Hi,

I’m trying to get WEBrick to run a https site but I get the following  
error (it seems after keys have been generated for the cert).

* * *

## root@OpenWrt:/# ruby sslserver.rb [2000-01-06 18:38:03] INFO WEBrick 1.3.1 [2000-01-06 18:38:03] INFO ruby 1.8.5 (2006-08-25) [mips-linux] …++++++ …++++++ /usr/lib/ruby/1.8/webrick/ssl.rb:65:in `create_self_signed_cert': undefined method `create\_extension’ for #OpenSSL::X509::ExtensionFactory:0x2ae594b8 (NoMethodError) from /usr/lib/ruby/1.8/webrick/ssl.rb:106:in `setup_ssl_context' from /usr/lib/ruby/1.8/webrick/ssl.rb:90:in `listen’ from /usr/lib/ruby/1.8/webrick/server.rb:63:in `initialize' from /usr/lib/ruby/1.8/webrick/httpserver.rb:24:in `initialize’ from sslserver.rb:5:in `new’ from sslserver.rb:5

The script is the HTTPS Server example from [http://www.webrick.org/](http://www.webrick.org/) with  
modified DocumentRoot:

* * *

root@OpenWrt:/# cat sslserver.rb  
#!/usr/local/bin/ruby  
require ‘webrick’  
require ‘webrick/https’

## s = WEBrick::HTTPServer.new( :Port =\> 2000, :DocumentRoot =\> “/”, :SSLEnable =\> true, :SSLVerifyClient =\> ::OpenSSL::SSL::VERIFY\_NONE, :SSLCertName =\> [[“C”,“JP”], [“O”,“[WEBrick.Org](http://WEBrick.Org)”], [“CN”, “WWW”] ] ) trap(“INT”){ s.shutdown } s.start

Thank you for any help!

Best, Bjorn
