  1. Distributing Video Feed via LAN

    A more hardware-centric way of doing this is "AV-over-IP" which ahs two main standards right now: HDBaseT-IP and SDVoE. You can read more here: https://www.cepro.com/article/hdbaset_ip_vs._sdvoe_smackdown_av_over_ip
  2. what happens if you try to telnet or SSH to the iLo IP?
  3. Best Ethernet Adapter for Fibre Optic?

    TP-Link is a brand that makes almost everything. And Fiber can mean almost anything - do you need a product with an SFP so that you can attach directly to fober, or just a router that will connect to an ONT via ethernet? And what is your definition of “best”?
  4. You say “several restarts and shutdowns” but did you actually disconnect the power for an extended period of time, at least 30 seconds? Since the iLo is always on even when the main system is shut down, the only way to restart it is to complete unplug the power supply(s).
  5. can't connect to main routers

    What do you mean by “main router”? What does this router that you’ve shown in the screenshot do? Where is the router, and is it a physical RouterBoard, or a CHR, or an x86 install?
  6. All IPMI/BMC systems are susceptible to crashing. They are just an extra computer (usually some variant of an ARM CPU) that is on the same motherboard, and they run their own OS (usually some form of Linux with Busybox). About a week ago I had to remotely restart the IPMI on an AsrockRack motherboard because although the WebUI was working, the iKVM wasn’t. Dell DRAC, HP iLo, Asus ASMB, and any other similar product are really just the same thing.
  7. I’m guessing it isn’t possible to power cycle this server? Have you tried connecting to iLo via SSH? You may be able to reboot the BMC if you can into it that way.
  8. Whats a good place to buy bandwidth in bulk?

    There are two ways to buy bandwidth in bulk. Contact local fiber providers and get “fiber DIA”, or buy DIA at a datacenter. The lowest prices I’ve ever seen were from GTT at the Equinix DC2 datacenter - although this still required renting space from Equinix, paying for a cross connect to GTT, and buying a transport circuit from another provider to reach where we wanted the internet. For large amounts of SLA bandwidth this comes out cheaper than DIA from the local fiber providers. You can’t buy bulk internet without an SLA. That “lowest price” I said above was still over 40 cents per Mb (exact prices are private and vary). Noone will sell bulk internet otherwise. And also, this will require you to use BGP, so you’ll have to learn the basics of that.
  9. Compress all traffic with VPN

    He said it was like dialup... could be a very low tier satellite connection, or whatnot. OpenVPN can do compression and has a few different types available. Mikrotik routers can supposedly do compression in a few different ways for both local (between two Mikrotik devices) and VPN traffic but I haven’t played with it enough to get it working, for my use cases at least. No matter what you are using, it should be noted that any encrypted traffic, like HTTPS, is essentially uncompressible, and some algorithms like LZO can actually increase the data transfer size when used on such data. EDIT: two non-vpn things to look at are http://wanproxy.org/ and http://the-toffee-project.org/
  10. Move micro atx mobo to server rack

    That’s about 450mm (463 to be exact). You’ll have to browse around for “short depth” chassis that are max 440mm / 18” deep (remember to account for wires out the back)
  11. Move micro atx mobo to server rack

    How deep is the rack? That will limit the rackmount chassis that you can use. If it’s 600mm deep I like the SuperMicro CSE-813MTQ (just barely fits in a Navepoint 600mm rack, have to use a right angle power cable) and the Norco RPC2304 (about 500mm deep IIRC). If your rack is 450mm or less then you’ll need a chassis that don’t have front accessible hard drive bays, SuperMicro has a few 1U choices in this area.
  12. the default config is as a normal switch. The only ones I know of that aren't like this are Quanta and similar white-box switches, where you actually have to load an OS onto them in order for the switch chips / ASICs to be activated. just be aware that like Cisco and other companies, HP switches only like "HP" SFPs. We use HP compatible ones from fiberstore.com at work.
  13. Well thanks for the report, I’ll have to try that card. I do wonder though if any of your issues would be different for me, I use Proxmox.
  14. I had assumed you would have an LDF at both ends when I tested the Link Calculator. You at least need some sort of directional antenna at both ends, but best results come from having similar equipment at both ends of a link.
  15. If you already have 1m satellite dishes, then you can use this: (Mikrotik LDF 5) https://mikrotik.com/product/rbldf_5nd - I used the link calculator set to a distance of 0.2km, and it says that a 450Mb/s link should be able to be reliably achieved. Ubiquiti might have a wireless radio that is meant to use existing satellite dishes, but I don't follow their products, just Mikrotik's. If you want to look for other PtP products including ones that are 802.11ac, then you can look here for Mikrotik https://mikrotik.com/products/group/wireless-systems and here for Ubiquiti https://www.ubnt.com/products/#airmax
