Broadcast packets
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I run samba on my firewall (because it's my print server as well), and have
set it to listen to the internal interface only. But I get this in netstat:
udp 0 0 0.0.0.0:138 0.0.0.0:*
udp 0 0 0.0.0.0:137 0.0.0.0:*
I posted a bug to the debian package and the maintainer looked into the
problem and awnsered saying that for a program to receive broadcast packets
it must listen to all interfaces. Is this the case or can you have to bind
to, say, 192.168.1.0 only?
Can someone here explain the mechanics of broadcast packets and daemons that
use them?
Sorry if this is a bit offtopic,
Pedro.
