A benefit of the re-written clock code -is that adjtime does not round off its adjustments, so xntp does not have to -compensate for this rounding. On Solaris 2.2 and later we #define -ADJTIME_IS_ACCURATE, and do not look for the tickadj kernel variable. - - If you are running both Solaris 2.1 and 2.2 on your net, you will need to -maintain two sets of xntp binaries. The Config.solaris2.2 file will compile -on Solaris 2.1, but the resulting binaries will not work correctly. - -ADDITIONAL NOTES FOR SOLARIS 2.1 -(by William L. Jones jones@chpc.utexas.edu) - -Since settimeofday under Solaris 2.1 only sets the seconds part of timeval -care must be used in starting xntpd. I suggest the following start -up script: - - tickadj -s -a 1000 - ntpdate -v server1 server2 - sleep 20 - ntpdate -v server1 server2 - sleep 20 - tickadj -a 200 - xntpd - -The first tickadj turns of the time of day clock and sets the tick adjust -value to 1 ms. This will insure that an adjtime value of at most 2 -seconds will complete in 20 seconds. - -The first ntpdate will set the time to within two seconds -using settimeofday or it will adjust time using adjtime. - -The first sleep insures the adjtime has completed for the first ntpdate. - -The second ntpdate will use adjtime to set the time of day since the -clock should be within 2 seconds of the correct time. - -The second tickadj set the tick adjust system value to 5 us. - -The second sleeps insure that adjtime will complete before starting -the next xntpd. - -I tried running with a tickadj of 5 us with out much success. -200 us seems to work well. - - -ADDITIONAL NOTES FOR SOLARIS 2.2 AND LATER: - You still need to turn off dosynctodr for XNTP to be able to keep accurate -time. You can either do this in the /etc/system file (consulted at boot to set -various kernel variables) by putting in the following line: -set dosynctodr=0 -or you can use the tickadj program to force the variable to 0 in the running -kernel. Fiddling with a running kernel is almost never a good idea, I'd -recommend using /etc/system. - I would recommend starting xntp from the following script, placed in -/etc/rc2.d and named S99xntpd - -#!/bin/sh - -if [ $1 = "start" ]; then - if [ -x /usr/local/bin/xntpd ]; then - echo "Starting NTP daemon, takes about 1 minute...
