lo strano è che provando con l'opzione -u funziona,

purtroppo mi serve attivo il daemon ntpd sulla macchina, non so se si può istruire ad usare una porta diversa dalla 123,

adesso sposto le indagini sul firewall...

però in debug sembra ricevere i pacchetti, che strano....

Ciao a tutti,

ho un problema con il servizio NTP su una Debian GNU/Linux 6.0,
mi dice "no server suitable for synchronization found"
eppure lanciandolo col -d sembra trovare il sync giusto,

ho provato con vari server ntp...
