snoop

Network packet sniffer. SunOS equivalent of tcpdump.

• Capture packets on a specific network interface:

snoop -d {{e1000g0}}

• Save captured packets in a file instead of displaying them:

snoop -o {{filename}}

• Display verbose protocol layer summary of packets from a file:

snoop -V -i {{filename}}

• Capture network packets that come from a hostname and go to a given port:

snoop to port {{port}} from host {{hostname}}

• Capture and show an hex-dump of network packets exchanged between two IP addresses:

snoop -x0 -p4 {{ip_address_1}} {{ip_address_2}}
