Hi, $ nc -zvc openbsd.org 443 # works as expected Connection to openbsd.org (129.128.5.194) 443 port [tcp/https] succeeded! TLS handshake negotiated TLSv1.3/AEAD-AES256-GCM-SHA384 with host openbsd.org [...]
$ nc -zvc openbsd.org. 443 # fails Connection to openbsd.org. (129.128.5.194) 443 port [tcp/https] succeeded! nc: tls handshake failed (handshake failed: error:1404B42E:SSL routines:ST_CONNECT:tlsv1 alert protocol version) And FWIW I get a different error when the destination runs nginx: $ nc -zvc px.chown.me. 443 Connection to px.chown.me. (198.48.202.221) 443 port [tcp/https] succeeded! nc: tls handshake failed (handshake failed: error:1404B417:SSL routines:ST_CONNECT:sslv3 alert illegal parameter) I checked with -Tnoname to be sure, and it didn't change anything. Is that normal? Cheers, Daniel
