the netconfig , ifconfig command are not working here.
so can any one tell me what is the command for configuring ip address and , the command for seeing the ipaddress issued.

ifconfig is the command you want:

Code:

ifconfig &#91;device&#93; &#91;my.static.ip.addr&#93; netmask &#91;my.net.work.mask&#93; up

for example:

Code:

ifconfig eth0 10.1.7.13 netmask 255.255.255.0 up

Then if you want to see the current network configuration:

Code:

ifconfig

hi Kode,
thanks for replying to my query, what is the command for permanently entering the ip address through command line,
the ifconfig after restaring goes away.

Just put the ifconfig line in a startup script so it's run on boot. That's all every other distro does.

Distros I've worked with read the network setting from a configuration file, namely /etc/network/interfaces (<- on Debian and related distros; might be elsewhere in /etc for others). See the man page for interfaces. A quick summary is that in this file, you'll see something like this:

Code:

iface eth0 inet dhcp

You just need to change dhcp to static, then on the next 3 lines specify the address, netmask, and gateway. I think the gateway isn't strictly needed, but putting your router's address there doesn't hurt.

How do I open interfaces?? When I ls in /etc/network I see it there, but when i try and get into it, it says its not a directory... Is there a program that I need to use to open it?

route add default gw <ip number>

@maximum720:
As root, use a text editor like nano to open the file:

Code:

nano /etc/network/interfaces

he below information is for how to specify and adjust your network settings through the command prompt. Changing your network settings will require root access.

1. Get to the command prompt.
2. Move to the /etc/sysconfig/network directory.
3. Edit the interfaces file and adjust your network settings in this file.
And for windows you can chk the ip address ip-details.com
