Hi All,

Before installing OSX10.1.2, I could determine the current IP address of my cable connection from the command-line via:

/usr/sbin/ipconfig getifaddr en0

As of 10.1.2, this now gives me an error:

get if addr en0 failed, (os/kern) failure

Any idea what is going on? Any suggestions on other command-line ways to determine the IP address?

Thanks.

ifconfig -a
returns all ip addresses and other information about all your network devices
or type "man ifconfig" for more info

If you want just the IP address, then do:

<font face = "courier">ifconfig -a | grep inet | grep -v 127.0.0.1|awk '{print $2}'</font>

This way you filter out all the less important info from the ifconfig command.

Actually, I find that the following returns the IP address (numbers only)

ifconfig en0 | awk '/inet/{print $2}'

and since it involves only a single call to awk, (no grep) it might be a little faster. HTH

Whilst a couple of workarounds have been posted below, this is a bug. Please report it to apple, so it can be fixed.

I think this may be related to nettools now being out of sync with the kernel, but not 100% sure.

Cheers.

Yet another way of getting the IP address(es):

AppleSystemProfiler | grep IP

That's weird - when did AppleSystemProfiler become a CL tool?

[Glasspusher]

I don't know when AppleSystemProfiler became a CL tool, but make sure you capitalize the ASP! It will work in situations where the GUI ASP will crash and tell you nothing- at least the CLI ASP will crank out info until it fails, and the info that is left can be read after it goes south, if it does. A handy thing to know. I use it more than the GUI one...

at least since macos x public beta (and probably before).

[Arkham_c]

That is an awesome tip!

I can think of all sorts of good uses for that. Here are the command-line options for it:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
[dshaw@iceman ~/Downloads] AppleSystemProfiler -h
usage: AppleSystemProfiler [-[adefhmopuw]]
where options are:
-a show all information (the default if no options specified)
-d show drive information (location and volumes connected)
-e show Ethernet information (similar to ifconfig)
-f show FireWire information
-h show this usage information
-m show memory information (total amount, how much is in each slot)
-o show hardware summary (information not shown by d, e, f, m, p, and u options)
-p show PCI card information
-u show USB information
-w &lt;path&gt; Use the code bundle from &lt;path&gt;. Default is /Applications/Utilties/Apple System Profiler.app/
</font>[/code]

This also found my Zip drive.

Very cool tool from the command line indeed!

You're using en1 interface, probably. A good way to get the ip address is:

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>
#!/bin/sh
ifconfig en1 | awk '/inet/{print $<font color = blue>2</font>}'
ifconfig -a | grep inet | grep -v <font color = blue>127.0</font>.<font color = blue>0.1</font>|awk '{print $<font color = blue>2</font>}'
</font>[/code]

Yep, me too. Therefore to fix that, we type:

<font face = "courier">AppleSystemProfiler -e | grep IP</font>

Voila!
