I did as well. Probably my first introduction to programming though I usually tell people that my experience with Java was my first programming because visual programming is not "real" progamming

the same organization that does the FIRST tournaments for lego mindstorms has a program called FTC (first tech challenge) for highschoolers and you can get a college scholarship to a lot of schools if ur team does well enough

Bye!

little schooner Mar 3, 2019, 3:32 AM

#

Is this good practice for opening a port on a server to the outside?

Internet folk to port 6981
     ---> PFSense WAN interface Allow port 6981 FROM US traffic only
      ---> NAT source traffic with new destination of server in DMZ
       ----> Hit server with ufw enabled for port 6981 only
         ---> users reach service

fresh copper Mar 3, 2019, 3:33 AM

#

That sounds pretty decent

little schooner Mar 3, 2019, 3:34 AM

#

So it wouldnt be necessary to do something like checking if source ip is trying to make a connection 5 times in a row (basic dos)?

fresh copper Mar 3, 2019, 3:38 AM

#

It depends on the service. If it's an end user service then there could be multiple devices behind the same ip that randomly decide to all connect at once. If that would never happen then consider how often you would expect requests from the same IP. Maybe some services you only expect once an hour at max so you set no more than two connections from an IP on any given hour. Maybe it's something where you expect to only have one connection from an IP at once even if there are a lot of packets once connected. Maybe it's something where it's password protected so you ban IPs that have too many failed attempts.

little schooner Mar 3, 2019, 3:39 AM

#

Hmm, I think it will be password protected. It is basically an ethical hacking game server

#

it supports login and they will need it

#

so I think I might do it via failed login attempts then

fresh copper Mar 3, 2019, 3:40 AM

#

That's the best idea

little schooner Mar 3, 2019, 3:40 AM

#

Also, I know it is not going to be an updated appliance that we are publishing

#

chances of it getting compromised are low though?

#

if we safeguard the ports, and change root username

#

root password*

#

disable root login even

#

It is a ubuntu 18 LTS instance

fresh copper Mar 3, 2019, 3:42 AM

#

Chances of any small target getting compromised is low but even a low chance could happen. Best thing to do, consider cost of putting in the security vs cost of being compromised times the chance it will happen. If it's easy to put in extra security, it might as well be done even if it is not strictly required

little schooner Mar 3, 2019, 3:43 AM

#

I think it would be easy since we do have some documentation to take us through the steps (with some tweaking)

#

but it will be inside a VM where it keeps other production esxi servers

#

but since it has different IP and all, it should be safe?

#

We do keep esxi updated at least

fresh copper Mar 3, 2019, 3:43 AM

#

People always think that things should be safe until they suddenly aren't

little schooner Mar 3, 2019, 3:44 AM

#

I try to make it safe as much as I can. But my professor wants to just throw it up there without

#

doing the security part

#

I try to make the case to him that we should secure it better before implementing

#

So the service will run in a VM whose IP can contact no one else internally

#

only the internet connections

fresh copper Mar 3, 2019, 3:46 AM

#

I guess it depends on how bad it is if it is compromised. I have little security on most of my servers but I also have nothing of importance on them and no connections to things that do. It sounds like your VM is essentially isolated where it could not do harm even if it wanted to so it's probably not a big issue.

little schooner Mar 3, 2019, 3:47 AM

#

Alright, so it looks like the plan I currently propose may just work for us fine

#

yeah we will snapshot the VM and restore if necessary

#

Now wait, if we start getting hammered with internet traffic and the router cant handle it, that just means we need to investment in some newer equipment?

#

newer as in faster?

#

I was reading online that ddos protection is only as good as the hardware in the router

fresh copper Mar 3, 2019, 3:50 AM

#

Depends on where the bottleneck is. If it's in equipment you control then yes, otherwise you can't do much than hope you can cache or go serverless. Cloudflare makes some good points of DDos mitigation in their article https://blog.cloudflare.com/how-to-drop-10-million-packets/

The Cloudflare Blog

How to drop 10 million packets per second

Internally our DDoS mitigation team is sometimes called "the packet droppers". When other teams build exciting products to do smart things with the traffic that passed through our network, we take joy in discovering novel ways of discarding it.

little schooner Mar 3, 2019, 3:50 AM

#

thanks for that

#

He cant wait to get this up and running because he wants to have ethical hacking competitions with other schools

#

@fresh copper Have you worked with esxi before?

fresh copper Mar 3, 2019, 3:53 AM

#

Unfortunately, I have not

little schooner Mar 3, 2019, 3:53 AM

#

Oh. I did have an additional question for that but

#

no worries its fine

fresh copper Mar 3, 2019, 3:54 AM

#

Also, ethical hacking competitions are so fun. CTFs and stuff like that

little schooner Mar 3, 2019, 3:54 AM

#

Yeah this game server keeps score and starts the activities for students to play and work with. they can be on teams and all. They will have a great time i just know it. It is capture the flag-based. Basically i've helped my school take their lab up to the next level and bring these capabilities (finally) after 5 years of dealing with sub-par performance and lack of server-anything

#

The IT department does not show love to the cybersecurity program unfortunately. My professor is really the only one that can deal with the things that go wrong in the classroom

fresh copper Mar 3, 2019, 3:56 AM

#

I can imagine that

little schooner Mar 3, 2019, 3:57 AM

#

I came along in the picture in like 2014, but they had these issues for the longest time

#

in fact, they started the cyber security program because of the lab improvements done

#

before the classroom had no computers on the desk

#

it was strictly lecture room

#

Now all of a sudden, the school is getting thousands of dollars from the many students enrolling to take the degree program

#

In the end, its good change and to the advantage for the students, which makes me happy.

#

@rocky badge I have a question for you about esxi

little schooner Mar 3, 2019, 5:50 AM

#

If a vswitch is created and the VM is using an adapter within that vswitch with an ip block of 172.16.x.x, is it possible for something like PFsense to forward traffic to 172.16.10.10 (the VM) by making a static route to the Esxi system that holds the VM (192.168.1.50)?

would Esxi be smart about it and forward it to the vswitch internal network?

hexed vault Mar 3, 2019, 11:53 AM

#

@little schooner I'm not sure for esxi, but if the 192.168.1.50 is the hypervisor itself - it shouldn't. That would be mixing up control plane and userplane.

waxen scroll Mar 3, 2019, 1:29 PM

#

At the very base the answer is no

#

Esxi only operates at layer 2

#

I believe with the add-ons there's a potential it can but I'm drawing a blank on what the add-on is called and it costs way more

#

It's called NSX

thick minnow Mar 3, 2019, 2:20 PM

#

Hey guys, I’m back. What’s up?

#

Ethical hacking sounds fun if it’s done properly and ethically.

#

The thing is, ethical hacking is like another art/skill form, there are quite a few ways to accomplish a task. Ultimately, there is no perfect way sometimes.

#

However other times, there is only a certain way to do things in order to achieve a result.

#

That’s the fun of it, experimenting is what will ultimately give you experience.

I'm really going to see what the best affordable options are and see if I can even convince my parents to cut the landline phone as well.

Currently my family has bundle.(TV,Phone,Internet) and I think we're paying something like ~$200 a month.

i pay nearly that for just tv/internet

I know it sounds like my family is rich, but were not. I'm personally not that type of guy that is "flashy" or always has to have the "latest and greatest.

I really am going to talk to my parents about cutting a lot a stuff we don't need.

ive debating cutting the tv out, saves like 100$ a month

Xfinity Package: $144.99

#

Gigabit is around the speeds of a HDD

thick minnow Mar 3, 2019, 5:52 PM

#

youd love 300/20 then

#

So it's just the size of potential throughput that makes Gigabit appealing to companies that need to move large amounts of data even if it means slower speeds?

most of the time gigabit is all they can get

What does it mean by VLAN group and what does it mean by members?

But what does that mean? Arent they all local ports?

There are exactly 4 ports that you can plug a cable into them

I did not setup any "groups" of ports

that is why this is so confusing

so members doesnt mean vlan tags?

#

heres one im dealing with now

#

Business unit decides to push their [important complex application] to a managed service provider

#

they argue on how the provider can ensure SLAs on the network and decide "the vendor needs to take 100% responsibility, we're hands off"

#

so the vendor orders two MPLS circuits to each datacenter of ours

#

well geniuses decide after the contracts were signed "wait, it costs how much?! ...and... you cant see into our own network anyway?"

so now they decide we need to order our own MPLS circuits on our side and share a VRF with the vendor who buys the circuits on their own side

uhh you can enable telnet on your gateway first and then use a program like PuTTY to connect to it by ip address

it will prompt for username and password, and you type it in

they got bought by riverbed but at two past jobs they put tiny as fuck opnet agents on all computers, including servers... someone like me could go in at any time and tell the agent on the machine to start capturing packets and record them locally so i can download later. that way you never had to walk a user through a wireshark or be desk side. you can also start/stop in mass so you can get all of the machines you need captures from sort of synced up

so going back to that color screen

those are actually thousands of arrows

if you zoom in, they're little arrows

says what direction the individual packets were flowing

so if you layer many capture points in that graph, you can see where a drop might occur

zoom all the way in

that's a neat function

#

waxen scroll Mar 5, 2019, 11:34 PM

you dont need to look for a drop, it will crunch packets and flag in there where the drop or retransmit was seen

and you can keep zooming until you get where you need

#

selecting an arrow will select the packet and you can open a wireshark-like view to see it

waxen scroll Mar 5, 2019, 11:39 PM

#

so basically this is a bulk AF app that consumes a ton of CPU and ram.... so the goal is when a user has an issue... port health -> netflow check -> metadata check for packets stored on taps -> download tap data and/or capture on user PC -> the app i showed

#

the app is for when you identified what you want to look at

#

you dont want to feed it too much

#

ive seen it eat 32gb ram no problem

#

with a capture file of like 2gb

#

one other neat thing is the delta time.... when the app smashes captures you get real delta time between machines

#

not the one sided delta wireshark gives

It’s funny seeing how even basic job searches for IT jobs require 4-5 years of experience.

#

??? What do you expect a kid from college to have?

#

Lmao

#

Companies should at least be willing to provide internships or at the very least a training/testing period to see if you qualify for the job.

waxen scroll Mar 7, 2019, 5:38 PM

#

i'd argue that those might be worthless too

#

based on what ive heard and if you look at r/sysadmin and r/networking, interns do very little

#

mostly document

#

document is a good skill but how do you move on after internship if all you did was document

thick minnow Mar 7, 2019, 5:39 PM

Hey, at least in your the field right?

waxen scroll Mar 7, 2019, 5:39 PM

idk

#

i lucked out, i was doing DCops and some company was hiring for contractor network admins and their standards to entry were low

#

the company was a massive well known company in their space

#

so the network was huge

@waxen scroll ?

#

Is it true that there must be a username specified SOMEWHERE if you are logging into a system via SSH using public key authentication?

#

You can't specify a private key and expect it to connect you automatically?

waxen scroll Mar 8, 2019, 12:04 AM

#

i dont think so

#

last time i set one up it let me right in

#

obviously in the system itself its setup per user

little schooner Mar 8, 2019, 12:06 AM

#

I have it setup in pfsense, the public ssh key is for user admin

#

but then when I open putty and connect, it asks for a username

#

this is on windows. And until I type in "admin" then it connects using the private ssh key

waxen scroll Mar 8, 2019, 12:07 AM

#

you have to make a session profile in putty and then attach the stuff to it i think

little schooner Mar 8, 2019, 12:07 AM

#

Yes, there is a setting to attach the auth key (ssh private key)

#

but i can attach username to it as well?

waxen scroll Mar 8, 2019, 12:07 AM

#

shouldnt have to

little schooner Mar 8, 2019, 12:07 AM

thanks for your input though

chrome hound Mar 8, 2019, 12:29 AM

#

I haven't used an ssh server that doesn't require you to pass a user, how else would it know what pub key to auth you against?

#

and you can set the user in putty so it won't ask for it

#

its under connection > Data > Auto-login username

little schooner Mar 8, 2019, 1:28 AM

@chrome hound thanks for that

Can you reccomend me good bulk cable and good keystones

That can do 10gig

clear igloo Mar 8, 2019, 12:54 PM

#

Any non-CCA Cat6 or Cat6A cable and keystones will do for the most part. Monoprice is usually good

pseudo blade Mar 8, 2019, 2:22 PM

#

CCA AKA category binworthy.

pseudo blade Mar 8, 2019, 2:43 PM

#

It's not Cat5/6/etc. if it's CCA.

omg nothing I did would accept the Certificate

#

Microsoft forget to add that you need Domain Enterprise permissions to add Subordinate CA

I wasted like 4 hours

I have no idea what you’re talking about, but I’ll agree anyways.

#

oh, CA means certificate authority. it's the thing that issues computer certificates. certificates identify computers and prove their identity cryptographicly

#

it's like a badge

#

computer get certs from a server computer that issues it to them

Just keep working hard at whatever you’re doing, and it should eventually pay off.

Oh okay. I was confused there

so the box would say it's non CCA?

Usually they will say CCA on the box so if it doesn't then you're good

#

How about this: is there an extra step when installing Cat 6a cable?

#

the shield part?

#

I saw in videos there is like an extra piece of plastic to attach

clear igloo Mar 8, 2019, 3:12 PM

#

There is a plastic bit in the middle but it doesn't attach to anything, you just cut it off to fit the wires into the keystone

#

You're talking about the plastic shield in the cable itself?

little schooner Mar 8, 2019, 3:12 PM

#

Yeah, if I wanted to make my own cable with it

#

not put it in keystone

clear igloo Mar 8, 2019, 3:13 PM

#

Yah, when I did mine I just cut it to the edge of the cable so only the wires were exposed

little schooner Mar 8, 2019, 3:13 PM

#

and then at that point it's the same as cat5e making?

clear igloo Mar 8, 2019, 3:13 PM

yup
