| Description: |
Nast is a packet sniffer and a LAN analyzer based on Libnet and Libpcap. It can sniff in normal mode or in promiscuos mode the packets on a network interface. It dumps the headers of packets and the payload in ascii or ascii-hex format.
You can apply a filter (e.g. "src ip", "port 22"...).The data sniffed can be saved in a separated file. As analyzer tool, it can check for other NIC set in promisc mode, build the list of all hosts of the LAN, find a gate­way, perform a port scanning of a single/multiple host/s and catch daemon banner for the hosts of the LAN, follow the TCP data stream, reset a connection, and find out the link type (HUB or SWITCH).
