I'm a week into my new job right now. What do I love the most about it?
Learning things all day long and getting paid for it!
I'm learning about hosting things, DNS, cyber security, configurations, Linux (although my current skill set with Linux has been enough for now) and so on!
Hell, easy day today (not that many tickets) so decided to start learning Ansible! Next to that I've gotta learn vim (it just autocorrected that to cum.... O.o), work with hosting panels, mail stuffs (dns, debugging etc etc) and so fucking on.
The boss hasn't been at location yet which will happen tomorrow but he seemed like a very chill guy.
I love this!21 -
Dear namecheap, I honestly love your service and prices but how in the hell can I see an ip address in the dig of a new domain (url shortener) which I never put or saw there and which doesn't even belong to any server I own/operate?!
DNS cache after the last chance of three days ago, nah, don't think so.
Fucking hell.6 -
Routing and analysis of http behaviour with wireshark makes so much joy and fun.
Wanna get even more fun?
Add DNS. Add loadbalancers.
Loadbalancers?
Hell Yeah!
VLAN X has it's own router and domain overrides to give a service a seperate IP pointing to a loadbalancer inside the VLAN X.
loadbalancer in VLAN X then has additional routes to point to loadbalancer in VLAN Y.
Which might then point to the service in VLAN Y or... point to another loadbalancer in VLAN Z.
I'm always amazed what a human mind can create....
If you think that's insane, then add HTTP keepalive and persistent connections.
I just love people who have no idea what they're doing but are able to create a clusterfuck of brainfuck....

Either CloudFlare itself has decided to join the fun of attacking my DNS server, or somebody is just spoofing their IP in the UDP packets.
Crap, my ipset script is basically useless now, since the real source could be from anywhere :(
Any suggestions on what could I do to make this attack stop? It's not causing any real issues (at least for now), but it's still annoying as hell.
Get fucked, stupid skiddie who keeps manually changing the ip source in his script

I already wrote a rant about this yesterday, but since I'm a sysadmin trying to convert to dev.. I dunno, maybe it's not a bad idea to muddy the waters a bit and talk about why not to be a sysadmin.
Personally I think it's that the perceived barrier to entry is just too high, while it isn't. You don't need a huge Ceph cluster and massive servers when you're just starting out. Why overbuild an appliance like that if it's gonna start out at maybe 5 requests a minute?
Let's take an example - DNS servers! So there's been this guy on the bind-users mailing list asking how to set up a DNS server on 2 public servers, along with a website. Nothing special I guess - you can read the thread here: https://0x0.st/ZY-d. Aside from the question being quite confusing, there was advice to read RFC's, get a book, read the BIND ARM, etc etc. And the person to deny this? No one less than Stephane Bortzmeyer, one of the people who works for nic.fr (so he maintains the .fr TLD) and wrote some of those RFC's as part of the DNSOP working group in the IETF. As for valid reasons to set up a DNS server? Could just be to learn how the DNS works, or hell even for fun. As far as professional DNS servers go.. this (https://0x0.st/ZYo9) is the nugget that powers the K root server, one of the 13 root servers that power the root zone of the internet, aka the zone apex. 2 RJ45 connections, and a console connection. The reason why this is possible is the massive recursor networks that ISP's, Google DNS, Cloudflare DNS, Quad9, etc etc provide. Point is, you don't need huge infrastructure to run a server!
Or maybe your business needs email. How many thousands of emails per second are you gonna need to build your mail server against? How many millions will you need to store? If your business has 10 employees and all of those manage about 10k emails total.. well that's easy, 100k emails total. Per second? Hundreds of emails per second per employee? Haha, of course not. Maybe you'll see an email a minute at most. That is not to say that all email services are like this - it is true that ISP's who offer email to their customers, and especially providers like Microsoft and Google do need massive mail servers that can handle thousands of emails per second. But you are not Microsoft or Google. So yeah, focus on the parts of email that are actually hard.. and there is plenty.
Among sysadmins you have this distinction between "professional" sysadmins and homelabbers. I don't mind the distinction itself but I think both augment each other. If you've started out by jumping into a heap of legacy at an established company, you will have plenty of resources, immediately high complexity, and probably a clusterfuck right away. But you will have massive amounts of resources. If you start out with a homelab, you will have not many resources, small workloads, and something completely new for you to build and learn with. And when running a server like that, you'll probably find that the resources required are quite small, to provide you with your new services. My DHCP servers take 12MB memory each. My DNS servers hover around the 40MB mark. The mail server.. to be fair that one consumes around 150. But if you'd hear the people saying that you need huge servers.. omg you need at least a TB of RAM on your server and 72 cores, massive disks and Ceph!1!
No you don't. All that does is scaring people away and creating a toxic environment for everyone. Stop it.1 -
GOOGLE, I WANT TO FUCK YOUR ASS, WHY THE HELL THE NEWER VERSIONS OF ANDROID ARE NO LONGER ABLE TO OPEN THE FUCKING WEB APPS ON LOCAL NETWORKS, THE SAME APP IS ACCESSIBLE FROM IOS AND FUCKING ANDROID CAN’T FIGURE OUT THE CORRECT DNS OF THE LOCAL IP ADDRESS BECAUSE YOU DROPPED IPV4 SUPPORT YOU ASSHOLES.6

I just wanted to transfer my domain from domain operator dns to other dns provider.
Now I lost control over my domain and it redirects to those fuckers website.
I thought fuck them, this is their last fuck up so decided to transfer domains from this piece of shit provider to any other.
It turned out you need to send request using post office or visit their office by yourself to get EEC (authinfo) code
Their office is 300km away but cause it’s fucking faster and more reliable then waiting a month for their mail with fucking numbers I will go and do it next week.
Let the fucking hell begin.
I hope those motherfuckers would food poison and shit themselves into their beds till end of their fucking life.
Fuck those fuckers.6 -
I think I finally, really, comprehend why secret societies have historically been created... I mean the potentially logical ones. This train of thought is logically terrifying.
I want a logic check.
I've been jokingly mentioning some of my totally true, practically useless in most scenarios, skills/specific fields of knowledge/ability under a moniker of 'extremely useful, assuming apocalyptic event' for years. Things like advanced knowledge of Coefficients of glass expansion, Fortran, various things that have caused friends to refer to me as MacGyver after the reboot came out.
In recent years, I've personally encountered several varieties of the ones defined by helplessness, self-victimisation, some version of a real disability... that theyve expounded into a personified personal nemesis-- to flashily battle yet never overcome, etc... the vast majority perplexing me as to why that's a valid form of life to them... it's not that they never consider some other way; the ball is just quickly dropped and never picked back up.
College?(not that I'm a big fan) they wish they could but so expensive... aide? The form was hard/confusing/past-due...
Lookup/learn something more indepth than a tiktok? *some self-deprecating bs*
Yet it's "I always wanted to do/be/learn X"
Shows like 'How It's Made' fascinate, but don't inspire enough for a 5min google query.
In the dev world its a clear, inverted pyramid-- one of the first posts I saw when I rejoined here was ostream's rant on Apple sucking because after they stop support/updates you "can't" load a different OS... ofc you can. But several comments down... no mention of that... i think it was @LensFlare who was the only one in ~15 respondents to point out the core logical fallacy.
Basic shit is totally forgotten... try asking some random adults what plastic is made from... or pay attention to how many people declare they have a gluten "allergy".
I get people frequently telling me that things im pointing out as differences don't matter because "it's just semantics"... semantics is literally the epitome of "significance", with roots in 'meaning' and 'truth'
Back to the main issue... We are in a world where DIY is typically something you pay more to do as a catered experience than actually learning anything, people destroy their own arguments hopes of validity unwittingly often by stating the arguement, get 'offended' or 'triggered' by factual statements, propagate misinformation and bastardise words until MW needs money enough to print a new version, likely adding the misuse as an actual definition and basic knowledge and the thought to actually learn is vetoed by the existence of google translate, the wisdom of tiktok and the pure brillance of troubleshooting every random linux issue you have from not knowing basic CLI and thinking linux makes you cool, with chmod 777 because so many other dumbasses on forums keep propagating misinformation. Ask them what 777 means, most have no clue... as they didnt consider googling that one before putting it in a terminal several times.
The number of humans that actually know the basic shit that the infrastructure of the world is built on keeps decreasing... and we aren't even keeping a running tally.
The structure of the internet has the right idea... dns- 13 active master root servers, with multiple redundancies if they start dropping... hell ICANN is like a secret society but publicly known/obfuscated... the modern internet hasnt had a global meltdown... aside from the lack of censorship and global availability changing the social definition of a valid use of braincells to essentially propagating spam as if it's factual and educational.
So many 'devs' so few understanding what a driver is, much less how to write one... irl network techs that don't know what dhcp is or that their equiptment has logs... professionals in deducated fields like Autism research/coping... no clue why it was called "autism", obesity and malnutrition simultaneously existing in the same humans... it's like we need to prepare a subterranean life-supporting vault and stock it like Noah's ark... just including the basic knowledge of things that used to be common/obvious. I've literally had 2 different, early 20s, female, certified medical assistants taking my medical history legitimately ask if not having a uterus made it harder to get pregnant...i wish i was joking.
Any ideas better than a subterranean human vault system? It's not like we can simply store detailed explanations, guides, media... unless we find a way to make them into obfuscated tiktok videos apparently on nonsense or makeup tutorials.11 -
OK, I've got a couple customers I provide e-mail hosting for, but recently it's been...more trouble than it's worth, to put it simply. I'm looking to offload that part of what I do onto another service.
Does anyone have any recommendations for e-mail hosting services? Bonus points if they have good customer support.3
