Here is the relevant bit of my configuration: “` $ ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 50:eb:71:37:61:76 brd ff:ff:ff:ff:ff:ff inet 192.168.1.86/24 brd 192.168.1.255 scope global noprefixroute wlo1 valid_lft forever preferred_lft forever … 8: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 100 link/none inet 10.0.1.13/24 brd 10.0.97.255 scope global tun0 valid_lft forever preferred_lft forever “` I would like to run arp-scan on the 10.0.1.13/24 range. “` $ sudo arp-scan -v 10.0.1.0/24 [sudo] password for jonathan: ERROR: Could not obtain MAC address for interface tun0 “` If I spin up a VM and use bridge networking, the 10.0.1.13/24 network shows up as eth0 and I can run arp-scan without a problem. My question is, how can I run it on my host OS? Author Posts You must be logged in to reply to this topic.
