Question

我正在尝试用Ruby解析rss feed。这是我的（工作）代码，带有实际的feed url：

include 'rss'

myfeed = RSS::Parser.parse('http://allmusicnews.altervista.org/blog/feed/', false)

如果我从我的开发计算机（Mac OS 10.9）运行它，一切正常。如果我从我的服务器（Debian 7）运行它，我得到的只是：

/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)

其他rss Feed不会发生这种情况。例如：feeds.blogo.it/soundsblog/it似乎在两个平台上都运行良好。

我使用的是同一个Ruby版本（2.2.0），在两台计算机上都安装了RVM。同样的宝石。

任何线索，至少关于要寻找什么？

ps：它可能看起来与连接超时有关，但是当我突然运行我的脚本时，我看到上面的错误信息，没有空闲的等待时间......

Answer 1

请忽略我的问题。我射向了错误的目标。

实际上我害怕生产机器出现一些黑名单问题。我无法以任何方式连接到altervista.org服务器（lynx，telnet），我一直收到“连接拒绝错误”，所以这与我的Ruby代码无关......

ruby：来自http.rb的ECONNREFUSED
