Description of problem: SELinux is preventing /usr/lib64/erlang/erts-5.10.4/bin/beam.smp from name_bind access on the tcp_socket resulting in ejabberd.service failed to start. Version-Release number of selected component (if applicable): ejabberd-2.1.13-7.fc20.x86_64 selinux-policy-3.12.1-119.fc20.noarch How reproducible: Always. Steps to Reproduce: 1. yum install ejabberd 2. systemctl start ejabberd.service Actual results: SELinux is preventing /usr/lib64/erlang/erts-5.10.4/bin/beam.smp from name_bind access on the tcp_socket . ***** Plugin bind_ports (92.2 confidence) suggests ************************ If you want to allow /usr/lib64/erlang/erts-5.10.4/bin/beam.smp to bind to network port 5280 Then you need to modify the port type. Do # semanage port -a -t PORT_TYPE -p tcp 5280 where PORT_TYPE is one of the following: amqp_port_t, couchdb_port_t, jabber_client_port_t, jabber_interserver_port_t. ***** Plugin catchall_boolean (7.83 confidence) suggests ****************** If you want to allow nis to enabled Then you must tell SELinux about this by enabling the 'nis_enabled' boolean. You can read 'None' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (1.41 confidence) suggests ************************** If you believe that beam.smp should be allowed name_bind access on the 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 beam.smp /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:rabbitmq_beam_t:s0 Target Context system_u:object_r:unreserved_port_t:s0 Target Objects [ tcp_socket ] Source beam.smp Source Path /usr/lib64/erlang/erts-5.10.4/bin/beam.smp Port 5280 Host srv9.kola.fad.ru Source RPM Packages erlang-erts-R16B-03.1.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-119.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name srv9.kola.fad.ru Platform Linux srv9.kola.fad.ru 3.12.7-300.fc20.x86_64 #1 SMP Fri Jan 10 15:35:31 UTC 2014 x86_64 x86_64 Alert Count 2 First Seen 2014-01-31 03:45:45 MSK Last Seen 2014-01-31 03:57:01 MSK Local ID 2224fce7-a18c-4fea-b21a-c51da09807d4 Raw Audit Messages type=AVC msg=audit(1391126221.107:17780): avc: denied { name_bind } for pid=11054 comm="beam.smp" src=5280 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket type=SYSCALL msg=audit(1391126221.107:17780): arch=x86_64 syscall=bind success=no exit=EACCES a0=15 a1=7f2568eaf980 a2=10 a3=1 items=0 ppid=1 pid=11054 auid=4294967295 uid=994 gid=993 euid=994 suid=994 fsuid=994 egid=993 sgid=993 fsgid=993 ses=4294967295 tty=(none) comm=beam.smp exe=/usr/lib64/erlang/erts-5.10.4/bin/beam.smp subj=system_u:system_r:rabbitmq_beam_t:s0 key=(null) Hash: beam.smp,rabbitmq_beam_t,unreserved_port_t,tcp_socket,name_bind Additional info: Port 5280/tcp - ejabberd web interface (captcha, http_bind, http_poll, register, web_admin) by default. Supposed to resolve with > semanage port -a -t PORT_TYPE -p tcp 5280 But can't decide what port type should I use. Setroubleshoot proposed port types don't match the purpose well.
