ntopng网络流量实时监控

　　ntopng is the next generation version of the original ntop, a network traffic probe that monitors network usage. ntopng is based on libpcapand it has been written in a portable way in order to virtually run on every Unix platform, MacOSX and on Windows as well.

　　ntopng – yes, it’s all lowercase – provides a intuitive, encrypted web user interface for the exploration of realtime and historical traffic information.

Main Features

• Sort network traffic according to many criteria including IP address, port, L7 protocol, throughput, Autonomous Systems (ASs)
• Show realtime network traffic and active hosts
• Produce long-term reports for several network metrics including throughput and application protocols
• Top talkers (senders/receivers), top ASs, top L7 applications
• Monitor and report live throughput, network and application latencies, Round Trip Time (RTT), TCP statistics (retransmissions, out of order packets, packet lost), and bytes and packets transmitted
• Store on disk persistent traffic statistics to allow future explorations and post-mortem analyses
• Geolocate and overlay hosts in a geographical map
• Discover application protocols (Facebook, YouTube, BitTorrent, etc) by leveraging on nDPI, ntop Deep Packet Inspection (DPI) technology
• Characterise HTTP traffic by leveraging on characterisation services provided by Google and HTTP Blacklist.
• Analyse IP traffic and sort it according to the source/destination.
• Report IP protocol usage sorted by protocol type
• Produce HTML5/AJAX network traffic statistics.
• Full support for IPv4 and IPv6
• Full Layer-2 support (including ARP statistics)
• GTP/GRE detunnelling
• Support for MySQL, ElasticSearch and LogStash export of monitored data
• Interactive historical exploration of monitored data exported to MySQL
• Alerts engine to capture anomalous and suspicious hosts
• SNMP v1/v2c support and continuous monitoring of SNMP devices

　　当你在本地网络监控网络流量，根据流量大小、监控平台/接口、数据库类型等等，可以有许多不同的选择。ntopng是一套开源（遵循GPLv3协议）网络流量分析解决方案，提供基于web界面的实时网络流量监控。支持跨平台，包括Linux和MacOS X。ntopng类似于RMON远端网络监控代理，具有内置的Web服务能力，使用Redis键值服务按时间序列存储统计信息。你可以在任何指定的监控服务器上安装ntopng，只需使用任一web浏览器，就能实时访问服务器上的流量报告了。

基于源码编译（内网环境）

01、编译底层库

yum install -y gcc gcc-c++

yum install -y libpcap  libpcap-devel  

yum install -y  libxml2 libxml2-devel

yum install -y glib2 glib2-devel

yum install -y mysql mysql-server

yum install -y git autoconf  automake gmake

yum install -y libcurl-devel

yum install sqlite sqlite-devel

yum install libtool 

02、安装redis

官网：https://redis.io/

rpm -ivh redis-2.4.10-1.el6.x86_64.rpm

配置：/etc/redis.conf  

service redis start

[root@100-lab nt]# ss -ln
State      Recv-Q Send-Q                Local Address:Port                  Peer Address:Port 
LISTEN     0      128                       127.0.0.1:6379                             *:*     
LISTEN     0      128                              :::22                              :::*     
LISTEN     0      128                               *:22                               *:*     
LISTEN     0      100                             ::1:25                              :::*     
LISTEN     0      100                       127.0.0.1:25                               *:*     

03、编译ntopng

官网：http://www.ntop.org/products/traffic-analysis/ntop/

ntopng-2.2.tar.gz 

下载：http://pan.baidu.com/s/1dEJnzUD

解压   tar zxf ntopng-2.2.tar.gz

./autogen.sh   #编译git,生成configure

./configure     #

./gmake         #编译

make install   #安装 /usr/local/ntopng

04、配置文件

vim /etc/ntopng.conf

#进程号
-G=/var/tmp/ntopng.gid

# 指定监听本地的哪些网段
--local-networks=192.168.100.0/24,192.168.200.0/24
# 指定监听哪张网卡
--interface=eth0
# 指定监听哪个http端口，用于web管理
--user=root
--http-port=3000   #http://ip:3000  认证用户admin/admin

05、启动ntopng

/etc/rc.d/init.d/redis start
启动redis
/usr/local/bin/ntopng /etc/ntopng/ntopng.conf &
启动ntopng并在后台运行
访问http://192.168.100.166:3000/，输入默认用户名和密码admin admin

06、错误解决

00：

[root@100-lab ntopng-2.2]# ./autogen.sh 
./autogen.sh: line 11: git: command not found
./autogen.sh: line 14: git: command not found

#解决方案

yum install sqlite sqlite-devel

yum install -y git autoconf  automake gmake
