fipstop

Live-status terminal UI for a running FIPS daemon.

Synopsis

fipstop [-s SOCKET] [--gateway-socket PATH] [-r SECONDS]

Description

fipstop is a ratatui-based dashboard. It opens the daemon control socket, polls a small set of show_* queries on a timer, and renders the state in a tabbed full-screen UI. A separate poll runs against the gateway control socket when the Gateway tab is active.

fipstop is almost entirely read-only: the only state-mutating action it offers is disconnecting a peer (Del on a selected Peers row, with a confirmation prompt — see Keybindings). For connect and other mutating commands, use fipsctl.

Options

Flag	Argument	Default	Description
-s, --socket	PATH	(auto)	Daemon control-socket path / port. Same default as fipsctl.
--gateway-socket	PATH	(auto)	fips-gateway control-socket path / port. Default: /run/fips/gateway.sock (Unix), TCP port 21211 (Windows).
-r, --refresh	SECONDS	2	Poll interval.
-V, --version	—	—	Print short version.
--version	—	—	Print long version.
-h, --help	—	—	Print usage and exit.

Tabs

Tabs cycle in this order. Each tab issues the listed control-socket query on its first activation and on every refresh tick while active.

Tab	Query	Shows
Node	show_status (+ show_listening_sockets)	Identity, version, uptime, peer/link/session counts, sparklines for mesh size, tree depth, peer count, bytes, loss. The Traffic block on this tab is split: TUN counters on the left, the Listening on fips0 panel on the right (see below).
Peers	show_peers (+ show_links, show_transports cross-refs)	Authenticated peers in a table. Selecting a row and pressing Enter opens a detail view.
Transports	show_transports (+ show_links, show_peers cross-refs)	Tree of transport instances with per-link children when expanded.
Sessions	show_sessions	End-to-end FSP sessions.
Tree	show_tree	Spanning-tree state and per-peer coordinates.
Filters	show_bloom	Per-peer Bloom-filter state.
Performance	show_mmp	Link-layer and session-layer MMP metrics.
Routing	show_routing (+ show_cache cross-ref)	Forwarding/discovery counters, pending lookups, retry state.
Graphs	show_stats_history family + show_stats_peers	Stacked time-series plots. Three modes: node-level metrics, one metric across peers, all metrics for one peer.
Gateway	show_gateway and show_mappings against the gateway socket	Pool utilisation and per-mapping state when fips-gateway is running. Empty when the gateway socket is unreachable.

The cycle order in the UI is: Node → Peers → Transports → Sessions → Tree → Filters → Performance → Routing → Graphs → Gateway. The Links and Cache tabs are not in the cycle but are fetched as cross-references to populate Peers, Transports, and Routing detail views.

Listening on fips0 panel (Node tab)

The right half of the Node tab's Traffic block lists local IPv6 listening sockets reachable from fips0, paired with the current inet fips baseline filter classification for each (proto, port). The panel exists to remind the operator which local services are exposed to the mesh and which of those are admitted by the default-deny firewall.

Column	Meaning
Proto	tcp or udp. IPv4 listeners are not enumerated; fips0 is IPv6-only.
Port	Listening port number.
Process	comm(pid) resolved by walking /proc/<pid>/fd/. A trailing * marks wildcard binds (local_addr == ::) — the bind is not fips0-specific, so the operator sees that the service is exposed across every interface, not just the mesh.
State	OPEN (default White) — the baseline filter has a canonical accept rule for this (proto, port). filt (DarkGray) — chain falls through to counter drop. filt? (DarkGray) — a rule references the port but uses matchers (saddr filter, jump, daddr) the panel cannot fully decompose; operator should nft list table inet fips to confirm.

When fips-firewall.service is not active, the inet fips table is absent. The panel renders every row in default White and replaces the title with a yellow banner reading "Listening on fips0 fips-firewall.service inactive — all listeners exposed".

The panel is read-only and unselectable. It refreshes on the same poll tick as the rest of the Node tab. Sockets owned by other users that the daemon could not resolve to a PID render as ? in the Process column; this only happens if the daemon itself is running without root privileges (an unusual dev setup), since walking /proc/<pid>/fd/ for processes the daemon does not own requires elevated capabilities.

The panel is Linux-only; on non-Linux daemons the query returns an empty list and the panel hides.

Keybindings

Press ? at any time for an in-app help overlay. The overlay and the status-bar hint footer both read from a single keybinding registry keyed by (tab, mode), so the always-visible hints describe exactly the keys the current context accepts.

Global

Key	Action
q, Ctrl-C	Quit.
Tab	Next tab.
Shift-Tab	Previous tab.
g	Jump to the Graphs tab.
?	Toggle the help overlay.
Esc	Close an open detail view; otherwise deselect the active table row.

Table tabs (Peers, Sessions, Transports, Gateway)

Key	Action
Up, Down	Move row selection.
Enter	Open detail view for the selected row.
Esc	Deselect the row (return to the tab's overview state).

Peers tab (extra)

Key	Action
Del	Disconnect the selected peer. Opens a Y/N confirmation modal first; this is the only state-mutating action in fipstop.

Transports tab (extra)

Key	Action
Right, Space	Expand the selected transport row to show its links.
Left	Collapse the selected transport row.
e	Expand all transports.
c	Collapse all transports.

Multi-pane scrolling tabs (Tree, Filters, Routing)

Each lays out stacked panes that scroll independently.

Key	Action
f	Move focus to the next pane.
Up, Down	Scroll the focused pane by one row.
PageUp, PageDown	Scroll the focused pane by ten rows.
Home, End	Jump to the top / bottom of the focused pane.

Performance tab (extra)

The Performance tab lays out two panes (Link MMP, Session MMP).

Key	Action
f	Move focus between the Link and Session MMP panes.
Up, Down	Scroll the focused pane.
PageUp, PageDown	Scroll the focused pane by ten rows.
Home, End	Jump to the top / bottom of the focused pane.
s	Cycle the sort column of the focused pane.
Shift-S	Toggle the sort direction of the focused pane.

Graphs tab (extra)

Key	Action
Up, Down	Scroll the stacked plots; in MetricByPeer mode, move the by-peer selection (and follow it when the by-peer detail is open).
Right, Space	Next time window. Cycles 1m / 1s → 10m / 1s → 1h / 1s → 24h / 1m.
Left	Previous time window.
Enter	In MetricByPeer mode, expand the selected peer summary into a full-pane plot.
m	Cycle view mode: Node (stacked node metrics) → MetricByPeer (one per-peer metric across all peers) → PeerByMetric (all per-peer metrics for one peer).
n	Next selector (next per-peer metric in MetricByPeer; next peer in PeerByMetric).
Shift-N	Previous selector.
s	Cycle the sort column of the by-peer summary list.
Shift-S	Toggle the sort direction of the by-peer summary list.

Exit Codes

Code	Meaning
0	Normal quit.
1	Failed to initialise the terminal. The reason is printed to stderr.

A failure to reach the daemon socket is not fatal: the dashboard displays "Disconnected" in the status bar and retries on every refresh tick.

Environment

Variable	Description
XDG_RUNTIME_DIR	Used to derive the default control-socket and gateway-socket paths when /run/fips is absent.

Files

Same control-socket resolution rules as fipsctl. The gateway socket follows the same pattern with gateway.sock in place of control.sock, falling back to /tmp/fips-gateway.sock if neither system path nor XDG_RUNTIME_DIR is available.
