how to determine cipher list?
What commands can I run against my webserver to determine what ciphers he is accepting? Is this possible with some type of openssl command?
Thank you,

Hi,
The OpenSSL program does not offer the output you're looking for. Convenient solutions to your problem include
1) Using a BASH/PYTHON/PERL script which executes an OpenSSL command that tries to establish an SSL session with specific cipher suite, one after another.
2) Online SSL checker, e.g. https://www.ssllabs.com/ssltest/index.html - this will print out the SSL/TLS versions and cipher suites which are accepted by the webserver (does the exact same thing as 1). Only suitable for publicly open HTTPS services, alternatively you can create an IP whitelist for Qualys lab tools. - John_Ogle_45372

Good infno. I will need to attempt the script from the LTM since this box is in a secure zone and cannot be accessed from the internet to use a tool like ssllabs, etc.
thank you,
