Usage

``` A open port scanner

Usage: opscan [OPTIONS] [ADDRESSES]...

Arguments: [ADDRESSES]... CIDRs, IPs, or hosts to scan ports

Options: -p, --ports Ports to be scanned e.g. 22,80-443,top100 -t, --timeout Maximum time in milliseconds to scan -c, --concurrency Number of concurrent port scanning -h, --help Print help -V, --version Print version ```

Check if a port is open: opscan scanme.nmap.org -p 80

Scan top-N ports on a domain: opscan scanme.nmap.org -p top100 opscan scanme.nmap.org -p top666 opscan scanme.nmap.org -p top1000

List open ports on localhost: opscan # equal to `opscan 127.0.0.1 -p 1-65535`

Scan specific ports: opscan 192.168.8.5 -p 80,443,3000-6000 opscan 192.168.8.5 -p 1-65535

Scan specific CIDRs: opscan -p 22 192.168.8 opscan -p 22 192.168.8.0/24 opscan -p 22 192.168.8.0/192.168.255.255

Default scan ports and timeouts on private/non-dedicated networks: opscan 127.0.0.1 # ports: 1-65535, timeout: 1000 opscan scanme.nmap.org # ports: top1000, timeout: 3000

Increase concurrency and decrease timeout for faster scans: opscan scanme.nmap.org -t 1500 -c 8000
