    Home network hostname resolutions

    On my home network I setup a Slackware 10.2 instance as a DHCP client to my cable modem and a DHCP server to my home network. I got the packet forwarding and DNS forwarding working, however, I can't ping my other local machines by their hostnames. I have to use IP addresses for everything. How can I setup my network so I can use hostnames instead of IPs on my local network? I'm using the 192.168.5.0 range. When I'm plugged into my old dlink router all the hostnames work.

    Thumbs up

    The simplest way to do it, if you only have a small
    number of hosts, is to edit the /etc/hosts file on each
    computer.

    Code:
    #
# hosts		This file describes a number of hostname-to-address
#		mappings for the TCP/IP subsystem.  It is mostly
#		used at boot time, when no name servers are running.
#		On small systems, this file can be used instead of a
#		"named" name server.  Just add the names, addresses
#		and any aliases to this file...
#
# By the way, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1
# should NEVER be named with the name of the machine.  It causes problems
# for some (stupid) programs, irc and reputedly talk. :^)
#

# For loopbacking.
127.0.0.1		  localhost
192.168.1.5	        blue.localdomain        blue
192.168.1.2		coffee.localdomain    coffee
192.168.1.3		genius.localdomain    genius
192.168.1.4		moron.localdomain    moron
192.168.1.6		rcgreen.localdomain  rcgreen
# End of hosts.
    List the adderss if each host, and its hostname

    Also make sure that /etc/host.conf has a line that says

    Code:
    order hosts, bind
    On Windows machines the hosts file is usually in C:\WINDOWS\SYSTEM32\DRIVERS\ETC, and there
    is no host.conf

    If I setup my slackware box as a DNS server too, isn't there a way that the DHCP server can interface with the DNS server to automatically add hostnames and IPs? If someone else hooks up a laptop, I don't want to have to add their IP/hostname to all my servers manually.

    Has anyone gotten their DHCP server to automatically update a DNS server?
