2023年1月23日 374次阅读 来源: 骑着炮弹进城

基本命令

ls()
List all available protocols and protocol options
lsc()
List all available scapy command functions
conf
Show/set scapy configuration parameters

生成数据包

# Setting protocol fields
>>> ip=IP(src="10.0.0.1")
>>> ip.dst="10.0.0.2"
# Combining layers
>>> l3=IP()/TCP()
>>> l2=Ether()/l3
# Splitting layers apart
>>> l2.getlayer(1)
<IP frag=0 proto=tcp |<TCP |>>
>>> l2.getlayer(2)
<TCP |>

显示数据包

# Show an entire packet
>>> (Ether()/IPv6()).show()
###[ Ethernet ]###
dst= ff:ff:ff:ff:ff:ff
src= 00:00:00:00:00:00
type= 0x86dd
###[ IPv6 ]###
version= 6
tc= 0
fl= 0
plen= None
nh= No Next Header
hlim= 64
src= ::1
dst= ::1
# Show field types with default values
>>> ls(UDP())
sport : ShortEnumField = 1025 (53)
dport : ShortEnumField = 53 (53)
len : ShortField = None (None)
chksum : XShortField = None (None)

指定地址和值（Specifying Addresses and Values）

指定IP值 Explicit IP address (use quotation marks)

>>> IP(dst="192.0.2.1")

指定域名 DNS name to be resolved at time of transmission

>>> IP(dst="example.com")
# IP network (results in a packet template)
>>> IP(dst="192.0.2.0/24")

随机生成ip和mac Random addresses with RandIP() and RandMAC()


>>> IP(dst=RandIP())
>>> Ether(dst=RandMAC())

指定TTL范围 Set a range of numbers to be used (template)

>>> IP(ttl=(1,30))
# Random numbers with RandInt() and RandLong()
>>> IP(id=RandInt())

发送包（Sending Packets）

send(pkt, inter=0, loop=0, count=1, iface=N)
发送三层包（Send one or more packets at layer three）
sendp(pkt, inter=0, loop=0, count=1, iface=N)
发送二层包（Send one or more packets at layer two）
sendpfast(pkt, pps=N, mbps=N, loop=0, iface=N)
Send packets much faster at layer two using tcpreplay

>>> send(IP(dst="192.0.2.1")/UDP(dport=53))
.
Sent 1 packets.
>>> sendp(Ether()/IP(dst="192.0.2.1")/UDP(dport=53))
.
Sent 1 packets.

发送和接受包（Sending and Receiving Packets）

sr(pkt, filter=N, iface=N), srp(…)
Send packets and receive replies
sr1(pkt, inter=0, loop=0, count=1, iface=N), srp1(…)
Send packets and return only the first reply
srloop(pkt, timeout=N, count=N), srploop(…)
Send packets in a loop and print each reply

>>> srloop(IP(dst="packetlife.net")/ICMP(), count=3)
RECV 1: IP / ICMP 174.143.213.184 > 192.168.1.140 RECV 1: IP / ICMP 174.143.213.184 > 192.168.1.140 RECV 1: IP / ICMP 174.143.213.184 > 192.168.1.140

嗅探包（Sniffing Packets）

sniff(count=0, store=1, timeout=N)
Record packets off the wire; returns a list of packets when stopped

# Capture up to 100 packets (or stop with ctrl-c)
>>> pkts=sniff(count=100, iface="eth0")
>>> pkts
<Sniffed: TCP:92 UDP:7 ICMP:1 Other:0>
