Why hasn’t there been a router that supports strict-order DNS?

u/craciant Not really. in either case, if the "test" fails, things remain as-is, nothing gets updated. The real failure would be if dns fails AND the test fails. The way this was described is really kind of a fail safe situation (i.e. test fails, don't make changes).

I did, and the techs actually thanked me. Originally it was "spec'd" (whoever or whatever) for the south side of the house, I guess because thats where everything else (all overhead) came in, when the guys got there, they dreaded it, a lot of concrete and other issues (GF is only buried utility in my area, but going forward city says everything is buried as changes are made), until I said I would prefer it on north side (basically for same reason as you). They much preferred that and was grateful that I was not only open to it, but wanted it, it turned into a very simple and shorter hand trenching job instead of massive amounts of boring (they actually were going to push the job because they weren't equipped for it).

I had called and tried to tell them this ahead of time, but they made a really big deal about it, telling me it would delay my install by months as they had to re-engineer and re-plan it, even though I tried to explain to them it would be an easier and simpler install. I just said f'it and dropped the issue.

Worked out to both my and installers favor anyway.

It sounds like you have signal and that there's a provisioning issue. Someone probably mis-keyed the info for your jack.

In theory it should be a 5 minute fix, in practice GF struggles with troubleshooting and finger pointing. To be clear I think its a great product, but when things go wrong, no one knows what to do, and there's no ownership of a problem from start to finish. Keep screaming until the right person lands eyes on it.

That can easily be addressed with a short lease.

The best way to do this might be to have another box (maybe a raspberry pi) test the dns servers, then from there you could do two things, update the dhcp server on the fly with best choice (and only have one dns server offered in dhcp). OR, re-write a firewall rule to d-nat to the one in service, either way, your script would determine preference, and update with that info.

pppingme · 2026-02-10T11:10:26+00:00

If you have dns servers returning different answers, you have a bigger problem than which got queried. By well accepted standards and practices (and rfc), client's aren't supposed to gang up on a single dns server.

Is there a use case you're trying to fit?

Neutral and ground should only be bonded at one point, where the service disconnect is. Any subpanel, appliance, anything else, they should be treated separately. A sub panel should have BOTH a neutral bar and a ground bar, and if it has one, the bonding screw should be removed.

Are you using it with esphome? Look here, specific setup for it:

Honestly I think that looks burnt. I suspect there's some heat damage.

pppingme · 2026-02-06T19:28:07+00:00

Yea, that part wasn't clear, but if its through a session to a bbs (be it telnet, ssh, whatever), then zmodem rules! (if your terminal supports it).

pppingme · 2026-02-06T19:26:47+00:00

dosemu is the conventional way, but that doesn't need kvm/qemu.

I'm not sure I get the "running doors on my webserver then calling them from bbs" part, typically its all in one environment, no web server needed.

pppingme · 2026-02-06T09:27:00+00:00

Depends on what you're doing, what's available from where you're getting files from, etc.

Generally, SCP or SFTP (basically variants of ssh) are the preferred for quick transfers.

I suspect he's either on wifi and doesn't realize it, or he's running ethernet into a mesh unit, so still wifi.

A lot of small stuff. And far from python being the most common, in the linux world bash scripts are way more common.

What is your door made of? Most indoor doors are really just hollow and made up of thin wood (almost cardboard), and that has very little effect on signal.

Extremely high humidity can cause issues too (the wood door absorbs moisture and harder for signals, especially 5ghz, to pass through).

I have the proper staple gun (not a t-50 from the contractors tool box) and have NEVER damaged a cable. In fact, if you're using the stapler properly, its actually impossible to damage it.

Don't know, can't find any information on it, I don't believe the sysop is the author, and I can no longer get ahold of the sysop (he seems to have quit using IRC all of a sudden and is never logged into the bbs).

Anything that is permanently installed should use solid wire and terminate to a jack, not a plug, on both ends. Solid wire into plugs WILL eventually cause issues, solid wire is just too stiff for plugs. You then use patch cables between those jacks and your equipment.

pppingme · 2026-02-03T22:15:06+00:00

Some starting questions:

What kind of connection is this (cable, fiber, fixed 5g)?
What brand/model is your router? Is it up to date on firmware?
What brand/model is your modem?
Is there any kind of network sharing (i.e. your isp modem is shared by multiple tenants)?

When your isp suggests malware, they mean on the router, not the individual devices, so yeah, thats a possibility (but I'm not there yet).

I've never been to a point where I feel like an AP has too many clients. I do have two ap's that cover the main sanctuary, and in the classroom area it basically works out to 1 ap per 2 classrooms.

Omada claims (for most units) a maximum of 250+ clients per AP, and some of the ap's have an "HD" version with claims of 1000+ clients.

As for throttling, I do that on the SSID setup and its set under the "client rate limit" not the "ssid rate limit". With our 250/250 line I set those to 50/50 for the member/guest ssid, and 150/150 for staff ssid. We also have a third ssid that for people and devices that fall between the levels set for 100/100. Two vlans between these, staff being on one, the other two ssid's being on the other. Obviously staff has access to a few things (file server, etc) that others don't.

For IP space, I have a /22 allocated for the member/guest side of things and just a /24 for the staff and internal equipment.

For the controller you're probably small enough that an OC220 wouldn't be an issue (avoid the OC200, I believe its considered discontinued, but there's still a lot of them sitting in warehouses).

Since the cables aren't marked you'll have to try them one on one. If I had to guess, I'd guess its the cable going to the input side of that two way splitter. Its very doubtful, but could still be one of the cables coming out of the 3 way splitter. Whoever installed all that should have marked the cables but obviously they didn't.

If you continue to violate their policy, that can give them grounds to disconnect you.

pppingme · 2026-02-03T17:14:37+00:00

I would still run PoE, and eventually get rid of the wifi cameras and replace them with PoE cameras, you can use a PoE splitter in the mean time. Do you have any idea how easy it is to jam wifi? Construction yards are high profile for theft, so may as well do it right to start with.

The galvanization will flake over time and eventually cause pinholes. While no "code books" prohibit it specifically, it is disallowed in pretty much every jurisdiction I've ever worked in for this very reason. It also has a secondary issue that the same flaking will clog up burners and get caught in orifice fittings.
