class PacketFu::Config

The Config class holds various bits of useful default information for packet creation. If initialized without arguments, @iface will be set to ENV or Pcap.lookupdev (or lo), and the @pcapfile will be set to “/tmp/out.pcap” # (yes, it’s Linux-biased, sorry, fixing this is a TODO.)

Any number of instance variables can be passed in to the intialize function (as a hash), though only the expected network-related variables will be readable and writeable directly.

Examples

PacketFu::Config.new(:ip_saddr => "1.2.3.4").ip_saddr #=> "1.2.3.4"
PacketFu::Config.new(:foo=>"bar").foo #=> NomethodError: undefined method `foo'...

The config() function, however, does provide access to custom variables:

PacketFu::Config.new(:foo=>"bar").config[:foo] #=> "bar"
obj = PacketFu::Config.new(:foo=>"bar")
obj.config(:baz => "bat")
obj.config #=> {:iface=>"eth0", :baz=>"bat", :pcapfile=>"/tmp/out.pcap", :foo=>"bar"}
