NeTAMS - Network Traffic Accounting and Monitoring Software.
netams [-dlq] [ -f <config-file> ]
NeTAMS is a Network Traffic Accounting and Monitoring Software. It works as a daemon for FreeBSD, Linux and Solaris operating systems. Supported traffic information sources are tee/divert/ip_queue/libpcap/netflow v5; storages are BerkleyDB/MySQL/PostgresSQL. Various aggregation, vizualisation and notification ways are implemented. Authorization, quotas, bandwidth control, flexible accounting and blocking policies are also here.
-d do not become daemon -f config-file config-file specifies an alternate configuration file to use. -l turn logging to file on -L turn logging to syslog on -p pid-file pid-file specifies an alternate pid file to use. -P do not create a pid file (by default, pid file created while options -l or -L used) -q do not produce any output
You can run NeTAMS in three different modes depending on data source type: libpcap allows you to capture all traffic on specified interface, exactly as tcpdump does. netflow collects all NetFlow v5 UDP packets coming from Cisco router or external flow producer like flowprobe/ipfw2netflow/ng_netflow. You don't need in any additional system features to run libpcap or netflow accounting, but you cannot do any filtering with these data sources. divert or ipq captures all IP traffic going via your UNIX router, and you need to prepare system for that. If you system is FreeBSD, your kernel configuration must have: options IPFIREWALL options IPDIVERT otherwise you will be not able to pass data packets to the program. Type "dmesg" and have a look. If you have Linux, you must use kernels 2.4.* or above, and iptables. Your system must have netfilter package and libipq library properly installed; both are typically not in a default installation. You should visit http://www.netfilter.org site, read the documentation, download, install it and rebuild a kernel. Or at least check 'modprobe ip_queue'. For a serious work, install the SQL database, http://www.mysql.com or http://postgresql.org, and do not use unix hash database from libdb (also supported by NeTAMS).
SIGHUP or SIGUSR1 will cause log file to be closed and opened again. Useful for logrotate. SIGQUIT will terminate the program safely.
