Bug 2418007

Description of problem:
SELinux is preventing /usr/bin/rpcbind from 'name_bind' accesses on the udp_socket porte 63715.

*****  Plugin bind_ports (92.2 confidence) suggests   ************************

Se si desidera permettere che /usr/bin/rpcbind si associ alla porta di rete 63715
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p udp 63715
    dove PORT_TYPE è uno dei seguenti: agentx_port_t, apertus_ldp_port_t, comsat_port_t, dhcpc_port_t, dhcpd_port_t, dns_port_t, efs_port_t, flash_port_t, ftp_port_t, gdomap_port_t, hi_reserved_port_t, inetd_child_port_t, ipmi_port_t, ipp_port_t, kerberos_admin_port_t, kerberos_port_t, kprop_port_t, ktalkd_port_t, ldap_port_t, pki_ca_port_t, pop_port_t, portmap_port_t, printer_port_t, rlogin_port_t, rlogind_port_t, rndc_port_t, router_port_t, rsh_port_t, rsync_port_t, rtsp_port_t, rwho_port_t, smtp_port_t, spamd_port_t, swat_port_t, syslogd_port_t, uucpd_port_t.

*****  Plugin catchall_boolean (7.83 confidence) suggests   ******************

Se si desidera abilitare la seguente funzione: allow nis to enabled
Then è necessario informare SELinux abilitando il booleano 'nis_enabled' .

Do
setsebool -P nis_enabled 1

*****  Plugin catchall (1.41 confidence) suggests   **************************

Se si ritiene che a rpcbind debba essere consentito l'accesso name_bind su udp_socket porte 63715 per impostazione predefinita.
Then si dovrebbe segnalare il problema come bug.
È possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per ora eseguendo:
# ausearch -c 'rpcbind' --raw | audit2allow -M my-$MODULE_NOME
# semodule -X 300 -i mio-rpcbind.pp
