+ depends on IP_NF_IPTABLES && PROC_FS
+ help
+ This match is used for accounting traffic for all hosts in
+ defined network/netmask.
+
+ Features:
+ - long (one counter per protocol TCP/UDP/IMCP/Other) and short statistics
+ - one iptables rule for all hosts in network/netmask
+ - loading/saving counters (by reading/writting to procfs entries)
+
+ Example usage:
+
+ account traffic for/to 192.168.0.0/24 network into table mynetwork:
+
+ # iptables -A FORWARD -m account --aname mynetwork --aaddr 192.168.0.0/24
+
+ account traffic for/to WWW serwer for 192.168.0.0/24 network into table
+ mywwwserver:
+
+ # iptables -A INPUT -p tcp --dport 80
+ -m account --aname mywwwserver --aaddr 192.168.0.0/24 --ashort
+ # iptables -A OUTPUT -p tcp --sport 80
+ -m account --aname mywwwserver --aaddr 192.168.0.0/24 --ashort
+
+ read counters:
+
+ # cat /proc/net/ipt_account/mynetwork
+ # cat /proc/net/ipt_account/mywwwserver
+
+ set counters:
+
+ # echo "ip = 192.168.0.1 packets_src = 0" > /proc/net/ipt_account/mywwserver
