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.
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.
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…
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.
The only way to connect the SIM number directly is to hack the VoWiFi protocol, but this is not trivial and you still need to install the SIM in the server.
Option 2 - Buy a home SIP2GSM gateway. But it’s quite expensive (by the standards of my region anyway). SMS work with SMPP, calls work too. For goIP I wrote telegram SMS gateway if you interesting: https://github.com/lifespirit/telegram-smpp-bot
Or use SIP providers from your region/operators that support SIP connectivity and then enable full calls redirection. For calls ok.
UPD: or just use VoWiFi from mobile phone. But you need sim slot in phone.
Anyway in all another way you need install asterisk/freeswitch and write config fot it. And linphone client.
In the initial stage of shared library support, everything was exactly the same. Let’s look at it in 5 years… When some soft will archived and die, some stop maintaining, some new crated and brakes old dependencies…
runtime have versions too. If one runtime version use only one flatpack than exactly same as just static linking binary. Flatpack have just docker layeredfs and firejail in base.
id: org.gnome.Dictionary runtime: org.gnome.Platform runtime-version: '45' <- here sdk: org.gnome.Sdk command: gnome-dictionary
They don’t have to! Flat pack doesn’t remove all other ways to install software. But for 95% of use cases, it will do just fine.
Tell this to canonical, they even firefox put in the snap. You know that when choosing “quickly compile something for a flatpack” and “support 10+ distributions”, the developers will choose a flatpack. Which in general looks fine, until you realize that everything is just scored on the mainline of libraries and molded on anything. The most striking example of this is Linphone. just try to compile it…
Provided that flatpack has a common parent container, which is not always the case. More precisely, it almost never does. Because someone updates flatpack to new versions of the parent containers, and someone else does not.
this is a system for work tasks. Of course, I understand what the developers are going for. that is Android. And it’s really nice to read the Internet on android. But try to do something more complicated than that and you’ll realize that it’s hell. However, I don’t mind if such distributions appear. Why not? I just don’t understand people who voluntarily limit their abilities. And why you don’t just install Android 64?
The flatpack approach automatically remove everything low-level from the equation. Do you want to write directly to the graphics card buffer? Read the input? Do I set the fan rotation parameters directly in the /proc? All these applications will never work in flat pack.
On the other hand, flatpack is superfluous and for convenience. You can simply build an executable file without dependencies and configure firejail for it yourself… That’s all. Or run the file from another user. That is so popular exactly bacause RedHat pushed them. Literaly like Canonical pushed snap.
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/
