I've asked this question on Ask Ubuntu regarding my system showing up by default in networks. The answer I've accepted says that as long as I'm not using
samba components, I won't show up wherever the computers on the network are displayed. The only possible exception being
zeroconf in the absence of DHCP server.
My question is, why does
zeroconf make my computer vulnerable to discovery through networks? Is it applicable to wireless networks?
I've made a rough guess about
zeroconf, using the answer on Ask Ubuntu as basis, that the address block used for self-configuration is the same across all systems - so in the absence of DHCP server, searching for systems on the network using the
zeroconf address block as reference would make it easier to find computers on the network.
Finally, I'd like to iterate that I'm already aware that no matter what I do I'm still open to sniffing, so don't bother trolling with it.
