i can not change IP on centos 5.3

my current network conf is

Code:

interface et0
IP 192.168.2.50
netmask 255.255.255.0
gw 192.168.2.1
bcast 192.168.1.255
mtu 1492

to change ip command is

Code:

ifconfig eth0 192.168.2.100 netmask 255.255.255.0 broadcast 192.168.2.255  mtu 1500

after above command i restarted network but no any changes

 

Either I'm having a dejavu or You're doubleposting.

Can't seem to find the other post now so here's the answer.
Try:

Code:

ifup eth0

All that will change the network settings only temporary.
To make a permanent change enter:

Code:

setup

and change the network settings.

 

Run

Code:

system-config-network

 

why can i not do it using command?

 

Or you can modify the configuration file directly at /etc/sysconfig/network-script/ifcfg-eth0

 

is that really should be et0
or eth0
?
