Thank you for your post otheus, sorry this is late, just been away for a couple of days. Well what have done so far, is to use the time, and not the ip address in shell script, I check the database every 5 mins to see if the time registered is not ever a certain amount of time.

This is because the page are time are been updated, and am running a cron job every 5mins to check.

the down side to this is if the I have a lot of active user, it means that it will have to go through a lot of data and its not instant as well.

i have read of using sockets in php, does anyone have the experience for that, thank you for your help.
