2008-06-10For IPv6 addresses, return the first 32 bits of the MD5 hash of theChristian Weisgerber
address as ref ID (RFC4330). ok henning@
2008-06-10According to the latest SNTPv4 spec in RFC4330, secondary serversChristian Weisgerber
return the address of the synchronization source as reference identification. Remove the obsolete special casing specified in RFC2030. ok henning@
2008-01-28Reconnect a client socket after three consecutive send failures.Marco Pfatschbacher
This allows recovery after an IP address change (e.g. on dialup links). Also move the update of "nextaction" timeout below the deadline check. OK henning@
2007-12-27some fatal() calls that should be fatalx(); ok henning@Kevin Steves
2007-11-22be a bit less aggressive retrying; this keeps the message queueOtto Moerbeek
empty while in the -s period, so the poll timeout actually times out if there are no interfaces available. ok henning@
2007-05-01if resolving a name fails, be more aggressive retrying, but with care:Otto Moerbeek
do not have more than one dns request outstanding per peer. resolves slow recovery when resolving fails initially, without clogging the pipe with lots of dns requests; tested by Jason George; ok deraadt@
2007-04-30aggressive spelling fix, spotted by jbgTheo de Raadt
2006-10-27use clock_gettime(CLOCK_MONOTONIC, ..) to get a monotonically increasingHenning Brauer
time, and make ntpd use that to send the next uery to an ntp peer and the like. this has the advantage that changes to the clock do not interfere with the intervals. for example, when we start on machines without an RTC and the initial settime (-s) kicks in, intervals were strange. idea from amandal@entrisphere.com, this implementation by me tested ckuethe, phessler, mbalmer, ok mbalmer

2006-06-07Compensate old offsets with the amount of adjustment done, avoidingOtto Moerbeek
overcompensating. From DragonFly, uses recent adjtime(2) changes, so you'll need a recent kernel. ok henning@

2004-09-18add a new -s option, that tells ntpd to set the time using settimeofday()Henning Brauer
once at startup. ntpd delays daemonizing until it has done the intial time setting (or ran into the timeout) in this mode to make sure stuff started later in rc is not subject to time jumps. this eleminates the need to run rdate -n beforehands. with some input from & ok ryan and bob, march music from mickey
