2 questions:
- what is the default value for allowinterfaces?
- why doesn't configuring an interface via 'interface foo' add it to the allowed interfaces? |

The default value for allowinterfaces is nothing, which is to say allow all interfaces except for loopback and pointopoint interfaces.
As to the latter, well that's a good question.
I suppose that if allowinterfaces is NOT defined in the config, we could append it in code.

So is 'allowinterfaces lo *' actually equivalent to just adding lo or does it also add pointtopoint interfaces?

Does that even make sense at all? I mean creating a specific configuration for an interface while not letting dhcpcd discover it?
Because otherwise I'd say add it to allowinterfaces unless it's in denyinterfaces. |

Heh, yeah it does by virtue of the *

Yes in my mind it does make sense.
Take apache, or any server daemon, with allow/deny directives. They override any other setting. dhcpcd takes the same approach.

Sooo … 'allowinterfaces lo *' actually does the same as 'allowinterfaces *'? |

Hmm I agree it should just add a configured interface; it seems odd to have allow everything, and really I'd just want whatever I configure as root to be added to the set, without needing to do anything else.
Apologies if I'm missing some subtlety. |

I forgot about that post but anyway the first post in this topic, which is *the* reference, has already been updated.

Well, not sure if this was the intent but let's not confuse *configuring* an interface and *bring it up/down*, which aren't the same thing. To me at least. As a matter of fact, leaving allowinterfaces blank doesn't stop dhcpcd from configuring the interface. The directive must include lo to also bring it up.

VinzC ......pssssst
have a look at RedHat and CentOS scripts "ifnetup and ifnetdown"
they usually work fine and might help you and us all  |

I prefer dhcpcd's simplicity though. One script, one config, fits most cases. I know CentOS/RH network management but I still find it too complex for the simplest setup.

However, allowinterfaces is still respected above everything else. |
Ah thanks, nice one :-) I take it you mean for deny?

It's better to post a link to a [url], usually from a version-control web-interface, if you want people to look at stuff. |

| One question. I have network filesystem which is supposed to be mounted on boot. It is listed in /etc/fstab. Things are working fine when I use net.* scripts. Without them, the filesystem is not mounted. I have to do it manually. Is there any simple way to tell dhcpcd to do it? I guess, I can create some script that dhcpcd executes when network is up, but rather relied on existing solution. |

There is /etc/init.d/netmount which is part of openrc.
I have rpcbind and fetchmail being started after dhcpcd comes up. And I guess it sould work for netmount as well.

You'll still need something broadcasting RA's. |
| Code: | | ip -family inet6 route add default via [IPv6-GW] dev eth0 |
Ok, dhcpcd.conf with static IPv6 address and noipv6rs option with above ip command at local startup script seem keep it working. With ipv6rs enabled it only works for a while, apparently some problem in OVH/Kimsufi network configuration. |
