
    I've installed "Client for NFS" on my 32-bit Windows Vista Ultimate. However, I can't find it in the start menu, and can't find any documentation on how to use it. How do I connect to a NFS share using "Client for NFS"? Can I map it to a drive letter? How do I choose connection options, such as my uid/gid, mount as read-only, port number, etc? Ideally I would like to map a NFS share using the command line. You may also suggest alternatives to "Client for NFS".

  • Need an FTP Client to run on a server and allow scheduling and not need a login to run

    - by William Todd Salzman
    I am looking at FTP clients to transfer from an external FTP Server. I need to place this FTP client on a server in the DMZ that will not be routinely logged in, so the client needs to run as a service or something like that? I need the client to be able to retrieve files from the server on a schedule (Tuesday Mornings) and drop them in a local directory for pickup by another process. I would also like the solution to be capable of performing sftp transfers. Most marketing material is geared towards the person who will be running this on their desktop, not on a server, so several of my points are never in the product specs. update DMZ can run either Windows versions or Linux versions * end update *

  • How to store an object in Riak with the Java client?

    - by Jonas
    I have setup Riak on a Ubuntu machine, and it seam to work if I do riak ping. Now I would like to use the Riak Java client to store an object, but it doesn't work. I get com.basho.riak.client.response.RiakIORuntimeException when I try to store an object. What am I doing wrong? Is there a way to test if I can access riak from my java client? Do I have to create a Bucket first? how? import com.basho.riak.client.RiakClient; import com.basho.riak.client.RiakObject; import com.basho.riak.client.response.FetchResponse; public class RiakTest { public static void main(String[] args) { // connect RiakClient riak = new RiakClient("http://192.168.1.107:8098/riak"); // create object RiakObject o = new RiakObject("mybucket", "mykey", "myvalue"); // store riak.store(o); } }

  • WCF net.tcp server disconnects - how to handle properly on client side?

    - by RoastedBattleSquirrel
    I'm stuck with a bit of an annoying problem right now. I've got a Silverlight 4 application (which runs OOB by default). It uses WCF with net.tcp as means of communicating with the server. The client uses a central instance of the wcf client proxy. As long as everything keeps running on the server side, everything's fine. If i kill the server in the middle of everything, i drown in an avalanche of exceptions on the client side (connection lost, channel faulted etc etc). Now i'm looking for a way to handle this in a clean and centralized way (if centralized is possible). The SL app has one central client object sitting in App.cs (public static MyClient Client { get;set;}), which gets initialized on application start. Any idea how to properly handle any connectivity problems on the client object?

  • Discussion of a Distributed Data Storage implementation

    - by fegol
    I want to implement a distributed data storage using a client/server architecture. Each data item will be stored persistently in disk in one of several remote servers. The client uses a library to update and query the data, shielding the client from its actual location. This should allow a client to associate keys (String) to values(byte[]), much as a Map does. The system must ensure that the amount of data stored in each server is approximately the same. The set of servers is known beforehand by other servers and clients. Both the client and the server will be written in Java, using sockets, threads, and files. I open this topic with the objective of discussing the best way to implement this idea, assuming simplicity, what are the issues of this implementation, performance measurements and discussion of the limitations.

  • OpenVPN Client timing out

    - by Austin
    I recently installed OpenVPN on my Ubuntu VPS. Whenenver I try to connect to it, I can establish a connection just fine. However, everything I try to connect to times out. If I try to ping something, it will resolve the IP, but will time out after resolving the IP. (So DNS Server seems to be working correctly) My server.conf has this relevant information (At least I think it's relevant. I'm not sure if you need more or not) # Which local IP address should OpenVPN # listen on? (optional) ;local a.b.c.d # Which TCP/UDP port should OpenVPN listen on? # If you want to run multiple OpenVPN instances # on the same machine, use a different port # number for each one. You will need to # open up this port on your firewall. port 1194 # TCP or UDP server? ;proto tcp proto udp # "dev tun" will create a routed IP tunnel, # "dev tap" will create an ethernet tunnel. # Use "dev tap0" if you are ethernet bridging # and have precreated a tap0 virtual interface # and bridged it with your ethernet interface. # If you want to control access policies # over the VPN, you must create firewall # rules for the the TUN/TAP interface. # On non-Windows systems, you can give # an explicit unit number, such as tun0. # On Windows, use "dev-node" for this. # On most systems, the VPN will not function # unless you partially or fully disable # the firewall for the TUN/TAP interface. ;dev tap dev tun # Windows needs the TAP-Win32 adapter name # from the Network Connections panel if you # have more than one.

  • Python soap using soaplib (server) and suds (client)

    - by Celso Axelrud
    This question is related to: http://stackoverflow.com/questions/1751027/python-soap-server-client In the case of soap with python, there are recommendation to use soaplib (http://wiki.github.com/jkp/soaplib) as soap server and suds (https://fedorahosted.org/suds/) as soap client. My target is to create soap services in python that can be consumed by several clients (java, etc). I tried the HelloWorld example from soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). It works well when the client is also using soaplib. Then, I tried to use suds as client consuming the HelloWorld services and it fail. -Why this is happening? Does soaplib server has problems to consumed by different clients? Here the code for the server: from soaplib.wsgi_soap import SimpleWSGISoapApp from soaplib.service import soapmethod from soaplib.serializers.primitive import String, Integer, Arraycode class HelloWorldService(SimpleWSGISoapApp): @soapmethod(String,Integer,_returns=Array(String)) def say_hello(self,name,times): results = [] for i in range(0,times): results.append('Hello, %s'%name) return results if __name__=='__main__': from cherrypy.wsgiserver import CherryPyWSGIServer #from cherrypy._cpwsgiserver import CherryPyWSGIServer # this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0 server = CherryPyWSGIServer(('localhost',7789),HelloWorldService()) server.start() This is the soaplib client: from soaplib.client import make_service_client from SoapServerTest_1 import HelloWorldService client = make_service_client('http://localhost:7789/',HelloWorldService()) print client.say_hello("Dave",5) Results: >>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave'] This is the suds client: from suds.client import Client url = 'http://localhost:7789/HelloWordService?wsdl' client1 = Client(url) client1.service.say_hello("Dave",5) Results: >>> Unhandled exception while debugging...

  • Is there a client for Google Talk, for Mac, that allows phone calls?

    - by xtraorange
    I'm having no luck finding a client for Google Talk that is both for Mac (OSX) and that allows phone calls (not just chatting with other Google Talk users). If I leave the browser page open to gmail, it will ring when I receive a call to my Google Voice number, and I can call out from my Google Voice number, but I don't want to use the browser. Is there any sort of client, for Mac, that will allow calls through Google Talk?

    Hi All, I am trying to download the latest Cisco VPN Client for OS X. I get here:http://www.versiontracker.com/dyn/moreinfo/macosx/12696 I click to download, I get redirected to Cisco, I create an account, try to download again and they tell me that I need to have a valid technical support agreement to get access to the software. Really? How do they expect us to VPN into client networks?

  • What is the difference between the Client and GTK versions of emacs?

    - by David
    My Ubuntu 10.04 desktop has three versions of emacs: emacs-snapshot (client) emacs-snapshot (GTK) GNU Emacs 23 I mostly use emacs-snapshot, but I also use regular emacs in terminal mode emacs -nw. However, it is not clear to me what the difference is between the client and GTK versions of emacs-snapshot is, which one is launched by emacs-snapshot at the terminal, and if I should uninstall one or just ignore it.

  • WIF, ADFS 2 and WCF&ndash;Part 4: Service Client (using Service Metadata)

    - by Your DisplayName here!
    See parts 1, 2 and 3 first. In this part we will finally build a client for our federated service. There are basically two ways to accomplish this. You can use the WCF built-in tooling to generate client and configuration via the service metadata (aka ‘Add Service Reference’). This requires no WIF on the client side. Another approach would be to use WIF’s WSTrustChannelFactory to manually talk to the ADFS 2 WS-Trust endpoints. This option gives you more flexibility, but is slightly more code to write. You also need WIF on the client which implies that you need to run on a WIF supported operating system – this rules out e.g. Windows XP clients. We’ll start with the metadata way. You simply create a new client project (e.g. a console app) – call ‘Add Service Reference’ and point the dialog to your service endpoint. What will happen then is, that VS will contact your service and read its metadata. Inside there is also a link to the metadata endpoint of ADFS 2. This one will be contacted next to find out which WS-Trust endpoints are available. The end result will be a client side proxy and a configuration file. Let’s first write some code to call the service and then have a closer look at the config file. var proxy = new ServiceClient(); proxy.GetClaims().ForEach(c =>     Console.WriteLine("{0}\n {1}\n  {2} ({3})\n",         c.ClaimType,         c.Value,         c.Issuer,         c.OriginalIssuer)); That’s all. The magic is happening in the configuration file. When you in inspect app.config, you can see the following general configuration hierarchy: <client /> element with service endpoint information federation binding and configuration containing ADFS 2 endpoint 1 (with binding and configuration) ADFS 2 endpoint n (with binding and configuration) (where ADFS 2 endpoint 1…n are the endpoints I talked about in part 1) You will see a number of <issuer /> elements in the binding configuration where simply the first endpoint from the ADFS 2 metadata becomes the default endpoint and all other endpoints and their configuration are commented out. You now need to find the endpoint you want to use (based on trust version, credential type and security mode) and replace that with the default endpoint. That’s it. When you call the WCF proxy, it will inspect configuration, then first contact the selected ADFS 2 endpoint to request a token. This token will then be used to authenticate against the service. In the next post I will show you the more manual approach using the WIF APIs.

  • Advantages to Server Scripting languages over Client Side Scripting languages

    There are numerous advantages to server scripting languages over client side scripting languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripts are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9+ years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality: Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server side and client side scripts used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid.
