Честно скопи-пастил отсюда 🙂
Новые таржеты для iptables:
- CHAOS: randomly use REJECT, DELUDE or TARPIT targets.
This will fool network scanners by returning random results - DELUDE: always reply to a SYN by a SYN-ACK. This will fool TCP half-open discovery
- DHCPADDR: replace a MAC address from and to a VMware host
- IPMARK: mark a packet, based on its IP address
- LOGMARK: log packet and mark to syslog
- SYSRQ: trigger a sysreq over the network (sending a saK over the network looks like a real funny ida
- TARPIT: try to slow down (or DoS) remote host by capturing the session and holding it for a long time, using a 0-bytes TCP window. Run that on port 25 if you have no mail server to slow down spammers 😉
Новые совпадения (matches) для iptables:
condition: match on boolean value stored in /proc/net/nf_condition/name
dhcpaddr: match the DHCP Client Host address in a DHCP message
fuzzy: match a rate limit based on a fuzzy logic controller
geoip: match a packet by its source or destination country
ipp2p: match (certain) p2p protocols
quota2: named counters
pknock: port knock
…. и другие.
У себя собрал, но запустить в работу еще руки не дошли.
Ай шайтанэ 🙂
