Using the
PCAP_OPEN_OFFLINE
function: This method allows you to capture traffic from a file. You can specify the file path of the capture file as an argument to this function.
How do I filter and manipulate network traffic based on IP addresses using pcapp?
To filter and manipulate network traffic based on IP addresses using pcapp, you can use the PCAP_FILTER
function. You can pass a filter expression as an argument to this function. Here are some examples of filter expressions that you can use:
- To capture traffic from a specific IP address, you can use the following filter expression:
"ip src 192.168.1.1"
- To capture traffic to a specific IP address, you can use the following filter expression:
"ip dst 192.168.1.1"
You can also use pcapp to manipulate network traffic based on IP addresses. For example, you can use the PCAP_SET_SNAPLEN
function to set the capture length for each packet by IP addresses.
