How can a C# client app list the authorized CA certificates sent by a web server over an SSL connect

Posted By:      Posted Date: September 09, 2010    Points: 0   Category :.NET Framework
Hello, I am currently writting a C# client application that must access a web page over SSL authentication, having the Client authentication required. I know that the SSL protocol defines that the web server sends the list of authorized Certification Authority that the web server can trust for the SLL session to be successful. My client application has to filter a X509Certificate collection in order to popup a Certificate Selection dialog box to the user. I fould like to only display certificates that the web server would accept. I already have filtered the certificates according to the "Client Authentication" Enhanced Key Usage and other stuf. I know how to set the client certificate to be used for SLL conection, but I just would like to access the CA cert list provided by the server.   Could someone help me ? Thanks a lot !

Unable to connect to SQL Server 2005 remotly, all client protocols are blank

I have an installation of SQL 2005 and had issues connecting remotly. Looking at the client protocolols, they are all blank. I can see that TCPIP, Named Pipes, VIA, etc. are 'enabled', but where the words 'TCPIP', 'Names Pipes', etc. should be, it's just blank. I tried to install SQL 2008R hoping the Client Protocols would be corrected during the installaion, but they were not. I'm assuming the issue with the Client Protocols not showing up is a symptom of the problem. Does anyone have any ideas? Thanks!

Client using OpenSSL is not able to connect to Server using SslStream.


I have been trying to get a client written in C++ using OpenSSL 0.9.8a to connect successfully with a server written in C# using the SslStream class in .NET 4.0.  Thus far, I have been not able to get the client to successfully connect and communicate even when my server does not require a client certificate from the client.

I am getting always the following IOException " The handshake failed due to an unexpected packet format. " when i am reaching the AuthenticateAsServe() line in my server.

Any help will be highly appreciated.

how to connect my RTC client to server, if i'm firewalled?


hello everybody,

so i try to explain in short what is the problem.

My OS is WinXP SP2, and my computer ir firewalled from outside, i'm running Microsoft Firewall Client for ISA server.

My RTC client connects to the server over SIP protocol, registering, and after it is registered i can make calls such like PC-to-PHONE. The source of my RTC client you can find there: http://ausroma.projektas.lt/temp/Source.txt

it works fine when i connect to PBX sip server which is in our internal network, but i can't connect when i try to connect to the server which is outside firewall....

i have another SIP client (X-Lite): http://ausroma.projektas.lt/temp/x-lite.JPG and it works fine (register succesfully) when ISA firewall is enabled on my PC (when i disable ISA this client can't connect and i have registering time-out). I sniffed some packets, when ISA is enabled, and x-lite client connects succesfully: http://ausroma.projektas.lt/temp/xlite_sniff.JPG how we can see, there is sending requests, and we recieve respons

Hey all, so here's what going on:

I have a WCF Service that I have setup as a Windows Service.  Everything works perfectly when I attempt to use the system with all of the components (i.e. server and clients) on the same machine.  However, when I try to connect my client from a different system, I get an error that is trying to tell me that the server rejected the client's credentials.

I need the client to the able to connect from a different machine.  I want to implement a SQL Role Provider kind of credentialing in the future, but for now, I just need it to work.

What I have tried
I have looked around online and read a few other posts as well some things in the MSDN KB and I have either not found the answer, or not understood it.

  • I have tried setting the <security mode="Transport"> to "None" with the hope that that would disable the accreditation entirely.  All it did was result in a different error saying that there was an error that might have been caused by an invalid message.  I have also tried a few other configurations with this element in the app.config file; to no success.
  • I have read some things about Impersonation, but I am not quite sure I understand how to implement it

Custom client app cannot connect to SQL server 2008



We have a custom application developed using Access 2003 but converted to 2007 which connects to database SQL server 2008 converted from 2005. Users are unable to connect via application and get the following error.  Application uses ADO.NET to connect. But when Network library configuration and enable TCP/IP protocol with servername and portno using SQL Server Network Utility setup (cliconfg), It works fine. We have about 150 users but it is complicated to do for each users.

Also users uses windows authentication to connect. They belong to one of the three Windows Active Directory groups which are given RW permission on the database side.

Client can't connect to WCF on deployment machine Windows 2003 Sp2 server .NET 3.5



I have a WCF service hosted in a Windows service application.  I have a Windows Form client that connects to it.  I am using net.tcp binding for two endpoints.   It all works fine in my environment, but when I deploy it on my cutomer's machine the client does not get a response from the service.

I ran netstat -na and I can see the endpoints listening.  I can even see the connection ESTABLISHED when my client runs the first method.  But my client times out and receives a "Could not communicate with XXX service.  This request operation sent to net.tcp..... did not receive a reply within the configured timeout (00.01.00) The time alloted... etc"

I tried removing all security from the configuration file, but that did not make a difference.

I reinstalled .NET Framework 3.5

I added     System.Net.ServicePointManager.DefaultConnectionLimit = 200 as suggested in another post.

I am creating a trace for the client and the server.  The server does not log any activity of a connection.  The client is catching a communication exception.

Any insight would be greatly appreciated.  What else can I try to see why the client is not able to chake hands with the server on this particular machine?

Many thanks,

SOAP: Using ATL Server to Build an Asynchronous SOAP Client in Unmanaged C++


SOAP opens up a new world of Web Services, letting you make function calls across a network or the Internet. But this flexibility creates new problems when your app needs to wait for calls to return from halfway around the world. What you need is an asynchronous SOAP client that takes advantage of threading to continue execution while waiting for calls over the wire. This article covers the basics of building such a client with ATL.

TSQL: Passing array/list/set to stored procedure (MS SQL Server)

Passing array/list/set to stored procedure is fairly common task when you are working with Databases. You can meet this when you want to filter some collection. Other case - it can be an import into database from extern sources. I will consider few solutions: creation of sql-query at server code, put set of parameters to sql stored procedure's parameter with next variants: parameters separated by comma, bulk insert, and at last table-valued parameters (it is most interesting approach, which we can use from MS SQL Server 2008). Ok, let's suppose that we have list of items and we need to filter this items by categories ("TV", "TV game device", "DVD-player") and by firms ("Firm 1", "Firm2", "Firm 3). It will look at database like this So we need a query which will return us list of items from database. Also we need opportunity to filter these items by categories or by firms. We will filter them by identifiers. Ok, we know the mission. How we will solve it? Most easy way, used by junior developers - it is creating SQL-instruction with C# code, it can be like this List<int> categories = new List<int>() { 1, 2, 3 };   StringBuilder sbSql = new StringBuilder(); sbSql.Append( @" select i.Name as ItemName, f.Name as FirmName, c.Name as CategoryName from Item i inner join Firm f on i.FirmId =

Educational question: How server objects are accessed from multiple client threads?

I will appreciate it if someone can help me to undestand how the following scenario works:   There is remoting server that is registered as WellKnownObjectMode.Singleton.
