~ Bash Port Scanner

Simple bash-native port scanner, because why not.

Usage

delay can be a range (i.e. 5-10)

portscan.sh [-d <delay>] [-r <resolver>] [-t <threads>] [-w <timeout>] [-o show_open] [-f <output_file>] <ports>

Examples

• Scanning common ports of single IP

$ echo 192.168.0.1 | ./portscan.sh

• Scanning domain using custom resolver

$ echo scanme.nmap.org | ./portscan.sh -r 8.8.8.8 -w 5 22,80,443

• Scanning CIDR, 3 IPs per second

$ echo 192.168.0.0/24 | ./portscan.sh -t 3 -d 1 22,443-445,80

• Scanning list of IPs, store open ports in file

$ cat ips.txt | ./portscan.sh -f open.txt -o 22,445
