如何正确使用 tor-privoxy Ruby gem？

Question

我正在使用 tor-privoxy Ruby gem。根据这个页面：https://github.com/pirj/tor-privoxy 我在 Arch Linux 安装中安装了“tor”和“privoxy”包。我发出命令：

sudo systemctl start privoxy.service
sudo systemctl start tor.service

服务状态，通过“systemctl status privoxy.service”和“systemctl status tor.service”：

我的 Ruby 脚本如下所示：

require 'mechanize'
require 'tor-privoxy'
require 'net/telnet'

def tor
  privoxy_agent ||= TorPrivoxy::Agent.new '127.0.0.1', '', {8118 => 9050} do |agent|
  sleep 20
   puts "New IP is #{agent.ip}"
  end
  return privoxy_agent
end

def switch_endpoint
  localhost = Net::Telnet::new("Host" => "localhost", "Port" => "9050", "Timeout" => 10, "Prompt" => /250 OK\n/)
  localhost.cmd('AUTHENTICATE ""') { |c| print c; throw "Cannot authenticate to Tor" if c != "250 OK\n" }
  localhost.cmd('signal NEWNYM') { |c| print c; throw "Cannot switch Tor to new route" if c != "250 OK\n" }
  localhost.close
end    

agent=tor

这表明我的 IP 地址仍然是原来的。当我尝试调用“switch_endpoint”方法时，出现错误：“ArgumentError: uncaught throw “Cannot authenticate to Tor”

但是，当我在 bash 提示符下发出此命令时：

torify wget -qO- https://check.torproject.org/ | grep -i congratulations

我没有收到任何错误，这表明我能够连接到 Tor 网络。

如何使 Tor-Privoxy 与 Ruby 和 Mechanize 一起工作？

Answer 1

我遇到了同样的问题，您可以在日志中看到您的身份验证命令被 tor 拒绝：

Socks 版本 65 无法识别。 （Tor 不是 http 代理。）

我设法使用Socksify 而不是 tor-privoxy 向 Tor 发送 telnet 命令。如果你使用 socksify，你就不再需要 privoxy。

这是一个动态切换 Tor 电路的工作示例：

首先启动 Tor 指定密码、控制端口和 socks 端口：

tor --CookieAuthentication 0 --HashedControlPassword "" --ControlPort 9050 --SocksPort 50001

然后你可以在 ruby​​ 中试试这个：

require 'net/telnet'
require 'socksify'
require 'mechanize'

original_ip = Mechanize.new.get("http://bot.whatismyipaddress.com").content
puts "original IP is : #{original_ip}"

# socksify will forward traffic to Tor so you dont need to set a proxy for Mechanize from there
TCPSocket::socks_server = "127.0.0.1"
TCPSocket::socks_port = "50001"
tor_port = 9050

2.times do
  #Switch IP
  localhost = Net::Telnet::new("Host" => "localhost", "Port" => "#{tor_port}", "Timeout" => 10, "Prompt" => /250 OK\n/)
  localhost.cmd('AUTHENTICATE ""') { |c| print c; throw "Cannot authenticate to Tor" if c != "250 OK\n" }
  localhost.cmd('signal NEWNYM') { |c| print c; throw "Cannot switch Tor to new route" if c != "250 OK\n" }
  localhost.close      
  sleep 5

  new_ip = Mechanize.new.get("http://bot.whatismyipaddress.com").content
  puts "new IP is #{new_ip}"
end
