tcap

Uses pcap to inspect tchannel traffic over a network interface.

  Usage: tcap [options]

  Options:

    -h, --help                 output usage information
    -V, --version              output the version number
    -i --interface [interface  network interface name for capture (defaults to first with an address)
    -f --filter [filter]       packet filter in pcap-filter(7) syntax (default: all TCP packets on port 4040)
    -b --buffer-size [mb]      size in MiB to buffer between libpcap and app (default: 10)
    -h --hex                   show hex dumps for all packets
    -j --json                  show JSON dumps for all parsed frames
    --color                    enables colors if not connected to a tty.
    --no-color                 disables colors if connected to a tty.

Example

To monitor tchannel traffic on ports 4040 and 4041 over the loopback and first ethernet interface on a Mac:

tcap -i lo0 -i en0 -p 4040 -p 4041

Note that the interface names differ on other systems. Use ifconfig.
