What’s included in the cheat sheet?

The following categories and items have been included in the cheat sheet:

Wireshark Capturing Modes

Wireshark Capturing Modes
Promiscuous mode		Sets interface to capture all packets on a network segment to which it is associated to
Monitor mode		setup the Wireless interface to capture all traffic it can receive (Unix/Linux only)

Filter Types

Filter Types
Capture filter			Filter packets during capture
Display Filter			Hide Packets from a capture display

Capture Filter Syntax

Capture filter Syntax
Syntax			protocol		direction	hosts		value		Logical operator				Expressions
Example			tcp		src	192.168.1.1		80		and				tcp dst 202.164.30.1

Display Filter Syntax

Display Filter Syntax
Syntax			protocol	String 1			String 2	Comparison Operator		value			logical operator		Expressions
Example			http	dest			ip	==		192.168.1.1			and		tcp port

Protocols – Values

Protocols - Values
ether, fddi, ip, arp, rarp, decnet, lat, sca, moprc, mopdl, tcp and udp

Filtering packets (Display Filters)

Filtering packets (Display Filters)
Operator	Description	Example
eq or ==	Equal	ip.dest == 192.168.1.1
ne or !=	Not Equal	ip.dest != 192.168.1.1
gt or >	Greater than	frame.len > 10
lt or <	Less than	frame.len <10
ge or >=	Greater than or Equal	frame.len >= 10
le or <=	Less than or Equal	frame.len<=10

Miscellaneous Items

Miscellaneous
Slice Operator			[…] - Range of values
Membership Operator			{} - In
CTRL+E -			Start/Stop Capturing

Logical Operators

Logical Operators
Operator	Description	Example
and or &&	Logical AND	All the conditions should match
or or \|\|	Logical OR	Either all or one of the condition should match
xor or ^^	Logical XOR	exclusive alternation – Only one of the two conditions should match not both
not or !	NOT(Negation)	Not equal to
[n] […]	Substring operator	Filter a specific word or text

Default columns in a packet capture output

Default columns in a packet capture output
No.			Frame number from the beginning of the packet capture
Time			Seconds from the first frame
Source (src)			Source address, commonly an IPv4, IPv6 or Ethernet address
Destination (dst)			Destination address
Protocol			Protocol used in the Ethernet frame, IP packet, or TCP segment
Length			Length of the frame in bytes

Keyboard Shortcuts

Keyboard Shortcuts – main display window
Accelerator	Description	Accelerator	Description
Tab or Shift+Tab	Move between screen elements, e.g. from the toolbars to the packet list to the packet detail.	Alt+→ or Option+→	Move to the next packet in the selection history.
↓	Move to the next packet or detail item.	→	In the packet detail, opens the selected tree item.
↑	Move to the previous packet or detail item.	Shift+→	In the packet detail, opens the selected tree item and all of its subtrees.
Ctrl+ ↓ or F8	Move to the next packet, even if the packet list isn’t focused.	Ctrl+→	In the packet detail, opens all tree items.
Ctrl+ ↑ or F7	Move to the previous packet, even if the packet list isn’t focused.	Ctrl+←	In the packet detail, closes all tree items.
Ctrl+.	Move to the next packet of the conversation (TCP, UDP or IP).	Backspace	In the packet detail, jumps to the parent node.
Ctrl+,	Move to the previous packet of the conversation (TCP, UDP or IP).	Return or Enter	In the packet detail, toggles the selected tree item.
