|
|
|
- Capture all TCP traffic showing contents (ASCII) in console:
|
|
|
|

|
|
|
|

|
|
|

`tcpdump host {{www.example.com}}`
|
|
|
|
- Capture the traffic from a specific interface, source, destination and destination port:
|
|
|

`tcpdump -i {{eth0}} src {{192.168.1.1}} and dst {{192.168.1.2}} and dst port 80`
|
|
