***** Plugin bind_ports (92.2 confidence) suggests *************************
If you want to allow /usr/sbin/unbound to bind to network port 8953
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p tcp 8953
where PORT_TYPE is one of the following: rndc_port_t, dns_port_t.
So execute
semanage port -a -t dns_port_t -p tcp 8953
will allow for now.
Unless this is a default port you have to make the modification. |

Do setsebool -P allow_ypbind 1 ***** Plugin catchall (1.41 confidence) suggests *************************** If you believe that unbound should be allowed name_bind access on the port 8953 tcp_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 unbound /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:system_r:named_t:SystemLow Target Context system_u:object_r:port_t:SystemLow Target Objects port 8953 [ tcp_socket ] Source unbound Source Path /usr/sbin/unbound Port 8953 Host (removed) Source RPM Packages unbound-1.4.12-1.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-44.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.35.12 #4 SMP Tue Apr 5 23:22:00 CEST 2011 x86_64 x86_64 Alert Count 2 First Seen Sun 21 Aug 2011 04:36:45 PM CEST Last Seen Sun 21 Aug 2011 04:38:14 PM CEST Local ID 39c2659c-5817-4b1c-b98e-d1679e07c2ad Raw Audit Messages type=AVC msg=audit(1313937494.530:24468): avc: denied { name_bind } for pid=4531 comm="unbound" src=8953 scontext=unconfined_u:system_r:named_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket type=SYSCALL msg=audit(1313937494.530:24468): arch=x86_64 syscall=bind success=no exit=EACCES a0=7 a1=23ff090 a2=1c a3=7fffa4e96d3c items=0 ppid=4530 pid=4531 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=3 comm=unbound exe=/usr/sbin/unbound subj=unconfined_u:system_r:named_t:s0 key=(null) Hash: unbound,named_t,port_t,tcp_socket,name_bind audit2allow #============= named_t ============== #!!!!
