USB-C Ethernet + mobile app

Katnet

Put your phone on the network cable. Scan, discover, and fix without opening a laptop.

Katnet combines a compact USB-C to Ethernet adapter with a dedicated app: plug in, attach a cable, and work on the live LAN with subnet scans, Layer 2 and Bonjour-aware discovery, then jump straight into SSH, VNC, or URL checks.

Built for field technicians

When Wi-Fi is wrong, slow, or off-limits, a wire is still the source of truth. Katnet gets you onto that wire from a device you already carry, with an app built for visibility first and action second.

How it works

Three steps from adapter in hand to useful data on screen.

1

Connect hardware

Plug the Katnet USB-C adapter into your phone and connect an Ethernet cable to the network you need to work on.

2

Open the app

Launch Katnet on iOS or Android. Once the wired link is up, the app drives scans and tools on that interface.

3

Scan and respond

Discover hosts and services, including Layer 2 and Bonjour / mDNS context, then open SSH, VNC, or URL tests on what you find.

What the app does

The Katnet device gets you on Ethernet; the app is your toolkit for everything that comes next.

Network scan

Map live hosts and services across the subnet while you are on a real wired path through Katnet.

Layer 2 + Bonjour / mDNS

See nearby devices and friendly names with discovery that respects the LAN you are actually plugged into.

SSH

Open shells on discovered hosts when you need command-line access on the spot.

VNC

Bring up graphical sessions for quick visual verification on compatible targets.

URL test

Check HTTP endpoints and response behavior from the same workflow as your scans.

Why wired from your phone

  • Ethernet when Wi-Fi is not trustworthy or not available
  • One pocket-sized adapter plus the phone you already carry
  • From patch panel to SSH or VNC without unpacking a laptop
