tso tawm , ib qho kev ua tau zoo tso cai DNS neeg rau zaub mov (tus recursor yog tsim los ua ib daim ntawv thov cais) uas txhawb nqa tag nrho cov peev txheej DNS niaj hnub. Qhov project yog tsim los ntawm Czech lub npe sau npe CZ.NIC, sau ua C thiab muaj ntawv tso cai raws li GPLv3.
KnotDNS yog qhov txawv los ntawm nws txoj kev tsom mus rau kev ua haujlwm zoo ntawm cov lus nug, uas nws siv ntau txoj xov thiab feem ntau tsis thaiv kev siv uas ntsuas tau zoo ntawm SMP systems. Nta xws li ntxiv thiab tshem tawm thaj chaw ntawm ya, hloov chaw ntawm servers, DDNS (dynamic hloov tshiab), NSID (RFC 5001), EDNS0 thiab DNSSEC txuas ntxiv (xws li NSEC3), teb tus nqi txwv (RRL) yog muab.
Hauv qhov kev tso tawm tshiab:
- Ntxiv kev ua tau zoo network hom, siv los ntawm subsystem (eXpress Data Path), uas muab cov cuab yeej rau kev ua cov pob ntawv ntawm lub network tsav theem ua ntej ua tiav los ntawm Linux kernel network pawg. Txhawm rau siv hom, Linux ntsiav 4.18 lossis tom qab yog xav tau.
- Ntxiv kev txhawb nqa rau Catalog Zones, ua kom yooj yim los tswj cov DNS servers thib ob. Thaum cov yam ntxwv no tau qhib, es tsis txhob txhais cov ntaub ntawv sib cais rau txhua cheeb tsam thib ob ntawm tus neeg rau zaub mov thib ob, ib cheeb tsam catalog raug xa mus ntawm cov thawj thiab thib ob servers, tom qab uas cov cheeb tsam tsim ntawm thawj tus neeg rau zaub mov thiab cim raws li suav nrog hauv phau ntawv teev npe yuav raug txiav. tsim rau ntawm tus neeg rau zaub mov thib ob yam tsis tas yuav hloov kho cov ntaub ntawv teeb tsa. Cov khoom siv hluav taws xob kcatalogprint tau thov rau kev tswj hwm catalog.
- Ntxiv DNSSEC pov thawj hom tshiab.
- Ntxiv kzonesign qhov hluav taws xob rau manually tsim cov kos npe digital rau DNSSEC.
- Ntxiv kxdpgun kev siv hluav taws xob nrog kev ua haujlwm siab "DNS dhau UDP" lub tshuab hluav taws xob rau Linux.
- kdig ntxiv kev txhawb nqa rau DNS dhau HTTPS (DoH), siv GnuTLS thiab libnghttp2.
- Ntxiv kev txhawb nqa rau phau ntawv DNSSEC qhov tseem ceeb tswj yuam sij KSK (Key Signing Key) ().
- Ntxiv kev txhawb nqa rau kev txiav txim siab tsim cov cim kos npe siv ECDSA algorithms (yuav tsum tau GnuTLS 3.6.10 thiab tom qab ntawd ua haujlwm).
- Txoj hauv kev nyab xeeb rau thaub qab thiab rov qab cov ntaub ntawv DNS cheeb tsam tau npaj tseg.
- Qhov kev ua tau zoo ntawm "statistics" module tau txhim kho zoo.
- Thaum koj ua kom muaj ntau txoj xov ntawm kev tsim cov ntawv kos npe digital rau thaj chaw DNS, kev sib piv ntawm qee qhov kev ua haujlwm ntxiv nrog cov cheeb tsam tau lees paub.
- Txhim kho caching efficiency thiab txhim kho cov lus nug kev ua tau zoo.
