Lub nslookup nqi hluav taws xob yog ib txwm ntsia rau ntawm ob lub Linux thiab Windows, yog li koj tsis tas yuav rub tawm txhua cov programs. Cov syntax ntawm nws cov yuam sij yog tib yam hauv ob qho kev ua haujlwm. Khiav nws zoo li no:
nslookup -type = mx server.domain, qhov twg server.domain yog lub npe sau npe.
Hauv kev teb, koj yuav tau txais tag nrho cov ntaub ntawv koj xav tau. Hauv cov npe uas tso tawm ntawm qhov screen, them sai sai rau cov kab uas muaj kev sib txuas ntawm cov tsiaj ntawv mx - cov no yog cov ntaub ntawv hais txog cov servers npaj rau txais cov ntawv. Koj tsis tas yuav muaj cov ntaub ntawv hais txog lwm tus servers.

Yog tias cov kab hais kom ua kab sab tau pib nyob rau hauv hom window, luam tag nrho cov ntaub ntawv tsim nyog rau daim ntawv teev cia, thiab los ntawm qhov ntawd mus rau ib qho ntawv xov xwm twg, thiab tom qab ntawd kaw lub console. Thaum ua haujlwm nyob rau hauv hom ntawv nyeem, koj yuav tsum sau dua cov ntaub ntawv tau txais manually. Txhawm rau zam qhov no, siv kev tsim kho no:
nslookup -type = mx server.domain> text.txt
Kev tsim tawm los ntawm nslookup nqi hluav taws xob yuav theej rau cov ntawv text.txt (koj tuaj yeem sau nws txawv).
