I fixed the port problem by setting the port type to ssh_port_t, so I suppose you can ignore that issue. |
Description of problem: SELinux is preventing /usr/sbin/sshd from 'name_bind' accesses on the tcp_socket . ***** Plugin bind_ports (92.2 confidence) suggests ************************* If you want to allow /usr/sbin/sshd to bind to network port 9922 Then you need to modify the port type. Do # semanage port -a -t PORT_TYPE -p tcp 9922 where PORT_TYPE is one of the following: ssh_port_t, vnc_port_t, xserver_port_t. ***** Plugin catchall_boolean (7.83 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 'None' man page for more details. Do setsebool -P nis_enabled 1 ***** Plugin catchall (1.41 confidence) suggests *************************** If you believe that sshd 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 sshd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:sshd_t:s0-s0:c0.c1023 Target Context system_u:object_r:unreserved_port_t:s0 Target Objects [ tcp_socket ] Source sshd Source Path /usr/sbin/sshd Port 9922 Host (removed) Source RPM Packages openssh-server-6.2p2-5.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-73.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.10.10-200.fc19.x86_64 #1 SMP Thu Aug 29 19:05:45 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-09-04 21:03:28 PDT Last Seen 2013-09-04 21:03:28 PDT Local ID cf4b5033-05c9-493f-96e7-007adf514f8f Raw Audit Messages type=AVC msg=audit(1378353808.140:1012): avc: denied { name_bind } for pid=23928 comm="sshd" src=9922 scontext=system_u:system_r:sshd_t:s0-s0:c0.c1023 tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket type=SYSCALL msg=audit(1378353808.140:1012): arch=x86_64 syscall=bind success=no exit=EACCES a0=3 a1=7f2ccfd9c210 a2=1c a3=7fff9822ffa4 items=0 ppid=1 pid=23928 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=sshd exe=/usr/sbin/sshd subj=system_u:system_r:sshd_t:s0-s0:c0.c1023 key=(null) Hash: sshd,sshd_t,unreserved_port_t,tcp_socket,name_bind Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.10.10-200.fc19.x86_64 type: libreport Potential duplicate: bug 890781
