thank you Marc for your comment it was helpful :

[rxgz at DeepBlue ]$ service NetworkManager stop
Stopping NetworkManager daemon:                            [FAILED]
[rxgz at DeepBlue ]$ service NetworkManager restart
Stopping NetworkManager daemon:                            [FAILED]

[rxgz at DeepBlue ]$ /sbin/chkconfig --level 35 NetworkManager off
[rxgz at DeepBlue ]$ system-config-network

here I configured my network settings :
General: Nickname eth0
statically set IP addresses
Manual IP address settings
address:         192.168.1.2
subnet mask:     255.255.255.0
default gateway: 192.168.1.1


[rxgz at DeepBlue ]$ /etc/init.d/network start
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:                                [  OK  ]

Internet connection is not O.K.

here when I check the network settings the subnet mask is changed to 192.168.1.1 ??? 

address:         192.168.1.2
subnet mask:     192.168.1.1
default gateway: 192.168.1.1

this is really strange !
