Description of problem: Nothing, dhcpd was started on system boot. dhcpd appears to be working fine despite this error. Version-Release number of selected component: selinux-policy-3.13.1-158.9.fc23.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.4.5-300.fc23.x86_64 type: libreport Description of problem: Computer starting, dhcpd server starting from rc.local if I remember correctly. I've never seen any avc denial from that until this policy update. Version-Release number of selected component: selinux-policy-3.13.1-158.12.fc23.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.4.6-301.fc23.x86_64 type: libreport Apparently I have as I was the last commenter? I need to drink less! ;) Still, a policy error for sure. This error also occurs on F22 And in F24 with selinux-policy-targeted-3.13.1-184.fc24.noarch. Perhaps we should change product to dhcpd? I'm in CC list of one particular selinux-policy bug that's 100% reproducible and nothing happens for... I guess I can say _years_ already... Maybe dhcpd maintainer would notice and push a policy update? I see this on Fedora 23 with dhcp-server-4.3.3-9.P1.fc23.x86_64 Is this related to / a dup of Bug 1315802? *** This bug has been marked as a duplicate of bug 1315802 *** |
Description of problem: I was trying to start the dhcpd with the below command when I got this error: systemctl start dhcpd6.service SELinux is preventing /usr/sbin/dhcpd from using the 'fowner' capabilities. ***** Plugin catchall (100. confidence) suggests ************************** If вы считаете, что dhcpd следует разрешить доступ fowner по умолчанию. Then рекомендуется создать отчет об ошибке. Чтобы разрешить доступ, можно создать локальный модуль политики.
