Hi Mike,

u_l_i_t is explicitly set to 0 in the Debian packages.

It doesn't comment about any confiruation in the debug file.

I have set:
debug_level=34                      
debug_verbosity=2                      
debug_file=/var/lib/nagios3/nagios.debug                      
max_debug_file_size=1000000

but it isnot too informative. Neither does it say how the
configuration directives have been processed, nor does it comment
about setting any environment variables (not even the NAGIOS_PLUGIN
that _is_ passed to the environment). It does dump the raw
notification command, but I know what Nagios does with that.

At this time, I prefer to stick with what my distribution delivers and
supports. Are there any security relevant things that could convince
me to take the burden of doing my own security support, or is the
environment issue fixed in Nagios 3.2?

Greetings
Marc
