#

hard to say what to do but really you want to cut back on complexity if you can't determine what's causing you problems

strong tusk Feb 7, 2020, 6:06 PM

#

So, have you ever used the controller itself?

vapid dune Feb 7, 2020, 6:06 PM

#

yes

#

I've used local ones, remote ones, and cloud hosted ones

strong tusk Feb 7, 2020, 6:07 PM

#

The ip it list for the device in the unifi controller is it a random generated one or the one for the device itself?

vapid dune Feb 7, 2020, 6:07 PM

#

the controller sees devices?

#

the IP of the device is generally handed out by the DHCP server (usually the router)

#

do they already have other unifi stuff?

strong tusk Feb 7, 2020, 6:08 PM

#

The controller sw sees the AP and the switch, and lists ips under them. However, they don't match the default ones that unifi told us to use...

#

so is that one that the router is sending out?

vapid dune Feb 7, 2020, 6:08 PM

#

are you just installing an extra controller on their network? lmao

#

default IP? o.O

#

what default ip?

strong tusk Feb 7, 2020, 6:10 PM

#

Well, we have fios and their hybrid router/modem thing. It's in the basement, and from the basement is a long ethernet cable going into the switch 8 60w. Then through a POE cable out of that thing's one POE port goes into the AP.

vapid dune Feb 7, 2020, 6:11 PM

#

I'd start with getting the switch working first

strong tusk Feb 7, 2020, 6:11 PM

#

well, apparently there's default IP address for both the switch and the AP according to the company.

vapid dune Feb 7, 2020, 6:11 PM

#

huh?

#

I'd plug the computer with the controller into the router, then the switch into the router

#

adopt the switch. make sure the switch is running nicely. then plug the computer into the switch. see if that's running as you'd expect. then plug the ap into the switch and adopt

#

or the ap into the router really

#

I mean I assume the switch should just run without adoption even (but I don't own one so I haven't tried that part)

strong tusk Feb 7, 2020, 6:13 PM

#

So, there needs to be a physical connection to the switch itself to a computer? You can't just have one on the same network? Cuz if so then I'm going to slap my brother in law.

vapid dune Feb 7, 2020, 6:13 PM

#

huh? it can just be on the same network

#

I'm just indicating what you could do to test that things are working. just do it as simply and piece by piece

strong tusk Feb 7, 2020, 6:14 PM

#

So, he's trying to tell me to do it on a computer that's not on the same switch just on the same network.

vapid dune Feb 7, 2020, 6:14 PM

#

you can do it that way too but clearly things aren't working lmao

#

just eliminate complexity if you can't figure out what's causing problems o.o

strong tusk Feb 7, 2020, 6:14 PM

#

I mean I can go into the laundry room where the switch is and hook my laptop up to it directly.

vapid dune Feb 7, 2020, 6:15 PM

#

maybe try that and see if there's even network connectivity

#

all the devices should be pingable and you should be able to ssh into them

#

assuming that you want it working and not firewalled/routed into oblivion of course

strong tusk Feb 7, 2020, 6:18 PM

#

Well, I think the two problems we're having is the screwed up way my brother in law altered the rest of the network plus the fact that other than my second switch and the hybrid thing in the basement there's nothing directly connected to the switch or AP

little schooner Feb 7, 2020, 7:06 PM

#

@strong tusk perhaps your brother in Law should of created documentation of it

#

How everything is connected and some ip list

vapid dune Feb 7, 2020, 7:12 PM

#

and if there's any vlans and what not going on

#

or black/white listing

#

really though if it's home use without someone who knows how to manage it around, I'd suggest making the network topology as simple as possible xD

strong tusk Feb 7, 2020, 7:18 PM

#

well we managed to adopt the AP and not the switch, but honestly I don't care right now as I had to fix some settings in the AP, not the switch. <.<

warm bramble Feb 7, 2020, 9:39 PM

#

Why do I have 664 ping to google.com (through cmd) 20 download and 80 upload (no clue why my download is way less than upload)

craggy parcel Feb 7, 2020, 9:40 PM

#

@warm bramble Because your connection is routed through a satellite?

warm bramble Feb 7, 2020, 9:40 PM

#

?

craggy parcel Feb 7, 2020, 9:41 PM

#

If there's a satellite link in the mix from you to google, you will have ping times in that range.

warm bramble Feb 7, 2020, 9:41 PM

#

Oh

#

k

craggy parcel Feb 7, 2020, 9:43 PM

#

It could also be any of the other 100 explanations for high ping times...

#

Also bandwidth and ping times has absolutely NOTHING to do with each other. You can have a 128 kbit connection, with just a few ms ping, and a 10 Gbit connection with high ping. It depends on a LOT of factors.

#

A satellite link, is most likely not the reason, unless you are using an actual satellite connection yourself.

Hey guys quick question does anyone know anything about configuring a vpn with dd-wrt?

thorny vector Feb 8, 2020, 12:15 AM

#

What about it?

little schooner Feb 8, 2020, 12:34 AM

#

I'm having some trouble finding a good callback service

#

I want a number to call me back and then let me type in the number it should dial and connect me

fresh copper Feb 8, 2020, 1:52 PM

#

Some telephone providers have a special number you can call which calls you back as soon as you hang up but I have not heard of any 3d party services

little schooner Feb 8, 2020, 5:37 PM

#

@fresh copper aww

#

So my other option is to simply get a second phone and root it

craggy parcel Feb 8, 2020, 6:07 PM

#

@little schooner The normal way those services work, is you get a card with a code, then a toll free number, that you call. When connected you enter the code from the card, then the number you want to call. However, I don't see what problem you are trying to solve.

waxen scroll Feb 8, 2020, 6:49 PM

#

@little schooner i miss my personal conference bridge

little schooner Feb 8, 2020, 8:01 PM

#

@craggy parcel call recording

#

It doesn't work on android 9

#

It used to work great on android 8

#

And android 10 is further restricted

craggy parcel Feb 8, 2020, 8:34 PM

#

Lots of services using the conference calling feature from your telco, exists.

little schooner Feb 8, 2020, 8:36 PM

#

@craggy parcel like sprint?

#

What does sprint have that works like that

#

Like add call? The problem with that is, once I add the next line, my touchtone pad stops working

craggy parcel Feb 8, 2020, 8:47 PM

#

They probably don't have the actual call recording features, but a lot of 3rd parties does provide a recording feature, where you dial a number, that records the conversation. You just add the recording service to the call you wish to record.

#

Basically every call recording app for iPhones, work more or less in this way.

little schooner Feb 9, 2020, 12:57 AM

#

@craggy parcel hmmm thanks for pointing that out

#

I guess I will give Rev call recorder a try on iphone, now knowing this

little schooner Feb 9, 2020, 7:22 AM

#

After lots and lots of troubleshooting, I finally got the lab with hyperv servers in a cluster, configured with constrained delegation and enabled high availability of two VMs.

Now it should be as simple as turning off one of the hosts for the live migration to happen automatically to the next available hyper V host

#

The performance of saving virtual machines to a network share is really slow

thorny vector Feb 9, 2020, 8:19 AM

#

@little schooner how are you liking hyper-v? I've never really strayed from the VMWare path, although I've thought about trying to set up a server 2016 instance to try it with.

little schooner Feb 9, 2020, 3:06 PM

#

@thorny vector it's great until you need to manage it remotely. Something about setting up constrained delegation which was driving me crazy when it wasn't working.

Other than that, Hyper V runs fast and good. The biggest advantage of using it is that there is no licensing for using hypervisor and automated virtual machine activation for Windows Server licenses.

I recommend using 2019 because 2016 has a real problem with applyinf updates really... Really.... Slowly.

#

I'm fighting a new problem with live migration now. I know it's permission problem or a step I missed.

#

No issues if you are just using it standalone on a single server

waxen scroll Feb 9, 2020, 3:26 PM

#

ping

little schooner Feb 9, 2020, 3:58 PM

#

@waxen scroll You can tell I am fairly new to cluster stuff

#

I really want to put it into the lab badly, because of that last disk failure we had

#

@waxen scroll that day also had vmware workstation licenses expire

#

so the teacher had that and the students telling them nothing worked during lecture. it must of been painful

thorny vector Feb 9, 2020, 4:26 PM

#

I don't think I could use any other live migration other than Vmotion. It's pure magic

waxen scroll Feb 9, 2020, 4:30 PM

#

@little schooner how does school let that happen

#

most of these licenses are deep discount

little schooner Feb 9, 2020, 4:52 PM

#

@waxen scroll Dunno. I guess they forgot to renew or pay

#

Professor did say he was going to pay with his own money

#

but backed out of that

waxen scroll Feb 9, 2020, 4:54 PM

#

i would too

#

sometimes i do pay but i dont let the company use it directly

#

like... they give everyone shit monitors, so i buy my own

#

or... i want this screenshot / editing app, so i buy my own but use it more than just at work

#

VIRL... same thing

#

current job is so cheap that for monitors you get whatever. they'll be mismatched, sometimes not wide screen

#

im known as "that guy with the ASUS monitors" for people who dont know me. lmao

little schooner Feb 9, 2020, 4:58 PM

#

heh I would totally do the same thing. I dont like being given the bottom of the barrel stuff. Our lab started out exactly like that anyway

#

also, he wants Hyper-V because he doesn't want to deal with the license expiry stuff but

#

I mean a calendar reminder would be a good option too

waxen scroll Feb 9, 2020, 4:59 PM

#

thankfully they at least give us copies of secureCRT even if its outdated by 3 years

#

CRT doesnt change that much anyway

little schooner Feb 9, 2020, 4:59 PM

#

yeah. its pretty great

#

I actually use Royal TS myself now

#

its served me well for holding like 100 connections of rdp, sftp and ssh

#

but not as fast, since its based on .net

#

but its very functional

waxen scroll Feb 9, 2020, 5:00 PM

#

if i need 100 connections i just script it

little schooner Feb 9, 2020, 5:01 PM

#

oh the connections are there just for me to quickly get an idea of how many of them have services enabled

#

i dont connect to all of them but they are in a folder that tells me "okay, these pcs have these remote in capabilities enabled"

waxen scroll Feb 9, 2020, 5:02 PM

#

i stopped working on multithreading, i have to pick that back up so the next time i need 100, its done in 5min versus 40min

little schooner Feb 9, 2020, 5:02 PM

#

Thats a dramatic reduction in task time

waxen scroll Feb 9, 2020, 5:02 PM

#

yep

#

i dont know why, but getting python to ssh things is slow

#

so while it waits to send commands i can begin a new connection somewhere else

#

i have to build protection in some how too so that it knows if my login is valid

#

i cant blast 100 devices with a bad login or i will get locked out

little schooner Feb 9, 2020, 5:17 PM

#

yeah, need to implement some checks there.

#

also I just finally figured out why my hyper-v cluster was having issues with live migration

#

it was the dang firewall in action on the file server

#

🤯 !!

#

Wasted so much time and no answers online really led me here to this conclusion of firewall

#

doesn't make any sense why it works this way

#

📎 unknown.png

#

@waxen scroll Words cannot describe my frustration right now. Windows randomly decided to change its network profile to "Public" and caused live migration to break again. It didn't even let me know it did that when I made port exceptions just for Live Migration traffic

#

Ugh windows keeps wasting my time lol

clear igloo Feb 9, 2020, 5:27 PM

#

Surprise! 😄

waxen scroll Feb 9, 2020, 5:28 PM

#

never had that happen except maybe if you add it to a domain

little schooner Feb 9, 2020, 5:29 PM

#

It is domain joined but for some reason, network profile isn't switching to DomainAuthenticated

craggy parcel Feb 9, 2020, 5:48 PM

#

@little schooner In my experience, the domain profile will only be applied if the domain controller is accessible through that interface. So if DNS was out of service temporarily, or the machine did not manage to login to the domain for any reason, even though the user does manage to login to the domain without problems. 😉

little schooner Feb 9, 2020, 7:26 PM

#

@craggy parcel yeah. Well it is accessible through that interface (and now functioning okay) but is still stuck in Public Profile. I am not sure if it was the fact that I had to switch out eth0 and eth1 NICs to be VMXnet3 ones when it was originally Intel NICs. I joined the domain using the Intel ones and that's when I noticed the network profile problem

#

I think it still has old references in device manager of the older NICs being configured with IP settings and remembers them

#

But that's just a theory

#

I tested Hyper-V live migration and works as it should, but it is not fault-tolerant

waxen scroll Feb 9, 2020, 7:33 PM

#

guess you'll be switching to vmware

little schooner Feb 9, 2020, 7:34 PM

#

Yeah...

waxen scroll Feb 9, 2020, 7:34 PM

#

or get rid of all of it and switch to azure

little schooner Feb 9, 2020, 7:34 PM

#

Would be faster

#

@waxen scroll if I understand this correctly, fault-resistant means that multiple servers can take ownership of a role (like, serving files from a SAN share) if one of the servers currently hosting it goes offline. It would fail over to another server and no downtime is observed

However, if the SAN were to go offline, the cluster of servers doesn't do anything helpful, since the file storage would still be offline

#

I got that right so far?

waxen scroll Feb 9, 2020, 7:39 PM

#

i dont speak hyper-v, however in general terms yes

little schooner Feb 9, 2020, 7:41 PM

#

Okay, and then how I understand fault-tolerance in a general sense, I can say that I have two SANs that have duplicate data and a cluster of servers serving files from the SAN share. If one SAN goes down, fault tolerance comes in by the 2nd SAN taking over what 1st SAN was doing: storing shared files.

#

That I guess is fault tolerance?

waxen scroll Feb 9, 2020, 7:51 PM

#

so in terms of SAN im not an expert. its difficult for me to assign terms to different types of SAN

#

a SAN unit has multiple supervisors/cards/etc

#

then you have the option to maybe replicate it to another SAN

#

but i cant speak to if you can active/active that way

#

if its not active/active then you might lose function until the other side can take over

#

ive racked and cabled SAN units but networked storage is one area i have 0 experience with

#

im kind of thinking that people dont actually replicate SAN LUNs

#

its possible they might make the LUN redundant on the same chassis with different sets of disks

#

think of how much pain that is to replicate a LUN to another datacenter as its being used

#

how much bandwidth is required

#

when i managed esxi in a lab which was set up for me already it connected to one SAN and each LUN was presented as a different hardware disk to provision VM disks on

#

current job is that way too... i dont have access to production vmware though

little schooner Feb 10, 2020, 12:44 AM

#

@waxen scroll well, I was just using it as example. Maybe I should of said, a file share was being replicated and both servers can serve the files, but if one of them goes down, the other will continue to serve the files on the share

#

Not necessarily with SAN, more like smb that's duplicated with dfs

severe wigeon Feb 10, 2020, 3:06 AM

#

Lets see if you guys can help what xfinity cant. Put my SBG6900-AC in bridge mode, connected pfsense box to port 1, tried my archer c7, nothing

#

Because these "techs" are half ignorant

hollow marlin Feb 10, 2020, 3:17 AM

#

@severe wigeon Well what exactly is the problem, is your pfsense box actually able to reach out

severe wigeon Feb 10, 2020, 3:23 AM

#

Im not getting my ip from their dhcp server

hollow marlin Feb 10, 2020, 3:25 AM

#

Check the interface stats on the pfsense box and see if you are actually getting, hell, sending request

severe wigeon Feb 10, 2020, 3:26 AM

#

Well pfsense was just to test, im trying on my archer c7 because im getting rid of pfsense, but it does request, i attempt to renew, nothing

#

Called Arris they said my config is right, its literally just xfinity

#

Ive even plugged my pc in to port 1 tried renewing nothing

hollow marlin Feb 10, 2020, 3:30 AM

#

Its probably just a lease limit. They dont let multiple leases exist on a single connection and if you changed to bridged, plugged in pfsense you already chewed through 2 leases.

severe wigeon Feb 10, 2020, 3:30 AM

#

Hmm

#

It should work though? Its worked on ATT and mediacom

hollow marlin Feb 10, 2020, 3:31 AM

#

You'll have to call to clear them or wait it out. But if you throw your modem back in router it should get its lease, at least should point out if that is the issue

severe wigeon Feb 10, 2020, 3:32 AM

#

They refuse to believe its their side

hollow marlin Feb 10, 2020, 3:33 AM

#

Just tell them you pulled multiple leases. They follow scripts and search via topics

#

It might point them in the right direction

severe wigeon Feb 10, 2020, 3:33 AM

#

Told them

#

Finally got to the "floor supervisor"

#

See how this goes

#

🤞

#

Whole lot of nothing... "Advanced Technical Support" doesn't know what a dhcp lease is.

primal ice Feb 10, 2020, 4:10 AM

#

DOCSIS needs reset stupid cable modems.

little schooner Feb 10, 2020, 4:11 AM

#

I have Comcast and how I managed to finally get dhcp lease was a forced renew or reset the cable modem

severe wigeon Feb 10, 2020, 4:11 AM

#

I killed its power for 5 minutes

little schooner Feb 10, 2020, 4:11 AM

#

And if that doesn't work, wait it out if they set some kind of time limit

primal ice Feb 10, 2020, 4:11 AM

#

its normally a 2 hour lease

severe wigeon Feb 10, 2020, 4:12 AM

#

Guess ill head to the gym then

severe wigeon Feb 10, 2020, 4:34 AM

#

Whatever they did, i cant login to my modem anymore

#

Ssh gone, gui gone

#

Can ping it though

#

Fixed it

severe wigeon Feb 10, 2020, 5:24 AM

#

Yeah... nothing

little schooner Feb 10, 2020, 8:11 PM

#

@severe wigeon did you try another modem?

severe wigeon Feb 10, 2020, 11:07 PM

#

Dont have another

#

And yeah i considered it could be modme

#

Ill reset it entirely when I get back and try again

primal ice Feb 10, 2020, 11:41 PM

#

or uhm get a cable pcie card in your pfsense box and get rid of the modem.

severe wigeon Feb 10, 2020, 11:58 PM

#

Thats possible?

primal ice Feb 11, 2020, 12:14 AM

#

nah guess they do not make a pcie cable modem card anymore. can still find old pci ones though :p . stuck with an external modem for cable. (been looking)

primal ice Feb 11, 2020, 12:34 AM

cisco makes a module one for their router interface go figure. but not seeing any kind of converter for it.

waxen scroll Feb 11, 2020, 12:47 AM

@clear igloo does the network person blame the server people or do the server people blame the network person?

I've been asked to add 214 firewall rules to a core router...

#

All of them blocking individual ports on individual IPs.

severe wigeon Feb 11, 2020, 5:34 AM

hollow marlin Feb 11, 2020, 5:34 AM

#

You should be trying it without bridging to see if the modem even comes up

severe wigeon Feb 11, 2020, 5:35 AM

#

The modem has full connection, and to answer, I have actually tried before, and the router gets a private ip from the modem

#

So it CAN get an ip

hollow marlin Feb 11, 2020, 5:36 AM

#

Im talking about the modem getting an IP from the WAN

severe wigeon Feb 11, 2020, 5:37 AM

#

Modem never gets an ip in bridge mode

ornate jungle Feb 11, 2020, 5:37 AM

#

If the modem is bridged, it should not get an IP on its' own, since that IP will be given to the first device connected. (or multiple devices, if there's a switch involved and you have more than 1 IP provisioned on your account.)

severe wigeon Feb 11, 2020, 5:37 AM

#

it's not suppose to ^

hollow marlin Feb 11, 2020, 5:38 AM

#

No crap, not talking about getting an IP in bridge

severe wigeon Feb 11, 2020, 5:38 AM

#

and It does release my dhcp lease when I go into bridge mode

hollow marlin Feb 11, 2020, 5:40 AM

#

Take it out of bridged, login to it and see if its getting a WAN IP

severe wigeon Feb 11, 2020, 5:40 AM

#

It does

#

The modem works fine out of bridge mode

hollow marlin Feb 11, 2020, 5:40 AM

#

Ok, thats essentially what I was asking

severe wigeon Feb 11, 2020, 5:40 AM

#

Horrible wording

#

spooled up a pfsense vm giving it its own nic from port 1 of modem, it doesn't get an ip

hollow marlin Feb 11, 2020, 5:54 AM

#

for shits an giggles, can you do a wireshark

severe wigeon Feb 11, 2020, 5:55 AM

#

why not

#

wait

#

that wont work

hollow marlin Feb 11, 2020, 5:57 AM

#

If you spun up a VM, you can capture the NIC from the host

primal ice Feb 11, 2020, 5:58 AM

#

out of curiosity did you disable the wireless portion of the modem? if not check your wireless devices for a public IP.

severe wigeon Feb 11, 2020, 5:59 AM

#

yeah wireless is off

and you are using port one as the pass through?

severe wigeon Feb 11, 2020, 6:00 AM

#

wait wtf

#

my pc got it

#

so bridge is running fine

#

that's progress

#

wait... it just hit top of hour

#

yeah its working in bridge mode now

#

to my pc at least

primal ice Feb 11, 2020, 6:02 AM

#

you can only have one device connected to it in bridged mode. the one you want to get the wan ip on.

severe wigeon Feb 11, 2020, 6:02 AM

#

Yeah ik

#

Oh yeah lol

#

Yeah releasing and renewing works fine on windows

#

its a like 50 minute lease

hollow marlin Feb 11, 2020, 6:05 AM

#

Is that about how long since you had your modem not bridged?

severe wigeon Feb 11, 2020, 6:05 AM

#

Its bridged still

#

My pc got the public ip

#

Because i plugged it i to port 1

#

So modem is fine

hollow marlin Feb 11, 2020, 6:06 AM

#

Im just trying to point out that I still think this was a multiple DHCP request problem

severe wigeon Feb 11, 2020, 6:06 AM

Funno

#

hollow marlin Feb 11, 2020, 6:07 AM

#

Release it, plug it into pfsense, reboot modem and then reboot pfsense

severe wigeon Feb 11, 2020, 6:07 AM

#

I stopped pfsense

#

Its not meant to be what runs anyways

hollow marlin Feb 11, 2020, 6:08 AM

#

Well try the above steps with your archer

severe wigeon Feb 11, 2020, 6:08 AM

#

Just sent reboot to it

#

This is why im glad my tablet has data

#

It rebooted, no ip yet

#

Ill give it a minute

hollow marlin Feb 11, 2020, 6:10 AM

#

Rebooted archer as well?

severe wigeon Feb 11, 2020, 6:10 AM

#

No, the modem is running fine

#

My macbook can get public, my pc can get it

#

Seems openwrt just isnt happy

hollow marlin Feb 11, 2020, 6:10 AM

#

I thought you said you were running your archer C7 after the modem

severe wigeon Feb 11, 2020, 6:10 AM

#

I am

#

Pfsense vm gets public

#

Its just the c7

hollow marlin Feb 11, 2020, 6:12 AM

#

You should reboot it as well. Consumer devices are turds when it comes actually doing its job. Tends to timeout after initial discover

primal ice Feb 11, 2020, 6:17 AM

#

could be a bad openwrt flash. try an older version.

#

had a few of those with my buffalo ac1750hd which I just turned into an AP and started running a pfsense box that I built myself from an old i7-950 x58 system.

severe wigeon Feb 11, 2020, 7:08 AM

#

So I found my issue

#

I just cloned the mac of my pc

#

instantly fucking connected

#

-_-

primal ice Feb 11, 2020, 7:21 AM

#

bandaid fix - still think there might be a problem with the openwrt. but if it works it works.

severe wigeon Feb 11, 2020, 7:26 AM

#

I went in the pfsense vm and it was using my nic mac

#

odd with my macbook though

#

¯_(ツ)_/¯

#

Now for ddns

#

Works

little schooner Feb 11, 2020, 5:14 PM

#

Well, if I remember correctly, in my case with Comcast, they could only lease out an IP to 1-2 Mac addresses. I remember calling to activate my modem but now they use an online wizard to process this.

#

But I also noticed that my chromebook was also able to get a lease somehow, so maybe my limit is much higher than 1-2

elder stag Feb 11, 2020, 5:59 PM

hello,

We have been having problems with our network

the ip adresses always giving problems now - cirtian websites will not load because there is a problem with the DNS server address or sub-net configuration

this is effecting all of our computers on the network.
the only way we have fixed some of them is by giving the computers a fixed ip address instead of dynamic

what is causing this or how do you fix it?

there are no other DNS or DHP services going on besides one that i am aware of. maybe i need to check that but not sure how to do that.

also, could have something been injected into the network and its just taking time to flush out the bad addresses?

thanks

elder stag Feb 11, 2020, 11:42 PM

fervent brook Feb 12, 2020, 4:31 AM

#

Utah, if you end up on a different network, you pretty much have to just set a static address in the right network

elder stag Feb 12, 2020, 4:34 AM

#

I dont remember - it was on dynamic ip before it was changed to static

#

Utah, if you end up on a different network, you pretty much have to just set a static address in the right network
@fervent brook are you refereeing to the computer? or the modem device that assigns the ip addresses?

fervent brook Feb 12, 2020, 4:44 AM

#

I mean, if your isp tells you which ip to use, you can set a static ip on your modern

#

I'd ask why your modern is setting your ip addresses, but I know why...nobody should ever use those, but you can't really help it since it was probably your parents decision

primal ice Feb 12, 2020, 4:54 AM

#

@elder stag check your router settings seems like each port is a subnet. which is what pfsense does to a 1 port, 2 port, or 4 port pcie cards. you can bridge ports so they are the same subnet.

thick minnow Feb 13, 2020, 5:12 PM

Every night I get packet loss like this and download speed gets reduced to 4 - 6 Mbps, whereas upload remains 60 Mbps constant. I don't use to get this before when I purchased my connection since 2016 and my Internet was stable asf. My ISP haven't been able to fix it and this problem is occurring since 29th December, 2019.

📎 unknown.png

#

The IP is default gateway.

#

Can anyone probably say what might be the issue. My ISP uses ONU and distribute the connection via Netgear Switch to other home users, they have replaced the Switch to check whether it was that causing the problem and it isn't, even after replacing that Netgear switch the problem still persists.

My friend used to get similar packet loss problem on his side on a different ISP, his ISP replaced the Load Balancer and it got solved.

#

I have talked to same users of ISP in different city and they say they aren't facing any problems like I'm facing.

#

If anyone works in ISP here, would love to hear something back from someone GWmythicalFeelsSadMan

@little schooner whats the order of operations to check a bad network connection?

#

@rocky badge whats the order of operations to check a bad network connection?

#

you work at an isp and a customer calls in asking for engineering to blame the load balancer. you have access to smart switches, ONTs, whatever. whats the order of operations when the user blames the load balancer

#

🤔

hollow marlin Feb 14, 2020, 1:53 AM

#

The cold weather is slowing the load balancer down thats why its slowing down in the evening. The heater must have broke in the previously replaced unit.

#

Should immediately escalate to engineering to cuddle the unit ❤️

waxen scroll Feb 14, 2020, 1:56 AM

#

yes, that can happen. thats why newer load balancers actually have ASICs which are engineered to compute useless calculations with their spare resources whilst the temp sensor of the unit reports under 50 F. Its way more efficient when warmer. It uses an internal ethernet ring to quickly kill useless calculations once customer demand spikes. This eliminates tail drops.

#

i think The_Saviours ISP must be on the old load balancer and having many tail drops due to cold

#

i think its pathetic that these ISPs who make insane profits off bandwidth cant even use spray foam in their outdoor cabinets

#

you can get a can of "the good stuff" from home depot for like $5/ea

little schooner Feb 14, 2020, 2:59 AM

@waxen scroll
By bad, does that also mean no connection?

Check physical cable at station
1.1 check station nic
1.2 check if nic is disabled in software or hardware
Check switch to see if it lost power
Check port on switch that leads to station to see if it has activity light
Check if switchport triggered port security

It was worth a try.

But for diagnosing network problems, Wireshark is a good starting point

waxen scroll Feb 14, 2020, 3:42 AM

#

No, I mean ping loss at second hop

#

The home router being hop 1

little schooner Feb 14, 2020, 4:16 AM

#

That happened at the college. What it ended up being is a filter of some kind blocked access after we used the port for about a month. They didn't want it to be used because it was on the production network that isn't in Prof's control. Then, we tried using a laptop and it brought up a broken https web filter page that was empty. But we were being redirected. At that point, then, all ping hops ceased to work for us and it was totally shut down

#

@waxen scroll well maybe the router is busy or firewall on it

thick minnow Feb 14, 2020, 4:26 AM

#

So it might be the the Load Balancer which is getting cold 🤔

#

During day time I don't get packet loss however download speed remains between 40 Mbps - 57 Mbps.

#

Instead of constant 60 Mbps and at night it crawls to 4 Mbps.

little schooner Feb 14, 2020, 4:09 PM

#

If it happens at night consistently, totally sounds like a configuration thing. The temperature at night doesn't always dramatically drop from day time Temps

#

Even if that configuration is with hvac systems or other policy and electronics stuff

Hi guys, I have a standard Virgin Media hub 3 (came from isp) (https://www.expertreviews.co.uk/wireless-routers/1407886/virgin-media-hub-3-review) on my ground floor. On the second floor is my pc which requires a wired connection. atm, I am using https://www.netgear.com/support/product/EX2700.aspx on my floor and taking a wire to my pc but if I ever game or download something, I need to set my fan on it or it overheats and crashes. I can't get a direct wire to the pc from the router and I can't move the pc to the ground floor. Any better solutions to this, preferably ones that aren't too expensive, are welcome. Thanks 🙂

Here's a question
We've got a somewhat shitty NVR for our CCTV system. Today I've noticed that it actually has port 554 open (rtsp) meaning I can get video streams out of it in a neater way than the horrible activex webUI.
How can I go about exposing this rtsp stream to the internet when you consider I'm behind a CG NAT and can't simply forward the port

Generally for SSH-ing into my network I rely on services like ngrok to form a tunnel to my machine, but since I clearly cannot run ngrok on the NVR, what do I do?
I've tried running ssh -N user@<myLocalMachine> -L 1337:<NVRIp>:554 but that did not seem to work (even on my local network, without adding ngrok into the equation)
While this command does function when referring to something like CUPS running on loopback (1337:localhost:631) it didn't seem to do it in this case.

Can I even forward the connection to the NVR in this manner

primal ice Feb 16, 2020, 5:34 PM

I assume you configured the settings or anything else for authentication from the ONT to the new router? Who is your ISP? I know for example in the states with AT&T you have to use their router but you put it in bridge mode to bypass it but you still have to use it for authentication to get into their network

primal ice Feb 16, 2020, 5:51 PM

#

technically you don't you just have to know pppoe information. account name default password . cause that is all their router is doing is setting up that connection. verizon/frontier was doing that here in washington when frontier took over from verizon.

#

then they went back to dhcp

clear igloo Feb 16, 2020, 5:52 PM

#

With AT&T they use 802.1x authentication and while you technically can get around it its a huge pain in the ass to do so

Hi guys, is there a device which connects to a 5ghz network and outputs the internet connection via RJ45? I want to connect a MoCA to a room with no reception but I don't have a coax port anywhere near my router. It's just a streamer so the degrade because of a wifi connection doesn't matter to me

A router/access point or computer with a wireless & ethernet NIC set to bridge the interfaces?

@dire flare For your NVR - I'd put a VPN server in some cloud, tunnel to it from your local router, then portforward whatever you need.

#

I used to offer such a service for various purposes, including for a company stupid enough to want their main webserver to be on a remote property in the middle of nowhere off a consumer 4G connection.

dire flare Feb 17, 2020, 12:26 PM

#

Well the SSH tunnel thing isnt working because RTSP seems to require both TCP and UDP port access and SSH only lets the TCP portion pass through. Though apparently there are ways to force it to only run through TCP, but I havent explored those options yey

#

Yeah, a tunnel ran over TCP :P

#

encapsulation intensifies

pseudo blade Feb 17, 2020, 12:36 PM

#

We ran SSTP or OpenVPN, masqueraded and port forwarded on cloud routers.

#

But in your case... perhaps you could just connect to the VPN server on the other end too. So that way you're not exposing RTSP to the internet.

#

So local network router with NVR > vpn through cgnat to public vpn server > vpn to your remote laptop you want to view your NVR from.

#

I pay like $3.50/month for a little VPN hosted in AWS so I can portforward.

Hey guys

#

I'm in a dilemma here. I have a pppoe internet connection which uses a username and a password from the middle man (ISP) which connects me to the actual provider. anyways, I used with him two types of ISPs A and B. A using a service name, HH and the other FNS. Currently I'm using the HH service name for the bundle i have from the isp. however, my router (Synology RT1900ac) gives me the chance to write anything as a service name or leave it blank. at one point i forgot to enter the HH and left it blank. i started using the internet and my internet jumped from the 5 mbits/s to 7 MB/s. i was blown away and it still is for now. when i use the HH again goes back to the normal 5 mbits. when i speedtest without the HH it shows that i'm using B's ISP which should necessarily need a service name, FNS. however, even with the B's ISP i was capped with them to 12 mbits not 45 mbits lol. What's happening here? Go technical if you please. i don't mind.

primal ice Feb 18, 2020, 12:05 PM

#

sounds like they are using QoS to limit/shape your traffic by service name and when you leave the service name blank it is bypassing that QoS (quality of service).

They do but they only see my usage as well as I can see it from A's ISP. B is more of a startup ISP which I stopped using them because if their connection inconsistency. So I think most probably B aren't on a very professional level in their infrastructure like A is.

#

I was hoping to set something up with 4TB or more

#

I have a laptop and desktop and would love if my ShadowPlay would record directly to the NAS so both have access to the same videos regardless of who recorded them

#

If that is even possible

#

Should I just buy those premade NAS' from WD with like 6TB?

cunning mango Feb 19, 2020, 2:35 PM

if you don't have like a buzz for homegrown server setups like r/homelab's or anything yeah probably

#

will save most likely hours of hassle

mellow heart Feb 19, 2020, 2:36 PM

#

The reason I was thinking of setting up my own NAS was because I have a spare desktop and would just need to buy it storage. I don't have much money so if it was a lot of saving I'd do that

#

but it seems like those solutions from WD are like $150 when I'd be spending at least $100 on building my own NAS... So doesn't seem like it would be worth it

I can't afford that so I might need to build my own just for the simple reason of not being able to afford anything

cunning mango Feb 19, 2020, 3:11 PM

see what you could do with that is just take tit plug it into your pc or laptop and be set with additional storage

#

windows does have a sharing option where you make make your files available over the network which works along as your pc is on and the drive is connected

mellow heart Feb 19, 2020, 3:49 PM

#

I want a solution that'll let me set ShadowPlay save locations for both my desktop and laptop so regardless of what I play on, it saves to the same place

#

and if possible, I'd like to be able to access those videos from anywhere

#

Is that possible with this?

#

I just realized, that if I set the save location to the NAS and I'm not home, that could be an issue...

#

So would I need to manually transfer them?

I dont know how this is called sorry.

Now i installed "Active directory Domain services" on my windows server 2016 and i am stuck on this screen.

@mellow heart you have an old system - install ubuntu and samba and some remote access software. when you are on your home network you can just use samba to access the drives and then when you are away out in the cloud you can use the remote access software to access ubuntu and then save your shadowplay captures.

@primal ice no bridge mode option, best i could do is to put a router we have and put it as dmz, but that router can only point to dns servers, not overwrite them itself to keep the request local

DMZ just bypasses the firewall from cloud to internal network.

you need a second fiber and second modem with a second account with 500

there is a unused extra fibre in the box still no diffrence if i use that?

waxen scroll Feb 22, 2020, 8:09 PM

im saying that your provider is throttling to 500 over that fiber and theres nothing you can do to speed it up outside of paying for more service

ok

craggy parcel Feb 22, 2020, 8:15 PM

If it's gpon, it's most likely because the fibers are already in the cable anyways, so why not just terminate them?

It's likely a redundant connection in case one breaks or something or a second run for something else but regardless how do you plan to get it to authorize on their network?

2 fibre moden and then connect these 2 moden into my router with lagg wont be any difference in bandwith but just fault tolerant?

clear igloo Feb 22, 2020, 8:25 PM

#

LAG is for redundancy or multi source/destination aggregation, it's not a combination of bandwidth for a single stream

hollow marlin Feb 22, 2020, 8:25 PM

#

The second fiber is just another strand in the splice

clear igloo Feb 22, 2020, 8:26 PM

You can get a 2 port modem but your ISP will NOT let you just plug in another cable for free, it will cost money to activate it

hollow marlin Feb 22, 2020, 8:26 PM

Nothing to do with lag

stiff panther Feb 22, 2020, 8:26 PM

@hollow marlin I assume that's some form of PON which, iirc, uses a single strand for both TX and RX? It looks like they just ran dual strand fiber to the prem but I'm not as familiar with all that stuff 🙂

hollow marlin Feb 22, 2020, 8:28 PM

I don't know of any PON that is duplex. All bidi

stiff panther Feb 22, 2020, 8:29 PM

My first taught was it goes to 2 diffrent switch at some sub station in the appartment

hollow marlin Feb 22, 2020, 8:30 PM

#

Usually at residential with the fiber going to the modem without a bulk head will have 2 or more terminated because if the customer breaks one they can quickly swap instead of re splicing.

Horrible way to do it though

@clear igloo If the ISP can identify the customer based on the line alone, then why not?

hollow marlin Feb 22, 2020, 9:08 PM

#

PON uses device registration, just MAC addresses, to allow a device on the network.

#

That's what's used to assign it a time slot

#

You cannot just plug in a second ONT and have it work

#

The actual fiber means nothing in PON. It's a shared medium

primal ice Feb 22, 2020, 9:16 PM

here there is a splitter box on the actual fiber line and they just plug a line from the splitter box to the ONT.

@fervent brook Microsoft only supports NIC Teaming on Server editions of Windows

#

Vendors support NIC Teaming through their own driver support

#

Intel comes to mind with this one.

#

Intel is also slow at patching their drivers when new feature versions of Windows 10 comes out

#

Complaining to intel doesn't make them work faster, even when intel admits the driver is broken

#

Lastly, they use the very slowest waterfall model for software development

fervent brook Feb 23, 2020, 4:14 AM

when I searched windows for "teaming", a random document popped up. I think it was a help file from the onboard nic supplier

fresh copper Feb 23, 2020, 7:02 PM

#

Microsoft if one of the only people that calls it “Teaming”. It’s more often called link aggregation. Usually set up with LACP but there are a few options. You might also hear it called port trunking (though this can get confused with VLAN trunking), link bundling, Ethernet/network/NIC bonding, channel bonding, or port channeling

little schooner Feb 23, 2020, 8:12 PM

#

@fresh copper do you think it's better to use LACP or Static trunking?

fresh copper Feb 23, 2020, 8:49 PM

#

You should generally only use static trunking if LACP is not supported

But there can be conditions for both

make sure the device is connected to the right tennant (IIRC this is an order possibilty with certain suppliers)

#

and let some guy/girl who understand wires and wire diagrams install it on side

and then you can easily configure it from your own office

this means you need less time for configuration

also expending is easy, just add it to the correct group

Meraki from an overall perspective isn't too bad to get going but it's a lot of clicking. I haven't really done any BGP with it or anything too advanced but it's definitely a lot lower learning curve over CLI for first timers 🙂

ACI isn't as bad as people make it out to be, it's just a different approach and a lot has improved. I remember when it used to be hot garbage but now it's really solid. I haven't used it a lot, yet, but what I have done has been pretty straight forward compared to the days of old

ASAP you start working at a company where they use HPE or Juniper most of your cert is useless

#

There are so many differences!

especially when you start putting VXLAN, EVPN, L2VPN and other "new" protocols from todays stack together.

If there was a cert like that, even I would probably take it. As then it's worth "something" for you!

jaunty talon Feb 24, 2020, 10:17 PM

#

If you look at most Tier1 ISP's today, non of them has CCIE/similar as requirement for their architects. And this is because in 3-4 years they might throw out all Cisco in favour for Arista or Juniper.

Therefor certs are almost only worth for Vendor partners, who gets higher partnership tiers based on how many certs they have!

Should I start off with virtualization to make it easier for me down the road or will I be able to take my pfsense config once I've completed it and drop it on it's own vm when I do everything else?

little schooner Feb 25, 2020, 12:06 AM

#

@knotty tartan yeah you are easily able to transfer pfsense config

ERL is like 5 years old tho

little schooner Feb 25, 2020, 2:20 AM

#

@waxen scroll why do they require many interviews?

waxen scroll Feb 25, 2020, 2:26 AM

#

it doesnt say how many

#

2-3 is standard

#

usually 2 phone calls, 1 on site

fervent brook Feb 25, 2020, 2:27 AM

#

what did we do in the last 5 years? invent RIP 3?

#

@waxen scroll how much would you pay for an ERL?

waxen scroll Feb 25, 2020, 2:29 AM

#

nothing, i'd get an edge router 4

waxen scroll Feb 25, 2020, 2:45 AM

#

i like how they lie to sell the job

#

OMG imma work with NASA all the time

#

i wonder if amazons super shitty office culture follows their cloud team

#

i usually tell amazon recruiters to take a hike

little schooner Feb 25, 2020, 3:03 AM

#

Thats a different interview im not used to

waxen scroll Feb 25, 2020, 3:04 AM

#

@little schooner theres a bunch of network engineers on my linkedin making fun of tesla offering $250k+ for a neteng job and saying how they wouldnt take that... lmao. i love when people see through the BS of these companies with bad cultures

little schooner Feb 25, 2020, 3:04 AM

#

but yeah they sell it like its incredible

#

My career teacher is urging me to get linkedin

#

but I dont really want one

waxen scroll Feb 25, 2020, 3:05 AM

#

plus F living in CA where my house would cost me $3,000,000

little schooner Feb 25, 2020, 3:05 AM

#

Yeah, very expensive down that

waxen scroll Feb 25, 2020, 3:05 AM

#

you need one. sorry not sorry

#

no other website does tech jobs better than linkedin

little schooner Feb 25, 2020, 3:05 AM

#

Now what would be awesome is getting a job that exists in one state and living in a cheap cost-of-living state with that expensive state's pay

#

doing remote work

#

cali wage in florida for example

waxen scroll Feb 25, 2020, 3:06 AM

#

im working on that myself, its hard. companies like that are smart AF and because they allow 100% remote, they know they can pick top 1% of skill level

#

very elitest

#

also a lot of them are startups, so shit culture

#

80hr work weeks, whatever

fervent brook Feb 25, 2020, 3:14 AM

#

one time I refused to sell someone alcohol because they were drunk, and when I told them to leave the property, they proceeded to stand outside yelling, "I work at Amazon"

#

someday, I wish to attain that sort of pride in my job

#

is "CA" California or Canada?

waxen scroll Feb 25, 2020, 3:16 AM

#

California, but I'm sure parts of Canada aren't far behind

fervent brook Feb 25, 2020, 3:32 AM

#

at this point, im so used to the laws in my state/state, im worried that if i accidentally wonder into another state/state i might have to utter the phrase "what do you mean it's illegal to talk rudely to someone, even if they're trying to stab me with a knife?" unironically

Ok so i've got my pfsense config up and running and the first package installed was pfBlockerNG. I've tested it out on a few sites and it's working well but am I wrong in assuming it would block ads on youtube videos?

little schooner Feb 25, 2020, 4:51 AM

#

I recommend PiHole for ad blocking. Haven't used the pfsense for ad blocking

#

But im sure it exists as a different package on pfsense

knotty tartan Feb 25, 2020, 4:57 AM

#

I haven't seen a package for pihole but everything that I've read is pfBlockerNG uses the same lists as pihole

#

but I've got ads on my youtube

primal ice Feb 25, 2020, 6:12 AM

#

use ipv6 as an adblocker. works great. :p

#

have all my browser traffic through a ipv6in4 tunnel. ever site thinks I am using an ad blocker.

is there a place all the cool kids buy their com ports?

thick minnow Feb 25, 2020, 7:52 AM

#

Idk

fervent brook Feb 25, 2020, 7:52 AM

#

damn

#

ive got like 2 rollover cables, and my motherboard has a connector, but i need to buy a com port. at this point i might just buy a com port board and take the port from that

#

https://www.amazon.com/Cables-Go-02882-Serial-Adapter/dp/B00005114T

fallow frost Feb 25, 2020, 7:57 AM

#

So is a com port just the male connector for vga cables?

fervent brook Feb 25, 2020, 8:02 AM

#

no

#

VGA as you probably know it use DE15

try and plug them into eachother. i dare you

fallow frost Feb 25, 2020, 8:06 AM

#

Eh, just bend a few pins

#

I'll try tomorrow Kappa

fervent brook Feb 25, 2020, 8:09 AM

#

if you have a computer with a CGA port, you'll have better luck

#

that uses the same pin layout and number

fervent brook Feb 25, 2020, 5:13 PM

#

I just had a really stupid idea.

#

Buy an RJ-45 keystone jack, wire it directly to my RS-232 pinout on my motherboard, use that for Console access

So long as it's not over 50 feet then you're good

sturdy mirage Feb 25, 2020, 5:43 PM

#

the dumbest implementation of à console port I have seen is on alcatel switches,
there is an RJ-45 console port with a proprietary pinout, you need à crossover cable to connect this port to à DB9 adapter, then you need an other adapter to connect to à laptop in USB.

#

why not just use the Cisco pinout ?
or even put à micro USB, like HP/HPE...
no one will ever know...

waxen scroll Feb 25, 2020, 6:05 PM

#

@clear igloo baby, hi

#

we did that hack in the datacenter and i believe it works way over 50 feet

#

its been years tho, dont remember

#

putting console through patch panels

clear igloo Feb 25, 2020, 6:12 PM

#

@waxen scroll I just did a quick google search and that's the first estimate that came up 😛

@sturdy mirage Cisco has also used USB for awhile now. Don't remember if both routers I have access to are miniUSB, or one is micro.

#

putting console through patch panels
@waxen scroll Looks funny when you plug in the console cable in the wall jack.. 😉

waxen scroll Feb 25, 2020, 6:50 PM

#

i tend to use USB when available, however other equipment hasnt caught up, so you have to carry DB9 anyway

craggy parcel Feb 25, 2020, 6:52 PM

#

Yeah, I also use USB when I have the option. No need to worry if the USB->RS232 dongle will work with that particular device, they picked a chip that just works. 😉

Bonus is, the driver is already available on my mac. 🙂 Just a matter of screen /dev/tty.usbsomething 9600
