Linux Network IP Accounting

Nov 10, 2010, 14:33 (0 Talkback[s])

[ Thanks to An Anonymous Reader for this link. ]

"I need to know how much data are transmitted on my ppp0 network or eth0 Internet links? How do I set IP accounting by address such as 123.1.2.3 and 123.1.2.4? How do I set IP accounting per Apache virtual domain? How do I set accounting by service port (http, smtp) and protocol (tcp, udp, icmp)? How do I record how much traffic each of the clients computer is using?

"You don't have to install anything special. The Linux kernel comes with IP accounting which is part of iptables. It is the part of Linux firewall software. At firewall level you can filter traffic and configure IP accounting. Linux kernel collects lots of information about the network traffic and same can be used for IP accounting. You can also use 3rd party software too."
