Domanda

Ho un'applicazione C# Windows in esecuzione come "Autorità NT Network Service" che deve effettuare una richiesta post su HTTPS al server ospitato su Apache Tomcat. Sto usando HTTPWebRequest per emettere la richiesta. Accetto il certificato del server impostando un delegato di ServicePointManager.ServerCertificateValidationCallback. C'è un lungo ritardo (~ 15 secondi) tra la chiamata a httpwebrequest.getRequestStream () e l'invocazione del callback ServerCertificateValidationCallback.

Quando eseguo lo stesso codice di LocalSystem, funziona bene senza il ritardo. Cosa potrebbe andare storto?

Cose che ho provato finora:

  • Disabilitazione del proxy impostando request.proxy = null e impostando defaultproxy anabled = "false" in app.config
  • Impostazione richiesta.ServicePoint.Expect100Continue = false
  • Impostazione ServicePointManager.CheckCertificateRevocationList = false
  • ServicePointManager.Expect100Continue = false

========================================================================

Niente di tutto ciò sembra funzionare. C'è ancora un ritardo coerente di 15 secondi in httpwebrequest.getRequestStream (). Tracce System.NET raccolte anche.

Codice:

        ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateRemoteCertificate);

        ServicePointManager.Expect100Continue = false;

        ServicePointManager.CheckCertificateRevocationList = false;





   public static bool ValidateRemoteCertificate( object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors policyErrors)

    {

        Trace.TraceInformation("HttpWebClient.ValidateRemoteCertificate: Implicitly allowing SSL certificate");

        return true;

    }

Client Web:

        HttpWebRequest request = (HttpWebRequest) HttpWebRequest.Create(uri);

        request.KeepAlive = false;

        request.ProtocolVersion = HttpVersion.Version11;

        request.Method = "POST";

        request.Proxy = null;

        request.AuthenticationLevel = AuthenticationLevel.None;

        request.AllowWriteStreamBuffering = false;

        request.ServicePoint.Expect100Continue = false;



        byte[] postBytes = Encoding.ASCII.GetBytes(post_data);



        request.ContentType = "application/x-www-form-urlencoded";

        request.ContentLength = postBytes.Length;



        try

        {

            Stream requestStream = request.GetRequestStream();



            Trace.TraceInformation("HttpWebClient.SendRequest Sending request of length {0}...", postBytes.Length);

            requestStream.Write(postBytes, 0, postBytes.Length);

            Trace.TraceInformation("HttpWebClient.SendRequest Request sent");

            requestStream.Close();

        }

        catch (Exception e)

        {

            Trace.TraceInformation("HttpWebClient.sendRequest: exception {0}, {1}", e.Message, e.StackTrace);

        }



        Trace.TraceInformation("HttpWebClient.SendRequest Fetching HTTP response...");

        HttpWebResponse response;

        response = (HttpWebResponse)request.GetResponse();

System.net Traces: Dalle tracce, il ritardo di 15 sec è dal 2011-09-07T21: 42: 16.7796885Z al 2011-09-07T21: 42: 31.7897095Z. Gli errori segnalati sono: Certificato remoto presenta errori:, Nome certificato Mismatch., Una catena di certificato elaborata, ma terminata in un certificato di root che non è affidabile dal fornitore di fiducia.

Nessuna soluzione corretta

Altri suggerimenti

Finalmente ho trovato la causa principale. Ecco qui:

Durante la connessione SSL, Windows Update viene invocato per aggiornare i certificati di root. Questo ha bisogno di una connessione Internet. Se la macchina è connessa a Internet, non verrà visualizzato alcun ritardo. Se la macchina non è connessa a Internet, viene visualizzato un ritardo di 15 secondi perché è il valore di timeout predefinito per il recupero di rete dei certificati di root aggiornati.

Questo è secondo il design e non un bug secondo il seguente articolo KB di Microsoft.http://support.microsoft.com/kb/317541

Ho riscontrato un problema simile con un server senza accesso a Internet. La soluzione era di disabilitare gli aggiornamenti automatici di root e ridurre il timeout per l'elenco CRL a un secondo.
Per farlo.

Start Gpedit.msc -> Politica del computer locale -> Configurazione del computer -> Modelli amministrativi -> Sistema -> Gestione comunicazioni Internet -> Impostazioni di comunicazione Internet -> disattivare l'aggiornamento del certificato root automatico = abilitato

E

AVVIO GPEPETIT.MSC -> Politica del computer locale -> Configurazione del computer -> Impostazioni Windows -> Impostazioni di sicurezza -> Politica della chiave pubblica -> Percorso di convalida del percorso del certificato. Seleziona la scheda "Recupero di rete" e abilita "Defini queste impostazioni della politica". Deselezionare "Root di aggiornamento automatico ..." E il più importante impostare i valori di timeout su 1.

Il ritardo è visibile nei registri di rete ...

a questo:

0412] SecureChannel#46104728 - Il certificato remoto è stato verificato come valido dall'utente.**

È possibile che nell'account NetworkService, le tue impostazioni proxy ecc. Non siano configurate correttamente, quindi Schannel non può ottenere l'elenco di revoca del certificato e fare altre cose (come camminare sulla catena del certificato di root) per convalidare rapidamente il certificato?

Quando si esegue come NetworkService, fai un fiuto di rete usando WireShark. Questo ti mostrerà cosa sta succedendo. Naturalmente sarà incomprensibile a causa di SSL, ma dovresti almeno essere in grado di vedere le richieste HTTP in uscita in uscita per il CRL e i certificati root.
