Nagios Support Forum

hi,
I have some attendance devices and want to monitor them via ping.
nagios server and device are in the same network.(no firewall/router hop)
the problem is that although ping command correctly says host is up but check_icmp says it down!!!!
I can not ping non of Attendance device via check_icmp/check_host.I also have no problem with other device type.


Here is ping and check_icmp output,

check_icmp v1.5 (nagios-plugins 1.5)

You might try installing the latest version of the plugins, as there have been some significant changes in 2.0

http://nagios-plugins.org/

TNX for your reply but I have the same error on check_icmp v2.0 (monitoring-plugins 2.0)

Well, we do not support monitoring plugins. We do support Nagios Plugins - I have a suspicion you will still have the issue, but can you try with:
http://www.nagios.org/download/plugins
Can we work with this issue on github?
