How to manually configure ethernet from Busybox

[Vesta]

Hi,

I solved the issue myself, the problem was obvious, it's shown in the log.
Sure, network was unreachable because the computer has no IP address assigned. 192.168.15.100 is IP address of PC.
I just had to configure a static IP address on a computer, if DHCP is not running. This solved problem.

Your tips is helpful, you're right, I don't need to specify broadcast when I am specifying netmask.
So:
# ifconfig eth0 192.168.15.1 netmask 255.255.255.0


And agree, this is not a Busybox bug. But hope it isn't too criminal ;)

Regards,
Alex
