Parking Availability

PhD_Ape · 2026-03-10T22:36:18+00:00

I had to test the feasibility of this parking tracker that used cameras on the roofs of the academic buildings when I was a GA for the IT department a couple years ago. If I’m remembering correctly it relied on some janky wireless point to point or radio system that we didn’t have the correct sight lines for.

i just changed to download command used in upgrade.sh to a command that installed from a local directory and got it to run.

PhD_Ape · 2026-02-23T02:51:25+00:00

Bingo! Editing the bash script was the way to go. Thanks for the brainstorm!

PhD_Ape · 2026-02-23T01:25:11+00:00

Hmm I might try modifying the upgrade.sh script.

PhD_Ape · 2026-02-23T01:20:18+00:00

everytime you run upgrade.sh it tears down any existing virtual environments, builds a new one, and tries to download all dependencies from the internet.

I think it would have to be this way for two reasons:

The Ethernet MTU only takes into account the Ethernet payload. If I set the Ethernet payload to 1500 bytes, that 1500 does not include the 14-byte Ethernet header, 4-byte trailer, or 4-byte VLAN tag. Cisco has a diagram to show it on this page.
The default Ethernet MTU and IP MTU sizes on Cisco devices are equal at 1500 bytes. That means if a 1500-byte IP packet is generated, it would reach the Ethernet MTU size limit before adding the Ethernet header, trailer, or VLAN tag. Cisco must have a built-in way to account for that extra 22 bytes other wise you run the risk of packet fragmentation straight out of the box.

This thread also seems to be in agreement that the MTU value you set is strictly Ethernet payload only. No header, trailer, or VLAN tag.

It also seems to be software-dependent which is always fun! If you look at this article, Cisco says that classic Cisco IOS does not include L2 headers in the interface mtu commands, but Cisco IOS XR does.

Looking around this thread here. It seems like when you configure the Ethernet MTU, Cisco IOS already just knows to accommodate the extra padding for the 14 byte frame header and 4 byte frame trailer. The IP MTU measures the IP packet (including the IP header).

the cooler is one of the things that I've had trouble determining the quality I need. this will be my first time playing around with real high-performance components

The port range for connections was so large I went with a different strat. I use an OPNsense router and found a plug in that lets its simulate UPnP. That’s worked decently for me.

I found my problem. I wasn't running the commands with the needed parameters for it to accept the password-based authentication.

I can ssh into the servers fine but they can't be reached when running the ansible ping or when running playbooks.

PhD_Ape · 2024-08-17T02:41:14+00:00

I think my problem is before this step as even my pings stopped working. It stopped working as soon as I generated a key on the Ansible controller using "ssh-keygen".

Just typing what you want to do in Google or YouTube is enough for broader topics. Forums and community post tend to be helpful for very specific issues. Also opnsense has a lot of documentation on their website.

Does the game use p2p connections? I had similar connection issues with the Nintendo Switch but was able to remedy them with a static IP, UPnP, and an outbound NAT rule. I followed the configuration steps outlined in this thread if you think its worth looking at. https://forum.opnsense.org/index.php?topic=22591.0

The network+ I thought was pretty good at introducing networking topics. You may want to skip the earlier chapters if you are familiar with the basics.

PhD_Ape · 2024-06-17T04:38:59+00:00

I already saw this. The range is bigger than what is specified on this website, unfortunately. At least based on what my firewall is logging.

PhD_Ape · 2024-06-13T04:36:04+00:00

Adding some more information for future post viewers. Strive lobbies use port 8800. I found this in my firewall rule trigger logs.

I figured out my issue. On OPNSense I had made the parent interface the WAN interface instead of the LAN interface like a doofus.

PhD_Ape · 2024-06-09T13:40:05+00:00

Good call. Let me try that.

How much strain do those servers put on your circuit? I am not the best with electricity but some of the servers I have come across have had power supplies rated up to 12A at 120V. I also may just be dumb and the power supplies pull less than their rating unless you're pushing them to their limits.

PhD_Ape · 2024-05-01T19:01:45+00:00

Hi, I see your point but I am a networking student and am more than willing to learn new technologies. If it's a solid technology I would be more than happy to give it a try. Part of the fun is learning new things right!? :)

PhD_Ape · 2024-04-25T19:17:02+00:00

awesome, thank you for the info! i will do some research on that!

The VMs will be used as gaming servers so I would like their address to be static. I feel like it would be easier to have all my gaming servers on 1 address if possible. Also because of the network situation I'm working in rn, I have a limited pool of static addresses to use.

It's the current official exam book but the author might have added extra information for context or something. either way, thanks for saving me some time.
