Scanning

Scanning

The Scans tab has four sub-tabs: Run · Schedules · History · Changes.

Run — the nmap builder

Build a scan from options, with a live command preview that mirrors exactly what runs.

• Target — the subnet to scan.
• Profile — a saved set of options (see below). Picking one fills in the fields.
• Ports:
  • None — discovery only (-sn): who's online, no port scan. Fast.
  • Top 1000 — nmap's default 1000 most common ports.
  • Top N — the N most common ports.
  • All — all 65,535 (-p-). Thorough, slow.
  • Custom — a range like 22,80,443,8000-8100.
• Options:
  • Service + version (-sV) — identify what's running on each open port.
  • OS detection (-O) — guess the operating system.
  • Skip discovery (-Pn) — treat hosts as up without pinging first (for hosts that block ping).
  • UDP (-sU) — also scan UDP (slower).
  • Timing (T0–T5) — T0 = slow/stealthy, T3 = normal, T4 = aggressive (default), T5 = fastest.
  • NSE scripts — nmap script names, e.g. http-title,ssl-cert.

Click ▶ Run scan.

Scan profiles

Profiles are reusable option sets, used by manual scans, per-host probes, and scheduled scans. Built-ins:

Profile	What it does
Quick	Discovery only (-sn) — populates the host list fast
Standard	Top-1000 ports + version + OS — a solid default
Full	All ports + version + OS

Tune the builder to your liking and ＋ Save as profile to create your own (e.g. "UDP + SNMP", "top-200 fast"). Built-ins can't be edited/deleted; your custom ones can.

History

Every run is listed with:

• Live progress while running (discovering → scanning %, elapsed timer).
• Duration and timestamp when done.
• Skipped runs with the reason (e.g. a scheduled run skipped because the subnet was already being scanned).
• A ⏱ badge with the schedule name for scheduled runs.

Select rows to delete old runs in bulk.

Probing a single host

From a host's detail panel, ⟳ Probe re-scans just that host with a chosen profile — handy to refresh open ports or pick up a newly-found MAC. It shows live in History like a scan.
