13. You are configuring a Linux DHCP server. You have it setup and working (as Linux clients are getting ip addresses from the DHCP server fine) but some Windows 95 clients are not getting ip addresses properly from your DHCP server. What do you need to do?

+ j) i6 d: M3 g {. h' LExplanation: Windows 95 insists that the DHCPOFFER messages be sent to 255.255.255.255. Linux will send them to the broadcast address instead. Adding a host entry for the host 255.255.255.255 will trick Linux into working with the Windows 95 clients.
