ho installato fail2ban, sul mio mailserver, funziona con la policy drop, ma non riesco a implementare il TARPIT:
# Option: actionban
# Notes.: command executed when banning an IP. Take care that the
# command is executed with Fail2Ban user rights.
# Tags: <ip> IP address
# <failures> number of failures
# <time> unix timestamp of the ban time
# Values: CMD
#
actionban = iptables -I fail2ban-<name> 1 -s <ip> -j DROP
#actionban = iptables -I fail2ban-<name> 1 -s <ip> -j TARPIT
Avete qualche consiglio?
ciao
