Seems to me, that httpd should not be looking at /usr/share/snmp/.../.index
files? Notice that the .index file appears and for some reason httpd thinks
it should be looking at it!?!? I don't know what to make of it.
Here is what I got from selinuxtool:
================================================
Summary:
SELinux is preventing /usr/sbin/httpd "write" access to
/usr/share/snmp/mibs/.index.
Detailed Description:
SELinux denied access requested by httpd. /usr/share/snmp/mibs/.index
may be a
mislabeled. /usr/share/snmp/mibs/.index default SELinux type is
snmpd_var_lib_t,
but its current type is usr_t. Changing this file back to the default
type, may
fix your problem.
File contexts can be assigned to a file in the following ways.
* Files created in a directory receive the file context of the parent
directory by default.
* The SELinux policy might override the default label inherited from the
parent directory by specifying a process running in context A which
creates
a file in a directory labeled B will instead create the file with
label C.
An example of this would be the dhcp client running with the
dhclient_t type
and creating a file in the directory /etc. This file would normally
receive
the etc_t type due to parental inheritance but instead the file is
labeled
with the net_conf_t type because the SELinux policy specifies this.
* Users can change the file context on a file using tools such as
chcon, or
restorecon.
This file could have been mislabeled either by user error, or if an normally
confined application was run under the wrong domain.
However, this might also indicate a bug in SELinux because the file
should not
have been labeled with this type.
If you believe this is a bug, please file a bug report against this package.
Allowing Access:
You can restore the default system context to this file by executing the
restorecon command. restorecon '/usr/share/snmp/mibs/.index', if this
file is a
directory, you can recursively restore using restorecon -R
'/usr/share/snmp/mibs/.index'.
Fix Command:
/sbin/restorecon '/usr/share/snmp/mibs/.index'
