Minimal CLI port scanner written in Rust.

Usage

scanr [OPTIONS] <IP> <PORTS>

<ports> accepts a single port, a range, a comma-separated list, or a mix of lists and ranges.

Examples

scan 192.168.0.1 1-65535 --speed thorough
scan 192.168.0.1 22,80,443 --format json
discover 192.168.0.1/24 
discover 192.168.0.1/24 --speed fast

Port input

• 80: scan one port
• 100-1000: scan a port range
• 22,80,443: scan selected ports
• 22,80,100-120: scan selected ports and ranges
• "22, 80, 443": spaces are allowed when the whole port expression is quoted
• "20 - 25": spaces are allowed in ranges when the expression is quoted

Output formats

• table: human-readable output with progress bar
• csv: comma-separated output for scripts or files
• json: JSON-like output for tools

Use --format <FORMAT> to select an output format. The default is table.

Speed modes

• fast: short timeout for quicker scans on LAN
• normal: default timeout, generally good
• thorough: longer timeout for high latency networks or VPN

Use --speed <SPEED> to select a speed preset. The default is normal.

Capabilities

Scanner is able to scan full port range in 3s.

Scanner is also able to discover hosts.
