[GNUnet-developers] Binding to multiple IP addresses

[Nathan Lutchansky]

After taking a look at the transport infrastructure in the GNUnet CVS, it 
appears that the core assumes that each transport will create no more than 
one HELO message.  This artificially limits us to one addr/port binding 
with the UDP transport, preventing a GNUnet instance from advertising 
multiple IP addresses.  Is there a reason this was done, or was it just an 
artifact of the chosen API?

Also, I notice that UDP binds are done to the INADDR_ANY address, even 
though we know the correct address we should be sourcing packets from.  Is 
there any reason the UDP transport does not bind to the address given by 
getPublicIPAddress() in passivesock()?  I can think of several reasons 
a wildcard bind would cause problems, but can think of no reasons a 
specific bind would hurt anything...  -Nathan
