29 Praktični primjeri NMAP naredbi za Linux sistemske/mrežne administratore
Nmap aka Network Mapper je open source i vrlo svestran alat za Linux sistemske/mrežne administratore. Nmap se koristi za istraživanje mreža, izvođenje sigurnosnog skeniranja, reviziju mreže i pronalaženje otvorenih portova na udaljenoj mašini. Skenira žive hostove, operativne sisteme, filtere paketa i otvorene portove koji rade na udaljenim hostovima.
Pokriti ću većinu korištenja NMAP-a u dva različita dijela, a ovo je prvi dio nmapa koji je ozbiljan. Ovdje u ovoj postavci koristio sam dva servera bez zaštitnog zida da testiram rad Nmap komande.
- 192.168.0.100 – server1.linux-console.net
- 192.168.0.101 – server2.linux-console.net
Upotreba Nmap komande
nmap [Scan Type(s)] [Options] {target specification}Kako instalirati NMAP u Linux
Većina današnjih Linux distribucija kao što su Red Hat, CentOS, Fedoro, Debian i Ubuntu su uključili Nmap u svoja zadana spremišta za upravljanje paketima pod nazivom Yum i APT. Oba alata se koriste za instaliranje i upravljanje softverskim paketima i ažuriranjima. Da instalirate Nmap na specifičnu distribuciju, koristite sljedeću naredbu.
yum install nmap [on Red Hat based systems]
sudo apt-get install nmap [on Debian based systems]Nakon što instalirate najnoviju nmap aplikaciju, možete slijediti primjere instrukcija u ovom članku.
1. Skenirajte sistem sa imenom hosta i IP adresom
Alat Nmap nudi različite metode za skeniranje sistema. U ovom primjeru izvodim skeniranje koristeći ime hosta kao server2.linux-console.net kako bih otkrio sve otvorene portove, usluge i MAC adresu na sistemu.
Skenirajte koristeći Hostname

5. Skenirajte više servera koristeći zadnji oktet IP adrese
Možete izvršiti skeniranje na više IP adresa jednostavnim navođenjem posljednjeg okteta IP adrese. Na primjer, ovdje izvodim skeniranje na IP adresama 192.168.0.101, 192.168.0.102 i 192.168.0.103.

Ako imate više hostova za skeniranje i svi detalji o hostu su zapisani u datoteci, možete direktno zamoliti nmap da pročita tu datoteku i izvrši skeniranje. Hajde da vidimo kako to da uradimo.
Kreirajte tekstualnu datoteku pod nazivom “nmaptest.txt” i definišite sve IP adrese ili ime hosta servera koji želite da skenirate.
[root@server1 ~]# cat > nmaptest.txt

server2.linux-console.net

Nmap finished: 1 IP address (1 host up) scanned in 12.624 seconds24. Skenirajte udaljene hostove koristeći TCP ACK (PA) i TCP Syn (PS)
Ponekad firewall za filtriranje paketa blokira standardne ICMP zahtjeve za ping, u tom slučaju možemo koristiti metode TCP ACK i TCP Syn za skeniranje udaljenih hostova.
