Hello,
I am running Icinga2 and /bin/ping is attempting to append to /var/lib/icinga2/api/log/current - which is being denied by selinux.
CentOS 6.6
icinga2-common-2.3.4-1.snapshot201504272021.el6.x86_64
icinga2-bin-2.3.4-1.snapshot201504272021.el6.x86_64

***** Plugin leaks (86.2 confidence) suggests ******************************
If you want to ignore ping trying to append access the current file, because you believe it should not need this access.
Then you should report this as a bug.
You can generate a local policy module to dontaudit this access.
Do
# grep /bin/ping /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp
***** Plugin catchall (14.7 confidence) suggests ***************************
If you believe that ping should be allowed append access on the current file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep ping /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
[root@server ~]# grep ping /var/log/audit/audit.log | audit2allow
#============= ping_t ==============
allow ping_t var_lib_t:file append;
I was able to 'fix' it with (this seemed better than allowing ping to append to all var_lib_t files):
[root@server ~]# semanage fcontext -a -t var_log_t "/var/lib/icinga2/api/log(/.*)?"
[root@server ~]# restorecon -Rv /var/lib/icinga2/api/log
Please let me know if this information should be provided to the icinga team rather than here, or if any other information would be useful.
Thanks,
Lee Clemens
