A tiny concurrent TCP port scanner with a tview TUI. No raw sockets,
no SYN scans, just `net.Dial` in a worker pool. About 400 lines, easy
to read in one sitting.
## Build
go build -o portr .
## Use
portr 1.1.1.1
portr scanme.nmap.org -p 1-1024
portr 192.168.1.0/24 -p 22,80,443 --concurrency 256
Run with `--no-tui` for a plain stdout listing you can pipe to other
tools.
## Options
-p, --ports port list or range, e.g. "1-1024" or "22,80,443"
--concurrency worker pool size (default 128)
--timeout per-connect timeout (default 500ms)
--no-tui don't launch the TUI, print results as they arrive
## Why it's archived
- nmap is older than me and works better than this ever did
- rustscan has the same "fast first pass" idea and the extensions
actually matter
- I don't use TUI scanners any more; I use a text file full of
known-good targets
## Alternatives
- nmap
- rustscan
- naabu (from projectdiscovery)
