Re: Trouble with ICS (was Re: Ad-hoc network: cannot ping other machine)

As far as I know, dhcpcd has always been capable of working as a
daemon. I guess NM just doesn't like it that way. I had it starting up
at boot and daemonizing per tutorials I had followed, but then again
the tutorials I had followed were aimed at using Gentoo's networking
structure - not tools like NM.

So I disabled dhcpcd from starting at boot. Now everything works
perfectly. I even have WPA encryption working over ad-hoc, and until
recently I had been led to believe that was impossible.

The only loose end is with ifnet. I had to disable it to get NM to
behave itself properly, so I'll report those issues to ifnet's
upstream.

Thank you very much for your help, Dan.
