--- Comment #37 from Zebediah Figura <z.figura12 at gmail.com> ---
I'm adjusting the title, since it's misleading. As far as I understand
SOCK_DGRAM + IPPROTO_ICMP actually does sufficiently work on Linux (Damjan
claims it is "completely broken", which seems odd seeing as `wine ping` works
fine.) The problem is, as far as I'm aware, this is *also* forbidden by default
on some distributions, including Debian, via the "net.ipv4.ping_group_range"
sysctl.
Should we just require that sysctl to be set for Wine? Is it reasonable to try
to fall back to ping(1)? I don't see any other way to achieve what we want...
The linked download no longer works on Windows (i.e. it gives the same "no
internet detected" message; probably the service died), so I'm removing that.
