snort2pcap

Feed in snort events, get pcaps out

Usage

Call write_pcap with the following arguments:

required

• packets; see data structure below
• fpath; file path, must not already exist

optional

• snaplen=123; max length of captured packets, in octets (see libpcap file format)
• linktype=1; since dummy MACs have been hard coded, probably best to leave this alone

list = [packet_1, packet_2, ... packet_n]

packet_n = (snort_packet_descriptor, packet_data)

snort_packet_descriptor = {

"sensor_id": 123, # number

"event_id": 234, # number

"packet_second": 345, # number

"packet_microsecond": 456, # number

"linktype": 7, # number

"packet_length": 890, # number

"packet_data": "AAAAb==" # base64 string

}

packet_data = "AAAAb==" # base64 string

Result will be a file at fpath containing all the packets in the order they were provided.

If you have multiple events and want them in separate files, make a list for each event and call write_pcap() for each list.
