How do I find my computer's IP address using t

Question

Every now and again, I need to start the Django development server, and have it viewable by other machines on my network, as described here:

http://docs.djangoproject.com/en/dev/ref/django-admin/#runserver

My machine’s IP address tends to change every now and again, so I’d like to have a little shell alias or something that spits out the manage.py command with my machine’s current IP address, maybe like this:

python manage.py runserver $(COMMAND TO FIND MY MACHINE’S IP ADDRESS GOES HERE):8000

Answer 1

This is a quick and dirty way, that works under OSX

/sbin/ifconfig | grep 'inet ' | grep -v '127.0.0.1' | head -n1 | awk '{print $2}'

Basically get all interfaces with an IPV4 address, skip localhost and then get the first interface.

Also, use path to ifconfig. I have seen to many shell script brake when used from ex. cron because of PATH failure.

Answer 2

Simple Command to fine IP Address with default interface.

ip route | grep src | awk -F 'src' '{print $NF; exit}' | awk '{print $1}'

Tested on All Unix OS

Answer 3

Here a solution to find the current IP address:

route -n get default|grep interface|awk ‘{ print $2 }’|xargs ipconfig getifaddr

tested on Mac only.

Answer 4

You might already be aware, but running

python manage.py runserver 0.0.0.0:8000

makes your machine visible to everyone on the network.

Is there a reason you'd need to specify your IP?

Answer 5

Folks are using character counts to pull the right columns from the ip address line, but using spaces as a delim makes this more scalable to different length ip addresses...

ifconfig en1 | grep inet | grep -v inet6 | cut -d" " -f2

Answer 6

Thi should work as well as other commands I've already seen:

ifconfig eth0 | grep inet | awk '{print $2}' | cut -d':' -f2

• Replace eth0 with the desired interface (eth0, eth1, wlan0...)
