Usage

A open port scanner

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

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

Options:
  -p, --ports <PORTS>              Ports to be scanned e.g. 22,80-443,top100
  -t, --timeout <TIMEOUT>          Maximum time in milliseconds to scan
  -c, --concurrency <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
