thank you how can I put the name server in dhcpd.conf for the client as I use ISP nameserver? this name server has to change when I change other ISP too
run your own local DNS caching server, and give the DHCP clients 192.168.0.1 or whatever your local network gateway IP is.

yum install caching-nameserver chkconfig named on service named start
will work if that's all you want. But don't install that package if you also want it to act as a primary server for your own local names (and if you have more than a few machines you probably do want that).

for your use, dnsmasq would do nicely. with the rpmforge repo configured...
# yum install dnsmasq # chkconfig dnsmasq on # service dnsmasq start
*done*
dnsmasq has some configuration options in /etc/dnsmasq.conf as well as man pages explaining more. there's some notes on it here, http://www.thekelleys.org.uk/dnsmasq/doc.html

whats wrong with the dnsmasq already included in C5 ? ( I am guessing the target is c5 )
# yum install dnsmasq # chkconfig dnsmasq on # service dnsmasq start
Why not just use the caching-nameserver ?

oh is it? I did a rpm -qi and saw your name and assumed it was from rpmforge.

isn't that a canned bind configuration? ah, yeah, thats what the package info file says it is.
bind is a lot more complex than dnsmasq. dnsmasq uses /etc/resolv.conf for forwarded lookups, while a caching bind server either uses a statically configured forwarder, or a root cache zone, and running a root cache zone on a intermittently connected system ('different ISPs') isn't a good idea.
dnsmasq will also serve local clients with dns using entries in your /etc/hosts file, which can be handy when you have a few static hosts on a small masqueraded network.

There are db based nameservers such as MyDNS or djbdns or pdns. MySQL db replication can replicate zones to other machines and it has an web interface option.
pdns is authoritative only, not caching. pdns-recursor is caching.
yum search pdns for ldap, db, geo, .... and i thought a web interface.
