hi,nagios policy is not used in RHEL4. It should run unconfined_t. We are only supporting the subset of network daemons in targeted policy.
there is a nagios_log_t and used in nagios.fc but never defined (missing). so when we try to apply it we got these errors:
---------------------------------------------

how can i fix it?
dan could you create updated rpms which fix it in ftp://people.redhat.com/dwalsh/SELinux/RHEL4/ ?:-)
yours.
Using strict or other policies in RHEL4 requires a separate support contract, professional services engagement.
ok. i only think that if nagios_log_t used in the current selinux-policy-targeted than (in nagios.fc) than it should have to be defined also. but it's definition currently missing from selinux-policy-targeted, which is imho a bug. that's what i'd like to report.
another thing even if nagios run in unconfined_t is ok since the log files can be generated and the daemon is running, but the web interface of nagios not working since it's try to read it's log files under /var/log/nagios which is currently var_log_t (inherited from it's parent). so currently i've a few options:
- add a local.te as:
allow httpd_sys_script_t var_log_t:dir search;
allow httpd_sys_script_t var_log_t:file { getattr read };
- change /var/log/nagios to httpd_sys_content_t and add only
allow httpd_sys_script_t var_log_t:dir search;
- change /var/log/nagios to nagios_log_t and add
allow httpd_sys_script_t var_log_t:dir search;
allow httpd_sys_script_t nagios_log_t:file { getattr read };
and imho the best solution would be to add this last one to the global policy.
yours.
just my 2c.
