pmacct

pmacct RPM with nDPI support for CentOS 7.

This is work is based on RPM from Lux Repository.

How to build

nDPI 3.4

The build must be done on a NethServer 7.

First, compile ndpi-dev rRPM because pmacct requires nDPI devel headers.

yum install gcc-c++ automake autoconf  libpcap-devel libtool numactl-devel jason-c-devel -y
wget https://github.com/ntop/nDPI/archive/refs/tags/3.4.tar.gz
tar xvzf 3.4.tar.gz
ln -s nDPI-3.4/ nDPI
cd nDPI-3.4/
./autogen.sh && ./configure && make && make install
cd packages/rpm
./configure && make

pmacct

Move to root directory, then prepare the evironment to build rpms:

yum install podman git
mkdir ~/bin
curl https://raw.githubusercontent.com/NethServer/nethserver-makerpms/master/install.sh | bash

Build pmacct:

export PATH=$PATH:~/bin
git clone https://github.com/gsanchietti/pmacct.git
cd pmacct
YUM_ARGS="--enablerepo=nethserver-testing" ~/bin/makerpms pmacct.spec

Install

You need to force install to avoid dependency errors:

rpm -Uvh --nodeps pmacct-*.rpm

Usage

Create this sqlite file, eg schema.sql:

CREATE TABLE acct_v5 (
    agent_id INT(8) NOT NULL DEFAULT 0,
    class CHAR(16) NOT NULL DEFAULT ' ',
    class_id CHAR(16) NOT NULL DEFAULT ' ',
    mac_src CHAR(17) NOT NULL DEFAULT '0:0:0:0:0:0',
    mac_dst CHAR(17) NOT NULL DEFAULT '0:0:0:0:0:0',
    vlan INT(4) NOT NULL DEFAULT 0,
    ip_src CHAR(45) NOT NULL DEFAULT '0.0.0.0',
    ip_dst CHAR(45) NOT NULL DEFAULT '0.0.0.0',
    src_port INT(4) NOT NULL DEFAULT 0,
    dst_port INT(4) NOT NULL DEFAULT 0,
    ip_proto CHAR(6) NOT NULL DEFAULT 0, 
    tos INT(4) NOT NULL DEFAULT 0, 
    packets INT NOT NULL,
    bytes BIGINT NOT NULL,
    flows INT NOT NULL DEFAULT 0,
    stamp_inserted DATETIME NOT NULL DEFAULT '0000-00-00 00:00:00',
    stamp_updated DATETIME,
    PRIMARY KEY (agent_id, class, class_id, mac_src, mac_dst, vlan, ip_src, ip_dst, src_port, dst_port, ip_proto, tos, stamp_inserted)
);

Then load it:

sqlite3 /etc/pmacct/pmacct.db < schema.sql

Example of pmacctd.conf:

! debug: true
daemonize: false
!
! libpcap daemon configs
!
pcap_interface: eth0
!
! Plugins definitions
!
plugins: sqlite3[foo],  memory[all]
!
! 'foo' plugin configuration
!
aggregate[foo]: src_host, dst_host, src_port, dst_port, proto, tos, class
sql_db[foo]: /etc/pmacct/pmacct.db
sql_table_name[foo]: acct
sql_table_version[foo]: 5 
! sql_table_version[foo]: 2 
! sql_table_version[foo]: 3 
sql_refresh_time[foo]: 60
sql_history[foo]: 1m 
sql_history_roundoff[foo]: m

aggregate[all]: dst_host, src_host
!imt_path[all]: /tmp/pipe.memory

Execute the daemon:

cd /etc/pmacct
pmacctd -f pmacctd.conf

Example of data:

# sqlite3 /etc/pmacct/pmacct.db "select * from acct_v5;"
