    <p>I am trying to create a simple SSL client and server in Ruby. But I'm getting a cryptic error message and the documentation is of no help.</p> <p>Here is my server code:</p> <pre><code>#!/usr/bin/ruby require "gserver" require "openssl" listeningPort = Integer(ARGV[0]) class Server &lt; GServer def initialize(listeningPort) @sslContext = OpenSSL::SSL::SSLContext.new @sslContext.cert = OpenSSL::X509::Certificate.new(File.open("MyCert.pem")) super(listeningPort, "0.0.0.0") end def serve(io) begin ssl = OpenSSL::SSL::SSLSocket.new(io, @sslContext) ssl.sync_close = true ssl.connect while (lineIn = ssl.gets) lineIn = lineIn.chomp $stdout.puts "=&gt; " + lineIn lineOut = "You said: " + lineIn $stdout.puts "&lt;= " + lineOut ssl.puts lineOut end rescue $stderr.puts $! end end end server = Server.new(listeningPort) server.start server.join </code></pre> <p>The client code is similar:</p> <pre><code>#!/usr/bin/ruby require "socket" require "thread" require "openssl" host = ARGV[0] port = Integer(ARGV[1]) socket = TCPSocket.new(host, port) sslContext = OpenSSL::SSL::SSLContext.new sslContext.cert = OpenSSL::X509::Certificate.new(File.open("MyCert.pem")) ssl = OpenSSL::SSL::SSLSocket.new(socket, sslContext) ssl.sync_close = true ssl.connect puts ssl.peer_cert # this is nil Thread.new { begin while lineIn = ssl.gets lineIn = lineIn.chomp $stdout.puts lineIn end rescue $stderr.puts "Error in input loop: " + $! end } while (lineOut = $stdin.gets) lineOut = lineOut.chomp ssl.puts lineOut end </code></pre> <p>When I connect, I get this error on both the server and the client:</p> <pre><code>in `connect': SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol (OpenSSL::SSL::SSLError) </code></pre> <p>The problem could be that it doesn't trust the certificate (self-signed). I'm not sure how to tell the client to trust that certificate. Above, I have put the server's cert in the context, but that was just a shot in the dark. I'm not even sure my certificate is in an acceptable format (it is in base64 with the cert and the private key in the file). The documentation is very scant and there doesn't seem to be much on the web in this area either. </p> <p>Any ideas?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
