Downgrade the plugin-package. nagios-plugins-1.3.1 seems by far the most 
portable and stable version of all the plugins.

You could also try the check_ping in 
http://oss.op5.se/nagios/op5plugins-2005-09-22.tar.gz

Strange. You could set it to 4110 if that makes anybody any happier. The 
nagios user can be disabled from logging in, and that'd be a safer setup 
than allowing the ping binary to keep on being setuid root.

If you take a look at the check_icmp code, you'll also notice that I 
take great pains of making sure everything is calculated properly, and 
that it drops privileges immediately after obtaining the socket. That is 
far more defensive than most regular ping implementations.
