KnotDNS 2.9.0 DNS Server Kutulutsidwa

Lofalitsidwa kumasula KnotDNS 2.9.0, seva yovomerezeka ya DNS yogwira ntchito kwambiri (recursor idapangidwa ngati pulogalamu yosiyana) yomwe imathandizira mphamvu zonse zamakono za DNS. Ntchitoyi ikupangidwa ndi Czech name registry CZ.NIC, yolembedwa mu C ndi wogawidwa ndi zololedwa pansi pa GPLv3.

KnotDNS imasiyanitsidwa ndi kuyang'ana kwake pakukonza kwamafunso apamwamba, komwe imagwiritsa ntchito njira zambiri komanso zosatsekereza zomwe zimayendera bwino pamakina a SMP. Zinthu monga kuwonjezera ndi kuchotsa madera pa ntchentche, kusamutsa madera pakati pa ma seva, DDNS (zosintha zosintha), NSID (RFC 5001), EDNS0 ndi DNSSEC zowonjezera (kuphatikiza NSEC3), kuchepetsa kuyankha (RRL) kumaperekedwa.

M'kutulutsa kwatsopano:

• Thandizo lathunthu lakhala likugwiritsidwa ntchito pa mawerengedwe osiyanasiyana a ma serial manambala (SOA) pazigawo pa ma seva ambuye ndi akapolo, pamene chigawocho chikutsimikiziridwa ndi siginecha ya digito pa seva ya kapolo;
• Thandizo lowonjezera la marekodi okhala ndi ma wildcards ku module ya geoip;
• Makonda atsopano a 'rrsig-pre-refresh' awonjezedwa ku DNSSEC kuti achepetse kuchuluka kwa zochitika zotsimikizira siginecha ya digito;
• Anawonjezera "tcp-reuseport" kukhazikitsa SO_REUSEPORT(_LB) mode ya TCP sockets;
• Anawonjezera "tcp-io-timeout" kukhazikitsa kuti muchepetse nthawi yolowera I/O pa TCP;
• Kuchita kwa ntchito zosintha zone kumawonjezeka kwambiri;
• Thandizo lokonzanso zolumikizira maukonde ndi zowongolera zathetsedwa, chifukwa sizingachitike ndondomekoyi itakhazikitsanso mwayi;
• Kukonzanso kukhazikitsidwa kwa ma Cookies a DNS kuti agwirizane kwathunthu ndi zolemba-ietf-dnsop-server-cookies;
• Mwachikhazikitso, malire a kugwirizana kwa TCP tsopano ali ochepa kwa theka la ndondomeko ya fayilo yofotokozera malire, ndipo chiwerengero cha mafayilo otseguka tsopano chili ndi 1048576;
• Posankha chiwerengero cha ogwira ntchito omwe adayambitsidwa, chiwerengero cha CPUs tsopano chikugwiritsidwa ntchito, koma osachepera 10;
• Zosankha zambiri zasinthidwanso, mwachitsanzo 'server.tcp-reply-timeout' kupita ku 'server.tcp-remote-io-timeout', 'server.max-tcp-clients' kukhala 'server.tcp-max-clients', 'template. journal-db' mpaka 'database.journal-db', etc. Thandizo la mayina achikulire lidzasungidwa mpaka kumasulidwa kwakukulu kotsatira.
