| 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! |
