I have installed Ubuntu 16.04 LTS on my laptop for my testing. Connect to gmail.com using the following command.
openssl s_client -connect gmail.com:443 -ssl3
But I get the following error:
139903184385688:error:140A90C4:SSL routines:SSL_CTX_new:null ssl method passed:ssl_lib.c:1878
Question:
Am I missing any libraries to install? Or -ssl3 option is now not supported with openssl 1.0.2g-1ubuntu4.1?
