I had a dynamic dns service at one time, but now I use a script to tell me
if my ip has changed. It runs about ever 5 minutes using cron.
[EMAIL PROTECTED] bin]# cat checkip.sh
#!/bin/bash
# I have this program running in /etc/crontab with the following
configuration:
# * * * * * root /usr/local/bin/newip
#
date=`date`
ifconfig eth0 | grep "inet " | cut -f12 -d" " > /usr/local/bin/.newip
if diff /usr/local/bin/.newip /usr/local/bin/.currentip;
then
exit 0;
else
cat /usr/local/bin/.newip > /usr/local/bin/.currentip;
cat /usr/local/bin/.currentip > /usr/local/bin/.report
date >> /usr/local/bin/.report
mail -s "New IP on $date"[EMAIL PROTECTED] <
/usr/local/bin/.report;
echo "different ip"
rm -f /usr/local/bin/.report
exit 0
fi
