Install Ntop monitoring network software
Ntop:
Ntop is a network traffic monitoring tool that uses ntop to display network usage in a more intuitive and detailed manner than other network management software. Ntop can even list the network bandwidth utilization of each node computer. It is a flexible and fully functional tool for monitoring and solving Lan problems. especially when ntop and nprobe are used in combination, its functions are more significant. It also provides command line input and web pages and can be applied to embedded web services.
Ntop mainly provides the following functions:
Automated Identification of useful information from the network;
Convert intercepted data packets into a format that is easy to recognize;
Analyze communication failures in the network environment
Testing the time and process of network communication

1. build the environment required for ntop.
1) configure yum
# Vi/etc/yum. repos. d/CentOS-Media.repo modify configuration file
C5-media
Name = CentOS-$ releasever-Media
Baseurl = file: // media/CentOS/
File: // mnt/cdrom/change to the disk mount location
File: // media/cdrecorder/
# Mount/dev/cdrom/mnt/cdrom/Attach a CD
# Yum list you can use this command to verify whether the mount is successful. this command lists all RPMs.
2) install the apache service
Install with yum
# Yum install httpd *
 
Total download size: 7.2 M
Is this OK [y/N]: whether to install y, select Y
 
3) install other dependent packages
The installation method is the same and will not be repeated here
Yum install freetype *
Yum install libpng *
Yum install libpcap *
Yum install gdbm *
Yum install libart_lgpl *
# Yum install libtool *
# Yum install automake *
4) install rrdtool-1.2.27.tar.gz
This package can be installed only after the above package is installed. Otherwise, an error message is returned.
# Tar-zxmf rrdtool-1.2.27.tar.gz decompression
#./Configure -- prefix =/usr/local/rrdtool pre-compilation configuration
Make & make install compile and install
 
II. install Ntop
# Tar-zxmf ntop-3.3.7.tar.gz decompression
#./Autogen. sh
#./Configure -- prefix =/usr/local/ntop pre-compilation configuration
# Make & make install compile and install
# Groupadd ntop create ntop Group
# Useradd ntop-g ntop window server an ntop user and add it to the ntop Group
# Chown-R ntop: ntop/usr/local/ntop
# Mkdir/var/ntop create ntop data storage directory
Chown-R ntop: ntop/var/ntop/set permissions
# Cd/usr/local/ntop/bin/find the ntop execution script
 
#./Ntop-A set the password
3. start the service and verify the result.
# Service httpd restart start the apache service first
# Cd/usr/local/ntop/bin/find the ntop execution script
#./Ntop-P/var/ntop/-I eth0-u ntop startup service

Command line
In fact, NTOP can also be used through the command line method. Generally, this is the case for experts, because the modification and addition settings under the command line are very fast, and there are still many operations that cannot be implemented through graphics, it is particularly suitable for remote operations.
Common parameters are as follows.
--D: run the command in the background.
--L: write the output information to the system record file.
--R: set the automatic update frequency of the page. the default value is every 3 seconds.
--W: use other ports (default value: 3000 ).
--W: same as-w, but this is online using SSL.
--U: specify other identities for execution.
--I: specify the NTOP listening network card. "," separates multiple network cards.
--M: when you use-I to specify multiple NICs, the default value is merge statistics. to separate statistics, add this parameter.
--H: Get help information.
