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 ```

Scan a single port of a single host: opscan 192.168.8.5 -p 22

Scan all ports of a localhost if no parameters opscan # equal to `opscan 127.0.0.1 -p 1-65535`

Different network types have different default scanning ports: opscan 127.0.0.1 # for private network, scan 1-65535 opscan scanme.nmap.org # for none private network, scan top1000

Scan specific ports: opscan 192.168.8.5 -p 80,443,21-23 opscan 192.168.8.5 -p 1-65535

Scan a whole/range CIDR: opscan 192.168.0.0/24 opscan 192.168.0.0/192.168.255.255

Scan top-N ports: opscan scanme.nmap.org -p top1000 opscan scanme.nmap.org -p top250 opscan scanme.nmap.org -p top100

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