You might consider setting the local users HOSTNAME environmental variable to their IP address. When they log in remotely the DISPLAY variable willl be set using HOSTNAME (which will now be the IP address). When they execute an X process it will work because the IP address is in the DISPLAY variable and not the name. This eliminates the DNS problem.

This works, of course:

export DISPLAY=111.222.333.444:0.0

What it's equivalent in Digi Unix?

I tried to use netstat -n -e , but it gives me illegal option thingy. It so happens that Digi Unix doesn't have -e option with netstat. What is -e for? I think in order to find the IP of the user logged in one can pipe the users from who to netstat... Maybe that will work!

In my SCO Unixware system I have command like last. Try something like
last | grep <your_name>| awk ' {print $3}'

well, I have found one way to determine it by loking up host tables.
This is the script I am now using:
Code:
TTY=`who am i | awk '{ print $2 }'`
HOSTNAME=`w | grep $TTY | awk '{ print $3 }'`
IP=`host $HOSTNAME | awk '{ print $4 }'`
echo $IP

Data

Hi,

I have the same issue, it seems that the second line of ur script gives the time. Can u tell me the exact working of this script?

Also, is it possible to find who is logged on in the remote machine?

Thanks,

This script works as follows:
Code:
TTY=`who am i | awk '{ print $2 }'`
# TTY is second field of my "who am i" command

HOSTNAME=`w | grep $TTY | awk '{ print $3 }'`
#HOSTNAME is then the third field of the "w" command
#Which is the Hostname of the machine logged in FROM.

IP=`host $HOSTNAME | awk '{ print $4 }'`
#IP is then the IP number of the machine that made the 
#connection, looked up from the host tables.
#for me this is the fourth field.


echo $IP
#Print IP number to screen.

You may need to change some of the awk commands to different fields, as these are only what works on my system, Redhat 7.0.
try running it manually, line by line to find out what changes need to be made.

Hi,
Thanks for the explanation.

But these things dont work for a Solaris/HP/AIX box.

The idea of passing the DISPLAY variable is good, we can know the IP Address.

Is it possible to pass the LOGNAME variable? I also need to find the user logged in the other machine. I tried exporting LOGNAME variable, as I do with DISPLAY, but it doesnt work. Unix gurus can u tell me what i should do? Smilie

Thanks
