centos6.x 使用wget或者curl時(shí)，無(wú)法請(qǐng)求https下的資源？

簡(jiǎn)而言之就是，凡需要請(qǐng)求443，就會(huì)出現(xiàn)問(wèn)題。

請(qǐng)求例如wget http://www.acfun.cn是順利執(zhí)行的。

于是我查了一下B的openssl

[root@AY140220152843902sdg46ZsG ~]# openssl version -a
OpenSSL 1.0.1e-fips 11 Feb 2013
built on: Wed Mar 22 21:43:28 UTC 2017

雖然版本很久，但是根據(jù)built on來(lái)看，是有更新的吧。

順便附上iptables，我唯一能想到可能關(guān)聯(lián)的。
