    [root@CCNWEB18 ~]# telnet 59.162.59.204 443
Trying 59.162.59.204...
Connected to 59.162.59.204 (59.162.59.204).
Escape character is '^]'.

    [root@CCNWEB18 ~]# curl https://59.162.59.204/
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). The default
bundle is named curl-ca-bundle.crt; you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.

这样算成功嘛？但我在图形页面是可以正常访问https://59.162.59.204/这个地址的。

    非常感谢，其实我知道对方是开着443端口的，但由于我们公司有防火墙，管理防火墙的人说已经打开我们内部一台服务器访问59.162.59.204 443端口。
我想测试一下到底是不是可以访问？？？
