尝试通过 SSL 连接到 xmpp 服务器时,openssl 失败并出现以下错误:3071833836:错误:140790E5:SSL 例程:SSL23_WRITE:ssl 握手失败:s23_lib.c:177
我相信服务器使用 RC4-MD5 密码,这里是完整的输出:
[root@localhost ~]# openssl s_client -connect 184.106.52.124:5222 -cipher RC4-MD5

使用 gnutls-cli:
[root@localhost ~]# gnutls-cli 184.106.52.124 -p 5222
Resolving '184.106.52.124'...
Connecting to '184.106.52.124:5222'...
*** Fatal error: A TLS packet with unexpected length was received.
*** Handshake has failed
GNUTLS ERROR: A TLS packet with unexpected length was received.
通过端口 5223 连接到同一台服务器可以正常工作。
在 CentOS 6.5 上使用 OpenSSL 1.0.1e-fips,在 Ubuntu 14.04.1 上使用 OpenSSL 1.0.1f
有什么方法可以解决这个问题吗?提前谢谢您。

从您目前发布的内容来看,听起来有点像监听端口 5222 的进程未使用 SSL。作为诊断,也许可以尝试此处的答案:
https://serverfault.com/questions/37699/how-to-check-if-a-server-support-xmpp-protocol/37722#37722
此外,从这里来看:https://stackoverflow.com/questions/3452161/which-ports-does-xmpp-use,端口 5222 上的连接通常不受 SSL 保护(请参阅 RFC 3920,附录 D1)。
