What is the issue you are facing

lean pebble
#

Any good pcie extension for sata?

thick minnow
#

rn I have a modem in my basement, and 3 wireless amplifiers from which I can run ethernet. I get about 60-80mbps, though I want to achieve higher speeds. What shall I do? We get 100mbps from our ISP so that sucks.

tall pagoda
#

Call your ISP to raise internet speed to 250 Mbit/s

I run some servers so I want that to be isolated. I only have 1 nic so vlans are nice as I have one for management, 1 for wan servers, and 1 for lan server. When I make a VM I just select the linux bridge I want. Also it's great for testing. So like for example only I want to be on the ipv6 enabled network so I just change the vlan for my PC. Also multiple ssids corresponding to different vlans. Pretty useful as I have one that's 192.168.x.x for work vpns so it doesn't conflict.

#

So my wan server network is completely firewalled off

#

Can't access anything internally

tame carbon
#

@peak cloak same here, my LAN can just access my public range with NAT

#

but I don't masquerade

lean pebble
#

Should I use unraid for my home backup / plex server?

tame carbon
#

and pay for linux? lel

lean pebble
#

I already have it

#

I bought it long time ago

#

Unraid

thick minnow
lean pebble
#

I want to do software raid there is away to do it while installing my Linux os or only after everything installed?

tame carbon
#

I did that post install

#

but only because my root volume isnt on raid

lean pebble
#

Never had a chance to do it via installation

#

Which Linux distro would you guys use for a small VM host? I'm considering moving OPNsense into a VM. Usually I'd go for Arch Linux for the host but it doesn't seem like a great idea to use a rolling release distro as host for an infrastructure critical system

lean pebble
thick minnow
#

Ubuntu server

tame carbon
#

@patent egret I just installed debian and am using kvm

plain siren
#

I use Alpine because I keep everything bare bones and its defacto debloated

lean pebble
#

I'm on fedora but this is me because it's my main os on my main pc

patent egret
#

There might be another VM on the same host for non-critical services that have to be available all the time but no more than 2. Sadly the machine itself is based on an i5-4590 (4 cores, no hyperthreading/SMT)

lean pebble
#

But probably Debian based os

tame carbon
#

debian from a netinstall with minimal packages is already quite bloat-free

patent egret
#

I was considering Xen as well. Gotta look into SmartOS - haven't heard that one before

tame carbon
#

doesnt beat alpine, but its still useable

thick minnow
#

ClearLinuxOS (by Intel) ftw (jk btw)

plain siren
#

Idk, with thier mid-progress of moving Init Systems plus their Tendency to have all the Data Files for every Alt Package avail for every core service for their.... compatibility... it feels pretty bloat

peak cloak
#

idk how heavy proxmox is, but it uses KVM/QEMU which is pretty light weight for VMs

#

you could just do debain + KVM/QEMU

plain siren
#

K3OS + K3S + Containers and be almost paper thin light weight.

#

Skip the Hypervisor all together

tame carbon
#

Debian + kvm/qemu, and virt-manager as frontend

#

virt-manager works with Xen as well

plain siren
#

Portainer hehe

patent egret
#

yeah ofc it does, Xen uses KVM/QEMU too

tame carbon
#

I can't be bothered to learn how to configure libvirt by hand xD

plain siren
#

OpenNebula because itll do it all for you anyways.

tame carbon
#

wat

#

@plain siren what kind of dark magic is that

#

8GB ram

#

3056 virtual machines

#

?

plain siren
#

Its a Demo Pic

#

Its a full blown AWS in your pocket.

tame carbon
#

how does it interface with baremetal?

plain siren
#

from PXE Installing of your Hypervisor down to VM Creation and K8s/Container Clusters Creation Inside those VM's.... itll do it all

tame carbon
#

ngh. for a home lab with a single server though

#

it makes no sense

plain siren
#

It can run on a single server. Best part about it

waxen saddle
#

Is there Hardware pass through to VM’s in OpenNebula?

plain siren
#

Its all based on whatever you setup the service stack with.

tame carbon
#

@waxen saddle judging by the picture above, it doesnt matter

plain siren
tame carbon
#

since the features of your VM depend on what kind of hypervisor you are using

#

and kvm can just do hw passthrough

#

vmware too, I think

plain siren
#

Yeah it has some tight integrations with VMWare's entire suite

#

Which is cool if you use it

tame carbon
#

last few years this cloud craze

#

has gotten out of control

#

now there's a control panel for your control panel

#

nebula -> k8s -> some app

plain siren
#

Nebula is the Orchestration Interface, K8s is Orchestration Daemon

#

And some would still say Moores law is dead.... I say Containers happened.

#

OpenNebula > VMWare > K8s > Docker or OXP > ContainerD > The Container

peak cloak
#

some people overuse containers tbh

#

trying to dockerize everything

waxen saddle
#

Maybe. I’m able to host everything but 2 or 3 services in a container.

#

Haven’t quite figured out Ansible, LTSP yet.

peak cloak
#

The worst is when people don't actually understand what is happening in the container

peak cloak
#

packer too

waxen saddle
#

I even rolled my own container for OTA TV to Multicast streaming with SAP announce. That was a fun project.

#

One thing irks me though. For the life of me, I cannot get Portainer to use my CIFS NAS as storage. So all my configuration files are locked in the Portainer environment. It’s the gaping hole in my setup right now.

#

I’ve considered moving to another Docker manager, but I dunno where the actual problem is. The problem is that there’s always a permissions issue. I can get it so that some containers write to my NAS when they are initializing, but when the main process in the container takes over, it doesn’t have permissions to write to the NAS.

#

I’ve tried different PID’s for the container, mounting the NAS on the host, creating the docker user on the NAS, etc... extensive googling... maybe I’m not smart enough. Lol. Everyone else seems to be able to get it to work.

tame carbon
#

fuck amazon. seriously

#

rechargeable batteries, and the default purchase option: subscription

#

way to ruin the fucking environment

clear igloo
#

They offer subscriptions for socks and dust cloths too as the default 😛

tame carbon
#

I'm fed up with my mom buying single use triple-A's for this STUPID doorbell

#

it rarely rings, and needs a new battery every 2-3 months

little schooner
#

@tame carbon my smart doorlock is in the same situation

#

Except it wants 4 AA batteries!!

#

Dies pretty quickly. Like 2 3 months as well

peak cloak
#

we just have an old-fashion wired doorbell and just a good ole lock

little schooner
#

@peak cloak dumb locks still have their place in life, yes

waxen saddle
#

Wired smart locks would work pretty well too (with manual override), but companies just don't sell those.

hollow marlin
clear igloo
little schooner
#

Which one is that

clear igloo
#

Kwikset 910

tame carbon
#

@clear igloo you can get single use lithium cells in AA format

#

though thats only for things that you dont want to replace batteries for that often

#

like an LED headband

clear igloo
tame carbon
#

I have one that has been lasting 7 years xD

#

used it countless of times

clear igloo
#

wow!

tame carbon
#

retains charge much better

clear igloo
#

One thing I'll never buy again is Amazon Basics AA batteries. half the pack worked fine and when I replaced them at least one of every battery in the 4 packs exploded

tame carbon
#

dont buy basics at all

#

I boycott that shit

#

its often worse quality

#

and its amazon's master plan

carmine moss
#

i just get ikea batteries

clear igloo
#

oh, I remembered wrong, it was Energizer bulk pack batteries

carmine moss
#

they are rebranded panasonics where i live

tame carbon
#

@clear igloo energizer is a scam

#

xD

clear igloo
tame carbon
#

@clear igloo as for portable power, besides that stupid doorbell, everything here is with lithium cells

#

I have one of those battery banks

#

you can just put in an 18650 cell

#

and have 3200mAh

#

those cells are just far easier

#

they can do much higher current, hold more charge

#

and recharge quickly

carmine moss
#

i wish i had 18650 in some devices they are great

tame carbon
#

I used them in my vape

#

and now for everything xD

carmine moss
#

they are pretty cheap in battery banks 2 euro and a bit per cell

tame carbon
#

cheap cells are a fire hazzard

#

I currently have a batch of Sony VTC6 cells

#

30A, 3000mAh

#

I was using Samsung INR-18650's before

#

those are 25A

#

@carmine moss with cells, especially from dodgy sources, you really want to manually test them

#

and cycle them through once, measuring how much capacity they take, and if they heat up or not

carmine moss
#

they are 8.14Wh 3.7v 220Mah cells in those battery banks

#

unbranded tho

tame carbon
#

they sometimes sell 5A cells as though they are 20A

#

and if you overcurrent them repeatedly, and next time you go to charge them, you start a fire.

#

@carmine moss 220mAh ?

#

KEKW thats next to no charge at all

carmine moss
#

2200

#

forgot a 0

tame carbon
#

3.7V is nominal voltage for all 18650s

#

only interesting points are capacity and max current

#

4.2 is full, 3.2 is empty

#

< 3.0V = dead

#

@carmine moss I thought the video LTT made on their lithium battery thing, to be very irresponsible

#

they bought a bunch of thirdparty cells

#

and just put them in a bank

#

giving absolutely no care to cell imbalance

carmine moss
#

yeah that is a problem

tame carbon
#

like, if you put 50 cells next to eachother

#

and one of them starts a fire

#

you have a chinese firecracker

#

Watch 30 seconds of this ^

#

xD

carmine moss
#

yeah batteries are a risk a lot of times at least 18650 are somewat safer vs other lithium batteries

tame carbon
#

lithium is very reactive

#

and once it gets going

#

you aint putting it out

#

18650's are lithium ion

#

I think you're talking about lithium polymer

carmine moss
#

yeah that's the problem also cheap laptop batteries use bad 18650's

tame carbon
#

LiPo's expand and then burst with a ball of flames

carmine moss
#

and then stores sell you cheap knockoff ones saying they are real for laptops

tame carbon
#

amazon doesnt even permit the sale of lithium ion anymore ;P

#

or any lithium batteries for that matter

#

like, they are not toys.

#

they can potentially be a fire hazard

carmine moss
#

yeah people don't know how to take care safly of them

tame carbon
#

and with the dumb shit you see on youtube these days

#

good xD so normies at least cant get their hands on some

carmine moss
#

there is a channel called my play house he makes a lot of lithium ion banks but even what he does is sometimes problematic

tame carbon
#

as long as you take safety precautions

carmine moss
#

at least he is being as safe as he can he just has used some bad gear at times

tame carbon
#

only thing you really need to contain a lithium fire

#

is a steel barrel where you can dump the shit in

#

to let it fizzle out

carmine moss
#

he does it in his basement of his old house so yeah

tame carbon
#

water is the single worst idea xD

#

@carmine moss this is the true ali-express experience: https://www.youtube.com/watch?v=WOwhah8AifU

A video recently appeared online showed one Chinese family's electric scooter exploded while being charged at home.

The video, shot by the family's surveillance camera installed in their living room showed the whole family were sitting at home Sunday afternoon when smoke came out of the scooter being charged in the living room, accompanied by ...

carmine moss
#

Yeah those are a safety risk

wheat solstice
#

Buying a house soon and it's all wired up already with ethernet. My friends are saying that ubiquiti is basically the best way to go, but it's looking like to get a basic setup on Ubiquiti will cost £1000+ anyone have any suggestions? is it worth it?

peak cloak
#

ubiquiti unfi imo is eh

tame carbon
#

mikrotik is much cheaper

#

and just as versatile

peak cloak
#

unifi is "easier"

tame carbon
#

its just a bit less fancy config

wheat solstice
#

I mean the main stuff I want is nice handover between multiple access points, and some way of banning all my smart home devices from the internet

peak cloak
#

multiple APs can be done pretty easily (but not fully seamless)

tame carbon
#

mikrotik doesnt have seamless roaming, but AP handover is like 100ms

peak cloak
#

and for smart home that's also easily done with vlans

tame carbon
#

and mikrotik also has support for multiple antenna setups

wheat solstice
#

so the microtik takes 100ms to hand over, but the unifi stuff can do it seamlessly?

tame carbon
#

@wheat solstice well, the idea with seamless roaming is that the AP suggests to the phone that it should switch

peak cloak
#

truly seamless requires r/k support?

tame carbon
#

without 802.1rk support, the phone just switches to another AP

#

but mikrotik is smart enough to hand out the same IP, and immediate update the arp table

#

so you don't notice it

#

IEEE 802.11r-2008 or fast BSS transition (FT), also called fast roaming, is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure handoffs from one base station to another managed in a seamless manner. It was published on July 15, 2008. IEEE 802.11r-2008 was rolled up...

#

but even without this, experience is still good

wheat solstice
#

I see, I mean the main thing I'm hoping to avoid, I used to have a basic setup with two routers with the same SSID, but the laptop/phone would absolutely cling to whatever it was attached to. So it'd stay on the downstairs router when upstairs, and you'd have to manually reconnect to get it to stop being silly.

tame carbon
#

yeah but those are independent no?

peak cloak
#

Your TX power may have been too high?

wheat solstice
#

yea they were just normal boring routers with nothing fancy

tame carbon
#

those are remote APs

#

you just provision them within a single network

wheat solstice
#

I think I should definitely investigate microtik as well though. I'm a programmer by day and a fan of more open things, I have been a bit hesitant of the unifi stuff because it feels very iphoney.

tame carbon
#

and the router controls the access points

#

so when a phone moves to another area, it should just kick it off and move to the other AP

#

@wheat solstice what kind of net speed do you have?

#

and how many APs do you plan on putting out?

wheat solstice
#

@tame carbon 500mbit, hopefully going up to 1gbit in the future once it becomes available.

APs will be between 2 and 4 I would think.

tame carbon
#

like their standard dual chain access points cost about 60 bucks each

peak cloak
#

I have the ER-X myself

tame carbon
#

and the router, you can go as wildy as you want

#

60 bucks for a 5 port gigabit router

wheat solstice
#

@tame carbon I also have a home server (Think NAS) that I'd ideally like on a 10g link.

tame carbon
#

@wheat solstice lol you should get the router I have, since my stuff here is 10G as well xD

tame carbon
#
wheat solstice
#

@peak cloak probably copper, since I'd have to run the cable, so it'd be weird to run SFP links in the walls.

tame carbon
#

this thing mops the floor with the ER-X

peak cloak
#

much cheaper

#

SFP+ is just a connector

#

then you put in a module

#

which can be fiber, copper, etc.

tame carbon
#

if you get a router with 10GbE RJ45, instead of SFP+, you can't do fiber

#

SFP+ can do both RJ45 or Fiber, depending on the module

wheat solstice
#

ah, so I could do SFP -> ethernet -> SFP -> Switch in the office -> SFP -> Home server?

tame carbon
#

@wheat solstice SFP+ is just an interface

tame carbon
#

you plug a module in there

#

@wheat solstice this would be my first recommendation

#

10x 1G

#

and 1x 10G

#

$190

#

I have this one at home

#

very pleased with it

wheat solstice
#

yea, seems reasonably priced and available in the UK too which is good.

So that's my router. The one 10G port can go to my office, and I guess I use one of those ports as the WAN port to the modem.

tame carbon
#

@wheat solstice you only use this for routing

#

if you want more 10G connectivity

#

you'd use a switch

peak cloak
#

router on a stick

#

for 10G

#

actually no

tame carbon
#

@wheat solstice and the place you plug your cables in doesnt really matter ,since VLANs are king.

wheat solstice
#

VLANs hurt my brain coming from the typical land of Asus routers 🙂

tame carbon
#

Its not that complicated really

wheat solstice
#

Yea, I'm sure I'll wrap my head around it lol

tame carbon
#

I could help you set some up on this gear

peak cloak
#

yeah

#

let me find a diagam I made

tame carbon
#

@wheat solstice I have this one hanging in my office:

wheat solstice
#

Good news is I've come at this problem nice and early, probably at least a month out from moving. So I got time to learn 🙂

tame carbon
#

@wheat solstice on this, I plugged in my router and server with 10G, as well as my workstation

tame carbon
#

your actual network is a virtual network ontop of the physical network

#

physical ethernet is just to connect them up

peak cloak
#

Here I was also explaining the difference between vlan and subnet

wheat solstice
#

I see

peak cloak
#

a subnet goes onto a vlan

#

vlan is just a way to have multiple L2 networks on one pysical link

#

all the switch and router do is add/remove a tag to an ethernet packet

tame carbon
#

vlans are ethernet networks (layer 2)
subnets are IP networks (layer 3)

#

vlans just add some extra data to your data packet

#

with a number between 1 and 4095

#

if its 1, that means there's no vlan active, that's regular ethernet

#

@wheat solstice imagine you have a switch with 10 ports and a single highspeed port to the router

#

you can give each physical port a different vlan ID

#

and then the cable to the router, can have 10 virtual interfaces on the router's side

#

SFP+ interface, with multiple vlans associated

#

and they behave like ethernet interfaces basically

wheat solstice
#

I see, so to start with I'd probably need the RB4011iGS+RM, A couple of switches (one for the garage where ethernet all terminates, one in my office) and some APs, although it seems like microtik doesn't have any WiFi 6 aps yet 😦

tame carbon
#

wifi 6 only really starts making sense if you many devices

#

like more than 10

peak cloak
#

or in a congested area like an apartment or city

wheat solstice
#

I definitely have more than 10 devices 🙂

tame carbon
#

it helps reduce latency

#

but if you have more access points spread across the house

#

it shouldnt be an issue

peak cloak
#

@wheat solstice I know tp-link now has wifi6 APs

#

I have an omada AP myself

tame carbon
#

these are pretty cost effective

peak cloak
wheat solstice
#

yea they do seem to be fairly cheap, like £50. On this basis seems like I could rig my house up for less than half the price it'd cost me to do it on unifi, pretty decent saving

peak cloak
#

^and you can install or buy a controller for more seamless roaming I think

tame carbon
#

@wheat solstice all those devices run the same operating system

#

and you can use your RB4011 to control those APs

peak cloak
#

I only have 1 AP so I didn't use the controller

tame carbon
#

as a group

#

you can set up multiple wireless networks across them

#

like a guest network, isolating them to a seperate vlan and subnet

#

and even limit their bandwidth

#

xD

wheat solstice
#

Yea, I think choosing a platform is important right? That's the whole allure of unifi in the first place, that you have one central place to control everything, and you can identify every device on the network because all the APs/switches talk to the controller, etc

peak cloak
#

I have things all over the place

tame carbon
#

single vendor is easier in most scenarios

peak cloak
#

router from ubiquiti (ER-X)

#

switch from D-Link

#

AP from Tp-link

tame carbon
#

switches dont really matter xD

peak cloak
#

especially managed ones

tame carbon
#

well yes

#

but they can all do vlans xD

clear igloo
#

Yah, they don't matter much outside of home features but in larger enterprise situations of course it can easily matter

peak cloak
#

yeah

#

at home it's fine

wheat solstice
#

what microtik switch would be recommended? May as well stay in house since I'm looking at a microtik switch, and microtik APs

tame carbon
#

how many ports? xD

wheat solstice
#

12 would probably be enough, 24 would be nice

tame carbon
wheat solstice
#

the place has ethernet in every room (unfortunately cat5e) and also my office consumes a reasonably quantity of ethernet ports (6+)

tame carbon
#

wait no, I changed the link click again

wheat solstice
#

fun, would be nice to have PoE somewhere too for cameras

tame carbon
#

I mean

#

this switch is $200

#

the PoE variant is almost double the price xD

clear igloo
#

PoE for APs is definitely worth it

wheat solstice
#

still cheaper than unifi 😂

tame carbon
#

but that is true

peak cloak
#

yes, poe is great

wheat solstice
#

and yea, will need PoE for APs too

tame carbon
wheat solstice
#

works out at £531 for the same stuff that'd cost me £1167 over at unifi

tame carbon
wheat solstice
#

guess I gotta hit up some youtube and investigate the microtik side of things 🙂

tame carbon
#

and mtik is Latvian, so probably no NSA backdoor xD

wheat solstice
#

don't suppose the firmware is open source, I can dream

tame carbon
#

@wheat solstice sadly no

wheat solstice
#

that's one thing that annoys me, I'm moving from a nice open source router to a proprietary one, I hate that as a thing

tame carbon
#

RouterOS is based on some older version of linux

#

but its pretty much in house

#

but it does have an API

#

and scripting capabilities

wheat solstice
#

I see, not as bad then, assume you can SSH into them and do things too if you want

tame carbon
#

you use their config tool Winbox

#

but they also have cli

#

winbox is just a graphical shell around the cli

wheat solstice
#

😂 they only have a Windows version of this software?

tame carbon
#

winbox runs on wine just fine xD

wheat solstice
tame carbon
#

it just has an oldschool look

wheat solstice
#

yea don't mind too much it being oldschool, just a bit bad that the software isn't ported to Linux, especially considering it's a tool for network admins, who tend to be the type of people that run Linux 😂

tame carbon
#

well, its using linux internally

#

and you can install RouterOS on x86

#

just need a license

wheat solstice
#

I see

tame carbon
#

the RB4011 is a quadcore arm cpu

#

but some of their devices use MIPS

#

mikrotik really caters to the lower and middle segment

#

they have really sharp prices for enterprise features

wheat solstice
#

I wonder what the pfSense people typically do. I used to run pfSense like a decade ago and it was very nice.

tame carbon
#

pfsense has one major issue

#

same with RouterOS on x86

#

you dont have any hardware acceleration.

#

the RB4011 can route full 10gbit/s with 25 firewall filter rules

#

if you do that on pfsense, good luck xD

wheat solstice
#

makes sense

#

yea, I remember I ran pfSense on a potato and it chugged at rather low speeds 🙂

#

but 10 years ago that obviously didn't matter much.

tame carbon
#

I have one of these as a portable router

#

I have a couple presets in mine, where I can just plug it in

#

and it sets up a VPN tunnel to my home

wheat solstice
#

Back when I used to travel a lot I had one of the popular TP-Link travel routers flashed with OpenWRT and an OpenVPN client, was pretty cool

#

yea, basically the same thing, but newer 🙂

tame carbon
#

but that hAP mini costs $20

#

and it can route 300mbit/s

#

3x 100M ports

#

and it can run off a usb port

#

RouterOS 7 will add wireguard support

#

but thats still beta right now

wheat solstice
#

The other thing that might help me understand a bit more, this microtik router we are looking at - how does it differ from the typical asus router I'm used to? I understand it doesn't have WiFi or a modem built in, but what else?

tame carbon
#

@wheat solstice most consumer routers are just a bridge, two kinds of interface groups: WAN and LAN

#

and a NAT between them

#

it can't really do anything else

#

port forwarding

#

thats the only other thing most of them support xD

#

but thats firewall

wheat solstice
#

makes sense, I mean that's what I'm used to and understand atm

tame carbon
#

if you have a single public IP

#

your router will masquerade the connections when you go to the internet

#

if you look at these two rules

#

general internet, translates outgoing connections

#

and the other rule, is for port forwarding

wheat solstice
#

what's masquerade? 🙂

tame carbon
#

You know what port forwarding is right?

wheat solstice
#

yup

tame carbon
#

Public ip + port -> local ip + port

#

that's what we call destination NAT

wheat solstice
#

map incoming traffic on port X to IP Y on port Z, makes sense

tame carbon
#

yeah, NAT is network address translation

#

so the other way around

#

so from a local address, over a shared IP to the internet

#

the router basically connects on your behalf

#

and any packets that you or the server send, get translated

#

that's source-NAT

#

and the technique is called Masquerading

peak cloak
#

we basically need to NAT because we ran out of ipv4 addresses

tame carbon
#

xD

peak cloak
#

ipv6 is a whole other story

wheat solstice
#

Oh I see what you're saying, so masquerade is the routers process of forwarding packets back and fourth between the computer on LAN, and computers on the internet

tame carbon
#

well, I think the last part you said, is a more general description for NAT as a whole

#

but yeah

wheat solstice
#

yea think I get it

tame carbon
#

srcnat is for outgoing traffic

#

dstnat is for incoming traffic

wheat solstice
#

so your screenshot is essentially a port forward for a local minecraft server?

tame carbon
#

first tab is the filter rule

#

and the 3rd tab is the Action with items that match the filter

#

Clearly it's a lot more configurable, I just have a little learning curve ahead of me 🙂

tame carbon
#

and NAT is only a small part of the rest of the firewall

#

that's also highly configurable

#

luckily, default configuration that ships on them

#

is pretty much set up for a home network

wheat solstice
#

what useful stuff can I do with it that I couldn't do on a typical router? might help me to understand more, it's still a bit of a black box to me lol

#

and that's good too haha, a default that works and I can figure things out as I go

peak cloak
wheat solstice
#

yea but I'm just thinking a real world example

peak cloak
#

so it's an actual router not just a NAT device

tame carbon
#

@wheat solstice best part, routerOS has a single window with the 'normie' configuration

peak cloak
#

let's say in my example I have a WAN server VLAN

tame carbon
#

xDD

#

if you use quickset after doing advanced configs

#

it breaks your entire install

wheat solstice
#

yay for normie configuration

peak cloak
#

All my server vms are on that VLAN so I add firewall rules so if case the WAN server get's infected it can't see my home network at all

tame carbon
#

@wheat solstice I have a public /29 range

wheat solstice
#

@peak cloak ah I see, yea I'd want to do something like that for smart home devices, block them all from the internet and only have them visible to my home server (running home assistant) - does sound like something I couldn't do on a normal router, but which would be useful

tame carbon
#

8 public IPs associated to my router

tame carbon
#

and I have an isolated vlan for that subnet, each virtual machine on my server has its own public IP

wheat solstice
#

@tame carbon I have a /29 too, although isn't that 5 IPs not 8?

tame carbon
#

6 addressable hosts

#

one of which is your router

#

but you can use NAT on the router's IP

wheat solstice
#

yea, and one is the gateway

tame carbon
#

yea

#

but you can still use NAT on those xD

wheat solstice
#

I don't have any use for the /29...I'm just using one of the IPs atm >.<

#

took a bit of fiddling to get my boring asus router to work lol

wheat solstice
#

@peak cloak they came free with the connection lol, I got the business line since I wanted static IP and 12 hour SLA 😄

tame carbon

because I was hating on asus

#

because they build shit routers.

Wd gold worth the money ?

#

Western Digital Gold 18TB 512MB Sata III WD181KRYZ

clear igloo
#

If it's not more expensive over a red version then I'd go for it, they are supposed to be better rated from what I can tell

#

Gold can do a bit more read/write over the red pro and has longer MTBF and minor other spec differences

lean pebble
#

616$ each

#

2050 each in my currency

clear igloo
#

red pro is $610 on amazon so basically same price then

Someone mentioned power draw is a tad higher on the gold though but only by a few watts

Looking for a network card, since I think my MB's ethernet is being dumb?
MB: ASRock AB350M Top slot has a GPU, so all that remains is the lower slot, not sure what the slot is or whats compatible

Bottom slot is pcie 2.0 x1

Any pcie x1 network card should work fine

@ripe coral When it comes to Wireless, look for PCIe Adapters with AX3000 Chipsets

Wired, you want Intel 350 or perhaps an older 82574L Controller. I350 is the go-to

I don't like pfsense

just get a dedicated router with an OS tuned to the hardware

@peak cloak quad core pfsense seems to work for me though I don't have a gigabit line to test

Across subnets

Does that require more than the router itself to do?

well router and 2 devices

I mean I guess I could open laptop and desktop and test

Yeah hmm

I should test that

@hardy sandal I have a $190 RB4011

Hi guys. My friend is new in networking and I am trying to explain him connection between application, ports, IP, MAC and internet interface. Does anyone of you have any charts which I could use? I know mr google is helpful but I need something which is not oversimplified.

peak cloak
#

also

#

the osi model

south escarp
peak cloak
#

Ah alright

south escarp
# peak cloak

He knows osi. But he has problems to understand connections between layers. The chart I would need had to look something like this

peak cloak
#

this is good

#

basically everything gets stacked on top

#

routers for example modify the MAC header

#

and routers that do NAT modify the IP header also

south escarp
#

Yeah. That is not bad.

#

Its complicated since teacher doesnt care about people which arent tech dedicated.

peak cloak
#

what class?

#

networking?

south escarp
#

Mechatronics. Basicly from ground up HW level to software level.

peak cloak
#

ah

#

I'm a HS junior for mechtronics as well

#

although we don't do anywhere as depth

#

I just like networking and learn it by myself

yeah you can never learn everything

it's too complex

@peak cloak Anyway. Thanks for help. I will try to make it to good use.

# peak cloak

I know layers 7, 6, and 5 all happen basically at once in the entire data PDU process. Makes sense as to why the other layers are the main focus. 🤷‍♂️

peak cloak
#

yeah

#

the upper layers are just part of data

lone sun
# peak cloak the upper layers are just part of data

Yeah, I mean, it has to happen at once when you think about it. If the session between nodes is established before the security protocols can take action, then the session can never be secure. Its compromised right from the jump. So it either happens all at once, or shouldn't happen at all.

Hello guys I'm trying to build a cheap server for NAS and plex
Maybe hosting more stuff on it and i found this
Do u think it's good cus im not experienced with xeon

thick minnow
#

link?

naive terrace
sullen elm
#

wait

#

that comes with a mobo, ram, cpu and hestasink?

#

if that's the case

#

it does not look very attractive

#

te heatsink looks trash

#

and 8gb ram is not enough for seamless plex streaming

naive terrace
#

I have a 212 fan so i dont really care about that one

sullen elm
#

ok

#

maybe upgrade the ram

#

do you need 10gbe ethernet?

naive terrace
#

No

#

1gig is enough

sullen elm
#

ok

naive terrace
#

Why i need more ram?

sullen elm
#

then the mobo looks fine

#

I am a bit skeptical about the ram though

#

16gigs is perfect

#

8gigs is not enough

naive terrace
#

I found another combo with 16 gb ram and better cpu

sullen elm
#

link?

naive terrace
#

But it cost 180$

sullen elm
#

the other one?

naive terrace
sullen elm
#

because I am not familiar with the currency

naive terrace
#

Yeah that's why i mentioned the price

#

First one is 120$

sullen elm
#

this looks way more perfect

#

the second one

#

If you can afford it

#

go with the second bundle

naive terrace
#

I dont think the cost is justified but again I dont really know much about xeon

sullen elm
#

the fisrt one is fine

naive terrace
#

What i need is a nas to backup my data

sullen elm
#

4 cores 8 threads

naive terrace
#

Yeah

sullen elm
#

at 2.4GhZ

#

it's enough for plex decoding

#

at 1080p

#

but it has a 80w TDP

#

that's why I am concerned about the cooler

#

It's also an old model

#

with only DDR3 support

#

so you eill have trouble upgrading

naive terrace
#

Should i find a core i3 or core i5 for example 2nd gen instead?

sullen elm
#

If you eant just plex

#

then an i5 would be an option

naive terrace
#

It's mainly NAS and maybe plex

sullen elm
#

hmmmm

#

I f you are on a tight budget then go with a an i5

#

maybe a second hand i7 4th gen

naive terrace
#

That cost a lot

sullen elm
#

second hand i7-4790K

#

I think they go around 80 dollars

naive terrace
#

Yeah about 280$ with the mobo

sullen elm
#

Is that ok?

naive terrace
#

No that's a lot

sullen elm
#

then go with the second bundle

naive terrace
#

Still need ram and the drives

sullen elm
#

go with the second bundle then

#

and then the drives

naive terrace
#

212 supports that cpu?

#

Coolermaster 212X i think

sullen elm
#

check coolermaster's docs

#

I am not sure about that

#

but on the second bundle, the cooler is ok

naive terrace
#

Ok i will check its manual

#

Thanks for the help

sullen elm
#

no problem

#

stay safe!

#

@hardy sandal I'm a big fan of them. They have very good prices for the lower and middle segment

#

a 10gbit router for under 200 bucks, yeah. beats what you can build on a budget with pfsense

#

and the software, RouterOS has quite a lot of features

#

@sullen elm I self assembled a small server with a Ryzen 2600 on a mini ITX board

hardy sandal
#

@tame carbon whatabout cisco ?

tame carbon
#

@hardy sandal much more expensive

#

their high end routers make little sense for SOHO environments

#

even their small business solutions are "Request a quote" or "Contact sales"

#

@hardy sandal my views on this are biased though. I prefer cost effective solutions, and mikrotik is king for me in this regard

#

cheap, fast, reliable and tonns of options

clear igloo
#

Heating and internet all in the same unit!

tame carbon
#

@clear igloo you can just use a pfsense box instead

#

cheaper, same BTU output

#

get one of those DDR2 xeons

lol, but you can't do 400g on pfsense

Okay wrong use of words

tame carbon

@clear igloo I called them up yesterday, spoke over the phone with the boss for 10-15 mins

they look for java developers who came into this job through hobbyists experience

That's awesome

so I'm the kind of person they are looking for

@thick minnow ya

i wanted to study electrical engineering first xD

programming was just a hobby

clear igloo

I started dabbling in programming around that age too, I was going to be a game developer at first

tame carbon

games never interested me

I'm more interested in the nitty gritty data stuff

clear igloo
#

Thankfully DeVry was such a massive pile of teaching I stopped halfway through my degree and left that behind. Of course years later I'm now doing python programming as a network engineer lul

tame carbon
#

@clear igloo and i fully understand for them to ask for developers that made a job out of their hobby

#

because the people in university were people with windows on their laptop

#

and 0 programming experience

#

60% dropped out the first year

clear igloo
#

Sounds about right

#

the best students are the ones who are a gigantic nerd before they started university

they suck at business courses and design

and excel at coding and architecture design

they can see the bigger picture far better

might as well just write the password on a post-it note

also that may or may not have been a joke

it does

USAA's online banking app still only allows passwords up to 12 characters

tame carbon
#

arbitrary limits

untold elbow
#

and ive been giving them grief about it for several years

tame carbon
#

who gives a shit about pw length lmfao

#

my systems would support passwords up to 1024 or however much ram

untold elbow
#

it's a holdover from ancient encryption standards that broke if you use more than X characters

tame carbon
#

since I only store hashes anyways

#

them setting a 12-char limit

#

sounds like they just store password in cleartext.

untold elbow
#

dunno, i give them the benefit of the doubt... partially because i don't want to believe anyone is that stupid, but partially because i do all my banking with them

tame carbon
#

there's usually a test for this kind of foolish system

#

if you request a "Forgot password"

#

and they email you a cleartext pw

#

thats instant red flag

untold elbow
#

no, they don't do that, they do a normal reset link

#

that's a huge red flag, yes

site that do that, i stop using right away

tawny hemlock
#

yeah i new that would work im going to by 1000ft of cat 6

peak cloak
#

gig ethernet only supports up to 100 meters aka 300ish feet

tawny hemlock
#

xd 1000 meeters total it is a 16 poart swithc

peak cloak
#

ahhh

#

yeah

#

I have 1000 foot roll of cat5e

#

regeret I didn't do cat6

tawny hemlock
#

and im prety surer it is cat 6 1000ft for 10gb

peak cloak
#

?

#

wut

#

for 10 gig it's even less

tawny hemlock
#

ah

peak cloak
#

55 meters

tawny hemlock
#

ok

peak cloak
#

and for 10 gig you might as well just do fiber

tawny hemlock
#

cat 6a is lots cheper than fiber

peak cloak
#

umm not really

tawny hemlock
#

but fiber got the transivers

peak cloak
#

copper 10 gig end recievers are expensive

#

10 gig transceivers are cheap

#

I would say the sfp+ pcie cards are the most expensive

#

also good luck finding a cheap 10 gig copper switch

#

283.99 for modem switch cable and conectors

peak cloak
#

modem?

tawny hemlock
#

for 16ports of 1g

#

modem

peak cloak
#

why modem?

#

why do you need a modem

tawny hemlock
#

because im not using the router from my isp to run a 1g switch and i kinda need a conectoin

peak cloak
#

ohhh you are talking about what you are using

#

@tawny hemlock you need a router too

tawny hemlock
#

i have a acses point the modem is to the osuside world

peak cloak
tawny hemlock
#

why

peak cloak
#

ok, let me explain

tawny hemlock
#

an aces point is just a router but no modem

peak cloak
#

so you get one ipv4 IP from your ISP, a router NATs that one ip to multiple IPs for your LAN among other services like DHCP which hands outs ips. For ipv6 it routes between the 2 subnets and does router-advert

peak cloak
#

An access point is just for wifi

#

You still need a router

#

I have an ER-X

#

no wifi

#

just a router

tawny hemlock
peak cloak
#

mikrotik's HEX-S also seems like a good choice

peak cloak
#

you still need a router

tawny hemlock
peak cloak
#

that's a wireless router then

#

you would need to route all your traffic through that

tawny hemlock
#

Yeah it is i thought it was something totally different my dad bought it without nowing anything about networking

peak cloak
tawny hemlock
#

Can you send me the neweg link to to yours

tawny hemlock
#

The router

tawny hemlock
#

I'm doing this all on rack shelf

peak cloak
#

ah nice

#

mikrotik also has some nice things

#

their Hex-S is also nice

#

although none of these routers are simple

#

and if you want to setup ipv6 for example you need to use the cli

tawny hemlock
#

Yeah lol so two ap router modem switched cables wall plates conectors and switche 419

tame carbon
#

@tawny hemlock those mikrotiks allow you to configure multiple access points as a single network

#

and you could have a single router like the hEX S as a controller to those APs

#

each cost around 60 bucks

#

and you can just add as many APs as you want

#

even configure guest networks and such

#

unifi does this too, but mikrotik is a bit cheaper

waxen scroll
#

@peak cloak and dont forget to make an ipv6 firewall

#

😄

tame carbon
#

latest tplink stuff can do it too, Omada or Omeda I think, but who cares xD

waxen scroll
#

i didnt and then one day thought about it and was like OOPS

tame carbon
#

if you install the v6 package on mtik

#

you also dont have a default fw

tame carbon
#

and many of these ^

tawny hemlock
#

plug evrthing ito the swtich switch to router router to modem

peak cloak
#

for a flat network yes

#

but that's as basic as you get

tame carbon
#

@tawny hemlock depending on the modem you have, you might be able to disable its router functionality and use it as a bridge

#

in that case, you can enter your ISP's credentials in the router itself

#

and even control your own firewall

#

because the built in ones from the ISP are total shit

tame carbon
#

yeah PPPoE

peak cloak
#

usually it's just DHCP

tame carbon
#

though some cable modems also support bridging

tawny hemlock
#

it is staying at my parents house when i move out dosent need to be that fancy

tame carbon
#

I mean, how much coverage do you need?

#

if you need multiple access points and want a reliable experience, those mikrotiks are best value

#

unifi setups are very expensive

#
#

you could also get one of these

#

it has an internal wireless as well

tawny hemlock
#

1788 sq ft

peak cloak
tame carbon
#

@tawny hemlock mostly matters how many rooms you have

peak cloak
#

but not as fancy as blob's lol

tame carbon
#

walls are your enemy

#

if you didnt have walls, you could put one ap in the middle

#

and have coverage everywhere

#

1788sq ft isnt a lot

#

ideally you just want the APs near where you are most likely going to use it

#

1 or 2 ought to do it

#

with $120 you'd be done

#

get a hAP ac2 and a cap ac

tawny hemlock
#

yeah ill do 2 ap one on each floor because it will be fine in my room wich is on floor 2.5 will be fine because i use lan most of the time

tame carbon
#

can you run cables?

#

like, these cAP ac's are relatively cheap

#

and they support PoE

#

if you have a PoE capable switch, you dont have to plug in adapters in the AP

#

easier with ceiling mounts

#

ceiling panels are the best

#

cus you can just toss the AP on top of them xD

#

love that in office areas

tawny hemlock
#

the ap come with a peo injector

tame carbon
#

yeah

#

but a PoE switch could reduce cable mess even more

#

they would have it built in

#

but if you dont mind having a couple of those injectors

#

they just use DC

tawny hemlock
#

one stipulatoin it needs to have a us wall plug

tame carbon
#

if you order mikrotik in US, you probably get one of those yeah

#

they are an EU company

tawny hemlock
#

how much are they per ap

tame carbon
#
#

those things can also function as a router xD

#

they only have two ports though

#

they have a quadcore cpu onboard :P

peak cloak
tame carbon
#

1.9gbit/s ?

#

I mean

#

its ment as a CAP (controlled AP)

peak cloak
#

huh

tame carbon
#

but it can route xD

#

so you could get two cAPs

#

or a cAP ac, and a hAP ac (it has more ports)

#

this guy has same routing speed as those APs

#

it also has wireless

#

but it has more ports

#

and a VPN accelerator chip onboard

tawny hemlock
#

i dont need the fancy gear

tame carbon
#

@tawny hemlock this thing costs $69

#

same price as the APs

#

just saying, you can mix and match.

#

but if you just get one device, then I would recommend the hAP ac2

tame carbon
#

what kind of net speed do you have?

#

and I don't touch tplink stuff with a 10 foot pole

#

I've thrown away 3 tplink routers so far

peak cloak
#

tplink business stuff is fine

#

I have it

#

no issues

#

works perfectly fine
