It’s easy to telnet to port 80 on a “standard” non-SSL webserver, and issue a GET / in order to verify that the webserver is responding correctly. But how to do it over SSL? Just use the s_client command via the openssl tool.

# openssl s_client -connect www.example.com:443 |
You’ll see details of the certificate chain displayed (as well as any errors), and you can then issue your
GET / to test the webservers operation.
You can also use this tool to test other SSL-enabled services (such as IMAPS/POP3S).
