openssl握手失败

我正在尝试编写简单的C openssl客户端和服务器。下面是客户端的代码：openssl握手失败

int main() { 
    int err; 

    SSL_CTX * ctx = init_ctx("client-cert.pem", "client-private.pem", "certs/cacert.pem", "clientpass"); 
    if (!ctx) { 
     fprintf(stderr, "couldn't init ctx\n"); 
     exit(1); 
    } 

    int sock = tcp_connect("localhost", 4443); 

    /* Connect the SSL socket */ 
    SSL * ssl = SSL_new(ctx); 
    BIO * sbio = BIO_new_socket(sock,BIO_NOCLOSE); 
    SSL_set_bio(ssl,sbio,sbio); 

    if((err = SSL_connect(ssl)) != 1) { 
     switch(SSL_get_error(ssl, err)) { 
      case SSL_ERROR_NONE: 
      fprintf(stderr, "error SSL_ERROR_NONE\n"); 
      break; 
      case SSL_ERROR_ZERO_RETURN: 
      fprintf(stderr, "errorSSL_ERROR_ZERO_RETURN \n"); 
      break; 
      case SSL_ERROR_WANT_READ: 
      fprintf(stderr, "error SSL_ERROR_WANT_READ\n"); 
      break; 
      case SSL_ERROR_WANT_WRITE: 
      fprintf(stderr, "error SSL_ERROR_WANT_WRITE\n"); 
      break; 
      case SSL_ERROR_WANT_CONNECT: 
      fprintf(stderr, "error SSL_ERROR_WANT_CONNECT\n"); 
      break; 
      case SSL_ERROR_WANT_X509_LOOKUP: 
      fprintf(stderr, "error SSL_ERROR_WANT_X509_LOOKUP\n"); 
      break; 
      case SSL_ERROR_SYSCALL: 
      fprintf(stderr, "error SSL_ERROR_SYSCALL\n"); 
      break; 
      case SSL_ERROR_SSL: 
      fprintf(stderr, "error SSL_ERROR_SSL\n"); 
      break; 
      default: 
      fprintf(stderr, "error f****** s***!!!\n"); 
      break; 
     } 
     fprintf(stderr, "%s\n", ERR_error_string(ERR_get_error(), NULL)); 
     ERR_print_errors_fp(stderr); 
     //exit(1); 
    } 

    check_cert(ssl, "host.com"); 
    fprintf(stderr, "%d bytes sent\n", send_request(ssl, "come with me, we'll go dreaming")); 

    /* shutdown ssl connection */ 
    err = SSL_shutdown(ssl); 
    if (err < 0) { 
     ERR_print_errors_fp(stderr); 
     exit(1); 
    } 

    close(sock); 
    SSL_free(ssl); 
    SSL_CTX_free(ctx); 

    return 0; 
} 

ssize_t send_request(SSL * ssl, const char * req) { 
    fprintf(stderr, "sending request...\n"); 
    ssize_t size = SSL_write(ssl, req, strlen(req)); 

    if (size < 0) { 
     ERR_print_errors_fp(stderr); 
    } 

    return size; 
}

SSL_get_error(ssl, err)回报SSL_ERROR_SYSCALL和以下错误send_request回报：5269:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188:。有密码保护的私钥，我设置pem_password_cb回调：

SSL_CTX_set_default_passwd_cb(ctx, passwd_func); 
SSL_CTX_set_default_passwd_cb_userdata(ctx, (void *)password);

。使用V23的方法......我不知道这个握手的原因失败...

我试着调试这样的方式：openssl s_client -connect localhost:4443 -cert sberbank-cert.pem -key sberbank-private.pem -verify 1 -CAfile cacert.pem -prexit -msg和我有以下结果：

[email protected]:~/src/tests/ssl$ openssl s_client -connect localhost:4443 -cert sberbank-cert.pem -key sberbank-private.pem -verify 1 -CAfile cacert.pem -prexit -msg

这里tcp_connect的来源。我敢肯定，这不是失败，因为它返回的fd（不-1）：

int tcp_connect(const char *host, int port) { 
    struct hostent *hp; 
    struct sockaddr_in addr; 
    int sock; 

    if(!(hp=gethostbyname(host))) 
     return -1; 

    memset(&addr,0,sizeof(addr)); 
    addr.sin_addr=*(struct in_addr*) 
    hp->h_addr_list[0]; 
    addr.sin_family=AF_INET; 
    addr.sin_port=htons(port); 

    if((sock=socket(AF_INET,SOCK_STREAM, IPPROTO_TCP))<0) 
     return -1; 

    if(connect(sock,(struct sockaddr *)&addr, sizeof(addr))<0) 
     return -1; 

    return sock; 
}

如果你的'connect'已经失败，那么'send_request'也会失败。 man'SSL_ERROR_SYSCALL 发生了一些I/O错误。 OpenSSL错误队列可能包含有关错误的更多信息。如果错误队列为空（即ERR_get_error（）返回0），ret可用于找出更多关于错误的信息：如果ret == 0，则观察到EOF违反协议。如果ret == -1，底层的BIO报告了一个I/O错误（对于Unix系统上的套接字I/O，请参考errno获取详细信息）。“你做过了吗？ – RedX 2011-06-07 10:03:15

你确定'tcp_connect（）'永远不会失败吗？ – 2011-06-07 10:30:06

'tcp_connect'不会失败，它会返回套接字的fd。并且服务器响应它有传入连接。 – milo 2011-06-07 10:34:07

我已经解决了我的问题！它不是客户端，而是服务器端！服务器关闭tcp连接，同时获取重复SSL_accept的SSL_WANT_READ错误。感谢参与！
