Thanks a lot, it worked out..

Now, I would like to automate the process via cron;

Here below the last log from the server:

stybloga ftpd20571 ::ffff:80.99.99. Sun Sep 20 08:52 gone - no logout
stybloga ftpd20569 ::ffff:79.117.15 Sun Sep 20 08:52 gone - no logout
stybloga ftpd20568 ::ffff:95.223.19 Sun Sep 20 08:52 still logged in
stybloga ftpd20553 ::ffff:188.27.12 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20552 ::ffff:85.66.149 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20550 ::ffff:84.227.20 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20534 ::ffff:89.102.22 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20518 ::ffff:89.173.62 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20511 ::ffff:94.19.144 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20509 ::ffff:89.103.12 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20508 ::ffff:86.101.22 Sun Sep 20 08:51 gone - no logout
stybloga ftpd20507 ::ffff:80.2.176. Sun Sep 20 08:51 gone - no logout

Where :
stybloga -> is the username
::ffff:80.2.1 -> ip address connected to the users.

What I am doing right now is

1) last | grep stybloga | awk '{print $3}' > one
2) awk -F. '{$0=((!$NF)?$0:$0FS)"0/8"}1' one > ipblck
3) Using the bash script, I will block the ip's
#!/bin/bash
BLOCKDB=/root/ipblck
IPS=$(grep -Ev "^#" $BLOCKDB)
for i in $IPS
do
iptables -A INPUT -s $i -j DROP
iptables -A OUTPUT -d $i -j DROP
done

So, now what I am trying is, there are different user like the same as above using different ip adderss.

1) Need to check the users in the last log, if a user count exceeds more than of 10 times,
2) Then it should check the third value, which is the ip address . If that do differs with different ip address for the 10 counts then
3) then the ip address should be taken and do as like the process what I have mentioned above.. the 3 steps that I am doing now..

I hope it make sense...

Regards
Siva

LEARN ABOUT LINUX

securenets

securenets(4)							   File Formats 						     securenets(4)

NAME

       securenets - configuration file for NIS security

SYNOPSIS

       /var/yp/securenets

DESCRIPTION

       The   /var/yp/securenets  file  defines	the  networks  or hosts which are allowed access to information by the Network Information Service
       ("NIS").

       The format of the file is as follows:

	 o  Lines beginning with the ``#'' character are treated as comments.

	 o  Otherwise, each line contains two fields separated by white space.	The first field is a netmask, the second a network.

	 o  The netmask field may be either 255.255.255.255 (IPv4), ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (IPv6) , or the string ``host''  indi-
	    cating that the second field is a specific host to be allowed access.

       Both  ypserv(1M)  and  ypxfrd(1M)  use the /var/yp/securenets file.  The file is read when the  ypserv(1M) and ypxfrd(1M) daemons begin. If
       /var/yp/securenets is present, ypserv(1M) and ypxfrd(1M) respond only to IP addresses in the range given.  In order for	a  change  in  the
       /var/yp/securenets file to take effect, you must kill and restart any active daemons using ypstop(1M) and ypstart(1M).

       An  important  thing  to note for all the examples below is that the server must be allowed to access itself. You accomplish this either by
       the server being part of a subnet that is allowed to access the server, or by adding an individual entry, as the following:

       hosts 127.0.0.1

EXAMPLES

       Example 1: Access for Individual Entries

       If individual machines are to be give access, the entry could be:

       255.255.255.255	   192.9.1.20
       or

       host 192.0.1.20

       Example 2: Access for a Class C Network

       If access is to be given to an entire class C network, the entry could be:

       255.255.255.0  192.9.1.0

       Example 3: Access for a Class B Network

       The entry for access to a class B network could be:

       255.255.0.0    9.9.0.0

       Example 4: Access for an Invidual IPv6 Address

       Similarly, to allow access for an individual IPv6 address:

       ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff	fec0::111:abba:ace0:fba5e:1
       or

       host  fec0::111:abba:ace0:fba5e:1

       Example 5: Access for all IPv6 Addresses Starting with fe80

       To allow access for all IPv6 addresses starting with fe80:

       ffff::  fe80::

FILES

       /var/yp/securenets      Configuration file for
				NIS security.

       The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP).  The functionality of the two remains the same; only the
       name  has  changed. The name Yellow Pages is a registered trademark in the United Kingdom of British Telecommunications plc, and may not be
