Can you try below command.
Code:
#service NetworkManager stop

If not..........
Code:
#ifconfig -a

// chose your interface. You can take as references below codes.
Code:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static or dhcp
IPADDR=192.168.10.9
NETMASK=255.255.255.0
DNS1=192.168.10.5
DNS2=192.168.10.4
#

Code:
# vi /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=unix.com.tr
GATEWAY=192.168.10.1

Code:
#vi /etc/resolv.conf

// 192.168.10.4-5

Code:
#/etc/init.d/network restart

If not you can use rc.local file when you reboot machine.

Code:
#vi /etc/rc.local
ifconfig  eth0  192.168.x.x netmask 255.255.255.x up
route add default gw 192.168.x.x dev eth0

It is a Bug in Fedora (I do not know in any other), that the resolv.conf file will not save if "networkmanager" is on.

This is the same thing I too did in my fedora-13 but with some slight difference.

Code:
# vi /var/systembackup/resolv.conf
nameserver x.x.x.x
nameserver y.y.y.y

then

Code:
#vi /etc/rc.local
cp -f vi /var/systembackup/resolv.conf /etc/
###OR you can do --> echo -e "nameserver x.x.x.x \nnameserver y.y.y.y" >> /etc/resolv.conf

This worked perfectly for me.
Good luck.
