ETTERCAP-CURSES(8) ETTERCAP-CURSES(8)
NAME
ettercap - Man page for the Ncurses GUI.
GENERAL DESCRIPTION
The curses GUI is quite simple and intuitive.
It is menu-driven. Every flag or function can be modified/called
through the upper menu. All user messages are printed in the bottom
window. If you want to see the old messages, you can scroll the window
buffer by pressing the UP, DOWN, PPAGE, NPAGE keys. The middle part is
used to display information or dialogs for the user.
The menus can be opened by pressing the relative hotkey. For the menus
the hotkey is represented by the uppercase initial letter of the title
(e.g. 'S' for Sniffing, 'T' for Targets). The functions within a menu
can be called by pressing the hotkey depicted near the function name on
the right. Hotkeys prefixed with 'C-' are to be used in conjunction
with the CTRL key (e.g. 'C-f' means CTRL+f).
You can switch the focus between the objects on the screen by pressing
the TAB key or by clicking on it with the mouse (if you are running
ettercap within an xterm). Mouse events are supported only through the
xterm. You can use the mouse to select objects, open a menu, choose a
function, scroll the elevators for the scrolling windows, etc etc.
When you open multiple windows in the middle part, they will overlap.
Use the TAB key to switch between them. Use CTRL+Q to close the focused
window.
You can also use CTRL+Q to close the input dialog if you want to cancel
the requested input. (i.e. you have selected the wrong function and you
want to go back).
To have a quick help on the shortcuts you can use against a particular
window press the SPACE key. A help window will be displayed with a list
of shortcuts that can be used. If the window does not appear, no short-
cuts are available.
HOW TO SELECT IT
To use the ncurses GUI you have to:
- compile ettercap with ncurses support (obviously)
- run it with the -C flag
Passing the -C flag is sufficient, but if you want you can pass other
flags that will be automatically set for the ncurses GUI. You will be
able to override them using the menu to change the options.
ONCE STARTED
As soon as ettercap is launched with the Ncurses GUI, you will be
prompted with multiple choices. The first screen lets you select if you
want to open a pcap file or dump the sniffed traffic to a file, if you
want unified sniffing or bridged one, permits you to set a pcap file on
the captured traffic and enables you to log all the sniffed data.
Once you have selected a sniffing method (from file, unified or
bridged) this screen will not be reachable anymore. The only way is to
restart ettercap.
Let's analyze each menu in the start screen:
File
Open...
Open a pcap file and analyze it. All the functionalities
available for live sniffing are in place except for those
sending or forwarding packets (mitm attacks and so
on...).
Dump to file...
All the traffic sniffed by the live capture will be
dumped to that file. The filters, not the targets, have
effects on this file, as all the packets received by pcap
will be dumped. The only way to not dump a certain packet
is to set a proper pcap filter (see below).
Exit
Exits from ettercap and returns to the command prompt.
Sniff
Unified sniffing...
Choosing this function you will be prompted to select the
network interface to be used for sniffing. The first up
and running interface is suggested in the input box. For
an explanation of what unified sniffing is, refer to
ettercap(8).
TIP: if you use the 'u' hotkey, this step will be skipped
and the default interface is automatically selected.
Bridged sniffing...
After selecting the two interfaces to be used, you will
enter the Bridged sniffing mode. For an explanation of
what bridged sniffing is, refer to ettercap(8).
Set pcap filter...
Here you can insert a tcpdump-like filter for the captur-
ing process.
IMPORTANT: if you manage to use a mitm attack, remember
that if ettercap does not see a packet, it will NOT be
forwarded. So be sure of what you are doing by setting a
pcap filter.
Options
Unoffensive
This enable/disable the unoffensive flag. The asterisk
'*' means "the option is enabled". Otherwise the option
is not enabled.
Promisc mode
Enable/disable the promisc mode for the live capture on a
network interface. This is an "asterisk-option" as the
unoffensive one.
Set netmask
Use the specified netmask instead of the one associated
with the current iface. This option is useful if you have
the NIC with an associated netmask of class B and you
want to scan (with the arp scan) only a C class.
THE INTERESTING PART
Once you have selected an offline sniffing or a live capture, the upper
menu is modified and you can start to do the interesting things...
Some of the following menu are only available in live capture.
Start
Start sniffing
Starts the sniffing process depending on what you have
selected on startup (live or from file)
Stop sniffing
Stops the sniffing thread.
Exit
Returns to your favourite shell ;)
Targets
Current Targets
Displays a list of hosts in each TARGET. You can selec-
tively remove a host by selecting it and press 'd' or add
a new host pressing 'a'. To switch between the two lists,
use the ARROWS keys.
Select TARGET(s)
Lets you select the TARGET(s) as explained in etter-
cap(8). The syntax is the same as for the command line
specification.
Protocol...
You can choose to sniff only TCP, only UDP or both (ALL).
Reverse matching
Reverse the matching of a packet. It is equivalent to a
NOT before the target specification.
Wipe Targets
Restores both TARGETS to ANY/ANY/ANY
Hosts
Hosts list
Displays the list of hosts detected through an ARP scan
or converted from the passive profiles. This list is used
by MITM attacks when the ANY target is selected, so if
you want to exclude a host from the attack, simply delete
it from the list.
You can remove a host from the list by pressing 'd', add
it to TARGET1 by pressing '1' or add it to TARGET2 by
pressing '2'.
Scan for hosts
Perform the ARP scan of the netmask if no TARGETS are
selected. If TARGETS was specified it only scans for
those hosts.
Load from file...
Loads the hosts list from a file previously saved with
"save to file" or hand crafted.
Save to file...
Save the current hosts list to a file.
View
Connections
Displays the connection list. To see detailed information
about a connection press 'd', or press 'k' to kill it. To
see the traffic for a specific connection, select it and
press enter. Once the two-panel interface is displayed
you can move the focus with the arrow keys. Press 'j' to
switch between joined and split visualization. Press 'k'
to kill the connection. Press 'y' to inject interactively
and 'Y' to inject a file. Note that it is important which
panel has the focus as the injected data will be sent to
that address.
HINT: connections marked with an asterisk contain
account(s) information.
Profiles
Displays the passive profile hosts list. Selecting a host
will display the relative details (including account with
user and pass for that host).
You can convert the passive profile list into the hosts
list by pressing 'c'. To purge remote hosts, press 'l'.
To purge local hosts, press 'r'. You can also dump the
current profile to a file by pressing 'd'; the dumped
file can be opened with etterlog(8).
HINT: profiles marked with an asterisk contain account(s)
information.
Statistics
Displays some statistics about the sniffing process.
Resolve IP addresses
Enables DNS resolution for all the sniffed IP address.
CAUTION: this will extremely slow down ettercap. By the
way the passive dns resolution is always active. It
sniffs dns replies and stores them in a cache. If an ip
address is present in that cache, it will be automati-
cally resolved. It is dns resolution for free... ;)
Visualization method
Change the visualization method for the sniffed data.
Available methods: ascii, hex, ebcdic, text, html.
Visualization regex
Set the visualization regular expression. Only packets
matching this regex will be displayed in the connection
data window.
Set the WiFi key
Set the WiFi key used to decrypt WiFi encrypted packets.
See ettercap(8) for the format of the key.
Mitm
[...] For each type of attack, a menu entry is displayed. Sim-
ply select the attack you want and fill the arguments
when asked. You can activate more than one attack at a
time.
Stop mitm attack(s)
Stops all the mitm attacks currently active.
Filters
Load a filter...
Load a precompiled filter file. The file must be compiled
with etterfilter(8) before it can be loaded.
Stop filtering
Unload the filter and stop filtering the connections.
Logging
Log all packets and infos...
Given a file name, it will create two files: filename.eci
(for information about hosts) and filename.ecp (for all
the interesting packets). This is the same as the -L
option.
Log only infos...
This is used only to sniff information about hosts (same
as the -l option).
Stop logging info
Come on... it is self explanatory.
Log user messages...
Will log all the messages appearing in the bottom window
(same as -m option).
Compressed file
Asterisk-option to control whether or not the logfile
should be compressed.
Plugins
Manage the plugins
Opens the plugin management window. You can select a
plugin and activate it by pressing 'enter'. Plugins
already active can be recognized by the [1] symbol
instead of [0]. If you select an active plugin, it will
be deactivated.
Load a plugin...
You can load a plugin file that is not in the default
search path. (remember that you can browse directories
with EC_UID permissions).
