I’ve been dealing with lawyers and court recently, they may be above average in terms of intelligence and drive but most wouldn’t be extremely above that average. I’ve had to explain fairly basic math, with easy numbers (fractions like 1/2 and 1/3 regarding pay structure), several times already. Ie
Still had to explain that bonus is 1/3 total not 1/2 total.
Taxes on $300k in a year would make it impossible. Would probably have to make $400k in a year to have a chance with expenses and living frugally or 2-3 years @ $300k/year.
Short answer no, but you can add the source IP as part of the http header https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/ then you have to log that bit of the header at the app level.
There can be ways of your are using ipv6, basically turning your cloud host into a router, but but ipv4 you would have to have a 1:1 mapping and setup the routing carefully to make it work.
You can add net_admin to the user running podman, I have added it to the ambient capability mask before, which acts like an inherited override for everything the user runs.
Wildcard DNS entries are not part of an RFC afaik, so the behavior is completely determined by the dns software in use. AD and I think bind state to only use them in an otherwise empty zones, though one case I have at work we have to have the wild and an A record in the zone. Hit strange intermittent failures to resolve without the record in for some reason.
Rereading what you have in the zone file, if that is a standard bind zone file, a subzone definition would look like
` ; sub-domain definitions $ORIGIN local.example.com.
What you have might work, but doesn’t follow the dns RFCs the dns label is “*.local” in the “example.com” zone/domain.
This may come up after you get the API to the public DNS provider working, as the software will add/update a “_acme-challenge” label in the zone you point it to which would be “example.com”
If the dns provider makes setting up a proper subzones hard, you can work around it by adding a cname record
_acme-challenge.local in CNAME _acme-challenge.example.com
I assume you have purchased as public domain (the example.com bit) and have it setup to be publicly resolvable, even if the records are hosted on cloudflare or something.
You don’t need any A records for the dns01 challenge from lets encrypt. You need a text record for _acme-challenge.local.example.com that you can update with what ever challenge string let’s encrypt replies with when you request the *.local.example.com certificate.
Guessing the error is from caddy and it is saying it can’t find the public provider of that zone to update the txt record for the challenge. Even if you have the correct provider configured, does local.example.com exist in the public DNS server config?
As a side note, after the cert is issued the _acme-challenge txt record can be deleted, just be aware all issued public certs are easily searchable by domain name.
That would still technically be a math problem. I’m not sure if it falls in combinatorics, statistics/probability, or scheduling, but I’ve had problems like this on math and cs exams.
