E’ possibile regolare l’orologio del proprio PC attraverso internet. E’ sufficiente installare il pacchetto rdate. Una volta connessi ad internet date il seguente comando:<\/p>\n

\n

rdate -s time.ien.it && hwclock –systohc<\/p>\n<\/blockquote>\n

E’ possibile anche farlo eseguire automaticamente alla connessione, \u00e8 sufficiente creare uno script Bash:<\/p>\n

\n

#!\/bin\/sh
\n\/usr\/sbin\/rdate -s time.ien.it && hwclock –systohc<\/p>\n<\/blockquote>\n

Salvatelo con un nome qualsiasi ad esempio ora.sh, rendetelo eseguibile :<\/p>\n

\n

chmod +x ora.sh<\/p>\n<\/blockquote>\n

E copiatelo nella directory \/etc\/ppp\/ip-ip.d\/<\/p>\n

Da notare che molte distribuzioni allo shutdown effettuano gi\u00e1 la sincronizzazione del hwclock, quindi “&& hwclock –systohc” potrebbe essere superfluo. Se la macchina \u00e8 un server inoltre, \u00e8 opportuno eseguire giornalmente via cron la sincronizzazione, in quanto il reboot avviene o dovrebbe avvenire normalmente di rado. Se si installa il pacchetto anacron o un demon cron sufficientemente recente, che gestisce la stringa @reboot, l’uso di un cron file adatto si potrebbe considerare in alternativa soprattutto in una configurazione di connessione a internet via router.<\/p>\n","protected":false},"excerpt":{"rendered":"
