There are some pots found by "nmap to 10.0.0.5 which is metasploitable2" But there are no ports found by "masscan to 10.0.0.5" Please see attached file and give me advice. 2020-10-30_17h11_41

Seeing the same; what is the output of masscan -v?

You rate is most likely too high. I am running 1.0.6, which I built from master and everything is light and bright. When doing scans unless I have an undying urge I generally limit my rate to 1000. At that point I have a nice mix of performance vs false negatives. I generally run about 2 minutes per host scanning all tcp and udp ports with the default SYN scan.

@mattyjones Slowing rate cannto solve the issue.

I think this can be closed as resolved
