Description of problem: The problem happens when upsmon is installed and started and selinux is enabled on the system SELinux is preventing /usr/sbin/upsmon from 'open' accesses on the chr_file /dev/urandom. ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If you want to allow authlogin to nsswitch use ldap Then you must tell SELinux about this by enabling the 'authlogin_nsswitch_use_ldap' boolean. You can read 'None' man page for more details. Do setsebool -P authlogin_nsswitch_use_ldap 1 ***** Plugin catchall_boolean (47.5 confidence) suggests ****************** If you want to allow global to ssp Then you must tell SELinux about this by enabling the 'global_ssp' boolean. You can read 'None' man page for more details. Do setsebool -P global_ssp 1 ***** Plugin catchall (6.38 confidence) suggests ************************** If you believe that upsmon should be allowed open access on the urandom chr_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 upsmon /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:nut_upsmon_t:s0 Target Context system_u:object_r:urandom_device_t:s0 Target Objects /dev/urandom [ chr_file ] Source upsmon Source Path /usr/sbin/upsmon Port <Unknown> Host (removed) Source RPM Packages nut-client-2.7.3-2.fc22.x86_64 nut-2.7.3-2.fc22.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-128.18.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.5-201.fc22.x86_64 #1 SMP Wed Oct 28 20:00:23 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-11-14 16:39:32 CST Last Seen 2015-11-14 16:39:32 CST Local ID 4e3f1220-d320-4885-a56c-831ddf56ef67 Raw Audit Messages type=AVC msg=audit(1447540772.979:1494): avc: denied { open } for pid=18587 comm="upsmon" path="/dev/urandom" dev="devtmpfs" ino=1033 scontext=system_u:system_r:nut_upsmon_t:s0 tcontext=system_u:object_r:urandom_device_t:s0 tclass=chr_file permissive=0 type=SYSCALL msg=audit(1447540772.979:1494): arch=x86_64 syscall=open success=no exit=EACCES a0=7f22258de131 a1=900 a2=489b a3=120 items=0 ppid=18586 pid=18587 auid=4294967295 uid=57 gid=57 euid=57 suid=57 fsuid=57 egid=57 sgid=57 fsgid=57 tty=(none) ses=4294967295 comm=upsmon exe=/usr/sbin/upsmon subj=system_u:system_r:nut_upsmon_t:s0 key=(null) Hash: upsmon,nut_upsmon_t,urandom_device_t,chr_file,open Version-Release number of selected component: selinux-policy-3.13.1-128.18.fc22.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.5-201.fc22.x86_64 type: libreport Potential duplicate: bug 1116597
