When I try to run it in terminal, it is successful though there's no output. Its just goes back to prompt. When I miss some of the parametes, it shows an error so I concluded that if it goes back to prompt means no error. But when I check the web interface, it says "no output"...... Can this be a script problem? I chmod /usr/local/nagios/ to 710 and chown -R nagios.apache /usr/local/nagios to make sure permission is correct Here is the checkcommands.cfg check_ser command definition define command { command_name check-sip command_line $USER1$/check_ser -H $ARG1$ -U $ARG2$ -P $ARG3$ -w $ARG4$ -c $ARG5$ } Here is the bigger.cfg define service{ use generic-service host_name sip.nagios.com service_description SIP check_command check-sip!sip.nagios.com!sip:100@nagios.com!xyz123!50!80 } </div> <hr size=1>Ready for the edge of your seat? <a href="http://us.rd.yahoo.com/evt=48220/*http://tv.yahoo.com/">Check out tonight's top picks</a> on Yahoo!
