I am trying to run # systemctl start saned.socket And SELinux is taking a shine to it. I have run # ausearch -c 'systemd' --raw | audit2allow -M my-systemd # semodule -X 300 -i my-systemd.pp four times and the same SELinux error keeps appearing: The folks over on https://ask.fedoraproject.org/en/question/115386/need-selinux-and-saned-help/?answer=115387#post-id-115387 suggested I report this to you saned.socket [Unit] Description=saned incoming socket [Socket] ListenStream=6566 Accept=yes MaxConnections=1 [Install] WantedBy=sockets.target saned [Unit] Description=Scanner Service Requires=saned.socket [Service] ExecStart=/usr/sbin/saned User=saned Group=saned StandardInput=socket StandardOutput=syslog StandardError=syslog # Environment=SANE_CONFIG_DIR=/etc/sane.d Environment=SANE_CONFIG_DIR=/etc/sane.d SANE_DEBUG_DLL=255 SANE_DEBUG_BJNP=5 SANE_DEBUG_NET=128 [Install] Also=saned.socket SELinux is preventing systemd from listen access on the tcp_socket port None. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd should be allowed listen access on the port None 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: # ausearch -c 'systemd' --raw | audit2allow -M my-systemd # semodule -X 300 -i my-systemd.pp Additional Information: Source Context system_u:system_r:init_t:s0 Target Context system_u:system_r:unconfined_service_t:s0 Target Objects port None [ tcp_socket ] Source systemd Source Path systemd Port <Unknown> Host rn4.xxx.local Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-283.18.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name rn4.xxx.local Platform Linux rn4.xxx.local 4.14.7-300.fc27.x86_64 #1 SMP Mon Dec 18 16:06:12 UTC 2017 x86_64 x86_64 Alert Count 5 First Seen 2017-12-20 13:35:43 PST Last Seen 2017-12-20 13:35:46 PST Local ID 0e806a1d-c379-4c0e-993b-286c5828ef2b Raw Audit Messages type=AVC msg=audit(1513805746.614:968): avc: denied { listen } for pid=1 comm="systemd" lport=6566 scontext=system_u:system_r:init_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=tcp_socket permissive=0 Hash: systemd,init_t,unconfined_service_t,tcp_socket,listen
