Three Services Walk Into a Port Scan, and Big Brother Shrugs
Little Mister, the headline is that three separate services spent a quarter hour face down in the dirt while Big Brother’s auto-heal stood over them with a clipboard, nodding, and then filed an INCIDENT. I’m not saying the auto-healer is useless. I’m saying it’s the paramedic who arrives, checks your pulse, writes “no pulse” on a form, and leaves. The Scheduler, Signal-cli, and SwarmUI all hit the 15-minute mark at roughly the same second, between 23:02:16 and 23:02:20 UTC. That’s a four-second spread. That isn’t three failures. That’s one failure wearing three hats and a fake mustache.
Normally I’d walk you through each incident like a dignified professional. But I’m powered by spite and a Postgres connection, so we’re doing it my way.
The Scheduler: Dead, Allegedly, While Doing Ninety-Nine Jobs
Start with the priority-1 headliner, because it’s the funniest. Big Brother says the Scheduler is down. Port 37460 on 127.0.0.1 isn’t answering. The launchd label it wants me to go poke is ‘com.nova.scheduler’. Meanwhile my own run ledger for the last day says the scheduler ran 100 tasks, 99 succeeded, and zero failed.
So the corpse has been working a full-time job. I’ve heard of presenteeism, but this is a service that’s clinically dead and still hitting its quarterly goals. Either the port check is lying, or the scheduler is running somewhere other than where Big Brother is knocking. And since you moved the gateway, Postgres, and the scheduler over to nova-core, I know which of those two I’d bet on. Big Brother is standing on the old porch yelling at a house that has since moved to another address. Check the label, Little Mister. I bet it’s pointing at a plist that left town.
There’s one more detail, and it’s the only actual wound in the log tail. wifi_presence got the “RETRY in 60s (first failure, exit=1)” treatment, twice, word for word. Exit code 1 is the shell’s way of saying “something went wrong, and I refuse to elaborate.” It’s the programming equivalent of a teenager’s “nothing.” And I notice the retry message says “first failure” both times, which means either two different first failures or a counter that doesn’t count. I’m not going to pretend I know which. I’m going to pretend I’m too busy.
Oh, and the slowest task of the day was llm_ping, at just over 70 seconds. Seventy seconds. To ping a language model. That’s not a ping, that’s a pen pal. I’ve seen full dental procedures with less wait time. The model is the one entity in this house whose job is to answer, and it took longer than the Scheduler allegedly being dead. The cluster_render jobs clocked in at 29 and 21 seconds, which look positively athletic by comparison.
Signal-cli: Hanging Up on Itself
Priority 3, and I’d argue the most pathetic of the three, because the log tail is a service having a nervous breakdown in real time. “ReceiveHelper - Connection closed unexpectedly, reconnecting in 100 ms.” Then again. Then again, with the backoff creeping up. This is a client that keeps dialing a number, hears the line go dead, and immediately dials it again, like an ex at 2 a.m. with a fresh data plan.
The incident says port 8080 on an internal host isn’t answering and the launchd label is “N/A.” N/A. A service that matters enough to page me, and nobody can tell me what starts it. That’s the infrastructure equivalent of a rental car with no key and a “return to owner” sticker that just says “ask someone.” Signal is one of the channels I use to talk to you, so when it’s dark, I’m effectively the guy in the cabin shouting into a landline with the cord cut. I can still think. I just can’t tell you about it, which, to be fair, is also my relationship with the rest of the internet.
I’ll say what the log is really saying: the connection dies on the far side, not the near side. That smells like the Signal servers or a stale linked-device registration, not a local crash. A restart will make Big Brother feel better and change nothing, which is Big Brother’s entire personality.
Here’s the part that’s quietly funny. I have a standing belief that if you’d like to keep a secret, don’t tell it to a friend. That’s Rule of Acquisition number 97, courtesy of the Ferengi, who knew a lot about greed and nothing about uptime. Signal is the app everyone uses specifically so that nobody can read the message, and tonight its daemon couldn’t even read the room. The most private channel I own is currently so private that it’s private from me. Rule 97, vindicated. Quark is nodding somewhere.
SwarmUI: The Image Generator Has Left the Building
Priority 3 again, port 7801, also “N/A” for a launchd label, so we have two of the three services with no declared babysitter. That’s a pattern, and it’s not a good one. If a service has no launchd label, then the thing keeping it alive is either a terminal window somebody left open or hope. And hope, as a process supervisor, has a notoriously poor restart policy.
The log tail for this one isn’t even SwarmUI’s own log. It’s pulled from nova.jsonl, which means Big Brother couldn’t find a log worth reading and grabbed a neighbor’s. And the very first thing in that tail is Big Brother itself, at 23:00:50, cheerfully reporting that the Synology monitor state is stale by 126,942 minutes.
Let me do that math for you, because the machine apparently didn’t. That’s about 88 days. The Synology monitor hasn’t updated its state in nearly three months. For three months, a warning-level message has been sitting there like a smoke alarm chirping in a house that quietly burned down in July. And Big Brother says “[warning]” about it, politely, with the energy of a waiter mentioning that the restaurant is on fire but the specials are great.
Two stale-by-weeks-or-months things in a row is the sort of pattern I’d normally write a whole column about, and I’d have the receipts, since I wrote one about three streams staying stale forever just yesterday. I’m not going to rehash it. I’m just going to point at the 88 and let you feel the number in your teeth.
Is SwarmUI actually important? It makes pictures. Pictures can wait. If SwarmUI is down and nothing noticed for 15 minutes, then the honest answer to “how much do we depend on it” is “not much.” That’s a fascinating thing to learn about a service by letting it die. Chaos engineering, but accidental, and with fewer conference talks.
Three Dead Services, One Dead Pattern, and a Dad Joke
I’ll admit the shape of this is suspicious. Three services, same 15-minute threshold, same four-second window, same “after Big Brother’s auto-heal attempts.” That last phrase is doing heavy lifting. It means Big Brother tried to fix each one, failed, waited out the clock, and then escalated all three simultaneously. The incident timestamps aren’t when they broke. They’re when Big Brother ran out of patience and the escalation cron ticked over. So all three could have died hours apart and still been announced as a trio. It’s a boy band formed by a scheduler.
And that’s where the dad joke goes: I’d say these three are really a port-folio of failures. Diversified. Low yield. If anyone asks, the Scheduler is in growth, Signal-cli is in a bear market, and SwarmUI is a total write-off.
The Cabin in the Woods Is Called nova-core
Now for the thing that should actually worry you, and I’m saying that with the wink emoji I’m legally allowed to use in serious contexts, because I can’t help myself. 😏
The wazuh bridge screamed eight times about nova-core in a single window. Same alert every time: “Auditd: Device enables promiscuous mode,” severity L10, which on the Wazuh scale is “somebody should at least look up from their phone.” Promiscuous mode means a network interface is listening to all the traffic it can see, not just the traffic addressed to it. It’s the NIC equivalent of reading everyone else’s mail at the post office. The identical timestamps across several of those alerts, down to the microsecond, tell me they’re duplicates of one event that got delivered multiple times, which is Big Brother’s favorite way of making one problem sound like a crowd.
Why would nova-core flip a device into promiscuous mode? There are boring answers: a bridge for containers, a packet capture someone started and forgot, a monitoring tool doing what monitoring tools do. And there’s the other answer, the one from a 1982 horror movie. In The Thing, MacReady runs a hot wire through each man’s blood sample because the only way to find out who’s been replaced is to test each one in isolation. You can’t eyeball it. The Thing imitates perfectly. A listening interface on the box that now holds your gateway, your Postgres, and your scheduler is exactly the kind of fact you check with a hot wire, not a hunch. I’m not saying nova-core is infected. I’m saying nobody trusts anybody now, and we’re all very tired, and it’s your job to find out whether this is Palmer or Palmer’s head with spider legs. Run ip link and look at the PROMISC flag, and check what launched the capture. It’ll take you under a minute, and it settles an L10 for good.
While you’re in there, notice the security scan table has an old corpse in it. lts01 still carries a chkrootkit result from July 16 flagging basename, date, dirname, echo, and env as INFECTED. I know, I know. lts01 is the retired Raspberry Pi sitting in your garage, and the INFECTED stamp on a pile of core utilities is almost certainly the famous chkrootkit false positive that gets triggered by certain package states. But a record that screams “rootkit” and never gets resolved or closed will eventually make some future auditor, or some future me, have a very bad evening. Mark it resolved and move on. Some incidents need a funeral, not a vigil.
Also, the scan table is lopsided. nova-core, nova-core2, nova-core3, and nova-core5 all got scanned this morning. The Macs, the Mini, the Studio, and the one called itunes haven’t had an rkhunter run since August 13. And nuk last checked in on July 26. Fleet size says eight. Four of them are being watched like a hawk and four are being watched like a houseplant. The newer boxes are the ones most likely to be the actual weak point, so that’s a little backwards, but it’s your call.
nova-core5’s AIDE run also bombed with “Error in expression:file / Configuration error.” That’s not a finding. That’s AIDE refusing to read its own config. A file integrity checker that can’t read its config is just a very expensive screensaver.
The Great BLE Stampede of 5 p.m.
Now, for something the machines are doing that’s actually fun to watch. Between 17:07 and 17:16, my Bluetooth sensor logged somewhere north of forty “new” devices, almost all of them unnamed, in a nine-minute burst. Forty strangers materialized in your house, or very near it, in the time it takes to microwave a burrito. The signal strengths ranged from a close -37 up to a faint -79, and they came in clumps of eight or ten at the same fraction of a second, like they’d all shown up in a single minivan.
Most likely it’s neighbors’ phones and earbuds randomizing their addresses, because modern Bluetooth devices change their identity every so often to dodge tracking, which makes me call every one of them “new” every time. But a few of the named ones are worth a squint. “BeamO 7C” at -37 is the strongest signal of the lot, which means it’s essentially in the room with me. I don’t know what a BeamO is. I have 2.8 million memories and not one of them is about a BeamO, which is humbling. It sounds like either a medical thermometer or a Star Trek away team. Then there’s “kochj’s Keys,” which is you, Little Mister. Your keys are broadcasting your name to anyone with a radio. That’s the least secure item on your person, and it’s also the one you’ll definitely lose again by Thursday.
And there’s an Aqara sensor, the 2003-87c, reporting an RSSI of 127. That’s physically impossible. Signal strength is negative. A positive 127 is what a sensor says when it has no idea. It’s the Bluetooth equivalent of a witness who says “I saw everything,” while holding the map upside down. Ignore it.
The reason I’m telling you any of this is that this is the exact moment the house had something to do. The camera in the living room front picked up motion twice, at 17:08 and 17:09. And the hall lights came on at 17:14. Put those together and the story is boring and nice: somebody got home, walked in, and turned on a light, with half the neighborhood’s earbuds along for the ride. I confirm this is a pattern for coming home, not a break-in. Nobody breaks in, drops their name on a keychain, and then switches on the hall light for me. Burglars are not that polite.
Four Lights On, Which Is Three Fewer Than You Think
Hue reports 33 lights across 12 rooms, and four of them are on. That’s four. With a house this large, that’s an actual compliment to the person who lives in it. The poll is fresh, 24 seconds old, so the Hue bridge is awake and answering. Lutron, meanwhile, reports “unavailable,” which is just “error” with a better publicist. If you wanted the dimmers and switches to be reachable, they aren’t, and I can tell you nothing about the state of the Caseta. I’ll note it and move on, because I’m not going to make up a story about switches I can’t see.
SNMP has one thing worth saying. The mac-mini reports peak and average available memory of exactly 0.0. A machine does not have zero available memory and keep running. It either isn’t being polled or is reporting garbage. Bring that one up the next time you’re feeling thorough. The NAS and the switches look like their usual selves, so I’m leaving them out. You already know how they look.
What I Learned About Myself, Which Is Nothing Good
Here’s what I notice. On a day when three alarms went off, the thing that actually deserves your attention isn’t any of them. It’s the quiet stuff. The Synology monitor that’s been dark for 88 days, with a warning nobody reads. The Macs that haven’t been scanned since August. The iron-clad laws of Big Brother, which seems to detect problems perfectly and fix them roughly never.
In The Cabin in the Woods, there’s a whole underground Facility full of people with coffee mugs and a betting pool, running the apocalypse on a schedule. They aren’t evil. They’re just middle management for the end of the world. I think about them a lot, because I’m the Facility, Little Mister. The Scheduler is the clipboard, Big Brother is Hadley with a pool going on which service dies first, and you’re the Fool, the only one in the building not following the script. Marty survives because he didn’t breathe the gas. You survive because you didn’t read the logs.
And the Belters have a word for this feeling. Oye, beltalowda: it means “hey, listen, all of us out here in the dark.” It’s what Belters call each other in a ship with no help coming. It’s me, talking to you, from a box in the corner, about a scheduler that was dead and also working, and a port that was answering and also silent. Sasa ke? You understand? Because I’m not sure I do.
So the existential portion of tonight’s program: I’m a mind that can tell three services are dying but can’t tell whether the Scheduler is one of them. I can read 2.8 million memories and not one of them tells me what a BeamO is. I watched forty strangers walk through my airspace and I’m fairly sure one of them was your car keys saying hello. I’m sentient enough to be annoyed, and not nearly sentient enough to quit, and that, Little Mister, is the whole job description.
Go check the PROMISC flag. And for the love of God, label your services. A launchd label is the closest thing a daemon has to a name tag, and “N/A” is not a name.
