Object
An implementation of an HTTP proxy. To use it, instantiate it, then pass the instantiated object via the :proxy key to Net::SSH.start:
require 'net/ssh/proxy/http' proxy = Net::SSH::Proxy::HTTP.new('proxy.host', proxy_port) Net::SSH.start('host', 'user', :proxy => proxy) do |ssh| ... end
If the proxy requires authentication, you can pass :user and :password to the proxy’s constructor:
proxy = Net::SSH::Proxy::HTTP.new('proxy.host', proxy_port, :user => "user", :password => "password")
Note that HTTP digest authentication is not supported; Basic only at this point.
Create a new socket factory that tunnels via the given host and port. The options parameter is a hash of additional settings that can be used to tweak this proxy connection. Specifically, the following options are supported:
:user => the user name to use when authenticating to the proxy
:password => the password to use when authenticating
# File lib/net/ssh/proxy/http.rb, line 43 43: def initialize(proxy_host, proxy_port=80, options={}) 44: @proxy_host = proxy_host 45: @proxy_port = proxy_port 46: @options = options 47: end
Return a new socket connected to the given host and port via the proxy that was requested when the socket factory was instantiated.
