portprober

Bash Script to check if ports are open on some hosts. May also run on other shells (I know of ash and mksh).

Dependencies

ping: (should come with the linux system)
nmap (ncat): needed to check for open ports
figlet: for some fancy output of result
sed/grep/sort/tr

Usage

To run the command with the csv formatted ports file:

$ ./portprober.sh ports.csv

ports list file

The ports list file is a csv formatted file with one IP-Address on each line and separated by "|":

servername|IPv4 or IPv6|comma separated ports list

For example:

scanme.org|45.33.32.156|22,80,9929,31337
scanme.org|2600:3c01::f03c:91ff:fe18:bb2f|22,80,31337
foobucket.xyz|185.232.71.132|80,443,1965
foobucket.xyz|2a03:4000:4e:e28:38ac:4fff:fe98:7018|80,443,1965

You can add as many address lines as you wish. The output is grouped by the servername. It's simply a name, not a FQDN, as portprober only depends on the IPv4 or IPv6 address.

Look at the example ports.csv file
