Network Scanning menggunakan Nmap [1]

 

 

 

 

 

 

 

Dear all,

Di bawah ini dijelaskan teknik dasar scanning pada nmap (network mapping) buatannya om Fiodor :

Scan a single target —> nmap [target]

Cont : nmap 10.108.12.20

Nmap scan report for 10.108.12.20
Host is up (0.0043s latency).
Not shown: 995 closed ports
PORT STATE SERVICE
135/tcp open msrpc
139/tcp open netbios-ssn
3389/tcp open ms-wbt-server
5800/tcp open vnc-http
5900/tcp open vnc
MAC Address: 6C:62:6D:60:8F:45 (Micro-Star INT’L CO.)

Scan multiple targets —> nmap [target1,target2,etc]

Cont : nmap 10.108.12.20,118

Nmap scan report for 10.108.12.20
Host is up (0.0043s latency).
Not shown: 995 closed ports
PORT STATE SERVICE
135/tcp open msrpc
139/tcp open netbios-ssn
3389/tcp open ms-wbt-server
5800/tcp open vnc-http

5900/tcp open vnc
MAC Address: 6C:62:6D:60:8F:45 (Micro-Star INT’L CO.)

Nmap scan report for acer-ardena.ho.corp.bri.co.id (10.108.12.118)
Host is up (0.0046s latency).
Not shown: 990 closed ports
PORT STATE SERVICE
21/tcp open ftp
80/tcp open http
135/tcp open msrpc
139/tcp open netbios-ssn
443/tcp open https
445/tcp open microsoft-ds

912/tcp open apex-mesh
3306/tcp open mysql
3389/tcp open ms-wbt-server
8081/tcp open blackice-icecap
MAC Address: 6C:62:6D:60:93:42 (Micro-Star INT’L CO.)

Nmap done: 2 IP addresses (2 hosts up) scanned in 1.04 seconds

Scan a list of targets —-> nmap -iL [list.txt] –> simpan address dalam list.txt

Scan a range of hosts —-> nmap [range of IP addresses]  cont : nmap 10.108.12.1-255 

Scan an entire subnet —-> nmap [IP address/cdir] cont : nmap 10.108.12.0/24

Scan random hosts —-> nmap -iR [number]

Excluding targets from a scan —> nmap [targets] –exclude [targets]

Excluding targets using a list —> nmap [targets] –excludefile [list.txt]

Perform an aggressive scan (yg paling lengkap) —> nmap -A [target]

Scan an IPv6 target —> nmap -6 [target]

Bersambung….
