Now the example runs: $ ruby drbssl_c.rb foo [false, "unable to get local issuer certificate"] [false, "certificate not trusted"] [false, "unable to verify the first certificate"] "Hello, foo." bar "Hello, bar." zap "Hello, zap." (There is no output on the server side.) I'm a little worried about those messages. Do I have to generate some site certificates myself? It looks like the server is using the "sample.key" and "sample.crt" certificate. (I'm an ssl newbie.) Thanks again for all your help!
