Hi, >ioc13lab> iocClockSyncWithNTPserver: sntpcTimeGet S_sntpcLib_TIMEOUT That error message problem was EPICS IOC dose not connected NTP Servers. First you must checking your NTP servers alive and it?s better synchronization with GPS time. Second route add, time zone, environment variable to boot script files. My startup script "st.cmd" files examples. #141.223.182.106 ? NTP server #141.223.48.99 ? EPICS IOC subnet routeAdd("141.223.182.106", "141.223.48.99") putenv("TIMEZONE=KST::-540:000000:000000") #KOREA zone putenv("EPICS_TS_MIN_WEST=-540") putenv("EPICS_TS_NTP_INET=141.223.182.106") #PLS NTP server IP # This comment helped Timo, who SLS Control people. # # Time stamp support software configuration: # # The parameters: # 1. master_indicator: 1=master timing IOC, 0=slave, default is slave. # 2. sync_rate_seconds: The clock sync rate in seconds, default 10 seconds. # 3. clock_rate_hz: The frequency in hertz of the clock. # Default 1000Hz for the event system # and IOC's internal clock rate when soft timing is used. # 4. master_port: The UDP port for a master to receive ts requests, # default 18323. # 5. slave_port: The UDP port for a slave to receive time stamps # from a master. # 6. time_out: UDP information request time out in milliseconds, default 250ms. # 7.

FTP and NFS are working fine, so the IOC boots OK. However, it then prints the message: > ioc13lab> iocClockSyncWithNTPserver: sntpcTimeGet S_sntpcLib_TIMEOUT > > which means that it was not able to get the time from the boot host.

By default neither "ntpd" nor "timed" seem to be running (as judged from "ps -ax"). Manually starting "ntpd" and/or "timed" did not help, the IOC still does not get the time when it boots. > > Does anyone have an idea on what time server I should be running for vxWorks to be able to get the time, and how to correctly start that on Darwin? > > Thanks, > Mark Rivers > |
