SCREENSHOTS:
Sniffer4J
DESCRIPTION:
Sniffer4J is a java packet capture and manipulation tool that allows full analysis of a network.
It is built upon pcap libs (winpcap, and libpcap) and can run in Windows and most Linux flavors.
The current stable version (2.0) provides shared libraries (.dll and .SO) compiled and tested for both x86 and x64 architectures.
Sniffer4J work’s by parsing packets in a comprehensive Pdu format. Each Pdu encapsulates the next one, making easy to navigate through the Frame.
Frames can be forged in the same manner allowing them to be injected in the network.
Sniffer4J support several protocols including:
* Ethernet I & II (including LLC and SNAP frames)
* Vlan (802.1Q)
* Arp
* Ipv4, Ipv6, (including options)
* Next Header for IpV6
* Ipsec
* TCP (including options)
* Udp
* Icmp (including RFC 2461 and Ipv6)
* Lldp
* Ipx
And more to come…
Remember: If you don’t test your network, some else will…
