Getting Started
Step 1
Set up a udp echo server at the host you want to ping.
There are many ways of doing this, my favourite way is:
socat -v UDP-LISTEN:4000,fork PIPE
Now a echo server is listening at port 4000.
Note
If you dont have socat, use apt install socat or yum install socat, you will get it.
Step 2
Ping you server.
Assume 44.55.66.77 is the IP of your server.
./udpping.py 44.55.66.77 4000
Done!
Now UDPping will generate outputs as a normal ping, but the protocol used is UDP instead of ICMP.
Advanced Usage
root@raspberrypi:~# ./udpping.py
usage:
this_program <dest_ip> <dest_port>
this_program <dest_ip> <dest_port> "<options>"
options:
LEN the length of payload, unit:byte
INTERVAL the seconds waited between sending each packet, as well as the timeout for reply packet, unit: ms
examples:
./udpping.py 44.55.66.77 4000
./udpping.py 44.55.66.77 4000 "LEN=400;INTERVAL=2000"
./udpping.py fe80::5400:ff:aabb:ccdd 4000
