Hello Stanislas,

I tried the below command but it just shows me SSL errors. Can you assist?


(echo -ne "GET / HTTP/1.1\\r\\nHost: abc.com\\r\\nConnection: Close\\r\\n"; cat) | openssl s_client -connect 1.1.1.1:443 -quiet

47753692343424:error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure:s3_pkt.c:1293:SSL alert number 40 47753692343424:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:184:

It shows me the above errors after being connected.

Note: I do not have a DNS entry for abc.com in place

Regards,

Ajit
