Description of problem: SELinux is preventing /usr/sbin/named from 'name_bind' accesses on the udp_socket port 61000. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow system to run with NIS Then you must tell SELinux about this by enabling the 'nis_enabled' boolean. You can read 'named_selinux' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that named should be allowed name_bind access on the port 61000 udp_socket 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 named /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:named_t:s0 Target Context system_u:object_r:ephemeral_port_t:s0 Target Objects port 61000 [ udp_socket ] Source named Source Path /usr/sbin/named Port 61000 Host (removed) Source RPM Packages bind-9.10.2-5.P4.fc22.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-128.16.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.2.3-200.fc22.x86_64 #1 SMP Thu Oct 8 03:23:55 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-10-19 01:28:44 IST Last Seen 2015-10-19 01:28:44 IST Local ID 085fb678-fb39-4b1c-b8aa-23e2d336cadc Raw Audit Messages type=AVC msg=audit(1445198324.198:1040): avc: denied { name_bind } for pid=1725 comm="named" src=61000 scontext=system_u:system_r:named_t:s0 tcontext=system_u:object_r:ephemeral_port_t:s0 tclass=udp_socket permissive=1 type=SYSCALL msg=audit(1445198324.198:1040): arch=x86_64 syscall=bind success=yes exit=0 a0=212 a1=7f3e29ad3450 a2=10 a3=7f3e29ad3238 items=0 ppid=1 pid=1725 auid=4294967295 uid=25 gid=25 euid=25 suid=25 fsuid=25 egid=25 sgid=25 fsgid=25 tty=(none) ses=4294967295 comm=named exe=/usr/sbin/named subj=system_u:system_r:named_t:s0 key=(null) Hash: named,named_t,ephemeral_port_t,udp_socket,name_bind Version-Release number of selected component: selinux-policy-3.13.1-128.16.fc22.noarch Additional info: reporter: libreport-2.6.2 hashmarkername: setroubleshoot kernel: 4.2.3-200.fc22.x86_64 type: libreport
