Hi Wildman,
The below snippet seems to be fine, how can I specify to get the specific
wlan0 interface gateway IP in the below code snippet?
#########################
#!/usr/bin/env python
import socket
import struct
def get_gateway_ip():
try:
with open("/proc/net/route", "r") as f:
route = f.readlines()
except IOError:
return None
for line in route:
fields = line.strip().split()
if fields[1] != "00000000" or not int(fields[3], 16) & 2:
continue
gateway = socket.inet_ntoa(struct.pack("<L", int(fields[2], 16)))
break
return gateway
print get_gateway_ip()
#########################
Many Thanks in advance,
Srini
