Streaming packet header types to the command-line.
This command-line application is built with Command Lion and PacketGen.
$ gem install packet_head
To start capturing packets, the capture command is the only required command.
$ packet_head capture
Eth - IP - TCP
Eth - IP - UDP
Eth - IP - UDP - DNS
Eth - IP - ICMP
Eth - Dot1x
Eth - IPv6 - ICMPv6
Eth - ARP
Eth - IPv6 - ICMPv6
Eth - IP
...Explictly specify the interface to capture on.
$ packet_head capture eth0
The options for the capture command has several options: snaplen, promisc, buffer that all have default arguments if not specified.
$ packet_head capture eth0 snaplen 65535 promisc true buffer 1
You can also read a pcap/pcapng file's headers.
$ packet_head read name.pcap
Without any argument, the application defaults to a help menu.
