setuid bit missing on check_icmp

[Julius Bloch]

I have installed nagios2 on ubuntu 7.10.
I am using check_icmp for PING checks. In the default installation the writes for the check_icpm in /usr/lib/nagios/plugins/ are wrong. The check_icmp binary needs chmod +s, because it works with raw sockets.
The default rights are only:
 ls -la check_icmp
-rwxr-xr-x 1 root root 30524 2007-10-22 16:17 check_icmp

dpkg -l nagios-plugins-basic

Confirmed in hardy's 1.4.11-1ubuntu1.

It's this way on purpose (also for check_dhcp). See /usr/share/doc/nagios-plugins/README.Debian. If you want to be able to run these checks, you can set the proper permissions override, as described in the readme, using dpkg-statoverride. The plugins are shipped as a safe default so as not to install an SUID-root binary unless the administrator explicitly enables it.
