- .SH NAME
- ettercap - A multipurpose sniffer over switched LANs
- .SH SYNOPSIS
- .B ettercap
- [fIOPTIONfR] [fIHOST:PORTfR] [fIHOST:PORTfR] [fIMACfR] [fIMACfR]
- .SH DESCRIPTION
- Self explaining ncurses interface available, with help windows

- .PP
- ettercap @VERSION@ (c) 2000 ALoR & NaGA
- .TP
- fB-NfR, fB--simplefR

- start in silent mode (no arp storm on start up)
- .br
- If you want to sniff in "passive" mode (like sniffit).
- .br
- For mac or arp based sniffing you have to know the ip and the mac of the two hosts.
- Theese can be achieved with "ettercap -Nl"
- .TP
- fB-bfR, fB--broadpingfR
- use a broadcast ping instead of arp storm on start up.
- .br
- this method is less intrusive, but even less accurate.
- some hosts will not respond upon this. (es. Windows)
- .br
- .TP
- fB-ufR, fB--udpfR
- sniff only UDP packets (default is TCP).
- .TP
- fB-pfR, fB--pluginfR NAME
- run the plugin "NAME".
- .br
- most plugins need a destination host. simply specify it after plugin name.
- .br
- Es:
- .br
- ettercap -Np ooze meltemi
- .br
- for the list of available plugins:
- .br
- ettercap -Np list
- .TP
- fB-afR, fB--arpsnifffR
- arp based sniffing (you must select two host for this)
- .br
- This is THE sniffer for switched LAN.
- .br
- man-in-the-middle technique is available only with this method.
- .br
- in silent mode : you must specify two IP and two MAC
- .br
- Es:
- .br
- ettercap -za IP IP MAC MAC
- .TP
- fB-sfR, fB--snifffR
- ip based sniffing
- .br
- you can select only source, only dest, with or without port, or nothing (to sniff all connections)
- .br
- Es:
- .br
- ettercap -Ns ghibli meltemi:1024
- .br
- ettercap -Ns ghibli:139
- .br
- ettercap -Ns
- .TP
- fB-mfR, fB--macsnifffR
- mac based sniffing (you must select two host for this)
- .br
- Very useful to sniff TCP trafic with remote hosts.
- .br
- Simply select the gateway and a victim host, and you will see all its connection to and from internet.
- .br
- in silent mode : you must specify two MAC
- .br
- Es:
- .br
- ettercap -zm MAC MAC
- .TP
- fB-lfR, fB--listfR
- lists all the hosts in the lan, reporting each MAC address.
- .TP
- fB-CfR, fB--collectfR
- collect all users and password from any connection.

- Es:
- .br
- ettercap -NCzs
- .br

- .TP
- fB-ifR, fB--ifacefR IFACE
- network interface to be used
- .TP
- fB-nfR, fB--netmaskfR NETMASK
- the netmask used to scan the lan. (in dotted notation)
- .br
- the default is your current ifconfig netmask
- .TP
- fB-cfR, fB--checkfR
- check if you were poisoned by other poisoners in the LAN
- .TP
- fB-tfR, fB--linktypefR
- check if you are on a switched lan or not...
- .TP
- fB-vfR, fB--versionfR
- print version
- .TP
