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

[Patrick McMunn <doctorwhoguy gmail com>]

I tried connecting on my laptop with DHCP, link-local, manual, and
shared modes in IPv4 Address. I *was* able to connect in shared mode
and by manual configuration, but I couldn't browse the internet. At
one point on my laptop, I was able to browse only to google.com when I
tried using a manual config, but even that stopped working (I stopped
using Openresolv on my desktop to see if NetworkManager would stop
overwriting /etc/resolv.conf, and I later found out that at some point
in my testing dhcpcd had overwritten /etc/resolv.conf on my desktop,
so the nameserver list was blank).

Anyway, here are the relevant parts of /var/log/messages from the
laptop: first when trying DHCP and then, after a reboot, trying
link-local.
