I have been attempting to implement IMAP authentication in my organization--- it has been nothing but a nightmare. Take this simple function (It''s quick and dirty for testing purposes... definitely a nasty recursive call in there) def authenticate_user(u, p) imap=Net::IMAP.new(''imap.server.net'', 993, true) isvalid = imap.authenticate(''LOGIN'', u, p) return isvalid rescue Errno::ECONNRESET authenticate_user(u, p) rescue false ensure imap.disconnect end On any platform in a flat .rb file: works 100% of the time On Mac OS X in a RoR instance: works 100% of the time On Ubuntu 8.10 (x64 & i386): works, but sometimes throws the Errno::ECONNRESET error which must be rescued On SuSE 10.2 (i386): will not rescue Errno::ECONNRESET error What is going on?! Why do RoR instances on Linux hate Net/IMAP when everything functions fine within Ruby itself or within OS X. There is clearly some kind of issue with OpenSSL, but I''ve tried compiling from source and cross-compiling Ruby on top of it. It should be noted that my OS X box is using 1.8.6 darwin version of Ruby, whereas my Linux servers are using 1.8.7 linux versions. Should I try downgrading Ruby? Any suggestions would be greatly appreciated. Here are more errors for your pleasure: /usr/lib/ruby/1.8/openssl/buffering.rb:35:in `sysread'' /usr/lib/ruby/1.8/openssl/buffering.rb:35:in `fill_rbuff'' /usr/lib/ruby/1.8/openssl/buffering.rb:106:in `gets'' /usr/lib/ruby/1.8/net/imap.rb:992:in `get_response'' /usr/lib/ruby/1.8/net/imap.rb:930:in `receive_responses'' /usr/lib/ruby/1.8/net/imap.rb:923:in `initialize'' /usr/lib/ruby/1.8/net/imap.rb:922:in `start'' /usr/lib/ruby/1.8/net/imap.rb:922:in `initialize'' /home/me/monolith/app/controllers/user_sessions_controller.rb:17:in `new'' /home/me/monolith/app/controllers/user_sessions_controller.rb:17:in `authenticate_user'' /home/me/monolith/app/controllers/user_sessions_controller.rb:32:in `create'' Thanks! -- Posted via http://www.ruby-forum.com/.
