VERSION. 0.12.3
DESCRIPTION. pmacct is a small set of passive network monitoring tools to account, classify, aggregate and export IPv4 and IPv6 traffic; a pluggable architecture allows to store collected network data into memory tables or SQL (MySQL, SQLite, PostgreSQL) databases and export them through NetFlow or sFlow protocols to remote collectors. pmacct supports fully customizable historical data breakdown, BGP correlation, sampling, filtering, tagging and triggers. Libpcap, Netlink/ULOG, sFlow v2/v4/v5 and NetFlow v1/ v5/v7/v8/v9 are supported, both unicast and multicast. It also supports replication of incoming NetFlow and sFlow datagrams. A client tool makes it easy to export data to tools like RRDtool, GNUPlot, Net-SNMP, MRTG, and Cacti. HOMEPAGE. http://www.pmacct.net/ DOWNLOAD. http://www.pmacct.net/pmacct-0.12.3.tar.gz CHANGELOG. + 'cos' aggregation primitive has been implemented providing support for 802.1p priority. Collection is supported via sFlow, libpcap and ULOG; export is supported via sFlow. + BGP daemon: TCP MD5 signature implemented. New 'bgp_daemon_md5_file' configuration directive is being added for the purpose of defining peers and their respective MD5 keys, one per line, in CSV format. The map is reloadable at runtime: existing MD5 keys are removed via setsockopt(), new ones are installed as per the newly supplied map. Sample map added in 'examples/bgp_md5.lst.example'. + BGP daemon: added support for RFC3107 (SAFI=4 label information) to enable receipt of labeled IPv4/IPv6 unicast prefixes. + nfprobe, sfprobe: introduced the concept of traffic direction. As a result, [ns]fprobe_direction and [ns]fprobe_ifindex configuration directives have been implemented. + [ns]fprobe_direction defines traffic direction. It can be statically defined via 'in' or 'out' keywords; values can also be dynamically determined through a pre_tag_map (1=input, 2=output) by means of 'tag' and 'tag2' keywords. + [ns]fprobe_ifindex either statically associate an interface index (ifIndex) to a given [ns]fprobe plugin or semi-dynamically via lookups against a pre_tag_map by means of 'tag' and 'tag2' keywords. + sfprobe: sfprobe_ifspeed configuration directive is introduced and aimed at statically associating an interface speed to an sfprobe plugin. + sfprobe: Switch Extension Header support added. Enabler for this development was support for 'cos' and in/out direction. Whereas VLAN information was already supported as an aggregation primitive. + sfprobe: added support for Counter Samples for multiple interfaces. Sampling function has been brought to the plugin so that Counter Samples can be populated with real bytes/packets traffic levels. ! nfprobe, sfprobe: send buffer size is now aligned to plugin_pipe_size, if specified, providing a way to tune buffers in case of sustained exports. ! fix, addr.c: pm_ntohll() and pm_htonll() routines rewritten. These are aimed at changing byte ordering of 64-bit variables. ! fix, BGP daemon: support for IPv6 global address/link-local address next-hops as part of MP_REACH_NLRI parsing. ! fix, cfg_handlers.c: bgp_daemon and bgp_daemon_msglog parsing was not correct, ie. enabled if specified as 'false'. Thanks to Brent Van Dussen for reporting the issue. ! fix, bgp.c: found a CPU hog issue caused by missing cleanup of the select() descriptors vector. ! fix, pmacct.c: in_iface/out_iface did erroneously fall inside a section protected by the "--disable-l2" switch. Thanks to Brent Van Dussen for reporting the issue. NOTES. None. Cheers, Paolo _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
