Ifconfig does not show my IP [closed]

When i'm putting the code on: ifconfig

ifconfig results in a terminal shows:

eth0 Link encap:Ethernet HWaddr: f8:a9:63:64:3f:1c
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets: 0 errors:0 dropped: 0 overruns: 0 frame: 0
TX packets: 0 errors:0 dropped: 0 overruns: 0 carrier: 0
colisions: 0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) 

Does not show my Itnet addr, bcast and mask!

What's that supposed to mean?

The interface eth0 is up, so the underlying device is found. There no IP address associated to this interface.

Assign an ip address manually:

$ sudo ifconfig eth0 w.x.y.z

Or contact the DHCP server, if it exists, and let it provides an ip address for the interface:

$ sudo dhclient -v eth0

If something goes wrong, dhclient will print error messages. They should be used to troubleshoot.

If the system just booted, then there could be a missing configuration or a mistake in interfaces configuration.

In order to fix issues of interfaces setting at boot or If you would like to make the settings persistent over the reboot:

• man interfaces
• edit /etc/network/interfaces file
