Hi,

In using the Boost.Asio library, the Udp::Socket->send_to() function
throws an error if the endpoint is unreachable.  I thought in udp
datagrams its a send and forget mentality.  The send_to function would
send the message even if the endpoint was unreachable.  Is there a
setting I need to use for this to work?

This probably means you don't have a route to the target host,
so your kernel returns with error from local TCP stack without
actually putting packet on the wire.

Hope this helps.

I thought udp didn't need a route to the target host.  As long as there is a connection to a hub the socket would send the data out.  Don't a route to the target host mean tcp?
