Thirty five and map pings scan and map S.P. target so this scan type lists the host in the specified

2

range that will respond to a ping but allows you to determine which computers are on the line rather

3

than which ports are open.

4

So basically there are four methods in map for Ping scanning.

5

It will send an ICMP echo request packet to the target system and if an ICMP echo reply is received

6

then the system turns on and ICMP packets are not locked if there is no response to the ICMP ping and

7

map attempts to DCP ping to determine whether ICMP is blocked or whether the host is actually online.

8

The CCP ping sends a sin or act packet to any board on the remote system and of course a default is

9

80 if reset or a sin EQ is returned.

10

The remote system won't go online and if the remote system does not respond it is off line or the selected

11

port is filtered and then therefore does not respond to any so when you run an and map pings scan as

12

root the default will be to use the ICMP and ACH methods over this method may not work correctly on

13

all networks especially where ping packets are prohibited.

14

Let me show you an example.

15

So we'll make an active discovery on the network where the virtual computers are that we have established

16

over this.

17

Let's open all of the virtual computers that we have installed open virtual box open.

18

Kelly then extend that zero to two down one five open meadows Floyd ball 10 that zeroed out dude out

19

for but it wouldn't do tend out zeroed out to about seven open windows 7 10 that zeroed out to dot six

20

and then log into Kelly Linux VM.

21

User name root password tour open terminal and write this command and map as P 10 dot 0 2 dot zero slash

22

24.

23

Press enter and the scan results appear and we can see that the computers are open right here

24

in map no ping scanning so if you scan with the end map p n parameter it accepts that the target threads

25

are open scans all the ports for each IP without pinging so it could take a long time to detect master

26

servers especially in large networks use in map pin target.
