I'm having a problem with ettercap.
Sniff > Unified sniffing > OK
Hosts > Scan for hosts
and I get this in my ettercap GUI:
Listening on eth0... (Ethernet)
eth0 -> 00:23:8B:4C:8E:85 invalid invalid
Privileges dropped to UID 65534 GID 65534...
39 protocol dissectors
53 ports monitored
7587 mac vendor fingerprint
1698 tcp OS fingerprint
2183 known services
Randomizing -1 hosts for scanning...
Scanning the whole netmask for -1 hosts...
0 hosts added to the hosts list...
Two things that I find that are different from the tutorials I'm following is the invalid part and the -1 parts.
Anyone know how I can fix this? Thanks so much!
