DYN / OCI DNS migration?

Has anyone tried to Migrate any of their existing DYN DNS zones to the new OCI platform they are trying to roll dyn customers to?

​

I haven't had much luck getting their UI to work except for the first couple times I migrated some test zones over to OCI. Since then, the UI tool is broken and nobody from Oracle can tell me why it's broken (big surprise huh?) I've since been told to use a convoluted python script in their custom CLI to do the migration which seems like a hell of a lot more work than using the 3 clicks their UI tool would've done.

​

​

Anyone else having issues with the tool right now or can try to use the zone migration tool and see if you have the same issue on your accounts?

Question about this Packet Tracer Activity

It says at the top to configure each switch with a default gateway address. For each server, staff and student network, I configured their default gateway as .1 in the 4th octet. For example, server room default gateway is 10.10.10.1

It then says in the below table that the interface G0/0 for the server network must be the "1st Address from each allocated range", which in this case for the server is 10.10.10.0/24 network.

Would the 1st address be 10.10.10.2 because I had used 10.10.10.1 for the default gateway of the server room switch?

Issue with NPS not authenticating some Windows clients

Hello,

We've been using NPS (2x NPS servers with Aruba IAPs) with machine authentication for a while now without any issue. We've just received a new batch of devices (laptops, tablets) and after deployment, we realized they do not want to connect to our secure network. Everything on the clients seems fine, they have a computer certificate, are domain-joined and get the policies from GPO. At first, I thought it was an issue with those new devices, but after wiping my own (old batch) PC to test, it doesn't work either. So I thought it might've been something with our OS deployment, but today I wiped another old computer and this one works with our secure wireless network. This working computer has the exact same drivers as my personal computer (which doesn't work). It seems to me "Machine authentication" is not working with those devices as I get a prompt for username/password. I am at a complete loss as to what causes this and need to fix it before the lockdown is lifted or else things are not looking good.

On the NPS server logs, nothing seems out of place. When a computer authenticates, it shows the computer account object as a "user". When I try to use a computer that doesn't work, it just prompts me for user/password and that fails as we use machine auth. I don't know why it's not forcing trying machine auth. The NPS server certificate is valid. Certificate stores for a working vs non-working machines are identical.

Slow upload speed

Hello, guys. So basically my problem is that my upload speed on my pc is extremely slow (i am talking 0.4 mbps slow) but on my phone is actually good (20 mbps). Can you help me speed things up? Thank you in advance

Cisco 2504 has been EOL/EOS since 2018, but are the AP adder licenses also EOL/EOS ?

Can I still officially buy AP adder licenses for the 2504?

Thanks

Network monitoring/inventory system for a small school

Hi everyone. I'm currently doing an internship in a small middle school in Belgium. The school has about 500 students. The network admin has given me the task to look for software that scans/checks the network for all connected devices. The software has to list all the hardware on the network and needs to be able to check what os and what update said device is running on. The ability to check what apps/programs are installed would be a plus.

The main goal is to have a nice overview of all the connected hardware. Advanced network managing capabilities will not be needed.

Since we are only a small school we are wondering if there is good free software that exists for this purpose. Paid software is possible if the cost isn't too high (more than €1000 per year would be a lot)

Thanks in advance.

Is subnetting secure?

If I divide a network into subnets, and take care in routing appropriately, is this considered secure/isolating? or do I need to consider other things too?

Anyone know how this site created the diagrams on their frontpage?

Using old, not supported switch tranceivers

Hello,

We are upgrading our HP core switch and even though the transcievers we currently have are not supported anymore our vendor said they will still work and is ok to use on the new switch.

Later on I think we will replace but is there any downside to using previous old not support versions of tranceivers? It's unliekly to have an impact on performance I would guess.
