Since of version 1.7 there is also a CLI (command line interface) version of packETH. It doesn’t have many features but helps you to do some automated testing.

INSTALLATION:

1. 1)download and extract the source
   

2. 2)go into cli subdir
   

3. 3)type make
   

4. 4)if all the libraries are available, it will compile
   

Usage: packETHcli -i <interface> -m <mode> [-d <delay> -n <number of packets> [-s <startsize stopsize stepsize] -p period] -f <file>

-m <1,2,3>    - 1: send one packet (builder mode), no further options

                     - 2: send sequence of one packet (Gen-b mode)

                                -d <us, 0> - delay between packets in micro seconds

                                    (-1 for maximum speed without counters, 0 for max speed with counters)

                                -n <number, 0> - number of packets to send or 0 for infinite

                                -s "<startsize stopsize stepsize>"

                                -p <period between steps>

                     - 3: send sequence packets (Gen-s mode) - not yet done...

                                                                                                    

-f <file name> - file name where packet is stored in pcap format

                                                                                                    

Examples:                                                                                           

                                                                                                    

  ./packETHcli -i lo -m 1 -f packet1.pcap                  

                     - send packet1.pcap once on lo

  ./packETHcli -i eth0 -m 2 -d 1000 -n 300 -f packet2.pcap  

                     - send packet2.pcap 300 times with 1000 us (1ms) between them 

  ./packETHcli -i eth0 -m 2 -d -1 -n 0 -f packet2.pcap  

                     - send packet2.pcap at max speed, infinite times, no counters

  ./packETHcli -i eth0 -m 2 -d 0 -n 0 -f packet2.pcap  

                     - send packet2.pcap at max speed, infinite times, with counters

  ./packETHcli -i eth1 -m 2 -d 0 -n 0 -s "1000 1500 100" -p 10 -f packet3.pcap  

                    - send 10 times packet2.pcap at max speed, start with packet length of 1000 bytes

                    than increase packet length by 100 bytes, send another 10 packets... till 1500 bytes

  ./packETHcli -i eth0 -m 2 -d 100 -n 0 -s "8500 8500" -f packet2.pcap         

1.                    - send packet2.pcap infinite times with 300us between them with the size of 8500
   

2.                     bytes (even if packet2 is longer)
