PacketTypeMatch

Example:

>>> from linuxnet.iptables import PacketTypeMatch
>>> m = PacketTypeMatch()
>>> m.packet_type().equals('broadcast')
<linuxnet.iptables.matches.packettypematch.PacketTypeMatch object at 0x7f1bee6ae240>
>>> m.to_iptables_args()
['-m', 'pkttype', '--pkt-type', 'broadcast']
>>> print(m.packet_type().get_value())
broadcast

class PacketTypeMatch

Match against the packet type

static get_match_name() → str

Returns the iptables(8) match extension name

get_criteria() → Iterable[Criterion]

Returns the packet type match criteria (only one).

packet_type() → PacketTypeCriterion

Compare with the packet type

---

PacketTypeCriterion

class PacketTypeCriterion(match: Match)

Compare with the packet type

The comparison value is a string.

any() → Match

Match any value.

This method is used when creating a Criterion in order to search an existing chain for rules that try to match against certain packet properties (e.g. input interface) without being particular about the specific property value (e.g. eth0).

compare(is_equal: bool, *args, **kwargs) → Match

Alternative method used for comparisons. It invokes equals() (or not_equals()) with args and kwargs if is_equal is True (or False).

equals(value) → Match

Compare with the specified value

get_iptables_option() → str

Returns the iptables(8) option

get_value() → Any

Returns the criterion value

is_positive() → bool

Returns the ‘polarity’ of the criterion: True for equals() or False for not_equals()

Raises IptablesError if the criterion is not set

is_set() → bool

Returns True if the criterion has been set

not_equals(*args, **kwargs) → Match

Express inequality comparison against the argument values.

The arguments of this method are the same as those of the equals() method.

This method invokes the equals() method and then reverses the polarity.

Returns this Match object.
