In RedHat 9 the 169.254.0.0/16 gets added to the routing table on boot.
Probably to play nicely with windows boxen.  In Windows 2000+, if there
is no DHCP server available, an APIPA address (169.254.x.x) is


assigned.

Yep.  RedHat 9 introduces zeroconf, which you need to disable if you
don't want it.  Really, it's quite harmless, as the 169.254.x.x is a
private network space, and isn't routable over Internet links.


So, if it is harmless and even could improve communication with windows well probably I don't have any reason to get rid of it. Ok, as I go learning slowly and Im biologist not computer scientist please be patient.

With my simple network, simple questions: two boxes connected to a router which acts as dhcp server and firewall and connects to my dsl provider how can I set hostnames for the boxes that will map to the ip addresses leased by the dhcp server even if they could potentially change? I have tried by adding the parameter DHCP_HOSTNAME=myname to one of the /etc/sysconfig/network-scripts, but when I try, say, to ping one of the boxes it returns "unknown host". Adding the host name to /etc/hosts works but then starting sendmail at boot takes ages (probably because sendmail listens to localhost only?). Do I need internal DNS? Do I need to contact my ISP to give even internal names to my machines? which are the common workarounds for this?

The question is because I guess it is quite fundamental to solve this issue in order to establish other types of communication between the two machines, NFS for instance.

Thanks a lot for any tips.

Felipe.
