FlowScan 1.006
FlowScan is a network analysis and reporting tool. more>>
FlowScan is a network analysis and reporting tool.[ COPYRIGHT=1]
Enhancements:
- The CampusIO and SubNetIO reports were enhanced with a new optional configuration directive: TopN. When defined, this directive causes ``Top Talker reports to be produced. These HTML reports contain the most active (i.e. ``top) source and destination addresses.
- The CampusIO and SubNetIO reports were enhanced to record the number of local IP addresses that where active for each network and subnet into the RRD files. This enables users to estimate the number of active hosts hosts over time, detect ``scans which systematically sweep across network address space, and to calculate the average bytes, packets, and flows per host.
- The template Makefile used to produce the graphs was enhanced to allow the inclusion of ``events in the graphs, similarly to what can be done with Cricket. This allows you to label events such as configuration changes and outages to discover correlations with traffic measurement.
- Two new utilities suitable for stand-alone use, are included. ip2hostname converts IP addresses to their respective hostnames. event2vrule adds ``events to rrdtool graphs.
- Added support for LFAP (Lightweight Flow Accouting Protocol) used by Riverstone and Enterasys (formerly Cabletron) routers. This currently requires slate (from http://www.nmops.org) and lfapd by Steven Premeau . lfapd produces time-stamped raw flow files in the same cflowd-defined format that is processed by FlowScan.
- Added the ability for the CampusIO report to identify outbound flows based solely on the flows destination IP address. While this is less trustworthy than using NextHops or OutputIfIndexes, it is now the default and will be useful for environments where the flow nexthop or output ifIndex values are not meaningful.
- The CampusIO report contains a new experimental feature which reads a BGP routing table, and therefore can determine which Autonomous systems source, transit, or sink most of your institutions traffic. The CampusIO report was enhanced with new optional configuration directives: BGPDumpFile, TopN, ReportPrefixFormat. When properly defined, these directives cause CampusIO to create tabular HTML reports named {origin|path}_{in|out}.html under OutputDir after analyzing each raw flow file. These reports show the ``top Autonomous Systems with which your site exchanges traffic.
- A WebProxyIfIndex directive was added to the CampusIO report. This allows one to specify the index of the interface to which HTTP traffic is being transparently redirected. This enables FlowScan to properly count HTTP flows even though NetFlow v5 does not accurately report the nexthop value for flows which are transparently redirected via a Cisco route-map.
- CampusIO now contains a fix for a bug introduced in FlowScan-1.005 which would sometimes cause perl to abort with this message: patricia.c:645: patricia_lookup: Assertion `prefix failed.

pmacct 0.11.4
pmacct is a small set of IPv4/IPv6 accounting and aggregation tools. more>>
pmacct is a small set of passive network monitoring tools to measure, account and aggregate IPv4 and IPv6 traffic; aggregation revolves around the key concept of primitives (VLAN id, source and destination MAC addresses, hosts, networks, AS numbers, ports, IP protocol and ToS/DSCP field are supported) which may be arbitrarily combined to build custom aggregation methods; support for historical data breakdown, triggers and packet tagging, filtering, sampling.
Aggregates can be stored into memory tables, SQL databases (MySQL or PostgreSQL) or simply pushed to stdout. Data is collected either using libpcap (and optionally promiscuous mode of the listening interface) or reading Netflow v1/v5/v7/v8/v9 packets coming from the network.
IP accounting is the key for a range of operations like billing, pricing models application, live or historical traffic analysis, network thresholds handling, provisioning and SLA monitoring. Taking SNMP counters from network equipments sometime is not this useful because of their coarse granularity.
Finer granularities become valuable if available data match logical entities of interest such as Autonomous Systems, either departmental or customer networks, specific traffic flows, etc. and can be encapsulated into arbitrary timeframes (also referred as
However, actual large-scale networks are able to produce, in very short times, high amounts of data that become quickly difficult to be processed in a meaningful way. In this context, traffic aggregation and filtering capabilities are requirements that cannot be missed.
Either using memory or SQL tables as backend storage, pmacct can also easily feed data to tools like MRTG, RRDtool and Gnuplot among the others. A little scripting abilities are required to glue pmacct with external tools and a few sample scripts are already included.
Enhancements:
- Support for TCP flags has been introduced.
- Flags are ORed on a per-aggregate basis.
- A new nfacctd_sql_log directive enables the use of NetFlows First and Last Switched values as timeslot delimiters.
- sfprobe and nfprobe plugins are now able to propagate tags to remote collectors through sFlow v5 and NetFlow v9 protocols.
- pmacct memory client features a new -T command line switch to output either TopN statistics.
- The pre_tag_map_entries configuration directive now allows you to dynamically allocate the Pre-Tagging map.
- There are miscellaneous bugfixes.
