Hmm. That's an unexpected result. The next step would be to go one level higher and execute nagios' check_ping as the nagios user --
/path/to/nagios/libexec/check_ping -H 192.168.0.1 -w 3000.0,80% -c 5000.0,100% -p 1 Do you have SELinux enabled? Have you modified the default policies? I'd look for 'avc denied' messages related to nagios in /var/log/messages just to be safe or, as root, run 'audit2allow -l -i /var/log/messages -v'. -- Marc Powell > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:nagios-users- > [EMAIL PROTECTED] On Behalf Of Daniel Carvalho > Sent: Thursday, March 02, 2006 10:00 AM > To: nagios-users@lists.sourceforge.net > Subject: Re: [Nagios-users] nagios check-host-alive always down {Disarmed} > {Fraud?} > > Hi Marc, > > The command /bin/ping -n -U -w 10 -c 1 192.168.0.1 is executable for user > nagios.
