Kubukeka sengathi usuku luyaqina futhi ngama-degree angama-28 emthunzini eLas Palmas de Gran Canaria sizokuchazela ukuthi ungayikhipha kanjani inqolobane ye-DNS uma kwenzeka unezinkinga lapho uxazulula i-IP ethile ngokumelene nesizinda. Lesi isifundo esincane esigxile kubasebenzisi abaphambili ngoba kufanele usebenzise i-OS X Terminal.

Into yokuqala okufanele uyazi ukuthi indlela obekumele senze ngayo lesi senzo kushintshile ngokufika kwe-OS X Yosemite nokuthi, ngokwazi kwethu, kuzoqhubeka kule vein ku-OS X El Capitan ezokhishwa ngokuwa. Kuzinhlelo zokusebenza ngaphambi kwe-OS X Yosemite, inqubo yenziwe nge-mDNSResponder, kepha manje ithathelwe indawo yi-Discoverutil.

Ku-OS X Yosemite ukuqhubeka nokuhlanza isilondolozi se-DNS kufanele usebenzise inhlanganisela yemiyalo eminingi ku-OS X Terminal. Le miyalo izokhipha isilondolozi se-MDNS (yiMulticast) kanye nesilondolozi se-UDNS (i-Unicast). Ake siqale ngenqubo okufanele uyenze ukuze ukwazi ukukhipha isilondolozi se-DNS:

Sivula iTheminali, esiyibheka ku-Spotlight noma siye ku-Launchpad> OTHERS ifolda> Itheminali. Lapho iTheminali isivulekile, uzoqhubeka ubhale imiyalo elandelayo:

sudo discoveryutil mdnsflushcache

y

sudo discoveryutil udnsflushcaches

i-clear-cache-dns

Njengoba ukwazi ukubona, kunemiyalo emibili ehlukile futhi isikhathi ngasinye lapho sifaka owodwa sizocelwa iphasiwedi yomlawuli njengoba iqala ngeSudo. Manje, uma ufuna ukwenza inqubo ngomugqa owodwa wekhodi, kufanele uyibhale kanjena:

sudo discoveryutil mdnsflushcache;sudo discoveryutil udnsflushcaches;say flushed

Okokugcina i-athikili sikhombisa ukuthi uma ngaphambi kokukhipha isilondolozi se-DNS ufuna ukubona imininingwane yokuthi kuningi kakhulu Ku-Multicast njengakwi-Unicast kufanele usebenzise imiyalo elandelayo:

sudo discoveryutil mdnscachestats

noma lena ye-Unicast:

sudo discoveryutil udnscachestats

Uma ufuna ukwenza lokhu kwezinye izinhlelo ze-OS X:

I-OS X Mavericks (10.9)

1
dscacheutil -flushcache; sudo killall -HUP mDNSResponder

I-OS X Mountain Lion (10.8)

1
sudo killall -HUP mDNSResponder

I-OS X Lion (10.7)

1
sudo killall -HUP mDNSResponder

I-OS X Snow Leopard (10.6)

1
sudo dscacheutil -flushcache

I-OS X Leopard (10.5)

1
sudo dscacheutil -flushcache

I-OS X Tiger (10.4)

1
lookupd -flushcache
