System

Who reaches this QUniLator, what it runs, and updating it.

Access

The name and password from the first-run dialog — one identity for the web interface, the file shares and ssh. Changing either takes effect on the next request, so the browser will ask again.

Changing the user name also moves the board’s file-share account to the new name. A name is 1 to 32 characters: a lower-case letter or underscore, then lower-case letters, digits, underscores and hyphens.

A board set up another way

If the credentials came from WEBUI_PASSWORD in the environment rather than from this page, the page says so and will not change them — that setting outranks it and is managed outside the interface.

Board

Name is what this QUniLator answers to on the network. Renaming it moves qbone.local, the DNS-SD advertisement, the DHCP lease and the login banner together. Letters, digits and inner hyphens, up to 63 characters.

SSH key installs a public key for the account, which is how you reach a shell and sudo there. Installing one replaces the key already present.

Serial ports

Which of the BeagleBone’s three UARTs carry a Linux login.

ttyS0	the debug header, J1 pins 4/5 — needs a 3.3 V TTL adapter. Also the kernel console.
ttyS1	the cape connector.
ttyS2	the cape connector — and normally held by the external console bridge.

One port always keeps its login: it is the way back onto a card whose network has gone, so switching the last one off is refused. The USB port carries a login of its own as well. A port the emulator is holding cannot take one either — free it by turning the device or the console bridge off first.

The kernel console moves with the login

Turning a login off moves where the kernel prints, and that takes a reboot to settle. Until then the old port keeps printing; the page says so when a reboot is owed.

Console recordings

Sessions captured with Record on the dashboard — both what the machine printed and what was typed at it, whoever typed it. Each can be downloaded or deleted.

Updates

What the installed package is, and what the repository offers.

Check now asks; Show what changed fetches the changelog before you commit. Installing replaces the emulator and restarts the service, so the running machine stops — the page says so before it starts.

An update returns QUniLator to its DIP-selected configuration, so a configuration applied by hand needs re-applying afterwards.

Dismiss stops a version being announced in the sidebar badge; Announce it again undoes that.

Operating system is everything else on the board, the emulator excluded. Packages held back are listed rather than forced — the kernel and the cape support are pinned deliberately. Some upgrades want a reboot, and the page says which.
