Do y’all not reboot after kernel/firmware updates?
part of the reason to use Debian is it doesn’t really need to be updated, at least not very often
It needs to be updated at least several times a year…
depends on your use case
home automation server that doesn’t connect to the internet? nah
media server that only occasionally gets connected to the internet? maybe
anything else that regularly connects to the internet, definitely
home automation server that doesn’t connect to the internet?
Well if uses wireless connectivity with either range broader than your place or is connected to a device that is itself online it can still be a risk. Sure it’s very VERY specific but scanning techniques also improve.
You should install updates regardless
if it’s working and there’s no security risk, why?
(I mean, I actually agree with you, I update even normally airgapped machines because them not being updated feels wrong)
Even if there are no security risks to mitigate, updates can bring bug fixes and, god forbid, new features once in a while.
New features on Debian isn’t something that would make it into the repository. Bug fixes might but only if security relevant.
Software these days will always need security patches
What’s more is that the longer you put off updating the more things will be changed when you do end up updating.
Can I introduce you to OpenBSD where we measure uptime in years?
up… date? what does that mean?
I’ve been running the same AIX kernel since 1993, and my ftp server is still running fine. I don’t know what the rest of these assholes are complaining about.
Prefect response.
I can’t guess exaclty which sarcastic high fantasy themed poster, mug or t-shirt warns others away from which exact kind of action that wastes your time, but I’m confident it is present near your primary work space. (Since tone is hard in text - this assumption is meant to convey a general revernce for you and the various roles you probably fill in your communities!)
Hmm, not my proudest moment.
16:09:15 up 1031 daysPrivate server, though.
Almost 44 days last year before I needed to reboot for an update:
Wait, you guys reboot after an update?
Say what now?
I don’t follow CVEs: when was the last time a remotely exploitable kernel bug was a concern? Ignoring the fact that this is a home server and they likely care about uptime a lot more than exploitation on their LAN.
Generally I expect kernel bugs to be LPEs so updating user space would probably be sufficient for most home servers
The UPS will keep it running long enough to switch to another power source.
I’m guessing OP probably doesn’t have a petrol/diesel generator handy :p
An extension cord running to another room would be enough if the minor electrical work only needs a circuit to be switched off.
That assumes your breakers are labelled well. I turn off like a quarter of the panel just guessing to avoid extra trips.
My UPS just runs on a lead battery. It lasts long enough to run my router and server for a few minutes and cost less than 100€.
I got it when we had electrical issues and using the ironing board would trip the main fuse.
Yeah, I was thinking a UPS wouldn’t hold a load up long enough to do electrical work, but I guess it depends on the nature of what needs to be done
If one is not enough just daisy chain two or three of them.
(Don’t do this)
We had some very large UPSes at work that would be able to keep a server up for hours, but they’re also so heavy it would probably cause the floor in my living room to collapse :p
Having high uptime is not the flex you think it is
You shouldn’t have uptime higher than 60 days
Yeah these days a high uptime is a mark of shame, not a badge of honour.
I tried telling this to my manager for years. He saw it as a “X days since we last had a problem and needed to reboot the server” and took pride in it.
We finally shut it down at over 5 years of uptime. Some docker containers had been running for 4 years straight.
Yes, that means what you think it does concerning update policies. Yes, the server and some containers were exposed to the internet. No, the backups were never tested.
Maybe they’re kexec-ing.
uptime should be handled by the kernel, so a kexec “soft-reboot” would still reset the uptime.
Modular custom single-program kernel running in a VM live migrated across a cluster?
No security revisions over multiple months?
Why, by the way?
If a device hasn’t been rebooted in a long time there is a much higher chance of it not coming back after a reboot. This is made worse by the fact that sometimes power loss is unexpected which means that an outage can occur at a bad time.
The other issue is that a high uptime device doesn’t usually have the latest updates installed. Delaying updates creates security issues and when you do get around to updating it means that more things get changed at once.
The reverse is that if you really know your stuff you can get away with fewer restarts, or even none. But you pretty much have to know every component and update you run while in that untested state.
This is similar to bugs that go away on a restart. If you don’t know why, then you haven’t really fixed it, just rolled the dice again hoping it won’t reoccur.As for updates, on regular systems you can do update everything but the kernel. You do have to restart affected services afterwards (often done automatically).
Even on atomic systems you can switcheroo the subvolume underneath a running system.
Unfortunately the kernel is quite major, so that is a valid reason to see the need to update. Definitely not as pressing as say nginx, sshd, or sudo though. Kernel bugs bubbling up to an exposed attack surface is still quite unusual.
“Shutdown off”
Startup’nt
It’s an alias for “sudo shutdown now”.
sudo poweroff
Ironically, this was one of the primary reasons I have a UPS on everything. The uptime must grow.
Well proxmox is based on Debian so it’s technically included in the original meme
Yes
I just power off the containers. If it causes an issue, it’s so easy and fast to restore from backup, in the long run it saves time versus waiting on clean shutdowns for all 10 or so.
If you don’t have a UPS, just use a suicide cable to energize the circuit while it is disconnected at the breaker.
(/s, if the term suicide cable wasn’t enough of a hint; don’t actually do this)
shutdown off
In English, that’s “shut down”.

🌟🎀 uptime check ✨🌈💖
22:09:13 up 9 days, 12:29, 2 users, load average: 0.03, 0.05, 0.11EDIT: wait why does it say 2 users though 😳
EDIT: wait why does it say 2 users though
Sorry about that, won’t happen again
To make sure all security patches are applied I assume 🧐
Linus Torvalds is just making sure you’re Linuxing correctly
It’s probably your mom.
That’s for your daily driver desktop right? Right??
Regular files check by your FBI agent.
small uninterruptible power supply could be pretty useful
I was vacuuming and accidentally pulled the cord on a 3 month uptime.
My current uptime has survived 2 power outages that lasted about 10 minutes each.
i know the OP was about server, but just curious how long is every one’s uptime on laptop / desktop?
I turn my desktop and laptop of when not in use.
but just curious how long is every one’s uptime on laptop / desktop?
Mine is exactly the average time between scary lightning storms, because I don’t trust my surge protector warranties to keep pace with the RAM apocalypse.
As a professional IT guy, I love to show my users their uptime after they lie to me about how they already rebooted their computer and it still isn’t working right. Yesterday I showed a user her uptime of 152 days which is impressive considering the city she works in has worse average electrical uptime than the state of Texas.
I’ve had a year or two. But kernel updates make reboots. My FreeBSD boxes are much more long-lived than Linux because kernel updates
Anything between 5 minutes and 5 days, including those numbers as well. The more you approach the midpoint between those 2 numbers, the odds of that being near my uptime are lower
Just wear rubber boots and gloves and leave the electricity on
This is the way. For basic residential shit, basic protection and one hand rule is fine.
I use one of these lithium power stations as a UPS for my servers. They are all low wattage so they’ll run on backup for a few hours.

Ups says it has 8 minutes of runtime, chop chop, get going!
