Zennio NTP Clock Master Clock Modyuli
INTSHAYELELO
Iintlobo ngeentlobo zezixhobo zeZennio zibandakanya imodyuli yeClock yeNTP, ngokukodwa, iintsapho ALLinBOX kunye neKIPI. Le modyuli ivumela isixhobo ukuba siqwalaselwe njengewotshi enkulu yokuhlohla, ukuthumela umhla kunye nolwazi lwexesha oludityaniswe nolwazi olufunyenwe kwiseva ye-NTP. La macandelo alandelayo achaza iiparamitha eziyimfuneko ukuqwalasela iiseva kunye nohlengahlengiso olunokuthi lwenziwe kumhla kunye nexesha elifunyenweyo. Ukongeza, ukhetho oluhlukeneyo lomhla kunye nexesha lokuthumela lunokusetwa.
UQINISEKISO NGOKUBANZI
Kuyakwenzeka ukumisela uluhlu ukuya kuthi ga kwiiseva ezimbini ze-NTP zokungqamanisa ulwazi lomhla kunye nexesha. Ngenxa yale njongo, isixhobo siya kuthumela izicelo kumncedisi wokuqala kuluhlu, ukuba kukho impazamo efunyenweyo, eyesibini iqwalaselwe iya kusetyenziswa. Ukuba nayiphi na kuzo ingumncedisi osebenzayo, akukho mhla okanye iyure eya kufunyanwa kwaye ke akukho nto iya kuthunyelwa ebhasini. Ixesha lendawo lesixhobo liya kulawulwa ngummandla wexesha omiselweyo, ukwazi ukukhetha indawo yexesha lesiqhelo kunye ne-offset kwimizuzu ngokubhekiselele kwixesha le-UTC lomncedisi. Ukongeza, kwaye njengoko amanye amazwe ecinga ngotshintsho lwexesha lasehlotyeni njengendlela yokonga umbane, oku kunokwenzeka kunokwenziwa kusebenze kwaye kuqwalaselwe.
ETS PARAMETERISATION
Emva kokwenza i-Synchronize Clock Master nge-NTP ukusuka kwi-"General" ithebhu yemveliso ukuyiqwalasela, ithebhu entsha yongezwa kumthi wasekhohlo, "NTP", kunye nee-sub-tabs ezimbini, "Ubumbeko Jikelele" kunye "noThunyelwa". Kwakhona kwithebhu ethi "Ngokubanzi" yesixhobo, iiparamitha zoqwalaselo zeeseva ze-DNS ziyaboniswa. Kuya kufuneka ukuba nemilinganiselo efanelekileyo yokusebenza kwewotshi ye-NTP, ngakumbi ukuba umncedisi we-NTP uqwalaselwe njenge-domain, oko kukuthi isicatshulwa, ekubeni iseva ye-DNS iya kuboniswana kwidilesi ye-IP yale mncedisi we-NTP.
Uqwalaselo lweeSeva ze-DNS:
imihlaba yokubhaliweyo kwamanani ukungena kwidilesi ye-IP yeeseva ezimbini ze-DNS: Idilesi ye-IP ye-DNS Server 1 kunye ne-2 [198.162.1.1, 198.162.1.2].
Phawula:
Uninzi lweerotha zinomsebenzi womncedisi we-DNS, ngoko ke i-IP ye-router, eyaziwa ngokuba yisango, inokugcinwa njengeseva. Olunye ukhetho lunokuba ngumncedisi we DNS wangaphandle, umzekeloample "8.8.8.8", inikezwe nguGoogle.
I-subtab ethi "Uqwalaselo Jikelele" ibonelela ngeeparamitha zoqwalaselo lweeseva ze-NTP kunye nezicwangciso zexesha. 
Ubumbeko lwe-NTP:
iindawo zokubhaliweyo ezinobude obuninzi bamagama angama-24 ukungena kwi-domain/IP yeeseva ezimbini ze-NTP.
I-Domain/IP ye-NTP Server 1 kunye ne-2 [0.pool.ntp.org, 1.pool.ntp.org].
Phawula:
I-IP ingaqwalaselwa kulo mmandla, ukuze isicelo se-NTP senziwe ngokuthe ngqo kumncedisi, ngaphandle kokubuza umncedisi we DNS.
Ixesha lendawo
[(UTC+0000) Dublin, Edinburgh, Lisbon, London, Reykjavik / ... / Isiko]: iparameter ukukhetha izowuni yexesha ngokwejografi yesixhobo. Ukuba "isiko" sikhethiwe, iparameter entsha iya kuboniswa:
I-Offset [-720…0…840] [x 1min]: umahluko wexesha ngokubhekiselele kwixesha le-UTC lomncedisi.
Ixesha Lokugcinwa Kwemini (DST) [ivaliwe/ivuliwe]:
yenza ukuba ukusebenza kusebenze ixesha lasehlotyeni okanye lasebusika. Ukuba le parameter yenziwe, ixesha liya kuhlaziywa ngokuzenzekelayo xa ixesha lasehlotyeni liqala kwaye liphela. Ukongeza, ezi parameters zilandelayo ziya kuboniswa:
Utshintsho lweXesha lasehlotyeni [I-Europa / i-USA kunye neCanada / iSiko]: ipharamitha ukukhetha umgaqo wokutshintsha ixesha. Ukongeza kwezona ziphambili (iYurophu okanye iMelika), umgaqo wokutshintsha ixesha olungiselelweyo unokuchazwa: 
Thumela iXesha ngoTshintsho [ikhubazekileyo/inikwe amandla]: yenza ukuba kuthunyelwe izinto zomhla nexesha (“[NTP] Umhla”, “[NTP] Ixesha leMini”, “[NTP] Umhla kunye nexesha”) ixesha ngalinye utshintsho ukuya ehlotyeni okanye ixesha lasebusika liyenzeka.
IZITHUNYWA
Enye ithebhu iya kufumaneka ukulungiselela iinketho zokuthumela ukuthumela umhla kunye nexesha ulwazi emva kweziganeko ezithile: emva kokuqalisa ngokutsha kwesixhobo, kanye xa uxhulumaniso kuthungelwano lubuyiselwe, emva kwexesha kunye / okanye xa ixesha elimisiweyo. sele kufikelelwe kuyo. Kubalulekile ukubonisa ukuba ezi zinto ziya kuthunyelwa kuphela ukuba uxhulumaniso kunye nomncedisi we-NTP oqwalaselweyo luphunyeziwe, ngaphandle koko, izinto aziyi kuthunyelwa kwaye, ukuba zifundwa, ziya kubuyisela amaxabiso kwi-zero. Ngakolunye uhlangothi, ukuba emva kokudibanisa, uxhulumaniso kunye nomncedisi we-NTP lulahlekile, isixhobo siya kugcina ukuthumela kude kuqaliswe kwakhona.
ETS PARAMETERISATION
Emva kokwenza i-Synchronize Clock Master nge-NTP ukusuka kwi-"General" ithebhu, ithebhu entsha yongezwa kumthi wasekhohlo, "NTP", kunye nee-subtabs ezimbini, "Ubumbeko Jikelele" kunye "noThumela". Kwi-subtab ethi "Ukuthunyelwa", iindidi ezahlukeneyo zokuthumela zinokuvulelwa izinto zomhla kunye nexesha "[NTP] Umhla", "[NTP] Ixesha leMini" kunye "ne[NTP] Umhla kunye nexesha". 
Thumela Umhla/Ixesha emva koqhagamshelo lokuqala [lukhubaziwe/ luvuliwe]:
ukuba yenziwe, izinto zomhla kunye nexesha ziya kuthunyelwa nje ukuba ungqamaniso nomncedisi we-NTP lugqityiwe emva kokuphinda kuqaliswe isixhobo. Ukongeza, ukulibaziseka [0…255] [x 1s] kunokusetwa ekuthumeleni izinto emva kokuba unxibelelwano luphelile.
Thumela Umhla/Ixesha emva koqhagamshelo lomnatha [oluvaliweyo/lwenziwe]:
ukuba kuye kwakho uqhagamshelo kwiseva ye-NTP, izinto zomhla kunye nexesha zingathunyelwa emva kokuqhagamshelwa kwakhona.
Umhla kunye nexesha Ukuthunyelwa kwamaxesha [kukhubaziwe/kunikwe amandla]:
yenza ukuba izinto zomhla kunye nexesha zithunyelwe ngamaxesha athile, kwaye ixesha phakathi kokuthumela kufuneka liqwalaselwe (Ixabiso [[0…10…255][s/min] / [0…24][h]]).
Ukuthumela Ixesha elimiselweyo [kuvaliwe/kunikwe amandla]:
ukuba yenziwe, umhla kunye nexesha ziya kuthunyelwa yonke imihla ngexesha elithile [00:00:00…23:59:59][hh:mm:ss].
Ukongeza kwiparameterised ukuthumela, ukufika kwexabiso '1' ngento “[NTP] Ukuthumela isicelo” kuya kuxhokonxa ukuthunyelwa komhla kunye nexesha.
