-Allows you to dynamically create a list of IP addresses and then match
-against that list in a few different ways.
-
-For example, you can create a `badguy' list out of people attempting
-to connect to port 139 on your firewall and then DROP all future
-packets from them without considering them.
-.TP
-.BI "--name " "name"
-Specify the list to use for the commands. If no name is given then 'DEFAULT'
-will be used.
-.TP
-[\fB!\fR] \fB--set\fR
-This will add the source address of the packet to the list. If the
-source address is already in the list, this will update the existing
-entry. This will always return success (or failure if `!' is passed
-in).
-.TP
-[\fB!\fR] \fB--rcheck\fR
-Check if the source address of the packet is currently in
-the list.
-.TP
-[\fB!\fR] \fB--update\fR
-Like \fB--rcheck\fR, except it will update the "last seen" timestamp if it
-matches.
-.TP
-[\fB!\fR] \fB--remove\fR
-Check if the source address of the packet is currently in the list and
-if so that address will be removed from the list and the rule will
-return true. If the address is not found, false is returned.
-.TP
-[\fB!\fR] \fB--seconds \fIseconds\fR
-This option must be used in conjunction with one of \fB--rcheck\fR or
-\fB--update\fR. When used, this will narrow the match to only happen
-when the address is in the list and was seen within the last given
-number of seconds.
-.TP
-[\fB!\fR] \fB--hitcount \fIhits\fR
-This option must be used in conjunction with one of \fB--rcheck\fR or
-\fB--update\fR. When used, this will narrow the match to only happen
-when the address is in the list and packets had been received greater
-than or equal to the given value. This option may be used along with
-\fB--seconds\fR to create an even narrower match requiring a certain
-number of hits within a specific time frame.
-.TP
-\fB--rttl\fR
-This option must be used in conjunction with one of \fB--rcheck\fR or
-\fB--update\fR. When used, this will narrow the match to only happen
-when the address is in the list and the TTL of the current packet
-matches that of the packet which hit the \fB--set\fR rule. This may be
-useful if you have problems with people faking their source address in
-order to DoS you via this module by disallowing others access to your
-site by sending bogus packets to you.
-.P
-Examples:
-.IP
-# iptables -A FORWARD -m recent --name badguy --rcheck --seconds 60 -j DROP
-
-# iptables -A FORWARD -p tcp -i eth0 --dport 139 -m recent --name badguy --set -j DROP
-.P
-Official website (http://snowman.net/projects/ipt_recent/) also has
-some examples of usage.
-
-/proc/net/ipt_recent/* are the current lists of addresses and information
-about each entry of each list.
-
-Each file in /proc/net/ipt_recent/ can be read from to see the current list
-or written two using the following commands to modify the list:
-.TP
-echo xx.xx.xx.xx > /proc/net/ipt_recent/DEFAULT
-to Add to the DEFAULT list
-.TP
-echo -xx.xx.xx.xx > /proc/net/ipt_recent/DEFAULT
-to Remove from the DEFAULT list
-.TP
-echo clear > /proc/net/ipt_recent/DEFAULT
-to empty the DEFAULT list.
-.P
-The module itself accepts parameters, defaults shown:
-.TP
-.BI "ip_list_tot=" "100"
-Number of addresses remembered per table
-.TP
-.BI "ip_pkt_list_tot=" "20"
-Number of packets per address remembered
-.TP
-.BI "ip_list_hash_size=" "0"
-Hash table size. 0 means to calculate it based on ip_list_tot, default: 512
-.TP
-.BI "ip_list_perms=" "0644"
-Permissions for /proc/net/ipt_recent/* files
-.TP
-.BI "debug=" "0"
-Set to 1 to get lots of debugging info

+# iptables -A FORWARD -m recent --name badguy --rcheck --seconds 60 -j DROP
+
+# iptables -A FORWARD -p tcp -i eth0 --dport 139 -m recent --name badguy --set -j DROP
+.P
+Official website (http://snowman.net/projects/ipt_recent/) also has
+some examples of usage.
+
+/proc/net/ipt_recent/* are the current lists of addresses and information
+about each entry of each list.
+
+Each file in /proc/net/ipt_recent/ can be read from to see the current list
+or written two using the following commands to modify the list:
+.TP
+echo xx.xx.xx.xx > /proc/net/ipt_recent/DEFAULT
+to Add to the DEFAULT list
+.TP
+echo -xx.xx.xx.xx > /proc/net/ipt_recent/DEFAULT
+to Remove from the DEFAULT list
+.TP
+echo clear > /proc/net/ipt_recent/DEFAULT
+to empty the DEFAULT list.
+.P
+The module itself accepts parameters, defaults shown:
+.TP
+.BI "ip_list_tot=" "100"
+Number of addresses remembered per table
+.TP
+.BI "ip_pkt_list_tot=" "20"
+Number of packets per address remembered
+.TP
+.BI "ip_list_hash_size=" "0"
+Hash table size. 0 means to calculate it based on ip_list_tot, default: 512
+.TP
+.BI "ip_list_perms=" "0644"
+Permissions for /proc/net/ipt_recent/* files
+.TP
+.BI "debug=" "0"
+Set to 1 to get lots of debugging info
