Struct nflog::Message
[−]
[src]
pub struct Message { /* fields omitted */ }Opaque struct Message: abstracts NFLOG data representing a packet data and metadata
Methods
impl Message[src]
fn get_msg_packet_hdr(&self) -> NfMsgPacketHdr
Return the metaheader that wraps the packet
fn get_hwtype(&self) -> u16
Get the hardware link layer type from logging data
fn get_packet_hwhdr<'a>(&'a self) -> &'a [u8]
Get the hardware link layer header
fn get_nfmark(&self) -> u32
Get the packet mark
fn get_timestamp(&self) -> Result<timeval, NflogError>
Get the packet timestamp
fn get_indev(&self) -> u32
Get the interface that the packet was received through
Returns the index of the device the packet was received via.
If the returned index is 0, the packet was locally generated or the
input interface is not known (ie. POSTROUTING?).
fn get_physindev(&self) -> u32
Get the physical interface that the packet was received through
Returns the index of the physical device the packet was received via.
If the returned index is 0, the packet was locally generated or the
physical input interface is no longer known (ie. POSTROUTING?).
fn get_outdev(&self) -> u32
Get the interface that the packet will be routed out
Returns the index of the device the packet will be sent out.
If the returned index is 0, the packet is destined to localhost or
the output interface is not yet known (ie. PREROUTING?).
fn get_physoutdev(&self) -> u32
Get the physical interface that the packet will be routed out
Returns the index of the physical device the packet will be sent out.
If the returned index is 0, the packet is destined to localhost or
the physical output interface is not yet known (ie. PREROUTING?).
fn get_packet_hw<'a>(&'a self) -> Result<HwAddr<'a>, NflogError>
Get hardware address
Retrieves the hardware address associated with the given packet.
For ethernet packets, the hardware address returned (if any) will be the MAC address of the packet source host.
The destination MAC address is not known until after POSTROUTING and a successful ARP request, so cannot currently be retrieved.
fn get_payload<'a>(&'a self) -> &'a [u8]
Get payload
Depending on set_mode, we may not have a payload
The actual amount and type of data retrieved by this function will
depend on the mode set with the set_mode() function.
fn get_prefix(&self) -> Result<String, Utf8Error>
Return the log prefix as configured using --nflog-prefix "..."
in iptables rules.
fn get_uid(&self) -> Result<u32, &str>
Available only for outgoing packets
fn get_gid(&self) -> Result<u32, NflogError>
Available only for outgoing packets
fn get_seq(&self) -> Result<u32, NflogError>
Get the local nflog sequence number
You must enable this via set_flags(nflog::CfgFlags::CfgFlagsSeq).
fn get_seq_global(&self) -> Result<u32, NflogError>
Get the global nflog sequence number
You must enable this via set_flags(nflog::CfgFlags::CfgFlagsSeqGlobal).
fn as_xml_str(&self, flags: &[XMLFormatFlags]) -> Result<String, Utf8Error>
Print the logged packet in XML format into a buffer
