socket.gethostb yname(hostname) will return the IPv4 address of a host name.

Hi bvdet,

The

socket.gethostbyname(hostname)

command returns only loopback address 127.0.0.1 but it won't display actual IP address like '10.111.212.111 . Thats the reason i want to execute the below command in python.

Please let me know how can i execute the below command in python

sbin/ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' | 'cut -d: -f2 | awk '{ print $1}'

Regards,
Siva

How about this:

>>> socket.gethostbyname(socket.gethostname())
'10.0.0.3'
>>>

I'm on Win 7.

Hi

I got the answer for this.

import commands

commands.getoutput("/sbin/ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |cut -d: -f2 | awk '{ print $1}'")

will return the actual ip address like '10.120.11.123'

You can use the subprocess.chec k_output module to get the output from ifconfig and then parse that to find the inet rec. Note that on my system the rec starts with inet, not inet addr.
