Hauv kev sib piv rau kev siv lub tshuab hluav taws xob hauv Windows, hauv Linux / Unix npuas, ua haujlwm "hauv lub network" yeej ib txwm ua haujlwm, uas piav txog cov kev lag luam uas muaj zog ntawm Unix thiab Linux operating systems . Linux txhawb kev sib txuas ceev thiab ruaj khov mus rau lwm cov computers thiab khiav graphical user interfaces thoob lub network.
Thawj cov lus txib rau kev ua cov haujlwm hauv lub network yog xhost- cov kev pabcuam tswj xyuas cov kev pabcuam rau X. Lub xhost qhov kev zov me nyuam yog siv los ntxiv thiab rho tawm tus tswv tsev (computer) npe los yog cov neeg siv npe rau daim ntawv teev cov cav tov thiab cov neeg siv uas raug tso cai rau kev txuas mus rau X neeg rau zaub mov. Lub moj khaum no muab ib txoj kev tiv thaiv kev tswj hwm tus kheej thiab kev ruaj ntseg.
Siv Scenario
Cia peb hu lub computer koj zaum ntawm "localhost" thiab lub computer koj xav txuas rau "cov chaw taws teeb ." Koj siv thawj xhost qhia kom meej tias lub computer (s) twg koj xav muab kev tso cai rau xa mus rau (X-neeg rau zaub mov ntawm) lub localhost. Tom qab ntawd koj txuas rau cov chaw taws teeb nrug siv telnet. Tom ntej no, koj hloov cov DISPLAY kuj sib txawv thiab ntawm cov chaw taws teeb nrug. Koj xav teem caij sib txawv ntawm tus neeg saib xyuas hauv zos. Tam sim no thaum koj pib ib qho kev pab cuam nyob rau hauv cov chaw taws teeb sab nraud, nws cov GUI yuav tshwm rau cov chaw tswj hauv zos (tsis nyob rau hauv cov chaw taws teeb).
Piv txwv siv Case
Hais qhov IP chaw nyob ntawm tus tswv tsev hauv zos yog 128.100.2.16 thiab IP chaw nyob ntawm cov chaw taws teeb nrug yog 17.200.10.5. Nyob ntawm lub network koj nyob, koj kuj tseem tuaj yeem siv lub npe ntawm cov koos pis taj npe (sau cov npe) es tsis txhob siv qhov chaw tus IP.
Kauj ruam 1. Ntaus cov nram qab no ntawm kab lus qhia ntawm lub zos:
% xhost + 17.200.10.5
Kauj ruam 2. Nkag mus rau cov chaw taws teeb chaw:
% telnet 17.200.10.5
Kauj Ruam 3. Ntawm cov chaw taws teeb chaw (los ntawm kev sib txuas lus nyob rau hauv lub xov tooj), qhia cov chaw taws teeb nrais kom pom cov qhov rais ntawm cov chaw hauv zos los ntawm sau:
% setenv DISPLAY 128.100.2.16 Nyiaj Seev Cev 1.0
(Es tsis txhob setenv koj yuav tau siv cov khoom xa tawm ntawm qee tus qauv.)
Kauj Ruam 4. Tam sim no koj tuaj yeem khiav software rau cov chaw taws teeb chaw. Piv txwv, thaum koj ntaus ntawv xterm nyob rau hauv cov chaw taws teeb sab nraud, koj yuav tsum pom xterm qhov rais ntawm tus tswv tsev hauv zos.
Kauj ruam 5. Tom qab koj tas, koj yuav tsum tshem tawm cov chaw nres nkoj sab nraud ntawm koj daim ntawv tswj raws li hauv qab no. Nyob rau hauv lub zos party hom:
% xhost - 17.200.10.5
Ceev Ntaub Ntawv
Txoj kab lus xhos tsuas muaj ob peb qhov kev hloov los pab koj nrog koj txoj kev sib tham:
- xhost + hostname : Ntxiv hostname rau X neeg rau zaub mov kev tswj cov ntaub ntawv.
- xhost - hostname : Tuskheej hostname ntawm X neeg rau zaub mov kev tswj xyuas cov npe.
- xhost + : Tshem tawm txoj kev tswj hwm (tag nrho cov hom kev sib txuas lus yuav tau mus rau X neeg rau zaub mov)
- xhost - : Hloov kev tswj xyuas rov qab.
Vim hais tias Linux distributions thiab ntsiav-tso qib sib txawv, siv tus txiv neej hais kom ua ( % txiv neej ) pom li cas xhost yog muab los siv rau hauv koj qhov chaw xam phaj.
