I have a Linux server running DHCP server and DNS server. I configured the DHCP server to send out the name-server address of the server. I can successfully browse the internet from the clients, so I know that external DNS resolution is working fine. I also see by the DHCP leases that the hostname is being sent by the clients. However, I cannot ping any of the Linux boxes from any machine by their hostname. Can anyone point me in the right direction? Thanks.
