Hello,
Thanks!
What I did , assuiming that I understood you right, was:
....
struct net_device* device;
struct net_device* deviceEth0;
struct in_device* in_dev;
struct in_ifaddr* if_info;
device = dev_get_by_name("eth0");
in_dev = (struct in_device *)device->ip_ptr;
if_info = in_dev->ifa_list;
........
and then traverse if_info (using it's ifa_next pointer) checking if
ifa_label is eth0:1
The ip address was in ifa_local.
This did work.
I hoped there is a more starightforward way. (maybe there is?)
Regards,
Amir

Hello,
This post has some relavance to a former question , which dealt with
getting
the ip of eth0 ;Now I must also get the IP on eth0:1 .
I do have an IP on both eth0 and eth0:1 , as running ifconfig shows
I try in init method of a module I wrote:
.........
struct net_device* device;
device = dev_get_by_name("eth0:1");
if (device == NULL)
{
printk("device is NULL\n");
}
...
I do get the "device is NULL message" after insmod my module.
Of course, because there is no such device as eth0:1. It's just an alias of
"eth0".
If you took a good look at the structure that is returned by
dev_get_by_name you would have noticed that the field containing the IP is
actually an array which holds all the addresses assigned to the interface
and it's aliases.
In short:
Use the Source, Luke!
