    这是一个创建于 3648 天前的主题,其中的信息可能已经有所发展或是发生改变。
    wget(1.11.4) --ca-certificate=$myhttpca https://nodejs.org/dist/v5.3.0/node-v5.3.0-linux-x64.tar.gz 

    其中 $myhttpca 文件来之 https://github.com/bagder/ca-bundle/blob/master/ca-bundle.crt 的至今最新版。
    出现 一下错误

    Resolving nodejs.org... 104.20.22.46, 104.20.23.46, 2400:cb00:2048:1::6814:162e, ... Connecting to nodejs.org|104.20.22.46|:443... connected. ERROR: certificate common name `*.nodejs.org' doesn't match requested host name `nodejs.org'. To connect to nodejs.org insecurely, use `--no-check-certificate'. Unable to establish SSL connection. 

    而但我转到另外一台比较新的服务器, wget 时(版本 1.12 ,不需要用 ca 文件),则没有出错。

    已经纠结了一个下午,不太懂 SSL 认证的原理,感觉是 wget 版本的原因,在旧服务器(上面),上直接 wget --ca.... https://github.com/... 的文件是不会出错的。只要 https 服务端的 ip 有变化就会出问题了。望解释,太纠结了谢谢大家!

    Thx all.

    刚刚在旧服务器上编译了一个跟 新服务器上版本一样的 wget 1.12 ,一样./wget 不了 https://nodejs.org/en/
    提示信息跟原先 1.11.4 那个版本一样,因此猜想不是由于 wget 的原因造成的。

    感觉 openssl 的版本也有关系,附上。

    旧服务器:很老对不对
    OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

    新服务器:
    OpenSSL 1.0.1e-fips 11 Feb 2013

    看了一下 nodejs 服务器的证书,应该是你的服务器不支持 X509v3 Subject Alternative Name 引起的问题。

    服务器证书有
    X509v3 Subject Alternative Name:
    DNS:*.nodejs.org, DNS:nodejs.org

    你的 wget 不认 引起了问题

    PS: 使用命令
    openssl s_client -connect nodejs.org:443 -showcerts | openssl x509 -noout -text
    可以查看服务器证书

    可能是 SNI 导致的: https://en.wikipedia.org/wiki/Server_Name_Indication

    很多老版本的 HTTP 工具 /库不支持 SNI

    @zealot0630 Thx 。我用你给的命令查看了一下,但我不会看这个结果。但是我看到了 X509v3 Subject Alternative Name: 关键词输出,想必是服务器支持 SAN 的

    @znlab ,非常好的提示,谢谢。
    我的老服务器上的 wget ( open ssl 0.9.8e; SNI 是 0.9.8f 才支持)是不支持 SNI 的,本来还真以为我现在出现 wget 不了就是 SNI 这个原因。
    后来在新服务器上 同样 wget https://sni.velox.ch/ ;结果都是不支持 SNI 的。从你给的 wiki 也可知 wget before 1.14 是不支持 SNI 的,因此 两个服务器上的 wget 都是不支持 SNI 的;但根据 openssl 的版本给的信息,新服务器上 OpenSSL 1.0.1e-fips 11 Feb 2013 支持 SNI ;

    现在问题就是是不是由于 wget 支不支持 SNI 与 openssl 支不支持 SNI 之间的配合,而造成了我 题本 中出现的问题呢?又感觉好像不是 SNI 的问题,还有可能有其他的方向嘛?可否给点方向就好。非常感谢!

    @ekeyme nodejs 服务器根本就没配置 SNI 你的客户端也不需要支持 SNI

    是你老版本的 wget 不支持 X509v3 Subject Alternative Name 引起的异常
