Ich nehme mal an da versucht jemand via SSH auf meinen Server zu gelangen. Hilft mir die IP nun weiter? Ist theplanet.com zwingend der ISP des Angreifers oder kann er diese vortäuschen? (d.h. es nützt nichts wenn ich mich an theplanet.com wende ?)
Kennt jemand eine Möglichkeit wie man solche Versuche unterbinden kann? z.B. die IP blocken nach x Fehlversuchen?
