The new OpenRC networking script

Message

Etal · Post by **Etal** » Sat Oct 10, 2009 9:15 pm

The new OpenRC (0.5.1) got this new flag:

oldnet: Install the old type of network init-scripts with a symlink net.IFACE for each interface

So apparently now, instead of the usual net.eth0, net.wlan0, etc., there is a new way to do things; however, I can not find anything about it except the 0.5 announcement and announcement of the networking change...

Is there any any actual documentation on how to migrate to and use the new network script (aside for the comments in the file)?

Wondering myself...
Anyway the good old, wpa_supplicant -Dwext -B -c /etc/wpa_supplicant/wpa_supplicant.conf -i wlan0 + dhcpcd wlan0 works as always but it really seems this openrc update was a bit rushed without any proper info to get it working.
Why would you want to stick with anything that has "old" in it's name after an update? :D

Over at Funtoo there is some documentation on it. Not sure if it applies to Gentoo but i would think it's the same.

Follow this thread: (openRC support thread - there is some information there)

In fact, it's time to have an official migration guide or something that we can read more about it officially.

The Funtoo doc is good, but we need a Gentoo guide too here

Yeah, an official guide is really needed.

The Funtoo guide, though, is actually different from openrc - they're trying to get rid of the networking configuration "infrastructure" entirely, and just use the tools like ifconfig directly. Which actually sounds really nice, except there does not seem to be a comprehensive guide so that I could learn how to do what I want without ending up with no internet.

Here's what I currently have and what I want to keep: netplug manages which interface is used based on whether the ethernet is plugged in, wpa_supplicant manages the wireless, and the IP addresses are acquired via dhcpcd. How to start it all up manually, I have no clue.

In fact, I have no clue too.

Maybe if you use the use flag that disable the new stuff from OpenRc, then maybe you will be able to run like you are used to do.

If you find something, just post here

I am running with oldnet, so it is working fine. The reason I'm posting here is because I want to learn a new way

I guess I'll have to wait until I have a few days of free time and read some docs on how all the components fit together. Can't do it now because losing the Internet connection would be a big no-no for me.

In fact, testing some network stuff can be pretty hard if you actually crash your internet connection.

Until the release of an official guide, I will mask the 0.5 version or at least I will use new the use flag that remove all the new stuff.

What if we already installed 0.5.1?

I installed it yesterday, THEN read about all this stuff. I am afraid to reboot my system fearing my network/internet will no longer work.

Do you have a general idea about when an official guide will be released? I would like to learn the new way of doing things too.

Update: I see openrc has the "oldnet" useflag set, does this mean my net.ethx will work and I can reboot without any problems?

As far as I know, yes.

I mean the new use flag oldnet

Code: Select all

# quse -D oldnet
local:oldnet:sys-apps/openrc: Install the old type of network init-scripts with a symlink net.IFACE for each interface

I have openrc 0.5.1 installed now for a few days, and oldnet useflag was set by default profile. Reboot has not been a problem.

Come on, drop ifconfig support for good in the new openrc!
What is this mess with bsd kernel tools and linux kernel tools?? Have specific scripts for each kernel, bloody hell!

iproute2 only exists in Linux, so no.

Again no, scripts should be portable across kernels and tools where possible.
I see no benefit in ignoring ifconfig for this

I forgot to add for the Linux kernel.

I do not agree, I think that anything which is too intimate with a kernel should have specific code and scripts (and I see BSD code as a threat so it does not help). Moreover bsd ifconfig is different from linux ifconfig (which has been meant to be replaced by iproute2 for years), that's why you have many switches in the script to handle the 2 ifconfig differently.

Well Roy Marple choices are different and I don't have time to allocate in order to maintain a lean and clean GPL linux version of openrc, then I shut up and sharpen my anger silentely.

What's up with initng and upstart for gentoo?

Across kernels I agree, if Gentoo want's pure linux init scripts it can provide them itself. But across tools is exactly the old net.lo approach. So I was wondering myself why the current script "network" doesn't come as three different scripts. As net.loopback, net.ifconfig, net.iproute2 for example. This would also allow neater configuration files I guess.

I tried the new setup. It works quietly, and quite well. My only question/suggestion is perhaps the next version might be intuitive enough to not change things back once you get the new script setup. This change might inspire me to put baselayout-2/openrc on another of my machines.

Blessed be!

Sheepish head slap! I suppose using -oldnet is a good way to get that done. Who needs intuitive? hehehe

Good work on this one. I have it set up properly now. Love it!

Blessed be!

So right now, do you have a working lan card and what about your Wifi card ?

Can you tell us more about your experiment ?

For the wlan card.

Build the wpa_supplicant init script as described in post: [post=6008568]6008568[/post].
Add it to the boot or default runlevel.
Put something like:

Code: Select all

wpa_supplicant_conf="/etc/wpa_supplicant/wpa_supplicant.conf"
wpa_supplicant_if="wlan0"

into /etc/conf.d/wpa_supplicant.
Done.

If it does not exactly what you want edit the init script.

I use a wired connection to the internet (net.eth0).
Reading this thread I got scared because I updated openrc to 5.1-r1.
I checked /etc/conf.s/net and it had oct 15th datestamp.
The emerge had copied the contents of my previous file into it!
The same happened to /etc/conf.d/network.
I've rebooted and no problems.
