Should I do something on my Debian 10 side or the Tor 0.3.5.8 itself is able to mitigate most of the DoS attacks?


Background:

  • Yesterday I have set up my new relay.

  • I have the overall maximum bandwidth of 30 Mbit down / 30 Mbit up.

  • I monitor the relay on one display with Nyx:

    tor - nyx

  • Snippet from the picture:
