Крастерский маршрутизатор на FreeBSD из старого компа

Доброго свободного времени, товарищи! в этой своей первой статье хотел бы вам рассказать как я будучи далёк от сетевых технологий перешел с роутера мыльницы на старый комп из-под дивана.

Finally (2), I have some good enough DHCP server! :drgn_aww:

Tried kea from ISC — it works but requires some additional actions to be launched under #NetBSD. It has very strange default paths for file with leases, PIDs and logs:
- /usr/pkg/var/lib/kea/
- /usr/pkg/var/lib/run/kea
- /usr/pkg/var/log/kea

BTW, it could be changed via playing with some environment variables.

Also, the default startup script uses keactrl to launch DHCP server and keactrl requires some configuration for it. So, to use "service kea start" there are two configuration files are necessary:
- /usr/pkg/etc/keactrl.conf — the main configuration file for server.
- /usr/pkg/etc/kea/keactrl.conf — the configuration file for keactrl.

Then, I tried the dhcpsd — the new promising successor of ISC dhcpd, which could be configured with configuration file in Lua and conforms Unix FHS — all necessary files lies in the right places: /var/run, /var/log, etc. Sadly, it doesn't work: server starts but there are no leases for clients and no any errors in the log :-(

Then, I found cmu-dhcpd in the repos — there is a dhcpd from Carnegie Mellon University with some patches from Princeton. And, finally it works! And it also conforms Unix FHS: main configuration in the /etc/dhcpd.conf, PID-file in the /var/run/dhcpd.pid and logs in the /var/log/messages :drgn_aww:

DHCP: настройка серверов, Relay и анализ трафика в Wireshark

Приветствую! В любой сети устройства должны получать IP-адреса, шлюзы и DNS-серверы, чтобы корректно обмениваться данными и иметь доступ в Интернет. Конечно, можно настраивать всё вручную, но в реальной жизни это неудобно и часто приводит к ошибкам. На помощь приходит протокол DHCP (Dynamic Host Configuration Protocol) . Его задача проста - автоматически раздавать клиентам все необходимые сетевые параметры, включая IP, маску подсети, шлюз и DNS. В этой работе мы подробно разберём, как работает DHCP, от процесса обмена сообщениями DORA (Discover, Offer, Request, Acknowledge), через анализ сетевого трафика в Wireshark, до настройки DHCP-сервера на MikroTik и Ubuntu-Server . Мы также рассмотрим дополнительные возможности протокола, такие как DHCP Relay, который позволяет обслуживать клиентов в других подсетях.

I spent the initial portion of the morning mucking with #dhcpd so that one of my ethernet devices could assign a fixed ip to the #XR18 simply so i could use the mixer (X Air Edit) on my desktop. Big fun.

La communauté “OpenBSD pour tous” annonce l’impérieuse nécessité de `syspatch` OpenBSD !

1 faille "sécurité" dhcpd

----

It's time to `syspatch` your OpenBSD 6.5 or 6.6, for the server dhcpd, on all supported architectures.
