-+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
