SIOCGIFADDR: Cannot assign requested address Error in python

Question

I want to set IP address by using python's subprocess module.

I was trying to use it like this:

from subprocess import call
call(["ifconfig", "eth0", "50.7.192.226", "netmask", "255.255.255.248", "broadcast", "50.7.192.231"])

When I run this script in my CentOS server I get this error:

SIOCGIFADDR: Cannot assign requested address
SIOCSIFBROADCAST: Cannot assign requested address
SIOCSIFBRDADDR: Cannot assign requested address

I couldn't figure out where this error came from.

Answer 1

You have the broadcast of a /23 if the network is 192.168.1.5

You may want to set broadcast of 192.168.1.255
