Bypass checking vendor ID in nmap
by mackowiakp from LinuxQuestions.org on (#57QWJ)
I want to check in LAN if the service on specific server is available.
For this purpose I use such command:
Code:root@zegmma-p:~# nmap -Pn -p700 192.168.0.25
Starting Nmap 7.31 ( https://nmap.org ) at 2020-09-04 06:13 CEST
Unable to find nmap-services! Resorting to /etc/services
Cannot find nmap-payloads. UDP payloads are disabled.
Nmap scan report for nanoPI (192.168.0.25)
Cannot find nmap-mac-prefixes: Ethernet vendor correlation will not be performed
Host is up (0.0044s latency).
PORT STATE SERVICE
700/tcp open unknown
MAC Address: 02:81:7D:36:66:BA (Unknown)
Nmap done: 1 IP address (1 host up) scanned in 6.96 secondsAs You can see, there is an error:
Code:Cannot find nmap-mac-prefixes: Ethernet vendor correlation will not be performedIt stops code executing for 2 sec. The command above is executed on IoF Linux based unit. So Debian is rather incomplete. I dont care about info concerning vendor ID so is any way to baybass this checking? I dint find such option in nmap help/man. Any idea?
Is any way to not chech
