SQL Server Pre-Login Handshake

I'm connecting to MSSQL database through my ASP .NET application, but sometimes I got this error while opening connection. Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=3; handshake=14996; To solve it temporarily I've to restart IIS. I'm using this code snippet to connect to MSSQL: using (SqlConnection connection = new

Java 7 (acting as client) SSL handshake failure with keystore and truststore that worked in Java 6

问题 I'm doing a JBoss AS 5.1 to 7.4, and Java 6 to 7 migration, and get a handshake failure. The keystore and truststore are the ones we have been using successfully for ages with Java 6. I've written some tests to narrow the problem down, it's definitely not JBoss but rather Java 7. With SSL logging turned on, I get this: 17:44:30,041 INFO [stdout] (http-/192.168.147.20:8080-120) %% Invalidated: [Session-2, SSL_RSA_WITH_RC4_128_SHA] 17:44:30,041 INFO [stdout] (http-/192.168.147.20:8080-120) http

Websocket Handshake Failed In Java

跟風遠走 提交于 2019-12-03 09:04:47
So, I'm trying to parse a website which uses websocket to send data to clients. From what I've read: Link 1 Link 2 I understood that for creating a connection, I need to send a special http request to server and ot will retrieve some data which i use to access the channel. What I've done: created the http request `URL obj = new URL(url); HttpURLConnection con = (HttpURLConnection) obj.openConnection(); // optional default is GET con.setRequestMethod("GET"); //add request header con.setRequestProperty("Cache-Control", "no-cache"); con.setRequestProperty("Host", "www.example.com"); con

wpa-handshake with python - hashing difficulties

匆匆过客 提交于 2019-12-03 07:27:31
I try to write a Python program which calculates the WPA-handshake, but I have problems with the hashes. For comparison I installed cowpatty (to see where I start beeing wrong) . My PMK-generation works fine, but the PTK-calculation alsways seems to be wrong. I am not sure if I have to format my input (macadresses and noces) or just give them into the function as a string. I will give you my routerinformation, which is no problem since I just set it up for testing. My program looks as follows: import hmac,hashlib,binascii passPhrase = "10zZz10ZZzZ" ssid = "Netgear 2/158" A = "Pairwise key

Handshake alert: unrecognized_name error

I am using Charles 3.7 to debug SSL connections. I was able to view most of the HTTPS connections, however there is 1 or 2 sites that returned "SSLProtocol: handshake alert: unrecognized_name" when I try to debug it, and I was unable to load the website with Charles on. I am able to do so using Fiddler. Any ideas on how to resolve this issue? Thanks. I came across this when using the latest beta Charles 3.10b9 on 10.10. We fixed by using a similar method to Shade's answer: I opened info.plist in Xcode and did the following: Under the JVMOptions (as oppose to VMOptions) key add the string:

How to get current cipher in pyOpenSSL for DTLS

半腔热情 提交于 2019-12-02 08:04:29
问题 I need to get a negotiated cipher for DTLS protocol in pyOpenSSL. I was successful in doing that for TCP sockets, but when it comes to datagrams, it's not that obvious. Please provide an example either in C or Python. This is what I've tried so far: import socket from OpenSSL import SSL from OpenSSL._util import ( ffi as _ffi, lib as _lib) DTLSv1_METHOD = 7 SSL.Context._methods[DTLSv1_METHOD]=getattr(_lib, "DTLSv1_client_method") ctx = SSL.Context(DTLSv1_METHOD) ctx.set_cipher_list('AES128
