Rau kev siv hauv Fedora 33 , uas teeb tsa kev faib khoom siv systemd- daws los ntawm lub neej ntawd rau kev daws cov lus nug DNS. Glibc yuav raug tsiv mus rau nss- daws teeb meem los ntawm qhov project systemd es tsis txhob ntawm lub built-in NSS module nss-dns.
Systemd-kev daws teeb meem ua haujlwm xws li tswj cov chaw hauv cov ntaub ntawv resolv.conf raws li DHCP cov ntaub ntawv thiab kev teeb tsa DNS zoo li qub rau kev sib txuas hauv network, txhawb nqa DNSSEC thiab LLMNR (Txuas Lub Zos Hauv Zos Multicast Name Resolution). Ntawm qhov zoo ntawm kev hloov mus rau qhov kev daws teeb meem yog kev txhawb nqa rau DNS dhau TLS, muaj peev xwm ua kom lub zos caching ntawm DNS queries, thiab kev txhawb nqa rau kev khi sib txawv rau cov sib txawv network interfaces (nyob ntawm lub network interface, DNS server raug xaiv hu rau , piv txwv li, rau VPN interfaces, DNS queries yuav raug xa los ntawm VPN). Tsis muaj kev npaj siv DNSSEC hauv Fedora (systemd- daws teeb meem yuav tsim nrog DNSSEC = tsis muaj chij).
Systemd-kev daws teeb meem twb tau siv los ntawm lub neej ntawd hauv Ubuntu txij li 16.10 tso tawm, tab sis kev sib koom ua ke yuav ua tiav txawv hauv Fedora - Ubuntu tseem siv cov tsoos nss-dns los ntawm glibc, i.e. glibc tseem tuav /etc/resolv.conf, thaum Fedora npaj hloov nss-dns nrog systemd's nss- daws. Rau cov neeg uas tsis xav siv systemd-resolved, nws yuav muaj peev xwm lov tes taw nws (koj yuav tsum deactivate lub systemd-resolved.service kev pab cuam thiab restart NetworkManager, uas yuav tsim cov tsoos /etc/resolv.conf).
