@Mario-Jakovina said in Recommendation for home WiFi router:

Hello everybody!
(I'm sad to see Mangolassi dead, but here is a topic from me)

1. Can you give me some recommendation for new home Wifi router?
Here is description of my "system":

• internet link is 300/30 Mbps
• 15 devices should be connected to it (6 phones, 4 laptops, 3 TVs, one WiFi access point + occasionally ,some guest or our HTPC
• of these 15 devices, 3 should be connected via LAN (2 TVs, one HTPC), others via WiFi

Reason for buying is that my internet provider changed the router type (after upgrade of speed from 200/20 to 300/30, but this new device seems to struggle with the load).

2. Is there some Mikrotik device that you would recommend for this? (we have good local Mikrotik dealer here)

3. If I put telecom's router in "bridge mode" and put better router behind it, is it reasonable to expect that the telecom's router's should not be a noticeable bottleneck (or not as much)?

Thank you

I'm not sure which MicroTik routers would be a good fit.

We use a lot of the Netgate/PFSense routers at work, and I've been impressed with the price/performance of them. If they're available in your area, you should look at a Netgate 2100 for your needs.

Once you have the ISP router in "bridge mode", it should cease to have any performance impact at all. Even the cheapest devices can forward traffic at line speed these days.

While I was attempting to look up how to backup a Proxmox host to a remote Proxmox Backup Server over Zerotier, all the instructions I found were very complex. While those instructions are true if you want to route an entire network, it is very easy to get a single Proxmox host and single PBS server connected over Zerotier.

1. Join both host and PBS to the same Zerotier network
2. Add 2 routes in Zerotier, each pointing to the remote subnet the Zerotier IP of the remote host as the Via address in Zerotier.
3. Add the PBS server to the Proxmox host like normal.

As an example, this is my Managed Routes section of Zerotier with a working backup job.

@gjacobse Try the source, ICANN.

Site seems to use Domains By Proxy, part of GoDaddy,.... maybe,..

ICANN is literally the source of truth so far as internet domains are concerned.

The domains I'm responsible for always reflect the correct information there.

Hopefully the one you're looking at isn't behind a privacy screen, most are these days.

I found that the name has changed to UniGetUI recently. I've been using it recently since it does all the Windows repositories I know about.

@Oksana said in What is the Best Type-2 Hypervisor?:

Wondering what’s the difference between Oracle VirtualBox, VMware Workstation, and QEMU? Check out our latest comprehensive comparison by Dmytro Malynka, StarWind Product Manager, to choose the best Type 2 hypervisor for your virtualization projects. Read more here: https://starwind.com/s/9S

This graphic is very deceptive. The article never mentions using QEMU with VirtualBox, only KVM.

Going over a bunch of Scotts (now old) videos and documentation on SANs to do a brief overview with our sales team. They might be oldish now, but still the best refence material around.

I had another look at updating my Cloudflare domains using dynamic DNS, and found that it is very easy now compared to a few years back.... I think 2018 was the last thread I found on it.

Anyhow, super simple.

Start by creating a new API key with DNS update permission.
Using a current Ubuntu.
apt install ddclient
Follow the instructions.

One of the things I've been doing a lot of lately is adding drives to virtual machines. This can be done hassle free, but almost all instructions found online make you find the correct bus to use. There is no reason to spend the time to track down the proper bus to scan when you can scan them all in one shot.

for host in /sys/class/scsi_host/*; do echo "- - -" | sudo tee $host/scan; done

I can't find the original reference for where I first found this. It was one of those, why didn't I think of that moments.

@dbeato said in Anyone hosting your own S3 bucket?:

@travisdh1 Are you using a Scale Cluster or just a straight made up cluster of your own?

We'll be using a cluster of our own. Doubt it will make sense to use Scale in this scenario as it will be purely storage, no compute.

@dbeato said in Anyone hosting your own S3 bucket?:

@travisdh1 I haven't done so, It would be interesting to review that option.

Part of the issue is that I'm not sure how much total storage we're currently running via HDD. I happened to mention the SuperMicro 60 bay chassis filled with 20TB drive price point that made it to owners ears, and now I get to write a proper proposal up.

Honestly, I'm going to push for a 3node Ceph cluster as a starting point. The cost for the maintenance contract on that is ~$200,000.00/year, and the SuperMicro as described with a 5 year warranty would run ~170,000.00 for us.

Having to commute every day is a little bit of a pain, but the datacenter work is a nice change of pace!

So this question is purely because I'm not sure we're going to immediately scale to where we need a 3node storage cluster at work. If they decide to go that way, we'll just use the native Ceph S3.

Anyone hosting your own S3 bucket, and which of the S3 compatible software are you using?

Next up from the Docker site, how to actually enable the GPU in a Docker Compose file.
