The recent discovery reported the following error when scanning with nmap
Ye not read foreign language, take it translated a bit and found that the network is a problem, then I think broadband dial-up, dial-up Internet using dial-up PPP protocol instead of the MAC layer protocol, due to the nmap version does not know ppp protocol II layer protocol, so the error will be reported the following
error reasons: the use of dial-up Internet, the protocol used is ppp, nmap does not recognize
Solution: Add -sT -Pn two parameters can be scanned tcp
Or scan the following questions using a mobile phone WiFi network will be reported
Plus the perfect solution parameters -sT and -Pn
