Instructions

Nota: Se si disabilita un servizio come NFS, Swift, si consiglia di eseguire l'aggiornamento alla versione 3.4.x o successiva e di seguire le 000022052 della KB: (solo i clienti Dell registrati possono accedere al contenuto del link all'articolo, oltre il Dell.com/support)

Questo articolo della Knowledge Base mostra come disabilitare le porte degli oggetti non utilizzate o disabilitate per motivi di sicurezza. Per ulteriori informazioni, consultare la Guida alla sicurezza di ECS più recente disponibile sul sito web di supporto Dell.

  1. Per ottenere le configurazioni correnti, eseguire una query con una richiesta GET:    
# curl -sk -X GET -H "$TOKEN" -H "ACCEPT:application/xml" -H "Content-Type: application/xml" https://<management_IP>:4443/service/
 
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<services>
  <service>
    <name>atmos</name>
    <settings>http</settings>
    <settings>https</settings>
  </service>
  <service>
    <name>cas</name>
    <settings>enabled</settings>
  </service>
  <service>
    <name>hdfs</name>
    <settings>enabled</settings>
  </service>
  <service>
    <name>nfs</name>
    <settings>enabled</settings>
  </service>
  <service>
    <name>s3</name>
    <settings>http</settings>
    <settings>https</settings>
  </service>
  <service>
    <name>swift</name>
    <settings>http</settings>
    <settings>https</settings>
  </service>
</services>
  1. Creare un file utilizzando VI e modificarlo per rimuovere le impostazioni non necessarie. Inoltre, questa è la posizione in cui un servizio viene disabilitato sostituendo enabled con disabled.
Esempio di disabilitazione di NFS e rimozione di HTTP da tutti i servizi:    
# cat /home/admin/service.conf
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<services>
  <service>
    <name>atmos</name>
    <settings>https</settings>
  </service>
  <service>
    <name>cas</name>
    <settings>enabled</settings>
  </service>
  <service>
    <name>hdfs</name>
    <settings>enabled</settings>
  </service>
  <service>
    <name>nfs</name>
    <settings>disabled</settings>
  </service>
  <service>
    <name>s3</name>
    <settings>https</settings>
  </service>
  <service>
    <name>swift</name>
    <settings>https</settings>
  </service>
</services>
  1. Carica le modifiche per applicarle.
Esempio:      
# curl -kv -X PUT -H "$TOKEN" -H "Content-Type: application/xml" -H "ACCEPT:application/xml" -d @service.conf https://<managment_IP>:4443/service

admin@ecssh121:~> curl -kv -X PUT -H "$TOKEN" -H "Content-Type: application/xml" -H "ACCEPT:application/xml" -d @service.conf https://xx.xx.xx.xx1:4443/service*   Trying 1xxxx

Additional Information

Per creare un TOKEN per l'utente di gestione:     
# TOKEN=$(curl -i -k https://Mangement-IP:4443/login -u <mangement user>:<PassWord> | grep X-SDS-AUTH-TOKEN);echo $TOKEN
Se questa operazione viene eseguita direttamente su ECS, utilizzare svc_rest_cmd: 
# svc_rest_cmd get /service/
Per applicare le modifiche con svc_rest_cmd, definire l'utente di gestione: 
# svc_rest_cmd PUT -u root -p ChangeMe -xml -file /home/admin/service.conf service/
Non è necessario eseguire tutti i servizi contemporaneamente; possono essere svolti servizi individuali (service/atmos oppure service/nfs).
