I don't think fsockopen's failure to open a socket will "kill" a PHP script... Show us source code for that bit, and the loop you use to visit all the PC's... Also be sure you are setting a reasonable time-out on the fsockopen (http://php.net/fsockopen) as well as on PHP itself (http://php.net/set_time_limit) Try adding as much error-checking code as you can around the fsockopen functions calls, and log the stuff to a file or something where you can get it. http://php.net/error_log -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
