Protocol Problem

[Ertel, Holger]

Hi, I’m a newbie in OpenSSL. I wrote me a SSLClient and a SSLServer for testing OpenSSL under Window2K. I’m using winsockets. My problem is, when I send the SSL Hello message to the server (with SSL_connect) I get an error (SSL_ERROR_SSL). The errorcode says me, that’s an protocol error. What is wrong on my code?   Client:   struct sockaddr_in  port;  /* server's address information */             bool res = false;               m_Sock = (SOCKET)socket (AF_INET, SOCK_STREAM, 0);             if (m_Sock < 0) return -1;               std::string serverIp = "127.0.0.1";             int  portnum  = 16688;               //Hier muss noch das Lesen der Konfiguration rein               m_SSLMethod = SSLv2_client_method();             m_SSLContext = SSL_CTX_new(m_SSLMethod);                         port.sin_family = AF_INET;             port.sin_addr.S_un.S_addr = inet_addr(serverIp.c_str());             port.sin_port = htons(portnum);             memset(&(port.sin_zero),0,8);             if (connect(m_Sock, (struct sockaddr *)&port,sizeof(struct sockaddr)) != 0)                         return -1;             //SSL Verbindung aufbauen             m_SSLConnection = SSL_new(m_SSLContext);                                     if ( !m_SSLConnection )             {                         closesocket(m_Sock);                         return ERR_get_error();             } // if               if (SSL_set_fd(m_SSLConnection,m_Sock))                         printf("Juhu\n");             int err2 = SSL_connect(m_SSLConnection);             if ( err2 < 1)             {                         int err = SSL_get_error(m_SSLConnection,err2);             …       and server:     struct sockaddr_in  sa_serv;              struct sockaddr_in sa_client;             bool res = false;             unsigned int listen_sd;             unsigned int sd;             int client_len;             char buf [4096];               // Winsock version             const int m_iWSVer = 0x00000202;               WSADATA wsaData;             if ( WSAStartup(m_iWSVer,&wsaData) ) return WSAGetLastError();               // Initialize SSL             SSL_load_error_strings();             SSLeay_add_ssl_algorithms();                 listen_sd = (SOCKET)socket (AF_INET, SOCK_STREAM, 0);             if (listen_sd < 0) return -1;               std::string serverIp = "127.0.0.1";             int  portnum  = 16688;               //Hier muss noch das Lesen der Konfiguration rein               SSL_METHOD* pSSLMethod = SSLv2_server_method();             SSL_CTX* pSSLContext = SSL_CTX_new(pSSLMethod);                         sa_serv.sin_family = AF_INET;             sa_serv.sin_addr.S_un.S_addr = inet_addr(serverIp.c_str());             sa_serv.sin_port = htons(portnum);             memset(&(sa_serv.sin_zero),0,8);             if (bind(listen_sd, (struct sockaddr *)&sa_serv,sizeof(struct sockaddr)) != 0)             {                         int err = WSAGetLastError();                         return -1;             }             if (listen(listen_sd,5))                         return -1;             client_len = sizeof(sa_client);             sd = accept(listen_sd,(struct sockaddr *)&sa_client,&client_len);             if (sd < 0) return -1;                         //close(listen_sd);                         //SSL Verbindung aufbauen             SSL* pSSLConnection = SSL_new(pSSLContext);                                     if ( !pSSLConnection )             {                         //closesocket(m_Sock);                         return ERR_get_error();             } // if               if (SSL_set_fd(pSSLConnection,sd))                         printf("Juhu\n");                 //if ( SSL_connect(m_SSLConnection) == -1 )             int err_2 = SSL_accept(pSSLConnection);             if (err_2 < 1)             …..   Thank you for your help.
