The Flow type contains all the information of a connection dumped from the conntrack table. Note that the Flow type can be used to support multiple extended formats as well to allow for expansions on the library. Thus, all fields will be optional to support the various formats/options/configs that can be set by the linux kernel.

Fields

id: Option<u32>

Unique id assigned to this conntrack entry.

origin: Option<IpTuple>

The origin of the network traffic, containing the src address and sport, the dst address and dport, and protocol information.

reply: Option<IpTuple>

The reply of the network traffic, containing the src address and sport, the dst address and dport, and protocol information.

proto_info: Option<ProtoInfo>

Metadata specific to the protocol being used to facilitate the network transfer.

counter_origin: Option<Counter>

Byte and packet counter data relative to the traffic origin. Enable with sysctl -w net.netfilter.nf_conntrack_acct=1

counter_reply: Option<Counter>

Byte and packet counter data relative to the traffic reply. Enable with sysctl -w net.netfilter.nf_conntrack_acct=1

timeout: Option<Duration>

Duration until conntrack entry is invalidated; reset to initial value when connection sees a new packet. Default TCP connection timeout is 5 days.

status: Option<Vec<String>>

Contains the status values parsed into the various status flags, represented as strings.

entry_use: Option<u32>

Use is a reference count for the connection used internally for garbage collection.

zone: Option<u16>

mark: Option<u32>

mark_mask: Option<u32>

timestamp: Option<Timestamp>

status_mask: Option<u32>

helper: Option<Helper>

nat_src: Option<Nat>

seq_adj_orig: Option<SeqAdj>

seq_adj_repl: Option<SeqAdj>

sec_ctx: Option<SecCtx>

sec_mark: Option<u32>

exp: Option<Exp>
