I started ntp in my linux box like this: ntpd -D99 I want to syncronize with a GPS only connected to the serial port My ntp.conf file is: fudge 127.127.20.0 nopeer calibrate monitor ntp stats server 127.127.20.0 mode 1 version 4 prefer driftfile /etc/ntp.drift logfile /var/log/ntp logconfig =all
Output from ntpd is shown below. In the standard output i'm getting the error "addto_syslog: select(): nfound=-1, error: Interrupted system call". What doest it mean. Should I worry about this error. For a c++ programmer like me, an error on select(), mean a server disconnect from a tcp connection !!! Is that true ? ------------------------------------------------------------------------------------------------------------------------------------- getrecvbufs returning 1 buffers refclock_gtlin: fd 9 time 3393658142.241836 getrecvbufs called, no action here addto_syslog: select(): nfound=-1, error: Interrupted system call getrecvbufs called, no action here getrecvbufs called, no action here addto_syslog: input_handler: Processed a gob of fd's in 0.021000 msec getrecvbufs returning 2 buffers refclock_gtlin: fd 9 time 3393658143.001926 timecode 72 $GPRMC, 104903,A,4517.065 5,N,07316.2283,W,000.0,137.7,170707,015.5,W,D*1D nmea: gpsread 72 $GPRMC,104903,A,4517.0655,N,07316.2283,W, 000.0,137.7,170707,015 .5,W,D*1D nmea: timecode 72 $GPRMC,104903,A,4517.0655,N,07316.2283,W, 000.0,137.7,170707,01 5.5,W,D*1D refclock_gtlin: fd 9 time 3393658143.001926 getrecvbufs called, no action here addto_syslog: input_handler: Processed a gob of fd's in 0.020000 msec getrecvbufs returning 2 buffers refclock_gtlin: fd 9 time 3393658143.141940 timecode 67 $GPGGA, 104903,4517.0655, N,07316.2283,W,2,05,5.5,45.9,M,-32.4,M,,*40 nmea: gpsread 67 $GPGGA,104903,4517.0655,N,07316.2283,W, 2,05,5.5,45.9,M,-32.4,M, ,*40 refclock_gtlin: fd 9 time 3393658143.141940 getrecvbufs called, no action here addto_syslog: input_handler: Processed a gob of fd's in 0.018000 msec getrecvbufs returning 2 buffers refclock_gtlin: fd 9 time 3393658143.241950 timecode 45 $GPGLL, 4517.0655,N,07316 .2283,W,104903,A,D*56 nmea: gpsread 45 $GPGLL,4517.0655,N,07316.2283,W,104903,A,D*56 refclock_gtlin: fd 9 time 3393658143.241950 getrecvbufs called, no action here addto_syslog: select(): nfound=-1, error: Interrupted system call _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
