Nagios Support Forum

Hi,

That's a pretty common problem
You've had wrong file permissions set for the check_icmp script (located in libexec directory).
This one is beeing used for hosts availability checking (in standard configuration).
It needs the "set user or group ID on execution" bit set for the owner of the file and root:root ownership to work properly (i.e: root:root r-sr-xr-x)

And that's it
By the way - the same file permissions are required for the check_dhcp script

Take care

hi nscott,

I have tried the NRPE step by step instructions,

http://www.utahsysadmin.com/2008/03/14/ ... olaris-10/

however now I get the same error which I got before "Warning: This plugin must be either run as root or setuid"

I even tried the earlier step but no joy this time ... it still remains the same cant get it to work ...

hi pzusa - if you can please let me know how to change the wrong file permissions it would help me out i guess
Please help

thanks

Running .A-subcomponents is not fixing the permissions? Thats really strange. Whats the ls -l on your libexec directory?

hi nscott,

Yeah running ./A-subcomponents doesnt fix permissions anymore and it says " Subcomponents already configured- skipping "

please find the output below

DOH! I forgot, when you're in the /tmp/nagiosxi directory, you'll need to do this:

rm installed.subcomponents -f

Then run the A-subcomponents script again

Login as root and cd to the /usr/local/nagios/libexec directory.
Than run: chmod u+s check_icmp
This should fix the problem.
