Homebrew/Mac

Smap is also avaible on Homebrew.

brew update
brew install smap

Usage

Smap takes the same arguments as Nmap but options other than -p, -h, -o*, -iL are ignored. If you are unfamiliar with Nmap, here’s how to use Smap.

Specifying targets

smap 127.0.0.1 127.0.0.2

You can also use a list of targets, seperated by newlines.

smap -iL targets.txt

Supported formats

1.1.1.1 // IPv4 address
example.com // hostname
178.23.56.0/8 // CIDR

Output

Smap supports 6 output formats which can be used with the -o* as follows

smap example.com -oX output.xml

If you want to print the output to terminal, use hyphen (-) as filename.

Supported formats

oX // nmap’s xml format
oG // nmap’s greppable format
oN // nmap’s default format
oA // output in all 3 formats above at once
oP // IP:PORT pairs seperated by newlines
oS // custom smap format
oJ // json

Note: Since Nmap doesn’t scan/display vulnerabilities and tags, that data is not available in nmap’s formats. Use -oS to view that info.
