# Simple Scapy Packet Capture
|
||||
Here is a Python script that uses the Scapy library to capture a packet:
|
||||
|
||||
```
|
||||
from scapy.all import *
|
||||
|
||||
# Define a callback function
|
||||
def packet_callback(packet):
|
||||
print(packet.show())
|
||||
|
||||
# Use the sniff() function to capture packets
|
||||
sniff(prn=packet_callback, filter="tcp", count=1)
|
||||
```
|
||||
|
||||
This script uses the `sniff()` function from Scapy to capture packets. The `prn` argument is set to a callback function, `packet_callback`, which is called for each packet captured. The filter argument is set to "tcp" to capture only TCP packets, and the count argument is set to 1 to stop capturing after the first packet is captured. The `show()` function is used to display the packet information.
|
||||
|
||||
You can also use `filter` to capture specific IP or port.
|
||||
|
||||
```
|
||||
sniff(prn=packet_callback, filter="tcp and host 10.1.1.2 and port 80", count=1)
|
||||
```
|
||||
It's important to note that capturing packets may require root/admin permissions.
