1.安装依赖
yum install libpcap libpcap-devel
2.安装python依赖（python3.6以上版本）
$ pip3 install Cython
$ pip3 install python-libpcap
3.验证
from pylibpcap.pcap import rpcap
4.使用
# Multi-file quick merge
$ libpcap-merge -i test.pcap -o pcap.pcap port 502
$ libpcap-merge -i pcap/ -o pcap.pcap port 502
# Capture data packet
$ sudo libpcap-capture -i enp0s3 -v -p port 22
$ sudo libpcap-capture -i enp0s3 -o pcap.pcap port 22
# Write packet
$ libpcap-write --output pcap.pcap ac64175ffa41000ec6c9157e08004500004b8a1e400080060000c0a80002c0a80001c794006618e119b56ef0831d5018faf081910000030000231ee00000001d00c1020600c20f53494d415449432d524f4f542d4553c0010a
# Read packet
$ libpcap-read -i test.pcap -v -p port 502
Read pcap:
from pylibpcap.pcap import rpcap
for len, t, pkt in rpcap("tests/dns.pcap"):
print("Buf length:", len)
print("Time:", t)
print("Buf:", pkt)
Write pcap:
from pylibpcap import wpcap
buf = b'\x00\xc0\x9f2A\x8c\x00\xe0\x18\xb1\x0c\xad\x08\x00E\x00\x008' \
b'\x00\x00@\x00@\x11eG\xc0\xa8\xaa\x08\xc0\xa8\xaa\x14\x80\x1b' \
b'\x005\x00$\x85\xed\x102\x01\x00\x00\x01\x00\x00\x00\x00\x00' \
b'\x00\x06google\x03com\x00\x00\x10\x00\x01'
wpcap(buf, "pcap.pcap")
wpcap([buf, buf], "pcap.pcap)
from pylibpcap import OpenPcap
with OpenPcap("pcap.pcap", "a") as f:
f.write(buf)
Merge pcap:
from pylibpcap.pcap import mpcap
mpcap("demo.pcap", "demo2.pcap")
mpcap("pcap/", "output.pcap", "port 502")
Get first iface:
from pylibpcap.pcap import get_first_iface
print(get_first_iface())
Get iface list:
from pylibpcap import get_iface_list
print(get_iface_list())
Send raw packet:
from pylibpcap import send_packet
send_packet("enp2s0", b"")
Capture data:
from pylibpcap.pcap import sniff
for plen, t, buf in sniff("enp2s0", filters="port 53", count=-1, promisc=1, out_file="pcap.pcap"):
print("[+]: Payload len=", plen)
print("[+]: Time", t)
print("[+]: Payload", buf)
from pylibpcap.base import Sniff
sniffobj = Sniff("enp2s0", filters="port 53", count=-1, promisc=1, out_file="pcap.pcap")
for plen, t, buf in sniffobj.capture():
print("[+]: Payload len=", plen)
print("[+]: Time", t)
print("[+]: Payload", buf)
stats = sniffobj.stats()
print(stats.capture_cnt, " packets captured")
print(stats.ps_recv, " packets received by filter")
print(stats.ps_drop, " packets dropped by kernel")
print(stats.ps_ifdrop, " packets dropped by iface")
