Packet capturing - Filter options

The following is a list of filter options available for free-hand filtering when Packet capturing in WinGate.

Filter

Description

packet.payload.byte

byte (8 bits)

At an offset from the start of packet (start of ethernet header) (e.g. packet.payload.byte[2])

packet.payload.word

word (16 bits)

At an offset (e.g. packet.payload.word[2])

packet.payload.dword

(dword) (32 bits)

At an offset (e.g. packet.payload.word[2])

packet.payload.nword

packet.payload.ndword

ethernet.dst

ethernet destination MAC address

ethernet.src

ethernet source MAC

ethernet.type

ethernet packet type (e.g 0x8000 = IP packet, 0x0806 = ARP)

ethernet.payload.byte

byte (8 bits)

At an offset from start of ethernet payload (normally IP packet)

ethernet.payload.word

word (16 bits)

At an offset (e.g. ethernet.payload.word[2])

ethernet.payload.dword

(dword) (32 bits)

At an offset (e.g. ethernet.payload.dword[2])

ethernet.payload.nword

Used as an option to dword or word. When you wish to omit conversion to host byte ordering

ethernet.payload.ndword

arp.hwaddresstype

hardware address type in ARP packet

arp.protoaddresstype

protocol address type in ARP packet

arp.hwaddresssize

hardware address size in ARP packet

arp.protoaddresssize

protocol address size in ARP packet

arp.operation

arp operation (request or response)

arp.sendermac

arp sender MAC address (who is doing the lookup)

arp.senderip

arp sender IP address

arp.targetmac

MAC address you are looking up

arp.targetip

IP address you are looking up

ip.payload.byte

payload of IP packet

ip.payload.word

 

ip.payload.dword

 

ip.payload.nword

 

ip.payload.ndword

 

ip.version

 

ip.tos

 

ip.length

 

ip.id

 

ip.frag

Value of the Packet fragmentation indicator. If a packet is not fragmented, this value is 0 (zero) or 0x0040. (0x0040 means it should not be fragmented by intermediate routers).

ip.ttl

0 - 255 TTL value

ip.protocol

next level protocol (e.g. 6 = TCP, 1 = ICMP, 17 = UDP)

ip.checksum

checksum

ip.src

source IP address

ip.dst

dest IP address

udp.src

UDP source port

udp.dst

UDP dest port

udp.length

UDP packet length (including header?)

udp.checksum

UDP checksum

tcp.src

TCP source port

tcp.dst

TCP dest port

tcp.seq

TCP sequence number

tcp.ack

TCP ack number

tcp.length

TCP length (header or payload?)

tcp.flags

TCP flags

tcp.window

TCP receive window

tcp.checksum

TCP checksum

tcp.urgent

TCP urgent pointer

tcp.port

TCP source or dest port (matches on either).

Note

When using tcp.port or udp.port filters, you can simply use the word port (instead of tcp.port or udp.port).

udp.port

UDP source or dest port (matches on either)

ip.addr

IP source or dest address (matches on either)

ip.address

IP source or dest address (matches on either)

You can use basic Full-Text Searches against the page title and body to find matching articles. Use the following search modifiers to refine your query:

  • event management (no quotes) will find all pages containing the words "event" OR "management"
  • "event management" (with quotes) will find all pages containing the phrase "event management"
  • +event -management will find all pages containing the word "event", AND NOT the word "management"
