@thick minnow I need to route a gig Oh get an R620 and a pair of SSDs, run pfsense

#

An R620 to route gigabit :P

#

A pair of SSDs? for the massive quantity of disk IO routers do, I assume :P

#

Gigabit's cheap to route, get your redundancy from buying two cheap MIPS/ARM routers instead.

thick minnow Oct 1, 2019, 7:34 AM

#

I may have phrased that wrong

#

I'll have to fix that

#

Yeah... that went over my head.

I see the sarcasm

Quick Question

#

what do you guys call a disconnection that only lasts 1 to 2 seconds

waxen scroll Oct 1, 2019, 2:01 PM

#

a blip

#

thats the technical term we use in enterprise networking

#

ltt

clear igloo Oct 1, 2019, 2:12 PM

#

We call that a browser refresh 😛

hallow nimbus Oct 1, 2019, 2:33 PM

#

That takes 2 seconds demn

distant wedge Oct 1, 2019, 2:52 PM

#

hahah

#

Thanks guys, couldn't get the word in my head today

clear igloo Oct 1, 2019, 2:53 PM

#

Usually any event that results in traffic loss is called a "convergence event" where traffic finds another path. Traffic that just dies as a result of some event is called "black holed" usually when it has no path to the destination

distant wedge Oct 1, 2019, 2:54 PM

#

That would make sense

#

now to deal with these broadcast storms

hollow marlin Oct 1, 2019, 3:16 PM

#

@distant wedge you didn't disabled STP did you?

distant wedge Oct 1, 2019, 3:20 PM

#

no, someone brought a switch from home and plugged two of their ports into their allocated office space.

#

Why? Who even knows

hollow marlin Oct 1, 2019, 3:24 PM

#

BPDU guard

distant wedge Oct 1, 2019, 3:27 PM

#

Yeah no, they're on a slave switch, but a lot of mission critical stuff is on that switch as well

#

So when I looked at the device tree and all those devices were offline I was like awwwwww shit

hollow marlin Oct 1, 2019, 3:32 PM

#

@distant wedge that's exactly bwhy you put BPDU guard on the aceess ports

distant wedge Oct 1, 2019, 3:32 PM

#

Lol, I'm just the junior here so I don't have as much access as you'd think

#

I can only "recommend" things to my senior

#

I told him about it and he's like "noooooo, it has to be IGMP, there's no way" I'm like "ok have fun"

hollow marlin Oct 1, 2019, 3:33 PM

#

This is a good time to show them what impact it has when it's not enabled, as you just found out

distant wedge Oct 1, 2019, 3:33 PM

#

They don't want to listen to me, lol

#

Right now they're running wireshark and watching things

#

I'm like "okay"

clear igloo Oct 1, 2019, 3:34 PM

#

lol

hollow marlin Oct 1, 2019, 3:35 PM

#

You should tell them to read what IGMP actually does

distant wedge Oct 1, 2019, 3:35 PM

#

I have, they told me not to be insubordinate

#

eyes_sus

#

Startin to really think about this company now lol

clear igloo Oct 1, 2019, 3:36 PM

#

I'd wager they disabled BPDU guard or failed to configure access ports correctly. If they disabled STP, run

im sitting here shitposting on discord while they sort their shit out. Their excuse is that because they configured it before I was hired, I have no say on what they should do because the settings worked before I showed up...

I haven't touched a single thing because I don't have access to anything, no switches or servers, lol

#

not even switch management console

clear igloo Oct 1, 2019, 3:38 PM

#

Mission critical apps on the same switch as end users is just horrific design

distant wedge Oct 1, 2019, 3:38 PM

#

Try explaining it to them

hollow marlin Oct 1, 2019, 3:38 PM

#

Are you off the same switch?

distant wedge Oct 1, 2019, 3:38 PM

#

They have this stupid thing where they're all sharing the same VLAN regardless of what the device is because it's easier

#

I was like what the fuck

clear igloo Oct 1, 2019, 3:39 PM

#

RUN... FAR

distant wedge Oct 1, 2019, 3:39 PM

#

I want to 😭

clear igloo Oct 1, 2019, 3:39 PM

#

Is it at LEAST not VLAN 1?

distant wedge Oct 1, 2019, 3:39 PM

#

Yes, they have it set to like 125

#

@hollow marlin I'm running on the same switch through an AP

#

according to my superior, going wired into the device isn't best practice

hollow marlin Oct 1, 2019, 3:40 PM

#

Run Wireshark and tell use what you see

distant wedge Oct 1, 2019, 3:40 PM

I've heard so much bs today I want to call it a day

clear igloo Oct 1, 2019, 3:41 PM

lol, I would if I wasn't hourly

clear igloo Oct 1, 2019, 4:02 PM

@distant wedge You should pull up design guides and the RFCs for STP and PVST 😄

distant wedge Oct 1, 2019, 4:51 PM

@clear igloo SO real quick, my superiors superior came up to me and asked me why I was on discord. I was like "I've got nothing to do. 'x' said he doesn't want me touching the hardware, so I'm respecting his wishes"

little schooner Oct 1, 2019, 5:41 PM

#

Is it necessary to have the transport input command assigned to vty lines in order to ping a Cisco switch from a host in the same vlan as Cisco switches svi?

waxen scroll Oct 1, 2019, 5:41 PM

#

no

little schooner Oct 1, 2019, 5:41 PM

#

I know I have done the configuration correctly, but my vms inside of esxi host is not passing the tag along or something to reach it

#

The esxi host is connected to Port fa0/48, set in trunk mode allowing vlans 99-200

waxen scroll Oct 1, 2019, 5:42 PM

#

esxi... 100mbit? bruh

little schooner Oct 1, 2019, 5:42 PM

#

VM is using tagged port group in esxi virtual switch vlan 99

#

@waxen scroll yes its for a lab lol

waxen scroll Oct 1, 2019, 5:43 PM

#

whats the SVI number

little schooner Oct 1, 2019, 5:43 PM

#

In theory it should pass through to virtual switch and then to physical trunk port.

#

It is vlan 99 on svi

#

I did interface vlan 99

#

No shut

waxen scroll Oct 1, 2019, 5:43 PM

#

"show interface vlan99"

#

is it up/up

little schooner Oct 1, 2019, 5:44 PM

#

I won't be able to check that right now. It's at the school :(. I only have the config available

#

But what if it was up/up?

#

What else could be it?

waxen scroll Oct 1, 2019, 5:44 PM

#

then tagging is messed up somewhere in esxi

little schooner Oct 1, 2019, 5:45 PM

#

Will have to double check all of that.

thick minnow Oct 1, 2019, 6:36 PM

#

You know those power line adapters? How fast are those in the real world?

hollow marlin Oct 1, 2019, 6:59 PM

#

@little schooner did you remember to create vlan99

little schooner Oct 1, 2019, 7:00 PM

#

@hollow marlin well creating interface vlan 99 automatically creates vlan in vlan.dat

#

But yes, I did it anyway

hollow marlin Oct 1, 2019, 7:00 PM

#

Eh.....not all the time

little schooner Oct 1, 2019, 7:00 PM

#

I did remember typing vlan 99

#

Name management

hollow marlin Oct 1, 2019, 7:00 PM

#

Always create vlan just in case.

little schooner Oct 1, 2019, 7:00 PM

#

Yeh true

#

@thick minnow most I got was 60mbps

#

On the same circuit

#

My brother got measly 5 mbps off a 50mbps connection

hollow marlin Oct 1, 2019, 7:02 PM

#

But yea, check SVI up/up and if it is, show mac add and see if any tag traffic is appearing on the trunk with the ESXi mac

little schooner Oct 1, 2019, 7:02 PM

#

But he was in apartment

#

Alright I will be sure to do that probably Friday when I am back there

thick minnow Oct 1, 2019, 7:26 PM

#

Ooof, yeah I couldn't use one of those, It was gonna be from the media converter, to the gateway. I have FTTH

little schooner Oct 1, 2019, 8:50 PM

#

@thick minnow I want that next just need to wait until next year for the new competition to oust Comcast

#

I wish I had a direct connection to someone who works there

#

I could get my area prioritized

waxen scroll Oct 1, 2019, 10:44 PM

@little schooner that professor needs to pay

little schooner Oct 1, 2019, 10:53 PM

@waxen scroll in regards to what?

waxen scroll Oct 1, 2019, 10:54 PM

you

little schooner Oct 1, 2019, 10:54 PM

#

Ahh. Yeah i agree.

waxen scroll Oct 1, 2019, 10:55 PM

#

i'd be charging $100/hr... $60/hr if i like the guy

little schooner Oct 1, 2019, 10:55 PM

#

I'd like to be hired by the school to work with him as the cybersecurity program assistant but

#

money is tight for the school

#

At my university, they are rolling in it, but they have everything figured out nicely

#

If anything, my 2-year college is firing IT helpdesk and server admins

waxen scroll Oct 1, 2019, 10:56 PM

#

i noticed when you said 100mbit

little schooner Oct 1, 2019, 10:56 PM

#

Yeah. Basically, when they hired my professor, they were teaching networking courses without any of the cisco hardware in the classroom

#

and no computers for the students to use.

#

Guess how he managed to get 20 computers in the lab?

waxen scroll Oct 1, 2019, 10:57 PM

#

u

little schooner Oct 1, 2019, 10:57 PM

#

No. IT for the 2-year school was throwing out older systems and my professor happened to see them in the hallway next to elevator

#

and he asked if he could have them and they told him sure... as long as you carry it

#

so they didn't even want to help him move it

#

and then he started testing with an all Ubuntu-system classroom layout

#

that worked good for a good 3 years until I showed up.

#

When I showed up, I got aquantied with him a bit more and it turns out we share a common passion for the work we do

#

As we went along, we were getting attention and started being able to get grant money

#

But a lot of these things have to wait until break in order to implement them

#

Like summer is when we implement our biggest projects. whether that is new servers, lab makeover, etc

#

and implementing a platform that is complex in documentation (but easy once you do it once) kinda stuff

#

@waxen scroll its funny because the old female professor who was teaching networking class claimed that she used the lab layout we have now to teach students, when she didn't even have the motivation to institute any kind of good change for the benefit of student learning

#

It was all our work and she was taking the credit in front of this new dean guy

#

@waxen scroll the improvements were so vast that we are planning on finding money to convert the classroom into two-classroom sized room. The room next door is unused and for certificate program in CompTIA+. Then, we will have a nice glass enclsoure where our server racks will be in a freestanding rack that the students can look around 360 degrees. Another rack will have equipment students can grab and take to their desk if they want to do some physical work with switches or routers. Lastly, throw in some digital signage and displays in the room and have a massively sized network map print out on the wall

#

Its going to be a fun summer once we get to that point.

#

@waxen scroll I promise this is my last statement about this lol but my friends were saying how lucky my prof is to have someone me him help him out with all these things. Of course, I make sure to leave him docs so he can fully take over once if I were to leave the state or anything. Make it easier for the next people who take charge of it. I just hope they do it with students benefit in mind.

@little schooner when you learning coding?

unkempt ferry Oct 2, 2019, 12:16 AM

#

If I want to install IW-HDs in multiple rooms upstairs, would it be a better idea to run a single cat6 up there to a switch and then split it to each AP or should I run individual cables to each AP?

hollow marlin Oct 2, 2019, 12:32 AM

#

@unkempt ferry Id run to each if possible

little schooner Oct 2, 2019, 12:45 AM

#

@waxen scroll coding like java or python?

waxen scroll Oct 2, 2019, 12:46 AM

#

yes

little schooner Oct 2, 2019, 12:46 AM

#

@unkempt ferry I've tried splitting it between APs and it was a disaster when it came time to upgrading the firmware on them. That meant that they disabled internet access briefly to the whole household

#

I re-ran everything to have its own single cable towards a single switch

#

@waxen scroll Well, not formally yet. I need more motivation to start

unkempt ferry Oct 2, 2019, 12:47 AM

#

Ok I’ll go with single runs for everything

little schooner Oct 2, 2019, 12:47 AM

#

Maybe during the break

unkempt ferry Oct 2, 2019, 12:47 AM

#

Thanks for the advice!

little schooner Oct 2, 2019, 12:47 AM

#

No problem

#

@waxen scroll I've been scripting more in powershell

#

would anyone recommend Freenas for Nas and Plex server? I was gonna set up a raspberry pi to transfer new movies over to the nas for plex

little schooner Oct 2, 2019, 1:35 AM

#

I'd recommend freenas. But I also recommend Synology NAS even more.

#

Synology's GUI is simply fantastic

ornate jungle Oct 2, 2019, 1:52 AM

#

can confirm; and synology does support SSH access if you need to do advanced stuff

small prism Oct 2, 2019, 3:16 AM

#

yeah but synology is 'spensive

ornate jungle Oct 2, 2019, 3:41 AM

#

True that; much of what you're paying for is the small form factor, lower noise level, and customized Linux based OS. I'd love to justify a Micro-tower server in my living room, but just can't.

lean pollen Oct 2, 2019, 11:22 AM

#

I recomend Unraid unless you actually need lots of speed or its for a big company or whatever

unkempt ferry Oct 2, 2019, 1:32 PM

#

FreeNas is better

little schooner Oct 2, 2019, 1:40 PM

#

@unkempt ferry better in what way?

#

It's definitely not in support and GUI

#

In price, sure.

#

Last time I got help from synology, a single packet tracer file was all they needed to diagnose my problem with smb 3

#

They were super knowledgeable

unkempt ferry Oct 2, 2019, 1:42 PM

#

I mean for it being free, it offers pretty good features

little schooner Oct 2, 2019, 1:42 PM

#

Yes, no doubt about it

#

For free tier.

#

We bought a synology for a smb because they wanted a number to call and something that just works

unkempt ferry Oct 2, 2019, 1:48 PM

#

Well Synology is good is you have the cash for it

waxen scroll Oct 2, 2019, 2:10 PM

@hollow marlin that feel when you go into python shell on Nexus switch

subtle glen Oct 2, 2019, 4:42 PM

#

To make a site to site vpn, do you need a router that supports that or it's something you can run off a server?

waxen scroll Oct 2, 2019, 4:47 PM

#

Server can work

#

You may need to do something with static routes on your routers though

subtle glen Oct 2, 2019, 4:51 PM

#

Hope there's that on the isp modem lol

lean pollen Oct 2, 2019, 5:31 PM

#

Data is more safe inn Unraid than Freenas

#

Because data is not striped

little schooner Oct 2, 2019, 6:26 PM

#

@waxen scroll you have to program for the nexus switches?

#

Or is it for added flexibility?

#

Like playing around with frames and packets based on some logic

clear igloo Oct 2, 2019, 6:35 PM

#

Added flexibility, you can run python and whatnot on the box

#

Even spin up VMs if you're so inclined 🙂

little schooner Oct 2, 2019, 6:36 PM

#

@clear igloo actually, it kind of reminds me like how edgerouter can accept Debian packages to extend the router's functionality

#

Except it isn't package, it's whatever code you make it do

#

A VM? Well...

#

They must be beefy

clear igloo Oct 2, 2019, 6:37 PM

#

Yah, it's got virtualization support, not sure how in depth but I know it exists on some of the lines

little schooner Oct 2, 2019, 6:38 PM

#

Yeah that's real neat

clear igloo Oct 2, 2019, 6:38 PM

#

Am I blind or are there only 4 wires in this picture?

4 wires yeah

clear igloo Oct 2, 2019, 6:39 PM

#

Just making sure I wasn't having trouble seeing 🙂

little schooner Oct 2, 2019, 6:40 PM

#

That is real tricky

#

Also the orange one looks as if it's take both white orange and oranges spot with single wire

#

But that can be done if you force it in hard

clear igloo Oct 2, 2019, 6:40 PM

#

I was partially incorrect when I said VMs earlier. It's more of a container based solution for Docker and whatnot; https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/92x/programmability/guide/b-cisco-nexus-9000-series-nx-os-programmability-guide-92x/b-cisco-nexus-9000-series-nx-os-programmability-guide-92x_chapter_010010.pdf

little schooner Oct 2, 2019, 6:41 PM

#

My first introduction to Docker was with an appliance called xibo

#

Got to say, much better setup procedure without the messy server and config files editing

clear igloo Oct 2, 2019, 6:42 PM

#

Yah, you won't run a full blown Windows VM in most cases but a nice lightweight linux distro is perfect

waxen scroll Oct 2, 2019, 10:45 PM

#

@little schooner my script is done for the most part

#

it takes your login info and asks what switches to use... you define as many as you want

#

"show ip arp vrf all | i Vlan|Eth"

#

stores the output into a file, cuts some extra stuff out, deduplicates entries, makes a CSV

#

it'll do more later

i guess thats normal right?

radiant crane Oct 3, 2019, 1:32 PM

They might throttle your WiFi speeds for what ever reason

#

What's your speed when you plug in wired?

ember phoenix Oct 3, 2019, 1:34 PM

#

10Mbps

#

📎 unknown.png

radiant crane Oct 3, 2019, 1:36 PM

Yeah I would call them, if you bought 100 you should get 100. Are you using their modem?

ember phoenix Oct 3, 2019, 1:36 PM

#

yes

#

here is something you should know

#

by wired i mean im connected to the router via lan

#

The actual setup is

#

There is an Antenna at the 12th floor

#

which sends a wire down

#

wire plugs into router

#

and im plugged into the router

radiant crane Oct 3, 2019, 1:38 PM

#

Is it your router? Like one you bought?

now they are throttling my speed i think

radiant crane Oct 3, 2019, 1:39 PM

Yeah, looks like it. You're correct that you shouldn't be getting 10 Mbps

ember phoenix Oct 3, 2019, 1:40 PM

#

an hour ago a guy came coz i reported some stability issues

#

i asked him about this speed thing

#

being reduced now

#

he said "you were getting high speeds coz of more bandwidth "

#

and said that the speed right now is normal

#

i just want to know whether the ISP is scamming me

radiant crane Oct 3, 2019, 1:43 PM

#

I mean are alot of people home right now from work/school over where you are?

home

#

and only i am connected the to internet

radiant crane Oct 3, 2019, 1:44 PM

What timezone are you in? They might throttle everyone down during peak hours

ember phoenix Oct 3, 2019, 1:45 PM

#

i am in IST

#

(indian time)

#

and i dont think they are throttling in peak hours

#

its 7pm here right now

its been like that

@thick minnow there are more than just cost with WISP

pseudo blade Oct 4, 2019, 5:13 AM

@ember phoenix Yeah if a wireless internet service provider's offering "100mbps except for all the wireless users" it's clear they're using deceptive marketing techniques and you should tell them where to shove their service.

@hollow marlin I think they would like to stream recordings to a smart TV, but the primary will be a direct from camera to monitor situation. The client is an oral surgery school, and they will be doing live procedures that students will be observing.

hollow marlin Oct 4, 2019, 9:49 PM

#

I guess it will depend on but rate. I cant see it reaching a gig/s but still unknown

clear igloo Oct 4, 2019, 9:59 PM

#

Depends on the camera/codec/compression, and framerate, 4K video (24fps) can easily crush a gigabit pipe and push up towards 3+ Gbps depending on the camera and codec. I think RAW 4K video can do somewhere in the 2 to 3 Gbps range and depending on the fidelity of the 8k footage, which I hope is not too high, you could go MUCH higher than that

#

IEEE mentions 257Gbps per channel for UHD uncompressed 8k footage 😄

#

Obviously there will, or hopefully there will be, compression of some sort which would probably put you in the gigabit range for 8k footage though

hollow marlin Oct 4, 2019, 10:04 PM

@clear igloo a packet pushers podcast has a video engineer for a live broadcast company. He was talking about complexity and their raw 1080p footage was 7gbps.

I would have to go through a bunch of legal stuff to start a business, learn how to make a DHCP server or manually assign IPs, I would also have to buy an IP Address pool. You also have to abide by the US Government and do whatever they want you to do, part of what I assume is assigning IPs. Not only that but I have to learn the security side of things too to prevent from being hacked or getting DDoS attacks. Im thinking of having the equiptment on farming equiptment like grain houses and stuff like that. I also have to find a base site that isn't too far from fiber, the more fiber I have to build to the main site the more it will cost.

#

I'm sure there might be some that I am missing. Let me know.

#

I could probably physically set it up. But I wouldn't be able to set the IP addresses ip. Idk how things work ISP side.

what if the username is nonsense like #$%^$ or contains escape characters?

@waxen scroll That's where making GUI out of script function logic comes in handy, this way they are restricted to what they can do. Although, yes, you still need to do some input validation, but in C#, it does not take as long to do with a shared function. Yes, its more work :/

clear igloo Oct 5, 2019, 6:30 PM

Well a wifi extender is problem number 1 because distance away from the router reduces the speed alone and then a repeater will pretty much cut that in half to repeat the signal

#

Couple that with any other load on the network, interference, etc. and you can easily see good speed drop way down

Do you think a 1 gbps backhaul would be good for up to 400 people? Each customer will have 100 Mbps speeds. I know it's slightly over selling, but not everyone is going to use their 100 mbps connection the whole time.

#

If everyone went like full balls to the wall at the same time, each internet connection would be limited to 24 mbps.

Probably actually 20 mbps

Cause 1 Gbps isn't 1000 Mbps, it's more like 940 mbps

Well it only has a single gigabit WAN port so that's problem number 1 and that 2000Mbps is theoretical maximums based on a tri-band AC capable device in perfect lab like conditions and you'll never get that in the real world, let alone outside of the router since it doesn't even have a physical port capable of sending more than 1Gbps

^ Okay, I agree with this. If you really want 5 GB/s of speeds, you’ll need to use CAT 7/Fiber. Another point: even if you use the types of cables above, you’ll never reach those speeds due to bottlenecks with spinning drives.

#

Another way to go about that would to use RAM disks if you really wanted to use storage at 5 GB/s

Cat5e can do 5Gbps up to 30m, anything more and you need Cat6 or Cat6a for copper

@waxen scroll okay, so now that I'm home, I was able to diagnose the problem. Turns out, the scheduled task I created to autorun a web service application was set to automatically terminate after 3 days of running time. Since the service task never stops (unless crashing or manual stop), it was easily going to go over 3 days. So at three days, it terminated it all. I've adjusted the config to NOT have it stop running after x days and now it should be working better.

I found a few small cases to manipulate show command info but I also can't find a major use case. Too many people running around telling us that coding is the future for networking.

#

We use Excel template for major stuff and it seems to me that it makes more sense to do that then to give a script the information live and potentially screw it up

#

What are you trying to do with Netmiko?

waxen scroll Oct 9, 2019, 1:52 PM

#

Two things right now. One is an arp scanner which scans multiple cores, dedupes, then does dns and ipam lookup before dumping into an Excel sheet. This is a report for maintenance. Next is a VRF scanner. Take a VRF name and get the configs for it across all network devices. My issue is I can't do an array without textfsm and have to dump to a text file then import to an array/list

radiant crane Oct 9, 2019, 1:53 PM

#

And why can't you use TextFSM?

waxen scroll Oct 9, 2019, 1:54 PM

#

I can use textfsm but there's more bullshit involved. I have to learn it. It also makes it harder to distribute the script unless I make a jump server with all the dependency like custom textfsm definitions

#

Yes it's me being lazy. I'm just curious

radiant crane Oct 9, 2019, 1:55 PM

#

Yeah I get that

#

I did two things before I learned TextFSM. I made an array by separating at the space " " or I counted the characters I knew the output would be

#

Example 1:

  MAClst = [];
        for char in showMAC:
            MAClst.append(char)
        MACvarsplit = (''.join(MAClst).split('\n'))

#

Example 2:

interfaces = [];
for line in showMAC.splitlines():
        #only grabs interfaces that are not equal to userVLAN
        if line[2:4] != userVLAN:
            interfaces.append(line[38:47].strip())

#

But of course TextFSM is so much easier

lldp = net_connect.send_command("show lldp neighbors detail", use_textfsm=True)

    # iterate over the list
    for lldpf in lldp:

        # grab only "W" capabilities
        if lldpf['capabilities'] == 'W':

            # grab some information
            ap_ip = lldpf['management_ip']
            ap_port = lldpf['local_interface']
            ap_name = lldpf['neighbor']

little schooner Oct 9, 2019, 2:02 PM

@radiant crane VRF use really depends on your use case. What are they using them for/what scale

radiant crane Oct 9, 2019, 8:40 PM

#

We use VRFs for every network, so security cameras vrf, staff vrf, guest vrf

So when you're troubleshooting you'll do sh ip ospf neighbor

#

why are you calling comcast on it?

#

@hollow marlin job = ?

little schooner Oct 9, 2019, 11:20 PM

#

@waxen scroll my professor got a call from the dentist doctor, complaining that their entire network is down. Router had internet access, workstations had internet access. Domain controller was somehow changed from static IP to DHCP setting.

Told prof that Comcast Gateway defaults to Router mode when it's reset and that's when the problem starting getting worse. When you factory reset this particular router, it keeps the old static ip address. He couldn't connect to it. The modem was purchased today from a best buy and connected immediately

#

Then only the IP phones didn't work. Everything else was. Unfortunately, prof had to be in lecture by 4 something, so the fastest solution was to call Comcast to fix the problem

#

But then Comcast told him that modem that was bought didn't fully support bridge mode.

#

Obviously a lie but can't believe they speak misinformation like that.

Mind you, this is all happening during my physics class lol

@waxen scroll the doctor also grew impatient, so I guess calling Comcast was the last comfort resort to show that progress to solve problem was still rolling forward

@little schooner Requirements: 2x Simulated WAN provider, 2x remote office connected to simulated WAN (WAN1 to office 1, WAN2 to office 2), 1x Datacenter WAN edge router (2 VRFs one per provider, and global tables), 1x firewall connected to DC WAN edge, 1x switch connected to FW (DC LAN), 1x simulated server

#

I need you to provide resources from the server to remote office 1 and 2 without allowing them to anything else in the datacenter or between themselves. you may not share a default route or routing tables from the datacenter into their networks

#

you may not leak their internal routes into your datacenter or share between remote offices

#

because you're new, ill give you a huge hint... that firewall needs to do some sort of NAT. If you generate routes for this NAT, you can share them to the WANs but dont share the same NAT address with office 1 and 2.

#

draw it and someone will tell you if its good enough to start labbing

Is there anything with 6 over 5 that really makes a difference?

little schooner Oct 10, 2019, 5:52 PM

#

Not sure if this was common knowledge, but, when I tried to use my Gmail account for alert monitoring of servers and stuff, Google would actively refuse to accept credentials of my account, even with "Turn on less secure access" setting. It would ask me if it was me who logged on and I clicked the "Yes it was me" button to add it as a trusted logon source.

Nope, that wasn't enough either. Still getting silently blocked when server tries to use SMTP settings to send test email. What got it to finally work was to enable Two-factor authentication on Gmail account and then use an App Password. It immediately accepted the app password when server tried sending test email again and went through. I was able to get the email.

So in other words, Google errs on the side of mandating App passwords instead of regular password with no two step for personal accounts?

#

@radiant crane i got half my VRF script done but i ran into an annoying issue on ASR9k / ios-xr

#

if destination in (0.0.0.0/0) or destination in PS_LURICK or destination in PS_JAKE_HATES_TECH```

#

im not sure how to get it so the script can read that second line and go "OK, ignore any IPs in ( ) and make an array of the prefix-set names"

#

right now i use textfsm to match show run and dump anything that comes out into an array

#

i then loop the array to look for "if" and then it does an awk type deal to isolate each word

#

so if i say array['config'][3] i would get PS_LURICK ideally... if (0.0.0.0/0) shows up instead it shits itself at the moment

#

problem is if i try to fact find using [3] and keep going up, eventually the script will get an exception

#

before you answer, i also want you to know that second line is dynamic in length

#

some might be 1 destination, some might be 10 (lets just argue)

#

this crappy problem is the last one i have to deal with for IOS-XR... then i move onto the NX-OS part of the script

radiant crane Oct 11, 2019, 12:10 AM

#

You would use something like

if "something" in output:
    do_something
else:
    do_something_else

#

But you would have to show my the TextFSM output so I can see

waxen scroll Oct 11, 2019, 12:31 AM

#

the output looks like this

#

im not at work so im just freehanding

#

['route-policy block Xeon'], ['if destination in (0.0.0.0/0) or destination in PS_LURICK or destination in PS_JAKE_HATES_TECH']

#

im running a "show run route-policy Xeon"

#

the reason textfsm outputs like that is i need it all in an array so i can dump it into an excel file

#

its a VRF crawler that dumps the configs for the VRF into excel

#

if the VRF is calling a global object such as a route-policy, the script goes and investigates that so it can be included

#

i could potentially run it in textfsm a second time under a special template as well, but like i said its dynamic length and the (0.0.0.0/0) can be anywhere

#

textfsm doesnt seem like it can handle either of those two things

#

ive only seen textfsm templates for data thats always in the same spot and same-ish length

#

@little schooner please run that VRF lab

#

i cant tell you how much further ahead of like 70% of "network" people you'd be just knowing that

That I did not do. The only "power cycle" that I've done is simply to the IPMI interface itself.

#

I can't power off the server until like 11pm though, its being used at the moment

I was hoping maybe resetting the IPMI interface itself would cause it to work again

Does anyone know how to portforward an ipv6 for hosting games like rust or minecraft?
Do i set a static ipv4?

craggy parcel Oct 11, 2019, 7:00 AM

#

@thick minnow Usually you don't have to make any port forwarding for IPv6, you already have a public address accessible from the entire world. (... World of IPv6 connected devices that is) But most routers do not allow inbound connections, for security reasons. Look for some sort of firewall settings in your router, and make the appropriate rule.

thick minnow Oct 11, 2019, 9:10 AM

#

@craggy parcel How do i allow friends to connect?

#

Say i portforwarded, do i give them my ipv6 or ipv4?

craggy parcel Oct 11, 2019, 9:11 AM

#

@thick minnow I don't think we're on the same page here...

#

@thick minnow Consider this logical layout of your network...

📎 unknown.png

#

The blue line is IPv6 traffic, the red line is NATed IPv4 traffic..

#

The IPv6 traffic is NOT passing through NAT, and therefore you would NEVER need to make port forwardings for IPv6 traffic, it is usually filtered by the router, so that only responses to traffic you initiate is allowed through. You need to configure the router to allow IPv6 traffic inbound to the game server.

The IPv4 traffic is passing through NAT, and you will need to make port forwardings to make things work.

What IP you need to give to other players, depends on wether you need them to use the blue, or the red route. If at all possible I would play over IPv6, as that will give totally bypass NAT and all it's mangling of the packets.

thick minnow Oct 11, 2019, 9:32 AM

@craggy parcel The problem that i encountered first was while i tried to play minecraft with my mate

#

He couldn't connect regardless of me adding exceptions in my firewall and shit

Anyone online wanna inform a noob on VLans and DHCP?

clear igloo Oct 11, 2019, 12:40 PM

#

VLAN - Virtual segmentation of a physical network into multiple logical networks
DHCP - Dynamic Host Control Protocol - Host broadcasts a request and the first server to respond with valid information will then give the host various information including an IP address, Subnet Mask, Gateway, etc.
VLAN + DHCP - Uses a helper address per SVI (layer 3 gateway) to redirect the DHCP request to the DHCP server(s)

#

Expand on what you want to know and I'll deep dive on that 🙂

austere scroll Oct 11, 2019, 12:43 PM

#

So what I was wondering was is it possible to have a DHCP server running on both the LAN and VLAN without them conflicting?

Like if I plugged in a server, how does the server know whether to get an IP address from 192.x.x.x or 10.x.x.x?

#

I have got all unmanged switches in my network btw

#

If it's not possible, what's the best way to assign addresses to devices on the VLAN? Does it all have to be manual?

clear igloo Oct 11, 2019, 12:44 PM

#

What kind of DHCP server? Windows? Linux?

austere scroll Oct 11, 2019, 12:44 PM

#

PFsense

clear igloo Oct 11, 2019, 12:45 PM

#

Ah, so on the router then

austere scroll Oct 11, 2019, 12:45 PM

#

I'm not looking for exact steps . . . just a general overview/best practices

#

Yeah

clear igloo Oct 11, 2019, 12:46 PM

#

Then, depending on the design, you would assign a DHCP server per each sub-interface on pfsense which corresponds to the vlan I believe

austere scroll Oct 11, 2019, 12:46 PM

#

Robsch . . . you've been typing for a while now, making me nervous 😂

clear igloo Oct 11, 2019, 12:46 PM

#

But you mention unmanaged switches, are you just grouping the switches without actually doing VLAN tagging?

austere scroll Oct 11, 2019, 12:47 PM

#

Would an example sub-interface be the parent LAN interface?

radiant crane Oct 11, 2019, 12:47 PM

#

@austere scroll lmao

#

I was typing up something for @waxen scroll

#

But I just DM'ed him

austere scroll Oct 11, 2019, 12:47 PM

#

My switch configuration is very basic tbh

#

But i can see that the VLAN has a tag of 1

clear igloo Oct 11, 2019, 12:48 PM

#

A sub-interface is dividing a physical into multiple logical interfaces based on VLAN. If you're just grouping the switches and plugging them into different physical interfaces on pfsense, then you would just do it on the physical. Assign the gateway IP to each physical interface in PFSense and then have it do a DHCP per interface

#

So if you had:
PFSense----Group/Switch A
|
Group/Switch B

Then assign a different IP address/subnet for each interface on PFSense and setup two dhcp scopes

austere scroll Oct 11, 2019, 12:51 PM

#

That's what I was thinking, so for example:

PFSENSE
|
|
WAN
|
|
LAN (192.x.x.x) via DHCP
|
|
VLAN 1 (10.x.x.x) via DHCP

#

Is this correct?

clear igloo Oct 11, 2019, 12:51 PM

#

Only if LAN is tagged with VLAN 2 or something else

austere scroll Oct 11, 2019, 12:52 PM

#

I see what you mean

clear igloo Oct 11, 2019, 12:53 PM

#

Well, I guess it depends, if there is no VLAN tagging on LAN and the LAN
switch will pass tagged traffic then technically it could work like that

#

untagged could be put in a different VLAN

little schooner Oct 11, 2019, 1:45 PM

#

@clear igloo that reminds me, I tried having a non-subinterface setup with the Edgerouter and I could never get it working. Packets kept saying they were Invalid, retransmitted over and over and never was able to ping outside network.

Once I enabled subinterface mode on just one Edgerouter port, suddenly everything started to work. I was reminded never to buy hardware with beta software after this experience

not much of a person who dwells in the networking world, but thought id dip my fingers in a little,

dunno if this is much of a basic qustion, but is it worth flashing your routers firmware, if so which one to pick from? what are the benefits?

DD-WRT
openWRT
Tomato

waxen scroll Oct 13, 2019, 2:22 PM

#

Honestly, the gain is very little unless you're an advanced user. The router still works the same, but you are presented with about every option that should be tweakable but isnt in the factory GUI. Most likely you wont do anything more than you do now except have more pretty screens to look at.

#

I personally have used DD-WRT and can recommend it

#

no harm in installing it with no goals.... click around and maybe ideas will come to you

Personally, DD-WRT works if you need to replace a provider box that uses a different VLAN such as Google Fiber

craggy parcel Oct 13, 2019, 4:14 PM

@thick minnow If your router is still under warranty, you should NOT flash it with anything but original firmware, as doing so might make warranty service problematic. Also, unless you need an additional feature in your router, I'd say it's not worth it.

If it's a router/modem from your ISP then flashing it is almost always out of the question

thick minnow Oct 13, 2019, 4:19 PM

#

ah,

#

guess ill leave it be,

#

@clear igloo and for comcast, isn't it illegal to do?

#

Since the modem is part of the combo unit

clear igloo Oct 13, 2019, 5:20 PM

#

Maybe not illegal, I don't think, but more ToS breaking at least and you'll definitely get your butt taken to court

little schooner Oct 13, 2019, 5:20 PM

#

Oh right. That's more accurate

clear igloo Oct 13, 2019, 5:21 PM

#

There might be a law against it, probably tampering with non-owned devices or something, but I can't say for sure

valid tapir Oct 13, 2019, 8:29 PM

There probably is

Just got rid of my tp-link consumer gear and went enterprise gear for under £1,500 if you're interested in what I got I made an amazon wish list
https://www.amazon.co.uk/hz/wishlist/ls/RQ1OKPMB23XR?ref_=wl_share

Check out my list on Amazon

#

And i just set it yo now

little schooner Oct 13, 2019, 9:56 PM

#

Ubnt is enterprise lite. Enterprise stuff is like enterasys, rukus, Cisco, Aruba, etc

i'm planning to buy a 30$ dell optiplex with pfsense to replace google fiber because their wifi router and vlan translator is terrible (the modem is seperate)

waxen scroll Oct 13, 2019, 10:02 PM

#

i feel like that would be worse

#

how fast is google fiber

sterile pasture Oct 13, 2019, 10:03 PM

#

1gb technically

#

The wifi cuts out constantly though

#

DD-WRT worked on a test router that cost 6$ to bypass the router

waxen scroll Oct 13, 2019, 10:06 PM

#

well, let us know how that goes. i know ive seen gigabit tax a laptop CPU and im sure an optiplex is not much better if its a crappy little dual core or something

sterile pasture Oct 13, 2019, 10:07 PM

#

the processor in the normal router can't be very fast anyway

#

I think the main issue will be finding a decent PCIE wifi card

waxen scroll Oct 13, 2019, 10:07 PM

#

i believe the router is mostly processing using an ASIC

sterile pasture Oct 13, 2019, 10:08 PM

#

its kind of an ASIC, however it is included in the ethernet chipset

#

i might start after folding month because one of the folding computers might be a fine router and I don't think OpenBSD goes well with Ubuntu

hollow marlin Oct 13, 2019, 10:56 PM

#

ASICs are made for one task. A folding ASIC will not know what to do with routing

#

ASICs in the ethernet chipsets dont do anything other that packet processing. Routing and switching are all CPU in all non-router hardware

sterile pasture Oct 13, 2019, 11:49 PM

#

Folding Asics are gpus

hollow marlin Oct 14, 2019, 12:20 AM

#

Still useless for routing

#

GPUs are also not ASICs

sterile pasture Oct 14, 2019, 1:15 AM

#

They haven't made any asics for folding yet, and it seems like a gpu wouldn't apply to routing anyway as the nicer consumer home routers have low-end arm CPUs

#

i'm just going to see what happens

little schooner Oct 14, 2019, 2:00 AM

#

@waxen scroll not sure how I would even test 1gbps with a 4790k pfsense system. I want to see what are the limit of all-cpu routing

#

In something like that

#

Unless it has already been done somewhere... I should probably Google first

sterile pasture Oct 14, 2019, 2:17 AM

#

As far as I can tell, the CPU is usually used for routing

little schooner Oct 14, 2019, 2:59 AM

#

I found one link on negate community forums

#

And it's not all that great for 4790k

hollow marlin Oct 14, 2019, 4:37 AM

#

@little schooner I thought 1gig was pretty easy to hit with pfsense?

pseudo blade Oct 14, 2019, 4:56 AM

#

@hollow marlin GPUs are apparently excellent for routing.

#

I remember a research project done on the matter. I think they called it "packet shader"

#

GPUs are ASICs, it's just that their "application" is "do all the stuff necessary to render stuff".
