NTPd státuszkódok

Emlékeztetőnek.

https://docs.opnsense.org/manual/ntpd.html

Nem a legprofibb, de használható részletességű listája az NTP sync során kiköpött paramétereknek

Status

Human readable status of the upstream

Server

Upstream source

Ref ID

Source IP address or kiss code:
 

ACST manycast server
AUTH authentication error
AUTO Autokey sequence error
BCST broadcast server
CRYPT Autokey protocol error
DENY access denied by server
INIT association initialized
MCST multicast server
RATE rate exceeded
TIME association timeout
STEP step time change

 

Stratum

NTP uses a hierarchical, semi-layered system of time sources (wikipedia) This field shows the stratum of the upstream source (lower usually means closer to the actual time source)

Type

Type of time source, one of:

  • u: unicast or manycast client

  • b: broadcast or multicast client

  • p: pool source

  • l: local (reference clock)

  • s: symmetric (peer)

  • A: manycast server

  • B: broadcast server

  • M: multicast server

When

time in seconds, minutes, hours, or days since the last packet was received, or ‘-‘ if a packet has never been received

Poll

poll interval in seconds

Reach

reach shift register (octal), when set to 377 all 8 bits are set and thus no responses have been lost. Convert to bits to inspect which tries failed. (e.g. 257 –> 10101111 means the last four responses where received and two where lost within the last 8 tries)

Delay

roundtrip delay in milliseconds

Offset

offset time in milliseconds of the server relative to this host

Jitter

indicates the difference, in milliseconds, between two samples
