  • VirtualBox Port Forward not working when Guest IP *IS* specified (while doc says opposite)

    - by Patrick
    Trying to port forward from host (Mac OS X) 127.0.0.1:8282 - guest (CentOS)'s 10.10.10.10:8080. Existing port forwards include 127.0.0.1:8181 and 9191 to guest without any IP specified (so whatever it gets through DHCP, as explained in the documentation). Here is how the non-working binding was added: VBoxManage modifyvm "VM name" --natpf1 "rule3,tcp,127.0.0.1,8282,10.10.10.10,8080" Here is how the working ones were added: VBoxManage modifyvm "VM name" --natpf1 "rule1,tcp,127.0.0.1,8181,,80" VBoxManage modifyvm "VM name" --natpf1 "rule2,tcp,127.0.0.1,9191,,9090" And by "non-working", I of course mean not listening (as a prerequisite to forwarding): $ lsof -Pi -n|grep Virtual|grep LISTEN VirtualBo 27050 user 21u IPv4 0x2bbdc68fd363175d 0t0 TCP 127.0.0.1:9191 (LISTEN) VirtualBo 27050 user 22u IPv4 0x2bbdc68fd0e0af75 0t0 TCP 127.0.0.1:8181 (LISTEN) There should be a similar line above but with 127.0.0.1:8282. Just to be clear, this port is listening perfectly fine on the guest itself. And when I remove the guest IP (i.e., clear the 10.10.10.10) the forward works fine, albeit to eth0 (not eth1 where I need it). I can tcpdump and watch the traffic flow back and forth. And yes, I've disabled iptables entirely while testing -- it's not getting blocked anywhere on the guest. As VirtualBox writes in their documentation, you are required to specify the guest IP if it's static (makes sense, no DHCP record it keeps): "If for some reason the guest uses a static assigned IP address not leased from the built-in DHCP server, it is required to specify the guest IP when registering the forwarding rule:". However, doing so (as I need to), seems to break the port forward with nary a report in any log file I can find. (I've reviewed everything in ~/Library/VirtualBox/). Other notes: While I used the above command to add the third rule, I've also verified it showed up correctly in GUI and then removed/re-added from there just to make sure). This forum link -- while very dated -- looks somewhat related in that a port forward to a static IP was not appearing (perhaps they think due to lack of gratuitous arp being sent for host to know IP is there/avail?). Anyway, what gives? Is this still buggy? Any suggestions? If not, easy enough workarounds? What's interesting is that this works perfectly fine on another user's Mac, however he's running a slightly older version (4.3.6 v. 4.3.12).

  • Android device unable to obtain ip address connecting to AP created with Hostapd

    - by user114392
    I have a wired internet connection that works behind an authenticated proxy server. I followed the steps mentioned here and managed to create a hotspot which my google nexus 7 detects. However, it seems stuck at "obtaining an ip address" and is not able to connect to the internet. I initially received the following error message when running the script in the terminal: dnsmasq: failed to create listening socket for 127.0.0.1: Address already in use [fail] I figured it is because of a conflict with the network manager, I commented out the "dns=dnsmasq" line in the nm configuration file. After a network-manager restart, the first error doesn't show up but I get the following: Configuration file: /etc/hostapd.conf Failed to create interface mon.wlan0: -23 (Too many open files in system) Try to remove and re-create mon.wlan0 In both cases, however, the hotspot is created and is detected by my android device. only that it cannot "obtain an ip address" and connect to it. Is it because my eth0 connects via a proxy server? Or could there be something wrong with the dnsmasq config? Any help would be appreciated.

  • Run WCF ServiceHost with multiple contracts

    - by Sam
    Running a ServiceHost with a single contract is working fine like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.Open(); Now I'd like to add a second (3rd, 4th, ...) contract. My first guess would be to just add more endpoints like this: servicehost = new ServiceHost(typeof(MyService1)); servicehost.AddServiceEndpoint(typeof(IMyService1), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService1"); servicehost.AddServiceEndpoint(typeof(IMyService2), new NetTcpBinding(), "net.tcp://127.0.0.1:800/MyApp/MyService2"); servicehost.Open(); But of course this does not work, since in the creation of ServiceHost I can either pass MyService1 as parameter or MyService2 - so I can add a lot of endpoints to my service, but all have to use the same contract, since I only can provide one implementation? I got the feeling I'm missing the point, here. Sure there must be some way to provide an implementation for every endpoint-contract I add, or not?

  • Enteprise Library Exception Handling for WCF Fault Contracts - CLIENT SIDE

    - by Huw
    I have a Windows Service which communicates with WCF services. The WCF services are all fault shielded and generate custom UserFaultContracts and ServiceFaultContracts. No problems there. In the Windows Service I am using EntLib for exception handling and logging. I do not want to try catch for faults try { } catch (FaultException<UserFaultContract>) { } I want to use EntLib try { } catch (Exception ex) { var rethrow = ExceptionPolicy.HandleException(ex, "Transaction Policy"); if (rethrow) throw; } This also works, however, in my Tranasaction Policy I want to Log the details of the UserFaultContract. This is where I am unglued. And I hate becoming unglued. The fault is captured and logged...but I can't get the details of the fault. My exception policy is <add name="Transaction Policy"> <exceptionTypes> <add type="System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" postHandlingAction="None" name="Exception"> <exceptionHandlers> <add logCategory="General" eventId="200" severity="Error" title="Transaction Error" formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" priority="2" useDefaultLogger="true" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Logging Handler" /> </exceptionHandlers> </add> <add type="System.ServiceModel.FaultException, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" postHandlingAction="None" name="FaultException"> <exceptionHandlers> <add logCategory="General" eventId="200" severity="Error" title="Service Fault" formatterType="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.TextExceptionFormatter, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" priority="2" useDefaultLogger="true" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Logging Handler" /> </exceptionHandlers> </add> </exceptionTypes> </add> The exception logged is: Timestamp: 5/13/2010 14:53:40 Message: HandlingInstanceID: e9038634-e16e-4d87-ab1e-92379431838b An exception of type 'System.ServiceModel.FaultException`1[[LCI.DispatchMaster.FaultContracts.ServiceFaultContract, LCI.DispatchMaster.FaultContracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' occurred and was caught. 05/13/2010 10:53:40 Type : System.ServiceModel.FaultException`1[[LCI.DispatchMaster.FaultContracts.ServiceFaultContract, LCI.DispatchMaster.FaultContracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : There was an internal fault at the DispatchMaster service.

I would, as you can see, like the ID and Message to be logged by EntLib. I am assuming that I'm going to have to write a custom handler to exctract the fault details - but thought I'd ask if I'm missing something in EntLib which might help me avoid that task. Thanks to anyone who is willing to help.

  • How to get the client ip address in ASP.Net MVC?

    - by melaos
    hi guys, i'm totally new to the asp.net mvc stack and i was wondering what happened to the simple Page object and the Request ServerVariables object? basically what i wanted to do is to pull out the client's pc ip address. but i fail to understand how the current MVC structure has changed all of this. as far as i can understand, most of the variable object has been replaced by the HttpRequest variants? anybody care to share some resources? really a sea of stuff to learn in the asp.net mvc world :) thanks.

  • subclassing and data contracts

    - by Sergio Romero
    I'm playing with the following code: [ServiceContract] public interface IUserAccountService { [OperationContract] UserAccountResponse CreateNewUserAccount(UserAccountRequest userAccountRequest); } public abstract class BaseResponse { public bool Success { get; set; } public string Message { get; set; } } public class UserAccountResponse : BaseResponse { public int NewUserId { get; set; } } My questions are: Do I need to add the DataContract attribute to both the abstract class and the subclass? If the abstract class does not need the DataContract attribute, can I add the DataMember attribure to its properties?

  • WCF contracts - namespaces and SerializationExceptions

    - by qntmfred
    I am using a third party web service that offers the following calls and responses http://api.athirdparty.com/rest/foo?apikey=1234 <response> <foo>this is a foo</foo> </response> and http://api.athirdparty.com/rest/bar?apikey=1234 <response> <bar>this is a bar</bar> </response> This is the contract and supporting types I wrote [ServiceContract] [XmlSerializerFormat] public interface IFooBarService { [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "foo?key={apikey}")] FooResponse GetFoo(string apikey); [OperationContract] [WebGet( BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Xml, UriTemplate = "bar?key={apikey}")] BarResponse GetBar(string apikey); } [XmlRoot("response")] public class FooResponse { [XmlElement("foo")] public string Foo { get; set; } } [XmlRoot("response")] public class BarResponse { [XmlElement("bar")] public string Bar { get; set; } } and then my client looks like this static void Main(string[] args) { using (WebChannelFactory<IFooBarService> cf = new WebChannelFactory<IFooBarService>("thirdparty")) { var channel = cf.CreateChannel(); FooResponse result = channel.GetFoo("1234"); } } When I run this I get the following exception Unable to deserialize XML body with root name 'response' and root namespace '' (for operation 'GetFoo' and contract ('IFooBarService', 'http://tempuri.org/')) using XmlSerializer. Ensure that the type corresponding to the XML is added to the known types collection of the service. If I comment out the GetBar operation from IFooBarService, it works fine. I know I'm missing an important concept here - just don't know quite what to look for. What is the proper way to construct my contract types, so that they can be properly deserialized?

  • IP address detection for geo-location or MAC address much secure?

    - by SuperRomia
    Recent study many websites are using geo-location technology on their Websites. I'm planning to implement one website which can be detect the web visitor more accurate. An found that Mozilla is using some kind of detect MAC address technology in their Geo-Location web service. Is it violate some privacy issue? I believe most of Geo-location service providers only offer country to city level. But the Mac address detection enable to locate the web visitors' location more correctly than using IP address detection. If detect the MAC address is not practical, which geo-location service provider is offering more accurate data to detect my Website visitor around the world?

  • For reliable code, NModel, Spec Explorer, F# or other?

    - by ja
    I've got a business app in C#, with unit tests. Can I increase the reliability and cut down on my testing time and expense by using NModel or Spec Explorer? Alternately, if I were to rewrite it in F# (or even Haskell), what kinds (if any) of reliability increase might I see? Code Contracts? ASML? I realize this is subjective, and possibly argumentative, so please back up your answers with data, if possible. :) Or maybe an worked example, such as Eric Evans Cargo Shipping System? If we consider Unit tests to be pecific and strong theorems, checked quasi-statically on particular “interesting instances” and Types to be general but weak theorems (usually checked statically), and contracts to be general and strong theorems, checked dynamically for particular instances that occur during regular program operation (from B. Pierce's Types Considered Harmful, where do these other tools fit? We could pose the analogous question for Java, using Java PathFinder, Scala, etc.

  • Are MEF's ComposableParts contracts instance-based?

    - by Dave
    I didn't really know how to phrase the title of my questions, so my apologies in advance. I read through parts of the MEF documentation to try to find the answer to my question, but couldn't find it. I'm using ImportMany to allow MEF to create multiple instances of a specific plugin. That plugin Imports several parts, and within calls to a specific instance, it wants these Imports to be singletons. However, what I don't want is for all instances of this plugin to use the same singleton. For example, let's say my application ImportManys Blender appliances. Every time I ask for one, I want a different Blender. However, each Blender Imports a ControlPanel. I want each Blender to have its own ControlPanel. To make things a little more interesting, each Blender can load BlendPrograms, which are also contained within their own assemblies, and MEF takes care of this loading. A BlendProgram might need to access the ControlPanel to get the speed, but I want to ensure that it is accessing the correct ControlPanel (i.e. the one that is associated with the Blender that is associated with the program!) This diagram might clear things up a little bit: As the note shows, I believe that the confusion could come from an inherently-poor design. The BlendProgram shouldn't touch the ControlPanel directly, and instead perhaps the BlendProgram should get the speed via the Blender, which will then delegate the request to its ControlPanel. If this is the case, then I assume the BlendProgram needs to have a reference to a specific Blender. In order to do this, is the right way to leverage MEF and use an ImportingConstructor for BlendProgram, i.e. [ImportingConstructor] public class BlendProgram : IBlendProgram { public BlendProgram( Blender blender) {} } And if this is the case, how do I know that MEF will use the intended Blender plugin?

  • Service Contracts with Message causes duplicate proxy classes

    - by jaklucky
    Hi, I have a service contract with Message as shown below. [OperationContract] Message MyMethodWithMessage(Message myMsgParam); Everything works fine. I could host my services. But when I try to create proxies through "Add Service References", I am getting the duplicate proxy classes. If I take out the above OperationContract and re run my services and try to create proxies, then "Add Service References" does not provide duplicate proxies. I am really confused about this!!! Any help is greatly appreciated... Thank you, Suresh

  • Entity Framework 4 + POCO with custom classes and WCF contracts (serialization problem)

    - by eman
    Yesterday I worked on a project where I upgraded to Entity Framework 4 with the Repository pattern. In one post, I have read that it is necessary to turn off the custom tool generator classes and then write classes (same like entites) by hand. That I can do it, I used the POCO Entity Generator and then deleted the new generated files .tt and all subordinate .cs classes. Then I wrote the "entity classes" by myself. I added the repository pattern and implemented it in the business layer and then implemented a WCF layer, which should call the methods from the business layer. By calling an Insert (Add) method from the presentation layer and everything is OK. But if I call any method that should return some class, then I get an error like (the connection was interrupted by the server). I suppose there is a problem with the serialization or am I wrong? How can by this problem solved? I'm using Visual Studio S2010, Entity Framework 4, C#. UPDATE: I have uploaded the project and hope somebody can help me! link text UPDATE 2: My questions: Why is POCO good (pros/cons)? When should POCO be used? Is POCO + the repository pattern a good choice? Should POCO classes by written by myself or could I use auto generated POCO classes?

  • Windows 7 Default Gateway problem

    - by Matt
    Hi, I have a strange problem (or at least seems strange to me) the below are IP configurations for two laptops on my home network which consists of a main router 192.168.11.1 and a connected wireless router (i know this can cause problems but has always worked until I got the win7 machine) at 192.168.11.2 with DHCP disabled. Laptop 1 - Win XP IP: Dynamically assigned by main router default gateway: 192.168.11.1 (main router) This machine gets perfect connectivity. Laptop 2 - Win7 IP: dynamically assigned by main router Default Gateway: 192.168.11.2 THIS IS THE PROBLEM... I cannot seem to get this machine to default to the main router for the gateway UNLESS I go to a static configuration which I would rather not do since I regularly go between my home and public networks. Why is my Win7 machine not finding the main gateway the same way that the other laptop is? I believe that the rest of my setup is fine as it has always worked and it works perfectly when set as static ip and gateway. Please help! Thanks

  • Problem with DNS

    - by dotNET
    Hey, I bought a new website, and the company gived me another free domain name, so when I asked for the socond they created it and they told me to change the DNS to look like the first one. It's been a week waiting for it to propagate, today when I type the url I got this error message : If you are the web site owner, it is possible you have reached this page because: * The IP address has changed. * There has been a server misconfiguration. * The site may have been moved to a different server. If you are the owner of this website and were not expecting to see this page, please contact your hosting provider. When I try to add the second domain to my cpanel (Addon domain) I get also another error : The addon domain “abcdef.com” has been created. An account with that login already exists. Do you have any ideas about this problem. Thanks. EDIT I tried to flush the DNS with ipconfig /flushdns, but It's not changing anything.

    - by OckhamsRazor
    I know that this question sounds stupid, but over all these years, I still have difficulty explaining TCP/IP to people. I don't completely get it myself, and even after reading up on it, the distinction is not very clear. What I get so far is that IP deals with networks while TCP involves delivery of messages over that network. I'm not totally convinced though. Also, they reside on different layers of the Internet architecture. Could anyone disambiguate this distinction using a simple analogy or examples? Also, I read this somewhere The difference is that TCP is responsible for the data delivery of a packet and IP is responsible for the logical addressing. In other words, IP obtains the address and TCP guarantees delivery of data to that address. Is this correct? Thanks for helping me out. One last thing- Where does the ethernet come in all of this?

  • Routing WIFI and LAN for specific traffic

    - by jakebird451
    I have two network devices aboard my macbook pro: WIFI (en1): Used for general traffic. Connects to an ip of 192.168.19.* via DHCP LAN (en0): Used for specific traffic. Connects to an ip of 192.168.2.10 as a static IP. Does not connect to a router, only a switch for direct routing connection. I have 4 IP addresses I need to access on the LAN: 192.168.2.1 192.168.2.21 192.168.2.20 192.168.2.30 The rest of the traffic needs to go to WIFI. I have tried setting up a routing table for the specific ip addresses, but I only managed to mess up my network. I do not venture out into the world of networking too often, but this was the latest command I have been trying: sudo route add -host 192.168.2.30 -interface en0 This command killed my ability to use ping. It told me that ping could not allocate memory (is that even possible)? It also killed my wifi access. Logging out and back in fixed the issue. I really do not mind to make this solution permanent, so I am fine with a temporary routing. EDIT: If I currently have been trying: sudo route flush sudo route add default 192.168.19.1 This gets everything to work for about a minute. But after such minute it "forgets" the routing to WiFi while retaining LAN's (en0) routing. If I unplug and replug my LAN (en0) cable, the process works for another minute.
