GETTING IPADDRESS

Hemant_2 — Fri, 16 Nov 2001 09:53:46 GMT

Hi,
When I do "who am I -R "the output gives me my terminal no. and the hostname (if defined in /etc/hosts) or ipaddress if not defined in /etc/hosts file.
Are there any other ways by which I can get the ipaddress for the connection ?

Regards
Hemant

"who -T" will give you the IP addresses of all users logged in.
You can grep for your login name / tty from this list, if you want.

Hi,
you can try :
who -u | grep $(who am i| awk '{ print $2 }')

Since this is -probably- related to setting the display, you can get just the IP address from:

who am i -u | awk '{print $8}'

Hi,

Do a who -R and and filter out the hostname. with nslookup you should be able to get te ip-adress.

Hi All,
Thanks for you very fast replies but I want to get ipaddress without using "who" or /etc/hosts for a session.
The situation is like this,
In /etc/hosts file 2 different ip address have same hostname but who am i will always show me this common "hostname" so I need to avoid using "who" and /etc/hosts file.
So based on say terminal name which will be different for both.
That is what I meant.

I wrote the following C program to get around a similar problem - I didn't want to reverse lookup the IP address but there's no way to tell 'who' not to do this.

This program emulates a 'who -u' by reading the utmpx file and displaying a list of users currently logged in, but prints the IP address as stored in the utmpx entry instead of resolving the hostname.

Compile as follows (you'll need gcc or the ANSI C compiler)

$ cc -Ae mywho.c -o mywho

Have fun...

See man last:

i.e:

last -20 -R pts/ty

Try

ip=`env | grep TERM`
nslookup $ip

Would getip command be useful here?

getip hostname

returns the IP address of the host.
