Could anyone explain the following output of netstat -plunt
?
udp 0 0 0.0.0.0:58262 0.0.0.0:* 1163/avahi-daemon:
udp 0 0 0.0.0.0:17500 0.0.0.0:* 3779/dropbox:u
udp 0 0 0.0.0.0:5353 0.0.0.0:* 1163/avahi-daemon:
What does 0.0.0.0:* mean? Are all the ports being listened or something else?

The column after local address is "Foreign Address" - as these are UDP ports, and listening ports, there is no foreign address so a wildcard is shown.
I'm not sure if this would show the other end(s) if packets had been received as UDP is a connectionless protocol. Also as one-many comms is allowed a single foreign address could be misleading. So it may ALWAYS show the wildcard for udp.
