Content delivery is another big one.

#

Netflix installs their own equipment in the datacenter of an ISP

thick minnow
#

Not literal high quality I meant high production value

lean pebble
#

It is when you rent it

tame carbon
#

to optimize delivery to every viewer

lean pebble
#

Ya

#

That's a pain in the ass to

tame carbon
#

@thick minnow and you are from.. america?

#

Because if you are: I can already say: its not gonna happen

thick minnow
#

yep I’m a proud patriot

tame carbon
#

without net neutrality you wont be able to do anything.

peak cloak
#

I mean you will

#

I think you just overestimate what you are getting into

autumn ether
#

I'm pretty sure they do. There's even a toggle on each proxieable record whether you wanna proxy it or just use CF as dns.

peak cloak
#

I used cloudflare before

autumn ether
#

aah

peak cloak
lean pebble
#

Long time ago before spectrum was released you could proxy minecraft servers behind cf with srv not now

thick minnow
#

The idea I had in mind was for it to get big enough so a big company sees it or it gets to point where I can’t handle it anymore than a big company buys it

autumn ether
#

why would you want to proxy game servers anyway, wouldn't that introduce lag? I understand http proxy-ing/cache, but game servers?

tame carbon
#

chest has 27k string

lean pebble
#

Gosh

dusty osprey
#

wth pams harvest craft

tame carbon
#

@dusty osprey yessir

dusty osprey
#

n o s t a l g i a

#

havent touched those since '16

autumn ether
#

would it actually introduce lag tho, or would that be negligeble?

tame carbon
#

@autumn ether minecraft community is toxic. So people with DDoS tools are also around

lean pebble
#

It reduces it but not as much as you think

tame carbon
#

@autumn ether if you run a public server, you really want to have some form of protection against that

lean pebble
#

Depends if you had a close cloudflare hope near you

tame carbon
#

Worst I had

#

was a 22gbit/s attack

#

in 2017

lean pebble
#

My css server had 45gbit attack

dusty osprey
#

MC servers get ddos'ed a lot yes but then my MC server never got ddos'ed 😂

tame carbon
#

@dusty osprey it depends on the audience

lean pebble
#

From the stupid "gaming communities" here

autumn ether
tame carbon
#

@dusty osprey we had a guy trying to get on our development team, to steal our sourcecode.

tame carbon
#

@dusty osprey I traced his name to some public listing for a server, connected to his own server. They had stolen our map.

autumn ether
#

Oooooh lmao 🤦‍♂️ not old enough xD

lean pebble
#

Lol

tame carbon
#

So they were now trying to get our plugin sourcecode

#

I banned the guy, and then he ddosed us

dusty osprey
#

ah, need to mention my server was a graveyard xD its not public

tame carbon
#

@dusty osprey we have 45k registered members :3

dusty osprey
#

well that makes sense :p

tame carbon
#

so small medium size

thick minnow
#

Well I’m gonna try to make my steaming service so wish me luck

tame carbon
#

in 2016-2017, seeing 100+ people online was normal for us

lean pebble
#

Gl

#

Crystal did you ever played counter strike source?

autumn ether
# thick minnow Well I’m gonna try to make my steaming service so wish me luck

good luck, me and a friend of mine tried getting one up so we could help (and profit off) local companies in during height of covid (like a local bakery streaming baking tutorials) but we both quickly realized just how much live video streaming costs. (pre-recorded streaming is significantly easier tho). it's honestly insane yt and especially twitch manage to stay profitable

tame carbon
#

nah

lean pebble
#

I had one of the biggest bhop servers in Israel in counter strike source that's why the other here ddossed it

tame carbon
#

the area around my house is so beautiful

lean pebble
#

They thought that I will join them after they ddossed us

tame carbon
#

butterflies :D

#

there's 100s of them... I'm starting to get worried they will cause lag lmao

lean pebble
#

Lol

#

In one place?

#

100+ in this spot ?

lean pebble
#

There is a real domain that end in gg?

thorny vector
cedar igloo
#

any vsphere/ubuntu experts out there who can point me in the right direction for creating my own custom Ubuntu Cloud images that accept vApp properties (as seen in the image)?

#

the one i am using is published by Ubuntu, but there is some different properties i am wanting to set on first boot too

autumn ether
lean pebble
#

This why I asked because this is the only domain I ever saw with gg ending

peak cloak
thorny vector
#

@cedar igloo Take the cloud image, then you can use cubic to seed it with all the apps you need. No need to try to make a random image gain vapp properties

autumn ether
#

there (used to be?) a guild/forum/socialmedia style website that ended in gg as well, don't remember the name

#
#

apparently they rebranded and now compete with discord lol

peak cloak
#
.gg

.gg is the country code top-level domain for the Bailiwick of Guernsey. The domain is administered by Island Networks, who also administer the .je domain for neighbouring territory Jersey.
In 2003, a Google Search website was made available for Guernsey, which still uses the .gg domain.

autumn ether
#

a bunch of LoL related websites use it as well

#

gog should rebrand as go.gg lol

vale jacinth
#

Guys i need help with my laptop network

autumn ether
#

and it's not even showing the "!". how irrititating. Can you access stuff on your local network at all? Is only the internet the issue?

vale jacinth
autumn ether
#

go to adapter options, what does it say

#

also can you try pinging 1.1.1.1

peak cloak
#

smells like DNS

peak cloak
vale jacinth
#

U mean network settings

peak cloak
#

if not, type ipconfig /all

peak cloak
#

and show the output of ipconfig /all

vale jacinth
peak cloak
#

in cmd

#

windows is useless there

autumn ether
#

you see change adapter options at the bottom? there. and do what monkey says too

peak cloak
#

new windows settings suck

autumn ether
#

change adapter brings up old cpanel dialog

#

or it should/used to at least

vale jacinth
peak cloak
#

ok

#

so dns

vale jacinth
#

What should i do

peak cloak
#

also wdym by you have no internet

#

can you access sites

#

or just certain ones

vale jacinth
peak cloak
#

ok so 99% sure this is DNS

vale jacinth
#

All sites

#

So ?

peak cloak
#

change your DNS server to 1.1.1.1 and/or 8.8.8.8

vale jacinth
#

How

autumn ether
#

in those options I told you about, click on "Change adapter options"

#

should be there

vale jacinth
#

Yea

#

Wi-fi ?

autumn ether
#

can you screenshot? I'm on a Mac, don't remember them by heart

vale jacinth
tame carbon
#

besides ping being very high

autumn ether
vale jacinth
autumn ether
#

double click on the wifi in adapter options. Click on properties. Click on Internet Protocol Version 4. Screenshot what it shows

tame carbon
#

sometimes if a link is congested

#

or a peer with your ISP drops down

#

can happen that you can't access some times

#

do you always have 200ms+ ping?

vale jacinth
#

Sometimes

tame carbon
#

can you ping your gateway

#

and maybe run a traceroute to 1.1.1.1

vale jacinth
#

I dont know how to do these stuff

tame carbon
#

tracert 1.1.1.1

vale jacinth
#

In cmd ?

autumn ether
#

yes

tame carbon
#

run that yes

vale jacinth
#

My ip showed up should i screen ?

tame carbon
#

no, ip of your ISPs router is in there

#

not your public IP

vale jacinth
#

U wanna a screenshot ?

tame carbon
#

yes

autumn ether
vale jacinth
tame carbon
#

@vale jacinth yeah

#

in there

#

just click on "Use the follow DNS Servers"

#

@autumn ether his route to 1.1.1.1 is terrible

#

it uses amsterdam as endpoint

#

even though that's halfway across the globe

#

@vale jacinth check your ping to 8.8.8.8 (google dns) and also compare that to 208.67.222.222 (open DNS)

vale jacinth
#

60-80ms

#

8.8.8.8

tame carbon
#

ok, that's better than cloudflare (1.1.1.1)

#

and what about openDNS

vale jacinth
#

190ms and timed out once

tame carbon
#

ew

#

@vale jacinth alright, so to use google dns, in that sceenshot you sent, click on "Use the following DNS servers"

#

and enter

vale jacinth
#

8.8.8.8 is my only option

tame carbon
#

8.8.8.8
and on the secondary server:
8.8.4.4

vale jacinth
#

Still no internet

peak cloak
#

I mean, you have internet just websites aren't loading

vale jacinth
#

Yea

peak cloak
#

idk what else could be the issue

tame carbon
#

@vale jacinth can you load google?

vale jacinth
#

No

tame carbon
#

that's strange

#

if you can reach their DNS

peak cloak
#
tame carbon
#

you can also reach their webserver

peak cloak
#

does that load

tame carbon
#

I mean, it loads google for me, but only after I accept the certificate error

vale jacinth
tame carbon
#

ur browser is fucked

peak cloak
#

try a different browser?

#

what are you using rn?

vale jacinth
#

Well i tried 3 browsers

#

Chrome

#

Fire fox

#

Opera

lean pebble
#

Smells like ISP problem

peak cloak
#

@tame carbon I wish I could use curl in this situation

tame carbon
#

@peak cloak KEKW

peak cloak
#

what's the windows alternative

tame carbon
#

idk

lean pebble
#

Wget in powrshell

#

I think

#

😆

vale jacinth
#

So should i format my laptop ?

peak cloak
#

wtf, no

lean pebble
#

Talk to your ISP

#

I guess they have a problem in one of their routers

peak cloak
#

@vale jacinth do other devices work?

vale jacinth
#

Yes

peak cloak
#

so not ISP

tame carbon
#

@peak cloak windows network stack blew up?

lean pebble
#

Reboot your pc

peak cloak
#

ok, did you restart windows

vale jacinth
#

Well how i talk to u now if it dont

peak cloak
#

mobile data

tame carbon
#

^

#

imagine not having internet at all

peak cloak
#

windows tech support question #1, did you restart

tame carbon
#

fuck me, that would be so boring

vale jacinth
#

I will try

lean pebble
vale jacinth
#

😔

lean pebble
#

No servers

#

No high latency

#

Without internet is better

vale jacinth
#

Well still same problem

#

I guess im gonna format it

hollow marlin
#

Can you screen shot and share your ipconfig /all before just wiping your PC

peak cloak
#

^

#

@vale jacinth

vale jacinth
#

Thx for help guys

vale jacinth
little schooner
#

@waxen scroll I don't like it when vendor support says they want to setup a remote session meeting to troubleshoot an issue and then say they can't help me. I have two different appliances linked, and as soon as we left the first appliance GUI, he said I need to get the other team involved.

What a waste of time. An email and support asking for screenshots is just as efficient. I can even send them a video file but they insist remote access and live call for even basic questions that an email can solve.

hollow marlin
thorny vector
#

I went to a vendor meet the other day too, actually. They were talking some maaaaad bs about machine learning

#

@little schooner Did they bring an engineer? I've found if a sales team shows up without a backend guy, its a waste of time.

little schooner
#

They didn't but yeah I agree with you @thorny vector

#

Need to throw them those tough technical questions

waxen scroll
#

@hollow marlin hes so impatent

#

i get paid for letting the vendor do this or that

#

its also a break from working

thorny vector
#

The sales team that came to us said that their ai could get 97% confidence with just 200 samples

#

😂

waxen scroll
#

you know how to get an ai with 99% in only a few samples?

thorny vector
#

Overfit?

waxen scroll
#

if i tell you be careful not to tell your bosses

#

You ever see these huge companies going AI this and AI that? Let's see.... TATA Consulting, KPMG, HPe, Cognizant, Verizon, ATT... I could go on

#

you know how they achieve that?

#

The AI is a human in Bangalore

#

paid peanuts but way more accurate than a computer AI

#

however some companies be like I want to replace out highly skilled american employees with AIs

#

it doesnt work when you need thinking done

#

if you need to identify a stop sign, OK

#

a highly complex network? well......

#

@clear igloo monkaS

thorny vector
#

Can’t bring outsourced humans into a SCIF.

waxen scroll
#

right you dont

#

you contract the company and the contractors work at that company instead of yours

thorny vector
#

I’d like to see a human keep up with packet flow while doing full content analysis

autumn ether
#

assembly line of 60 people in Bangalore, everyone gets a second of packets with 1 minute to analyze it weSmart

thorny vector
#

Lol, I’d pay to see that. Especially since usually we’re looking for novel stuff

#

Or bits of machine code sprinkled throughout.

autumn ether
#

scale horizontally, more people with smaller timeshares of packets

#

lag would be 60,000ms tho, cuz you need to give the people a minute to analyze the packets 🤣

thorny vector
#

Wouldn’t work either. Sometimes what’s needed is a bigger picture of what’s going on. Once caught a DNS exfil that was using base64 requests spread out over semi-random periods of time

autumn ether
#

DNS exfil
can you elaborate, what is that. quick rough googling shows something about hostnames, but those are exposed when confirming mail anyway

thorny vector
#

Using DNS requests, sneaking out data by putting it in the requests.

autumn ether
#

How does that even work, DNS is separate server from the host it points to I am just too used to Cloudflare

thorny vector
#

By pointing to the right dns server, that just happens to be compromised. Or by having a listener somewhere else that doesn’t care about any reply.

waxen scroll
#

thats how facebook and twitter work

#

they have 4 seconds to determine if content is racist

#

then they move on

#

thats great AI

#

very fast.

thorny vector
#

Doing it live is a nightmare. Usually what happens is we catch it on the backend from network metadata, then go look at stored pcaps

autumn ether
#

Question - when hosting a website is there any point to running your own BIND DNS config on your own machine? I just disable it for my websites and use Cloudflare.

waxen scroll
#

running your own DNS opens you up as a ddos target

thorny vector
#

Faster control over DNS records, for sure knowledge of what those DNS records are.

tame carbon
#

I doubt your service provider will allow you to host a dns server on port 53

#

its frowned upon

thorny vector
#

Surprisingly Xfinity does.

autumn ether
#

No, I'm talking about a site on a VPS

#

Not from my home

tame carbon
#

illconfigured dns servers can be used to amplify DoS attacks

waxen scroll
#

my company hosts DNS but they use a 3rd party to hide their servers and cache it

autumn ether
#

Like Virtualmin/Webmin comes with a dns server, but I don't really use it for my websites, was wondering if that was a good idea or not

tame carbon
#

But if you are on a VPN

#

you can use a dns server

thorny vector
#

Local data or no data. I only use VPS’s for blind vpn exits.

autumn ether
#

But until then, a VPS it is

jaunty talon
#

Unless you have a reason for running your own DNS-server(s) I would advice against it!

#

Most who does that, do it because they dont want "big corps" to have their DNS-zones

autumn ether
#

and it's not like I need a local DNS server for email to work?

jaunty talon
#

nope

peak cloak
#

I technically self-host local dns

autumn ether
#

Aight, I'll completely disable the module then, good to know I was on the right track

thorny vector
#

@jaunty talon run a full “business” stack. Mainly did it to mirror what some of our customers have, also to self host everything. Not going to lie though, if my mail server went down, I would not rebuild that hellspawn

peak cloak
#

You need rDNS for email?

autumn ether
peak cloak
#

no

autumn ether
#

well pihole still counts 😾

peak cloak
#

most routers have a local DNS server

#

but a router technically is just a router

#

it routes between subnets

jaunty talon
#

@autumn ether dns-server as in hosting zones is one thing and resolver is one thing

peak cloak
#

oh as a nameserver

#

yeah no, don't want to self-host that

#

I let HE do that for me

jaunty talon
#

HE is a good solution for hidden-master

waxen scroll
#

akamai > cloudflare

jaunty talon
#

where you have a dns-server running on a VPS but HE takes all the queries

#

akamai also cost 1000x more than CF :P

autumn ether
#

but cloudflare is cool and hip ^^

waxen scroll
#

yep but it just works. doesnt take the net down like CF either

#

i use their anti ddos and DNS solutions

jaunty talon
#

I would say that CF works as good as akamai

peak cloak
#

idk I used to use cloudflare, but eh I want a simple DNS server

thorny vector
#

@jaunty talon just realized who you are. Wanna say I’ve been very impressed by y’all’s use of rust building gpu libraries.

peak cloak
#

that's why I now use HE dns

jaunty talon
#

@thorny vector thanks :)

autumn ether
jaunty talon
#

we put a lot of efforts into opensource

#

@autumn ether you can pay for CF

#

and they're still 1000x cheaper than akamai

thorny vector
#

Haven’t dove into it too much to be honest. Are y’all implementing ROCm and CUDA support?

jaunty talon
#

For sure

waxen scroll
#

@thorny vector you should be more impressed that he spine/leaf'd the user layer

thorny vector
#

I care more about GPU’s for computational work.

jaunty talon
#

and our library is more of rendering out pixels :)

#

as that's part of what we do :D

autumn ether
#

Tbh it's really interested how Nvidia "locked" quite a few industries in with cuda.

thorny vector
#

Wanna just slap it onto a database and let it go brrrrrr. Yeah, but you’re doing novel stuff with rust. And the drawing people in with support with pretty pixels will eventually lead to other implementations

#

That’s what get me excited.

jaunty talon
#

true :)

thorny vector
#

Been trying to figure out a way to get an data indexer I use (Splunk) to use gpu’s for sequential indexing. But so far there’s really only machine learning style data transformation. Useful, but in multi billion data sets, even our best CPU’s start slogging.

autumn ether
waxen scroll
#

yes, with a NAT

#

but that means you cant have port 80/443 with your main domain if thats a separate server (no virtual host)

autumn ether
#

it's all on the same VPS

thorny vector
#

You’d be better off with a reverse proxy and url rewriting.

jaunty talon
#

indeed, just have nginx do the job for you

autumn ether
#

so if I set up LEMP it'd be something like

server_name admin.lavrenov.io;
location  / {
  proxy_pass         https://lavrenov:10000;
  proxy_redirect     off;

}

?

jaunty talon
#

indeed

#

is 10000 ssl tho?

autumn ether
#

given the :10000 port is an administrator panel for the server, is this a good/secure idea to do? it has SSL, and in fact SSL only

jaunty talon
#

or well, make sure that whatever you run on TCP/10000 has SSL

autumn ether
#

so as long as it has SSL I can reverse proxy to my heart's content?

jaunty talon
autumn ether
#

yeah ofc

jaunty talon
#

you might have to do some ssl magic with proxy also

#

to accept the cert

thorny vector
#

Anything can be ssl. The protocol is not tied to any port.

autumn ether
#

imma try to set up a vps with virtualmin and nginx, gonna test

thorny vector
#

Heck, you can do ssl on port 80 if you really want to flub some people up.

autumn ether
#

but looking at the configuration that does look damn easier to understand than apache

#

if you have SSL configured, is actually closing port 80 a good idea? if your website always redirects to https:// (443) anyway, is there a point to even using port 80?

thorny vector
#

No, it will mess hardcore with anything that defaults https to 443 and http to 80

autumn ether
#

hmm kk

thorny vector
#

You need 80 open for the redirect if it defaults to http first.

autumn ether
#

Man, redhat really fucked everyone over. All the VPS providers have pre-configured virtualmin packages for CentOS, but I dont wanna use them because end of life, so I'm stuck installing and configuring it myself on ubuntu 20.04

#

shakes fist angrily at redhat

thorny vector
#

Or don’t use webmin. It continually has CVE after CVE added for it

#

Web access to system controls is a bad idea.

autumn ether
#

in theory I agree with you, but I dont have the time nor will to spend a few weeks figuring out how to do it all in command line

peak cloak
#

what exactly are you trying to do?

#

website right?

autumn ether
#

I'm trying to achieve hall of fame status on internet.nl with my website (100% on the website test and email test)

#

the website isn't that much of an issue, I got apache done right (tho I'll have to redo it cuz switching to nginx)
but the email... uugh

peak cloak
#

Like to you really need a web panel

#

really isn't hard to do it cli

autumn ether
#

It wont just be a single website, it'll be a lot of different ones later on

#

and that's a lot easier to set up and more importantly manage through a webpanel

thorny vector
#

I think you’d find a lot of people that would disagree on that point.

peak cloak
#

yeah, tbh I find managing my mc server is just easier via cli

autumn ether
#

I'm of the mind that I live in the 21st century, I should make use of dem big screens with lots of colors. I know I'm in the minority within the developer/admin people, but I still like and prefer to use GUIs where I can

#

the server wont have any secure data like credit cards or something running through it, it's just gonna be a host for a portfolio website of me and some friends, alongside some demos of projects, dont much care about security

thorny vector
#

GUIs are great in some situations. The reason the CLI sticks around is because you can parse a lot of information extremely quickly, run things quickly, and query quickly. A GUI adds overhead that adds to time

autumn ether
#

the issue I have with CLI is required time investment to learn it. When you know it it for sure is faster.
But setting up virtualmin took me a couple of hours with a GUI. I'd still be here if I tried setting it all up with a CLI

#

How do you set up ssh key authentication? Like I generate a public and private key.
Which do I upload to the VPS?
How do I use the key instead of username/password?

thorny vector
#

You put the public key inside -home/.ssh/authorized_keys. Then you change the sshd_config to use keys

thorny vector
#

Yes

autumn ether
#

... once I am SSH's into the VPS's terminal, how do I copy local (from my computer) files to it 🤔? Need to upload that certificate somehow

thorny vector
#

Or just paste in the public key. Should only be like 128 chars

peak cloak
#

True

#

That works too

rocky badge
#
mkdir -p ~/.ssh && echo ssh-rsa ... username >> ~/.ssh/authorized_keys && chmod -R go= ~/.ssh
#

That's what I do, I have a Termius snippet to add my public key for hosts that don't have my public key on them lol

autumn ether
#

Woo it works! Thanks guys got it configured

#

I found out you could use ssh-copy-id remote_username@server_ip_address, so I didn't have to create or edit files manually

#

which was nice

plucky berry
#

In terms of Protocols, what is the defined function of TCP? I'm aware it is a reliability protocol to ensure the delivery of packets and to redeliver them if lost, but is IP the actual transmission protocol and TCP & IP work in conjunction with eachother, hence TCP/IP? So when TCP is mentioned as a transmission protocol without IP, IP is entailed aswell?

peak cloak
plucky berry
#

Ah yes the OSI model, I will admit my lecturers in college haven't done the best job at explaining it

little schooner
#

he didnt want students to drop the course

plucky berry
#

IPv6 isint too important as i come to understand as it's not widely implemented no?

little schooner
#

i've seen isp, like comcast, adopt it more but yes, at my work network, its still all ipv4

peak cloak
#

tbh not that complicated

little schooner
#

whats complicated is that there is still gear in use that doesnt have good ipv6 support

peak cloak
#

yep

#

tbh setting up ipv6 on my edgerouter was pretty easy

#

just enable router-advert and specify the prefix

#

and then just give the router interface an ipv6 address

#

so router-advert 2001:470:____:111::/64

#

and then give the router on the LAN side the ip of 2001:470:____:111::1/64

little schooner
#

yeah that sounds very easy

peak cloak
#

and then just some thing like route all ipv6 over tun0

#

and then setting up the tunnel, but HE gave you all the config you needed

#

then I had to do a bunch of troubleshooting why it was so slow, but it was just the routers fault

#

turns out when you have hardware acceleration enabled for NAT ipv6 basically doesn't work, it's like kbps

#

when you turn it off, it's much better

plucky berry
#

I'm assuming a prime reason it hasn't been implemented yet is because IPv4 hasn't reached its limit yet and it's so widely integrated and implemented plus IPv6 addresses (in my opinion) are damn ugly and hard to read.

#

But like overall it is better

peak cloak
#

I mean they are ugly, but I guess it would be better than a bunch of longer numbers

#

what other alternatives are there

#

sadly NAT will always exist

lean pebble
#

Funny I saw in my friend house that his ISP gives both

#

V6 and v4 but whatismyip only shows v4 while the router have ipv6 to and his pc have ipv6 to

little schooner
#

NAT for IPv6

peak cloak
#

ipv6 NAT is stupid

thorny vector
#

Hey, @hollow marlin , when was ipv6 supposed to be fully implemented? lol

hollow marlin
#

20 years ago

thorny vector
#

ipv4 shall REIGN FOREVER!

#

All hail 32 bit networking

peak cloak
#

Urgh

#

I want multiple public ips

#

For now my tunnel is broken because my router can't route ipv6 with HWNAT enabled

DNS poisoning anyone?

#

If it’s gigabit, you’ll be fine.

#

I doubt you’d be able to saturate it’s full switching capability

#

Any switch can only process so many packets at once. So a gigabit switch could only have a couple gigabits of throughput, or upwards of 10,20,etc

#

So say you have a switch with 8 gigabit ports. If you only have 2 gigabits of throughput on a switch, if you tried to fully saturate each port with a gigabit worth of traffic, you’d only be able to get 250mbps on each port.

Yeah.

Ip address is the public IP?

primal ice

service port would be the port you want open on the public IP. Internal port is the port you want to respond on your LAN - IP is the LAN IP of the device you want to respond.

@tame carbon I'm gonna start work on my plex server but I wanna know which Linux distro would you recommend to run on it? (btw sorry for the ping)

primal ice
#

fedora 33 :p

#

any you want. really I'm sure there is a guide tutorial some where to do it.. Mint (whatever version)

tame carbon
#

@thick minnow I recommend any debian distribution

#

Finding help for those online is generally easy

#

Ubuntu comes with sensible defaults, and generally the easiest for anyone getting into linux

#

Ubuntu is based on debian

primal ice
#

so is mint :p

tame carbon
#

Yeah but mint is for a desktop

#

you wouldn't run that on a server

primal ice
#

sure I did for awhile. then ubuntu then fedora server.

thick minnow
#

Thanks guys

tame carbon
#

@primal ice Only reason to run fedora, is the bleeding edge.

#

Fedora is one of those distros that sits ontop of the kernel release cycle

#

updating regularly

lean pebble
#

Hey

#

I love Fedora

#

Fedora as desktop not server

#

Centos for servers

tame carbon
#

@lean pebble CentOS is dead.

radiant shell
lean pebble
#

I'm using centos 7.9

#

Centos 8 is shit

tame carbon
#

@radiant shell CentOS was the first distro I ever used

#

but I'm glad I found debian.

#

system layout and package distribution I just prefer

radiant shell
#

It was the first I used aswell, however I pretty much just use Ubuntu now

tame carbon
#

@radiant shell yah

#

most third party software you might want to install, is often either provided as a generic linux binary

#

or as a debian package

#

more often than not, I have noticed sites giving you either .deb or .tar.gz, but rarely all three with .rpm combined

#

@radiant shell and then ofcourse, there's those people who use snap or flatpak KEKW

#

which defeats the whole purpose of a package manager

lean pebble
#

Lol

#

Discord is little broken in Fedora so I use the binary instead repo

#

I used flatpack for discord than just removed it and back to binary , tar.gz and run it ./discord

#

Then ctl + d

#

The fist distro I used was Debian

#

Then moved to centos and fedora

peak cloak
#

I use snap for discord

#

Just because I don't want to manually update discord

thick minnow
#

I feel like this channel is just a cover for the real channel: The linux channel

tame carbon
#

@thick minnow you're not wrong

#

This is the only place where windows is secondary

#

and most things posted here, assume you run linux :3

heavy vapor
#

can someone help me build a server>

#

?

tame carbon
#

what are your requirements?

heavy vapor
#

well i just recently built my gaming pc

#

im a network engineering student

#

so i wanna get into the field now

#

i graduate in 6 months.

#

so id love to build a server

tame carbon
#

For a home lab?

#

@heavy vapor case is really the only difference

#

and board formats

#

you can buy server cases with a motherboard preinstalled

#

I DIY'd the crap out of that once, buying a random 2U case and putting a mini ITX board inside

#

Professional would be buying a pre-assembled system

#

but that is very expensive

#

you could also buy used servers from ebay, and give them an upgrade

peak cloak
heavy vapor
#

ok

#

and

tame carbon
#

difference between a server and a regular computer, fundamentally

heavy vapor
#

check this out

tame carbon
#

is just the machine being on 24/7

heavy vapor
#

this is my program

tame carbon
#

and running services, instead of clients

heavy vapor
#

im in Vancouver BC Canada based IT student

peak cloak
#

yeah older computers are great for beginner server

heavy vapor
#

with my diploma will i make good money in IT ?

tame carbon
#

@heavy vapor I'm not certified as a network engineer. I came into this from a software development background

heavy vapor
#

nice

tame carbon
#

the need to run servers

heavy vapor
#

so you can teach me powershell xD?

tame carbon
#

for software

#

powershell? nah thats not worth my time

clear igloo
#

Diploma only gets you past the HR bots

tame carbon
#

^ xD

#

true

clear igloo
#

If you can talk to what you've learned then you'll make good money

heavy vapor
#

i don't have money for degree brother

clear igloo
#

well I mean program of any kind

heavy vapor
#

can't i build mini ITX server?

tame carbon
#

idk, to me people who work with computers and can't program, are not as skilled as they could be

heavy vapor
#

so you think i should also learn programming?

tame carbon
#

but that mostly has to do with the level of ignorance of processes and underlying architecture

clear igloo
#

You can build anything and make it a server or you could get a used Dell R620 or something for cheap

tame carbon
#

but this is no criticism for you @heavy vapor

heavy vapor
#

im taking this as constructive criticism

#

xD

tame carbon
#

Cool :D

heavy vapor
#

the more knowledge the better

clear igloo
heavy vapor
#

and in IT its always learning new things

peak cloak
#

I'm just a HS student myself, but tbh getting experience by doing seems a good way to go

tame carbon
#

@heavy vapor I went the budget route. Building a Ryzen system on AM4

#

and Mini ITX is not ideal for a server

heavy vapor
#

hmm i see

tame carbon
#

since you only get a single 16x PCIe slot

heavy vapor
#

oh

tame carbon
#

ideally, you want mATX or FlexATX

heavy vapor

and am i the only one who doesnt use dual monitors

maybe i should lulz

@heavy vapor its just like a regular computer :3

heavy vapor

for my own needs for fun

tame carbon

Servers aren't that much different

heavy vapor

so i can learn with network swtiches etc etc

maybe i should find something on facebook market place like a desktop

and turn it into a server?

tame carbon

@heavy vapor if you need to run windows only software, use a virtual machine on linux kek

thick minnow

Yea or if you have an old pc just lying about, you can use that as well

heavy vapor

i don't have any old pc lyin around

but did you check my program out?

nginx uses like 5mb ram

@heavy vapor yeah thats the usual certification list

heavy vapor

hopefully i chose a good field 😄

tame carbon

CompTIA

and all the other formal certifications

If you want to do routers and switches then something like CML or EVE-NG on a server is great

XD and these are the courses and grades ive gotten so far...

I've had courses on Distributed systems architecture

peak cloak

I myself aren't focusing too much on school, just want to get a degree and work on my own things and internships to build up experience

as well as embedded engineering

Can't wait for Polish School to start back up, that way I can do IT there again

Look for internships, seriously

heavy vapor

and im chillin with 75-80 average.

tame carbon

internships are a great way to get a job

heavy vapor

but those are my grades tho

how tf ima get internship

clear igloo
#

Screw grades, experience and knowledge is key

heavy vapor
#

o

tame carbon
#

Like in programming, if you manage to deliver something of value to the company

heavy vapor
#

but look at my grades they low 😦

clear igloo
#

I've turned down people with certs and degrees out the butt and zero experience because they can't apply it to the questions

tame carbon
#

your knowledge of the system that you worked on, is more valueable to the company

#

than the work you delivered

#

knowledge = money

heavy vapor
#

yes

tame carbon
#

and you build this up with experience

peak cloak
#

yeah, I need to look for senior internships now for next year, if anyone is in the Bergen NJ area and have any advice on companies, that would be great

@heavy vapor here's a pro tip: don't remember the thing itself, just remember where you can find the information on said thing

#

bookmarks to documentation, are more valueable, than memorizing

Knowing how to read documentation is key

there this guy who bullies me in class lowkey cuz he gets 90% and i get 75% average..

wtf? xD

and I bet that person couldn't tell you how to apply something to the real world

is this going in the wall?

it's not outdoor rated though

and sky said its that my pc is soo far away from the router

rare matrix
#

you can run cat5/6 if you get the appropriate cable and its under 100 meters, or you can look into using a pair of MoCA or powerline adapters for existing wiring (coax and power respectively)

#

coax and power are a crap shoot in terms of if what you have in-wall will work for you

k ill have a look on what they are

ty for the helps

rare matrix

np youre on the right track going wired just make sure you get the right solution and stay within spec

i got work now thank you guys for the help ❤️

rare matrix

you only need gigabit link, so you wont need more than cat5e if you do run cable

bronze swift
#

Guys is it hard to run a 100ft Ethernet cable from a room, thru an attic, to my room? (One side of the house to the other side of my house)

#

I have 0 experience in drilling holes and putting Ethernet ports in the wall, but it looks easy on YouTube and I probably should know since I built a pc before

#

But is it really easy to run an Ethernet cable thru walls?

peak cloak
#

If you aren't going over 2 floors it's fine

#

in NA houses that is

bronze swift
#

Yeah NA house

peak cloak
#

for example, basement -> 1st floor is easy, but basement -> 2nd floor is hard

#

so if I had a big attic, it would be easy to do 2nd floor -> attic

bronze swift
#

I have only 2 floors and an attic

#

I’ll try to run the wires first before making Ethernet outlets

#

Oh I need 2 or maybe 3 Ethernet ports on my end, would splitting 1 Ethernet cable into 2-3 ports make the internet speed slower as in 1 cable to 2-3pcs or will the speed be the same as if it was 1 cable to 1pc?

peak cloak
#

also wdym by split

#

using a switch?

#

or pysically the cables like with coax

rare matrix
#

whatever you think you need, run 1.5-2x that

#

if you can, leave a fish string/cable along the drop for future maintenance

ISP offered to run my Cat6 instead of their 5e

between the ONT and my patch panel

eventually I want to do individual runs to each room, instead of using a switch

and patching it later

#

I have fiber to my rack

#

they gave me a desktop ONT for some reason

Ours is outside

#

question, if I have 48 + 24 port switch, I assume a single 24 port patch panel wont do me much good, correct? monkaS

#

fios was just installed on the house opposite of us and they installed an outside ONT so idk

rocky badge
#

Depends

#

not everything has to go through a patch panel

#

I usually just do stuff going outside the rack to a patch panel

#

and stuff within the rack just goes directly into the switch

desert briar
#

I would probs run everything through the patch panel, just to tidy the cabling

#

but then id need a second patch panel pepoJuice

peak cloak
#

I never got a patch panel

rocky badge
#

🥴

peak cloak
#

things go directly to switch

#

eventually I'll get a patch panel

desert briar
#

question is, can you get a 48port 1U patch panel or not?

rocky badge
#

no

#

well yes, but not with normal keystones

desert briar
#

so 24 is all I can get out of 1U

#

punchdown vs keystone patch panel?

#

what should I get eventually

rocky badge
#

keystone

peak cloak
#

easier, right?

#

#

the run from the street is that black wire in the back

Man I really regret buying the 70$ deluxe edition of the game now, every penny counts pepoJuice

#

I was thinking of running a similar setup to:

#

but Id need 3 patch panels for that. And well, that goes from 80$ to 160$ monkaS

rocky badge

desert briar

#
