Do you still see the bug? Do you have any time to debug it a little bit? I still cannot reproduce it.

I'm sorry, as I said later in that bug, I cannot reproduce it. It turned out that my problems where misconfigurations (such as machine setup to ping itself while at the same time not replying to pings, overly restrictive firewalling etc).


This is also indicated by the error message which I got from watchdog (101 = ENETUNREACH = Network is unreachable). Now, the bug reporter got 106, which is probably EISCONN = Transport endpoint is already connected, which I've only seen either when calling connect twice on a socket, or when using sendto with a destination address on a connect():ed socket.

I've been through the latest sources trying to find something fishy that would cause the problems reported. The only thing I found which looks a bit weird is this:

watchdog.c, line 562, setsockopt uses hold as an argument, but hold has not been initialized, which might mean that broadcast packets are in fact not enabled, right?

That shouldn't account for the 106 error though, maybe the original bug has been fixed since it was reported?
