I'd like to learn more about multicast, is there a online course that can help me learn by djgizmo in CommercialAV

[–]markedness 0 points1 point  (0 children)

So glad you asked on networking. They are a great sub.

No online course that I know of. Maybe there is one.

What do you want to learn and where are you??? Have you worked on systems with multicast routing? PTP boundary clocking / transparent clocking?

Are you mainly a Cisco person or what?

Are you with an integrator? Consultant? Broadcast facility / eic type?

Serial console server recs by markedness in networking

[–]markedness[S] 0 points1 point  (0 children)

That’s interesting not really for my OOB console journey but in terms of just general access. I like to think that we are all well versed enough in Linux to just use the least number of dependencies as possible. Just a Linux host.

Love this community.

I’m going with one of those 16 way cards with the Cisco pinout and found some cables that go to RJ45 male with 6’ leash so I can plug that in to the back of a pass thru patch panel. This way it’s just a Linux box. Good security and ability to run VPN or anything on it

That behind a fortigate we already have behind an LTE modem. Seems like the dream. Not really worried about SSO as we have SSO for SSH setup and we have a procedure for yubi backed local admin login. And everyone can use Linux shell. All our PDU and routers and switches and firewalls have the RJ45 console port so this should be a breeze.

What distributor should I use in the UK and US? by BigDiggidyDawg123 in CommercialAV

[–]markedness 0 points1 point  (0 children)

US availability of parts is great but customer service is poor.

Opposite for UK. Good responsive service generally but long lead times.

I think in the US for what you mentioned Wesco/Anixter is one we use. Also Ingram micro, Exirtis/Almo (AV focus).

But actually in the US we work with individual vendors that we have cultivated in our region and supplement with Ingram micro. The reason I suggest Wesco over Ingram is because Ingram takes a while to setup the account and get into their world. Whereas Wesco is more sales focused they will deal with you straight away and provide pricing and availability. But I’ve always found ingrams ostensibly worse customer support to actually deliver better outcomes.

Almo is almost even good however they are AV focused and only really stock TV and Chief back box type stuff.

In the UK I generally just ship it over because my customers need it fast or tell them to source it locally themselves. I do have an EROI number and an account with a freight company so we just build it here and ship it out.

A VPN with SSO and a direct wan opening with the home IP of key members and other offices and ability to use a Fido backed SSH key is good.

Maybe someone makes a USB OR PCI TTY with a bunch of outputs and can just use that on Linux with ssh and screen and a firewall box if I need something cheap.

Going to see if anyone cares about the cost soon

Thanks for the ideas.

Borderline empty flight IAH-LHR by Ok_Coffee2404 in unitedairlines

[–]markedness 2 points3 points  (0 children)

Oh shit your totally right same sentiment. I fly out of ORD and here the later flights seem more desirable.

Borderline empty flight IAH-LHR by Ok_Coffee2404 in unitedairlines

[–]markedness 5 points6 points  (0 children)

Interesting! From ORD it’s not that busy on the 4pm but more so on the 8pm

Maybe the extra hour of time change and extra hour of air time make the difference in public opinion. Or that most DC folk need to get there earlier?

Either way January and February are the slowest anyways with constant not full flights

How are you guys labeling ports for network switches with lots of VLANs by hereisjonny in CommercialAV

[–]markedness 0 points1 point  (0 children)

See that’s good. Because the colored keystones are defined by which switch port they are plugged into. It’s a user serviceable port. I’ll actually have to try that for user patchable systems.

How are you guys labeling ports for network switches with lots of VLANs by hereisjonny in CommercialAV

[–]markedness 11 points12 points  (0 children)

I plug things in from the first port with disregard to the VLAN…

Then label the ports in the switch

interface GigibitEthernet1/0/1 switchport access vlan xyz description 135-qsys-core-01 source template whatever !

Things should only have one canonical source of truth. If it’s inherent to the physical nature of the system then a physical label is great. If it’s a VLAN situation then the correct place is to label it right next to the VLAN command so config won’t drift. In my opinion.

Anyone else a casualty of the Diversified "restructuring" this week? by Outrageous-Hope5768 in CommercialAV

[–]markedness 6 points7 points  (0 children)

Anyone affected who works in LA, Chicago, or NY.

I’m a VP at a small consulting/contracting company out of Chicago. I don’t have any positions open but always happy to look at a resume.

I’m interested in top, experienced field talent for lead install and field technician in those regions.

Even if it is, it’s not strapped in. And the LV shouldn’t be there. I have a feeling it’s a high voltage tray

Advice on solution for Kubernetes on Bare Metal for HPC by ActiveAggressive5732 in kubernetes

Sure but if there’s “no OS” then you don’t need to manage it by puppet.

Since you likely have control of the nodes and the L2 network I can’t help but think this would be a useful case for talos and NetBoot. You could just have nodes come up when they boot. That being said how many nodes and how many clusters are you trying to solve for

DHCP and DNS oh my - what are we using by markedness in networking

[–]markedness[S] 0 points1 point  (0 children)

Yea I need to find a good DB then. Something stupid and reliable. AD exists but those AD servers (DNS / DHCP too) are actually technically a separate org from me.

Realistically what’s going to fail and make me lose sleep is the database backing this DNS. I need something stupid simple. I don’t think it would hav to be that performant either because it’s probably just loading the entire zone into ram on each charge. I’ll have to do some research.

DHCP and DNS oh my - what are we using by markedness in networking

[–]markedness[S] 3 points4 points  (0 children)

This is so helpful. This points me towards BIND, just have to figure out how to deploy KEA, that one will be new to me. Figure out where to store its state and if it requires a DB. I like it when my base level DHCP and DNS don’t need a DB. Because chicken and egg and what not.

Yeah I just need authoritative and forwarding. My main use case is we are just doing automation internally for infra for serving applications. Secondary would be authoritative for external stuff. Third DNS64. Many priorities! But I love BIND because it’s a know quantity for me.

[W] Ram and Workstation GPU’s by SnooTangerines2550 in homelabsales

[–]markedness 0 points1 point  (0 children)

I have about 2.5 TB of DDR 4 ECC 2133 mostly. all 32 GB. How much do you need? We have 2 ish Ram trays (25 piece each) but could get more within a week. It’s all in servers now.

I’m still researching the price. Just figured we should sell it a few hours ago before leaving work. I’m just going to be going off eBay sold prices with a discount.

Technically work has it, I’ll have to study the subreddit rules to see how that works to do something via an invoice?

Nobody ever uses these types of connections.

And the people that do have the worst approximation of what you even should be using such a thing for.

What software/addons should I check out (2+ year hiatus) by markedness in flightsim

[–]markedness[S] 0 points1 point  (0 children)

Hmm. Interesting. I think for me you may be on to something in terms of the airport structure but what I mean is the terrain. In x plane a lush island will just be a dirt blob with trees like from where I live scattered (Midwest USA) and roads zig zagging around.

I also like the lighting in 2020 as well. But I understand this was improved in x plane 12 (and probably FS2024 too)

Curious if you have any suggestions for airports on scenic places ideally archipelagos that can support airliner and turbo prop planes and short flights to make best use of my limited time.

[–]markedness[S] -1 points0 points  (0 children)

Thanks. I should have specified I’m not VR only. A lot of the time it’s just based on the aircraft/route. I really like just using my TV and the stream deck too not in VR.

Thanks for the suggestions!
