check my ip address instead of my dns name

[Moises Kaplan]

I would like to know the command to check my ip address.
When I use who -u (or who -R) I get my dns name instead.

thanks, mk

How about
getip $(who -u | awk '{print $NF}')
?

[Moises Kaplan]

thanls a.clay,

but I get an error message:
Usage: getip host

[A. Clay Stephenson]

Then I suspect that you made a typing booboo because it works for me.

What is your EXACT output of who -u?

[Moises Kaplan]

I just copy and pasted.

this is the line for who am i -u

moises pts/tk Sep 18 17:55 . 8480 mn_064.national-lumber.com

thanks

[A. Clay Stephenson · Accepted solution]

OK, do this for me:

getip mn_064.national-lumber.com

Does that work?


Now try,
who -u | awk '{print $NF}'

Does that output mn_064.national-lumber.com?

The problem is probably a result of the illegal "_" character in your hostname. If you play by the DNS rules, "_"'s are not allowed.

it didn't work

any other sugestion?

[Moises Kaplan]

sorry, I forgot to tell you, I'm at a pc w/a fix IP address. I'm not inquiring about the host, but about my own IP address

thanks, mk

> getip $(who -u | awk '{print $NF}')

dy # getip $(who -u | awk '{print $NF}')
Usage: getip host

dy # who -u
root pts/0 Sep 18 17:03 . 1180 alp-l.antinode.org
root console Sep 18 17:04 0:02 2146 system console

dy # who -mu
root pts/0 Sep 18 17:03 . 1180 alp-l.antinode.org

Or, "who am i -u".

dy # getip $(who -mu | awk '{print $NF}')
10.0.0.9

Yes. Say exactly what you did, and,
exactly, what happened when you did it.
Saying "it didn't work" is about as useless
as saying nothing.

While logged in to your unix box type:

ping `hostname`

where ` is the key in the top left corner of the keyboard. The result will display the ip address.

>Mark: where ` is the key in the top left corner of the keyboard.

If you used the following you wouldn't have to explain it: :-)
$ ping $(hostname)

[Dennis Handly]

Of course you can save even more steps by:
$ nslookup $(hostname)

[rmueller58]

look at the last column.
who am i -u

[Sp4admin]

Hello,

I agree with Dennis, why not just do a nslookup on the hostname. You also can check the /etc/rc.config.d/netconf file or the /etc/hosts.

sp,
