-+To tarpit connections to TCP port 80 destined for the current machine:
-+.IP
-+iptables -A INPUT -p tcp -m tcp --dport 80 -j TARPIT
-+.P
-+To significantly slow down Code Red/Nimda-style scans of unused address
-+space, forward unused ip addresses to a Linux box not acting as a router
-+(e.g. "ip route 10.0.0.0 255.0.0.0 ip.of.linux.box" on a Cisco), enable IP
-+forwarding on the Linux box, and add:
-+.IP
-+iptables -A FORWARD -p tcp -j TARPIT
-+.IP
-+iptables -A FORWARD -j DROP
-+.TP
-+NOTE:
-+If you use the conntrack module while you are using TARPIT, you should
-+also use the NOTRACK target, or the kernel will unnecessarily allocate
-+resources for each TARPITted connection. To TARPIT incoming
-+connections to the standard IRC port while using conntrack, you could:
-+.IP
-+iptables -t raw -A PREROUTING -p tcp --dport 6667 -j NOTRACK
-+.IP
-+iptables -A INPUT -p tcp --dport 6667 -j TARPIT

++Use the REJECT and DELUDE targets as a base to do a sudden or deferred

++Detects simple port scan attemps based upon the packet's contents. (This is
++different from other implementations, which also try to match the rate of new
++connections.) Note that an attempt is only discovered after it has been carried
++out, but this information can be used in conjunction with other rules to block
++the remote host's future connections. So this match module will match on the
++(probably) last packet the remote side will send to your machine.

++Match if the packet did not belong to any known TCP connection
++(Stealth/FIN/XMAS/NULL scan).
++.TP
++\fB--synscan\fR
++Match if the connection was a TCP half-open discovery (SYN scan), i.e. the
++connection was torn down after the 2nd packet in the 3-way handshake.
++.TP
++\fB--cnscan\fR
++Match if the connection was a TCP full open discovery (connect scan), i.e. the
++connection was torn down after completion of the 3-way handshake.
++.TP
++\fB--grscan\fR
++Match if data in the connection only flew in the direction of the remote side,
++e.g. if the connection was terminated after a locally running daemon sent its
++identification. (e.g. openssh)
++.PP
++NOTE: Some clients (Windows XP for example) may do what looks like a SYN scan,
++so be advised to carefully use xt_portscan in conjunction with blocking rules,
++as it may lock out your very own internal network.

++Captures and holds incoming TCP connections using no local
++per-connection resources. Connections are accepted, but immediately
++switched to the persist state (0 byte window), in which the remote
++side stops sending data and asks to continue every 60-240 seconds.
++Attempts to close the connection are ignored, forcing the remote side
++to time out the connection in 12-24 minutes.
++
++This offers similar functionality to LaBrea
++<http://www.hackbusters.net/LaBrea/> but doesn't require dedicated
++hardware or IPs. Any TCP port that you would normally DROP or REJECT
++can instead become a tarpit.
++
++To tarpit connections to TCP port 80 destined for the current machine:
++.IP
++iptables -A INPUT -p tcp -m tcp --dport 80 -j TARPIT
++.P
++To significantly slow down Code Red/Nimda-style scans of unused address
++space, forward unused ip addresses to a Linux box not acting as a router
++(e.g. "ip route 10.0.0.0 255.0.0.0 ip.of.linux.box" on a Cisco), enable IP
++forwarding on the Linux box, and add:
++.IP
++iptables -A FORWARD -p tcp -j TARPIT
++.IP
++iptables -A FORWARD -j DROP
++.TP
++NOTE:
++If you use the conntrack module while you are using TARPIT, you should
++also use the NOTRACK target, or the kernel will unnecessarily allocate
++resources for each TARPITted connection. To TARPIT incoming
++connections to the standard IRC port while using conntrack, you could:
++.IP
++iptables -t raw -A PREROUTING -p tcp --dport 6667 -j NOTRACK
++.IP
++iptables -A INPUT -p tcp --dport 6667 -j TARPIT
