Free pmacct how to software for linux

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.

Aggregates can be stored into memory tables, SQL databases (MySQL or PostgreSQL) or simply printed to stdout. Data is collected from the network either using libpcap (and optionally promiscuous mode) or reading NetFlow v1/v5/v7/v8/v9 and sFlow v2/v4/v5 datagrams, both unicast and multicast.

IP accounting is the key in ISP/IXP network operations like billing, graphing network resources usage, live or historical traffic analysis, handling of network thresholds, provisioning and SLA monitoring. SNMP counters sometime are not this useful because of their coarse granularity.

Finer granularities become valuable if data are historical and match logical entities of interest such as Autonomous System Numbers, departmental or customer network chunks, specific traffic flows, etc. Further, 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 advanced filtering and sampling capabilities are requirements that cannot be missed anymore.

Either using memory or SQL tables as backend storage, pmacct can easily feed data to tools like MRTG, RRDtool, Cacti and Gnuplot among the others. A little scripting abilities are required to glue pmacct with external tools and a number of sample scripts and some tutorials are already available.

Scriptol to Php Compiler is a scriptol program that may be interpreted by the Php interpreter and it may be also compiled either to C++ or directly as an executable.

The Php interpreter is required by solp (download it at www.php.net or get it on the Scriptol CD).

Installation:

It is better to install Scriptol at root of a disk, for example:
/home/user/scriptolp

Once the archive is extracted into the scriptolp directory, you have just to go to this directory from the console to run the compiler.

To use the compiler at command line from any directory, you have to put the compilers into the path, in the usr directory for exemple, or any directory assigned to the path variable (see .bashrc or equivalent). You may also add the scriptol directory to list of paths. Before to use the compiler, you have to read the licence, in the doc directory: licence.html.

Usage:

Type the source of your program in a text editor and save it as mysource.sol or any other name with the sol extension.

Then just type:

./solp mysource

To know the compilers options, type solp without argument, at command line.

Examples:

Type from the main scriptol directory:
./solp demos/helloyou

C to C++ is a Python script that converts C code to C++ code.

The main program is ctocpp.py that performs successive stages for converting C to C++. A script, ctocpp gives it as parameter to the python interpreter with options you add.

The archive also includes scripts that may help you:

- mover.py changes the location of a project.
- search.py performs searches and replacements.
- mkheader.py corrects a header file.

The C to C++ program with all the python sources is under the GNU GPL license,
that minds you may use it and distribute it freely, providing the copyright is unchanged.

See at the COPYING file for details. This doesnt mean GNU encourages you to convert your C sources to C++. In fact, most of the tools here included may help C programmers outside C++ conversion.

Installing:

Type:
./configure
./setup
mkdoc ...this will generate an html and info manuals.

Intro to Bash Programming HOWTO is a bash programming tutorial.
The Intro to Bash Programming HOWTO is meant for newbies who wish to learn how to write shell scripts for bash, the GNU Boure-Again shell.
It contains several samples. It is very early in its development, but it is hoped that some people might find it useful.
Enhancements:
- New translations included and minor correcitons.
