I am trying to parse an rss feed with Ruby. This is my (working) code, with the actual feed url:
include 'rss'
myfeed = RSS::Parser.parse('http://allmusicnews.altervista.org/blog/feed/', false)
If I run it from my development computer (Mac OS 10.9), all works fine. If I run it from my server (Debian 7), all i get is:
/home/daniele/.rvm/rubies/ruby-2.2.0/lib/ruby/2.2.0/net/http.rb:879:in `initialize': Connection refused - connect(2) for "allmusicnews.altervista.org" port 80 (Errno::ECONNREFUSED)

This does not happen with other rss feeds. example: feeds.blogo.it/soundsblog/it seems working well on both platforms.
I am using the same Ruby version (2.2.0), installed with RVM on both the computers. Same gems too.
Any clue, at least about what to look for?
ps: it may seem something related to connection timeout, but as I run my script suddenly I see the error message above, there's no idle waiting time...
Please ignore my question. I was shooting to the wrong target.
Actually I'm afraid to have some blacklistish problem with my production machine. I cannot connect to altervista.org server in any way (lynx, telnet), I keep getting "connection refused error", so there's nothing to do with my Ruby code...

I tried to make the same request and got the same error.
after changing the URL from http://api.github.com into https://api.github.com it working.
I am trying to make HTTP requests via Ruby. When running the following code:
require "net/http"
require "uri"
uri = URI.parse("http://google.com/")
# Will print response.body
Net::HTTP.get_print(uri)
I get the following error:

This is probably proxy related, but I am not sure. How can I fix this problem?
Ruby will automatically use the HTTP proxy as specified in your environment variables.
EXPORT http_proxy=http://foo.bar:8080/
ruby your_http_script.rb
Same thing happened to me. No proxy was in use.
The reason was that I was not running as root and /etc/resolv.conf didn't have read permissions to anyone other than root. Adding read permissions solved the host resolving problem.
I have a couple of dedicated servers where I have background workers running for days sometimes before restart. When this happens (that they run for more than 24 hours it seems) then I start to get errors like this:
getaddrinfo: Temporary failure in name resolution

The error will occur for ALL remote calls from that specific process, until it has been restarted (NOT hardware/server restart, just the ruby process). I have double-checked/confirmed that restarting the process works as a fix, since I have tried to SSH into the server, and run a new process along side the failing one, and this one would work flawlessly, while the faulty one still failed.
So my question is, why is this happening, and how can I resolve the issue in an other way than restarting the process every day?
I am on ruby 1.9.3 p194 and the background jobs are processed with the sidekiq gem (however I don't suspect that one to be responsible for the mess).
The servers are situated at http://www.hetzner.de (however I don't think they are to blame, since it's happening in-process)
UPDATE
Along side the above smtp call errors, I'm also getting errors like this, when doing simple http requests. This also resolves after a process restart:
# (Errno::EHOSTUNREACH) "No route to host - connect(2)"

Currently run 150 plus scenarios nightly approximately 5000 steps. I see the following error occur around 10 times in the 5000 steps. Not a lot, nor on the same step, however don't know what to do to fix. Currently wrapping in a rescue block and retrying to work around error.
Any suggestions would be great.
Thanks,
Jim

Looks like you are running out of ephemeral ports. You might want to change settings in the registry to use more ports. Refer below

I'm trying to connect to a service, I just generated this soap client from wsdl2ruby. Everything went fine. So I have no idea why this error is happening. This is a fresh install of ruby 1.8.7 on Windows, but I tested this on another Windows machine with Ruby 1.8.6 and on a Debian server with REE 1.8.7 - same error. My gut feeling is that it has to do with the httpclient lib - but I can't find anything on google - regarding this err, other than some references to Pythong and tcl - which seem to be unrelated. Also I'm trying to connect to wsdl service that is on httpS - but I didn't have this problem before and there were no changes on the server.
Does anyone have any insight?
OK nevermind people. For anyone else looking into this cryptic message if you are using wsdl2ruby - make sure that you define your endpoint_url in the WhateverServiceClient.rb file generated by the wsdl3ruby.
