我正在尝试使用 dpkt 从 pcap 数据包中获取 ipv6 扩展标头并将其打印出来。但由于某种原因它没有工作。我尝试了很多不同的方法。这是导致问题的代码部分。有没有人知道如何解决这个问题?ps 缺少关于 dpkt for ipv6 的示例代码
# For each packet in the pcap process the contents
for ts, buf in pcap:
# Unpack the Ethernet frame (mac src/dst, ethertype)
eth = dpkt.ethernet.Ethernet(buf)
# Make sure the Ethernet frame contains an IP packet
# EtherType (IP, ARP, PPPoE, IP6... see http://en.wikipedia.org/wiki/EtherType)
if eth.type != dpkt.ethernet.ETH_TYPE_IP6:
print 'Non IP Packet type not supported %s\n' % eth.data.__class__.__name__
continue
# Now unpack the data within the Ethernet frame (the IP packet)
# Pulling out src, dst, length, fragment info, TTL, and Protocol
ipv6 = eth.data
fh = dpkt.ip.IP_PROTO_FRAGMENT
ic = dpkt.ip.IP_PROTO_ICMP6
icmpv6 = ipv6.data
# get src and dst ip address
src_ip = socket.inet_ntop(AF_INET6, ipv6.src)
dst_ip = socket.inet_ntop(AF_INET6, ipv6.dst)
# Analyzing pcap file offline
#if packet.haslayer(IPv6) and pkt[IPv6].nh == 44 and dpkt.ip6.IP6FragmentHeader.nxt==60 and dpkt.ip6.IP6HopOptsHeader.nxt == 58:
if ipv6.v == 6 and ipv6.nxt==44:
print ipv6.IP6FragmentHeader.nxt
更新:当我使用 dpkt.ip6.IP6FragmentHeader 我得到这个错误
AttributeError:“str”对象没有属性“IP6FragmentHeader”
我想从这个数据包中获取分片头,它是 ICMPv6 Wireshark 数据包
