That's just a warning message. > This command "sntp -d -S -K /dev/null 10.204.134.250" works since > the "-K /dev/null" disables the KoD storage. The -d should not be needed. What is the return status of the sntp command? If it's 0, it thinks it set the time. If it's 1, there was a problem. If there was a problem, sntp should have written something to the syslog. Is there anything interesting there?
