get localhost IP address from Linux kernel


Hi,

I would like to get the localhost IP address from within the Linux kernel module loaded.(not the 127.0.0.1 but the IP address assigned to the eth interface)

any way to go about this?

Well, if you mean your IP address on your local network:

Code:
dave@dave:~$ ifconfig
will return all current network interfaces, with all relevant info.

This:

Code:
dave@dave:~$ ifconfig | grep inet
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          inet addr:192.168.1.10  Bcast:255.255.255.255  Mask:255.255.255.0
          inet6 addr: fe80::219:d2ff:fe88:b87f/64 Scope:Link
is more specific, and for me the relevant line in the output is the third line, with the IP address!

Hope that helps.

I realize that this thread is quite old, but I will update it with my findings for future visitors.

Now I have no idea wether this is safe or not, but it is at least one way of finding your local IP from kernel-space:
