Kubonakala ngathi usuku luyaqina kwaye ngee-28 degrees emthunzini eLas Palmas de Gran Canaria siza kuchaza indlela yokukhupha i-cache ye-DNS kwimeko apho unengxaki xa usombulula i-IP ethile ngokuchasene ne-domain. Sisifundo esincinci esigxile kubasebenzisi abaphambili kuba kuya kufuneka usebenzise i-OS X Terminal.

Into yokuqala ekufuneka uyazi kukuba indlela ekufuneka siyenzile le nyathelo itshintshile ngokufika kwe-OS X Yosemite kwaye, ngokokwazi kwethu, kuya kuqhubeka kulo mthambo kwi-OS X El Capitan eya kukhutshwa ekwindla. Kwiinkqubo zokusebenza ngaphambi kwe-OS X Yosemite inkqubo yenziwe nge-mDNSResponder, kodwa ngoku ithathelwe indawo yi-Discoverutil.

Kwi-OS X Yosemite, ukuqhubeka nokucoca i-cache ye-DNS, kuya kufuneka usebenzise indibaniselwano yemiyalelo emininzi kwi-OS X Terminal. Loo miyalelo iya kugungxula i-MDNS cache (yiMulticast) kunye ne-UDNS cache (i-Unicast). Masiqale ngenkqubo ekufuneka uyenzile ukuze ucofe i-cache ye-DNS:

Sivula iTheminali, esijonge kuyo kwi-Spotlight okanye siye kwi-Launchpad> ENYE ifolda> Itheminali. Nje ukuba iTheminali ivulwe, uya kuqhubeka ubhale le miyalelo ilandelayo:

sudo discoveryutil mdnsflushcache

y

sudo discoveryutil udnsflushcaches

cacisa i-cache-dns

Njengoko ubona, kukho imiyalelo emibini eyahlukeneyo kwaye ngalo lonke ixesha singena omnye siya kucelwa igama eligqithisiweyo lomlawuli kuba beqala ngesudo. Ngoku, ukuba ufuna ukwenza inkqubo ngomgca omnye wekhowudi, kuya kufuneka uyibhale ngolu hlobo:

sudo discoveryutil mdnsflushcache;sudo discoveryutil udnsflushcaches;say flushed

Kwinqaku lokugqibela eli nqaku sibonisa ukuba ukuba ngaphambi kokukhupha i-cache ye-DNS ufuna ukubona ulwazi oluninzi Kwi-Multicast njenge-Unicast kufuneka usebenzise le miyalelo ilandelayo:

sudo discoveryutil mdnscachestats

okanye le ye-Unicast:

sudo discoveryutil udnscachestats

Ukuba ufuna ukwenza oku kwezinye iinkqubo ze-OS X:

I-OS X Mavericks (10.9)

1
dscacheutil -flushcache; sudo killall -HUP mDNSResponder

I-OS X Intaba yeNgonyama (10.8)

1
sudo killall -HUP mDNSResponder

I-OS X Ngonyama (10.7)

1
sudo killall -HUP mDNSResponder

I-OS X Snow Leopard (10.6)

1
sudo dscacheutil -flushcache

OS X Ingwe (10.5)

1
sudo dscacheutil -flushcache

I-OS X Tiger (10.4)

1
lookupd -flushcache
