Description Paul Campbell 2011-01-12 15:02:45 UTC
SELinux is preventing /usr/sbin/sshd from 'module_request' accesses on the system Unknown.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow all domains to have the kernel load modules
Then you must tell SELinux about this by enabling the 'domain_kernel_load_modules' boolean.
setsebool -P domain_kernel_load_modules 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that sshd should be allowed module_request access on the Unknown system by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep /usr/sbin/sshd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
