$ openssl s_client -tls1_2 -connect 172.11.15.32:443 </dev/null | grep 'IS s'
depth=0 C = US, ST = asd, O = Billing, CN = asdasd, emailAddress = root@asdasd
verify error:num=18:self signed certificate
verify return:1
depth=0 C = US, ST = asd, O = Billing, CN = asdasd, emailAddress = root@asdasd
verify return:1
DONE
Secure Renegotiation IS supported

然而,问题是,无论我的grep是什么,输出始终包含这些(或类似的)行:

depth=0 C = US, ST = asd, O = Billing, CN = asdasd, emailAddress = root@asdasd
    verify error:num=18:self signed certificate
    verify …
