I have a 27 inch screen 1440p screen and I hate it. Its way too big. My 24 inch screen is also 1080p which is dreadfully low res compared to my laptop's 19 or whatever inch screen at 1440p.

If I had two secondary screens that were 24 inch 1440p I'd be very happy.

We spent more than twice the value of my house on bullshit machine learning blackbox ddos mitigation devices that I currently have in passive mode doing nothing because I don't trust them to not be invisibly loving up everything.

Buying these things were almost certainly the worst mistakes we made when building out a datacenter. We could have purchased 50gbps of bandwidth for 5 years for what we spent on these loving things.

Several times these things have caused horrible horrible impossible to troubleshoot cascading failures. For example, something goes wrong so logging spikes. The spike in logging triggers some ML horseshit to start invisibly dropping traffic to or from AWS (because thats where our logging services were hosted) because this spike of traffic is an anomaly. Same for DNS

What happens when logging traffic or DNS gets dropped? Obviously you send more to log the failure to log or request DNS again.

Never again.

Could you lower the sensitivity so it would take a disaster-level ddos to trigger action?

Or whitelist your cloud service IPs and DNS forwarders so it doesn't interfere with business traffic?

No*

tldr
A huge amount of our traffic is UDP and my WAN traffic is very asymmetric. There is zero way that I can enforce that traffic exits through the same ddos appliance that it enters. This means it is impossible for these things to have any meaningful view of what UDP traffic is actually doing, and TCP traffic insight is reduced. Also unless I whitelist all of amazon's blocks which is pretty close to removing the device from service entirely like I have right now, I can never guarantee that IPs are going to be within a given whitelist. DNS whitelisting isn't a thing. The way the thresholds are generated, if an IP suddenly moves it will almost certainly immediately be flagged as anomalous and almost certainly blocked until a human intervenes because log transmission is continous and will look like an attack.

Ultra simplified view

wan1 -> ddos1 -> network |
wan2 -> ddos2 -> network |


The real answer to ddos mitigation is don't even remotely try to do it yourself. Properly harden your nginx or haproxy instances to flush their connection tables as necessary to avoid the low hanging fruit. If anything volumetric happens, pray that you chose a provider that supports bgp community strings to blackhole traffic then use that and the source is something that is reasonable to blackhole, not the entirety of comcast or something. Anything more serious of a problem or larger scale than that, you need to do bigger things like have a geographically distributed presence and do fancy things with BGP any casting and using sacrificial sites

I have a hard time believing a device bought in the last 5 years can't properly handle what you're asking of it.

But fine, you somehow do. Buy a used Fortigate 100d and FortiGuard license for like, 2000 dollars altogether on ebay and use that.

But fine you can't afford that. Then buy an off-lease piece of poo poo dell server on ebay for 350 dollars and put pfSense on it. Hell, buy two and put them in active-passive with VRRP.

We talked about it both from a technical and marketing perspective and eventually came to an agreement on how things would be done and the timing of the changes. Adding a domain to the server and dishing out some aliases is not a big deal.

At the very end of the conversation I identified a serious problem. I expect you all can guess what it was.

A few years back I helped a certain video editing software/hardware company when they moved offices and discovered they had a shitload of high end parts and equipment around that was still very valuable but was not needed/useful for any of the hardware they currently built. In the process of helping them sell that stuff, we figured out they had easily several hundred thousand dollars across all this poo poo that simply hadn't been tracked and was laying around.

Some of it was even stuff from back when the company was founded, but was still quite valuable and interested buyers were easy to find for it. And none of it would have ever come back if they'd not moved out of their old office floor .

That's interesting because old computer equipment normally decays at about the same rate as bananas.

Oh poo poo. Stuff is about to get exciting.

Just had a talk with HR. At 3:45 they are firing someone who is 'known to get verbal and or physical'. I can think of a couple people out in the production floor that would fit the description, but they all go home at 3:00, so it has to be someone from the office.

So here's the floor layout:



They are going to bring the person into the conference room to sit down and talk. At that point they want me to go out to the front desk (the IT office is right by the front desk), get the lady that sits out there, and bring her into the IT office and close the door. Then I have to make sure the mystery person doesn't 'escape' or something and walks straight out the front door after they fire him.

Don't try to give a VM more than like 8 cores at a maximum ever. If it needs more than 8, it needs to be a dedicated piece of hardware.
Also unless there is a licensing concern, give things 8 vCPUs each with 1 core and not 8 vCores on one vCPU.

JB's talking about his new house, and punching down infrastructure cables to patch panels. Are you seriously suggesting he run premade patch cables through walls and direct connect to computers on one end and his switch on the other? Just because it's a house doesn't mean you have to treat it like rocks and trash you need to sweep up.

A bit rude.

I missed the part about it being for a house and assumed it was making custom length cables for a DC. I'd still suggest using these types of keystone in your wall plates and premade cables rather than doing it yourself.

As far as deprioritizing, they’re probably tired of a not insignificant amount of traffic generated by gamers and games themselves with “latency meters” that are running all the time.

Blocking ICMP is used to make network reconnaissance more difficult. It’s not always that effective at that, but it does help agains low-effort script runners. It also stops traffic external from their networks which also helps in reducing resource consumption.

I’m not saying the bulk of traffic is ICMP traffic, but it’s also not flying under the radar in terms of usage either.

I was under the impression that any sort of embedded game latency count is going to be application level udp, not icmp.

Like I guess ICMP is an amplification vector but I'm still curious what actual percentage icmp reponses, or unreachables could possible represent. Are we talking 0.1% per 100gbps? 3%?
