NETWORK MONITORING/ INFO GATHERING TOOLS IN LINUX.
1.Why we have to monitor Network ?
Some times we have to monitor Network traffic in our LAN if there is any traffic issues such as “Broadcast Stroms”. Here I am going to explain some Linux tools which are used to monitor network traffic.

I used to struggle a a lot initially to use these tools.

Network monitoring tools can be divided in to three types :

  1. Traffic monitoring tools(which will do just monitoring traffic in network) .
  2. Network monitoring tools(these tools will do just monitoring such as services and devices).
  3. Network Info gathering tools(these tools will just get you info about your network, tools such as ifconfig, traceroute will come under this).

Some of the tools which we are going to cover in it are:-

1.nmap
2.NGIOS
3.echoping
4.smokeping
5.iptraf
6.MRTG(Multi Router Traffic Grapher)
7.rrdtool
8.ntop
9.mii-tool
10.mii-diag
11.tcpdump
12.mtr

I will give the explanation regarding above mentioned tools in my next posts.
