&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Se in fase di apertura di una pagina Internet con browser lo stesso segnala un errore legato al server proxy Squid che non riesce a trovare i DNS, il problema si risolve modificando la configurazione dello Squid. Inoltre, un altro segnale di errore è dato dal fatto che, tendando di restartare il demone Squid con il comando&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
fire:/var/run# /etc/init.d/squid start&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
si ottiene la seguente risposta:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
Starting proxy server: FATAL: Could not determine fully qualified hostname.  Please set &amp;#039;visible_hostname&amp;#039;&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Per modificare la configurazione settando il &amp;#039;visible_hostname&amp;#039; bisogna:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
vi /etc/squid/squid.conf&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
e inserire al posto giusto, cioè&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
...&lt;br /&gt;
#  TAG: visible_hostname&lt;br /&gt;
#       If you want to present a special hostname in error messages, etc,&lt;br /&gt;
#       then define this.  Otherwise, the return value of gethostname()&lt;br /&gt;
#       will be used. If you have multiple caches in a cluster and&lt;br /&gt;
#       get errors about IP-forwarding you must set them to have individual&lt;br /&gt;
#       names with this setting.&lt;br /&gt;
#&lt;br /&gt;
#Default:&lt;br /&gt;
# none&lt;br /&gt;
...&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
la dicitura&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
visible_hostname proxy.mannesmann.priv&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Ovviamente il nome cambierà a seconda della macchina su cui si fa la modifica. Il file /etc/squid/squid.conf diventerà:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
...&lt;br /&gt;
#  TAG: visible_hostname&lt;br /&gt;
#       If you want to present a special hostname in error messages, etc,&lt;br /&gt;
#       then define this.  Otherwise, the return value of gethostname()&lt;br /&gt;
#       will be used. If you have multiple caches in a cluster and&lt;br /&gt;
#       get errors about IP-forwarding you must set them to have individual&lt;br /&gt;
#       names with this setting.&lt;br /&gt;
#&lt;br /&gt;
#Default:&lt;br /&gt;
# none&lt;br /&gt;
visible_hostname proxy.mannesmann.priv&lt;br /&gt;
#  TAG: unique_hostname&lt;br /&gt;
#       If you want to have multiple machines with the same&lt;br /&gt;
#       &amp;#039;visible_hostname&amp;#039; then you must give each machine a different&lt;br /&gt;
#       &amp;#039;unique_hostname&amp;#039; so that forwarding loops can be detected.&lt;br /&gt;
#&lt;br /&gt;
#Default:&lt;br /&gt;
# none&lt;br /&gt;
...&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;/div&gt;</summary>
