ISC really deprecated… =( You can install dnsmasq of course, but he is much more slow. But nice for small networks.
Firewalld is much worse for small sustems. Who is really need mark ports? But in difficult cases you need write iptables rich rules anyway. So, as result I love old school with clean iptables without any upperlevel daemons.
Enable packet forwarding via interfaces:
# cat /etc/sysctl.d/01-forward.conf
net.ipv4.ip_forward = 1
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.default.forwarding = 1
Then install isc-dhcp-server and configure ipv4 and ipv6 dhcp server. (only on local ports or you internet prowider will be angry)
short example:
# cat /etc/dhcpd.conf
ddns-update-style interim;
ddns-updates on;
ddns-domainname "my.local";
ddns-rev-domainname "in-addr.arpa";
allow client-updates;
update-conflict-detection true;
update-optimization true;
authoritative;
default-lease-time 86400;
preferred-lifetime 80000;
max-lease-time 86400;
allow leasequery;
option domain-name "my.local";
option domain-name-servers 192.168.1.1;
lease-file-name "/var/lib/dhcp/dhcpd.leases";
# cat /etc/dhcpd6.conf
ddns-update-style interim;
ddns-updates on;
ddns-domainname "my.local";
ddns-rev-domainname "ip6.arpa";
allow client-updates;
update-conflict-detection true;
update-optimization true;
authoritative;
default-lease-time 86400;
preferred-lifetime 80000;
max-lease-time 86400;
allow leasequery;
option domain-name "my.local";
option dhcp6.name-servers fd00:1::1;
option dhcp6.domain-search "my.local";
option dhcp6.preference 255;
dhcpv6-lease-file-name "/var/lib/dhcp/dhcpd6.leases";
don’t forget start dhcpd@lan and dhcpd6@lan
Then install radvd and configure RA ipv6 broadcasting. (only on local ports or you internet prowider will be angry)
# cat /etc/radvd.conf
interface br0
{
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvDefaultPreference low;
AdvHomeAgentFlag off;
prefix fd00:1::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
RDNSS fd00:1::1
{
AdvRDNSSLifetime 30;
};
DNSSL my.local
{
AdvDNSSLLifetime 30;
};
};
Then install iptables-persistent and configure ipv4 and ipv6 rules in /etc/iptables/ . Change lan and internet to you real interfaces.

Then install dns relay. I user bind, but that some overkill. But anyway:
install named / bind9
# cat /etc/named.conf
...

All done.
Well… In my case, as many potatoes as you want. Even if I grow it on an industrial scale, I will only need to pay 4% sales tax. And for myself, I can grow at least 100+ kg of potatoes without any problems. (Because of the size of the plots, I can literally grow tons of potatoes).
And yes, I use UV lamps for seedlings every spring. Just like literally everything in my village. This happens when the daylight is very short. These are the countries with risky agriculture. I think it would be funny for some foreigners to watch the picture of the village where in every house at night with ultraviolet light shining on the windowsills =)
archlinux + podman / libvirtd + nomad (libvirt and docker plugins) + ansible / terraform + vault / consul sometimes
UPD:
archlinux - base os. You never need change major version and that is great. I update core systems every weekend.
podman / libvirtd - 2 types of core abstractions. podman - docker containers management, libvirtd - VM management.
nomad - Hashicorp orcestrator. You can run exec, java application, container or virtual machine on one way with that. Can integrate with podman and libvirtd.
ansible - VM configuration playbooks + core system updates
terraform - engine for deploy nomad jobs (docker containers. VMs. execs or something else)
Vault - K/V storage. I save here secrets for containers and VMs
consul - service networking solution if you need realy hard network layer
As a result, I’m not really sure if it’s a simple level or a complex one, but it’s very flexible and convenient for me.
UPD2: As a result, I described the applications level, but in fact it is 1 very thick server on AMD Epic with archlinux. XD By the way, the lemmy node from which I write is just on it. =) And yes, it’s still selfhosted.
after testing a bunch of different apps, I settled on a notebook and a pen. There’s nothing more convenient than writing down your tasks and plans in two columns and then simply recording the results the next day.
Short answer: Yes. and you can install extra/podman-docker 5.5.2-1 ( Emulate Docker CLI using podman ) for full compatible.
Long answer: you can find all in official docs. https://docs.podman.io/en/latest/ . in general, the first step is always better not to ask abstract question in Google, but to read the official documentation
There is no such distribution. And it’s not surprising. That is essentially one package with runc. I also recommend using an podman instead of docker. Then you won’t even need to do anything except apt install podman / dnf install podman.
UPD: At the moment, even systemd supports containers. systemd-nspawn daemon…
Well, I’ve lived half my life without the Internet, because it wasn’t invented yet, and if things really go this way, I’ll live the rest of my life without the Internet. No digital sharing, no digital spying. And I recommend that you disconnect from the network for a couple of months and touch the grass too.
As the say: You’re ripping off your heels, you’re not respecting the men
I’ll do the “Ku” pose from the movie Kindzaza a couple of times and the dog will come running to jump around me. For some reason, he loves it when I do that.
I often clean and place aromatic oils in the rooms + live plants.
For most of human history, salt has corresponded to this definition. Have you ever wondered why it’s called a salary?
It’s very nice when your wallet is barely keeping afloat and you’re left without money because salt gone form wallet… Or do you mean super cheap rock salt?
Well, to be left without money because I got caught in the rain is not still a pleasure.
Tungsten is also one of the rarest minerals on Earth, despite its relative cheapness.
Good… At a time when gold was still a currency, tungsten was not yet able to be smelted. In addition, when heated, tungsten is reactively oxidized, unlike gold.
Well, what kind of items are these that are rare, they cannot be made as much as you want, they do not deteriorate over time And allow processing?
The value of gold, silver and platinum is determined by two factors: there is little of it in nature and you cannot take more at will and it does not oxidize, which ensures good storage.
I really don’t know about you, but in my country you can’t take gold out of the bank. You buy gold from a bank and it stays in the bank longer without the possibility of taking it out. What a joke. Guess what happens to the bank and the gold in it when the economy collapses.
And now look at Bitcoin. there is a little of it, you can’t increase it at will, and it’s convenient to store. Does it remind you of anything? And it’s always with you.
or they can simply inherit the UNIXTIME library, in which 0 has shifted from 1970 to 2038, and add one additional “time epoch” flag. Think about what’s easier - create your own time library or inherit from unixtime?
Bitcoin is a pyramid scheme because it only keeps its value as long as people are constantly buying it. If no one wants to buy it, the value of any amount of bitcoin is zero. This is why people who have bitcoin are trying to convince anyone else to keep buying.
any currency is initially a bank’s promissory notes, and then a promise to exchange the paper for some kind of labor. As a person who has experienced at least one default in his life and whose entire toilet is covered with USSR money, I can say that in this regard, no currency is different from bitcoin.
1 BTC for a pizza, or whatever
10 000 BTC for 1 pizza…
hyperinflation
Deflation . This is literally what happens to any volute that cannot be printed indefinitely. The situation is complicated by the fact that many wallets are simply lost and bitcoins will never be recovered from them.
After all, if people are willing to read what they’re given, why not? If they like to read books with the quality of neural networks, then there’s nothing you can do about it. All that remains is to be better than the neural network. In any aspect. And you will find your reader.
But yes, the human creativity of widespread consumption is slowly dying.
ISC DHCP switched to KEA DHCP, They don’t have package in Debian repo, but you can add repo and install: https://cloudsmith.io/~isc/repos/kea-3-0/packages/
