Hi all, Currently I am working on Ip accounting in linux. My system is Redhat 9.0 with iptables v1.2.7a This redhat is doing Squid-Caching/ Nat/ Bandwidth management with tc/ Real ip forwarding. I want to do Ip accounting of upload and download. I want to know how much per ip bandwidth consumption is ? As i m doing source nat and Real ip forwarding, FORWARD chain will have bytes counters. So FORWARD chain will give the correct figure of how much the ip has used the bandwidth ??? I dont want to create new chain, I want to collect the data from INPUT/OUTPUT/FORWARD chains if that are accurate. Awaiting for help.. Excuse me for my English.
