Hello all, Two questions: 1. in the example below, is our corporate firewall the reason I for the error? 2. if so, how can I configure ruby to use the firewall specified in http\_proxy? Details: I’m trying to connect to an outside http resource but I suspect our corporate firewall is blocking the normal route: $ ruby -rbio -e ‘reg = Bio::Registry.new’ /usr/lib/ruby/1.8/net/http.rb:560:in `initialize': No route to host - connect(2) (Errno::EHOSTUNREACH) from /usr/lib/ruby/1.8/net/http.rb:560:in `open’ from /usr/lib/ruby/1.8/net/http.rb:560:in `connect' from /usr/lib/ruby/1.8/timeout.rb:48:in `timeout’ from /usr/lib/ruby/1.8/timeout.rb:76:in `timeout' from /usr/lib/ruby/1.8/net/http.rb:560:in `connect’ from /usr/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/lib/ruby/1.8/net/http.rb:542:in `start’ from /usr/lib/ruby/1.8/net/http.rb:440:in `start' from /usr/lib/ruby/1.8/bio/io/registry.rb:190:in `read\_remote’ from /usr/lib/ruby/1.8/bio/io/registry.rb:126:in `initialize' from -e:1:in `new’ from -e:1 $ ruby -v ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux] $ lsb\_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 7.10 Release: 7.10 Codename: gutsy The environment variable http\_proxy is configured: $ env | grep -c http\_proxy 1 and works for elinks: $ ( elinks -dump [google.com](http://google.com) | wc -l ) 45 In fact, if I unset http\_proxy, elinks doesn’t work: $ ( unset http\_proxy ; elinks -dump [google.com](http://google.com) | wc -l ) ELinks: No route to host 0 Any pointers in the right direction greatly appreciated. Suggestions for a more simple test also appreciated. Regards, - Robert ---

Specifically, this is the link I looked at: [http://ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html](http://ruby-doc.org/stdlib/libdoc/net/http/rdoc/classes/Net/HTTP.html) To demonstrate that I can get the proxy to work, I picked google as a simple example. Here’s what I can do with elinks and with the http\_proxy environment variable set: $ elinks -source [http://www.google.com](http://www.google.com) | wc 2 173 5212 With ruby this code works: $ ruby -r’net/http’ -e ’ proxy\_addr = “www-gw32” ; proxy\_port = 3128 ; res=Net::HTTP::Proxy(proxy\_addr, proxy\_port).start(“[www.google.com](http://www.google.com)”) {|http| http.get(“/”); } puts res.body ; ’ | wc 3 173 5213 While I understand that example (mostly), I don’t understand how to wrap that around my existing code. Outside of the proxy, this works just fine: ruby -rbio -e ‘reg = Bio::Registry.new’ When I’m behind the proxy, how can I tell Bio::Registry to use the proxy connection? Regards, - Robert ---

Can you give me a pointer to Bio::Registry? Ed On Dec 19, 2007 2:56 PM, Robert C.

You can install bioruby like so on Ubuntu Feisty and Gutsy: $ sudo apt-get install libbio-ruby ruby You can test if it works with this bit of code: $ ruby -rbio -le ‘seq = Bio::Sequence::NA.new(“atgcatgcaaaa”) ; print seq’ Is that what you were asking?

I was more interested in the API docs. What is the main site? Ed On Dec 27, 2007 9:57 PM, Robert C.
