Description of problem:
SELinux is preventing rpcbind from 'name_bind' accesses on the udp_socket Port 61971.

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

Sie möchten rpcbind erlauben, mit dem Netzwerk-Port $​​PORT_NUMBER zu verbinden
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p udp 61971
    wobei PORT_TYPE einer der folgenden Werte ist: 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   ******************

Sie folgendes tun möchten: allow nis to enabled
Then sie müssen SELinux darüber benachrichtigen, indem Sie die \tboolesche Variable »nis_enabled« aktivieren.

Do
setsebool -P nis_enabled 1

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

Wenn Sie denken, dass es rpcbind standardmäßig erlaubt sein sollte, name_bind Zugriff auf Port 61971 udp_socket zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'rpcbind' --raw | audit2allow -M my-rpcbind
# semodule -X 300 -i my-rpcbind.pp
