我正在尝试将openssl客户端连接到服务器。我正在使用以下命令： openssl s_client -cipher“AES256”-connect 15.213.94.8:6433 -msg
输出是：

为什么会出现ssl3_write_bytes错误和握手失败？
答案 0 :(得分：0)
从日志中可以明显看出，服务器未正确处理第一条消息“ TLS 1.2握手[length 00dd]，ClientHello”，并且未发送 ServerHello 消息，因此它将发送警报通知关闭与客户端的连接。客户端收到警报消息，并调用ssl3_write_bytes处理该消息。并且当前状态仍在TLS重新协商中。因此，将调用握手函数，并发出错误消息，因为预期不会收到消息。这在code
中非常清楚int ssl3_write_bytes(SSL *s, int type, const void *buf_, int len)
{
const unsigned char *buf=buf_;
unsigned int n,nw;
int i,tot;
s->rwstate=SSL_NOTHING;
OPENSSL_assert(s->s3->wnum <= INT_MAX);
tot=s->s3->wnum;
s->s3->wnum=0;
if (SSL_in_init(s) && !s->in_handshake)
{
i=s->handshake_func(s);
if (i < 0) return(i);
if (i == 0)
{
SSLerr(SSL_F_SSL3_WRITE_BYTES,SSL_R_SSL_HANDSHAKE_FAILURE);
return -1;
}
