Customizing dhcpcd and NetworkManager 0.7

damjan · 2008-12-27 15:53:31

Since the upgrade of NetworkManager to 0.7 (from /testing/), it now uses dhcpcd instead of the DBus dhcp daemon (that called dhclient).

So previously I had dhclient set, through /etc/dhclient.conf, so that it always prepends "nameserver 127.0.0.1" and also to add a custom "search ..." domain in /etc/resolv.conf.

But now with dhcpcd I don't know how to accomplish the same thing. dhcpcd by itself should at least prepend /etc/resolv.conf.head when it creates /etc/resolv.conf, but NetworkManager calls dhcpcd itself overriding anything in /etc/dhcpcd.conf, and it seems that NetworkManager writes /etc/resolv.conf in the end.

So my question is, how do I cuztomize /etc/resolv.conf when using NetworkManager 0.7 and dhcpcd?

anyone?

Whatever you put in /etc/resolv.conf.head file should always be placed at the top of the resolv.conf created by dhcpcd; similarly whatever you have in /etc/resolv.conf.tail will be placed at the end of the file.

@fwojciec, that's how dhcpcd works by default... but NetworkManager overrides that

Sorry, I didn't read your post carefully enough...
No idea about NetworkManager -- can't you use something else instead?

Edit Connections -> Wireless(/Wired?) -> Your network -> IPv4 Settings...

Method -- Automatic (DHCP) address only
And enter DNS servers into the "DNS Servers" field like so: 127.0.0.1, 192.168.1.1 (and search domain below, if you want it)

I checked it on my system and it works like it should.

This is with network manager from [testing].

Heh.. I would never think to check that the GUI supports this

.. although.. this is still suboptimal, I'd have to do this with every wifi network I plan to connect ever.

You can do the same I did: recompile both libnetworkmanager and networkmanager with dhclient support ( --with-dhcp-client=dhclient ).

EDIT: I uploaded PKGBUILDs for both libnetworkmanager and networkmanager using dhclient to AUR, in case you're lazy.
They're named libnetworkmanager-dhclient and networkmanager-dhclient.
