Isingeniso
Umyalo we-Linux host host usetshenziselwa ukuthola ikheli le-IP lesizinda. Kungasetshenziswa futhi ukuthola igama lesizinda lekheli le-IP.
Lo mhlahlandlela uzokubonisa ukuthi ungasebenzisa kanjani ukushintshwa okuvame kakhulu nomyalo wokusingatha.
I-Host Command
Ngokwakho umyalo wokusingatha uzobuyisela uhlu lwazo zonke izinguquko ezingase zisetshenziswe nazo.
Ukuze uthole uhlu lwalolu hlobo olulandelayo efasiteleni lokugcina:
bamba
Imiphumela elandelayo izoboniswa:
- -a - lilingana no -v -t NOMA
- -c - icacisa iklasi yombuzo ye-non-IN yedatha
- -C - uqhathanisa amarekhodi e-SOA kuma-nameservers onegunya
- -d - ilingana no -v
- -l - libala bonke abakwaSibindi esizindeni, besebenzisa i-AXFR
- -i - IP6.INT ukubuyela emuva
- -N - ishintsha inani lamachashazi avunyelwe ngaphambi kokucutshungulwa kwempande
- -r - ukhubaza ukucubungula okuqhubekayo
- -R - icacisa inani lokubukeka kwamaphakethe we-UDP
- -s - impendulo ye-SERVFAIL kufanele imise umbuzo
- -t - icacisa uhlobo lombuzo
- -T - yenza imodi ye-TCP / IP
- -v - kwenza umkhiqizo we-verbose
- -w - icacisa ukulinda kuze kube phakade impendulo
- -W - ucacisa isikhathi esingakanani sokulinda impendulo
- -4 - sebenzisa i-IPv4 imibuzo yokuthutha kuphela
- -6 - sebenzisa i-IPv6 imibuzo yokuthutha kuphela
- -m - setha imemori ukulungisa ifulegi
- -V - ukuphrinta inombolo yenguqulo bese uphuma
Njengemilayezo eminingi ye-Linux kunezinguquko eziningi kodwa eziningi ngeke zidingeke kulokho okudingeka ukwenze.
Ungathola kabanzi mayelana nomyalo wokusingatha ngokufunda ikhasi lezincwadi.
Vele uthayiphe lokhu okulandelayo efasiteleni lokugcina:
umuntu ophethe
Thola ikheli le-IP legama legama
Ukubuyisela ikheli le-IP legama lesizinda mane uthayiphe umyalo olandelayo:
Isibonelo ukuthola igama lesizinda se-linux.about.com thayipha umyalo olandelayo.
londoloza linux.about.com
Imiphumela evela kumyalo wokusingathwa kuyoba kanje:
I-linux.about.com iyinhlangano ye-dynglbcs.about.com.
i-dynglbcs.about.com ikhuluma no-207.241.148.82
Yiqiniso linux.about.com iyisizinda esincane se-about.com. Ukugijima komyalo we-host ngokumelene negama eligcwele le-about.com lesizinda libuyisela ikheli le-IP elihlukile.
i-about.com ikhulume ku-207.241.148.80
Kukhona okunye okukhipha kumyalo wokusingatha ngokumelene ne-about.com njengoba ubonisa ukuthi i-mail isingathwa kanjani.
Ngokwesibonelo:
Imeyili ye-about.com iphathwa nge-ALT4.ASPMX.L.Google.com engu-500
Thola Igama Legama Kusuka Ikheli le-IP
Okuphambene nokubuyisela ikheli le-IP elisuka egameni lesizinda libuyisela igama lesizinda kusuka ekhelini le-IP.
Ungakwenza lokhu ngokuthayipha lokhu okulandelayo efasiteleni lokugcina:
Isibonelo siyazi ukuthi i-207.241.148.80 yikheli le-IP le-About.com. Thayipha lokhu okulandelayo efasiteleni lokugcina:
bamba 207.241.148.80
Imiphumela yile ndlela elandelayo:
82.148.241.207.in-addr.arpa igama lesizinda pointer glbny.about.com.
Umyalo wokusingathwa ngokuzenzakalelayo ubuyisela ulwazi olwanele kodwa ungathola okukhipha okuningiliziwe ngokusebenzisa inkinobho -d noma -v kanje:
host -d linux.about.com
Imiphumela evela kumyalo ongenhla ibonisa isizinda esibhekwe phezulu nanoma yimiphi imiphumela. Ibuye ibuyisele imininingwane ye-SOA yesizinda.
Buyisela imininingwane ye-SOA Ye-Domain
I-SOA imele i-Start Of Authority. Uma ubhalisa igama lesizinda bese ubamba lesi sizinda ngenkampani yokubamba iwebhu inkampani ye-web hosting kumele ilondoloze i- SOA yalesi sizinda. Inikeza indlela yokugcina ithrekhi yamagama wesizinda.
Ungathola imininingwane ye-SOA yesizinda ngokuthayipha umyalo olandelayo:
host -C
i-host
Isibonelo faka lokhu okulandelayo efasiteleni lokugcina:
host -C about.com
Kunemiphumela eminingi ebuyiselwe kodwa yonke inemikhakha efanayo elandelayo:
- Igama legama eliyinhloko
- Ithimba eliphetheyo lesizinda
- I-timestamp eshintsha uma isizinda sibuyekezwa
- Inombolo yamasekhondi ngaphambi kokuba indawo ivuselelwe
- Inani lamasekhondi ngaphambi kokuvuselela okuphumelelayo kufanele kulandelwe
- Umkhawulo ongaphezulu ngamasekhondi ngaphambi kokuba indawo ingabhekwa njengegunya
- Umphumela omubi we-TTL.
Leli khasi lewebhu linikeza ukubuka konke okuhle mayelana ne-SOA.
Isifingqo
Kukhona ngokusobala ezinye ezinye izitshalo ezifana -l ezihlinzeka uhlu futhi -T okuyinto ukusesha usebenzisa TCP / IP esikhundleni UDP.
Uzothola ukuthi amaseva amaningi wewebhu azokwenqaba lezi zinhlobo zombuzo.
Ngokuvamile cishe uzodinga kuphela ukusebenzisa umyalo wokusingatha ukubuyisela ikheli le-IP legama lesizinda noma igama lesizinda lekheli le-IP.
