Happy #WorldPenguinDay! 
Did you know #Tux, the #Linux mascot penguin, was designed by Larry Ewing in 1996 using the #opensource graphics tool #GIMP? The name “Tux” was chosen as an acronym for ‘Torvalds’ UniX’ and a reference to the black-and-white “tuxedo” appearance of penguins.

A question for all the #selfhosting enthusiasts and #sysadmins out there:
I had a Go site on a VPS and recently decided to migrate to self-hosting Ghost on a Digital Ocean VPS (I was using Oracle before) and my site has become basically inaccessible. I checked the RAM usage in my admin and it's consistently above 90%. I have 1GB ram and figured I wouldn't need more since I don't get much traffic, but now everytime I try to open my site it takes forever to load.
What I don't understand is that, on the Oracle VPS, I not only had my Go site, but also had Caddy, Plausible for analytics with a #postgres DB and never had any issues. Now, all I have is the ghost site, mariadb, and caddy and nothing works.
Do I need more RAM or is this a DO thing? Both the Oracle and DO VPSes are hosted in the EU which is pretty far from here, to be fair. I do suspect it's a RAM issue because I can't even ssh into the VPS. When I try to open my site, the connection just loads until it eventually times out.
EDIT: adding the link in case someone wants to check it out, could just be my distance from the server
#Linux #SysAdmins #NetworkAdmins
Ubuntu 24.04 system with a publicly-routable external IP address.
For a given incoming UDP port (<1024, call it port x, I can’t change this), I want to forward that to localhost (or the ens3 interface) on another port (>1024, port y) so I can invoke QEMU as non-root and forward port y to the emulated system’s port x via slirp.
Is this doable?
I’ve tried heaps of nat prerouted examples, but haven’t yet gotten anything to stick.
Boosts appreciated!
@falcennial it's helpful for #sysadmins and anyone who is running their own #firewall (regardpess if WAF, hosted/managed or DIY/bare metal), as they can just pull that Feed-URL to (un)block stuff automatically...
git just to diff&merge stuff because they only offer "add" and "replace" when it.comes to #CSV / #TSV input.
To all #sysadmins 
What #Linux distro's you use in your job currently? 
@sigmasternchen sadly, I've rather seen CxO's rather destroy an entire team of #Linux #Sysadmins by forcing arbitrary bs that *legally isn't "mobbing" instead.
I.e. expecting someone to commute 500+km (!) One-way for no reason but to force said person into a cubicle, as all the systems they administrated weren't onsite!
@Saupreiss das bestreite ich auch nicht!
Wenn alle #Sysadmins ihre "#DueDiligence" bei #Updates gewaltet hätten, wäre all das nie passiert!
IMHO ist ja gerade jene #QA und 24/7 Support der Grund für ne gute Distro zu zahlen...
@Cappyjax @WB2EEE @Zugschlus @elly
I disagree with your assessment to some extent, as on #Linux there's not much of a tolerace or even acceptance of #rootkits like #CorwdStrike for all the right reasons!
Cuz it's not about #Fanboyism, but a fact that most Windows - #Sysadmins (or rather decisionmakers for that matter) seem to be high on #Copium and refuse to take actual #consequences but accept the #Enshittification as a fact of life when it's not...
It's just that this entire shitshow would not have happened on #Linux because here we don't have an entire ecosystem of #ValueRemoving "#AntiVirus" bs being shoved on Desktops and Servers in the form of #Binaryblob #Kernelhacks!
@WB2EEE @Zugschlus @elly Which only applied to a small subset of machines and almost all #Linux #sysadmins know to properly test stuff or at the very least have proper #backups, use #snapshots to test stuff and be able to #backroll stuff if not quickly setup stuff easily.
Further proving my point in that the amount of issues would not have happened on Linux!
I'm happy to be here and after thinking about attending a security test course I decided to focus on creating a #GNU #Linux #Debian #distro which is focused on #security for #sysadmins #developers #pentesters and #artists called #procyberian #ProcyberianSystemsDistribution and then now let's say #happhacking !
https://github.com/procyberian is our home for our projects ! #github
Thanks !
What is the secret to finding cheap/free rack space for a physical server?
so 240,000 people got laid off from #techbro companies so they could go lay down solar panels?
if this is not more reason to unionize all #software #developers, project #managers, info #architects, #sysadmins, whatever the #tech title pops into your mind?
seriously, #unionize Silicon Valley

@evan @peterkaminski @brook @mark @emeraldsocial Evan: "Bayesian filtering..."
That line of thinking brings email servers to mind. My impression is the effort involved to keep one going robustly these days is beyond the reach of even some fairly knowledgeable and dedicated #sysadmins
Maybe what we most need is a metasystem to support learning/evolution of structures which can balance responsibilities of individual, community, and network dynamically over time?
(In a sense, the Internet. ;-)
