I try to have a static ip adress on an host.

I execute the following commands : 

$ ip address eth0 10.4.1.15 netmask 255.255.255.0

$ route add default gw 10.4.1.5

But later my IP address changes on 10.4.1.241 unless I have commented the request command in dhcplient.conf and I have put into /etc/network/interfaces the following: 

iface eth0 inet static
address 10.4.1.14
netmask 255.255.255.0
gateway 10.4.1.5

Please help me I don't understand why my ip changes ?

Thanks in advance.

/etc/network/interfaces holds your default configuration... so if you need a permanent static IP, put it in there like this:

iface eth0 inet static
address <THE IP YOU WANT>
netmask 255.255.255.0
gateway <THE IP OF YOUR GATEWAY (Usually your router)>

The commands you executed only adjusts your configuration temporarily.

You also need to remove the line for dhcp, or at least you should. iface eth0 inet dhcp # <== Remove this – peelman Jul 21 '10 at 21:44
I don't see the difference than I have made – user32433 Jul 22 '10 at 6:46
@user32433 - Your IP shouldn't change when that is in your interfaces file. – BloodPhilia Jul 22 '10 at 14:43
