Ping problems revisited

[Hernández López Carlos]

Hello all, 
 
I´m new with Argus and have some problems configuring the ping service. I´m trying to create a group to monitoring a set of servers via ping, the problem is that "all servers start off as up and then all go down,  then stay down even though they are all up!!"
 
My fping its setuid root: 
 
$ ls -l /usr/local/sbin/fping
-rwsr-xr-x  1 root root 47301 Dec 13 12:50 /usr/local/sbin/fping
 

and my config file is something  like:

 .....

 .....

 .....

            Group "NetStat" {

                        frecuency: 300

 

                        Host "Subnet 6" {

                        hostname:170.70.6.146

                        Service Ping

                        }

 

                        Host "Subnet 49" {

                        hostname:170.70.49.142

                        Service Ping

                        }

 

                        Host "Subnet 91" {

                        hostname:170.70.91.27

                        Service Ping

                        }

}

 

Any ideas?

 

Thanks

 

Carlos
