Overview

Issues triggered by running scans, including network load, missing hosts, and scan performance.

Host Discovery

Hosts missing from discovery results — ARP issues, switch rate limiting (DAI), Npcap, and tuning.

Phantom Hosts

Hosts recorded at addresses that hold no device, or missing from addresses that do, on subnets reached through a router.

Scan Performance

Scans crashing targets, taking hours, failing from high concurrency, or hitting file descriptor limits.

Credentials

Credential file read failures, PEM errors, and credentials loading successfully but failing authentication on target devices.
