This file is OWNED by "root", not RUN as "root". Your Nagios process is probably running as "nagios". Therefore "check_icmp" is run as "nagios", not "root" by the Nagios process. My understanding is that you should change the file's permission and set the "setuid bit" in order to allow "nagios" to run this file as "root". -- Mathieu ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
