Got the VPS set up, have the 4c24g ARM instance running, setup as pihole+unbound, openvpn community server, tailscale DERP relay server and zerotier MOON relay server all on the same instance ^^ OCI is awesome. Still under 300MB RAM usage and barely any CPU usage, linux is amazing. I can do a lot more with this stuff too.

Openvpn comm. server (not the access server) wasn't easy to setup the way I wanted it to work, but I managed to make the server and client configs such that I can either use it as just a tunnel to my VPS (w. pihole DNS) and as a route to other friends connected to it, or route all internet traffic through it as well, however I want (2 diff. configs on client side).

Also, ZT Relay server is well optimized, friends now get around 40ms ping to my self hosted minecraft server, no matter what's going on. Next plan is to move the mc server itself onto the cloud and limit it's access through openvpn tunnel only.

So - thank you for this suggestion ... 😄 Helped me out a lot!

Does anybody know how to bridge the LAN port on a Mikrotik device running RouterOS 7 to the wireless? Using a Groove52 ac and trying to use it was a wireless AP and router to run a mixer but in the default Home AP and WISP modes that seem like they would be the best options I am unsure how to bridge the single LAN port so I can communicate to the wired device I need to acce3ss

The only modes that offer to bridge the LAN are supposed to be used to bridge networks wirelessly (aka the antenna is set for P2P mode, not broadcasting SSID

Learned about SANs today. Saw something in a picture about them then hit google. Trying to actually visualize the difference from a nas. Like i get it, but only mostly. Would something like Whonnok (or however you spell it) be considered a SAN? Or is it just a term noone really uses anymore

slow pivot Sep 9, 2022, 11:59 PM

#

SAN is usually more block storage over network providing storage to servers etc whereas NAS is providing network shares/storage to end users.

#

Admittedly the difference seems to be more blurred these days

tidal frost Sep 10, 2022, 12:05 AM

#

The backblaze article i was reading just made it seem like a nas but with so many features you needed another machine to handle metadata

#

https://www.backblaze.com/blog/whats-the-diff-nas-vs-san/

slow pivot Sep 10, 2022, 12:08 AM

#

Right, block devices are basically drives :)

tidal frost Sep 10, 2022, 12:08 AM

#

Like it says you mount them as local storage too, but im pretty sure i did that with my Unraid server already in windows. I may have technically added "shortcuts to different directories on the nas" or whatever but it functions the same

slow pivot Sep 10, 2022, 12:09 AM

#

So think iSCSI for example, is something a SAN would deliver and the backend might be dozens of servers and hundreds of drives for a single disk mount

tidal frost Sep 10, 2022, 12:10 AM

#

slow pivot Right, block devices are basically drives :)

I kinda figured. Blocks on a single drive being storage areas, so when you scale it up those areas become dedicated drives.

🤔 When does pinging the loopback address become relevant for trouble shooting? This one dude claimed it can be pinged to see if the NIC adapter itself is working, but I'm not sure how true that is.

waxen scroll Sep 10, 2022, 12:53 AM

#

lone sun 🤔 When does pinging the loopback address become relevant for trouble shooting? ...

its not

#

all it tells you is all links to the router are probably dead

#

it will not tell you a single link is dead

#

proper way is to ping loopback to check if the router is unreachable and SNMP or syslog to determine if there are single link issues

lone sun Sep 10, 2022, 1:11 AM

#

waxen scroll all it tells you is all links to the router are probably dead

😕So when the loopback says "unreachable", what is the next troubleshooting step exactly? Network+ didn't really explain the usefulness of loopback addresses that well. It just tells you to ping the default gateway to see if the modem/router is active.

waxen scroll Sep 10, 2022, 1:12 AM

#

if its a router at a remote site and its the only one, ask local contact to verify power, possibly reboot, and then call ISP

#

if its at a site thats still online, check the devices its attached to for port status. if up, is there a mac address learned? is there arp learned?

#

is the config wrong, does it need to be on another vlan

#

if you dont have a loopback that means you need to use multiple interface IPs to manage the device and thats a pain in the ass

#

if one goes down that IP wont work, so you need to use the next IP

#

with a loopback theres no problem like that

lone sun Sep 10, 2022, 1:16 AM

#

🤔 I mean, I'm not sure I even follow. 😅 Like, what if the loopback address is unreachable for your own personal computer or laptop? @waxen scroll

lone sun Sep 10, 2022, 1:39 AM

#

waxen scroll They're not used on hosts. Only network equipment

😕 I mean, I'm seeing some websites claim it has something to do with the TCP/IP stack in the operating system itself. And if its not reachable, it probably wasn't installed correctly. But it has nothing to do with the network adapter I now see. 🧐

#

And that's why some claim the loopback should be pinged first when troubleshooting connectivity issues? 🤷‍♂️

Got a question, my ISP provides a 400mbps connection (typically actually 450mbps), and I have had no issues for the past several months. Recently I noticed though, the connection specifically over ethernet has been on average 80-90mbps or less. This has me confused because I haven't found any issues with out cables, including damage or crimping. I haven't had any issues with packet loss either which I assume would be the case if a damaged cable was causing signal degradation. Does anyone have any ideas? Is it possible the ISP is throttling devices connected over ethernet? I haven't tried plugging other devices I don't normally use in yet.

copper laurel Sep 10, 2022, 5:21 PM

Hi everyone. In need of some advice. I do astrophotography and I use a mini computer that uses raspberry pi 4 and some software. It function on my phone using a WiFi connection but the problem is that I have to within ten foot for it to work. I'm at the point where I have everything set up and working at a permanent position. I wanted to run an Ethernet cable outside but considered an idea and then realised that if lightning struck near by that would cause issues. I'm under the impression that I would need to use armoured. I was going to bury it but I'm thinking because of the bends it would just be easier to run it through some PVC. Advise, please and thank you.

The best solution to this if lightning is a serious concern in your area is probably to use fiber media converters and run multimode fiber if the cost-benefit makes sense for your use case. Second best is an optoisolator which is basically that scaled down, you'd want one at both ends. Do keep in mind your power cables if you're running power out to the Pi as well. Probably overkill and none of this helps if your pi eats a direct lightning strike though in the case of fiber optic it won't be its fault

I had an issue with Google Wifi where it would randomly re-negotiate the port speed to 100Mb/s and leave it there. Get yourself a descent managed switch and you should be able to force the port speed instead of letting it auto-negotiate. This works well: https://smile.amazon.com/dp/B00K4DS5KU.

10/100 phy chips believe it are not cheaper - their use is so limited they get spun at significantly lower quantities, today I can buy 10k 1gig phy chips for less than I can buy 2k 10/100 phys. It baffles us at people still spin 10/100 devices. There are significant features that don't work properly at 10/100 - for example, modern cisco MGIG switches have a significant feature drop off if an interface drops to 10/100 - AVB being a big example.

I know nothing of the pricing, but I work in the industrial sector and 10/100 is still the defacto standard for most industrial communication bus protocols (Ethernet/IP, EtherCAT, Etc). Almost all the hardware we buy, thousands of drives a year, all have 100Mbps speed. I would imagine companies still putting 10/100 chips into their products at consumer level signed very long licensing deals for acquiring the hardware.

peak cloak Sep 12, 2022, 3:35 PM

yeah, cheaper for them

wooden condor Sep 12, 2022, 3:35 PM

#

but if i were to buy them TODAY, and look at something like a Marvel PHY, they are more than 2x the cost - now the one thing that probably is also holding them back is just simply respinning hardware design to support a new phy.

#

we see it a lot in industrial controls from rockwell for example - or even in the entertainment industry where because there is no need for more than a 15mb/s stream to an IP speaker, there is no reason to respin it and support a new phy

#

but the actualy cost of the phy itself is definitely not cheaper.

limber river Sep 12, 2022, 3:37 PM

#

wooden condor but the actualy cost of the phy itself is definitely not cheaper.

True, but rockwell just passes that cost onto the consumer at greatly inflated margins, so they have no need to change it.

limber river Sep 12, 2022, 3:58 PM

#

wooden condor well don't talk shit about their BOP network, i designed that! lol.

I think my biggest problem with Rockwell is that very few people in the entire company actually understand what it takes to implement their hardware in a real production environment, and when you find problems with it (which you inevitably will), their answer is almost always "too bad, we may fix that down the road in a few years". The other problem I have with them is the fact that they release alpha-level hardware/software to market, then flat-out refuse to do anything to fix it, forcing their distributors and implementer partners to come up with very expensive, elaborate work-arounds......but now I'm just ranting.

#

Take, for example, their network switches. They are 'supposed' to be Cisco rebranded hardware. What they don't tell you is that for whatever reason they didn't license all the software features, so the switches actually have less functionality than their equivalent cisco counterparts. Once you run into this limitation, you either have to change out all the hardware (with significant 're-stocking' fees for the stuff that you can't use) or you have to come up with band-aide workarounds to go without the features.

#

Ok....I'll stop now.

wooden condor Sep 12, 2022, 4:04 PM

#

I mean that's just generally manufacturers as a whole though isn't it? The development cycle is obscenely long for hardware solutions so if a. partner/distributor can work around that .

#

They aren't supposed to be, they actually are cisco switches, and if you have that problem, DM me, lol

wooden condor Sep 12, 2022, 4:04 PM

#

I jsut mean in general, like it's an issue with Cisco too

#

not that this every happens

#

but if cisco releases a product that has a shortcoming

#

it theoretically COULD take a year or more to fix through our dev cycle

#

and often by the time we've fixed it partners or even our sales teams have figured ways around the deficiency

#

that of course never happens

limber river Sep 12, 2022, 4:06 PM

#

wooden condor I jsut mean in general, like it's an issue with Cisco too

I forget what problem we had, but the only solution Rockwell gave us was "We aren't fixing this, if you want the feature, go ahead and buy the actual Cisco version".

I understand that too an extent, but there's a difference in the level of 'work-around'. Using Weiss linear motors on allen bradley hardware, for instance, requires the addition of a filter (Capacitor and ferrite core) in the feedback cable. A simple and effective workaround, if a little bit annoying. Using an Allen Bradley linear motor in a vertical orientation on an Allen Bradley controller requires building an elaborate counterweight system because the motor can't physically hold up it's own weight for more than an hour without a drive thermal overload.

My brother has been playing games and talking to his friends, so I'd assume a dodgy cable wouldn't let him do that?

Tester doesn't work. I borrowed one from someone local last night where I saw his working. All the cables show them being completely fine with his one. I used my one again and showing the same thing. Going to see if I can get a replacement. Bought it over a year ago but only just used it. You never know, they might send me a replacement.

Im doing some research but im stuck as Solarflare was acquired by Xilinx and then Xilinx was acquired by AMD.

Basically im trying to find if any of these cards(excluding the BASE-T ones) support 10GBASE-LR Transceivers because I currently have a SFN5122f and it wont link to my switch using a LR 1310nm transceiver on both ends. The switch is not the issue as it detects the SFP module.
Any research you do would be greatly appreciated as I am completely stuck when it comes to finding documentation.

----------------------------

The drivers, utilities and applications contained in this package
support the following adapters:

-   Solarflare Onload server adapters:
    -   Solarstorm SFN4112F SFP+ Server Adapter
    -   //Solarstorm SFN5111T 10GBASE-T Server Adapter
    -   Solarstorm SFN5112F SFP+ Server Adapter
    -   //Solarstorm SFN5121T 10GBASE-T Server Adapter
    -   Solarstorm SFN5122F SFP+ Server Adapter
    -   Solarflare SFN5322F SFP+ Precision Time Synchronization Server
        Adapter
    -   Solarflare SFN6122F SFP+ Server Adapter
    -   Solarflare SFN6322F SFP+ Precision Time Synchronization Server
        Adapter

-   Solarflare Performant server adapters:
    -   //Solarstorm SFN5151T 10GBASE-T Server Adapter
    -   Solarstorm SFN5152F SFP+ Server Adapter
    -   //Solarstorm SFN5161T 10GBASE-T Server Adapter

When you port forward to the internet you only have 1 IP that you can host things on port 80 and 443. What you need is to either port forward other ports and manually specificy them (as well as exposing them in docker) OR (the better option) is to setup a reverse proxy. So myapp.example.com would go to one container and myapp_two.example.com would go to another

snow elk Sep 15, 2022, 1:00 PM

#

thick minnow kinda new on networking and docker

If using docker you need to specify the ports to forward using the argument -p <app_port>:<main_port> usually you d do just 80:80 or 443:443 and so on

#

first port is the listener IN the container itself and the second one is the port that's going to be open on your computer s NIC

#

Otherwise, just create a docker bridge network and connect the containers to that

#

They will then get their own IP addresses in your lan

Im trying to setup a port forward. I have everything correct on the interal side, that I know so far, and I am using a Linksys Smart Wifi router. Currently I am in WV, but my external IP says that I am in Chicago, IL, and I am trying to figure out why that is, becuase when I normally setup servers at home, it is simple Xfinity has port forwarding tools for games, and the external IP actually works. I confirmed already that I can join the server on the system that it is hosted on.

I contacted Linksys and ISP, but they were no help.

Anyone know how I possible could find the correct external IP if that one is wrong.

So I have a custom x86 router running openwrt, which is doing awesome and supports everything I need.
However, I am going to be moving soon and also in the unique position to pick up some dual port SFP+ PCIe cards for extremely cheap; wondering if it might be worth it to grab them?
Initial thought was to install one card in the router, another in my server, and then I could pick up a media converter if I needed one for connecting up my desktop switch or direct connecting my PC.

My big concern is idk if openwrt would support these cards, and I have minimal experience with fiber networking. I also wonder if the cards would support generic Cisco 10gb SFP+ modules?

tbh since you're running a media stack (it would seem) it might be worth using an OOTB setup like Swizzin, Saltbox, or Dockstarter 🙂

#

although they are targeted at Linux setups instead of Windows, the software itself that you are running seems to be better suited for that kind of 'headless' setup.

might also be worth looking at docker compose with SWAG or Nginx Proxy Manager, although I will say SWAG seems to be the easiest way for a beginner to get into reverse proxying. First I'd recommend moving all of your applications to docker, then serving everything internally (on the docker network) and accessing via reverse proxy from anywhere beyond there; of course with some kind of authentication enabled at every level of your setup, be that basic auth, authelia, or application auth itself (I'd go for basic auth if you're just starting out)

Mail Server Question:
Are some email usernames (maybe not the correct term) more likely to get sorted into SPAM than others?
Excluding the content, configuration etc. Just purely by having that email address.

E.g. is marketing@domain.com more likely to be sorted to spam than john.doe@domain.com?

#

Networking was the channel I thought was most likely to know the answer as I've seen mail server questions here before

tidal flower Sep 15, 2022, 10:26 PM

#

thick minnow the thing is I cant reach any container from my VPN

That’s likely because you haven’t forwarded the port to the host.

#

Although this is the perfect case for a reverse proxy, as others have said.

Not that I know of

Maybe?

Like like if it google in the name maybe they'll mark it as spam

But the primary methods are DKIM, rDNS, DMARC, and SPF checks

Also checking if the sending IP is on a blacklist

Does anyone know how to make it so you can get to the webui of your modem from hosts connected to the router?

Like assume that i have a host connected to a router. That router controls 192.168.0.X. The router connects to the modem which has an ip of 192.168.1.100 ... If i connect directly to the modem, i can get to the modem's webui, but if i connect to the router, i can't get to the modem's webui.

#

I can't change the modem's ip unfortunately. I also tried to change the router to control 192.168.X.Y instead of 192.168.0.X... but i still couldn't get to the router's webui

#

I also tried doing a static route in my router to help: ... but that didn't do it either

pure tendon Sep 16, 2022, 1:01 AM

#

On the router itself, its kind of funny: i can ssh in, but then i can't nc or ping the modem either. ... I can send an ARP though and get a reply

#

the ARP reply's mac matches the modems mac address so that seems ok

I'd figure out networking nerds here might be a good chance. I've come across some scam attempts on my relatives, it involves the scammer telling the user to run netstat on the computer. And the scammer would go on and say there's many hackers already logged onto the system.

Ofc I knew it was bogus, luckily relative was smart enough to doubt and asked me about it. I just told them it was BS. But I couldn't really give my relative a reason why it was bogus since I had no idea what the netstat command entails.

If I ran it on my Surface it'll look like this

I had this same situation if I read correctly. When I connected to modem I would get a public IP via DHCP. However I could still connect to the modem's webui via 192.168.100.1 I think it was

Maybe it's ISP forwarding back

No

snow elk Sep 16, 2022, 11:26 AM

Ye no

OH so dhcp is passed through the modem, from the ISP routers?

Aka his .1 in the subnet he s in

@hollow marlin I think i remember asking you how it works a while back.

Ok. So it's just a network terminal

What?

snow elk Sep 16, 2022, 11:30 AM

#

I don't see how accessing 192.168.100.1 would work if the routing is done already at the isp

peak cloak Sep 16, 2022, 11:30 AM

#

It's not

snow elk Sep 16, 2022, 11:31 AM

#

You said the modem doesn't do any routing/nating

peak cloak Sep 16, 2022, 11:31 AM

All traffic goes through modem. Modem would pickup any traffic destined for 192.168.100.1

#

snow elk You said the modem doesn't do any routing/nating

Yeah, it doesn't

snow elk Sep 16, 2022, 11:31 AM

#

Ohhe

#

Oh then he just has to write in a static route for 192.168.100.1 in his main router to go to his ISP node or first hop after the router

peak cloak Sep 16, 2022, 11:32 AM

#

Yeah that was my idea

snow elk Sep 16, 2022, 11:32 AM

#

Cuz it shouldn't by default route rfc1918 anyway

#

Yeah

I understood now

hollow marlin Sep 16, 2022, 12:10 PM

#

peak cloak <@462711605063450628> I think i remember asking you how it works a while back.

It varies greatly depending on the SP and their custom firmware slapped on the modem. It either handles it via proxy-arp, multiple interface addresses or simply PBR. There is a lot of software nonsense going on that I cannot give a good answer for.

hollow marlin Sep 16, 2022, 12:27 PM

#

snow elk Oh then he just has to write in a static route for 192.168.100.1 in his main rou...

That is already covered by the default route.

If their router's LAN subnet is say 192.168/16, then that would explain why it's unreachable behind the router because routing is not involved from the host perspective. A static route would not change anything.

pure tendon Sep 16, 2022, 3:04 PM

#

To be 100% clear about the network layout:

#

192.168.100.1 is the modem... there are no settings to change anything on it. It's a Motorola MB8611. 192.168.0.1 is the Router which all devices connect to. It's an Asus GT-AXE11000.

If i unplug the router from the modem and plug a computer directly into the modem, it can go to 192.168.100.1 to get to the modem's webui

#

The issue is that devices connected to the router (once its plugged back in like the diagram), devices can't get to the webui for the modem (192.168.100.1)

snow elk Sep 16, 2022, 3:12 PM

#

I don't understand. Does your 192.168.0.1 router get a public WAN IPv4 address or an rfc1918 private IPv4 address allocated by the modem (otherwise known as double Nat)

pure tendon Sep 16, 2022, 3:20 PM

#

it gets a public WAN IPv4 as far as i can tell

#

in the router settings it says 'WAN IP' then it lists my public IPv4

snow elk Sep 16, 2022, 3:36 PM

#

Sounds like a bridged modem

pure tendon Sep 16, 2022, 3:36 PM

#

I disabled all static routes, renewed my ip configuration... and now i can ping it but and tracert to the modem, but can't tcp/GET it

nope, the modem only has one ethernet port

#

(and that normally goes into the router)

sudden kayak Sep 16, 2022, 3:37 PM

I mean you really shouldn't need to access the modem configuration in normal usage

snow elk Sep 16, 2022, 3:38 PM

Well this means the routes are good for upstreaming to that but are you sure the router you have SNATS to itself instead of the local lan ip?

pure tendon Sep 16, 2022, 3:38 PM

agreed... though i have a particular case where i'm trying to get something from the modem webui

its not supposed to. According to the manual/webpage it should still be accessible via a router

dunno if that's coming from the modem w/ some kind of ARP manipulation or if the router set that up for convenience

i can ask around internally but idk i think it's probably hard to nail anything down because it depends on the modem vendor and all bets are off for COAM equipment

Do you want to use an existing router manufactured by a known brand or from scratch?

Cheapest way is an intel NUC or something that has two interfaces

Moving this from the public-chat
I recently revamped my old ASUS desktop and turned it into a NAS using TrueNAS Scale. It seems to be running okay and I have SMB sharing set up. Yesterday I installed a couple 8TB Seagate IronWolfs to have some actual storage (Rather than the 32GB thumb drive I was using to test) and now I'm in the process of transferring all of my data from a 4TB External drive to my server. The problem is that my transfer speeds are painfully slow, barely hitting 12MB/s. Is this normal or is there something that may be wrong that could increase my transfer speed?

#

Oh heckin' yeah, disabled WiFi and hitting almost 100MB/s now. Thanks @waxen saddle!!

Depending on the os, it can be really easy or kinda painful. Depending on whether you want your pc to nat or not, you need to bridge the 2 network interfaces or masquerade the incoming requests. In linux Bridging is really easy, in windows i‘ve never done it. I know it‘s fairely easy to use the „share network“ function in the adapter properties, but i don‘t have a windows machine on hand right now to check

I have made it so that my main router is wirelessly bridged to this old router, so I can also access it's interface and everything. Problem is I need to forward that ftp server to the web, and I've tried doing it on my main router through the internal ip of the router that is hosting the ftp and port forwarding that, to no avail.

I wouldn't trust the old router's ftp server on the internet - who knows how old or vulnerable the software is?

#

Plus FTP in general kinda sucks on that front, being unencrypted and all

#

I agree with using VPN, or add your files to cloud storage - or at least get a modern build of openWRT on the router so you know what you're dealing with and idk... SFTP and cert-based auth?

If it's too old for up-to-date openWRT, it's too old to be exposed to the internet

cinder plank what does this mean for a device that i connect via the dmz?

Everything the firewall does not explicitly block will go to that host

pseudo blade Sep 18, 2022, 9:00 PM

#

Using a DMZ is functionally equivalent to forwarding all ports not already forwarded to something else.

cinder plank Sep 18, 2022, 9:00 PM

#

So the local (local to the dmz) ports become public ports?

pseudo blade Sep 18, 2022, 9:01 PM

Kinda?

#

For your use case, a DMZ is less recommended than forwarding explicitly the ports you need.

#

I assume you do not have complete control over the device's firewall and operating system.

#

If you put it in a DMZ, you are likely to expose services you don't intend to expose, which poses a security risk.

So the putting a device in DMZ doesn't necessarily stop that device from seeing other device on the lan? I thought that was the purpose of a DMZ?

waxen saddle Sep 18, 2022, 11:43 PM

#

Depends on how the router handles it. I’ve seen some that actually isolate the DMZ from everything else, and others that only let you specify an internal IP on the local LAN and do no isolation at all.

#

Run a test and see how yours handles it.

cinder plank Sep 18, 2022, 11:48 PM

#

okay. is the test simply, can i / can't i ping LAN devices form the selected dmz device?

hi, im trying to get wireguard pivpn setup. i seem to be able to connect and use the vpn via local network, but traffic isnt going through on non local network. the server is recieving udp packets, but the client doesnt seem to receive from the server. i checked port forwards and everything seems fine though?

ember basin Sep 19, 2022, 3:26 AM

#

it seems to transfer enough data to get the "last seen" on wireguard updated

#

but does not succeed handshake?

There a way to purposefully sabotage a cable internet connection to make it appear slow to convince someone to switch to fiber internet?

I don’t think we can answer that type of question here.

I don't mean "throwing the router down" or anything criminal. I mean is there something in the router admin settings that I can tweak.

Like the slowest lane of traffic

Yes it's possible but depending on circumstances there is definitely legal liability.

If you have to artificially degrade a circuit for it to become a problem, then there is no problem if whoever is fine with their current connection.

pseudo blade Sep 19, 2022, 4:14 AM

I am uncertain about the legal implications (quite possibly if you're trying to impact the person paying for the connection) but for me there's moral ones also.

couldn't you say you're okay with paying more to upgrade

neat whale Sep 19, 2022, 4:17 AM

They don't agree. They think its fine as is.

pseudo blade Sep 19, 2022, 4:17 AM

Pay for it yourself then.

#

If it costs too much to do so... oh well guess you don't need it that badly then

#

Pay for the fiber, tell them you won't pay half for the cable, offer to split the fiber

#

Be prepared to pay the full price if they say no

unborn sluice Sep 19, 2022, 4:18 AM

yea, if you're not a kid. then talk to them like adults and convince them

indeed my point, cover the upgrade

The main beef is the installation costs.

waxen saddle Sep 19, 2022, 4:25 AM

Does spectrum OWN the cable lines in your area?

neat whale Sep 19, 2022, 4:25 AM

#

I think so

waxen saddle Sep 19, 2022, 4:27 AM

#

It can make a huge difference if they do or don’t. Comcast owns all the cable lines in my area. Anyone other than Comcast can provide service, but not near the speed and reliability that Comcast does. They literally are in business fueled by hatred for Comcast.

Yea I am just referring to malicious intent scenarios and I agree there is a much bigger moral issue as well.
However in this case this could be valid in a small claims court. A verbal agreement to split a bill on a shared service does not mean you can purposely degrade their service without their agreement. Especially out a spite because the involved parties do not want to pay more

The throughput of this link was 3mbps. In 2019.

#

Nowadays I'm getting ~150mbps via mobile broadband or 70mbps via vdsl which is vastly preferable

I know what DSL is

pseudo blade Sep 19, 2022, 4:33 AM

It's that but faster.

#

And asymmetric so faster downloads than uploads.

#

It still sucks compared to nearly any other technology

#

...Unless your cable networks are really long and oversubscribed

hollow marlin Sep 19, 2022, 4:38 AM

#

Having been an engineer responsible for xDSL, it sucks just as much in regards to troubleshooting

pseudo blade Sep 19, 2022, 4:38 AM

#

lol

#

Trust me I know

#

I still can't believe my country's government payed many billions of dollars for the incumbent ISP's copper networks so they could use them for VDSL rather than build fiber

#

As the faster solution in the mid 2010s because ADSL sucked, mind you

#

Threw out a full fiber build to save money, to spend billions on a ancient telephone network for VDSL

hollow marlin Sep 19, 2022, 4:42 AM

#

Knowing the cost, it is much cheaper in the short term. Fiber/hardware is cheap. Labor, not so much

pseudo blade Sep 19, 2022, 4:42 AM

#

Nothing's cheap if you have to dig it up soon after to replace it

#

VDSL had no room to grow and with runs up to 1km it couldn't hit 25mbps often

hollow marlin Sep 19, 2022, 4:43 AM

#

Thats why I mentioned short term. They never include the future upgrade paths, but more importantly, how expensive it is to maintain copper
