I really dislike all the "helpful" addons like avahi/mdns and rpc.statd
that scan and listen on every network you connect to.

Windows has a lot more of this type of thing but one of the things MS
got right was the application level firewall and the distinciton between
public and private networks, where when you connect to a new network in
vista and above it asks you what type it is and restricts communication
accordingly vs helpfully scanning for printers on a public wifi network.

"rpc.statd A daemon that listens for reboot notifications from other
hosts, and manages the list of hosts to be notified when the local
system reboots"

I see no reason as to why this should be turned on or even installed by
default and the same goes for avahi - for the majority of users both of
them are nothing more than a potential security issue and a waste of memory.
