In order to solve this problem, this article introduces the corresponding analysis and answer in detail about how to monitor the ntop of Linux server, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Ntop

Ntop is a traffic monitoring tool similar to sniffer, which displays traffic information in more detail than mrtg.

1. Install some dependent software

[root@localhost bandwidthd] # yum install-y gcc libpcap-devel libpcap libtool automake autoconf gdbm gdbm-devel libevent libevent-devel rrdtool rrdtool-devel zlib zlib-devel

2. Install geoip software, which has multiple dependencies and can be downloaded from https://centos.pkgs.org. Several rpm packages should be installed at the same time

[root@localhost wj] # rpm-ivh GeoIP-1.6.9-2857.el6.art.i686.rpm GeoIP-GeoLite-data-2017.05-1.el6.art.noarch.rpm GeoIP-GeoLite-data-extra-2017.05-1.el6.art.noarch.rpm geoipupdate-2.2.2-2.el6.art.i686.rpm

1:GeoIP-GeoLite-data-extr### [25%]

2:GeoIP-GeoLite-data # # [50%]

3:geoipupdate # [75]

4:GeoIP # # [100%]

3. Download the ntop software (https://sourceforge.net/projects/ntop/files/ntop/ntop-4.0.1/ntop-4.0.1.tar.gz/download)

4. Decompress bandwidthd.

[root@localhost ~] # tar-xzvf ntop-4.0.1.tar.gz

5. Installation. Ntop needs to be compiled and installed, first execute the autogen.sh file, generate makefile, and then compile and install

[root@localhost ntop-4.0.1] #. / autogen.sh

[root@localhost ntop-4.0.1] # make

[root@localhost ntop-4.0.1] # make install

6. Configure firewall and increase port 3000 of tcp.

[root@localhost GeoIP-1.4.8] # gedit / etc/sysconfig/iptables

-An INPUT-m state-- state NEW-m tcp-p tcp-- dport 3000-j ACCEPT

[root@localhost GeoIP-1.4.8] # service iptables restart

Iptables: set chain to policy ACCEPT:filter nat [OK]

Iptables: clear firewall rules: [OK]

Iptables: uninstalling module: [OK]

Iptables: apply firewall rules: [OK]

Iptables: load additional modules: nf_conntrack_ftp [OK]

7. Start ntop

[root@localhost GeoIP-1.4.8] # / usr/local/bin/ntop-d-L-u root-P / usr/local/var/ntop-- skip-version-check-- use-syslog=daemon

8. Type "127.0.0.1 3000" in the browser to open the ntop.
