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。
