new core networking docs and openrc

[Daniel Robbins]

Hi All,

I have some beta core networking docs available here:

http://www.funtoo.org/en/funtoo/core/networking/

Also, a new openrc is in the tree which contains a few more updates to the network interface configuration templates.

I'm getting pretty close to releasing this. :)

Thanks for new docs.

[Dominik Riva]

Looks good.

In the Wireless Configuration I think it should read
# rc-update add wpa_supplicant default
in stead of
# rc-update add dhcpcd default

One thing that is not clear to me is "Using the Template System".

Is it optional? If so why should I use it?

What is it's purpose?

How does it work?

I am sure that all this would be clear if I take a look at the scripts
but from the glance of the docs that I just had, I can't answer my
questions.

Regards, Dominik

Hi, there!
Thanks for new docs and new upcoming openrc. I found minor problems
with network core. I have funtoo box running cpu-intensive
calculations that transferring them by ssh into 2nd box where I can
interpret them, etc, so my 2 boxes are configured static IP's
(netif.eth0 works fine). The problem is, you can't use ppp-connection
(I live distant from wired connections, so ppp only possible way to
get into world wide, portage sync and emerge)if netif.eth0 running-
pppd is not starting, and if pppd already started and you trying to
bring up netif.eth0, ppp-connection will break.I have nameserver
strings in resolvconf.conf (from my ISP) used by openresolv, probably
there is a confilct, not sure.It is not that big problem as I can run
my tasks on static IP, then use ppp for system updates or else but if
someone need to run both connection, there might be a problem.Once
again thanks for new network core, it is really faster and more
flexible than Gentoo one.

Hi Daniel,

Another thing that may be pointed out in the DHCP-based IP Auto-
Configuration section, is the possibility to configure static IP in /
etc/dhcpcd.conf. I have been using this method until the present
without any issues. :)

Cheers,

MH

Thanks for that fix.

I think this is covered in the docs. I may add a "benefits" section to the top, but the benefits are described in the "Differences from Gentoo" section if you read it.
There is also a section that explains how to use it.

I am not sure why this is happening for you but it sounds like it's due to your pppd script -- it should be possible to get it to work the way you want.

I am not sure why netif.eth0 would kill your pppd connection - maybe it is because you are specifying a gateway, which is overwriting the default gateway setting from pppd? Try turning off any GW setting.

-Daniel

[Daniel Robbins]

Yep, I'm aware that this is a possibility, but I forgot exactly how to do it :) Can you post your setup here?

-Daniel

[Oleg]

Hello, Daniel!
I removed a GW from /etc/conf.d/netif.eth0 (new openrc-0.5.2-r1) and now everything is working, there is no conflicts between interfaces.Actually
I don't need both running but just tested and no errors.Thx

[mikehunt]

Yes of course, in fact I took it straight from the man page:

# egrep -v '^(#|$)' /etc/dhcpcd.conf
hostname
option domain_name_servers, domain_name, domain_search, host_name
option ntp_servers
option interface_mtu
require dhcp_server_identifier
nohook lookup-hostname
interface eth0
static ip_address=192.168.2.10
static routers=192.168.2.1
static domain_name_servers=192.168.2.1

That reminds me there is no official ppp connection method, is there? I've just
made my own script which works without issues, but there is a more funtooish
:P approach?

For example, turns out that from time to time my ISP likes to kick me off the
internet, and I know I could face this issue through some script (I must
confess, I hadn't time to work on this, or i haven't been in the mood to do
it), but it would be nice to have an official script with connection control,
etc.

Paul.

HI All,

Just installed openrc-0.5.2-r1 with no issue. Added a "SLAVES="netif.eth1""
to the /etc/conf.d/netif.br0 file for my bridge interface. I'm guessing that
I can add additional interfaces (tap, etc) with a space between them?

The script works great! Thanks! Is there any method for DHCP yet?

Thanks,
Ryan

Great, glad for the feedback. Yep, if you add more SLAVES, do it like this:

SLAVES="netif.eth1 netif.tap0 netif.wlan0"

Just make sure all are prefixed with "netif".

For DHCP, I am relying on dhcpcd 5. Specifically what functionality are you looking for?

[Ryan Holt]

Nothing particularly special... Just a client system receiving DHCP
addresses.

Thanks,
Ryan

Heh, I'm sorry, mental brain-fart... Just edited /etc/dhcpcd.conf and added
the line 'allowinterfaces eth0'. DHCP functionality is fine.

Added a new template for alias interfaces. This depends on the parent
interface providing the gateway and nameserver settings.

Template:

fs init.d # cat /etc/netif.d/alias
#!/sbin/runscript

depend() {
config "$CONFD"
need $PARENT
}

die() {
eend 1 "$*"; exit 1
}

start() {
ebegin "$STARTD"
require IP NM
ifconfig $INT $IP netmask $NM up || die "Couldn't bring $INT up"
eend $?
}

stop() {
ebegin "$STOPD"
ifconfig $INT down || die "Couldn't bring $INT down"
eend $?
}

And here's a sample configuration file:

fs init.d # cat /etc/conf.d/netif.br0\:0
template="alias"
description="Alias Interface"
PARENT="netif.br0"

IP=10.9.18.253
NM=255.255.255.0

And the startup script is /etc/init.d/netif.br0\:0 in this case.

Thanks,
Ryan

Very nice. Thanks for sending this in and I'll get this added to the
next revision of the package.
