"nom" des appareils distants

#1Messageil y a 1 mois

bonjour à tou.te.s

peut_on retrouver le "nom" des appareils connectés
au réseau local (freebox pour ne pas le citer ) ?

avec nmap -T5 -sP --system-dns 192.168.1.0/24 | grep report | grep -v gateway
on affiche

		Nmap scan report for 192.168.1.19
		Nmap scan report for 192.168.1.34
		Nmap scan report for lenovo (192.168.1.49)
lenovo c'est le "nom" du pc local
mais ceux distants ?

avec arp -a | grep -v _gateway
on affiche

		? (192.168.1.19) at e4:9e:12:5c:02:1e [ether] on wlp1s0
		? (192.168.1.34) at 28:e3:47:b9:07:04 [ether] on wlp1s0
aucun "nom"

y'a un truc qui donnerait cela ?
avec l'IP ou l'adresse mac ( ou autres ? ) ou pas

merci d'avance

Bonjour.
J'ai essayé avec nmap en pointant ma box et j'ai ceci:

du à la version ( 7.80 pour moi ) ? à la compilation depuis les sources ?
à ma config ? à une bétise de ma part ?
