name : dddos_example.txt Demonstrations of dddos.py, the Linux eBPF/bcc version. This tracks ip_rcv function (using kprobe) and elapsed time between received packets to detect potential DDOS attacks. The following steps illustrates the usage of dddos : 1 - Start dddos.py : # ./dddos.py DDOS detector started ... Hit Ctrl-C to end! TIME(s) MESSAGE 2 - Launch hping3 (or any other flooder) in another terminal as shown below: # hping3 localhost -S -A -V -p 443 -i u100 3 - dddos.py triggers alerts and reports a DDOS attack: DDOS detector started ... Hit Ctrl-C to end!
