how to start dhcpd with openrc and wpa_supplicant?
nona - about 1 month ago -
Hello. When trying to start dhcpd with OpenRC, I get:
# rc-service dhcpd start
* /run/dhcp: creating directory * /run/dhcp: correcting owner * Starting dhcpd ... * start-stop-daemon: failed to start `/usr/bin/dhcpd' [ !! ] * ERROR: dhcpd failed to start
I am currently running
nonsystemd/wpa_supplicant-openrc 20210505-1 (openrc-system),openrc 0.49,nonsystemd/dhcp-openrc 20210505-2 (openrc-world)
and am accessing internet on the same system with dhcpcd. I can see that some configuration may be needed for /etc/dhcpd.conf, but I was expecting the connection to work without tweaking (as it does with dhcpcd). My networking skills are not up to par with the documentation (I would not know how to set it up). Would there be a way to convert the dhcpcd.conf to a dhcpd.conf? Thanks.

Hello . Unfortunately, the forum is almost inactive, I waited a week for an answer to my question)) I see you have no answers, try writing on the forum https://forum.artixlinux.org/ maybe they will help you.
IRC chat is also poorly supported; you can wait a very long time for an answer to your question. I don’t understand why such poor support on all channels is a mystery to me...

Thank you very much, sam. At least, now I know that it's not only me. Fortunately, the packages are still being updated, and that already represents a lot of work.

I had a similar problem, this is the topic in front of you above, I also used Op, look at how I solved this issue, maybe it will help you.

Hello, sorry for the wait. It's hard to say what caused the problem. For start, run process logging system to get information:
$ doas pacman -S syslog-ng $ doas rc-service syslog-ng start
Try after that to run dhcpd and look info in /var/log/*
Also you need to check the configuration. The purpose for which you need DHCPd, I have had experience with dnsmasq for give out addresses, maybe this program can help you and provides more better documentation.
You mentioned wpa_supplicant program. I can't understand what you need: connect to internet via wifi or to setup your own Access Point? If the first one, then it's easier to use NetworkManager (GUI or terminal $ nmcli / $ nmtui with multifunctional configuration files). If the second one, you may want to use hostapd + dnsmasq/radvd I guess.

... need to check the configuration. <b>The purpose for which you need DHCPd</b>
So, dhcpd conflicts with my custom dhcpcd service, and I should configure dhcpd. I hope that it's not so blunt to ask if there is a standard configuration file somewhere, but then again, I can just use dhcpcd and be blissfully ignorant about what it actually does. (I'm calling my self an ignorant in an apologetic way).
I have had experience with dnsmasq for give out addresses, maybe this program can help you and provides ... better documentation.
That is the way: learn as you go.
... wpa_supplicant ... what (do) you need (?) connect to internet via wifi or to setup your own Access Point? If the first one, then it's easier to use NetworkManager (GUI or terminal $ nmcli / $ nmtui with multifunctional configuration files).
There are creepy things about NetworkManager https://labs.parabola.nu/issues/3429 https://labs.parabola.nu/issues/2039 https://labs.parabola.nu/boards/5/topics/1244#NetworkManager (there was a report about a similar situation by someone else here in the forum as well).
wpa_supplicant + dhcpcd was the only way in which I was able to get a radius + wired / wireless (https://labs.parabola.nu/boards/5/topics/1244 https://labs.parabola.nu/boards/16/topics/1495)
If the second one, you may want to use hostapd + dnsmasq/radvd I guess.
I really hope that one day I feel comfortable doing this (I have never done it). I just need some time to learn.

I know so freakin little :( . I definitely need to look back at the OSI model as well. Thank you very much for the links.

Thanks. In the first set of instructions that you post, there are a lot of non-free software. (I would thus recommend beginners to stay away from it). I also do not see anything related to OpenRC. I do value the amount of work that you put into it.
