Hi, We are trying to use a Cavium H/W SSL acceleration card to accelerate SSL encryption. The Cavium driver builds and installs without complaint. Cavium supplies an SDK for building libcrypto.a and libssl.a. These too built without issue. We compiled Squid 3.1.0.4 statically using the Cavium supplied libraries and the configuration options: "--with-openssl=<cavium-base-directory>" and " --enable-ssl". (We used ldd to confirm that Squid built statically with the correct libraries.) In our squid.conf file we added "ssl_engine cavium" as per information provided by Cavium; but, we get the message: FATAL Unable to find SSL engine 'cavium'. Cavium has tested with Apache but never with Squid. Questions: 1) Does Squid require a patch for SSL crypto h/w acceleration? 2) Are there any Squid settings I need to know about? 3) Has anyone been successful with another h/w card? We are not wedded to Cavium. Forgive me if this territory has been covered in the past; I'm new to Squid. Thank you in advance for any help, Steven Paster FaceTime Communications
