I'm trying to resolve an issue I am facing at the moment with the latest nrpe 3.2.1 running on Solaris 11.
When nessus scans, it complains that nrpe is using SSL Medium Strength Cipher suites (SWEET32) , ADH-DES-CBC3-SHA Enc=3des-CBC(168) Mac=sha1. Openssl version 102R. How do I turn off this Cipher ? Also, any tools to actually list the ciphers nrpe is accepting ? (remote tool or local tool)

Thanks

Hi @ebuttice,

For your options with regard to configuring SSL, you'll want to look at the NRPE SSL Readme. If you want to allow/disallow specific ciphers, you'll need to determine that using the ssl_cipher_list directive in nrpe.cfg. You can check the ciphers by checking that file.
