NAME
Net::Packet::Desc - base class for all desc modules
DESCRIPTION
This is the base class for Net::Packet::DescL2, Net::Packet::DescL3 and Net::Packet::DescL4 modules.
It just provides those layers with inheritable attributes and methods.
A descriptor is required when you want to send frames over network.
ATTRIBUTES
- dev
-
Network device to use to send frames. Default to use dev set in default $Env object.
- ip
-
Same as above for IP. This is the source IP address to use.
- ip6
-
Same as above for IPv6. This is the source IPv6 address to use.
- mac
-
Same as above for MAC. This is the source MAC address to use.
- gatewayIp
-
Same as above, for gateway IP address.
- gatewayMac
-
Same as above, for gateway MAC address. It is not automatically set here. It is automatically set only under Windows, when using a Net::Packet::DescL3 object.
- target
-
Used to create a Net::Packet::DescL3 and Net::Packet::DescL4. At these layers, one MUST specifiy the target IP address to tell kernel where to send frames.
- targetMac
-
Used to automatically build layer 2 when using a Net::Packet::DescL3 object under Windows.
- protocol
-
This is the transport protocol to use (TCP, UDP, ...). Used in Net::Packet::DescL4 objects. Default to TCP.
- family
-
Same as abose, to tell which network protocol to use (IPv4, IPv6).
METHODS
- send (scalar)
-
Send the raw data passed as a parameter.
- close
-
Close the descriptor.
- isDescL2
- isDescL3
- isDescL4
-
Returns true if Desc is of specified type, false otherwise.
