I’m trying to set up DRb over SSL, following the guide at  
[http://segment7.net/projects/ruby/drb/DRbSSL/](http://segment7.net/projects/ruby/drb/DRbSSL/). When I create the  
DRbObject though, I get the error “drbssl://localhost:1111 -  
#\<OpenSSL::SSL::SSLError: unknown protocol\>”

I’m requiring drb and drb/ssl, and you can see the connection string  
I’m using. What’s wrong with this?

Okay I’ve gotten past that error. Now I’m getting  
“drbssl://localhost:1111 - #\<OpenSSL::SSL::SSLError: sslv3 alert  
unsupported certificate\>”

My config for the server is  
config = {  
:SSLVerifyMode =\> OpenSSL::SSL::VERIFY\_PEER |  
OpenSSL::SSL::VERIFY\_FAIL\_IF\_NO\_PEER\_CERT,  
:SSLPrivateKey =\>  
OpenSSL::PKey::RSA.new(File.read(“specs/certs/localhost/localhost\_keypair.pem”)),  
:SSLCertificate =\>  
OpenSSL::X509::Certificate.new(File.read(“specs/certs/localhost/cert\_localhost.pem”)),  
:SSLCACertificateFile =\> “specs/certs/CA/cacert.pem”  
}

and my config for the client is  
config = {  
:SSLVerifyMode =\> OpenSSL::SSL::VERIFY\_PEER,  
:SSLCACertificateFile =\> (“specs/certs/CA/cacert.pem”),  
:SSLPrivateKey =\>  
OpenSSL::PKey::RSA.new(File.read(“specs/certs/username/username\_keypair.pem”)),  
:SSLCertificate =\>  
OpenSSL::X509::Certificate.new(File.read(“specs/certs/username/cert\_username.pem”))  
}

It prompts me for the password when I create the server. Then it  
gives me that “unsupported certificate error” when I try to make a  
remote call. Any ideas?
