If got this from a nice person at the LTSP IRC forum. Not tried it yet but going to

#!/bin/sh

EMAIL=$1
FILE=/var/run/ipwatch
DEV=eth1

NEWIP=`ifconfig $DEV | awk '/inet addr/ {print $2}' | cut -d: -f2`
[ -e $FILE ] && OLDIP=`cat $FILE`

if [ "$NEWIP" != "$OLDIP" ]; then
echo "New IP: $NEWIP" | mail -s "IP Changed" $EMAIL
echo $NEWIP > $FILE
echo "Notified by email ($EMAIL)"
fi

hi storskogen

What all are the settings should be done before executing the command

echo "New IP: $NEWIP" | mail -s "IP Changed" $EMAIL

Since i just tried the command here manually with the relevant data but no mail has come to my account.

Are there any steps to set up before sending mail. if yes then could you list out the steps?

Maybe I am missing something, but an email should only be sent if your IP address changed. If your IP didn't change, and you didn't get an email, it is working as designed.

EMAIL=$1 should be changed to EMAIL=yourmail@dot.com

first time you run the script:
sh ./ipnotify (if you name the file that)
it creates /var/run/ipwatch with your ip. change it to test the script and run it again.
I have to get my sendmail configured to be able to send it to any non-local user but thats another problem.

I put the script as cron job and running every hour

storskogen

and deek is right, it only send you an email if the ip has changed.
change the dev variable if you have any other than eth1 as your WAN eth

For me the problem is that I just want to send a simple mail
saying hello or something like that to a non local user eg sharon@yahoo.com.

This is what I want to know about, if it is to be done using sendmail.

How do i configure sendmail. I tried some methods of trying to configure it but no success.

I could like some help in configuring sendmail
