Hi, all,
I got an additional entry when I run “netstat –rn” on my fedora host, an “169.254.0.0 …” entry appears without being invited. I know that 169.254.0.0/16 is a private address block for some kind of special purposes, and it appears in “ifup” script, But my question is: what does this entry mean? And How to get rid of it if it does nothing except bring security holes? Since it is routable now through my hosts’ exneral interface, ridicules..
It means you have an additional network card, without an active connection. The card tries to retrieve an IP address from a DHCP server which is supposedly not present. Then this address will be assigned to it.
And chances are, the DHCP server is "not present" because there is no network cable plugged into that interface. In which case don't worry about routing over it :-). Use
/sbin/ifconfig
as root to list all your adapters (in case you didn't already know) and figure out which is this one.
