pycapng
Python library for reading, writing, and capturing network traffic in the pcapng file format.
pip install pycapng
- Read pcapng files packet by packet
- Write pcapng files with hand-crafted Ethernet/IP/TCP/UDP/ICMP/DNS/DHCP/NTP/TLS packets
- Capture live traffic with a Wireshark-style display filter (Linux / macOS)
- Reassemble fragmented IP packets
- Script packet flows with the built-in pcapsh engine
Reading a pcapng file
import pycapng
p = pycapng.PcapNG()
p.OpenFile("capture.pcapng", "r")
def on_packet(data: bytes, ts: int) -> None:
print(f"packet {len(data)} bytes ts={ts}")
p.ForeachPacket(on_packet)
p.CloseFile()
Writing packets
Raw bytes
import pycapng
p = pycapng.PcapNG()
p.OpenFile("out.pcapng", "w")
raw = bytes([0x45, 0x00, 0x00, 0x28]) # any bytes
p.WritePacket(raw)
p.CloseFile()
TCP
p.WriteTcpPacket(
src_ip="192.168.1.10", dst_ip="93.184.216.34",
src_port=54321, dst_port=80,
payload=b"GET / HTTP/1.1\r\nHost: example.com\r\n\r\n",
flags=0x02, # SYN
)
Build a packet without writing it
syn = p.BuildTcpPacket(
src_ip="10.0.0.1", dst_ip="10.0.0.2",
src_port=1234, dst_port=443,
payload=b"", flags=0x02,
)
# syn is bytes — inspect it, modify it, write it later
p.WritePacket(syn)
UDP / ICMP
pkt = p.BuildUdpPacket(
src_ip="10.0.0.1", dst_ip="8.8.8.8",
src_port=12345, dst_port=53,
payload=b"\x00\x01...", # your DNS query bytes
)
icmp = p.BuildIcmpPacket(
src_ip="10.0.0.1", dst_ip="10.0.0.2",
icmp_type=8, icmp_code=0, # Echo Request
payload=b"hello",
)
Application-layer helpers
# DNS
query = p.BuildDnsQuery("example.com")
response = p.BuildDNSResponse("example.com", "93.184.216.34")
# DHCP
discover = p.BuildDhcpDiscover()
offer = p.BuildDhcpOffer(client_mac="aa:bb:cc:dd:ee:ff",
offered_ip="192.168.1.100")
# NTP
req = p.BuildNtpRequest()
resp = p.BuildNtpReply()
# TLS handshake (produces realistic-looking bytes for testing)
ch = p.BuildTlsClientHello()
sh = p.BuildTlsServerHello()
ct = p.BuildTlsCertificate()
fin = p.BuildTlsFinished()
app = p.BuildTlsApplicationData(b"GET / HTTP/1.1\r\n")
Write with a timestamp
import time
p.WritePacketTime(raw_bytes, int(time.time() * 1e9)) # nanoseconds
Live capture
Requires root or CAP_NET_RAW on Linux, root or the network entitlement
on macOS.
Simple callback loop
import pycapng
with pycapng.Capture("eth0") as cap:
cap.set_filter("tcp.dstport == 443")
cap.loop(0, lambda pkt: print(f"{pkt.captured_len} bytes"))
Full example
import pycapng, signal
cap = pycapng.Capture(pycapng.capture_default_device())
cap.set_snaplen(65535)
cap.set_promisc(True)
cap.set_timeout(100) # ms between ring deliveries
cap.set_filter("ip and not arp")
signal.signal(signal.SIGINT, lambda *_: cap.break_loop())
def on_packet(pkt: pycapng.PacketInfo) -> None:
ts = pkt.timestamp_ns // 1_000_000_000
print(f"[{ts}] {pkt.direction} {pkt.captured_len}/{pkt.original_len} bytes")
cap.loop(0, on_packet)
stats = cap.get_stats()
print(f"received={stats.received} dropped={stats.dropped}")
cap.close()
Display filter syntax
The filter language is a subset of Wireshark's display filter syntax.
| Example | Meaning |
|---|---|
tcp |
any TCP packet |
tcp.dstport == 443 |
TCP to port 443 |
ip.src == 192.168.0.0/16 |
source in subnet |
tcp.flags.syn and not tcp.flags.ack |
SYN-only |
udp.port == 53 |
DNS (src or dst) |
ip.addr == 10.0.0.1 |
any direction to/from IP |
tcp and not (tcp.dstport == 80 or tcp.dstport == 443) |
non-web TCP |
eth.addr == aa:bb:cc:dd:ee:ff |
by MAC (src or dst) |
Built-in fields: eth.{src,dst,type,addr} · ip.{src,dst,proto,ttl,len,addr} ·
ip6.{src,dst} · tcp.{srcport,dstport,flags,flags.syn/ack/rst/fin,port} ·
udp.{srcport,dstport,port} · icmp.{type,code}
Capture directly to a pcapng file
# one-liner: capture 500 TLS packets and save to a file
pycapng.capture_to_file("eth0", "tls.pcapng",
filter="tcp.dstport == 443", count=500)
List available interfaces
for dev in pycapng.capture_list_devices():
print(dev["name"], "(loopback)" if dev["loopback"] else "")
iface = pycapng.capture_default_device()
IP fragment reassembly
import pycapng
r = pycapng.Reassembler()
p = pycapng.PcapNG()
p.OpenFile("fragments.pcapng", "r")
def on_packet(data: bytes, ts: int) -> None:
complete = r.add(data)
if complete:
print(f"reassembled datagram: {len(complete)} bytes")
p.ForeachPacket(on_packet)
pcapsh script engine
The pycapng.pcapsh submodule exposes a scripting engine for building and
replaying packet flows declaratively.
from pycapng import pcapsh
engine = pcapsh.PcapSH()
engine.RunScript("my_flow.pcapsh", "out.pcapng")
TLS record builders are also available as standalone functions:
from pycapng.pcapsh import (
tls_client_hello, tls_server_hello,
tls_certificate, tls_finished,
tls_application_data,
)
C library
pycapng is the Python interface to libpcapng,
a C library that also ships a standalone command-line tool (pcapsh) and a
full C API. See the repository for C usage, build instructions, and the
capture API reference.

Transparency logA note on package security
PyPI is a repository for distributing packages, not a service for auditing them. While third-party security researchers and our staff do their best to detect and remove malicious packages, PyPI cannot guarantee the quality, security or suitability of any given package.
